The issue on whether or not poor regions tend to catch-up richer ones
plays a significant role in regional growth theory. The empirical growth
models were relying more on available data such as real per capita income,
savings and investment, government expenditures, exports, labor force and
its structure by industries, education variables like school enrollment, etc.
The concept of economic convergence according to Matkoski and
Prochanik (2004) should be address in two aspects. First, a tendency
towards leveling (equalization) per capita incomes and growth rates among
counties (regions). Second, tendency toward economic cycle convergence
(that is ups and downs of economic cycles ideally should conform). Both
convergence concepts are independent and tested separately. In ourresearch
we address only first part of the issue, for it is assumed that within
boundaries of one country economic cycles should coincide due the
equality of macroeconomic conditions.

Social connections and interactions are becoming more complicated and requirements for all members of society are rising in the process of social development. Companies’ actions towards these requirements are predicated on the environmental and social responsibility of enterprises. It is impossible to understand the state of the modern business and the role that it can play under the new conditions without analyzing the changes that have occurred over the past decades.

The important concept of equilibrium has always been controversial in ecology, but a new, more general concept, an asymptotic environmentally determined trajectory (AEDT), overcomes many concerns with equilibrium by realistically incorporating long-term climate change while retaining much of the predictive power of a stable equilibrium. A population or ecological community is predicted to approach its AEDT, which is a function of time reflecting environmental history and biology. The AEDT invokes familiar questions and predictions but in a more realistic context in which consideration of past environments and a future changing profoundly due to human influence becomes possible. Strong applications are also predicted in population genetics, evolution, earth sciences, and economics.

Ecological networks are complex systems forming hierarchical structures in which energy and matter is transferred between the network’s compartments. Predicting energy flows in food webs usually involves complex parameter-rich models. In this thesis, the application of the principle of maximum entropy (MaxEnt) to obtain least biased probability distributions based on prior knowledge is proposed as an alternative to predict the most likely energy flows in food webs from the network topology alone. This approach not only simplifies the characterisation of food web flow patterns based on little empirical knowledge but can also be used to investigate the role of bottom-up and top-down controlling forces in ecosystems resulting from the emergent phenomena based on the complex interactions on the level of species and individuals. The integrative measure of “flow extent”, incorporating both bottom- up and top-down controlling forces on ecosystems, is proposed as a principle behind ecosystem evolution and evaluated against empirical data on food web structure. It could be demonstrated that the method of predicting energy flow with the help of MaxEnt is very flexible, applicable to many different setting and types of questions in ecology, and therefore providing a powerful tool for modelling the energy transfer in ecosystems. Further research has to show in how far the most likely flow patterns are realised in real-word ecosystems. The concept of flow extent maximisation as a selection principle during ecosystem evolution can enhance the understanding of emergent phenomena in complex ecosystems and maybe help to draw a link between thermodynamics and ecology.

Resumo: Nesta tese propomos um desenvolvimento do conceito de especialização no uso de recursos, de forma a incluir aspectos pouco considerados, principalmente no contexto de interações: afinidades entre os tipos de recursos, sua disponibilidade e padrões de coocorrência. Por meio da incorporação de avanços recentes em estudos ecofilogenéticos e em modelos nulos, propomos novas métricas para a especialização de espécies e comunidades, e aplicamos esses avanços para responder a questões particulares. No primeiro capítulo, o arcabouço conceitual é apresentado de forma mais geral, e uma métrica para a especialização de espécies é proposta e exemplificada. O segundo capítulo, de natureza metodológica, estende essa métrica para comunidades e propõe uma partição da variação em especialização entre espécies e entre locais de forma hierarquizada. O terceiro capítulo investiga a capacidade destas ferramentas de evidenciar relações entre a especialização e a distribuição geográfica de espécies de insetos endófagos de capítulos de Asteraceae no Brasil. Por fim, o quarto capítulo utiliza o mesmo conjunto de dados para investigar o papel da diversidade filogenética de recursos na determinação da riqueza de insetos que os utilizam
Abstract: In this thesis we propose a development of the resource specialization concept to include aspects usually not taken into account, especially for trophic interactions: affinities among resource types, their availabilities and cooccurrence patterns with consumers. By incorporating recent advances in ecophylogenetics and null modelling, we propose new metrics for the specialization of species and communities and apply these advances to address particular questions. In the first chapter the general conceptual framework is presented and a metric for the specialization of species is proposed and exemplified. The second chapter, mostly methodological, expands this metric for communities and proposes a hierarchical partitioning of the variation in specialization among species and locations. The third chapter tests this toolset in showing the relationship between specialization and geographic distribution ranges of endophagous insects feeding in Asteraceae flowerheads in Brazil. Finally, the fourth chapter uses the same dataset to investigate the role of phylogenetic diversity of resources in determining the richness of insect herbivores using them

Der volle Inhalt der QuelleAnnotation:
The purpose of this study was to examine the relationship between culture, affordance and proficiency. Further, to study the possibility of a cognitive gap between artists and the audience they design for, akin to the Designer-User gap in interaction design and user experience research. In order to contextualize the issue studied, relevant theories in ecological psychology, visual literacy, image interpretation and cognitive models are presented and discussed alongside contemporary industry issues that may have arisen from this type of cognitive gap. As artist and audience might have these vastly different interpretations of identical visual material, conveying or communicating specific design ideas or aesthetics may be compromised or lost in translation, negatively influencing visual communication. The study compared a set of individuals matching either the label of concept artist or target game audience on their unmediated reactions and mental heuristics when encountering a novel design from a familiar genre, using a method of concurrent verbalization. Results were discussed and compared to prevailing theories in cognition, user experience design and the presented research question. Said results indicate that there are distinct variations between how artists and audience apply their heuristics for unmediated design interpretation, although it also provides a few tentative suggestions as to a few methods in which said issue could be circumvented or surmounted.

Der volle Inhalt der QuelleAnnotation:
It is deduced that a sub-humid, maritime-cool temperate, mixed broadleaf-podocarp forest probably covered most of Quail Island in pre-settlement times. It is likely that the island was deforested by early Polynesian settlers. The occurrence of forest precursors, the presence of forest remnants in environmentally analogous sites elsewhere, as well as the healthy state of natives planted in 1983 are indicative that forest recovery processes are still active and Quail Island retains a forest environment.
In the development of a restoration philosophy for Quail Island, a values system is proposed that enables all species to be viewed in terms of their functional role in the contemporary ecosystem. The perceived restoration goal is to both reinitiate and speed up the native forest recovery processes on Quail Island.
The main environmental restoration constraints are the presence of rabbits and mustelids. A social impact assessment scoping exercise revealed near-universal support for the concept, although the Department of Conservation is divided over support for the concept and this poses the main cultural constraint. The concerns of the principal stakeholders are mediated through the modern ecotourism paradigm within the framework of a proposed variant of the Biosphere Reserve concept.
The process of restoration should be guided through a Medium Interference
Management strategy that aims to mimic forest recovery processes through the development of strategically placed "forest cells". Lists of species for selection are based on those that are present in sites environmentally analogous to Quail Island. Scrubby woody cover could be attained in 10-15 years and a low forest canopy could be achieved in 20-25 years. Eight locally extinct forest bird species are suggested for translocation along with one coastal species. Four species of reptiles are also considered. A monitoring scheme is suggested to gauge success and progress.

The Ecological Q-Sort was developed specifically for the measurement of self-concept in older adults. Self-concept is defined as individuals' perceptions of themselves in relationship to their environment. Consequently, self-concept is contextual, multidimensional and varies with the situation. The Ecological Q-Sort was subjected to convergent and discriminant validational procedures in the present study. Correlational analyses provided support for both convergent and discriminant validity, suggesting that this instrument measures ecological, domain specific self-concept in older persons. However, multivariate analysis of variance did not yield significant main effects or interactions for sex, marital status, and health as observed on the sets of ecological and non-ecological self-concept measures.

This thesis was performed at Harvest Moon who develops methods to reuse the nutrients in human waste and has developed technology for these methods. The project aimed to explore how their technology could be implemented in a boat toilet for the Swedish recreational market. It resulted in a proof-of-concept boat toilet. Firstly, the user group and the current sanitation system were explored, through literature research and interviews with the user group. Sailing craft users were identified to be the user that would gain the most value with these technologies. The two largest problems for the users with the current system was a low septic tank capacity and problems emptying it. The proof-of-concept was developed by developing one component at a time, starting with the most central component that most components were dependent on and between the components looking at the overarching architecture. To test the component ideas and gain quick answers to their functions rapid prototyping were used. The work was done in close collaboration with Harvest Moon and the results were continuously used in their own projects that were performed in parallel. The results of the thesis were presented as CAD models and illustrations of the architecture and of the usage of the boat toilet. The resulting concept would provide the user with a better sewage capacity than current technologies, which would result in longer times between having to empty the toilet. It would also provide a simpler and more pleasant experience emptying the toilet. The toilet waste would also be easier to use in a system were the nutrients are reused than the current sanitation system.Det här examensarbetet utfördes hos Harvest Moon som arbetar med metoder att ta tillvara på näringsämnena i toalettavfall och har utvecklat tekniker för dessa. Projektet skulle undersöka hur deras tekniker skulle kunna implementeras i svenska fritidsbåtar i form av en proof-of-concept toalett. Först undersöktes användargruppen och dagens sanitetssystem inom svenska fritidsbåtar, genom litteratur inom ämnet samt intervjuer med användaren. Den grupp som skulle få mest värde av en toalett med denna teknik var segelbåtar och de två största problemen med dagens teknik var att man hade låg kapacitet på tanken och att det var problem med att tömma tanken. Proof-of-concept utvecklades genom att utveckla en komponent i taget, där den komponent som var mest central och styrde andra börjades med för att mellan varje komponent titta på helheten. Prototypbygge användes mycket för att testa komponenterna och få snabba svar på hur de fungerade. Arbetet skedde i nära samarbete med Harvest Moon och resultaten ingick i deras egna projekt som pågick parallellt. Resultatet presenterades i CAD-modeller och illustrationer om hur arkitekturen såg ut, samt hur den var tänkt att användas. Det resulterande konceptet skulle ge användaren en mycket bättre kapacitet, vilket skulle resultera i längre tider mellan att man behöver tömma avfallet och en enklare och behagligare tömningsupplevelse. Avfallet skulle även lättare än dagens system kunna anslutas till ett system för att återanvända näringsämnena i avfallet.

Self-concept has been defined as being both contextual and multidimensional, varying with different situations and states of being. In this light, the Ecological Q-Sort was developed to measure the varying nature of self-concept in older persons. The purpose of this study is to determine what contextual selves are represented within the framework of the Ecological Q-Sort. The cards of the test were rated and Ward's Hierarchical Clustering technique was utilized to categorize the cards along two dimensional rating factors. Statistical analysis revealed that social, productive, physical, play, active, assertive, and nurturing selves are represented .by the instrument. Those selves are measured by the Loneliness/Sociability, Productive/Relaxation, Vitality/Instability, Initiative/Inefficacy, Confidence/ Uncertainty, and Nurturing/Loss categories.

This doctoral dissertation examine the specific role of the self-concept and of its different dimensions on the evolution of anorexic symptoms over a period of 140 consecutive days. in two different samples comprising 26 anorexic outpatients and inpatients and in 23 girls without eating disorders (ED). By applying an idiographic approach, the main results show that the level, instability and dynamic of self-concept dimensions, and more precisely of body attractiveness, represent potent predictors of psychological, behavioral (e.g. full score of Eating Disorders Inventory-Adolescent, EDI-A-24) and somatic (e.g. Body Mass Index, BMI) anorexic symptoms over medium (i.e. over a few months), short (i.e. over a few weeks) and very short (i.e. over a few days) periods of time. Moreover, multivariate regression analyses further show that the pattern of association between anorexic symptoms and self concept dimensions remains the same in both samples (anorexic and without ED). Moreover, the results of cross-correlations analyses reveal that anorexic symptoms are as unstable as the dimensions of self-concept, with which they appear to be intertwined. More precisely, body attractiveness, most often a) precedes the drive for thinness, b) is associated to bulimia according to a"vicious circle" phenomenon, and c) fluctuates with according to body dissatisfaction. However body attractiveness was not found to relate to anorexic girls final status at the end of the follow-up period (e.g. deterioration, improvement, stabilization, etc). Finally, the results from a qualitative analysis suggest that social events experienced as positive contribute to the improvement of anorexia nervosa.This appears to be explained by the potential of these events to break through anorectic girls known ego-centered tendencies. Taken as a whole, the 'results highlight the necessity of considering overall of dimensions of self-esteem and the"profiles" of girls with and without ED in preventive and therapeutic interventions for ED.

There is an appetite for market based management mechanisms in agri-environmental policy. The purpose of this study is to explore how the market based concept of ecological goods and services
(EGS) can be applied towards the management of an agricultural externality in British Columbia,
Canada. Through literature review I establish the importance of valuation in market based
management. With an EGS program in mind I identify the City of Abbotsford as a potential ecological
service buyer and establish economic value for improvements to water quality in the Abbotsford-Sumas aquifer. I use a replacement cost approach based on the present value costs of the proposed Stave Lake surface water system. My results suggest that if nitrate remediation and/ or nitrate management practices improve water quality and the costs fall below $168 million there are potential net benefits to the City of Abbotsford. This value could form the basis for a city program or EGS trading scheme to encourage farmers to place a higher priority on water quality in their land management practices. A key finding is that lack of information on the degree to which nitrate contamination constrains well field development limits the ability to conclusively evaluate the net benefits of improved nitrate
management and proceed with an EGS program.

This study explores the concept of feedback from various perspectives in psychology and cognitive science. Specifically, the theories of ecological psychology, situated and Distributed Cognition, Cognitive Systems Engineering and Embodied cognition are investigated and compared. Cognitive Systems Engineering provides a model of feedback and related constructs, to understand human behavior in complex working environments. Earlier theories such as ecological psychology, considered feedback as direct perception. Situated cognition clearly inherits ideas from ecological psychology, whereas distributed cognition provides a deeper understanding of feedback through artifact use. Cognitive Systems Engineering provides a systematic view of feedback and control. This framework is a suitable perspective to understanding feedback in human-machine settings.

This study examines a range of South African speculative novels which situate their narratives in futuristic or ‘alternative’ milieus, exploring how these narratives not only address identity formation in a deeply divided and rapidly changing society, but also the ways in which human beings place themselves in relation to Nature and form notions of ‘ecological’ belonging. It offers close readings of these speculative narratives in order to investigate the ways in which they evince concerns which are rooted in the natural, social and political landscapes which inform them. Specific attention is paid to the texts’ treatment of the intertwined issues of identity, belonging and ecological crisis. This dissertation draws on the fields of Ecocriticism, Postcolonial Studies and Science Fiction Studies, and assumes a culturally specific approach to primary texts while investigating possible cross-cultural commonalities between Afrikaans and English speculative narratives, as well as the cross-fertilisation of global SF/speculative features. It is suggested that South African speculative fiction presents a socio-historically situated, rhizomatic approach to ecology – one that is attuned to the tension between humanistic- and ecological concerns.

Miri, Ehsan Mohammadzadeh. „Ecological building design : a proof of concept and identifying the factors which deter the use of Iranian vernacular principles in modern architecture“. Thesis, London South Bank University, 2016. http://researchopen.lsbu.ac.uk/1242/.
Der volle Inhalt der QuelleAnnotation:
Previous research has shown that there is a strong link between people, buildings and climate: the building sector contributes up to 30 per cent of global annual greenhouse gas emissions and consumes up to 40 per cent of all energy. Most 20th-century buildings in the world are currently reliant on electro-mechanical cooling systems. Researchers and scholars have studied and analysed the sustainability issues in architecture casting light from different perspectives. However, such studies have seldom paid significant attention to the principles of sustainable Iranian architecture. Environmental sustainability and sustainable architecture in Iran are still relatively new concepts. This research fills the gap on the application of vernacular architecture to modern building design, particularly in the context of Iran and its climate by creating an informed and tested understanding of how vernacular architecture can inform modern building design and techniques. There have been limited studies on vernacular design as a source of knowledge which can contribute to 21st century challenges. The scope of this study is not only limited to Iran as its finding are also applicable to other countries with hot climates. As one of the key contributions, this thesis demonstrates how energy use in buildings can be minimised using such principles that are adopted from Iranian vernacular architecture. The study firstly relies on the state of the art literature review on vernacular architecture in Iran using secondary analysis, and then offers comparisons, analysis and hypotheses testing in the following sections. The challenge of extracting Iranian vernacular architecture principles (IVAP) has been achieved by a multi-method approach. Site observations, sketches, drawings and measurements at the early stages were reinforced by further detailed analysis of the literature beyond IVAP, and supplemented by studies in sustainable design such as passive design. It was found that IVAP have many common elements which are shared today by passive design. The methodology for the above consists of simulation modelling and comparisons of the energy in use for building designed using IVAP versus designs using conventional building techniques in Iran. By using energy software packages (Integrated Environmental Solutions, Design Builder, CC5) it is found that the application of IVAP can significantly improve energy consumption in buildings. The research also explores a novel approach and tests the feasibility of using ‘adobe’ as an insulation material for construction of walls. The analysis involves construction of a wall using this new approach (inspired by IVAP) and testing it in the lab for its energy performance. The findings confirm that as a building material, ‘adobe’ could be potentially a feasible and environmentally friendly substitute to conventional insulation with additional sustainable benefits such as using local materials and preservation of traditional culture in the region. Another contribution of this study is to offer a deeper understanding of the drivers and barriers to the implementation of IVAP in today’s architecture in Tehran, Iran. To achieve this a survey was conducted which revealed that an integral part of the implementation and application of IVAP is education and design of the UG and PG curricula. Recommendations are made to highlight the necessary and critical adjustment to policies regarding promotion of IVAP to safeguard the environment and national and cultural identities.

Der volle Inhalt der QuelleAnnotation:
This thesis focuses on the trajectory of the biomedical concept of virulence from 1880 until the present. Following the concept across disciplinary boundaries, from a longue durée history perspective, it explores how virulence was shaped through two distinct, although sometimes overlapping, “styles of reasoning”. Located at the intersection of several distinct research domains in biology and medicine, the concept of virulence provides, in addition, a window into the complex and changing relations between evolutionary biology and the health sciences (broadly construed) over the past two centuries. Moving back and forth between field experiments and the laboratory, this work examines, through the lens of historical epistemology, the emergence of what I call the molecular and the ecological styles, and their respective conceptual practices. It focuses on the ways in which these styles operationalize the distinction between virulent or avirulent organisms in sometimes opposite sense: Whereas in the molecular (or endogenous) style the expression of virulence is explained by properties of internal structures of the infectious agent (e.g. polysaccharide capsule, virulence gene, or pathogenicity island), the concept of virulence in the ecological (or exogenous) style reflects, in contrast, either a lack of adaptation between two species (avirulence hypothesis) or the existence of one or more ecological compromises between, say, the mode of transmission of a pathogen and its host’s recovery rate (trade-off model). Both styles can be said to originate in the medical bacteriology of the late-nineteenth century, but while the former grew mostly out of the work of Louis Pasteur and Robert Koch in Europe, the latter was primarily shaped by Theobald Smith in the United States. Nearly a century later, the introduction of the category of emerging infectious disease within public health discourses in the mid-1990s facilitated a rapprochement between the two styles that had, so far, remained apart. Employing the 1918–1919 influenza pandemic as an example in which to illustrate the trajectory of the molecular and the ecological approaches, the diversity of explanatory schemes developed to account for the pandemic’s exceptional virulence points toward an unresolved, and yet productive, epistemic tension between the two styles, on the one hand, and the intrinsic polarity of the concept of virulence itself, on the other.

Les chênes sessiles et pédonculés sont deux espèces sympatriques interfertiles occupant des places distinctes dans la succession écologique. Elles constituent pour cela un bon modèle pour l’étude de la spéciation écologique. Malgré leur écologie contrastée, les deux espèces de chênes coexistent naturellement dans de nombreuses forêts, rendant possible l’étude de leur système de reproduction intra- et interspécifique. Des travaux précédents ont suggéré que l’hybridation entre ces deux espèces serait fréquence-dépendante. Elle dépendrait de la proportion de pollen allospécifique (c'est-à-dire de pollen de l’autre espèce) que reçoit l’arbre mère étudié. Ce phénomène d’hybridation fréquence-dépendante est appelé effet Hubbs, du nom d’un ichtyologue qui découvrit ce mécanisme en 1955. Mon travail a consisté à étudier, dans une parcelle mixte de chênes, les barrières à l’hybridation qui permettent la coexistence de ces deux espèces. Pour cela, j’ai effectué une étude de paternité de grande ampleur (près de 3500 individus typés sur 12 marqueurs microsatellites). Tout d’abord, je me suis intéressée à la délimitation des deux espèces en appliquant pour la première fois in situ le critère d’interfertilité. Je me suis ensuite concentrée sur les facteurs qui influencent l’hybridation au travers d’une modélisation des croisements à l’échelle de l’individu. Les résultats montrent que le maintien de ces deux espèces est régi par deux composantes environnementales importantes : la fréquence de chaque espèce et leur distribution, qui influencent la quantité de pollen reçue. Grâce à cette étude empirique et à l’approche de modélisation de ces croisements, nous avons désormais une bien meilleure vision de l’effet de l’environnement sur l’hybridation. J’ai par la suite comparé les caractéristiques du système de reproduction de chaque espèce (dispersion du pollen et fécondité mâle) en cherchant si un lien existait avec leur stratégie écologique. Les résultats suggèrent que les différences de dynamique écologique pourraient être à l’origine de la spéciation du fait de l’existence de compromis différents en termes d’allocation de ressources mais qu’à plus court terme la stabilité de l’environnement est essentielle au maintien des espècesQuercus petraea and Q. robur are two interfertile sympatric species. They occupy distinct stages during forest succession and constitute therefore good models for ecological speciation studies. Despite their differences, they often grow together in mixed stands, allowing the study of their intra- and interspecific reproductive system. Hybridization between these two oak species has been suggested to be frequency-dependent. The effect of the relative species abundance on hybridization is known as the “Hubbs’ effect”, from the name of an ichthyologist who described this mechanism in 1955. My work was to study the processes that limit hybridization between these two species, thereby allowing their coexistence. I conducted an extensive paternity analysis (almost 3500 individuals genotyped at 12 microsatellite markers). First, I tried to delimitate the two oak species by applying for the first time in situ the interfertility criterion. Then, I focused on interspecific crosses by studying those factors influencing hybridization. Results showed that the maintenance of these two species depends on the frequency of each species and their distribution, as both factors influence the quantity of pollen received by female flowers. Thanks to this empirical study and to this modeling approach, we have now a much better view of environmental effects on hybridization. I then compared the characteristics of the reproductive system of each species (pollen dispersal and male fertility) in relation with their ecological strategies. The results suggest that differences in species ecological dynamics are at the origin of the speciation process but that at a finer scale the stability of the environment is crucial for species’ maintenance

Societal marketing - marketing based on socially or environmentally conscious attributes, has for many years been considered an accepted chapter of marketing theory. However, consumer response to many socially-conscious products never met expectations - prompting marketing researchers to re-examine the assumptions underpinning the societal marketing theory. One such assumption is that, given consumer concern for environmental and social issues, there is a positive, significant relationship between consumer societal knowledge and the purchase of socially-conscious products. However, the few studies which have examined this relationship have failed to provide consistent results, and thus the nature of the relationship remains unclear. It is argued within this thesis that the equivocation of results may have been a methodological artefact, as investigations often used general rather than specific measures and excluded moderating variables from their theoretical models. Adopting a mixed-method approach, this study first used qualitative interviews to identify moderating variables which may impact the relationship between the knowledge and purchase. The identified potential moderating variables were then incorporated into quantitative, survey research which was used to examine the nature of the relationship between consumer societal knowledge and the purchase of socially-conscious products. The study found that the relationship between the variables is both positive and significant, but weak. The results revealed that one contextual variable, Health, moderated the relationship between knowledge and purchase. The results also suggest the more traditional product attribute of price remains the most significant predictor of purchase - far greater than the consumers' societal knowledge.

Comprise pendant longtemps comme une entité sui generis dont les origines ne pouvaient être expliquées que par rapport à elle-même («omnis cultura excultura»), la notion de culture n’est plus le maître-mot du «culturalisme». Le naturalisme n’a pourtant pas non plus fini de faire d’elle une catégorie complètement naturalisée. Dans cette thèse, je propose une approche analytique et synthétique du concept éthologique de culture. Je pars de ses racines historiques, notamment autour de la notion de cultures ou traditions animales, en examinant le paysage épistémologique des mots-clés des auteurs publiant dans ce domaine, ainsi qu’en évaluant les engagements théoriques et philosophiques associés à certaines définitions de la culture. L’adaptationnisme méthodologique est également mis en œuvre pour révéler dans ce travail l’ampleur des conflits stratégiques, au sens de la théorie des jeux, présents dans certaines formes de transmission culturelle. L’ensemble nous mène à faire le bilan de ce que l’on a appelé la révolution éthologique dans la notion de culture, en soulignant les dimensions écologiques qui sont maintenant mises en avant, mais aussi les limites d’un concept qui précède de plusieurs siècles la compréhension scientifique des phénomènes concernésLong time understood as a sui generis entity whose origins could only be explained in relation to itself ("omnis cultura ex cultura"), the notion of culture is no longer the watchword that "culturalism" made of it. Naturalism, however, has not ended up turning culture into a completely naturalized category either. In this dissertation, regarding the ethological concept of culture, I am advancing an approach that is both analytic and synthetic. The historical roots of the notion of animal cultures (or animal traditions) are my starting point. Then follows a scrutiny of the epistemological landscape of author keywords in the field of animal cultures. An assessment of certain theoretical commitments and different philosophical positions associated to several definitions of culture is also offered. In addition, methodological adaptationism is put to work to reveal the scope of certain strategic conflicts that arise in a game-theoretic fashion in certain forms of cultural transmission. The whole enterprise allows us to take stock of what has come to be called the ethological revolution regarding the notion of culture. This is accomplished by underlining the ecological dimensions but also the limitations of a concept that, after all, predates by several centuries the scientific understanding of the phenomena it is purported to cover

As teorias sobre a formação dos conceitos em Ciência da Informação carecem de uma abordagem mais profunda sobre o principal objeto desta disciplina: a informação. Esta pesquisa realiza uma reflexão sobre essa carência tendo como estratégia considerar o problema da definição de informação e conceito como interdependentes. Essa estratégia define o problema enquanto fenômeno (como a informação interage com a formação dos conceitos?) e não a partir dos diversos exercícios de tentar definir esses conceitos. O objetivo da pesquisa é pautado, portanto, pela compreensão do fenômeno nos domínios-chave onde a informação e os conceitos se desdobram e se complementam: o cognitivo, o social e o comunicacional. Essa compreensão requer, contudo, uma abordagem diferenciada para a questão da informação, na qual esta participe do processo de organização destes domínios, abandonando assim a perspectiva tradicional da informação como ocorrências comunicativas ou efeitos dos eventos sobre a mente. A hipótese da tese era que essa perspectiva tradicional, generalista, de informação, gera uma compreensão cognitivista da formação dos conceitos, amparada em um paradigma dualista da cognição sob a dicotomia objetivo/subjetivo. O objetivo da pesquisa foi, então, contrapor outro paradigma (não dualista) de informação, através da abordagem sistêmica, embasada nos autores Humberto Maturana, Francisco Varela, e para o fenômeno da informação Niklas Luhmann. Deste último autor, retiramos a concepção central da informação como diferenças que produzem mudanças sistêmicas, organizando-se como sistemas psíquicos ou sociais. Essa noção central foi aprofundada, a partir da ideia que a informação se organiza como regimes de aceitação de diferenças em cada um desses sistemas. Para os sistemas psíquicos, baseamo-nos em Giulio Tononi, para quem o emaranhamento entre complexos de informação integrada (criando regimes expansivos) permite a emergência de conceitos. À medida que esse regime permite a emergência de sistemas de consciência que regulam o foco sobre esses conceitos, sugerimos - baseados na abordagem ecológica dos conceitos de Liane Gabora, Eleonor Rosch e Diederik Aerts - que ele, então, passa a ser complementado por outro, redutivo, que abstrai e desvincula os conceitos de seus contextos imediatos, permitindo a imaginação. Esse corpo teórico foi então confrontado com os dilemas teóricos levantados na literatura do Corpus - composto por artigos que tratassem dos processos de categorização ou aspectos cognitivos da teoria dos conceitos em Ciência da Informação. Constatamos que, em CI, a questão da formação dos conceitos confirmava a hipótese: a área de organização do conhecimento opta por uma visão cognitivista e dualista em que os conceitos se formam a partir de um núcleo de representações invariáveis (de natureza perceptiva) e os aspectos contextuais ficam restritos a operações periféricas de identificação. Concluímos que o paradigma representacionista é, em geral, dominante e que a área de organização da informação e conhecimento (e também a CI) deveria se abrir para outras abordagens, e propusemos como uma alternativa a abordagem sistêmica da informação, que apresentamos nesta pesquisa.The theories about the formation of concepts in Information Science (IS) lack of a deeper approach on this discipline\'s main object: information. This research carries out a reflection on this lack adopting the strategy of considering the issues of information definition and concept as interdependent. This strategy defines this issue while phenomenon (how information interacts with the formation of concepts?), avoiding the departure from several exercises to try to define these concepts. Therefore, this research\'s objective is guided by the comprehension of that phenomenon in the key-dominions where information and concepts unfold and complete each other: the cognitive, the social and the communicational ones. However, this comprehension requires a differentiated approach for the issue of information, in which it participates of this dominions organization process, thus leaving the traditional perspective of information as communicative occurrences or event effects on mind. This thesis\' hypothesis was that this traditional and generalist perspective of information generates a cognitivist comprehension of formation of concepts, supported by a dualist paradigm of cognition under the dichotomy objective/subjective. This research\'s objective was to offer another (non-dualist) paradigm of information through the systemic approach based on the authors Humberto Maturana, Francisco Varela and, for the information phenomenon, Niklas Luhmann. From this last author, we took the core conception of information as differences that produce systemic changes, auto-organizing themselves as psychic or social systems. This core notion was deepened with the idea that information organizes itself as regimes of differences acceptation in each of these systems. For the psychic systems, we used Giulio Tononi, for whom the tangling between complexes of integrated information (creating expansive regimes) allows the emergence of concepts. As this regime allows the emergence of conscience systems that rule the focus on these concepts, we suggest - based on the ecological approach of Liane Gabora, Eleonor Rosch and Diederik Aerts - that it is, now, complemented by other, reductive, that abstracts and detaches the the concepts from its immediate concepts, acknowledging imagination. This theoretical body was, then, confronted with the theoretical dilemma in the gather of Corpus literature - composed by articles that tackled the processes of categorization or cognitive aspects of concepts theory in Information Theory. We verified that, in IS, the issue of formation of concepts confirmed the cognitivist hypothesis: the area of knowledge organization chose the cognitivist and dualist vision in which concepts are formed by a nucleus of invariable representations (of perceptive nature) and the contextual aspects are restricted to peripheral identification. We concluded that the representational paradigm is, in general, hegemonic and that the areas of information and knowledge organization (and also IS) should open to other approaches, proposing the systemic approach of information as an alternative, which is presented in this research

Denna uppsats har skapats för att agera underlag vid framtagandet av en strukturskiss över fastigheten Nya Jägersro i Malmö. Uppsatsen syftar till att skapa ett planeringskoncept som kombinerar social och ekologisk hållbarhet genom att ta hänsyn till platsens specifika egenskaper. Både kommunen och fastighetsägaren, de två mest inflytelserika aktörerna för fastigheten, lägger stort fokus på hållbar utveckling. Uppsatsens frågeställningar baseras i två problematiker. Den första är fastighetsägarens separation av hållbarhetsaspekter som genom resonemanget om att hållbarhet skapas genom interaktioner mellan hållbarhetsaspekter kan bli problematisk. Den andra är hur Nya Jägersro som plats påverkas av ideal om förtätning i syfte att bygga hållbart. För att adressera dessa problem är uppsatsens syfte att ta fram ett planeringskoncept som kombinerar social och ekologisk hållbarhet och som tar hänsyn till platsens specifika egenskaper. Det teoretiska ramverket består av tre teorier som behandlar hållbar platsspecifik planering och design för att utveckla hållbara städer. De metoder av datainsamling som har använts är platsläsning, litteraturstudier och semistrukturerade intervjuer. Planeringskonceptet som slutligen presenteras benämns som JägersGro, vilket sammanfaller i flera avseenden med SMT:s och Malmö Stads agendor, men avviker delvis i vissa aspekter. Den största avvikande faktorn i relation till SMT är att JägersGro utgår från att hållbarhet utgörs av kombinationen mellan olika hållbarhetssystem. Ytterligare en avvikande faktor från båda aktörerna är att JägersGro förespråkar idén om att människans påverkan på de naturliga systemen inte enbart bör reduceras. Istället anses hållbara stadsdelar behöva vara med i återskapande processer för att kunna fungera i ett balanserat kretslopp med naturen.This thesis has been created to act as a basis for the preparation of a structural sketch of the property Nya Jägersro in Malmö. The thesis aims to create a planning concept that combines social and ecological sustainability by taking into account the specific characteristics of the site. Both the municipality and the property owner, the two most influential stakeholders, place great focus on sustainable development. The thesis examines two problems. The first is the property owner's separation of sustainability aspects, which through the reasoning that sustainability is created through interactions between different sustainability aspects can become problematic. The second is how Nya Jägersro as a place is affected by ideals of densification in order to build sustainably. To address these problems the purpose of the thesis is to develop a planning concept that combines social and ecological sustainability by taking into account the specific characteristics of the site. The theoretical framework consists of three theories that deal with sustainable site-specific planning and design for developing sustainable cities. The methods of data collection that have been used are site reading, literature studies and semi-structured interviews. The planning concept that is finally presented is referred to as JägersGro, which coincides in several respects with SMT's and Malmö Stad's agendas, but also deviates in some aspects. The biggest deviating factor in relation to SMT is that JägersGro assumes that sustainability consists of the combination of different sustainability systems. Another deviating factor from both actors is that JägersGro advocates the idea that the human impact on the natural systems should not only be reduced. Instead, sustainable districts are considered to be involved in regenerative processes in order to function in a balanced cycle with nature.

The expansion of Interstate 26 from Erwin, TN to the North Carolina border was a project that potentially adversely impacted South Indian Creek because of the steep landscapes and potential for erosion. Several studies have shown the short-term, negative effects of road construction on the water quality of nearby water bodies. Non-point source pollution is the major source of water pollution in the United States. The primary objective of this research is to evaluate the long-term effects of the construction of Interstate 26 on South Indian Creek to see if there has been any ecological recovery. The Environmental Health Sciences Laboratory of East Tennessee State University was contracted by the Tennessee Department of Transportation to collect data from before construction (1991-1992), during construction (1993-1994), and postconstruction (1995-1996). Comparison of microbial enzyme activities and other parameters to present-day (2012-2013) water quality conditions indicate that South Indian Creek has not fully recovered from the effects of the construction of the interstate.

Human societies are reliant on the functioning of the hydrologic cycle. The atmospheric branch of this cycle, often referred to as moisture recycling in the context of land-to-land exchange, refers to water evaporating, traveling through the atmosphere, and falling out as precipitation. Similar to the surface water cycle that uses the watershed as the unit of analysis, it is also possible to consider a ‘watershed of the sky’ for the atmospheric water cycle. Thus, I explore the precipitationshed - defined as the upwind surface of the Earth that provides evaporation that later falls as precipitation in a specific place. The primary contributions of this dissertation are to (a) introduce the precipitationshed concept, (b) provide a quantitative basis for the study of the precipitationshed, and (c) demonstrate its use in the fields of hydrometeorology, land-use change, social-ecological systems, ecosystem services, and environmental governance. In Paper I, the concept of the precipitationshed is introduced and explored for the first time. The quantification of precipitationshed variability is described in Paper II, and the key finding is that the precipitationsheds for multiple regions are persistent in time and space. Moisture recycling is further described as an ecosystem service in Paper III, to integrate the concept into the existing language of environmental sustainability and management. That is, I identify regions where vegetation more strongly regulates the provision of atmospheric water, as well as the regions that more strongly benefit from this regulation. In Paper IV, the precipitationshed is further explored through the lens of urban reliance on moisture recycling. Using a novel method, I quantify the vulnerability of urban areas to social-ecological changes within their precipitationsheds. In Paper V, I argue that successful moisture recycling governance will require flexible, transboundary institutions that are capable of operating within complex social-ecological systems. I conclude that, in the future, the precipitationshed can be a key tool in addressing the complexity of social-ecological systems.At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 4: Manuscript. Paper 5: Manuscript.

The approach adopted in this thesis is essentially chronological. The first chapter aims to provide a fairly superficial survey of the development of European perceptions of the environment in the early phases of mercantilist expansion, before much in the way of colonial settlement was undertaken. It highlights the connections between expansion and changes in perception with regard to the symbolic importance of islands, botanic gardens and early state responses to timber shortage. It also draws attention to the importance of medical perceptions of the extra-European environment. In the second chapter a comparison is drawn between Dutch and English approaches to the tropical environment in the early years of expansion. Considerable space is devoted to the case of St Helena. This is because it was the first location in which European colonists first acquired a notion of the full environmental implications of their rule and for which detailed documentary evidence is available. The story of the developing ecological crisis on St Helena emphasises how inadequate European precedents were in the encounter between the early colonial state and the tropical environment. It demonstrates, too, the early divergence in perceptions between colonists and the metropolitan power. Early attempts at counteracting the process of ecological deterioration on St Helena underlined the contradictions between the European image of the tropical island and the reality of capital investment in plantation agriculture and 'improvement'. The experience of St Helena was also important in a longer-term way. Many scientists important in the later development of conservation ideas in other parts of the world were specifically influenced by their knowledge of the problematic history of land-use on St Helena and the attempts made there to impede ecological degradation. These included Alexander Beatson, J.R. Forster, Joseph Hooker, F.A. Dalzell and G.P. Marsh. In the third chapter much attention is devoted to the history of eighteenth century Mauritius, partly for comparative purposes and partly to emphasise the attitude of the French state to scientific information and its greater readiness to intervene in environmental matters. The development of an environmental consciousness on Mauritius was significant both as a phenomenon on its own and because of the example which it set. The role of the colonial government naturalist was pioneered there. Concepts of species extinction also emerged clearly, for the first time, on Mauritius and the island also saw the emergence of a legislative conservation policy rooted in a desiccation theory which linked deforestation and soil erosion to hydrological and climatic conditions. Notions of environmental moral economy and the significance of the tropical island are also explored in the chapter, in the context of the emergence of pre-Revolutionary radicalism, Physiocracy and early Romantic thinking. Chapter Four attempts to deal in some depth with the intellectual background to the early nineteenth century response of the British to ecological change in India. The importance of German science and a German 'romanticist' critique of ecological change is outlined and some emphasis is given to the emergence of a 'global' approach to the interactions between people (especially Europeans) and the environment. In particular the significance of the intellectual links between the Cook Voyages and the careers of J.R. Forster, Sir Joseph Banks and Alexander Von Humboldt is stressed. A beginning is also made in the task of surveying the way in which German professional naturalists and doctors deliberately sought out British colonial employ, a phenomenon that was to be important in the emergence of state conservation in India, the Cape, Australia and in other colonies. The chapter makes clear the continuing importance of small island environments during the nineteenth century in stimulating an awareness of environmental vulnerability, particularly for Alexander Beatson, William Burchell and J.B. Boussingault.

Pesquisas em que se procura investigar a relação entre os fatores ambientais e o comportamento dos consumidores são ainda embrionárias no Brasil, o que constitui uma oportunidade para estudos que relacionam o comportamento de compra dos consumidores com as questões ambientais. Nessa perspectiva, o objetivo da presente pesquisa foi verificar se existe correlação entre os construtos: conhecimento ecológico, afeto ecológico, preocupação ecológica, normas subjetivas e o comportamento de compras verdes. Na busca do alcance dos objetivos propostos, adotou-se uma metodologia caracterizada pela pesquisa exploratória, utilizando-se o método transversal simples no processo de coleta dos dados. Foram adotados no estudo dados secundários, provenientes de artigos, livros, dissertações, teses e internet, além de dados primários, coletados com a aplicação de questionários à população-alvo. Partindo-se de uma amostragem aleatória estratificada, essa população foi constituída pelas mulheres acima dos 18 anos, por representarem consumidoras potenciais de produtos cosméticos. No tratamento dos dados dos 500 questionários validados, contemplouse a utilização do coeficiente Alpha de Cronbach e da técnica multivariada de análise fatorial exploratória. Um modelo de regressão múltipla foi testado para explicar o comportamento de compra de cosméticos ecológicos. Os resultados deixam evidências de que as variáveis Normas Subjetivas (NS), Afeto Ecológico (AE), Preocupação Ecológica (PE) e Conhecimento Ecológico (CE) foram consideradas estatisticamente significantes para explicar as variações em Comportamento de Compra de Cosméticos Ecológicos (CCCE), com um R2 de 0,555. Entre as variáveis demográficas testadas, verificou-se que apenas a faixa etária e a classe social exercem influência moderada sobre a variável dependente. Tais resultados sinalizam similaridade entre os resultados obtidos na mensuração da correlação múltipla entre as variáveis independentes, a variável dependente e aqueles observados na teoria sobre a influência da primeira sobre o comportamento de compra de produtos ambientalmente corretos. Os resultados desta tese oferecem uma compreensão adicional sobre os fatores que afetam o processo de decisão de compra do consumidor. Considera-se, portanto, que este trabalho constitui um avanço no estado da arte das pesquisas sobre a relação entre os fatores ambientais e o comportamento dos consumidores, uma vez que foram investigados aspectos não contemplados em estudos anteriores.Research which seeks to investigate the relationship between environmental factors and the consumer behavior is still embryonic in Brazil, which is a unique opportunity for those studies that relate the purchasing behavior of consumers to environmental issues. In this perspective, the goal of this research was to ascertain whether there is correlation between the following constructs: ecological knowledge, ecological affection, ecological concern, subjective norms and green purchase behavior. In pursuit of achieving the proposed objectives, a methodology characterized by exploratory search was used, adopting the simple transverse method in data collection process. In the study, secondary data from articles, books, dissertations, theses and the internet were used, in addition to the primary data, collected with the application of questionnaires to the target population. Based on a stratified random sampling, the population was constituted by women over 18 years old, since they represent potential consumers of cosmetic products. Regarding the data processing of 500 validated questionnaires, the use of Cronbach\'s Coefficient Alpha and multivariate exploratory technique of factor analysis were contemplated. A multiple regression model was tested to explain the behavior of buying ecological cosmetics. The results produce evidence that Subjective Norms (SN), Ecological Affection (EA), Ecological Concern (EC) and Ecological Knowledge (EC) variables were considered statistically significant to explain the variations in Purchase Behavior of Ecological Cosmetics (PBEC), with an R2 of 0.555. Among the demographic variables tested, it was found that only the age and social class exercise moderate influence over the dependent variable. Such results indicate similarity among the results obtained in the measurement of multiple correlations among independent variables, the dependent variable and those observed in theory concerning the influence of the former over the purchasing behavior of environmentally correct products. The results of this thesis offer additional insight about the factors that affect the purchase decision process. Therefore, it is considered that this work is an advance in the state of the art of research about the relationship between environmental factors and the consumer behavior, since aspects not covered in previous studies were investigated.

The ecological design considerations are focusing on the built environment and the living process of the building. It considering the environment impact in designing building, and integrating ecological responsive design methods. While the traditional Chinese building shared the same design philosophy. Our ancestors are really concerning the connection between their living space with the broader environment, not only in the time they occupying the building, but also when they construct and demolish it. They use the word "harmony" to describe this relationship with the environment, and consider it as the high-quality pursuit of life. Wooden building has been a major building type in China for thousands of years, however, over 40 thousand traditional Chinese building has been demolished in the past 30 years, most of them are wooden buildings. Since the steel, concrete and other emerging materials has become the major materials for the modern building, wooden building seems to step down from the stage of history. Not until in recent years, wooden building come into people’s view again, it’s increasingly appeared in all over the world and take part in a major role in mordent architecture. Since the wood is a sustainable and renewable building material, and a good carbon sink, it is more environmental friendly than steel, concrete or some other building materials. The wooden building has a great potential to discover its ecological benefits and as a carrier of traditional Chinese culture. In seeking the development of wood as a building material, and the future of sustainable buildings, I integrate the theory with practice that human population is growing rapidly, the high-rise wooden building might be a best solution for this quest. I expect to explore the application of wood in high rise building’s envelope and structure, integrate the wood with other material to expand its performance, emotionally and reality connect the traditional Chinese culture and people’s memory of the land to the present day.

Förekomsten av vattenrelaterade problem som extrem nederbörd, översvämningar, torka och vattenbrist kommer att öka i urbana områden till följd av de globala klimatförändringarna. Sponge city-konceptet är ett urbant dagvattenhanteringssystem som lanserades i Kina och syftar till att förbättra vattenhanteringen i städer genom att återställa stadens kapacitet att absorbera, infiltrera, lagra och rena vatten. Den här studien syftade till att undersöka om sponge city-konceptet hade kunnat implementeras i Malmö genom att besvara frågeställningen ” Vilka möjligheter respektive hinder finns det för Malmö att implementera sponge city-konceptet?”. Genom en systematisk litteraturstudie och innehållsanalys i kombination med det teoretiska ramverket som baserades på konceptet sårbarhet för klimatförändringar visade resultatet på att det både finns en del möjligheter men också hinder. Det huvudsakliga hindret som identifierades är att en stor del av marken i Malmö består av täta moränleror vilket utgör ett hinder för de infiltrationsåtgärder som ingår i sponge city-konceptet. Några möjligheter som identifierades är att sponge city-konceptet kan minska känsligheten för skada som uppstår i förhållande till exponeringsnivån, samt att Malmös anpassningskapacitet är relativt hög. På grund av att den här studien enbart undersökte specifika fysiska/miljömässiga aspekter inom sponge city-konceptet krävs däremot fler studier som tar hänsyn till fler aspekter om en implementering av konceptet skulle bli aktuell.The occurrence of water related problems such as extreme precipitation, floods, drought and water scarcity will increase in urban areas as a result of global climate change. The sponge city-concept is an urban stormwater system launched in China and aims to improve the water management in cities by restoring the city’s capacity to absorb, infiltrate, store and purify water. This study aimed to investigate if the sponge city-concept could be implemented in Malmö by answering the question “What possibilities and obstacles exist for Malmö to implement the sponge city-concept?”. Through a systematic literature review and content analysis in combination with the theoretical framework, which was based on the concept climate change vulnerability, the results showed that there are some possibilities but also obstacles. The main obstacle that was identified is that the ground in Malmö largely consists of dense moraines which forms an obstacle for the infiltration measures that are included in the sponge city-concept. Some possibilities that were identified is that the sponge city-concept can decrease the sensitivity to harm that occurs in relation to the exposure level but also that Malmö’s adaptation capacity is relatively high. However, because this study only investigated specific physical/environmental aspects within the sponge city-concept, more studies that consider more aspects are required if an implementation of the concept would become prevailing.

Mestrado em Planeamento do Território - Ordenamento da CidadeA industrialização originou problemas sócio-ambientais na cidade. Assim, durante o século XIX e XX, o pensamento urbanístico criou soluçõeshigienistas com a ideia de configurar um modelo urbano. A partir dos anos 60do século XX e devido às grandes alterações sofridas até então,intensificaram-se as preocupações ambientais e, na procura de um modeloalternativo, surgiu a ideia de desenvolvimento sustentável. Perante a crescenteconsciencialização acerca das alterações climáticas e dos problemasambientais, as preocupações ecológicas ganham realce e a ecologia urbanatorna-se alvo de conhecimento e abordagem em várias disciplinas,nomeadamente no desenho físico das estruturas urbanas. Na procura de um urbanismo como resposta a um desenvolvimentosustentável à escala local, durante os anos 90 do século XX surge o ecobairro,como projecto-piloto de resposta na prática às preocupações e pensamentodesenvolvido até então. Os países do norte da Europa são pioneiros na suaconcretização. É assim que o ecobairro se configura, neste texto, como um caso de estudo emarco de referência para o bom desenho urbano em resposta àsustentabilidade ambiental. A partir deste e dos elementos retirados da História e da ecologia urbana, formulam-se princípios orientadores para o bom desenho urbano, que, após confronto com as formas urbanas, são reflectidosnum modelo operativo. ABSTRACT: Industrialization originated new socio-environmental problems in the city. Thus, during the XIXth and XXthcenturies, urban thinking devised hygienist solutions with the idea of configuring an urban model. From the 1960s onwards, due to the enormous changes, there was a growth of environmental concerns and,searching an alternate model, the birth of the idea of sustainable development.In the face of growing awareness about climate changes and environmentalproblems, ecological concerns came to the forefront and urban ecology became an area of interest and approach through various disciplines, includingthe physical design of urban structures. In search of an urbanism of response to sustainable development at a locallevel, during the 1990s, eco-neighborhood comes to life as a pilot project of practical response to the concerns and thought developed till then. NorthernEuropean countries are pioneers in its making. Thus, eco-neighborhoods are analyzed, in this text, both as case studies and as historical references for good urban design in answer to environmentalsustainability. With this analysis and elements drawn from history and urbanecology, we present guiding principles for good urban design that, after aconfrontation with urban forms, are reflected in an operative model.

O objetivo desta pesquisa é apresentar um estudo, sob o ponto de vista histórico, sobre as ideias do botânico e taxonomista americano Henry Allan Gleason (1882-1975) referentes ao conceito individualístico de associação de plantas. Nas décadas iniciais do século XX, as ideias do ecólogo americano Frederic Edward Clements (1874-1945) sobre a dinâmica da vegetação e sobre sucessão ecológica eram prevalecentes. Porém, a discordância dessas ideias parece ter levado Gleason a propor inicialmente o conceito individualístico da ecologia e, posteriormente, o conceito individualístico de associação de plantas. O desenvolvimento do conceito individualístico proposto por Gleason pode ser analisado, principalmente, por meio de suas obras dos anos de 1917, 1926 e 1939. Além dessas, nas quais Gleason refere-se especificamente ao conceito individualístico, outras obras estão sendo consideradas, como seu artigo publicado no ano de 1909, no qual discutiu sobre algumas questões fitogeográficas e ecológicas que influenciariam a distribuição de pradarias e florestas; seu artigo publicado em 1910, no qual apresentou o primeiro indício da sua visão individualística, e seu artigo publicado em 1927, no qual ele discorreu sobre os processos de sucessão em diferentes locais. A partir da análise de obras originais de Gleason e Clements, bem como mediante os relatos das fontes secundárias considerando o contexto da época, procurar-se-á evidências que mostrem o entendimento de Gleason sobre os estudos ecológicos e suas contribuições ao arcabouço teórico da Ecologia.The objective of this research was to study, from a historical perspective on the ideas of botanist and taxonomist American Henry Allan Gleason (1882-1975) for the individualistic concept of plant association. In the early decades of the twentieth century, the American ecologist ideas Frederic Clements (1874-1945) on the dynamics of vegetation and on ecological succession were prevalent. However, the disagreement of those ideas seems to have taken Gleason initially proposing the individualistic concept of ecology and subsequently the individualistic concept of plant association. The development of the individualistic concept proposed by Gleason can be analyzed primarily through his works of the years 1917, 1926 and 1939. In addition to these, in which Gleason refers specifically to the individualistic concept, other projects are being considered, as its Article published in 1909, which discussed some phytogeographic and ecological issues that influence the distribution of grasslands and forests; Article published in 1910, which presented the first evidence of its individualistic vision, and his article published in 1927 in which he talked about the succession processes in different locations. From the analysis of original works of Gleason and Clements, as well as by reports of secondary sources considering the context of the time, it will be sought evidence to show understanding of Gleason on the ecological studies and their contributions to the theoretical framework of Ecology.

This dissertation is a comparative international study of attitudes towards climate change. Using multilevel models, individual level data from the 2005-2008 wave of the World Values Survey, and country level data from the 2010 Climate Risk Index and the World Bank, this research identifies the factors associated with concern for global warming and support for various environmental policies and behaviors in economically developed, transitioning, and developing countries. The first paper addresses an ongoing debate in environmental sociology about the extent to which concern for environmental problems is a result of the objective deterioration of environmental conditions or subjective values among environmentally-oriented individuals. Findings indicate that a country's recent experience with climate-related environmental disasters has little to no effect on concern for global warming. Some support is found for the subjective values explanation, especially in countries at the most advanced stage of economic development. The second paper frames climate change as an asymmetrical social dilemma and tests whether four distinct citizenship identities are associated with the odds an individual considers global warming a very serious problem. This study finds that identifying as world citizens and autonomous individuals increases the odds an individual judges global warming very serious, while identifying as national citizens or local community members has no relationship with evaluations of global warming. The third paper examines the impact of numerous measures of security/vulnerability on individual willingness to make environment-economy trade-offs. The data reveal that higher household incomes, residing in a country with higher per capita GDP, and higher rates of adult literacy are positively associated with prioritizing environmental protection over economic growth. However, residents of economically developing countries (or countries designated Non-Annex I by the Kyoto Protocol) are also much more likely to express willingness to donate personal income for the protection of the environment compared to residents of developed (Annex I) countries. The findings from these three studies have implications for sociological research on the relationship between economic inequality and environmental attitudes, the conditions under which international cooperation on climate is more or less likely, and the quest for climate justice.

Recent technological advances facilitating the acquisition of spatial observational data and an increasing awareness of issues of spatial pattern and scale have fostered the development and use of statistical methods for multi-scale analysis. These methods can be interesting tools to improve our understanding of natural systems, but their use must be guided by a good comprehension of the statistics and their assumptions. This thesis is an effort to develop a coherent framework for multi-scale analysis and to identify theoretical, statistical and practical issues and solutions. After defining terminology and concepts, several methods are compared using a common dataset in Chapter 2. The geostatistical method of regionalized multivariate analysis is identified as possessing several advantages, but shortcomings are identified, discussed and addressed in two manuscripts. In the first one (Chapter 3), a mathematical formalism is presented to characterize the spatial uncertainty of cokriged regionalized components and an approach is proposed for the conditional Gaussian co-simulation of regionalized components. In the second manuscript (Chapter 4), the theory underlying coregionalization analysis is discussed and its robustness and limits are assessed through a theoretical and mathematical framework. The assumptions underlying the method and the high levels of uncertainty associated with its use highlight problems with the interpretation of results, and issues with the application of probabilistic models in a spatial context (Chapter 5). Coregionalization analysis with a drift (CRAD), presented in detail in two co-authored publications, is proposed as a sensible alternativeDes avancées technologiques récentes facilitant l'acquisition de données observationnelles spatiales, et la conscientisation grandissante des chercheurs aux problèmes d'échelles, ont favorisé le développement et l'utilisation de méthodes statistiques d'analyse multi-échelles. Ces méthodes peuvent être des outils intéressants pour améliorer notre compréhension des écosystèmes, mais leur usage nécessite une bonne connaissance des théories statistiques et des hypothèses qui leur sont sous-jacentes. Cette thèse a pour but de contribuer au développement d'un cadre conceptuel cohérent pour l'analyse multi-échelles en identifiant des problématiques et des solutions théoriques, statistiques et pratiques. La terminologie et les concepts appropriés sont d'abord définis. Ensuite, dans le chapitre 2, plusieurs méthodes sont comparées en utilisant un jeu de données commun. La méthode géostatistique d'analyse multivariable régionalisée semble offrir plusieurs avantages, mais certains problèmes sont identifiés, discutés et traités dans deux articles publiés. Le premier (chapitre 3) présente un formalisme mathématique servant à caractériser l'incertitude spatiale des composantes régionalisées cokrigées et propose une approche pour la co-simulation conditionnelle Gaussienne de composantes régionalisées. Dans le deuxième article (chapitre 4), l'analyse de corégionalisation est discutée et la robustesse ainsi que les limites de cette méthode sont évaluées selon une analyse théorique et mathématique. Les postulats de cette méthode et le haut niveau d'incertitude lié à son utilisation mettent en évidence des problèmes associés

Philosophiae Doctor - PhDThe increasing evidence of chemicals of emerging concern (CECs) in water bodies is causing major concern around the world because of their toxicological effects upon humans and aquatic organisms. The release of wastewater to the aquatic environment is most likely to introduce some trace levels of organic contaminants, some of which may be toxic, carcinogenic, or endocrine disruptors, as well as, persistent in the environment. These compounds are often persistent but not regularly monitored because they are mostly still excluded from environmental legislation. Their fate and persistence in the environment are not well understood.
