Abstract:

The lack of analytical models that can accurately describe large-scale networked systems makes empirical experimentation indispensable for understanding complex behaviors. Research on network testbeds for testing network protocols and distributed services, including physical, emulated, and federated testbeds, has made steady progress. Although the success of these testbeds is undeniable, they fail to provide: 1) scalability, for handling large-scale networks with hundreds or thousands of hosts and routers organized in different scenarios, 2) flexibility, for testing new protocols or applications in diverse settings, and 3) inter-operability, for combining simulated and real network entities in experiments. This dissertation tackles these issues in three different dimensions. First, we present SVEET, a system that enables inter-operability between real and simulated hosts. In order to increase the scalability of networks under study, SVEET enables time-dilated synchronization between real hosts and the discrete-event simulator. Realistic TCP congestion control algorithms are implemented in the simulator to allow seamless interactions between real and simulated hosts. SVEET is validated via extensive experiments and its capabilities are assessed through case studies involving real applications. Second, we present PrimoGENI, a system that allows a distributed discrete-event simulator, running in real-time, to interact with real network entities in a federated environment. PrimoGENI greatly enhances the flexibility of network experiments, through which a great variety of network conditions can be reproduced to examine what-if questions. Furthermore, PrimoGENI performs resource management functions, on behalf of the user, for instantiating network experiments on shared infrastructures. Finally, to further increase the scalability of network testbeds to handle large-scale high-capacity networks, we present a novel symbiotic simulation approach. We present SymbioSim, a testbed for large-scale network experimentation where a high-performance simulation system closely cooperates with an emulation system in a mutually beneficial way. On the one hand, the simulation system benefits from incorporating the traffic metadata from real applications in the emulation system to reproduce the realistic traffic conditions. On the other hand, the emulation system benefits from receiving the continuous updates from the simulation system to calibrate the traffic between real applications. Specific techniques that support the symbiotic approach include: 1) a model downscaling scheme that can significantly reduce the complexity of the large-scale simulation model, resulting in an efficient emulation system for modulating the high-capacity network traffic between real applications; 2) a queuing network model for the downscaled emulation system to accurately represent the network effects of the simulated traffic; and 3) techniques for reducing the synchronization overhead between the simulation and emulation systems.

Abstract:

This report focuses on governance mechanisms for industrial symbiosis (IS). The study takes an organizational approach on material and energy exchanges between different organizations (or different parts in the same organization) leading to increased regional resource efficiency. This project explores different strategies for governance mechanisms and analyzes how these affect trust. Significant factors for initiating and keeping a collaboration successful are also analyzed. Representatives from 24 Swedish cases of symbiotic arrangements are interviewed and ten themes affecting IS collaborations are identified. The themes are governance structure, shared vision, previous collaboration, local conditions, initiating a collaboration, activities to build trust, conflicts, transaction-based or goal-oriented approach, indicators and distribution of costs and benefits. Among the governance structures used are hierarchy (collaboration between different parts of the same organization), joint venture, strategic alliance and different types of agreements. Common is a 10-15 years agreement, sometimes combined with a strategic discussion about the development of the collaboration. Three factors particularly affecting collaborations are identified: strategic meetings, indicators related to the collaboration and fair profit distribution. The factor strategic meetings is about combining long term agreements with innovation. Long term agreements might be necessary when a project requires investments. Meanwhile, this can suppress innovation by supporting outdated solutions. The paradox of needing both long term agreements and continued innovation may be solved by the practice of having strategic meetings and contract surveillance. Another significant factor for successful collaborations is the use of jointly evaluated indicators. To jointly evaluate a project according to predetermined indicators gives all parties the opportunity to know when a collaboration is successful. The third significant factor is fair profit distribution. Unfair profit distribution may delay or stop a project. It may also decrease trust in an ongoing project. A fair profit distribution is a key factor for enabling long term relationships.
Den här rapporten studerar samarbetsformer för industriell symbios (IS). Fokus för den här studien är material- och energiutbyten mellan organisationer eller mellan olika delar i samma organisation som leder till regional resurseffektivisering. Val och implementering av samarbetsform analyseras i relation till förtroende mellan organisationer och lyckade samarbeten. Viktiga faktorer för att lyckas starta och bibehålla ett symbiossamarbete analyseras också. Representanter från 24 svenska fall av symbiotiska samarbeten intervjuas och deras svar analyseras utifrån tio teman: samarbetsform, gemensam vision, tidigare samarbete, lokala förutsättningar, att starta ett samarbete, aktiviteter för att bygga förtroende, konflikter, transaktionsbaserat eller målinriktat förhållningssätt, indikatorer och vinstfördelning. Bland de samarbetsformer som används återfinns hierarki (samarbete mellan olika delar i samma organisation), joint venture, strategisk allians och olika typer av avtal. Vanligt är avtal på 10-15 år, ibland kombinerat med en strategisk diskussion om samarbetets utveckling. Tre faktorer identifieras som extra viktiga vid symbiotiska samarbeten: strategiska möten, indikatorer relaterade till samarbetet och rättvis vinstfördelning. Strategiska möten handlar om att kombinera långsiktiga avtal med innovation. Långsiktiga avtal behövs ofta i symbiossamarbeten för att kunna göra investeringar. Samtidigt kan detta låsa fast utdaterade lösningar och försvåra innovation och utveckling. Att ha avtalsbevakning och en strategisk diskussion kring utveckling av samarbetet har identifierats som ett sätt att lösa detta på. En annan betydande faktor för lyckade samarbeten är gemensamma indikatorer relaterade till samarbetet. Att gemensamt utvärdera samarbetet enligt uppsatta indikatorer ger alla parter möjlighet att veta när ett samarbete lyckats. Den tredje identifierade faktorn är rättvis vinstfördelning. Orättvis vinstfördelning kan stoppa eller försena ett samarbete. Det kan också urholka parternas förtroende till varandra. En rättvis vinstfördelning kan däremot skapa förtroende och är en nyckelfaktor till ett långsiktigt samarbete.

Abstract:

In this paper, I explore the emerging field of voluntary implants as seen in the DIY biohacking scene. My work on such implants focuses specifically on implantable Radio frequency Identification capsules. With the approach of research through design, I have undergone an iterative process, combining research and prototyping methods to externalize insights and knowledge generated along the way, in an effort to bring shed light on the new ideas and design considerations that arise when we embed computer technology in our bodies. By challenging the status quo, and setting aside my preconceptions through speculative design, my work has resulted in a working prototype, inspired by the ideology of slow technology. Elmer, the memory machine, is a device that enables the implantee to capture memories in point of time via their implants. Here user are can record and review moments of everyday life, merely through a timestamp — a design decision that contributes to the debate on topics like convenience, privacy, and the right to be human.

Abstract:

The occurrence in Scotland of arbuscular mycorrhizal fungi (AMF) infective on Alnus glutinosa and the effects on early growth of inoculation of seedlings with AMF and Frankia were investigated. AMF characteristic of G/omiw-like fungi were detected microscopically in A. glutinosa roots from mineral and loam but not from highly organic soils. Both GJomus- and Gigaspora-like fungi were detected only in roots from sandy soils. Glasshouse experiments showed that Glomus and Gigaspora species gave higher colonisation of roots, and were of higher compatibility with the host plant, than Acutelospora or Scutettospora species. Colonisation by AMF increased nodulation by Frankia and vice versa. Inoculation with AMF alone and dual inoculation with Gigaspora rosea and Frankia inhibited growth of young A. glutinosa seedlings. Initially after inoculation, AMF colonisation was poor allowing the host to meet the requirements of both developing symbioses. Mycorrhizal plants inoculated with Frankia 15 days after AMF inoculation, were under significant stress and this delayed the beneficial effects of AMF and Frankia symbiosis. Seedlings compensated for the cost of symbiosis by developing a larger, leafy shoot in a period of 25-30 days after AMF inoculation, with or with out, Frankia nodulation. A significant increase in root length and branching detected after inoculation with AMF and Frankia must impose additional energy requirements. However, the stimulation of lateral root branching that follows AMF colonisation may facilitate nutrient uptake, thus helping the plant to overcome the disadvantages of early retardation of shoot growth. Competition with adjacent plant species for below ground space may also be enhanced thus facilitating competition for growing space with other plant species. These factors may be part of a strategy that assists the survival of very young seedlings in the field. The data obtained suggest that delaying Frankia inoculation for 3-4 weeks after inoculation with selected AMF should improve the production in Scottish nurseries of robust, well nodulated and mycorrhizal seedlings.

Abstract:

In this study the natural science definition of symbiosis is modified in several ways to suit the business context. To demonstrate symbiosis it has been deemed appropriate that the SMEs must have noted, acted on and benefited from the changes being made by the main manufacturer/assembler. In this way it can be argued that the parties (the main manufacturer and its subcontractors) are in a symbiotic relationship. In order to test out the relevance and the academic viability of the symbiotic concept, it was felt that the study of a high-technology industry, for example aerospace, automotive or electronics, would be appropriate. With this factor in mind, the aerospace industry was selected as it is perceived to be globally oriented, have transitory customers, demands high-technology and quality assurance, appreciable percentage of out-sourcing and consists of a limited number of major manufacturers, each of whom are easily identifiable. BAe Prestwick (Prestwick) is a complete assembler of two aircraft models - the nineteen passenger Jetstream 31 and the twenty-nine passenger Jetstream 41. Prestwick routinely out-sources about sixty per cent of their components and sub-assemblies. The main issues discussed with the SMEs were whether they observed changes at Prestwick, to what extent were the SMEs making consequential mirror-image or similar changes, and finally, did the SMEs perceive the changes made by both parties as being mutually beneficial and commensal. The results established that there was growing symbiotic relationship occurring between the major manufacturer and thirty-four of its component suppliers who were studied in this research. These symbiotic changes meet the definition of symbiosis, mutual beneficiality and commensality as defined in this research. This case study therefore has justified the use of the symbiotic concept, modified for business purposes, as a useful tool for examining and analyzing the changing relationships between the major assembler and a sample of subcontractors in the civil aerospace industry.

Abstract:

This thesis sets out a model to examine how the internet functions. 'The symbiotic web' suggests a symbiotic relationship between corporations that have built business models dependent upon the gathering of personal data from people, and the individuals themselves who have begun to rely on apparently 'free' services (from search to email, social networking to YouTube). Having set out the model, the thesis looks at its implications: how it has contributed to many, both the positive and negative, developments on the internet in recent years, but also driven the mass gathering, use and holding of personal data. The symbiotic web is currently essentially beneficial to both businesses and individuals, but there are significant risks attached - risks associated with the accumulation of data and risks that the symbiotic relationship could become negative and parasitic, putting individuals' privacy and autonomy at risk. The implications of this model are examined through the use of case studies: the dispute between Google and the Article 29 Working Party over data retention, Phorm's 'Webwise' behavioural targeting system, and a number of smaller case studies about data vulnerability from the HMRC data disc loss to the ACS:Law hack/leak. The thesis suggests the development and use of specific rights designed for the internet to address the associated risks: a 'right to roam the internet with privacy', a right to monitor those who monitor us, and a 'right to delete data'. These rights would be set out as principles rather than enacted and enforced as laws, and brought into play through Murray's model of symbiotic regulation. These rights would support the positive development of the web symbiosis and encourage and shape new business models that are more supportive of individual autonomy and privacy.

Nature offers a wide range of phenomena that inspire the development of new technologies. The researchers from the area of Natural Computing abstracts the concept of optimization from various biological processes such as the evolution of species, the behavior of social groups, the search for food, among others. Such computer systems that have a similarity to natural biological systems are called biologically plausible. The development of biologically plausible algorithms gets interesting by the fact that biological systems are able to handle extremely complex problems. In this way, symbiotic relationships are one of several phenomena that can be observed in nature. These relationships consist of interactions that organisms carry out with each other resulting in benefit or disadvantage to those involved. In an optimization context, symbiotic relationships can be used to perform exchange of information between populations of candidate solutions to a given problem. Thus, this work highlights the concepts involving symbiotic relationships that may be important for the development of computer systems to solve complex problems. The main discussion presented in this study refers to the use of symbiotic relationships between populations of candidate solutions co-evolving in an ecological context. According to the analogy, populations interact with each other according to a specific symbiotic relationship in order to evolve their solutions. The proposed model is applied to several continuous benchmark functions with a high number of dimensions (D = 200) and in several benchmark instances of the multiple knapsack problem. The results obtained so far were promising concerning the application of symbiotic relationships. Finally, the conclusions are presented and some future directions for research are suggested.
A Natureza apresenta uma grande variedade de fenômenos que inspiram o desenvolvimento de novas tecnologias. Os pesquisadores da área de Computação Natural abstraem o conceito de otimização de vários processos biológicos, tais como a evolução das espécies, comportamento de grupos sociais, busca por comida, dentre outros. Tais sistemas computacionais que apresentam uma semelhança com os sistemas biológicos naturais são chamados de biologicamente plausíveis. O desenvolvimento de algoritmos biologicamente plausíveis se torna interessante pelo fato de que os sistemas biológicos são capazes de lidar com problemas extremamente complexos. As relações simbióticas são um dos vários fenômenos que podem ser observados na natureza. Essas relações consistem de interações que organismos realizam entre si resultando em benefícios ou prejuízos para os envolvidos. Em um contexto de otimização, as relações simbióticas podem ser utilizadas para realizar a troca de informação entre populações de soluções candidatas para um dado problema. Desta forma, este trabalho destaca os conceitos que envolvem as relações simbióticas que podem ser importantes para o desenvolvimento de sistemas computacionais para a resolução de problemas complexos. A principal discussão apresentada nesse trabalho refere-se a utilização de relações simbióticas entre populações de soluções candidatas, coevoluindo em um contexto ecológico. Com essa analogia, cada população interage com uma outra de acordo com uma relação simbiótica específica, com o objetivo de evoluir suas soluções. O modelo apresentado é aplicado a várias funções benchmark contínuas com um número alto de dimensões (D = 200) e várias instâncias benchmark do problema da mochila múltipla. Os resultados obtidos se mostraram promissores considerando a aplicação das relações simbióticas. Por fim, as conclusões são apresentadas e algumas direções para pesquisas futuras são sugeridas.

Abstract:

The ecological success and also the susceptibility of corals to bleaching have been attributed to their obligate relationship with Symbiodinium and its functional diversity. Deeper understanding of this symbiosis is essential to enable the existence of reef ecosystems. This thesis aimed to determine how the environment and the host exert control over the proteome of Symbiodinium and how this is related to the maintenance of symbiosis. Firstly, it was explored how the proteome related to the photoacclimation strategies of Symbiodinium, and its regulation under different light environments. An initial assessment of the proteome regulation using shotgun proteomics over Symbiodinium type C1 cultured at two experimental photon fluxes displayed differences in proteins associated with light harvesting, electron transport, carbon fixation and protein modification. Subsequent two-dimensional gel electrophoresis (2-DE) analysis between three Symbiodinium types (A1, A13 and C1) cultured at the two previous photon fluxes revealed unique proteome differences across these types and between both experimental light treatments. Database searches of the isoelectric point (pI) and the molecular weight (MW) tagged these proteins also associated with the same processes matched by previous shotgun analysis over C1 type. These results are in agreement with previous hypothesis on different photoacclimation strategies displayed among different types of Symbiodinium. These strategies comprised differential proteomic modifications in the photosynthetic unit (PSU) of the experimental types of Symbiodinium to balance ATP production and achieve homeostasis at different photon flux environments. The host control effect and regulation of the proteome and physiology of Symbiodinium ex- hospite was studied using two host release factors (HRFs) a free aminoacid mix (FAA) and the host tissue (HT) homogenate from the coral Pocillopora damicornis. To comprehend the relation between the proteome and physiology various parameters related with the photosynthate production and translocation of Symbiodinium were measured including: glucose released, excitation pressure over photosystem two (PSII), total protein, total glucose and chlorophyll a concentration in the presence and absence of the HRFs. The measured parameters showed variability among types. In general, the parameters directly related to photochemistry: Chl a and excitation pressure over PSII were controlled by photon flux and inversely correlated with each other. Protein and glucose also correlated with each other and were controlled by host factors although HT and FAA had an antagonistic effect of stimulation and inhibition of these parameters respectively. The principal component analysis (PCA) evidenced the existence of a general mechanism of glucose release which correlated with protein expression. The HRFs control over the proteome of Symbiodinium explored by SDS-PAGE analysis displayed different bands with differential expression among types and treatments. Some of these proteins may be related with the stimulation and inhibition of the mechanism of translocation of glucose that were found. Identification of these proteins would probably clarify the physiology behind the translocation of glucose from the Symbiodinium cell to its coral host. The proteome response and physiology of Symbiodinium was assessed by the interaction of different light environments with different temperatures. Growth patterns and photochemical measurements confirmed unique acclimation processes to light and temperature conditions across the three Symbiodinium types. These acclimation strategies appeared regulated by the differential expression of proteins involved in photosynthesis, protein modification, energy metabolism and cell maintenance. This differential expression of the proteome related to these processes seemed associated with the activation of alternative electron transport pathways to balance ATP production, regulate energy metabolism and fuel the cell at the different experimental light and temperature conditions. The results obtained provide a broader view on how the differential regulation of the proteome mediates the physiological plasticity across types of Symbiodinium to photoacclimate to different light enviroments, to acclimate to high temperature and to respond to stressful conditions determining the functional diversity existing in this genus of coral symbionts.

Abstract:

The impulse to beautifying clothing through acts of adornments or embellishments is an innate characteristic of humans. The added decorative details are used for identification and visual communication by the wearer and comprehension and visual appreciation by the viewer. This thesis investigates the recent attention to female modesty, labeled as the Modesty Movement--the community that has developed around the apparel segment of the Movement and the framework of the behavior encompassing the participants within Movement. Additionally, the thesis focuses on adornment through the lens of textile/surface design (embellishment) specific to the Greater Middle East and the northern provinces of India and its application to modest apparel. Surface design is defined as manipulation of a textile beyond the woven construction, in this context it is applied to women’s apparel that covers the head and chest. Through a series of experiments using light, sound and motion the thesis examines how the use of of adornment simultaneously conveys identity and conceals the wearer.

Full text

Abstract:

This thesis proposes that conscious and increased co-operation and coordination of the relationship between investment tribunals and domestic courts can greatly improve the efficacy of the international investment arbitration system, and further the rule of law. The extent of the power both forums wield, the level of influence both systems have on each other and the critical roles both systems play in the resolution of investment disputes warrant a systematic approach to cooperation and coordination. This study finds justification for this proposition by analyzing the policy implications of investment arbitration outcomes. It goes on to explore the relationship between domestic courts and investment tribunals by examining the roles they play and the areas of jurisdictional friction between the two systems. The core issues addressed include the jurisdiction and competence of international investment tribunals and domestic courts in the resolution of investment disputes; the support roles of domestic courts; anti-suit/anti-arbitration injunctions; pre-conditions to arbitration; the effects and implications of the review of investment tribunals’ decisions by domestic courts, and the review of the lawfulness of the conduct of domestic judicial systems by investment arbitration tribunals. In addressing these issues, the work examines the extent to which domestic courts and international arbitration tribunals should accord deference to each other with respect to their involvement in the resolution of investment disputes. Based on the analysis of the areas of intersection between the domestic and international investment dispute settlement systems, instances of ‘positive interactions’ are highlighted and encouraged. The study also proposes ways in which further cooperation and coordination can take place. In making these proposals, and acknowledging the differences that exist, this thesis considers the collaboration between other international adjudicatory bodies and domestic courts so as to distill lessons for the international investment arbitration system.

Abstract:

A major initiative in the U.S. healthcare care industry is to establish a nationwide health information network securing the sharing of information between all involved U.S. healthcare stakeholders. However, implementing an interoperability solution is a massive, complex, and enduring effort with significant challenges such as inconsistent technology and data standards, as well as complex privacy and security issues. The purpose of this qualitative, case study is to examine the impacts of interoperability initiatives involving the U.S. government and to provide an understanding of the information governance and security risk as standards that are vendor-neutral and trustworthy. This qualitative case study was conducted using federal participants who are health information management (HIM) and health information technology (HIT) professionals working in the Washington DC metropolitan area. The participants' interview data revealed nine major themes; patient identification matching, payment claims and auditing, information sharing, data stewardship, regulatory compliance, technology enhancements, training and certification, standards optimization, and value-based care. The implication of the study's themes showed interoperability is beneficial to the healthcare industry, but there is a greater need for technology and data standardization, information governance, data stewardship, and a greater understanding of federal and state data privacy and security laws. Future recommendation for practices discussed; policy and regulatory adjustments to enhance auditing and compliance, establish a healthcare data ecosystem to improve data and information governance, and technology alternatives such as master data management and white space data. Recommendation for further research included expanding the sample population to compare other federal organizations or the United Kingdom's HIT interoperability project initiative.

Full text

Abstract:

The mediterranean ecosystems of the south-western Cape, South Africa occur mainly on nutrient-poor acid sands and less often on limestone and mixed limestone soil types which support a high species diversity of Fabaceae. This species richness and diversity is suggested to be a result of a high incidence of microsymbiont/host specificity among the fynbos Fabaceae (Cowling et al. 1990). This hypothesis by Cowling et al. (1990) has ignored other factors which may possibly play a major role in microsymbiont/host relationships in the Cape Floristic Region, such as soil conditions, and bacterial strain competition which may also influence patterns of nodulation in the region. Cowling et al.'s (1990) hypothesis was speculative and was without any experimental basis. In this thesis investigations were carried out to assess the applicability of this hypothesis to fynbos, while at the same time other factors that could affect the microsymbiont/host relationship in fynbos were investigated. In order to test Cowling et al.'s (1990) hypothesis, various complementary methods were used to assess the nodulation patterns of several indigenous fynbos species. Extracts from a range of soils differing in chemical and physical properties were used to inoculate test species, and their nodulation parameters observed. However, a second more specific approach was used to confirm the results of the previous study. This method involved cross-inoculation of indigenous test species used in the previous study with nodule homogenates prepared from other fynbos species originating from various sites within the Cape Floristic Region.

Abstract:

The relationship between plants and rhizosphere bacteria collected from a 45 year old permanent pasture was investigated. Several methods of strain identification within Rhizobium trifolii were evaluated. Separation of bacterial isolates based on differences in intrinsic antibiotic resistance was not appropriate because strains developed hybrid resistance patterns when grown in a common broth. Serological analyses of bacterial antigens using polyclonal antiserum yielded two reliable methods for identifying R. trifolii isolates. Agglutination and immunofluorescence procedures were not useful in distinguishing these strains but immunodiffusion and the enzyme-linked immunosorbent assay (ELISA) were highly suitable. Adaptation of the ELISA allowed isolates to be identified directly from individual root nodules without first subculturing the bacteria. A strain of Bacillus polymyxa isolated from the same pasture was shown to stimulate growth of crested wheatgrass (Agropyron cristatum L.) and white clover (Trifolium repens L.). The primary manifestation of the effect was increased root weight (P < 0.05), but shoot responses were also observed. Perennial ryegrass (Lolium perenne L.) generally reacted negatively to inoculation with this bacterium. Further stimulation of growth was noted when ramets of the white clover genotype homologous to (sharing a common origin) B. polymyxa were inoculated in pure stands (P < 0.05). Clones of the homologous perennial ryegrass genotype also showed a yield increase from slightly below control levels to slightly above them when tested in a similar manner. Detailed analysis of the crested wheatgrass response to inoculation revealed that bacterial production of indole acetic acid was the most likely cause of the growth stimulation. Other bacterial characteristics such as the ability to fix atmospheric nitrogen or to solubilize organic phosphorus were concluded to be unrelated to the growth response. Co-adaptive compatibility between genotypes of L. perenne and T. repens was not apparent when the effect of R. trifolii was ignored. However, when clones of pasture plants that had been neighbours in the field were inoculated with R. trifolii isolated from root nodules of the "parental" clover genotype, biotic specialization between the pasture plants became evident. The magnitude of the effect, which was characterized by superior white clover yields (P < 0.05), could be largely accounted for by the presence of the adapted L. perenne/R. trifolii combinations, regardless of the white clover genotype. Since T. repens was the dominant component in the species mixture, these trends were also apparent when total forage biomass was analyzed (P < 0.05). However, ecological combining ability was found to be lowest in these associations (P < 0.05). Similar experimentation with isolates of B. polymyxa (or B. polymyxa-like organisms) was performed. Again the grass/bacteria combination was shown to be influential in the growth response as the presence of homologous L. perenne/B. polymyxa combinations resulted in superior white clover and perennial ryegrass performance (P < 0.05). When T. repens was inoculated with a mixture of R. trifolii strains, unrelated isolates formed more root nodules than did homologous ones (P < 0.05). The presence of perennial ryegrass did not mitigate this effect. However, when homologous R. trifolii was administered as a single strain inoculum, yield advantages in white clover were observed (P < 0.05). If B. pol ymyxa was present, homologous strains of R. trifolii tended to form most of the root nodules regardless of the T. repens or L. perenne genotypes. The significance of the yield advantages observed in various two and three-way plant/microbe genotype combinations is discussed with respect to above ground plant performance.

Abstract:

This thesis analyses the interaction between missionary medicine and Ndyuka medicine from the perspective of a Baptist missionary nurse operating a clinic in the village of Lantiwei in Suriname. Based on two months of anthropological fieldwork conducted in the summer of 2014, this thesis argues that in her everyday practice of medicine, the Baptist nurse is dependent on the cooperation of a local Ndyuka healer and his family to such an extent that their working together can be regarded as a social form of symbiosis. This thesis furthermore demonstrates that the Baptist nurse has incorporated Ndyuka ideas to her understanding of illness and death, and that even though she continues to abhor and reject the practice of Ndyuka medicine as a form of devil worship, she recognizes its spiritual powers. Taken together, these findings show that an opposition between missionary medicine as a—perhaps unwitting—agent of modernity and local Ndyuka medicine as a ‘traditional’ form of medicine increasingly superseded by ‘modern’ medicine, is fictitious, and that the lack of scholarly attention to the interaction of missionary medicine with local practices of medicine demontrates anthropology’s obsession with the ‘traditional’ ‘Other’.

Full text

Abstract:

The cyanobacteria are a unique and important phylum of bacteria. They are photosynthetic, thought to be responsible for up to half of all atmospheric carbon dioxide fixation, and are capable of fixation of atmospheric nitrogen, thus contributing to the nitrogen cycle. Many species readily form symbiotic relationships with a variety of other organisms, from marine animals, through mosses and lichens, to large land plants. The precursor to the modern chloroplast is thought to have been a cyanobacterium. They have played, and continue to play, a huge part in the formation of the environment of the Earth. Using a wide array of monoclonal antibodies to a variety of plant cell wall components, along with a specific reagent (~-glucosyl Yariv reagent), this study has shown that free- living cyanobacteria have components expressed on the outer surfaces of cells with characteristics very much like those of arabinogalactan-proteins (AGPs). AGPs are a class of plant cell wall glycoproteins with a large number of proposed actions in plant growth, development and signalling (including symbiotic signalling). Bioinformatic analysis of the model symbiotic cyanobacterial proteome of Nostoc punctiforme 29133 has suggested that it contains several proteins which share critical characteristics with known plant AGPs. Wider bioinformatic analysis hints at the presence of AGP-like proteins in a wide variety of ; other cyanobacterial species. The study concludes that free-living cyanobacteria produce AGPs and proposes a role for these in extracellular signalling. The study also uses an array of plant cell wall-specific monoclonal antibodies to investigate the potential interactions between Nostoc, a symbiotic cyanobacterial genus, and two of their symbionts, the angiosperm Gunnera and the liverwort B/asia. The presence of AGP- specific epitopes, along with pectins and hemicelluloses at the symbiotic surface is demonstrated. Other than AGPs, analysis suggests that symbiotic cyanobacteria lack the genetic capability to produce these components, and hence it is hvpotheslsed that the plant produces these at the symbiotic surface. Potential roles for these are discussed, including roles in symbiotic signalling and helping the cyanobiont evade plant immune responses.

La teoria de la gestió dels estats d’ànim estipula que les persones intenten readaptar el seu entorn d’estímuls per incrementar la durada i la intensitat dels bons moments i reduir la intensitat i la durada dels mals moments. En conseqüència, aquesta recerca té una triple finalitat: 1) explicar amb detall el procés de gestió de l’estat d’ànim col•lectiu en els llocs personals de les xarxes socials, incloent-hi la creació selectiva i el consum selectiu de continguts; 2) il•lustrar sobre les conseqüències d’una cultura de gestió de l’estat d’ànim col•lectiu en les xarxes socials, i 3) identificar formes en què les marques es poden afermar en una cultura de gestió dels estats d’ànim a les xarxes socials i a través d’elles. A partir de 15 llargues entrevistes de més de dues hores de durada cadascuna i de les dades recollides durant vuit mesos d’informació online dels perfils de Facebook dels enquestats, trobem que les persones creen col•lectivament uns continguts en els seus llocs personals de les xarxes socials que són bàsicament positius i divertits, que fan que els continguts visibles a les xarxes socials siguin predominantment positius i divertits. Aquest fenomen s’explica estudiant detingudament els tipus de continguts que creen les persones, els tipus de continguts que no creen, els tipus de continguts que consumeixen online i els que no consumeixen. Les nostres conclusions demostren que l’ús de les xarxes socials implica una combinació de comportaments contraris i contradictoris.

Research on the consumption of personal social media sites, such as Facebook, YouTube and Instagram, has been dominated by identity-based projects in which individuals use the online space to create and project their desired identities through the process of image-management. In this research, an alternative conceptualization of social media usage, comprising content creation and consumption, is presented using mood management and selective exposure theory derived from media psychology. Mood management theory stipulates that individuals attempt to rearrange their stimulus environment so as to increase the duration and intensity of good moods and reduce the intensity and duration of bad ones. Subsequently, the aims of this research are threefold: (1) to elaborate on the process of collective mood management on personal social media sites, including selective content creation and selective content consumption; (2) to shed light on the consequences of a culture of collective mood management on social media networks; and (3) to identify ways in which brands can leverage themselves in a culture of mood management on and through social media. Using 15 long interviews spanning two hours each and data collected from eight months of online observation of the respondents’ Facebook profiles, I find that individuals collectively create content on their personal social media sites that is primarily positive and entertaining, leading to predominantly positive and entertaining content visible on social media networks. This phenomenon is explained by elaborating on the types of content that individuals create, the types of content they do not create, the types of content that persons consume online and those which they do not consume. The findings demonstrate that social media usage involves a combination of contrary and contradictory behaviours. Understanding the culture created by consumers of social media is not only necessary for brands to determine how to penetrate and engage in such a culture, but is also relevant for brands to find avenues for growth beyond two-way communication and relationship building, in which experiences are also delivered through social media networks.

Full text

Abstract:

The Nanoarchaeota are an enigmatic lineage of Archaea found in deep-sea hydrothermal vents and geothermal springs across the globe. These small (~100-400 nm) hyperthermophiles live ectosymbiotically with diverse hosts from the Crenarchaeota. Despite their broad distribution in high-temperature environments, very few Nanoarchaeota have been successfully isolated in co-culture with their hosts and nanoarchaeote genomes are poorly represented in public databases. However, the Nanoarchaeota provide unique insights into the structure and function of symbiosis in the archaeal domain. This study describes novel nanoarchaeotes from multiple geothermal habitats, using a combination of direct cultivation techniques and genomic analysis. A new nanoarchaeote from a New Zealand hot spring, Candidatus Nanoclepta minutus, was isolated in co-culture with its host. Like other terrestrial Nanoarchaeota, Cand. Ncl. minutus harbors genes for gluconeogenesis and archaeal flagella. Zestosphaera tikiterensis, the New Zealand host, was also isolated in pure culture and characterized. Phylogenetic analysis showed that both Cand. Ncl. minutus and Z. tikiterensis are new genera in the Nanoarchaeota and Crenarchaeota, respectively. Metagenome-assembled genomes (MAGs) from the Nanoarchaeota were also recovered from deep-sea hydrothermal vent sites. These MAGs capture a wide range of diversity in the Nanoarchaeota, representing three new species and two novel genera. Key nanoarchaeotal features were identified in the MAGs, including marker genes for archaeal flagella, gluconeogenesis and CRISPR-Cas regions. These studies greatly contribute to our understanding of nanoarchaeotal ecophysiology and provide key insights into the coding potential and diversity of Nanoarchaeota and their hosts.

Full text

Abstract:

As sessile organisms, plants evolved a plethora of defenses against their attackers. Given the role of plants as a primary food source for many organisms, plant defense has important implications for community ecology. Surprisingly, despite the potential to alter entire food webs and communities, the factors determining plant investment in defense are not well-understood, and are even less understood considering the numerous symbiotic interactions in the same plant. Legume-rhizobia symbioses engineer ecosystems by fixing nitrogen from the atmosphere in trade for plant photosynthates, yet connecting symbiotic resource exchange to food web interactions has yet to be established. Here I test how rhizobia influence plant defense and tritrophic interactions in lima bean (Fabaceae - Phaseolus lunatus L.): a model plant in chemical ecology research characterized by a broad range of different defenses. Examining suites of traits among lima bean genotypes, highly cyanogenic cultivars and wild type plants (high cyanotypes) produce more hook-shaped trichomes, as a putative combined approach of chemical and mechanical defenses, forming defense syndromes to protect against multiple feeding guilds (Chapter 2). Testing costs that may have contributed to forming tradeoffs among strategies, high cyanotypes show reduced fitness under plant-plant competition relative to low cyanotypes, but when challenged with herbivory, high cyanotypes fitness reductions are no longer evident (Chapter 3). Young leaves, not reproductive organs, are the most cyanogenic lima bean organ, and removal quantitatively decreases fitness, supporting assumptions that the most valuable tissues will be most highly defended (Chapter 4). Testing the degree to which nitrogen-fixing rhizobia contribute to cyanogenesis, high cyanotypes form more nodules than low cyanotypes. Quantitative relationships between nodule number and plant traits highlight the role symbiotic investment plays a role in plant defense and nutritive phenotype, while simultaneously, genotypically-determined levels of defense shape plant investment in symbiosis (Chapter 5). Interestingly, traits that trade off by cyanotype (i.e. high cyanogenesis but low indirect defense) reflect the patterns in plants with nitrogen-fixing rhizobia. Rhizobia-inoculated lima beans show reduced indirect defenses, recruiting fewer parasitoid wasps (Chapter 6) and predatory ants (Chapter 7). Examining plant-ant attraction in greater detail, ants prefer headspace regions above EFN droplets, corresponding with species-specific differences in suites of volatiles, indicating EFN, like floral nectar, can be scented to manipulate insect behavior (Chapter 8). Overall, understanding when investing in traits to recruit predators is more effective than investing in defensive chemistry, and how particular ecological contexts, such as symbioses can influence the outcome of defense allocation strategies remains a fascinating area of research. Determining the mechanisms underlying why rhizobia and other belowground microbial symbionts influence their host plants' above ground interactions, whether plants traits affected by symbiotic microbes are simply a function of the costs and benefits from resource exchange, or whether symbionts can influence the success of primarily direct versus indirectly defended plants is an important question for understanding complex trophic systems and connecting to agricultural implications for more effective biological pest control.

Abstract:

A growing understanding of complex biotic interactions clarified the importance of symbioses with respect to the ecology and evolution of life. In particular, knowledge of symbioses between eukaryotes and microorganisms such as bacteria and fungi has revolutionized the fields of medicine and agriculture, and made clear the roles of microbes in fostering human and environmental sustainability. For example, diverse fungi associate with the seeds of plants following dispersal. These fungi can influence seed survival and germination in a host-specific and spatially explicit manner, thus influencing plant community dynamics in agricultural and natural systems. In species-rich tropical forests, seed-fungus interactions are emerging as one of the most important aspects of plant demography and community ecology. However, even closely related fungi can have opposing effects on seeds of particular plants, such that mechanisms influencing host-specific effects require further attention. Such mechanisms can include genomic traits of fungi and hosts, and the environmental context of interactions. However, studies have shown that many fungi also harbor endosymbionts than can influence their functional traits. In particular, fungi often harbor endohyphal bacteria that influence fungal phenotypes. This suggested the potential for similar, co-occurring microbes to influence the ecology of seed-associated fungi. Here, I explore the diversity, evolutionary relationships, and influence on fungal phenotypes of endohyphal bacteria inhabiting seed- and leaf-associated fungi with a focus that begins in tropical forest ecology and expands to include gene expression in an emerging model system from the temperate zone. To determine the occurrence, abundance, taxonomic diversity, and phylogenetic diversity of endohyphal bacteria among tropical seed-associated fungi, my coauthors and I used PCR and fluorescence microscopy to screen members of two common orders of seed-associated fungi, comparing their communities to those in closely related foliar endophytic fungi. We revealed a high frequency and diversity of endohyphal bacteria among both groups of fungi. We then used phylogenetic and community ecological analyses to show a lack of congruence between phylogenies of bacteria and fungi. Although seed-associated and foliar endophytic fungi share evolutionary histories, they harbor distinct endohyphal bacterial communities. To explore the influence of endohyphal bacteria on fungal phenotypes important for interactions with seeds, my coauthors and I examined a single fungus-bacterium pair consisting of a member of a well-known group of pathogenic fungi found to harbor an endohyphal bacterium closely related to those with known chitinolytic activity. We created fungal clones that were free of endohyphal bacteria, and carried out a phenotypic microarray assay comparing use of 95 unique carbon sources by cured and uncured clones. Across the majority of substrates, the fungal clones harboring endohyphal bacteria grew more rapidly and to a greater extent than the cured clones. Thus the endohyphal bacterium was associated with broader substrate use and more effective use of a variety of substrates relevant to plant biology, including seed germination. To assess the influence of endohyphal bacteria with respect to the outcomes of seed-fungus interactions, my coauthors and I examined six fungus-bacterium pairs and their interactions with the seeds of five tropical pioneer tree species. We showed that although endohyphal bacteria have little impact on colonization of seeds by fungi, they significantly altered the survival and germination of infected seeds. In most cases, endohyphal bacteria reduced the negative impacts of fungi on seeds: strains harboring them responded more similarly to uninoculated controls, whereas strains cured of them exhibited significantly reduced survival and germination. Seeds infected by fungi of the same genotype that differ with respect to the identity of their endohyphal bacteria exhibited differences, but so did seeds infected by strains of those isolates not harboring bacteria, suggesting that factors in addition to the presence of endohyphal bacteria can drive variation in the outcomes of seed-fungus interactions. Together these analyses suggest intricate interactions between fungi and bacteria that result in context-dependent outcomes. This turned our focus to gene expression as a means to understand mechanisms of interactions between endohyphal bacteria and their fungal hosts. Last, my coauthors and I describe methods we developed to co-culture fungi and their endohyphal bacteria for downstream analysis of differences in gene expression among a fungus-bacterium pair and axenic cultures of each symbiont. We focused on an emerging model system: a foliar endophytic strain of Pestalotiopsis aff. neglecta (Ascomycota) known to harbor an endohyphal bacterium in the genus Luteibacter (Xanthomonadaceae). The focal bacterium is in part reliant on its host fungus for acquisition of certain sulfur-containing compounds such as sulfate. We showed that inoculating a low-methionine growth medium with bacteria recovered in exponential phase from a high-methionine medium supports growth suitable for comparing axenic growth with that in co-culture with its host fungus. Although bacterial cell density in co-cultures was significantly greater than that in axenic cultures, the opposite was true for the host fungus. We expect results from transcriptomics analyses to reflect partial reliance on– and antagonism of Pestalotiopsis by Luteibacter, and here present the first pipeline of methods for examining gene expression for a facultatively symbiotic endohyphal bacterium and its host, a member of the most species-rich and economically important fungal phylum.

Abstract:

Different challenges arising from increasingly uncertain and unpredictable environmental and economicconditions have been shifting the focus of public governance and socio-economic development. Morerecently, empirical studies have demonstrated a transitional epoch in which humanity is currently in: TheAnthropocene, as well as its harmful effects that degrade the biosphere, and thus our economic, political,social well-being. The casual dynamics of climate change and its impacts on life-supporting ecosystemshas increasingly been recognized by a resilient approach which incorporates adaptive processes andschemes, allowing public governance to embrace the changes rather than control uncertainty. Thisresearch introduces the interwoven concepts of adaptive capacity, adaptive governance, and resiliencewithin a social and environmental framework. It provides a review of how these concepts support aparadigm shift to mitigating current and future challenges—understood through a multidisciplinaryapproach, and how scholars have sought to develop a blueprint to improve the need to foster and mobilizeadaptive capacity within the governance of the commons. In Sweden, key governmental and businessleaders have shown the ability to foster environmental governance that is capable of developing analternative form of planning, implementing, and managing public policy. Moreover, Sweden’s concertedmultilevel governance and public policy efforts have promoted an all-encompassing generational, mainlythrough: coordinated environmental policies and private, public, and civil society partnerships. Theseinitiatives have led to innovative technologies and projects (e.g. urban vertical farming technology) as wellas cross collaboration and integration of companies and industries in order to achieve economic, social,and environmentally symbiosis.

Abstract:

The specific instances of R.H.W. Shepherd and H.I.E. Dhlomo are used in this thesis to investigate some of the many factors that influence the formation of a colonial literature, such as politics, social structures and personal ideals. By isolating the Lovedale Mission Press ~s a "contact zone" - a·place where the cultures of the colonizer and the colonized come into direct contact with each other - it is possible to trace how the interaction between these cultures shaped the writing of a particular African writer, H.I.E. Dhlomo. This is done through an analysis of historical factors that shaped the policy of the Lovedale Mission Press in the twentieth century: the development of liberalism in South Africa, the·role of the missionary in African education, the function ofa liberal magazine such as The South African Outlook and the appointment of an ambitious missionary, R.I.W. Shepherd, to the position of Director of Publications. This necessarily included a study of Shepherd's vision of African literature. On the other hand, this study takes cognisance of the factors that shaped Herbert Dhlomo's vision of literature: the development of African nationalism, the entrenchment of segregation as a politial doctrine, and most importantly, his struggle to have his creative writing published by the Lovedale Press. It is shown how Shepherd's vision of what African literature should entail contrasted with Dhlomo's, and how, as a result, Dhlomo deliberately structured his critical writing as a response to Shepherd's Eurocentric approach to African literature.

Abstract:

Plant growth-promoting bacteria (PGPB) have been studied in many agriculturally interesting plants, but never in pitcher plants. Sarracenia oreophila (the green pitcher plant) is an endangered species in Georgia, Alabama, and North Carolina (Rice 2010). With the help of Dr. Jim Spain's lab, a previous student in Dr. Gerald Pullman's lab discovered evidence that nitrogen-fixing bacteria (Burkholderia spp.) live within these pitcher plants. This study aims to determine whether these nitrogen-fixing bacteria confer a benefit to their host plants by providing fixed nitrogen. To do this, pitcher plants were inoculated with the Burkholderia and grown on a control medium, a medium without sugar (as the sugar causes the bacteria to grow until they hinder the plants), various media that are missing nitrogen-containing compounds usually provided in growth media, and a medium completely lacking nitrogen. These plants were compared to control plants on the same media that had not been inoculated with Burkholderia. The plants' biomass and root growth were measured. The data suggest that Burkholderia may stimulate plant biomass growth when sufficient nitrogen is present and there may be a nitrogen-threshold that needs to be met in order to sustain the Burkholderia-Sarracenia symbiosis. Also, the Burkholderia has a negative effect on roots grown in high-nitrogen media, possibly due to competition for nutrients.

Abstract:

La compréhension des interactions qui associent les plantes et les microorganismes du sol est une étape incontournable pour une gestion durable de nos écosystèmes notamment en agriculture. Parmi les services écosystémiques résultant de leurs interactions, on peut citer la productivité végétale répondant, en partie, aux besoins alimentaires de la population mondiale et la régulation des cycles biogéochimiques. Les services écosystémiques, qui émergent de telles interactions, reposent sur des liens trophiques pouvant être représentés par un compromis entre coûts et bénéfices pour les différents partenaires de l’interaction. Les plantes, organismes autotrophes ou producteurs primaires, sont des organismes clefs qui font entrer le carbone dans l’écosystème, via la photosynthèse. Une partie de ce carbone est libérée sous forme de molécules plus ou moins complexes, au niveau de leurs racines, par le processus de rhizodéposition. Ces composés servent de molécules signal et de nutriments pour les microorganismes du sol, essentiellement hétérotrophes, c’est l’effet rhizosphère. Ce processus est donc coûteux pour la plante mais bénéfique aux microorganismes. Les microorganismes contribuent, en retour, à la nutrition et la santé des plantes ce qui est coûteux mais leur assure une source bénéfique de nutriments. Ces échanges trophiques reposent néanmoins sur un équilibre dépendant des conditions biotiques et abiotiques qui affectent chaque partenaire. La biodiversité microbienne, de par la multitude d’interactions au sein des communautés microbiennes, est un facteur biotique important. Parmi les facteurs abiotiques, le contexte environnemental actuel, soumis aux changements globaux, est propice à une déstabilisation de ces interactions. L’objectif de ce travail est donc de comprendre comment vont varier les coûts et bénéfices, pour chaque partenaire, suite à des modifications de l’environnement affectant l’un ou l’autre. L’intérêt étant de savoir si les bénéfices pour les plantes et les microorganismes, qui permettent les services écosystémiques, seront affectés. Pour répondre à cet objectif, un cadre d’interaction plantes-microbes simplifié a été choisi et une déstabilisation, au niveau de la plante, a été effectuée au moyen d’une augmentation en CO2 atmosphérique. L’interaction entre Medicago truncatula et Pseudomonas fluorescens a ainsi été étudiée. Les interactions ont ensuite été complexifiées en utilisant une communauté microbienne dans son ensemble et, cette fois, la modification a été appliquée au compartiment microbien soumis à une dilution de sa diversité. L’effet du gradient de diversité microbienne obtenu a été mesuré sur la croissance et la reproduction de trois espèces végétales modèles (Medicago truncatula, Brachypodium distachyon et Arabidopsis thaliana). Enfin, l’analyse s’est focalisée sur la communauté microbienne en identifiant la part active, c'est-à-dire les microorganismes qui utilisent les composés libérés par la plante. Ces microorganismes, qui interagissent réellement avec la plante, ont été détectés grâce à une analyse ADN SIP utilisant l’isotope 13C. Les principaux résultats observés, que la modification affecte l’un ou l’autre des partenaires, sont une déstabilisation des coûts et bénéfices. La première étude montre une variation temporaire des interactions en faveur de la plante en condition de CO2 augmenté. Dans le cas d’une dilution de la diversité microbienne, les coûts pour la plante sont conditionnés par la dépendance naturelle des plantes vis-à-vis des microorganismes symbiotiques qui interagissent avec le reste de la communauté. Cela est confirmé par la dernière expérimentation qui met en évidence les interactions microbes-microbes qui conditionnent la structure de la communauté microbienne interagissant avec la plante.

Understanding the interactions that bind plants and soil microorganisms is an essential step for the sustainable management of ecosystems, especially in agriculture. The ecosystem services resulting from such interactions include plant productivity which responds, in part, to the food requirements of the world's population and the regulation of biogeochemical cycles. These ecosystem services depend on trophic links between the two partners in the interaction and can be represented by a tradeoff between the costs and benefits for each partner. Plants, being autotrophic organisms or primary producers, are key organisms which introduce carbon into the ecosystem, through photosynthesis. Part of this carbon is released as more or less complex molecules at the roots level, thanks to the rhizodeposition process. These compounds act as signal molecules and nutrients for soil microorganisms, which are mainly heterotrophic, in the so-called rhizosphere effect. This process is costly for the plant but beneficial to the microorganisms. In return, microorganisms contribute to plant nutrition and health, which is costly but provides them with a beneficial source of nutrients. These trophic exchanges, however, are based on a balance which depends on the biotic and abiotic conditions that affect each partner. Microbial biodiversity, through the multitude of interactions occurring within microbial communities, is a significant biotic factor. Among the abiotic factors, the current environmental context, subject to global change, is tending to destabilize these interactions. The objective of this work was to understand how environmental changes affect the costs and benefits for each partner by applying changes to one or the other, the aim being to determine whether these changes would affect the benefits for plants and microorganisms that provide ecosystem services. To achieve this objective, a simplified framework for plants-microbes interaction was first chosen. Destabilization at the plant level was carried out by increasing the atmospheric CO2 and studying the interaction between Medicago truncatula and Pseudomonas fluorescens. The interactions were then made more complex by using a whole microbial community but this time the change was applied to the microbial compartment by subjecting it to diversity dilution. The effect of the resulting microbial diversity gradient was measured on the growth and reproduction of three model plant species (Medicago truncatula, Brachypodium distachyon and Arabidopsis thaliana). Finally, the microbial community was subjected to a DNA SIP analysis, with the isotope 13C, to identify the active portion, i.e., those microorganisms which really interacted with the plant and used compounds released by it. The main result, when the change affected one or other partner, was a destabilization of the costs and benefits. The first study showed a transient variation in the interactions in favour of the plant under increased CO2 conditions. In the case of a dilution of microbial diversity, the costs for the plant are conditioned by the natural dependency of plants on symbiotic microorganisms that interact with the rest of the community. This was confirmed by the last experiment that highlighted the between-microbes interactions which determined the composition of the microbial community that interacted with the plant. This work has helped to clarify the functioning of relationships between plants and soil microbes and the factors that contribute to their maintenance which is essential to the functioning of ecosystems. These studies also provide ways for predicting the impacts of global change on ecosystems. The conservation or restoration of ecosystem services is essential for human well-being

O gerenciamento dos resíduos industriais tornou-se um tema estratégico nas empresas. O aumento da consciência ambiental por parte dos consumidores e das exigências legais tem levado as empresas a rever sua postura no que tange ao descarte dos seus resíduos industriais. A análise da competitividade das cadeias de suprimentos não pode se restringir apenas ao tradicional fluxo unidirecional de produtos. O canal reverso de resíduos também deve ser avaliado, visando fechar ciclos de reutilização de materiais ou destinar resíduos do processo produtivo para outras aplicações. Neste contexto, a indústria siderúrgica destaca-se pela sua capacidade de utilizar sucatas metálicas como matéria-prima e de gerar resíduos capazes de serem utilizados como matéria-prima em outros ramos industriais. O objetivo deste estudo é analisar o potencial de formação de cadeias ambientalmente sustentáveis por meio do reaproveitamento de resíduos industriais advindos da cadeia siderúrgica. Para tanto foram realizados dois estudos de caso. No primeiro foi avaliado como as relações entre sete empresas pertencentes a uma mesma cadeia de suprimentos podem contribuir para romper barreiras ou estimular o reuso de resíduos. No segundo estudo de caso foram avaliados quatro principais resíduos gerados por uma usina siderúrgica e as possibilidades e limitantes para sua utilização como matéria-prima em outras atividades econômicas. Os resultados demonstraram que a maioria dos relacionamentos visando a reutilização de resíduos tem natureza estritamente comercial, sendo o reuso acentuado quando o nível de dependência das empresas com relação ao resíduo é maior. Mesmo havendo um elevado grau de dependência, fatores externos podem inviabilizar a utilização de resíduos. O custo inviabiliza a instalação de novas operações industriais visando apenas a utilização de resíduos industriais como matéria-prima. Extrapolar a relação comercial das empresas para um caráter colaborativo pode auxiliar a atenuar estes fatores externos, quebrar barreiras e estimular o aumento na reutilização dos resíduos. Salienta-se, porém, a existência de oportunidades para a instalação de empresas ou cooperativas capazes de retrabalhar o resíduo siderúrgico visando sua utilização em outras aplicações.
The industrial waste management becomes a strategic issue in business. The increase of environmental awareness by consumers and the legal requirements has led companies to review their position regarding face the disposal of their industrial waste. A competitive analysis of supply chains can not be restricted to the traditional one-way flow of products. The reverse channel of wastes should also be evaluated, aiming to close the cycle for the reuse of materials or the use of industrial waste in other applications. In this context, the steel industry distinguished by its ability to use scrap metal as raw materials and generate industrial wastes capable of being used as raw material in other industrial sector. The objective of this study is to analyze the potential to establish an environmentally sustainable supply-chain through the reuse of industrial waste arising in the steel industry. To accomplish this, two case studies were conducted. In the first study was reported the relations between seven companies belonging to the same supply chain and discussed how these relations can help to break down barriers and encourage the reuse of waste. In the second case study were assessed four main waste generated by a steel mill, evaluating the possibilities and limits for the reuse of the waste as raw material in other economic activities. The results showed that most relationships order to reuse the waste is strictly commercial. The reuse increases when the companies levels’ of dependency for the waste is higher. Even with a high degree of dependence, external factors may prevent the use of waste. Extrapolate the business relation of the companies for a collaborative relationship can help to mitigate these external factors, break down the barriers and increase the reuse of waste. Cost prevents the installation of new industrial operations to only the use of industrial waste as raw material. However there are opportunities for the installation of companies or cooperatives able to rework the steel waste for use in other applications.

Abstract:

Les microorganismes agissent comme un puits et une source de N et Pdisponibles car ils sont responsables des cycles biogéochimiques de N et P. La bouclemicrobienne, basée sur la prédation des bactéries par les microprédateurs tels que lesnématodes bactérivores, est considérée comme un facteur majeur de la minéralisation de Net de P dans les écosystèmes terrestres. Cependant, peu de données sont disponibles surl'impact de la prédation par les nématodes sur la nutrition minérale des plantes ligneusesectomycorhizées. Différentes expérimentations ont été conduites pour quantifier le rôle dela prédation des bactéries par les nématodes sur l'architecture et la croissance racinaire, lanutrition minérale (N et P) d'une espèce ligneuse, Pinus pinaster, associée ou non avec lebasidiomycète ectomycorhizien Hebeloma cylindrosporum. Les plantes ont été cultivéesdans un système expérimental simplifié et stérile, et inoculées ou non avec Bacillus subtiliset des nématodes bactérivores (de la famille des Rhabditidae ou des Cephalobidae) isolés àpartir d'ectomycorhizes et de sol provenant d'une plantation de Pin maritime. L'effet de laprédation sur la croissance des plantes et le devenir du 15N bactérien vers les partiesaériennes dépend très fortement de la disponibilité en P du milieu. De plus, la prédationdes bactéries est indispensable pour permettre à la plante d'utiliser le P du phytate, unesource de P organique très peu disponible pour la plante mais très facilement utilisable parB. subtilis car cette bactérie est capable de libérer de la phytase dans le milieu. Cesrésultats ouvrent de nouvelles perspectives pour améliorer l'utilisation du phytate pour lanutrition phosphatée des plantes
Soil microorganisms act as a sink and a source of available N and P bymediating key processes in the biogeochemical N and P cycling. The microbial loop, basedupon the grazing of bacteria by predators such as bacterial-feeding nematodes, is thoughtto play a major role in the mineralization of nutrients such as nitrogen (N) and phosphorus(P) in terrestrial ecosystems. However, little is known about the impact of grazing bynematodes on mineral nutrition of ectomycorrhizal woody plants. Different studies wereundertaken to quantify the role of nematode grazing on bacteria on the root growth andarchitecture, mineral nutrition (N and P) of a woody species, Pinus pinaster, whether ornot associated with the ectomycorrhizal basidiomycete Hebeloma cylindrosporum. Plantswere grown in a sterile simplified experimental system, whether inoculated or not withBacillus subtilis and bacterial-feeding nematodes (belonging to Rhabditidae orCephalobidae families) that were isolated from ectomycorrhizae and from soil of a P.pinaster plantation. The effect of nematode grazing on plant growth and the fate ofbacterial 15N towards plant shoots was strongly dependent upon medium P availability. Inaddition, nematode grazing was required to enable the plant to access P from phytate, awell-known poorly available P source to plants but that was used by bacterial populationsof B. subtilis due to its ability to release phytase in the medium. These results open analternative route to increase the use of phytate for plant P nutrition

Abstract:

Arbuscular mycorrhizal (AM) fungi are root and soil inhabiting symbionts with higher plants. The fungi are especially nutrient-function efficient in nutrient deficient soils. There have been innumerable studies of AM fungal facilitation of plant nutrient uptake in controlled environments. Comparatively little similar investigation has been undertaken in natural soils, including investigation of taxon specific nutrient-function efficiency in the phylum. Plant diversity and frequency, soil chemistry statuses, and AM spore diversity and abundance were sampled in an interrupted-belt transect in an aggrading dune sytem on west-coast India, followed by foredunes and transect nutrient amendment experiments in selected plant species. The transect extends 175 m inland from mean high-water mark (MH-WM). Examination showed nutrients were consistently deficient. A plant zonation pattern and increasing frequency over the transect were indicated, as well as decreasing pH and increasing organic matter (OM)-amendment AM species diversity gradients. Plant zonation does not correlate with soil chemistry. There was a distinct soil transition at the 175 m point and evidence of further system partition between foredune and behind-foredune regions. Plant and AM demographies bore no resemblance suggesting neither is driven by the other. Four AM genera were recovered, Acaulospora, Gigaspora and Scutellospora in high abundance, Glomus in comparatively low abundance. The two co-dominant species, A. spinosa and Gi. margarita, displayed divergent strategies in OM amendment. Certain AM taxa may be functionally associated with particular soil nutrients. There was no evidence of taxon-specific nutrient-function efficiency.

Abstract:

This study explored the reading-subjects relationship to reading and texts, and if this relationship, through metaphors, could be compared to that of a parasite or a symbiosis. In other words the question that was asked was; can the reading-subjects relationship to the written text be compared to that of a parasite and it’s host, or is the relationship more similar to that of a symbiosis? The method for the study has been to find and compare different views on reading and text, that has been presented by a series of different theoreticians. The author’s whose work the study is based upon are Anders Johansson and his studies concerning “good” and “evil”, Martin Borgs work on propaganda and Iser Wolfgangs book The implied reader. The analysis is also based of the worldview presented by the characters in Ray Bradbury’s novel Fahrenheit 451. In conclusion, the parasitic and symbiotic metaphor, could be applied and seen in each off the works listed above, it is however not possible to fully say the relationship is closer to one or the other. Each text works in a network of other texts with all different background and intentions. To be able to fully understand the relationship – further studies must be made.

Abstract:

The objective of this study was to examine the role that customer loyalty and employee enthusiasm can play as a strategic objective to increase sales at MB Silicon Systems. In order to address these two factors from a strategic perspective, elements from various concepts have been used to gain a new understanding of customer loyalty, employee enthusiasm and strategy. The final goal of the study was to use the knowledge gained throughout the report to propose a management framework which can be implemented to give MB Silicon Systems a competitive advantage in its competitive industry.The literature review suggested that a strategy of customer loyalty and employee enthusiasm will result in above average financial performance. Customer loyalty and employee enthusiasm cannot be separated from each other and they are linked by leadership, the vision and core values of the organisation. It is not possible to achieve customer loyalty and employee enthusiasm without the proper formulation and execution of a strategy. Such a strategy needs to utilize core management tools like the Balanced Scorecard which will bridge the vision of the organisation with goal setting mechanisms of motivation. The Balanced Scorecard will ensure that strategic objectives of the organisation will be mapped into the Balanced Scorecard while employees will be rewarded according to achieved targets of these objectives.Surveys which were conducted with customers and employees have shown that MB Silicon Systems performs below international standards with respect to customer loyalty and that the organisation is failing with its existing strategy. The surveys have also shown that employees are demotivated. This state of demotivation results in a lack of teamwork and mistrust between employees. The lack of teamwork and mistrust is only the symptoms of organisational problems which need to be resolved by organisational redesign, implementation of management principles and healthy corporate governance. The low base of loyal customers and the demotivated state of employees is resulting in below average financial performance.A management framework was recommended that will transform a strategy of customer loyalty and employee enthusiasm by using proven management tools. Implementation of the framework will ensure a competitive advantage to MB Silicon Systems which will result in above average financial performance.

The purpose of this paper is to discuss what happens during a psychoanalytic experience, when something with a potential for change and growth is generated and what kind of linking favors it. Also, it runs through a fundamental psychic phenomenon of a specific symbiotic quality, capable of a high degree of regenerative and/or constitutive parts of the self. This paper is justified by the fact that more and more the psychoanalytic process has been seen as a result of the pair s interpenetration (transference/ countertransference) and for what is stimulated in the analyst as knowledge about his/her patient psychodynamics. Some clinical hypotheses have been put forward to explain the occurrences of phenomena that are analogous to a kind of immersion in affectionate dimensions of low awareness but necessary to achieve a deep affectionate interaction that would keep symbiotic fusion fantasies. Seven topics are highlighted in order to corroborate to the institution of a link that could support this symbiotic process and the intensity of the emotions present on it: comprehension, love, confidence, loss, truth, companionship and closeness X distance. Results of this research related to clinical aspects are the maternal holding function, as an integrating experience that follows and supports moments of turbulence, a kind of safety net under the trapeze offering security and also the phenomenon of a symbiosis as a fundamental constitutive part of the psychism. This development of the libido previous to the PS ↔ D oscillation could be part of the same dynamics and then, would be turned into a three-part circulation process: symbiotic, disintegrated, integrated
O objetivo do trabalho é discutir o que acontece na experiência do encontro analítico, na qual gera-se algo com potencial de mudança e crescimento e qual o tipo de ligação que o favorece. Discorre, também, sobre um fenômeno psíquico fundamental, de uma qualidade definida, simbiótica, capaz de um alto grau regenerador e/ou constitutivo do self. Justifica-se por ser o processo psicanalítico, cada vez mais, entendido como o produto da interpenetração do par (transferencial/ contratransferencial) e daquilo que é suscitado no analista como forma de conhecimento sobre a dinâmica do analisando. Levantaram-se hipóteses clínicas, sobre a ocorrência de fenômenos análogos a uma espécie de imersão de determinadas dimensões afetivas, pouco conscientes, porém necessárias a uma interação afetiva profunda que guardaria aspectos de fantasias fusionais simbióticas. Destacam-se sete tópicos que corroboram para a instauração de um vínculo que dê sustentação a esse processo e à intensidade das emoções presentes: compreensão, amor, confiança, perda, verdade, companhia e proximidade X distanciamento. Como resultados dessa pesquisa, evidenciou-se no caso clínico a função de holding materno como experiência integradora que acompanha e suporta momentos de turbulência, uma espécie de rede armada sob o trapézio a oferecer segurança e, também, o fenômeno de uma simbiose fundamental a fazer parte da construção do psiquismo. Esse desenvolvimento da libido anterior à oscilação PS ↔ D, poderia, então, fazer parte da mesma dinâmica que se transformaria em uma triangulação: simbiótico, desintegrado, integrado

Since the global atmosphere's composition has drastically changed because of the excess carbon dioxide, it has become clear that “air” is omnipresent and extremely important for our survival. However, the colorless, tasteless, and odorless nature of the air makes it difficult to detect. In addition, human have been living in complex urban environments for a long time. Because of this, most of us are aware of our planet's environmental problems; for example sometimes we cannot even feel that we are breathing. Our “perception ability” to detect air is decreasing. Humans use scientific and technological research and development, to try to reduce the impact of carbon dioxide on the environment, but we all overlook the fact that plants are “carbon recyclers” in the natural carbon cycle, while humans are “carbon producers”; the two are complementary. We should use this fact to explore our fundamental mutual relationship by examining our “air exchange”. This paper is a study of the “air-exchange system”of building. Take high altitude forest like Chilai Mountains as a research and design base, and use double-layer curtain wall structure consists of ETFE membrane and air separation membrane to create space. It uses special environmental space experience to strengthen people’s ability to perceive air, and to investigate the new symbiotic relationship between human and natural environment.
