Its' digital advertisement model has provided crucial economic backbone to support the proliferation of free digital content around the world. However, the industry is now facing significant challenges and controversy around Ad Blocking. The rapidly rising adoption of Ad Blocking is threatening the fundamentals in the digital advertisement model, and could have a profound impact on digital marketing and Internet content consumption. In this thesis, we research online resources to describe the latest technology and business landscape for the digital marketing industry, including the main digital marketing platforms, and system decomposition for its key subsystem Ad Tech industry. We then introduce the Ad Blocking controversy. We use stakeholder value network analysis to analyze how various market responses to Ad Blocking satisfy the system stakeholder values, hoping to shed lights on possible directions for solving the challenge systematically.<br>by Xiaoming Zhang.<br>S.M. in Engineering and Management

Scott, Rebecca. "The Early Middle Palaeolithic of Britain : origins, technology and landscape." Thesis, Durham University, 2006. http://etheses.dur.ac.uk/2896/.
Full textAbstract:
This thesis examines technological behaviour during the early British Middle Palaeolithic (Late OIS 9-7), as reflected by lithic artefacts. The British data-set, whilst containing few high-resolution sites providing information relevant to ethnographic-scale behavioural reconstruction, actually forms a valuable corpus of well-contextualised locales within a tightly constrained chronostratigraphic framework. Lithic artefacts from these sites can be used to address broader questions concerning the emergence and nature of particular "Middle Palaeolithic" behaviours; specifically, the emergence of, and variability within, Levallois technology in Britain, and increasing complexity in the organisation of technology in the landscape. The assemblages analysed in this thesis comprise the nine best-preserved British sites dated to this period, which can be placed within secure chronological, geographical and ecological contexts. Whilst previous surveys have emphasised the typological composition of such assemblages, this thesis considers the specific technological behaviours evident at particular locales, in terms of which stages of lithic reduction are represented, what specific Levallois preparatory and exploitation strategies were applied, and how the choices between such options are explicable. On this basis, it is possible to discuss the development of a technologically complex treatment of particular places in the landscape during the early Middle Palaeolithic, linked to the increased transport and curation of particular Levallois products. Whilst on a European scale, such patterns are seen as typical of the Middle Palaeolithic but are essentially undated; this study shows that such behaviours are apparent from at least OIS 8 onwards in Britain, with concomitant implications for our understanding of developing Middle Palaeolithic behaviours in Europe.

Full textAbstract:
The Central Anatolian Neolithic tell site of Çatalhöyük has been extensively studied as an unusually well preserved example of an early agricultural settlement. Located on a vast clay plain and occupied continuously for almost 1200 years (7100-5950 cal BC), its large size and artistically rich clay-based material culture point to clay being a major contributor to the community’s subsistence and symbolic needs. However, the prevailing interpretation of the clay-rich landscape appears to contradict this view. Thick impermeable clay beds underlying the areas are thought to have impeded the drainage of seasonal floods, periodically isolating the community in extensive wetlands and forcing a reliance on twelve kilometre distant cereal growing. There is an unresolved tension between the material culture and landscape view of what clay truly afforded Çatalhöyük. The aim of this thesis is to establish the full role of clay in Çatalhöyük’s success, and is first tasked with resolving this tension. The approach taken differs from the top-down single group artifact studies and from landscape models that offer a regional explanation but disregard local actualities. Recognising that clay material culture and clay landscape at Çatalhöyük were intimately linked, this study draws on existing data combined with simple field geology and petrographic analysis to drop down to the common denominator of both of these interacting spheres: clay. The result is a reconstructed landscape interpretation that is no longer at odds either with observed patterns of clay use or broader subsistence practice. The role of clay at Çatalhöyük is re-examined in this more appropriate landscape context to demonstrate a fuller and more complex picture than previously thought. While changing clay use seems to directly reflect past decision making, complex and often hidden feedback between the tell and the immediate landscape was often the real driver for change.

While non-technological distractions are a significant concern, this thesis focuses on technological activities that have a unique technology-based risk of distraction as well as present a unique possibility for solutions both through technological safe-guards and legal interventions. The activities of focus in this thesis include talking or texting on a mobile phone (both hand-held and hands-free), using a GPS device (in-vehicle and nomadic), and performing like tasks - including emailing and watching videos on fixed in-vehicle devices. The thesis explores the problem of distracted driving through an expensive literature review of the risks involved. This technical understanding lays a foundation for examining the legal response to technological distractions in the vehicle (both from in-vehicle technology and nomadic devices). The thesis explores the legislative landscape in non-U.S. jurisdictions (for example, the UK, the Netherlands, Sweden, Australia, Canada, France), the legislative landscape in U.S. jurisdictions, and state-imposed product liability and failure to warn in the U.S. It also puts forward the existing and possible educational and technological interventions which can complement legal interventions to effectively promote a change in driver behavior and ultimately safer roads. We conclude that the legal system nationally and internationally is not yet up to the challenge that the emerging technology portends.<br>by Natharat Mongkolsinh.<br>S.M. in Technology and Policy<br>S.M.inTechnologyandPolicy Massachusetts Institute of Technology, School of Engineering, Institute for Data, Systems, and Society

Thesis (Ph. D.)--Harvard-MIT Program in Health Sciences and Technology, 2012.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>Temporal and spatial variation of histone methylation is an important factor in mammalian development. Deciphering the details of such epigenetic phenomena has the potential to enrich both stem cell biology and therapeutics, as well as offer insight into various pathologies. While the enzymatic machinery responsible for these transitions is well known, it is their localization to specific genomic regions that controls cell fate, and this has largely remained a mystery. The goal of this thesis was to use an integrative genomics approach to elucidate the role of cis elements in the establishment of repressive chromatin domains. To this effect, we determined the genetic basis for localization of Polycomb repressive complexes (PRCs) in mammalian embryonic stem (ES) cells. First, by generating genomewide chromatin state maps in mouse and human by high throughput sequencing, we utilized a comparative and motif dictionary approach to computationally identify potential Polycomb recruitment elements. Surprisingly, we found that PRC recruitment is best explained by localization to clusters of unmethylated CpG dinucleotides, elements originally associated with gene activation. Next, in a series of transgenic assays involving human and E. coli sequence, we were able to reconstitute the chromatin state of an epigenetic memory element in mouse ES cells. Finally, we found that as somatic identity is reset during induced pluripotent stem (iPS) cell reprogramming, these same elements are central to a coordinated response in which active chromatin domains are established prior to and independently of transcription. Taken together, these studies highlight the role of a particular cis element in the establishment of both active and repressive chromatin domains. Furthermore, this dynamic underscores how a static genetic element can be utilized to enable the chromatin-based plasticity required of stem cell differentiation and lineage specification.<br>by Richard Patrick Koche.<br>Ph.D.

Many organizations claim to be playing a role in improving Internet security. If anything, the space of security-related institutions seems on first inspection to be over-populated, yet poor security persists. This work proposes a framework to understand the role different institutions play in cyber security. The analysis gives insights into the broad institutional ecosystem of public, private and international actors, and the varied nature of these institutions, their interests, incentives, and contributions to cyber security from hardware, software, protocols, standards and regulation. Based on natural language clustering algorithms, this framework classifies institutions along five dimensions: the aspect of cyber security the institution covers (e.g. network security, cybercrime), the industry and activity sector of the institution (e.g. telecommunications, software and service providers), whether it is part of a specific jurisdiction (e.g. US, Europe), specific institution's characteristics such as its working mode (e.g. forum, information sharing) or primary focus (e.g. economic development, consumer trust), and the governance type (for-profit, not-for-profit, government or international organization). We developed a dataset of approximately 120 institutions that claim a role with respect to cyber security, and using the framework, we identify areas of competing and overlapping institutional interest, relevant areas out of scope of current institutions and dysfunctionalities that hinder overall security improvement.<br>by Cecilia Andrea Testart Pacheco.<br>S.M.<br>S.M. in Technology and Policy

Full textAbstract:
Researchers are presently developing information visualization technologies, with one of their primary purposes being the assisting of educators in the teaching of students.
This thesis examines whether this technology affects student learning and attitudes toward the learning experience.
By presenting information to students using visualization technologies, the hypothesis was tested that learning would be facilitated and that attitudes would be affected positively.
Students were asked to participate in a visualization exercise in which they experienced topographic maps presented in an animated digital medium.
Some students observed the maps displayed on a computer monitor, or projected on a traditional movie-screen, while other students were involved in a virtual reality presentation through the I-Desk (single-wall CAVE), as well as the CAVE itself.
From these results, a gauge of student reaction to the use of this technology was developed.
In particular, it was discovered that students did learn to recognize plan view contour signatures after viewing 3-dimensional visualizations.
In addition, students also reacted positively on a variety of attitude measures.
Because of weaknesses in the research design these results cannot be generalized to the larger population of students.
However, this information could be useful to researchers interested in further examining this field of study, as well as to instructors who wish to incorporate such visualization technology into their own teaching curriculums.<br>Master of Landscape Architecture

Full textAbstract:
Global proven and speculative natural gas reserves are enormous.
Unfortunately, much of these reserves is economically stranded and as a result,
can not be profitably utilized using traditional methods. In another development,
crude oil refiners are facing increasing pressures to produce clean fuels.
Environmentalists are asking for such clean fuels that will force refiners to make
outrageously high refinery-modification investments.
Fischer- Tropsch Gas-to-Liquids (F-T GTL) technology may offer a sustainable
solution to these challenges. On one hand, F-T GTL promises to economically
monetize stranded natural gas reserves. On the other hand, F-T GTL is capable
of producing fuels with qualities that surpass the most stringent current and
future clean-fuel requirements.
A competitive landscape is thus formed: gas utilization options on one side;
automobile fuel production on the other side; and F-T GTL in the centre. The
question is: how competitive is F-T GTL in this landscape?
In response, I developed a real-time economic model using (amongst others) the
Monte Carlo Method. The model captures the competitive landscape as defined,
and compares the viability of competitors in the landscape, using different
scenario settings.
In the study I present a ranking of the competing options in the landscape
in descending order of viability, based on the relative sizes of their NPVs as
estimated for each baseline scenario. Finally, I interpret the rankings.
Based on the outcome of this research, the answer to the question of whether
the current interest in F-T GTL will be sustained or not is an emphatic 'yes'.<br>Thesis (M.Ing. (Development and Management))--North-West University, Potchefstroom Campus, 2007.

Hind, Daniel. "Landscape and technology in the Peak District of Derbyshire : the fifth and fourth millennia B.C." Thesis, University of Sheffield, 2000. http://etheses.whiterose.ac.uk/6037/.
Full textAbstract:
This thesis is concerned with two closely related themes: the inhabitation of the Peak District over the fifth and fourth millennia BC, and the procedures and principles by which we attempt to interpret the durable material traces thereof. A four stage interpretative framework is outlined. Social life is understood through its materiality. The engagement of the self with others is constrained and enabled by that materiality. Archaeologists can represent that process through a textual model. Analogical reasoning mediates each stage and must be made explicit. The Mesolithic and Neolithic, analytical objects constructed through conceptual metaphors, fail to express time and the materiality of practice as mutually constitutive. An integrated theory of landscape and technology is proposed whereby artefacts are understood in terms of relational metaphors, situating them in practice and capturing both their materiality and temporality. Prior research in the study area is critiqued on the basis that the historically specific material conditions therein cannot support models transposed from other regional contexts. A methodology for collection and analysis is developed which privileges those specific conditions in the interpretation of prehistoric technology. Artefact assemblages, it is argued, offer us no unmediated access to prehistoric settlement. No immediate functional equivalence between aggregations similar in composition should be expected. The analysis of stone tools and waste must be integrated with other categories of evidence and interpreted in terms of the potentials offered by their socio-physical context. Original data are analysed in terms of assemblage density, raw material and technological composition, chronological patterning and landscape situation. Integration into the regional corpus, through an explicitly multi-scalar approach, attends to the constitution of social life through practice and developing tradition. The role ascribed to early `monuments' by other archaeologists is particularly brought into question, with respect to the model of relational practice maintained throughout the dissertation.

Full textAbstract:
The Channel Plain Region, now largely submerged by high sea-level, incorporates the UK Crown dependencies of the Channel Islands, Northern France (specifically Brittany and Normandy), and southern Britain. La Cotte de St Brelade sits within this landscape, and is pivotal in understanding the Early Middle Palaeolithic Neanderthal occupations of the area. This research presents a series of new palaeogeographic models, new analysis of the lithic assemblages of the lower, Saalian deposits at La Cotte, and chronostratigraphic and technological relationship(s) across the region. This includes sites such as Piégu, Menez-Dregan, Grainfollet and Les Gastines. Overall, this provides an up-to-date synthesis of Neanderthal behaviour between c. 220 – 160 kya within North Western Europe. Specifically, continuities and changes in behaviour over the period in question are highlighted, including changes in lithic acquisition practices related to climate and landscape changes. Finally, this research adds to the recent re-analysis of the upper “bone heap” assemblages (Pope et al. 2012; Scott et al. 2014; Smith 2015; Shaw et al. 2016), within the later Saalian (>160 kya), and the upper Weichselian deposits (Wragg Sykes 2011; Bates et al. 2013; Scott et al. 2014; Shaw et al. 2016), at La Cotte de St. Brelade.

Full textAbstract:
This dissertation analyses the social, cultural, and material construction of the landscape observer in the United States in mid-nineteenth century. Based on the aesthetic ideal of a perfect union between technology and nature, the reception of landscape entailed the notion of the artist/observer as a hybrid figure that comprised the human and the machine. This quasi-mechanical gaze, individual and corporate at the same time, played a determining role in the construction and diffusion of a nationalist model of democratic spectatorship embedded within pastoral ideology. In this cultural climate, the photographic apparatus, defined by Oliver Wendell Holmes as a ‘mirror with a memory,’ was adopted as a model for the landscape observer. Contrary to previous studies on the relationship among vision, technology, and modernity, in which modern visuality is considered as an abstract, totalizing, and homogeneous phenomenon based on a francocentric model, this dissertation emphasizes the ‘plurality’ of modern vision by situating visual practices and technologies within their specific local and material contexts. First, I discuss how the nineteenth-century enthusiasm for technology shaped the representation and reception of landscape within the visual arts, constituting the American spectator as a performative and collective cohabitation of the visual and the political. The analysis moves on to show how ‘high’ and popular culture embraced the model of the ‘mirror with a memory.’ Transforming landscape experience into a personal and collective ritual of nation formation, this model informed the paintings hanging in the homes of the élites, the large canvases by famous artists shown to the wide public as ‘Great Pictures Exhibitions,’ panorama and diorama spectacles, stereoscopic photography. Lastly, I investigate the relationships among scientific culture, survey photography, and landscape painting. Rather than questioning photography’s ‘artisticity,’ I look at the commercial and debased manifestations of painting and their relation with popular culture at the time of industrialization, media explosion, and the commodification of images.

Full textAbstract:
<p> Practitioner Inquiry provided the framework for teachers (participants) and the teacher as researcher to work collaboratively engaging in a continuous process of planning lessons, reflecting on practice, systematically collecting data, and problem solving as they integrated technology within literacy curriculum. Three teachers (Trio Group) met weekly to discover how teachers learn about literacy technology integration, how they apply this in their classroom instruction, and how they share their ideas about literacy/technology integration with other teachers. These teachers shared their learning with a larger group of teachers (Technology Team) who then hosted a professional development session for the entire faculty to teach them how to integrate technology within instructional practice. Data was gathered from faculty surveys, lesson plans, the Trio Group’s blog posts, videotaped collaboration, audio recordings of all meetings, researcher’s field journal, and the final reflections of faculty. Data was analyzed using “in vivo coding” (Saldana, 2009), looking at each data source independently, and then creating larger categories that led to a descriptive view of the data in themes. Key findings that positively impacted teachers’ ability to learn how to integrate technology were: acknowledging teachers’ perceptions, providing time for collaboration with colleagues, application of practice, scaffolding the learning, and job embedded reflection. Implications include considering a broader view of literacy, technology, and instructional knowledge to include digital literacy and the TPACK framework (Kohler & Mishra, 2009). Implications also include re-envisioning the roles of educators as well as traditional professional development. Collaborative Inquiry Circles were suggested as an alternative to the traditional methods of professional development that could lead to meaningful and sustainable learning opportunities for teachers.</p>

Full textAbstract:
This thesis represents the first investigation to examine Lower and Middle Palaeolithic technological behaviour in Syria in its wider landscape context, focussing on material from the two main river valleys; the Orontes and the Euphrates. Recent geological work has begun to develop an increasingly secure dating scheme for the terraces of these rivers, and hence for the artefacts obtained from them. Key artefact collections which can be located within these emergent chronostratigraphic frameworks were delimited. These assemblages have been analysed using a dynamic and flexible methodology which enabled the specific factors which affect artefact variability (in terms of local material affordances and human choice) to be assessed. Lithic artefacts are treated as the residues of hominin action, and not, as has frequently been the case, the static markers of chrono-cultural evolution. This research has demonstrated that Lower and Middle Palaeolithic hominins responded knowledgably and flexibly to the specific material constraints of particular places at particular points in time. Moreover, it emphasises that understanding particular assemblages entails relocating this material within its landscape context - effectively, looking from lithic artefacts and scatters to reconstructing early human lifeways. Significant outcomes of this research include the identification of the earliest evidence for a hominin presence in Syria (~1 mya), the technological repertoires associated with these populations, the nature of, and the factors responsible for. Lower and Middle Palaeolithic technological variability, and the behaviours associated with Lower and Middle Palaeolithic hominins. The results of the research have wide-ranging and profound implications for understanding the earlier Palaeolithic record of Syria and the wider Near East. In particular, it demonstrates that many fundamental assumptions regarding the nature and meaning of technological and behavioural variability in the Near East require re-assessing.

Full textAbstract:
Thesis (DTech (Information Technology))--Cape Peninsula University of Technology, 2011.<br>This thesis is based on an analysis of the position of mobile learning within learning
and instructional design theories in Higher Education. It seeks to understand the
concept of mobile education or mobile learning, the technology of mobile learning and
its interactions with other media of learning. It also aims to unlock the relationship
between the learning theory and mobile learning as well as the position of mobile
learning, handheld and wireless technologies at universities.
The research design, approach, methodology and methods of this study were framed
around the qualitative grounded theory. This approach guided the process of
collecting and analysing data as well as the discussion of key findings. The data was
gleaned from personal interviews and analysis of literature. The analysis of the data
focused on the social, economic, ideological and technological dynamics and the way
they have shaped the complex landscape of mobile learning in higher institutions of
learning. It also concentrated on the recurrent paradigm shifts and changes and their
implications for teaching and learning in higher institutions.
The analysis of data uncovered several issues that are pertinent to our understanding
of mobile learning. For example, it revealed that mobile learning is not about the
mobile technology but rather about the learner and the learning experience, with the
media playing the role of an instrument for mobilising learning and instruction. It also
led us to the conception that mobile learning has the potential to promote outdoor
learning. This is because this type of technology provides learners with information
that they need about their learning context. Finally it was evident from data that
learning was moving away from process to an institutional social phenomenon. It has
acquired asocial institutional meaning in conceptions such as the learning society and
organisation as well as lifelong and ubiquitous learning.
In this light, this study concludes that integrating classroom-based learning with
informal mobile learning can add value to formal classroom-based learning and it can
also enhance learners' overall learning experience. Moreover, although the concept
of learning space is not restricted to online learning, it is likely to create new learning
spaces. The project also concludes that mobile learning resonates with the learning
and instructional design theories such as the associative, constructive and situated
learning theory.

Full textAbstract:
Considering that technology is developing at a rapid pace, the venture capital landscape changes due to R&D and product maturity life cycles shortening dramatically compared to 50 years ago, thus impacting the portfolio of a VC and its future investment opportunities. However, this relationship between digitalization and venture capital remains underexamined in literature. The research problem is thus to explore how venture capital and the industries it backs have been shaped by digitalization and thus deep tech within the context of Europe. The literature review as a method is examining mechanisms propelled by the digitalization behind the top five VC-backed industries between 2015- 2019 in Europe. In this research, deep tech is a major factor as to why industries have been the most heavily invested in due to their predicted potential exploiting the use of digital technologies. Further research should explore this relationship deeper through obtaining primary data with a quantitative approach to strengthen the implications of the findings.<br>Med tanke på att tekniken utvecklas i snabb takt förändras riskkapitallandskapet på grund av FoU och produktmognadets livscykler som förkortas dramatiskt jämfört med för 50 år sedan, vilket påverkar portföljen för en VC och dess framtida investeringsmöjligheter. Detta förhållande mellan digitalisering och riskkapital förblir emellertid inte undersökt i litteraturen. Forskningsproblemet är alltså att undersöka hur riskkapital och de industrier det stöder har formats av digitalisering och därmed djup teknik inom Europa. Litteraturöversynen som metod undersöker mekanismer som drivs av digitaliseringen bakom de fem främsta VC-stödda industrierna mellan 2015-2019 i Europa. I denna forskning är djup teknik en viktig faktor för varför industrier har varit de mest investerade i på grund av deras förutsagda potentiella utnyttjande av digital teknik. Ytterligare forskning bör undersöka detta förhållande för djupare förståelse genom insamlad primärdata och en kvantitativ metodik för att stärka konsekvenserna av resultaten.

Full textAbstract:
This master’s thesis expands the field of research in interactive playgrounds by examining the role of the built environment that is augmented with digital technology for richer interaction possibilities in such playgrounds. Based on a literature study, this thesis distinguishes interactive play environments from interactive playgrounds, since these often do not reflect the impact of the environment on play very well. The research question being raised is then as follows: “How do children use the digitally augmented built environment in their play?” The thesis describes the process of designing and prototyping an interactive play environment that features communication and a tube to throw objects through as play concepts. Six different prototypes shape the interactive environment in close interplay with landscape and existing built environment. The prototyped environment is then evaluated in a 4-day study at a Swedish school with approximately 240 children during their recess times. This study uses observation as the predominant data gathering method. The gathered data are analyzed based on content analysis. As an answer to the research question, this thesis describes the play that happens in an interactive play environment and draws conclusions on the influence of such an environment on play. The results of the study indicate, that the digitally augmented built environment has an impact on play in stimulating certain new play patterns. It shows its potential mainly as a mediator between the children and the environment, thus stimulating children to explore their environment through play and discover dormant values of the environment. Although we found that the digitally augmented built environment influences play, this study can not confirm that the digital components embedded in the built environment actually improve the play. However, the increasing presence of digital technology in society in general makes it inevitable to think about how this presence should be reflected in children’s playgrounds in the future and this work can give some directions for that.

Business Administration/Interdisciplinary<br>D.B.A.<br>The 2015 mandate of Europay MasterCard and Visa (EMV) “chip card” technology in the U.S. left the payments market primed for the adoption of alternative technologies. The goal of this study is to determine the factors that contribute to the adoption of new, alternative payment technologies by integrating the Technology Acceptance Model (TAM) and Switching Cost Theory and operationalizing both theories in a consumer context. Through a survey of 210 chip card and mobile payment users, this study finds the TAM dimensions of self-efficacy, perceived usefulness, and social influence are key determinants of a user’s propensity to use a new technology in a mandated consumer context and introduces switching costs as an important antecedent to a consumer’s likelihood to use an alternative payment technology. More generally, this work integrates those theories to gain insight into how industry mandates influence user behavior with regards to consumer acceptance of alternative technologies.<br>Temple University--Theses

L’Hétérogénéité cellulaire et les expressions génétiques fluctuantes dans un microenvironnement spécifique restent mal comprises. Ainsi, afin d’apporter un début de réponse à toutes ces questions, beaucoup de paradigmes scientifiques ont été développés, permettant de toujours repousser plus loin les limites du possible. Ainsi, l'objectif de ce premier projet de thèse fut de développer une méthode innovante pour l'analyse épigénétique multiplexée de cellules à une résolution cellulaire unique. En reliant la protéine transposon Tn5 à des anticorps ciblant des facteurs épigénétiques clés, il pourrait être possible d'identifier le site de liaison de facteurs de transcription spécifiques à l'échelle du génome. Néanmoins, en raison de la relative concurrence dans le développement d’une nouvelle technologie dans ce domaine, cet outil très prometteur fut breveté par une autre entreprise et ce projet de thèse a donc été interrompu au profit d’un autre projet dans cette même thématique. Ainsi, beaucoup de progrès importants en biologie sont fortement corrélés avec de nouvelles méthodologies toujours plus innovantes et qui permettent de définir le destin cellulaire au niveau moléculaire. Mais une grande majorité d'entre elles nécessite l'utilisation de procédures destructrices. Pour ces raisons, nous avons développé une nouvelle technologie permettant une analyse transcriptomique dans le temps sans aucune destruction cellulaire. Nommée TRACE pour l'analyse «TRanslatomique» par capture dans des vésicules extracellulaires, elle est caractérisée par l’expression d’un transgène fournissant une translation d'une partie représentative du transcriptome cellulaire à l'intérieur des vésicules extracellulaires. Ainsi, ce «translatome» des cellules qui expriment TRACE peut être suivi dans le temps de manière non destructrice in vitro et in vivo, ce qui est un outil puissant pour de nombreux domaines de recherches fondamentale et translationnelle<br>Cell heterogeneity and fluctuant genetic expression in specific microenvironments remain poorly understood. Thus, to address a beginning of answer to all of these general questions, a lot of new scientific paradigms were developed and enable to push the limits of the possible. Thus, the goal of this first thesis project was to develop a highly innovative method for multiplexed epigenetic analysis of cells at a single cell resolution. By linking the Tn5 transposon protein with antibodies targeting key epigenetic factors, it could be possible to identify the binding site of specific transcription factors at a genome wide level. Nevertheless, due to the relative competition to develop a new technology in the field, this very promising tool has been patented by another company, thus the decision was taken to abort this project and focus on another one. A lot of progress and discovery in Biology is strongly correlated with new methodologies that provide the ability to define cell fate at molecular level, but a large majority of them require the use of destructive procedures. For these reasons, the second research project was to develop a new technology allowing transcriptomic analysis over time without any cell destruction. Named TRACE for “TRanslatomic” Analysis Captured in Extracellular vesicles, it is characterized by a cell-type specific transgene expression providing a translation of a representative part of the cell transcriptome inside Extracellular vesicles. Thus, “Translatome” of cells which express TRACE can be followed over time by non-destructive manner in vitro as well as in vivo, which is a powerful tool for many fields of fundamental and translational research

Higgins, Ryan H. "Energy Storage in the Golden State: An Analysis of the Regulatory and Economic Landscape." Scholarship @ Claremont, 2014. http://scholarship.claremont.edu/pomona_theses/105.
Full textAbstract:
On October 1st, 2013, a mandate was adopted by the California Public Utilities Commission (CPUC) requiring that 1.325 GW of energy storage capability be installed on the California electricity grid by 2024, through the actions of the state’s three investor-owned utilities. While this is a bold first step towards mandated energy storage in the United States, it may be only the beginning for an energy storage industry in this state. It has been well established that energy storage would prove to be a useful asset on the California electrical grid, but the development of storage capacity past the requirements of the mandate will depend upon whether storage can be made cost-effective. Much of the value that storage creates is a public good: many storage applications allow the grid to operate more efficiently as a whole, but not necessarily in a way that can be monetized by any particular party. As a public good, these systemic benefits of storage capacity will be supplied sub-optimally in the absence of government intervention. The energy storage industry will accordingly be one that is strongly affected by the tides of change in technology, regulation and economics in the California energy market. This report will focus primarily on the intersection of the second two of these factors, largely leaving the technological questions to more well-informed parties while seeking to establish what regulatory and economic considerations might be undertaken to ensure that the road to deployment of appropriate energy storage systems is made as clear as possible so that this technology can reach the socially efficient level on the California electricity grid. It is the aim of this report not to promote a specific technology or even an energy storage industry, but rather to shed some light on the effects that the development of such an industry could have on the California electricity market and the energy use paradigm that governs modern electricity grids worldwide. With the adoption of AB 2514, a grand experiment was set in motion that will benefit the entire world as California tests the uncharted technological, regulatory and economic territories of grid-scale energy storage capacity. It is a time of change in the electricity industry, and energy storage is a potentially transformative technology that could very well enable the shattering of an energy use paradigm that has held the world captive to fossil fuels for over a century.

Full textAbstract:
The thesis is concerned with ways in which tourists’ experiences of learning to dive are mediated by technology, equipment and cultural constructions that are projected through visual media. The empirical chapters take a different theoretical body of literature to demonstrate the extent to which mediation alters human perception. The thesis is informed by research participants who took part in an experimental visual methodology that sought to open up new ways of studying the senses. The empirical chapters cover a consideration of the phasing in and out of attention of equipmental prosthetics for learner divers, a phenomenological study of the reorganisation of the senses underwater, a Bergsonian take on the intersubjective nature of recollection upon encountering material relics at a wreck site. The construction of docile diving bodies are considered, in relation to appropriate ways of moving and thinking about the ocean’s inhabitants, before the final empirical chapter outlines the mediative role of videographic souvenirs, as they polish memories of previous experience and alter relations to place. The thesis concludes by drawing attention to the way in which understandings of underwater space are constructed before, during and after real-time perception of the ocean and its various inhabitants. Consequently, it is noted that underwater experience is both highly subjective and intertextual, being furnished by the associations and atmospheres that each learner diver brings to the encounter and being re-presented to others by means of what each diver takes away.

Full textAbstract:
This dissertation centers on virtuosity as a source of creative genesis, boundary-pushing, and musical debate. Focusing on the careers and works of pianists Oscar Peterson (1925-2007) and Glenn Gould (1932-1982), I examine the role of the virtuoso in twentieth-century music-making, and his encounter with Canadian national identity. Gould and Peterson were contemporaries, and despite their differences - Gould was a white classical musician from Toronto, and Peterson, an African Canadian jazz artist from Montréal - their career paths share points of connection. Using archival material from the Glenn Gould fonds and the Oscar Peterson fonds at Library and Archives Canada, I analyze the work of both figures as sources of musical creativity through musical performance and composition.
The first part of this dissertation demonstrates how Gould's and Peterson's respective performances sparked furor through their contestation of musical boundaries. In the first chapter, my analysis of outtakes from Gould's 1955 recording session of the Goldberg Variations illuminates how his radical musical philosophies emerged from his early recording practices. In chapter two, I examine critiques of Peterson's performance aesthetic from an extensive collection of reviews, and argue that his style of virtuosic jazz allowed him to push back against musical expectations. In the third chapter, I examine the work of Canadian filmmaker Norman McLaren whose experimental animation provided opportunities for partnerships with both musicians; with Peterson in 1949 and with Gould in 1969.
The second part of my dissertation takes the reader outside the realm of performance and demonstrates how Gould and Peterson engaged with landscape through sound composition. The fourth chapter investigates the spatial and sonic interpretation of Canadian locales in Gould's Solitude Trilogy, a series of three experimental radio documentaries. In the final chapter, I unravel the biographical and musical influences in Peterson's multi-movement suite for jazz trio, Canadiana Suite. By studying these iconic virtuosos side-by-side, my dissertation illuminates the significance of the performer in Canada's cultural life in the second half of the twentieth-century and yields a new understanding of how Gould and Peterson exploded expectations in their respective musical communities.<br>Music

Full textAbstract:
The 9th March 2014, there is a clash between the Nazis and feminists around Möllevångstorget, Malmö, where four people knife damage so serious that two of them had life-threatening injuries. Many people were there and witnessed the incident but as a citizen, you will be whitened about what happened following the news reports in the media. The press reports plentiful and follow up event but then there are major differences of opinion about what actually happened and about who is actually responsible for the attack arises many questions from the public. Can you trust what is written in the media? Is journalists and their sources credible?Journalists have long been considered the fourth estate whose task is to examine the other two; the government and the parliament. Previous research suggests that the sources and actors who are given space in traditional media in a way, has power over people's interpretation of reality, a reality that the individual before the new media development has not had the same opportunities to discuss and, or question. With the emergence of new media challenged journalists' exclusive right to disseminate information and news about the present. A platform that challenges journalism is Internet-based interactive community Flashback where the audience itself may influence and create media content.When the journalists no longer have the exclusive right to define an event, who has the power over the media landscape? Who should you trust? This has consequences that are worth studying and analyzing. In our study, we approach the explanation by studying the sources which the writers use when reporting about the merits of the case. In Anders Sahlstrands doctoral thesis "Visible" presented in 2000, he notes that elite sources dominate the news media which gives a misleading picture of the society. The purpose of this study is therefore to study the sources are heard when news is portrayed by a journalist in the traditional media versus when the news is portrayed by a citizen journalist on Flashback Forum to see if there is a difference.To obtain the empirical evidence as the basis for our investigation, we conducted a quantitative content analysis. The material that will be used to conduct the quantitative content analysis consists of two parts; traditional media in the form of four daily2newspapers and a medium which falls within the "new media" for user-generated journalism; Flashback Forum.In summary, we can conclude that the answer to our main question is clear. It is predominantly elite sources which may make its voice heard when news is portrayed in traditional media and it's especially non-elite sources that sounds when a news reported on Flashback Forum. The number of elite sources and non-elite sources differ depending on which media platform is studied and also the manner, how they are heared are different depending on the platform.

This paper seeks to break down how a large scale Electronic Health Records system could improve quality of care and reduce monetary waste in the healthcare system. The paper further explores issues regarding regulations to data exchange and data interoperability. Due to the massive size of healthcare data, the exponential increase in the speed of data generation through innovative technologies, and the complexity of healthcare data types, the widespread of a large-scale EHR system has hit barriers. Much of the data available is unstructured or contained within a singular healthcare provider’s systems. To fully utilize all the data available, methods for making data interoperable and regulations for data exchange to protect and support patients must be made. Through angles addressing data exchange and interoperability, we seek to break down the constraints and issues that EHR systems still face and gain an understanding of the regulatory landscape.

Full textAbstract:
La tristeza degli agrumi, causata da Citrus tristeza virus (CTV) e' uno dei fattori limitanti l'agrumicoltura mondiale. Nonostante il considerevole impegno della ricerca, le informazioni sulla caratterizzazione degli isolati del virus sono limitate ai geni principali. Ancora in fase preliminare sono anche gli studi sull' espressione genica a parte un recente lavoro su piante di lima messicana in risposta a due differenti ceppi di CTV.
Questo studio ha riguardato la risposta fenotipica di indicatrici diverse, dopo inoculazione con un isolato virulento di CTV e le connesse modificazioni dell'espressione genica in arancio amaro, lima messicana, pompelmo Duncan, cedro Etrog e alemow. L'isolato utilizzato e' stato selezionato nel corso di indagini preliminari. Dopo la caratterizzazione con test biologici su piante indicatrici le analisi molecolari hanno permesso di concludere che si tratta di un isolato con un 99% di identita' nucleotidica con alcuni ceppi del Sud America (BaraoB, Val-CB e C271-2), verosimilmente appartenente al biogruppo 4.
Le relazioni che il virus stabilisce con la pianta ospite sono state studiate attraverso una ricerca mirata ad accertare le modificazioni del profilo genico sulle piante sopra indicate inoculate sperimentalmente.
Allo scopo e' stato utilizzanta la tecnica del reverse northern blot con specifiche sonde, la real time e la tecnica espressione differenziale dell' RNA messaggero (DDRT-PCR).
Dopo una prima fase dedicata alla ricerca bibliografica sull' uso di tecniche molecolari per lo studio della modulazione genica in piante di agrumi, con riferimento a stress biotici e abiotici, sono state valutate le differenze tra piante di arancio amaro inoculate con l'isolato di CTV selezionato (SG29) e piante sane mediante reverse Northern blot, utilizzando sonde ricavate da una ricerca sulle infezioni di Citrus exocortis viroid (CEVd) in piante di cedro Etrog. Successivamente mediante real time PCR quantitativa sono stati selezionati sette geni, risultati differenzialmente espressi in arancio amaro, al fine di valutarne la modulazione in cinque specie di agrumi (arancio amaro, lima messicana, cedro, pompelmo e alemow) inoculati con CTV SG29. E' stata infine effettuata l'analisi differenziale dell' RNA messaggero in semenzali di arancio amaro inoculati con CTV SG29.
Le analisi real time PCR hanno messo in evidenza che nei semenzali di arancio amaro, il gene della metallotioneina (MT), il regolatore del sileziamento genico (rgs-CaM) e il gene COSTANS-like, risultavano sovra espressi; di contro l'espressione dell' EREBP e del gene della perossidasi (PRX) mostravano un differente comportamento risultando sotto espressi. I geni codificanti per l'alcool deidrogenasi (ADH) e la permeasi degli amminoacidi, risultavano essere rispettivamente sotto e sovra espressi, mentre i geni per l' ADH e per la PRX, coinvolti nella risposta generale ai fattori di stress, si mostravano sotto espressi in tutti gli ospiti saggiati. Viceversa, rgs-CaM, AP e CLP erano sotto espressi nel cedro Etrog, nel pompelmo e nell'arancio dolce e sovra espressi nell' arancio amaro. La sovra espressione dell' EREBP, era presente solamente nel cedro Etrog e nell' arancio dolce, mentre MT era indotto solo nell'arancio amaro e nell' arancio dolce.
Nella lima messicana, cosi come nei semenzali di arancio amaro, l' infezione di CTV ha indotto la sotto espressione di tutti i geni selezionati eccetto il gene rgs-CaM che risultava drasticamente sovra espresso. Dal momento che entrambi gli ospiti sono suscettibili a CTV SG29 e reagiscono con sintomi molto gravi, si ipotizza che l'azione dell' rgs-CaM come soppressore del silenziamento genico sia specie-specifico e che CTV induca fortemente la sua espressione nelle piante suscettibili, riuscendo ad evadere l'attivita' di silenziamento dell' RNA.
L'analisi differenziale (DDRT-PCR) ha permesso di individuare l' alterazione di altri 4 geni (up e down) a seguito dell'inoculazione con CTV. Due di essi mostrano una elevata omologia di sequenza con 2 diverse sequenze EST di Citrus sinensis la cui funzione risulta pero' sconosciuta, la terza e' altamente omologa ad un retrotrasposone di Arabidopsis thaliana, il cui ruolo in condizioni di stress biotici e abiotici e' largamente riportato in letteratura. L' ultimo trascritto, che risulta invece essere regolato negativamente, codifica per una proteina del citocromo P450.<br>The research concerns one of the most important limiting factor of the citriculture worldwide, the tristeza disease, caused by the Citrus tristeza virus (CTV). Despite the efforts made by the research many informations are still lacking, being available only some data concerning few genes. Still in a preliminary stage are the studies about the gene modulation after the infection, a part a recent paper on the Mexican lime response to infection by two CTV isolates. The study has investigated the phenotypic response of some indicators plants inoculated with a severe isolate of CTV and the gene expression modification connected. In sour orange, mexican lime, Duncan grapefruit, sweet orange and Etrog citron. The CTV isolate was selected during a preliminar survey, characterized with biological tests, as well with molecular analysis. According to the results the isolate has 99% identity with some strains of South America, nomely Barao B, Val-CB and C271-2, likely belonging to biogroup 4.
The relations between CTV and host plants have been investigated thought a study of the gene patterns of inoculated sour orange.
To this aim the reverse Northern blot with specific probes, the real time PCR and the differential display analysis of m-RNA, have been undertaken.
After a critical literature review on the molecular techniques used to study the gene modulation in citrus trees affected by biotic or abiotic stress, the differences between sour orange CTV infected or not, were evaluated by Reverse Northern Blot, using probes obtained in a previous research Etrog citron infected with Citrus exocortis viroide (CEVd).
Seven genes differently expressed in sour orange were selected to evaluate their modulation by reverse transcriptase quantitative real time PCR in five citrus species (sour orange, mexican lime, citron, grapefruit and alemow) inoculated with CTV SG29.
A messenger RNA differential display RT-PCR analysis (DDRT-PCR) of sour orange seedlings inoculated with the viral isolate CTV SG29 in comparison with healthy controls, was also carried out for identifying further differentially expressed.
In sour orange seedlings, quantitative real time PCR revealed that genes codifying for metallothionein (MT), regulator of gene silencingà à à ¢ calmodulin-like protein (rgs-CaM) suppressor of RNA silencing, and CONSTANS-like (CLP) were up regulated, as observed in Northern blot analysis; in contrast, the expression of ethylene-responsive binding protein (EREBP) and peroxidase (PRX) genes showed a different behavior resulting down regulated. Alcohol dehydrogenase (ADH) and aminoacid permease (AP) genes, not detected by Northern, resulted to be down and up regulated, respectively. ADH and PRX genes, involved in general response to stress factors, exhibited the same pattern of expression (down regulation) in all citrus hosts tested. On the contrary, rgs-CaM, AP and CLP were down regulated in Etrog citron, grapefruit and sweet orange and over expressed in sour orange. Up regulation of EREBP occurred only in Etrog citron and in sweet orange, whereas MT is induced only in sour orange and sweet orange. Interestingly, CTV infection in Mexican lime as well as on sour orange seedling induced the down regulation of all the selected genes, but the rgs-CaM was drastically over expressed. Since both hosts are susceptible to CTV S29 and showed very severe symptoms, the hypothesis is advanced that rgs-CaM may act as host specific RNA silencing suppressor and CTV strongly induces its expression in susceptible plants, evading RNA silencing activity.
Four new transcripts were identified in the first fingerprints obtained. Three of them are positive regulated in response to CTV infection, two show high sequence similarity with two different EST of Citrus sinensis, whose biological function is unknown, the third one shows sequence similarity with a retrotransponson of Arabidopsis thaliana, whose role under conditions of biotic and abiotic stress is largely reported in literature. The last transcript, which is negatively regulated, encodes a protein belonging to the family of cytochrome P 450.

Full textAbstract:
Currently, there are indications that Europe is facing an innovation deficit. The main explanation to the lack of innovation is considered to be that new technology-based firms are facing difficulties in receiving funding and consequently do not establish on the market. As new technology-based firms have an important role in technology development and overall growth, a consequence thereof could be a long- lasting negative effect on technological change and economic growth. The venture capital industry is frequently put forward as the actor that can provide financing for these types of firms. This study aimed to investigate the contemporary role that Swedish traditional venture capitalists and government supported venture capitalists have in the funding landscape of new technology-based firms. To fulfill this purpose, the study analyzed both the investors' preferences and the challenges with investing into new technology-based firms. The findings were acquired through performing eight semi- structured interviews with highly knowledgeable practitioners. In addition, literature was scrutinized. The study concluded that the preferences of the venture capital firms are heavily misaligned with investments into new technology and that digital companies present a better aligned investment alternative. More specifically, venture capitalists perceived the teams of new technology-based firms to be lacking, which is misaligned with the venture capitalists' strong emphasis on the team. New technology-based firms were also perceived to be associated with great risks, which is misaligned with the risk aversion of venture capitalists. The high risk was found to be related to the high degree of novelty, the perceived difficulties in finding syndication partners, the venture capitalists' lack of specific knowledge and experience, the long time to market and the large funding need in early stages. Further, the long time to market is ill-suited with the fund structure of traditional venture capital firms. On the other hand, digital companies were found to be well aligned with the venture capitalists' risk profile and preference for investing large amounts of capital at once. When it comes to government-supported venture capitalists, the study concluded that Industrifonden's preferences are similar to those of traditional venture capitalists and that Almi Invest, due to its structure, faces specific barriers for investing. Based on these findings, the conclusion was drawn that the likelihood is low that venture capitalists will invest in new technology-based firms. In order to be able to draw conclusions regarding the impacts on innovation and technological change, further research on the capabilities and preferences of informal venture capital is necessary. Further research could also attend to the demand of financing to increase the understanding of the innovation deficit.<br>Idag finns indikationer på innovationsbrist i Europa. En huvudsaklig orsak till innovationsbristen anses vara att bolag med ny teknologi har svårt att få finansiering och därmed etablera sig på marknaden. Eftersom ny teknologi spelar en viktig roll i teknologisk utveckling och ekonomisk tillväxt, är en möjlig konsekvens av innovationsbristen långtgående negativa effekter på teknologisk utveckling och ekonomisk tillväxt. Venture capital industrin framhålls ofta som en aktör som kan finansiera denna typ av bolag. Denna studie syftade till att undersöka vilken roll svenska traditionella venture capital fonder och statliga venture capital fonder har i finansieringslandskapet av ny teknologi. För att uppnå detta syfte analyserade studien både investerarnas preferenser och utmaningarna med att investera i ny teknologi. Resultaten nåddes genom att genomföra semistrukturerade intervjuer med åtta erfarna praktiserande i industrin. Intervjuobjekten hade antingen erfarenhet från traditionellt eller statligt venture capital. Utöver detta granskades litteratur på området. Studien fann att venture capital industrins preferenser på flera vis inte matchar investeringar i ny teknologi medan digitala bolag väl passar in i preferenserna. Mer specifikt ansåg venture capitalisterna att teamen för ny teknologiska bolag saknar viktiga kvalitéer, något som missmatchar venture capitalisternas starka fokus på teamet. Nyteknologiska bolag ansågs också vara associerade med hög risk, vilket står i stark kontrast till venture capitalisternas riskaversion. Den höga risken ansågs vara relaterad till investeringens nya natur, den upplevda svårigheten att hitta syndikteringspartners, venture capitalisters avsaknad av specifik erfarenhet, den långa tiden till marknaden och de stora kapitalbehoven i tidiga skeden. Vidare fann studien att den långa tiden till marknaden var misspassat till fondstrukturen hos traditionella venture capitalister. Och andra sidan visade studien att digitala bolag passar väl med venture capitalisters riskprofil och preferens för att investera stora belopp på en gång. När det kommer till statliga venture capital fonder fann studien att Industrifondens preferenser är mycket lika de traditionella venture capitalisternas preferenser och att Almi Invest står inför särskilda barriärer för att investera i ny teknologi. Baserat på dessa resultat konkluderade studien att sannolikheten är låg att venture capitalister investerar i ny teknologi. Forskning på kapaciteterna och preferenserna för informellt kapital är dock nödvändigt för att kunna dra slutsatser kring effekterna på innovation och teknisk utveckling. Framtida forskning bör också fokusera på efterfrågan på kapital för att förstå innovationsbristen.

Full textAbstract:
Methodology. In chapter 1, METHODOLOGY, the theoretical and methodological frame of reference is
outlined. In chapter introduction a rapid excursus of the main directions followed by prehistoric
hunter‐gatherers archaeology is provided, with special reference to the informative potential of the
lithic industries. In what follows the main descriptive and interpretive standards adopted in the
analysis of the archeological material are provided.
Analysis. Chapters 3, 4 and 5 are devoted to the analysis, description and interpretation of the lithic
assemblages of the sites of MADONNA DELL’OSPEDALE, FOSSO MERGAONI and GROTTA DI POZZO.
The structure is the same for each chapter. First, a general description of the site is provided
(presentation of the site), along with its geographic localization, the research activities carried out on it
and the chronological and stratigraphic data. The main section of each chapter is represented by the
lithic artefacts technological analysis (lithic production), whose description follows the theoretical
phases of the reduction sequence. Contextually, morpho‐technical and morpho‐metric data are
provided. The conclusive section of each chapter (synthesis and discussion) aims to organize data in a
synthetic and organic frame, as well as to provide a behavioral interpretation of the circumstances
leading to the assemblage formation.
Discussion. Chapter 5, THE EARLY EPIGRAVETTIAN OF THE NORTHERN ADRIATIC FRINGE:
DISCUSSION, aims to put data within the frame of the human frequentation of the northern fringe of
the Adriatic at the end of the LGM, along the borders of the once exposed Great Adriatic Plain. After a
general introduction on the LGM at European scale, the archeological evidence from three study areas
is synthesized: central Apennine (Marche and Abruzzi regions), Berici hills (Venetian region) and
North‐western Balkans (Slovenia, northern Croazia and northern Bosnia).
On the basis of edited data and those from the present work, it has been tried to contribute to the
discussion about whether the Great Adriatic Plain could have represented a favorable environment for
human groups in conditions of climatic worsening. A possible affirmative answer is advanced, because
the supposed borders of such physiographic element bear evidence of contingent brief visits finalized
to resource sacquisition, which implies, at least, the existence of some more stable settlement areas,
somewhere else. Data about mobility strongly point towards an East‐west shifting direction followed
by Epigravettian collectors, which suggests an active role of the once exposed Great Adriatic Plain.

Full textAbstract:
Opportunities in tangible and intangible authentic values in one hand and disruptive threats, on the other, stand on the ultimate level in the Bisotun Cultural Landscape. Research has discoursed that during the last fifty years, the natural-cultural integrity of the site has lost its coherence and connections under the pressing development issues. This study aims to determine how entwined layers of a Narrative Cultural Landscape can be revitalized through comprehensive multi-criteria planning. Three critical questions of this research figure out in Theoretical, Strategical, and Practical Inquiries. Firstly, regarding the different doctrine about the meaning of culture in the Persian language, delving back on several definitions for the cultural landscape term and asks: How can the abstract concept of culture by Persian terminological analysis of this word, define the novel interpretation of the cultural landscape term, which can open new entries in landscape communal values revival? Secondly, to diagnose a holistic, efficient revitalization strategy, it asks How can acupunctural strategy be applied in breathing new life into the Bisotun NCL structures? Finally, based on the innovative technology achievements in the recuperation of the immaterial layers of NCLs, it asks: How can new technologies involve in revitalizing the narrative layers of Bisotun NCL?
In this context, what is considered as Cultural Landscape in this research is a hybrid collection of (I) Natural landscapes, (II) Tangible continuous historical remains, and (III) Literary grand narratives interlocked with the context perpetually. The literature genres hidden in Bisotun NCL are a “gold thread” in the creative reading of this landscape. Investigating and understanding the literary narratives on the one hand cause to explore the clues in recovery the physical layers of CL that are disrupted, and on the other hand, in this changing world, the literature layer bound to the landscape should keep alive and valorized as authentic intangible values.
The role of technology in revitalizing the intangible values of the cultural landscape has also been studied meticulously in this research. Several good practices analyzed to point out the practical recommendations in applying technologies in virtual refurbishing the ruined architecture structures and revitalize the hidden layers of the landscape.
The descriptive-analytic method has applied to codify the principles of revitalization. By collecting data and creating knowledge, quantitative research methods supported and scrupulous literature review followed up. Qualitative method detecting field survey encompasses a detailed description of fieldwork (including the content of opportunities and threats), in-depth field observations, interviews, and filling the questionnaires involving local communities applied to the case study site. The profound research about Bisotun heritage landscape layers has carried out in three zones Natural, Historical, and Narrative. This research applied mixed methodologies as considering the interdisciplinary content of the fields related to the subject.<br>ENGLISH

Master of Landscape Architecture<br>Department of Landscape Architecture/Regional and Community Planning<br>Jessica Canfield<br>Interactive technology is rapidly affecting our society, extending opportunities for convenience,
communication, function, and pleasure. Defined as electronic or computation-based entities
that reciprocate human use or action, interactive technology allows people the opportunity
to personalize how something looks, how it feels, what it does, and how it is perceived. Many
physical objects, such as a home thermostat system or a motion-activated sculpture, are
embedded with computation that allows them to detect certain environmental influences,
and respond with a purposeful action. As suggested by Malcolm McCullough, interactive
technologies will be implemented into the urban environment, grounding them to a specific
place and reflecting the character and context. Interactive technology will be combined with
traditional urban design practices to generate an interactive urban environment.
The Civic Room in Downtown St. Louis is prime for renewal. Underutilized and monotonous, the
park space is seen as a tear in the urban fabric and lacks diverse program opportunities. The
Civic Room will be used as a testing ground for an interactive urban environment, utilizing three
dimensions of interactive technology, including information exchange, creative expression, and
kinetics, as well as the specific elements of an effective urban open space (Whyte, 1980). Then,
the existing site and resulting interactive urban environment will be evaluated on its potential to
improve certain dimensions of performance (Lynch, 1981), and its impact on the identity and
use of the space.
Engaging an interactive urban environment in the St. Louis Civic Room will promote an
understanding of the effects that interactive technology can begin to have in a larger context.
It will activate the space, promote social collaboration, and establish a dynamic atmosphere
that reflects more closely the desired intent of all users. In turn, it can propel the opportunity to
approach interactive urban environments as an alternative method of urban space design.

En la misma se aplicó una metodología que muestra los principales Índices técnico-explicativos del parque de máquinas y tractores de los municipios de Toluca de Lerdo y Metepec. Se pudo encontrar en todos estos datos obtenidos, que los tractores trabajan aproximadamente una media de 353 Moto-horas por ciclo agrícola anual, cantidad muy pequeña para tan alta inversión, por otro lado como media existe un tractor agrícola por cada 4,54 ha de suelo cultivado, lo que conlleva a una elevación de los costos de producción por unidad producida. La relación tractor–implemento es de 4,16 implemento por tractor, cuando los estándares internacionales, tienen una relación de 6:1. Lo planteado anteriormente, es un aviso importante para que los gobiernos, tomen las medidas necesarias en buscar dotar a la agricultura de tractores con potencias adecuadas y una óptima relación implemento tractor que abata costos.<br>UNIVERSIDAD AUTÓNOMA DEL ESTADO DE MÉXICO, SEDAGRO, NEW HOLLAND JOHN DEERE, MASSEY FERGUSON

Full textAbstract:
The Swedish retail sector is experiencing a structural shift, where the e-commerce sector isgrowing steadily each year. As of 2017, e-commerce had seen an average annual growth rateof 14% over the past decade. Currently, e-commerce corresponds to 8.7% of the total retailsector. As the e-commerce sector is growing, so are the requirements for the underlyinglogistics operations. Larger trade volumes implicate a greater need of warehouses andlogistics real estate.The purpose of this master thesis is to investigate how the changing retail landscape will affectdemand for logistics real estate in Sweden for the coming decade. The study is based on amixed-method research design, combining a data analysis on the current market situationwith scenario-based interviews with 14 professionals about future market expectations. Thisthesis is structured around the DAS-framework, a strategy model developed at the Real Estateand Housing department at Delft University of Technology in the Netherlands.From observations, the conclusion is that the logistics real estate stock in Sweden needs to becomplemented by several, smaller distribution terminals located in close vicinity to the citycores. This in order to address the last-mile issue from the continued development of ecommercein areas with dense population.<br>Den svenska handelssektorn genomgår ett strukturellt skifte, där e-handelssektorn växerstadigt varje år. Under det senaste decenniet har e-handelssektorn i genomsnitt haft en årligtillväxt om 14% och utgör per 2017 8,7% av den totala detaljhandeln. I takt med att ehandelssektornväxer sig större ökar också krav på lager- och logistikfastigheter. Störrehandelsvolymer innebär ett större behov av lager- och logistikyta.Syftet med denna masteruppsats är att undersöka hur e-handelns utveckling kommer attpåverka efterfrågan inom logistiksektorn på den framtida svenska fastighetsmarknaden.Studien baseras på en blandad forskningsmetod, dels genom en data-analys av den nuvarandesituationen inom logistiksektorn, och dels genom scenario-baserade intervjuer med 14professionella aktörer om framtida marknadsförväntningar. Uppsatsen är strukturerad efterDAS-framework, en strategisk modell utvecklad av fastighetsavdelningen på Delfts TekniskaUniversitet i Nederländerna.Det som kunnat observeras är att det finns ett framtida behov av att komplimentera detsvenska utbudet av logistikfastigheter med flera, mindre distributionsterminaler i stadsnäralägen. Detta för att försöka lösa den rådande ”sista-mil” distributionsproblematik som en ökade-handel skulle innebära, tillsammans med en högre befolkningstäthet i stadsområden.

Full textAbstract:
This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features. In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx. 90 m resolution) grid for approximately 80 % of Earth’s land surface. The X-band SRTM data were processed with a 1 arc second (approx. 30 m resolution) grid by the German space agency, DLR and the Italian space agency ASI, but due to the smaller X-SAR ground swath, large areas are not covered. The latest version 3.0 SRTM/C DEM and SRTM/X band DEM were re-projected to 90 and 30 m UTM grid and used to generate morphometric parameters of first order (slope) and second order (cross-sectional curvature, maximum curvatures and minimum curvature) by using a bivariate quadratic surface. The morphometric parameters are then used in a SOM to identify morphometric features (or landform elements) e.g. planar, channel, ridge in mountainous areas or yardangs (ridge) and corridors (valley) in hyper-arid areas. Geomorphic phenomena and features are scale-dependent and the characteristics of features vary when measured over different spatial extents or different spatial resolution. Morphometric parameters were derived for nine window sizes of the 90 m DEM ranging from 5 × 5 to 55 ×55. Analysis of the SOM output represents landform entities with ground areas from 450 m to 4950 m that is local to regional scale features. Effect of two SRTM resolutions, C and X bands is studied on morphometric feature identification. The difference change analysis revealed the quantity of resolution dependency of morphometric features. Increasing the DEM spatial resolution from 90 to 30 m (corresponding to X band) by interpolation resulted in a significant improvement of terrain derivatives and morphometric feature identification. Integration of morphometric parameters with climate data (e.g. Sum of active temperature above 10 ° C) in SOM resulted in delineation of morphologically homogenous discrete geo-ecological units. These units were reclassified to produce a Potential Natural Vegetation map. Finally, we combined morphometric parameters and remotely sensed spectral data from Landsat ETM+ to identify and characterize landscape elements. The single integrated data set of geo-ecosystems shows the spatial distribution of geomorphic, climatic and biotic/cultural properties in the Eastern Carpathians. The results demonstrate that a SOM is a very efficient tool to analyze geo-morphometric features under diverse environmental conditions and at different scales and resolution. Finer resolution and decreasing window size reveals information that is more detailed while increasing window size and coarser resolution emphasizes more regional patterns. It was also successfully applied to integrate climatic, morphometric parameters and Landsat ETM+ data for landscape analysis. Despite the stochastic nature of SOM, the results are not sensitive to randomization of initial weight vectors if many iterations are used. This procedure is reproducible with consistent results.<br>Avhandlingen presenterar en halvautomatisk metod för att analysera morfometriska kännetecken och landskapselement som bygger på Self Organizing Map (SOM), en oövervakad Artificiell Neural Nätverk algoritm, i två helt skilda miljöer: 1) Man and Biosphere Reserve "Eastern Carpathians" (Centraleuropa) som är ett komplext, bergigt och humid område och 2) Lut öken, Iran, en extrem torr region som kännetecknas av återkommande vinderoderade objekt. Basen för undersökningen är det C-band SRTM digital höjd modell (DEM) med 3 bågsekunder rutnät som National Aeronautics and Space Administration släppte 2003 för ungefär 80 % av jordens yta. Dessutom används i ett mindre område X-band SRTM DEM med 1 bågsekund rutnät av den tyska rymdagenturen DLR. DEM transformerades till 90 och 30 m UTM nätet och därav genererades morfometriska parametrar av första (lutning) och andra ordning (tvärsnittböjning, största och minsta böjning). De morfometriska parametrar används sedan i en SOM för att identifiera morfometriska objekt (eller landform element) t.ex. plan yta, kanal, kam i bergsområden eller yardangs (kam) och korridorer (dalgångar) i extrem torra områden. Geomorfiska fenomen och objekt är skalberoende och kännetecken varierar med geografiska områden och upplösning. Morfometriska parametrar har härletts från 90 m DEM för nio fönsterstorlekar från 5 × 5 till 55 × 55. Resultaten representerar landform enheter för områden från 450 m till 4950 m på marken dvs. lokal till regional skala. Inflytande av två SRTM upplösningar i C och X-banden har studerats för identifikation av morfometriska objekt. Förändringsanalys visade storleken av upplösningsberoende av morfometriska objekt. Ökning av DEM upplösningen från 90 till 30 m (motsvarande X-bandet) genom interpolation resulterade i en betydande förbättring av terräng parametrar och identifiering av morfometriska objekt. Integration av morfometriska parametrar med klimatdata (t.ex. summan av aktiv temperatur över 10° C) i SOM resulterade i avgränsningen av homogena geoekologiska enheter. Dessa enheter ha används för att producera en karta av potentiell naturlig vegetation. Slutligen har vi kombinerat morfometriska parametrar och multispektrala fjärranalysdata från Landsat ETM för att identifiera och karaktärisera landskapselement. Dessa integrerade ekosystem data visar den geografiska fördelningen av morfometriska, klimatologiska och biotiska/kulturella egenskaper i östra Karpaterna. Resultaten visar att SOM är ett mycket effektivt verktyg för att analysera geomorfometriska egenskaper under skilda miljöförhållanden, i olika skalor och upplösningar. Finare upplösning och minskad fönsterstorlek visar information som är mer detaljerad. Ökad fönsterstorlek och grövre upplösning betonar mer regionala mönster. Det var också mycket framgångsrikt att integrera klimatiska och morfometriska parametrar med Landsat ETM data för landskapsanalys. Trots den stokastiska natur av SOM, är resultaten inte känsliga för slumpvisa värden i de ursprungliga viktvektorerna när många iterationer används. Detta förfarande är reproducerbart med bestående resultat.<br>QC 20100924
