Pełny tekst źródłaNowadays datasets with non-standard structures are more and more common. Examples include the already well-known multi-task framework where each data sample is associated with multiple output labels, as well as the multi-view learning paradigm, in which each data sample can be seen to contain numerous descriptions. To obtain a good performance in tasks like these, it is important to model the interactions present in the views or output variables well.Kernel methods offer a justified and elegant way to solve many machine learning problems. Operator-valued kernels, which generalize the well-known scalar-valued kernels, have gained attention recently as a way to learn vector-valued functions. The choice of a good kernel function plays crucial role for the success on the learning task.This thesis offers kernel learning as a solution for various machine learning problems. Chapters two and three investigate learning the data interactions with multi-view data. In the first of these, the focus is in supervised inductive learning and the interactions are modeled with operator-valued kernels. Chapter three tackles multi-view data and kernel learning in unsupervised context and proposes a scalar-valued kernel learning method for completing missing data in kernel matrices of a multi-view problem. In the last chapter we turn from multi-view to multi-output learning, and return to the supervised inductive learning paradigm. We propose a method for learning inseparable operator-valued kernels that model interactions between inputs and multiple output variables

Pełny tekst źródłaEn un intento por mejorar la eficiencia y la equidad de los sistemas educativos, un número creciente de sistemas educativos han adoptado políticas de rendición de cuentas (RdC) basadas en el desempeño escolar. Si bien la investigación sobre las reformas de RdC se ha expandido en las últimas décadas, la literatura existente no aborda en profundidad los motivos por los que los decisores de políticas, en contextos tan diversos, optan por la RdC basada en el rendimiento a la hora de reformar sus sistemas educativos. De manera similar, la comprensión de los mecanismos y condiciones bajo los cuales la RdC genera resultados diferenciados es todavía limitada. Con el objetivo de contribuir a llenar estos vacíos en la literatura existente, esta tesis doctoral adopta una aproximación multiescalar al estudio del despliegue de las políticas de RdC basadas en el desempeño en Noruega, un país nórdico anteriormente considerado ""inmune"" a este fenómeno de política globalizadora. Concretamente, la tesis explora cómo la RdC basada en el desempeño se adopta, configura e implementa en el sistema educativo noruego. Para examinar la trayectoria de la RdC en Noruega, el análisis se basa en dos fuentes de datos principales; 37 entrevistas en profundidad con políticos de alto rango, decisores de políticas y agentes clave de la educación noruega, así como 4 libros blancos. Además, para ilustrar el papel desempeñado por organizaciones que intermedian en las formas en que la RdC se desarrolla y recontextualiza en el ámbito de la práctica educativa, se realiza un análisis sistemático de 3.046 artículos de prensa publicados por 155 periódicos regionales y locales noruegos entre 2004-2018. Finalmente, para obtener una comprensión más profunda de cómo se interpretan y ponen en práctica las demandas de RdC a nivel escolar, el análisis se basa en entrevistas en profundidad a 23 directores que trabajan en escuelas primarias. Los resultados destacan que, en Noruega, la RdC se ha adoptado e institucionalizado como una forma de asegurar los estándares de aprendizaje en un sistema educativo altamente descentralizado. Si bien los factores y las ideas de políticas globales han influido claramente en los procesos de diseño de la política, la trayectoria de la RdC en Noruega está determinada simultáneamente por las instituciones políticas, el régimen de bienestar y el sistema educativo del país, así como por los procesos de implementación de políticas. Los medios de comunicación juegan un rol central en la mediación del impacto de la publicación de los resultados de las pruebas de desempeño como un mecanismo de presión clave para provocar el cambio de comportamiento deseado entre las escuelas. El análisis identifica cuatro marcos de significado dominantes en la cobertura de los medios regionales y locales sobre las pruebas estandarizadas, así como importantes diferencias en la información de los medios sobre desempeño escolar a lo largo del tiempo y entre las diferentes localidades. Finalmente, los resultados identifican patrones de respuesta distintos en la forma en que los directores noruegos perciben, interpretan y traducen las demandas de RdC. La tesis pone de relieve que la RdC basada en el desempeño promueve cambios de comportamiento a través de la reformulación de las normas y nociones sobre buenas prácticas educativas y de cómo los educadores dan sentido a los aspectos centrales de su trabajo. Al hacerlo esta tesis desafía una premisa central de la investigación sobre la RdC educativa; es decir, que los incentivos extrínsecos y las sanciones son los principales factores explicativos del cambio de comportamiento impulsado por la RdC. Además, la tesis contribuye a la literatura sobre la RdC educativa al demostrar el valor de un enfoque multiescalar para comprender el despliegue de políticas de RdC.
“In an attempt to raise the performance, efficiency and equity of education systems, performance-based accountability policies have been adopted or strengthened by an increasing number of countries, characterized by highly diverse political institutional regimes, education systems, and levels of economic development. While research interest in accountability reforms has sparked in recent decades, the existing literature remains characterized by an insufficient understanding of why policymakers, in such diverse contexts, turn towards performance-based accountability to reform their education systems, in particular considering the absence of strong evidence regarding the benefits produced by this reform approach. In a similar vein, a limited understanding prevails of the mechanisms and conditions under which performance-based accountability generates particular policy outcomes. With the aim of contributing to filling some of the gaps in the existing literature, this doctoral dissertation adopts a multi-scalar case-study, which scrutinizes the different (but interconnected) scales in the deployment of performance-based accountability policies in Norway, a Nordic country formerly considered ‘immune’ to this globalizing policy phenomenon. More specifically, the dissertation examines how performance-based accountability, as a global policy for education reform, is adopted, shaped and enacted in the Norwegian education system. In order to examine the trajectory of performance-based accountability in Norway, the analysis relies on two principal data sources; 37 in-depth interviews with top-level politicians, policymakers and education stakeholders, as well as 4 White Papers. Moreover, to shed light on the role played by intermediate bodies in mediating the ways in which accountability plays out in practice, a systematic analysis of 3,046 newspaper articles published by 155 Norwegian regional and local newspapers between 2004-2018 is performed. Finally, to gain a deeper understanding of how accountability demands are interpreted, experienced and put into practice at the school level, the analysis relies on in-depth interviews with 23 school principals working at public, primary schools in nine urban municipalities. The findings highlight how performance-based accountability has been adopted and institutionalized in Norway as a way to secure equity and quality standards in a highly decentralized education system. While global drivers and policy ideas have clearly influenced policy design processes, the trajectory of performance-based accountability in Norway is simultaneously shaped by the country’s political institutions, welfare regime, and education system, as well as by policy enactment processes. The media play a key role in mediating the impact of the publication of test results as a key pressure mechanism to elicit the desired behavioral change. The analysis identifies four dominant frames present in regional and local media coverage on standardized testing, as well as important differences in media reporting over time and across localities. Finally, the findings identify distinct response patterns in how Norwegian principals perceive, interpret and translate accountability demands, which range from alignment to accountability expectations to symbolic responses. By highlighting how performance-based accountability can drive behavioral change by reframing norms of good educational practice, and by changing how educators make sense of core aspects of their work, this dissertation challenges a central premise of educational accountability research; i.e. that external incentives and sanctions form the prime explanatory factors of behavioral change instigated by accountability reforms. Moreover, the dissertation contributes to the educational accountability literature by providing novel empirical findings on a lesser documented accountability regime in a Nordic educational setting, as well as by demonstrating the value of a multi-scalar approach to understand the deployment of accountability policies. The dissertation advocates that lowering the stakes forms an insufficient measure to prevent perverse effects from occurring, and calls for the need to re-think current dominant accountability approaches in education.

Pełny tekst źródłaOver the past twenty years the idea that gravity is holographic has become progressively concrete, materialised through the AdS/CFT correspondence, also known as the gauge/gravity duality. CFT stands for conformal field theory and in the correspondence it is a gauge-theory in the large N limit1. AdS stands for anti-de Sitter space-time, a maximally symmetric solution of Einstein’s equations with negative cosmological constant, it corresponds to the gravitational side of the duality. In some limits, theories on AdS with gravity in d + 1 dimensions can be mapped to CFTs without gravity in d dimensions and vice-versa, hence the name “duality”. Another term for the gauge/gravity duality is holographic duality. The term holography comes from the Greek words holos, “whole”, and graphe, “writing” or “drawing”. In physics, the term holography originates in optics, referring to the possibility of generating a 3-dimensional image as a projection from a bi- dimensional screen or film. In such a projection, despite of the fact that the film has one spatial dimension less than the projection, the film would contain all the information to recover the three-dimensional image. In the gauge/gravity duality, the gauge-theory behaves as a d-dimensional film which contains the same information as the (d + 1)-dimensional gravitational image. This analogy is reinforced by the fact that the duality relates the gravitational theory to the dual resulting quantum field theory (QFT) via boundary conditions of the fields living in the AdS bulk. In this sense, the gauge theory can be thought of as living at the boundary of AdS and the duality is also know as the bulk/boundary correspondence. One of the most important features of the correspondence is the mapping of a strongly coupled QFT into a weakly coupled gravitational theory and vice-versa. For this reason, in this thesis I will use a weakly coupled bulk theory to explore and identify non-perturbative features of QFT in the strong coupling regime. This thesis explores holography at zero and finite temperature. Our main concern are the CFTs in which scale invariance is either spontaneously or explicitly broken and the resulting QFT can be studied via the renormalisation group (RG). The profile of fields along the extra-dimension in the bulk is dual to renormalisation group flows in the QFT side (boundary), as the extra-dimension can be mapped to an energy scale. The mapping goes further by identifying bulk fields as dual to QFT running couplings, leading to the so-called holographic renormalisation group. With the holographic RG in what follows I will explore behaviours that are of an intrinsically non-perturbative nature from the QFT standpoint. The main results are as follows. At zero temperature, for a single coupling, we classified all possible solutions in our setup and identified three kinds of exotic flows corresponding to solutions reversing direction along the flow (bounces), flows skipping fixed points and solutions interpolating between minima of the potential. These results are generalised to many couplings at zero temperature. I also present a complete map between forms of the Hamilton's principal function and the gradient or non-gradient nature of the solutions. At finite temperature we considered a single coupling setup and explored the thermodynamics of the three kinds of above-mentioned exotic flows. We identified a phase transition between skipping and non-skipping solutions, a discontinuous free energy for a bouncing potential and the non-existence of a finite-temperature solutions for a chosen potential admitting a minimum-to-minimum solution

Pełny tekst źródłaThe “end of geography” is a disputed and controversial topic among economists and geographers.Nevertheless economists contribute to the recognition of the role of geography by highlighting thepersistently important influence of geographic distance over financial behaviour. In this way they takepart in the construction of the discipline. Seen in this light, the aim of this study is the integration ofEuropean UCITS as a relevant research topic in geography of finance. The study claims to questionthe functioning of the industry, its practices and its regulation. The focus on European markets ofUCITS enables to place the process of geographic expansion in the centre of analysis. If the principlesguiding this expansion find their origins in the US, this study highlights the active role of States,Europe and French actors. Differentiated circulation of capital within European markets reveals themulti-scalar logic of finance

Pełny tekst źródłaRecycling of nuclear fuel is based on liquid – liquid extraction. The dissolution of uranium dioxide in nitric medium is hence a key step at the head - end of the entire process. This particular dissolution is triphasic and autocatalytic, which means that numerous phenomena must be taken into account. A complete understanding of these phenomena, at macroscopic and microscopic scale, is necessary in order to model the solid disappearance rate in dissolvers. The kinetical parameters of the reaction were determined for both the catalyzed and non-catalyzed reactions. The kinetic study was realized thanks to a single particle approach. The reaction rates were measured by optical microscopy. This analytical technic enables to limit the catalyst accumulation at the solid - liquid interface. Moreover, nitrous oxides are products of the uranium dioxide dissolution. Evidence of a volumic reaction between these gases and the catalyst were found, and the kinetics of this reaction was estimated from the experimental results. Gas – liquid exchanges were shown to have an important impact on the catalyst concentration in the reactor. A model was realized thanks to the software Matlab to simulate these different phenomena. It was shown to be in good agreement with experimental results, at the microscopic and macroscopic scale. Dimensionless numbers were highlighted to describe the impact of each phenomenon on the solid disappearance, including the influence of the geometry and hydrodynamics of the reactor. Finally, ways of process optimization for autocatalytic reactions were determined thanks to the model. For instance, gas – liquid and solid – liquid exchanges were shown to be an interesting lever to fix the catalyst concentration in the reactor and at the solid surface

Pełny tekst źródłaThis study investigates changes in the organisation of the Bronze Age city of Hattuša (North Central Anatolia), during the time the site became the capital of the Hittites. Interweaving a diachronic, reproducible and multi-scalar analysis of the main living quarter of the city (the so-called Westterrasse), this study enables an innovative exploration of the organisation of the city-state (1950-1750 BCE) and capital of the Hittite kingdom (1700-1200 BCE), by attending to the links between politics and urban space. The chronological analysis demonstrates that the best-recovered phase of the Westterrasse dates to the 16th-15th century and not to the 14th-13th century as previously assumed. The study of the buildings, streets and sewage system indicate a high degree of planning for the Westterrasse with careful management of both public infrastructure and private dwelling, which underline the mediation necessary for their cohabitation. The insights afforded by examination of the distribution of finds reveal the broad contours of the population of the Westterrasse, as they are situated in the political context of the future Hittite capital

Pełny tekst źródłaTopological Data Analysis requires efficient algorithms to deal with the continuously increasing size and level of details of data sets. In this manuscript, we focus on three fundamental topological abstractions based on level sets: merge trees, contour trees and Reeb graphs. We propose three new efficient parallel algorithms for the computation of these abstractions on multi-core shared memory workstations. The first algorithm developed in the context of this thesis is based on multi-thread parallelism for the contour tree computation. A second algorithm revisits the reference sequential algorithm to compute this abstraction and is based on local propagations expressible as parallel tasks. This new algorithm is in practice twice faster in sequential than the reference algorithm designed in 2000 and offers one order of magnitude speedups in parallel. A last algorithm also relying on task-based local propagations is presented, computing a more generic abstraction: the Reeb graph. Contrary to concurrent approaches, these methods provide the augmented version of these structures, hence enabling the full extend of level-set based analysis. Algorithms presented in this manuscript result today in the fastest implementations available to compute these abstractions. This work has been integrated into the open-source platform: the Topology Toolkit (TTK)

Pełny tekst źródłaWe address the development of new numerical methods for the efficient resolution of stiff Partial Differential Equations modelling multi-scale time/space physical phenomena. We are more specifically interested in low Mach reacting flow processes, that cover various real-world applications such as flame dynamics at low gas velocity, buoyant jet flows or plasma/flow interactions. It is well-known that the numerical simulation of these problems is a highly difficult task, due to the large spectrum of spatial and time scales caused by the presence of nonlinear The adaptive spatial discretization is coupled to a new 3rd-order additive Runge-Kutta method for the incompressible Navier-Stokes equations, combining a 3rd-order, A-stable, stiffly accurate, 4-stage ESDIRK method for the algebraic linear part of these equations, and a 4th-order explicit Runge-Kutta scheme for the nonlinear convective part. This numerical strategy is implemented from scratch in the in-house numerical code mrpy. This software is written in Python, and relies on the PETSc library, written in C, for linear algebra operations. We assess the capabilities of this mechanisms taking place into dynamic fronts. In this general context, this work introduces dedicated numerical tools for the resolution of the incompressible Navier-Stokes equations, an important first step when designing an hydrodynamic solver for low Mach flows. We build a space adaptive numerical scheme to solve incompressible flows in a finite-volume context, that relies on multiresolution analysis with error control. To this end, we introduce a new collocated finite-volume method on adaptive rectangular grids, with an original treatment of the spurious pressure and velocity modes that does not alter the precision of the discretization technique. new hydrodynamic solver in terms of speed and efficiency, in the context of scalar transport on adaptive grids. Hence, this study presents a new high-order hydrodynamics solver for incompressible flows, with grid adaptation by multiresolution, that can be extended to the more general low-Mach flow configuration

Pełny tekst źródłaWith the support of the Barameter on China’s Development database, this dissertation covers 2254 county-level units, 338 prefecture-level units and 27 provincial units during the period of 1997 to 2010. Three major research issues have been reexamined at three different spatial scales using the geospatial analysis. Firstly, besides the temporal trend of economic inequality at multiple scales, the decomposable Theil index is applied to measure the intra/inter provincial/prefectural inequality as well as the urban-rural disparity. It is found that economic inequality is more prominent within provinces and between prefectures. Moreover, different from previous studies, the inequality within urban or rural areas is much more intense than the urban-rural disparity. Secondly, global and local spatial patterns of economic inequality are explored with the exploratory spatial data analysis technique. With the recent advances in geovisualization, a spatially explicit view of development mobility provides new insights on the role of spatial spillover effects. It is found that spatial clustering of economic development is investigated differently at these three spatial scales during the whole time period. Spatial integrated moves where the county-level unit’s development improves or worsens more than its neighbors are more frequently encountered than the reversed situation. Thirdly, spatial filtering method as well as multilevel modelling is employed to examine the causal mechanisms underlying economic inequality, which are nested among different spatial scales in China. The spatio-temporal and hierarchical analysis reveals that the county-level development is influenced significantly by its decentralization, fixed investment as well as urbanization rate. Simultaneously, the multi-mechanisms underlying regional development are spatially heterogeneous shaped largely by geography and policy.
The above findings thus contribute to the recent literature on economic inequality and suggest meaningful theoretical and policy implications. The county-level scale provides a novel perspective for understanding the trajectory of economic development in China. As suggested by the new economic geography literature, the prominent significance of space is reaffirmed at different spatial scales and reiterates pervasive existence of spillover effects operating at local scales. Furthermore, institutional reforms, such as empowering counties, should be enlarged to strengthen cooperative relationships among local governments thus realizing cross-border economic cooperation. Meanwhile, with the advances of geocomputing and geovisualization, new interdisciplinary approaches are needed to study this longstanding issue, so as to visualize the spatially integrated dynamics of regional development.
自从改革开放以来,中国经济保持着每年约10%的增长速度。在快速增长的同时,愈来愈显著的区域差异问题也成为困扰中央和地方政府的一大难题。许多学者已对区域差异问题展开了广泛且深入的研究,主要围绕区域差异的时间趋势、空间格局以及驱动因素等三大主要问题,但至今由于研究方法、研究尺度或者研究区域的不同,学者们很难达成对区域差异问题的统一见解,从而影响有效区域政策的制定。
区域差异研究发展到至今,大致经历了从宏观尺度向微观尺度的转变,研究的视角也开始更注重时间空间的动态结合,但仍存在以下不足:首先,以往研究主要围绕省级单元进行,或者仅以个别经济发展较快的省份作为研究对象,宏观尺度的研究掩盖了微观尺度上的区域发展过程,而个别省份的研究又影响了区域研究的整体性;其次,以往研究主要依赖于传统的统计方法,虽然一些最新的研究开始应用多层次模型等,但根据克鲁格曼提出的新经济地理,空间的作用不可忽略。空间模型的应用仍是以后更深入了解区域差异的重要方法。
本文针对现今区域差异研究的不足,在具有可比性时空动态分析的理论框架和多尺度多机制的分析框架下,从研究尺度和研究方法上进行创新,旨在为更深入理解区域差异问题提供一种新的视角。基于从1997年到2010年的全国县级发展数据库,本文首先探讨并比较县级、地级市及省级层面上区域差异的时间趋势,其次采用地理可视化技术和空间马尔科夫链,探讨了区域差异的空间格局及其动态特征,最后运用空间过滤方法及多层次多变量模型,探讨了不同尺度上驱动因素的相互作用。完成的主要研究工作如下:
首先,在分析了几种不同衡量区域差异的指标后,本文采用了泰尔系数衡量并比较全国省、市、县等不同尺度上的区域差异趋势,并利用泰尔系数的分解性特征,进一步研究区域差异在不同地理尺度上、城乡单元之间的关联性和特征,并着重研究了区域差异趋势的空间异质性。本文发现了区域差异在较小的空间尺度上更为显著,省级、地级市之间的区域差异大体呈现倒U型,但县域空间差异却呈现逐渐增强的趋势。通过多尺度泰尔系数的分解,区域经济差异在省内部和地级市之间更为明显。不同于以往的研究,城市或者乡村内部的差异远超过城乡差距,并成为导致县域差异的主因。另外,由于空间异质性,区域差异在东部、西部、中部、东北呈现不同的时间趋势及特征。
其次,在采用地理信息系统和探索性空间数据分析方法鉴定区域发展的全局和局部空间集聚特征后,为了进一步理解这种空间特征的动态性,本文采用空间马尔科夫链探讨区域发展的空间溢出特征,并结合地理可视化技术,更直观显示区域发展的空间关系及其变化。本文发现了区域发展主要呈现出空间集聚的特征,且空间集聚的强度在细尺度上更为明显。2004年开始,空间集聚开始呈现出逐渐北移的新特征。从时空角度看,一个区域的经济发展受它地理邻居单元的影响,呈现出共同进退的特征;一般而言,一个区域的发展速度均快过邻居的发展。
再次,采用空间过滤方法,并结合多层次模型,设计出符合理论框架的定量模型。并采用多尺度多变量模型分析财政分权、全球化、固定投资、人力资本以及政策对区域发展的影响,以及驱动因素在不同空间尺度间的相互影响。研究发现空间溢出对于县域发展作用不显著,但受到财政分权、外商投资以及固定资产的重要影响。地理和政策对于区域发展的影响呈现出空间异质性。
总之,本文从县级尺度出发,采用最新的一些地理空间方法重新探讨了区域差异的三大经典问题。本文证实了新经济地理学的观点,空间尺度和空间溢出对于重新理解区域发展问题至关重要。同时,本文提出了一些实用性较强的区域发展政策,旨在实现更为均衡的区域发展模式。

TOWARD ECO-CITY PLANNING AND GOVERNANCE:A MULTI-SCALAR EMPIRICAL COMPARATIVE STUDY Urban areas account for less than 2 percent of the surface of the Earth, but more than two-thirds of the greenhouse gas emissions and more than 70% of carbon dioxide emissions. Therefore, the city is the key to solving the problems of global warming and environmental change. Since 2005, the eco-city has gradually become a mainstream feature of the world's urban planning and development, and a considerable number of eco-cities around the world have been compared. However, a comparative analysis within an interpretive framework that reveals why some eco-cities are more successful than others is still lacking. This study puts forth a "research hypothesis" that the move toward an effective eco-cities proceeds from the concept of an ecological city, through planning and governance practices within a dynamic process of social actors’ interactive networks; and an "analytical framework" of governance network which integrates ‘itinerant governance logic’ and ‘participatory governance approach’. This comparative study explores the key factors of successful eco-city governance by comparing domestic and international cases with empirical investigation and by analyzing inductive inferences within cross-scales (from global to local) networks governance. These comparative cases of Stockholm city in Sweden and Taipei city, New Taipei city, Keelung city and Kaohsiung city in Taiwan reveal that the managerial governance model that best captures the effectiveness of governance but the populist governance model that worst captures the effectiveness of governance. Additionally, this study verifies the "research hypothesis" empirically and the "analytical framework" helps to elucidate the interactions among the governance logic, governance approach and governance effectiveness, as well as the characteristics and causes of "good governance" of an eco-city. Furthermore, the "analytical framework" provides a more comprehensive approach for actors self-learning to improve urban governance practices, because the "analytical framework" is an interactive network and an open system that help actors absorb, analyze and learn external resources. This "analytical framework" can be used to accelerate collective consensus of eco-city governance as a "learning framework" of social innovation, and act as a "planning framework" for the implementation of the strategy of eco-city governance. Moreover, it can be used as a "governance framework" to facilitate good governance in terms of other aspects. The results of the study are summarized as follows. An eco-city should be the basic cluster in which humans coexist with the environment leading by environmental civilization to transform material civilization in pursuit of economic activation, social harmony and environmental sustainability with local characteristics, urban ecosystem and healthy lifestyle. Toward eco-city governance is a complete process with desperate challenges from the concept to the practice of glocalization, which is embedded in a specific, dynamic and spatio-temporal environment by actors’ interactive process within a complex political, economic and social context. This dissertation contributes empirical research that confirms a research hypotheses and analytical framework for realizing in practices of eco-city governance. This study proposes a theoretical framework for the successful eco-city governance and argues that first, an integrated governance framework of itinerant logic and participatory approaches of governance must be constructed; secondly, the vertical and horizontal governance strategies across scales and networks must be developed; thirdly, governance strategies should strengthen the connections of governance plans (things) and governance networks (actors) with social practices; finally, it should build up a continuously review mechanism of dynamic adjustment and feedback concepts, framework and strategies of eco-city governance in order to enhance the effectiveness of governance as a fit model. Finally, the policy implications of the research findings include a total of 17 recommendations concerning the main issues that must be considered in eco-city planning and governance in Taiwan and in Taipei based on the national, metropolitan and city scales in Taiwan. The conclusions of this study indicate that the "planning" of an eco-city must focus on strengthening ties between planning and social practice, and the "governance" of an eco-city should take a holistic approach toward economic activation, social harmony and environmental sustainability with local characteristics within a healthy urban ecosystem and lifestyle.

The literature on the urban re-development of the neoliberalism has focused on the city-scales between the local government and the private sector. When the neo-liberalist urban strategies governance has practice the developmental state of East Asia, the capital which is the interface city is still strategically intervened by the state apparatus. Therefore many of the literature pay attention to the governance in the power of the central government, local government, and private sector. However, it is still ignore the impact of other scales governance which links from cross-border scales, regional scales, and citizens who are gradually emerging from the policy power stage. Therefore, this study is based on the multi-scale governance analysis structure of urban re-development. By combining the governance relationship between different scales, this study explain the problem of governance contradictory which is complex but more complete and real in the process of urban re-development policy. This study is a case study “New East District” in Taipei Nangang. Post-industrializing Nangang which had a large amount of Brownfield has become urban development strategy area of Taipei where is limited hinterland in the past 30 years. However, it's urban re-development policy has continued to delay and change. The main reason is the multi-scale governance contradiction under the neo-liberalist urban strategies. Therefore, this study analyzes the reasons for the delay and change of the urban re-development policy in Nangang. The results is that, first, cross-border/ state/ region scales governance contradiction makes the city-region competitiveness is limited. Under the influence of the structure, it reduced the private sector into the development of Nangang, and so far, “Taiwan Brain Power Base - Five Center Plan” without any private sector investment completed. Second, the public private partnership failure crisis of the policy implementation phase. The weak foundation of the public private partnership has led to speculations of public and private sectors. Thus, it affect the effectiveness of urban re-development policy. Third, the policy effect formed the "stagnation" of the public private partnership. The citizens was dissatisfied with the weak foundation of the public private partnership and the polarization development of the neoliberalism, thus formed political pressure to force Taipei city government to adjust the policy. However, after the end of 2014, the mayor's team of KE,WEN-ZHE took too drastic policy adjustments, resulting in the public sector trust and social capital is depreciating, making the private sector do not want to partner with public sector , and then form a new wave of policy delays and changes.

Pełny tekst źródłaExcavations in the 1920s and 1970s at the Sculptor’s Cave, North-East Scotland, revealed that the site was used for mortuary rituals during the Late Bronze Age (c. 1100–800 BC) and Roman Iron Age (late first to fourth centuries AD), whilst a series of Pictish symbols carved into its entrance walls suggest that the cave’s importance continued into the Early Medieval Period. A new programme of analysis has utilised advanced 3D digital documentation and 3D metrology (specifically, 3D laser scanning) to enable this inaccessible site to be appreciated by wider audiences and analysed remotely. Detailed in situ recording of the Pictish symbols was undertaken using macro-level structured light scanning and the high-fidelity digital models blended with terrestrial laser scan data of the cave interior to show the location and detail of the carvings. This chapter examines the value of emerging digital approaches in the analysis, presentation and management of the Sculptor’s Cave, from the elucidation of additional carved details and the monitoring of surface degradation, to the dissemination of this difficult-to-access site to the wider public via online platforms.

The recent trend in optical fiber communication is moving toward developing the multi-core fiber (MCF) with each fiber core supporting either a single mode or multi modes. It will effectively increase the bandwidth of the communications system. However, for the single-mode MCF as we reduce the cladding spacing between each core the coupling among each core increases. This will result in undesirable signal crosstalk coming from adjacent fiber cores. It is interesting to note that present theoretical prediction of the coupling strength of a single-mode MCF is a few orders of magnitude larger than experimentally measured values. We can only speculate that the coupling strength is reduced partly due to random fluctuation of relative phases among neighboring cores and partly due to polarization variation among fiber bores. Since the cross sectional area of a MCF is of several hundred/thousand wavelength square, it is impossible to conduct mode field analysis of these MCFs using commercial software using traditional mode-solving techniques such as the finite-element method or beam propagation method. In this paper, considering the small index contrast in the MCF we propose to develop a rigorous scalar coupled-mode theory (CMT) to analyze mode fields of a given single-mode MCF. The global MCF mode fields are then represented by some linear combination of linear polarized fiber mode field attributed to each single individual fiber core. In the end we have implemented Matlab codes for the MCF under CMT formulation. This program not only computes every eigen-mode of the global MCF waveguide structure it also allows us to study the mode field evolution of the single-mode MCF. As we initially turn on one of the fiber core we are able to observe that the energy gradually spread across all fiber cores according to the governing equation. When combined with new broadband MCF optical amplifiers we may see another ten-fold increase in the capacity of the optical fiber communication system with a minimum increase in cost.

Pełny tekst źródłaShamanic belief systems represent the first form of religious practice visible within the global archaeological record. Here we report on the earliest known evidence of shamanic costume: modified red deer crania headdresses from the Early Holocene site of Star Carr (c. 11 kya). More than 90% of the examples from prehistoric Europe come from this one site, establishing it as a place of outstanding shamanistic/cosmological significance. Our work, involving a programme of experimental replication, analysis of macroscopic traces, organic residue analysis and 3D image acquisition, metrology and visualisation, represents the first attempt to understand the manufacturing processes used to create these artefacts. The results produced were unexpected—rather than being carefully crafted objects, elements of their production can only be described as expedient.
