description: Der Fokus dieser Arbeit lag auf der Entwicklung eines kompetitiven Verfahrens zur Abtrennung biologischer Wertstoffe aus Naturstoffquellen mittels tensid-basierter Extraktion. Die Stabilität des Prozesses wurde in diskontinuierlichem als auch im kontinuierlichem Betrieb gezeigt. Demzufolge war es möglich, die tensid-basierte Extraktion von sensitiven Biomolekülen im Technikum- und Pilotmaßstab durchzuführen. Auf diese Weise konnte das Potential des Prozesses als neue Trennoperation zur Gewinnung verschiedener Wertkomponenten in der Biotechnologie aufgezeigt werden.
description: This work focused on the development of a surfactant-based extraction process as a competitive process for the recovery of biomaterials from authentic feedstocks. The stability of the extraction was demonstrating in a batch and a continuous mode. Therefore, it was possible to apply the technique for the separation of sensitive biomaterials in technical and pilot scale. Hence, attention was given to the potential of the process as a new separation tool for sensitive, valuable compounds in the biotechnology.

description: This paper presents a method of optimization, based on both Bayesian Analysis technical and Galois Lattice of Fuzzy Semantic Network. The technical System we use learns by interpreting an unknown word using the links created between this new word and known words. The main link is provided by the context of the query. When novice's query is confused with an unknown verb (goal) applied to a known noun denoting either an object in the ideal user's Network or an object in the user's Network, the system infer that this new verb corresponds to one of the known goal. With the learning of new words in natural language as the interpretation, which was produced in agreement with the user, the system improves its representation scheme at each experiment with a new user and, in addition, takes advantage of previous discussions with users. The semantic Net of user objects thus obtained by learning is not always optimal because some relationships between couple of user objects can be generalized and others suppressed according to values of forces that characterize them. Indeed, to simplify the obtained Net, we propose to proceed to an Inductive Bayesian Analysis, on the Net obtained from Galois lattice. The objective of this analysis can be seen as an operation of filtering of the obtained descriptive graph.

description: In the last few decades, several blood derived products such as platelet-rich plasma (PRP), plasma rich in growth factors (PRGF) and autologous serum (AS) have been used for the treatment of ocular surface disorders. Recently, insulin has been proposed to be used as an alternative for the treatment of ocular surface diseases. The aim of this study was to evaluate the biological potential of PRGF eye drops in comparison with AS and insulin on ocular surface cells. Blood from three healthy young donors was collected to obtain autologous serum (AS) eye drops and plasma rich in growth factors (PRGF) eye drops. Insulin (Actrapid®) was diluted at 1 and 0.2 IU/mL. The biological potential of PRGF, AS and insulin was assessed by proliferation in HCE, HK and HConF cells. Wound healing assay was performed in HCE cells after incubation with the different treatments. HConF and HK cells were differentiated to myofibroblast after treatment with 2.5 ng/mL of TGF-β1 and then incubated with all treatments. PRGF eye drops induced significantly higher proliferation rate compared to AS or insulin in HConF and HK cells, but not in HCE cells. In addition, the percentage of wound healing area was significantly reduced after PRGF treatment in comparison with AS or insulin treatment. Furthermore, PRGF significantly reduced the number of myodifferentiated cells compared to AS and insulin at both concentrations analyzed. The results obtained in the present study show that PRGF increases the biological activity of the ocular surface cells and reduces the expression of fibrosis marker compared to insulin or AS. The present study suggests that plasma rich in growth factors eye drops are a more effective therapy than insulin and autologous serum eye drops for the treatment of ocular surface diseases.

description: We present a time, spectral and imaging analysis of the X-ray reflector in NGC 4945, which reveals its geometrical and physical structure with unprecedented detail. NGC 4945 hosts one of the brightest AGN in the sky above 10 keV, but it is only visible through its reflected/scattered emission below 10 keV, due to absorption by a column density of ~4\times10^24 cm-2. A new Suzaku campaign of 5 observations spanning ~6 months, together with past XMM-Newton and Chandra observations, show a remarkable constancy (within <10%) of the reflected component. Instead, Swift-BAT reveals strong intrinsic variability on time scales longer than one year. Modeling the circumnuclear gas as a thin cylinder with the axis on the plane of the sky, we show that the reflector is at a distance >30-50 pc, well within the imaging capabilities of Chandra at the distance of NGC 4945 (1"~18 pc). Accordingly, the Chandra imaging reveals a resolved, flattened, ~150 pc-long clumpy structure, whose spectrum is fully due to cold reflection of the primary AGN emission. The clumpiness may explain the small covering factor derived from the spectral and variability properties.

description: The historical space is an important idea to blur boundaries between time and space. As showed in the case of Pan River, I have demonstrated value and signification of heritage site could be sensed through the spatial narrative written by the ancient. It was like a star in the sky holding the potential to lighten the way of the present to the future. Ancient site in Qufu’s local gazetteer was recorded as ancient traces, where “the righteous men went to the site, viewing traces and behaviors towards imagining the ancient.” China holds heritage sites of a great number for sure, but the value of using them is to step on the traces of the ancient and think with a dialogical heart, only in this way could we still feel the unchangeable power in historical space and be touched. Moreover, it is how no matter how ruined or vacant this site will be, it could still be sensed as a respective place as moral space.

description: Biometric authentication systems that make use of signature verification methods often render optimum performance only under limited and restricted conditions. Such methods utilize several training samples so as to achieve high accuracy. Moreover, several constraints are imposed on the end-user so that the system may work optimally, and as expected. For example, the user is made to sign within a small box, in order to limit their signature to a predefined set of dimensions, thus eliminating scaling. Moreover, the angular rotation with respect to the referenced signature that will be inadvertently introduced as human error, hampers performance of biometric signature verification systems. To eliminate this, traditionally, a user is asked to sign exactly on top of a reference line. In this paper, we propose a robust system that optimizes the signature obtained from the user for a large range of variation in Rotation-Scaling-Translation (RST) and resolves these error parameters in the user signature according to the reference signature stored in the database.

description: We propose a realistic experiment to demonstrate a dynamic Kosterlitz-Thouless transition in ultra-cold atomic gases in two dimensions. With a numerical implementation of the Truncated Wigner Approximation we simulate the time evolution of several correlation functions, which can be measured via matter wave interference. We demonstrate that the relaxational dynamics is well-described by a real-time renormalization group approach, and argue that these experiments can guide the development of a theoretical framework for the understanding of critical dynamics.

description: Sockeye salmon are deemed essential to life by Secwépemc Indigenous communities living near the Adams River in South Central British Columbia (BC). They are also an ecological keystone species and a significant contributor to the BC economy. However, salmon populations are in decline throughout the Pacific Northwest, putting communities, economies and ecosystems at risk. Using Actor-Network Theory (ANT) as a lens, we identify the network of actors connected to the Adams River salmon run, examine actor relationships, and consider the impacts these relations have on sustainable conservation practices. We use a community-based participatory research methodology and interviews to investigate the complexity of stakeholder relationships to wild Pacific salmon in BC. Based on our results, there is strong evidence to suggest that localized approaches to salmon conservation, ones guided by local experience and knowledge, are critical to developing inclusive and effective policies.

description: By actively promoting museum digitalization, Japan finds an idiosyncratic way to museum digitalization. The mode of collaboration, in which the government plays a leading role while large enterprises’ R&D capabilities and museum’s cultural dynamics are both allowed to give full play, turns these powerful enterprises into the solid backing of museum digitalization, provides a concrete solution to the common financial and technical challenges museums face in the process. In the course of such collaboration, large enterprises succeed in cultivating a number of talents who understand both business world and museum operation. Thanks to their experiences in the business world, compared with museum professionals, they play a more vital role in marketing the potential commercial exploitation of related digital technologies. The benefits large enterprises could possibly gain from such mode of collaboration - realizing social values, enhancing corporate image, for instance - help to motivate their active involvement, thereby forming a positive cycle of sustainable development.

description: The AGN-host co-evolution issue is investigated here by focusing on the evolution of the [\ion{O}{3}]$\lambda5007$ emission-line profile. In order to simultaneously measure both [\ion{O}{3}] line profile and circumnuclear stellar population in individual spectrum, a large sample of narrow emission-line galaxies is selected from the MPA/JHU SDSS DR7 catalog. By requiring that 1) the [\ion{O}{3}] line signal-to-noise ratio is larger than 30, 2) the [\ion{O}{3}] line width is larger than the instrumental resolution by a factor of 2, our sample finally contains 2,333 Seyfert galaxies/LINERs (AGNs), 793 transition galaxies, and 190 starforming galaxies. In additional to the commonly used profile parameters (i.e., line centroid, relative velocity shift and velocity dispersion), two dimensionless shape parameters, skewness and kurtosis, are used to quantify the line shape deviation from a pure Gaussian function. We show that the transition galaxies are systematically associated with narrower line widths and weaker [\ion{O}{3}] broad wings than the AGNs, which implies that the kinematics of the emission-line gas is different in the two kinds of objects. By combining the measured host properties and line shape parameters, we find that the AGNs with stronger blue asymmetries tend to be associated with younger stellar populations. However, the similar trend is not identified in the transition galaxies. The failure is likely resulted from a selection effect in which the transition galaxies are systematically associated with younger stellar populations than the AGNs. The evolutionary significance revealed here suggests that both NLR kinematics and outflow feedback in AGNs co-evolve with their host galaxies.

description: В статье представлены результаты исследований по изучению влияния агротехнических приѐмов возделывания бобово-злаковых агрофитоценозов на ботанический состав и продуктивность при длительном трѐхукосном использовании. Метод исследований включал проведение полевого опыта на осушенной, средне окультуренной, дерново-подзолистой, среднесуглинистой почве. Агрофитоценозы состояли из одноукосного клевера, двуукосного клевера, люцерны изменчивой, овсяницы луговой, овсяницы тростниковой, тимофеевки, костреца, райграса многолетнего. Для подкормки травосмесей в начале вегетации использовали диаммофоску, после первого укоса аммиачную селитру. Целью исследований являлось установление влияния агротехнических приѐмов возделывания бобово-злаковых агрофитоценозов на изменение ботанического состава и продуктивность в условиях Европейского Севера РФ. Научная новизна проведѐнных исследований заключается в том, что впервые на осушенных дерново- подзолистых почвах изучено влияние агротехнических приѐмов на изменение ботанического состава и урожайности бобово-злаковых агрофитоценозов при трѐхукосном использовании. В результате исследований установлено, что состав травостоев изменялся по годам пользования, что в свою очередь повлияло на урожайность трав и питательность полученного растительного сырья. Во все годы пользования сеянные виды трав преобладали в составе агрофитоценозов со снижением к 4-у году пользования до 65,6-86,6%. Содержание бобовых трав было высоким только в 1-й год пользования, затем в урожае преобладали злаковые виды. Со второго года пользования овсяница тростниковая в вар 3,5,8,9 заметно увеличила в урожае своѐ долевое участие. Урожайность зависела от видового 2 состава агрофитоценозов. В 1-й год пользования, когда преобладали бобовые виды, получен самый высокий урожай 50-57 т/га зелѐной массы. За четыре года пользования урожайность на уровне контроля обеспечили травосмеси с овсяницей тростниковой (вар. 3,5,8-9), достоверно на 0,7-1,7 т/га СВ уступали контролю агрофитоценозы с кострецом, райграсом и овсяницей луговой. Травосмеси при 3-х укосном использовании превосходили двухукосное по сбору протеина на 11-31%, по содержанию протеина в растительной массе на 23,5-43,1%. Область применения – сельхозпредприятия Европейского Севера РФ.

description: Although the Hardy inequality corresponding to one quadratic singularity, with optimal constant, does not admit any extremal function, it is well known that such a potential can be improved, in the sense that a positive term can be added to the quadratic singularity without violating the inequality, and even a whole asymptotic expansion can be build, with optimal constants for each term. This phenomenon has not been much studied for other inequalities. Our purpose is to prove that it also holds for the gaussian Poincaré inequality. The method is based on a recursion formula, which allows to identify the optimal constants in the asymptotic expansion, order by order. We also apply the same strategy to a family of Hardy-Poincaré inequalities which interpolate between Hardy and gaussian Poincaré inequalities.

description: We report results from our deep Chandra X-ray observations of a nearby radio galaxy, 4C+29.30 (z=0.0647). The Chandra image resolves structures on sub-arcsec to arcsec scales, revealing complex X-ray morphology and detecting the main radio features: the nucleus, a jet, hotspots, and lobes. The nucleus is absorbed (N(H)=3.95 (+0.27/-0.33)x10^23 atoms/cm^2) with an unabsorbed luminosity of L(2-10 keV) ~ (5.08 +/-0.52) 10^43 erg/s characteristic of Type 2 AGN. Regions of soft (<2 keV) X-ray emission that trace the hot interstellar medium (ISM) are correlated with radio structures along the main radio axis indicating a strong relation between the two. The X-ray emission beyond the radio source correlates with the morphology of optical line-emitting regions. We measured the ISM temperature in several regions across the galaxy to be kT ~ 0.5 with slightly higher temperatures (of a few keV) in the center and in the vicinity of the radio hotspots. Assuming these regions were heated by weak shocks driven by the expanding radio source, we estimated the corresponding Mach number of 1.6 in the southern regions. The thermal pressure of the X-ray emitting gas in the outermost regions suggest the hot ISM is slightly under-pressured with respect to the cold optical-line emitting gas and radio-emitting plasma, which both seem to be in a rough pressure equilibrium. We conclude that 4C+29.30 displays a complex view of interactions between the jet-driven radio outflow and host galaxy environment, signaling feedback processes closely associated with the central active nucleus.

description: This paper, by referring to the archaeological reports and local gazetteers and comparing images of porcelain wares, makes a comprehensive and in-depth analysis of the layout of power and space in Jingdezhen Imperial Factory according to its geography, geomancy, security management, space regulation, architectural features, production characteristics and production layout. It contends that the Imperial Factory which integrates porcelain making factory with local government is the embodiment of absolute monarchy in ceramic culture. The factory is located on Zhushan mountain, the center of Jingdezhen’s industry, business and transportation. Being at the center, it gives off an air of prestige and majesty, overlooking dominantly the surrounding private kilns. It has also turned the political system into power operation, setting up not only workshops but also administrative offices. By taking advantage of the best resources, it has produced porcelain for imperial family and court. Its specialized production has solved the contradiction between complicated technology and numerous procedures of production. The shape, color and pattern of the porcelain wares are strictly stipulated and the best of the best wares are demanded. Hence the porcelain production is featured with longest firing, largest scale, superb craftsmanship, and best kinds of wares. All of these reveal the process and rule power and space are intersected and different cultures overlapped.

description: We propose a potentially practical scheme to simulate artificial Abelian gauge field for polaritons using a hybrid quantum system consisting of nitrogen-vacancy center ensembles (NVEs) and superconducting transmission line resonators (TLR). In our case, the collective excitations of NVEs play the role of bosonic particles, and our multiport device tends to circulate polaritons in a behavior like a charged particle in an external magnetic field. We discuss the possibility of identifying signatures of the Hofstadter "butterfly" in the optical spectra of the resonators, and analyze the ground state crossover for different gauge fields. Our work opens new perspectives in quantum simulation of condensed matter and many-body physics using hybrid spin-ensemble circuit quantum electrodynamics system. The experimental feasibility and challenge are justified using currently available technology.

description: This paper examines alternatives to top-down approaches to heritage management and development. One of the key issues facing communities around the globe today is the Authorized Heritage Discourse (AHD)--the determination of heritage values by “experts” and government officials on behalf of the people. It is all too common to find local people alienated by such practices and searching for ways in which they can take ownership of their own heritage. Community-based research that shares power and is participatory is one avenue that is quickly developing in many regions around the globe.
In Africa, a number of villages and other small communities have taken the initiative to preserve and develop their heritage, free of outside control. Important lessons may be drawn from these experiences, particularly the use of discourse-based research that captures how the people define and live out their heritages through everyday practice.

description: Recognizing that community-based natural resource management (CBNRM) approaches have had mixed success in pastoral rangelands, this paper compares five case studies—two from Kenya, two from Ethiopia and one from Tunisia—to identify aspects of social-ecological context that affect the implementation and success of CBNRM in pastoral settings. Data for each case was collected following a common protocol. Among the characteristics that emerged from our study as important were socio-political and biophysical characteristics of the wider landscape within which the community’s rangeland territory is located and the extent to which that territory is circumscribed by some combination of other land uses and land tenure types, major political boundaries, and physical landscape features. The analysis of these cases suggests that where pastoralist communities coexist in large, open rangeland landscapes, rather than a narrowly community-based approach, natural resource management interventions need to be explicitly multi-level and horizontally flexible.

Memory work

description: Grassroots and radical archives have increasingly been presented as more socially just alternatives to dominant institutions. This increased recognition is weighted with a set of risks that minoritized memory-workers must navigate. Under the auspices of the gendered, racial-capitalist settler state, dominant institutions will ultimately work to diffuse the potentials of radical memory work and organizing that threatens their hegemony while continuing to profit from this work. In this thesis, I ask, what are we to do—as trans, queers, crips, criminals, whores, dykes, fags and anarchists—who hope to do liberatory memory work while existing in spaces that at best are extracting from us, and at worst, killing us? Can memory work existing under the auspices of the white supremacist settler-state, within these institutions, be truly revolutionary? How can we document our social movement histories, working class resistance, and lawless subversion without replicating the administrative violence, surveillance, and carceral logics of the nation-state? To address these questions, I draw upon my experiential knowledge organizing with the books to prisons collective, Inside Books Project (IBP) over a span of nine years. As a queer-crip, non-binary anarchist and prison abolitionist, my political praxes formed the basis of an archival methodology that enabled me to navigate some of these questions in my capacity as the project archivist for IBP. I argue that frameworks of Black feminist anarchism and critical trans politics can inform an archival praxis that emerges in the interstices of impossible being and becoming embodied by the enslaved, incarcerated, detained, maimed, undocumented, disabled, and disposable. Drawing on the work of Black archivists and anarchists, I will discuss how I have applied these praxes in my work documenting the narratives of incarcerated people in Texas. In doing this, I hope to promote a more sustained engagement with Black feminist anarchism and a critical trans politics in the field of memory work and archives. I also hope to encourage anarchists and others organizing towards collective liberation to more actively engage in memory work as a praxis of disruption, subversion, and radical futurity

description: This study was performed in order to select a proper fibre for the application of a distributed temperature sensing system within a hot geothermal well in Iceland. Commercially available high temperature graded index fibres have been tested under in-situ temperature conditions. Experiments have been performed with four different polyimide coated fibres, a fibre with an aluminum coating and a fibre with a gold coating. To select a fibre, the relationship between attenuation, temperature, and time has been analyzed together with SEM micrographs. On the basis of these experiments, polyimide fibres have been chosen for utilisation. Further tests in ambient and inert atmosphere have been conducted with two polyimide coated fibres to set an operating temperature limit for these fibres. SEM micrographs, together with coating colour changes have been used to characterize the high temperature performance of the fibres. A novel cable design has been developed, a deployment strategy has been worked out and a suitable well for deployment has been selected.

description: We present an observational study towards the young high-mass star forming region G23.44-0.18 using the Submillimeter Array. Two massive, radio-quiet dusty cores MM1 and MM2 are observed in 1.3 mm continuum emission and dense molecular gas tracers including thermal CH$_3$OH, CH$_3$CN, HNCO, SO, and OCS lines. The $^{12}$CO (2--1) line reveals a strong bipolar outflow originated from MM2. The outflow consists of a low-velocity component with wide-angle quasi-parabolic shape and a more compact and collimated high-velocity component. The overall geometry resembles the outflow system observed in the low-mass protostar which has a jet-driven fast flow and entrained gas shell. The outflow has a dynamical age of $6\times10^3$ years and a mass ejection rate $\sim10^{-3} M_{\odot}$ year$^{-1}$. A prominent shock emission in the outflow is observed in SO and OCS, and also detected in CH$_3$OH and HNCO. We investigated the chemistry of MM1, MM2 and the shocked region. The dense core MM2 have molecular abundances of 3 to 4 times higher than those in MM1. The abundance excess, we suggest, can be a net effect of the stellar evolution and embedded shocks in MM2 that calls for further inspection.

description: We analyse restrictions on the stochastic superspace parameter space arising from 1 fb$^{-1}$ of LHC data, and bounds on sparticle masses, cold dark matter relic density and the branching ratio of the process $B_s \rightarrow μ^+ μ^-$. A region of parameter space consistent with these limits is found where the stochasticity parameter, ξ, takes values in the range -2200 GeV < ξ< -900 GeV, provided the cutoff scale is $\mathcal{O}(10^{18})$ GeV.

description: The National Museum of Ethnology (Minpaku) was founded in 1974 as an Inter-University Research Institute housing a museum and graduate school. A museum is more than a place to store intangible and tangible heritage. Along with its responsibility for conserving and passing on cultural materials, it also creates new culture. On March 11, 2011, Japan was struck by an earthquake and tsunami of unprecedented proportions. From one month after the disaster, conservation experts from Minpaku participated in the rescue of tangible cultural resources for the period of eight months. At the same time, our disaster response team worked with village residents in damaged localities, assisting their efforts to replace costumes and ornaments for traditional performing arts that had been washed out to sea, or to repair damaged lion heads, to aid in reviving traditional performing arts. We had thought that, in the process of revival and recovery, the re-launch of festivals and traditional performing arts would come later than the construction of the homes and livelihoods of the local people. In one case, Minpaku, based on its research, was able to provide deer antlers for the headdresses needed to revive the deer dance, an intangible cultural heritage of a village in Iwate Prefecture. Village elders worked the antlers we donated, restored the costumes, and within a year were able to produce ten full sets of costumes. Subsequently, the deer dance was performed in village after village to calm the spirits of the dead, ward off evil spirits, and restore the confidence of people afflicted by the disaster. In this way, a traditional performing art contributed to the revival and rebuilding of the affected communities. In another village the repair and restoration of stone lions’ heads and providing aid for refugees from the disaster were further other examples of organized activity carried out in connection with the traditional performing arts. In sum, our experience in the wake of the Great East Japan Earthquake demonstrates that a museum’s efforts to revive and restore traditional performing arts can do more than sustain folk arts. It can also play a vital role in rebuilding the spirits of communities and localities affected by disasters.

description: Huazhao Festival is a traditional one that is celebrated in early spring and appeals to both highbrows and lowbrows. Once, it was as significant as Lantern Festival and Mid-autumn Festival. Ever since Tang Dynasty, it has undergone stages of emerging, thriving, declining and restoring. Originally, people only had a spring outing enjoying beautiful flowers at this festival; later, various other folk activities were also carried out on this day, including catching butterflies, picking wild vegetables, offering sacrifices to gods, predicting bumper and poor harvest, fastening strips of red cloth to stems of flowers and trees (shang hong), having competitions on grass, encouraging agriculture, holding and attending banquets, writing articles, paying court and so on. These activities demonstrated such characteristics of the national culture of China as elegance, harmony and life-friendliness. Obviously different from other traditional festivals like Spring Festival, Mid-autumn Festival, Dragon Boat Festival, etc, Huazhao Festival has unique style and value. Despite its fading away from people’s life due to changes in modern society, its cultural glamour and comprehensive value still exist. Along with economic and social development and the increase of people’s spiritual and cultural demands, Huazhao Festival has regained people’s attention. It has been restored and hosted in some regions and identified as an intangible cultural heritage. By means of literature review, the folk customs of Huazhao Festival was re-presented to some extent in this paper. Its modern values in areas including health, culture, ecology and industry were analyzed. This paper is of certain significance, in respect of conserving and inheriting this national festival, promoting its restoration in more regions in a way more approximate to historical tradition and giving play to its unique role to benefit modern society.

description: It has been recently proposed that gravity might be an entropic force. Although a well defined fundamental description for such a mechanism is still lacking, it is still possible to address the viability of phenomenological models of entropic-inspired modified gravities. I will summarize some recent work directed to using cosmology as a tool to constraint scenarios in which the modifications are aimed to explain the physics behind dark energy and inflation. A phenomenological modification is able to explain cosmic acceleration at the background level and fit observations, but simple inflation models with higher curvature corrections are in conflict with late time matter domination.

description: Gu Pan Pool neighborhood got its name because of Gu Pan Chi, (古泮池，the ancient Pan Pool), located in the southeastern part of Confucius’ birthplace, Qufu, the birth place of Confucius with a history of 3000 year. Gu Pan Pool has been recently under preservation with the joint efforts of World Bank cultural heritage conservation project and the local municipal government. With disparate interests in mind, the three stakeholders of heritage, the world bank, Qufu municipal government and local residents are contradictory with each other in the regeneration process, in which the local voices are often ignored. The purpose of this paper is to rethink heritage making from a historical and indigenous perspective in the contemporary Chinese urban historic landscape planning process. The author contends that the cultural value and pluralism embedded in the ritual way of thinking in Chinese Classics inherited and transmitted for thousands of years could be an alternative way of thinking for the landscape planning practices in the homogenizing culture of global capitalism. This research aims to reinterpret and re-activate Confucianism as cultural heritage to enrich the understanding and hence the sustainability related to human action in urban spaces with emphasis on planning processes in contemporary China.
