The Hannes Meyer Seminars at the Bauhaus Dessau (1980–1986) as a Contact Zone for Finnish and East German Architects
Creators: name: Lange, Torsten
Publisher: name: FOOTPRINT
Year: 2020

description: This article charts transnational exchanges between East German and Finnish architects in the development of adaptive housing solutions for urban sites. It focuses on the Hannes Meyer Seminars – a series of annual international design workshops held at the Bauhaus Dessau from 1980 to 1986 – as a contact zone. The seminars challenged dominant forms of mass housing, and put forth alternative models to suit historic contexts. These exchanges went beyond previous (one-directional) material and technical exports that stretched back as far as the mid-1950s. As a result of the policy of détente in the early 1970s, relations between Finland and the GDR began to form an ever more complex and entangled network, with greater emphasis on knowledge transfer and collaboration. Formal agreements on ‘scientific and technical cooperation’ thus provided the framework for the intensification of contacts between design schools such as the College for Architecture and Civil Engineering (HAB, Hochschule für Architektur und Bauwesen) in Weimar and the Technical University Tampere. This opened a dialogue about contextual design (the adaptation of industrialised housing to the different needs and lifestyles of individual users), as well as historic settings, new tools such as CAD/CAM, sociological and historical research, and the discourse of postmodernism.

description: The replacement of existing classical weirs with labyrinth weirs is a proven techno-economical solution and a means to increase the discharge capacity when rehabilitating existing structures. However, flows exiting a labyrinth weir are complex, three-dimensional, and aerated; additional information is needed regarding energy dissipated by such weirs. In this study, three labyrinth weirs with different crest lengths were simulated with FLOW-3D HYDRO. Reynolds-averaged Navier-Stokes (RANS) modeling with the use of finite-volume method and Re-Normalisation Group (RNG) k-ε turbulence closure were employed. An attempt was made to more precisely account for the flow field in the downstream region. Consequently, the velocity head was determined with both depth-averaged and section-averaged velocities. Additionally, the kinetic energy correction coefficient was considered. A comparison of the computational fluid dynamics (CFD) results with prior experimental data showed that the residual energy was influenced by factors such as probe position and geometric parameters. A minor influence was observed for the kinetic energy correction coefficient. Overall, the high amount of energy dissipation was underlined and an acceptable agreement between simulated and literature data was documented.
Histoire Croisée

description: Globalization makes understanding worldmaking processes a crucial issue. During the Cold War the social sciences mainly addressed this issue through comparative studies which mirrored the logic of the world-historical confrontation. In this respect 1989 fostered not only a political turn but an epistemological one. The new political situation fueled the development of approaches dedicated to the study of relations and interdependencies between different parts of the world. Like entangled, shared or connected histories, Histoire croisée takes a cross-border approach.Their common feature is shifting the analysis from comparative approaches centered on territorial entities to the relationships that flow through and the interactions which constitute them, as well as moving away from approaches solely focused on state relationships. Dedicated to the study of intersecting processes in various settings, Histoire croisée is driven by an empirical, methodological and epistemological shift that involves redefining the object of research.

description: The coalescences of stellar-mass black-hole binaries through their inspiral, merger, and ringdown are among the most promising sources for ground-based gravitational-wave (GW) detectors. If a GW signal is observed with sufficient signal-to-noise ratio, the masses and spins of the black holes can be estimated from just the inspiral part of the signal. Using these estimates of the initial parameters of the binary, the mass and spin of the final black hole can be uniquely predicted making use of general-relativistic numerical simulations. In addition, the mass and spin of the final black hole can be independently estimated from the merger--ringdown part of the signal. If the binary black hole dynamics is correctly described by general relativity (GR), these independent estimates have to be consistent with each other. We present a Bayesian implementation of such a test of general relativity, which allows us to combine the constraints from multiple observations. Using kludge modified GR waveforms, we demonstrate that this test can detect sufficiently large deviations from GR, and outline the expected constraints from upcoming GW observations using the second-generation of ground-based GW detectors.

Year: 2023

description: A Piano key weir (PK weir) is a non-rectilinear spillway commonly used to augment the discharge capacity at the dams and diversion structures. Installation of such hydraulic structures may alter the flow characteristics, sediments transport and sedimentation in the river channels. The present study deals with an experimental investigation of three dimensional velocities near the two different laboratory models of PK weir having noses with an outlet overhangs. The purpose of this study is to observe the flow field in the vicinity of a one-cycle and two-cycle PK weir to understand the flow behavior of the weir that may be useful for sediment movement over weir. The velocity profile was measured at various grid points for both models considering unit discharges of 48.5×10-3 m2/s and 49×10-3 m2/s. The velocity fields near both inlet and outlet keys were examined and it was found that there is a considerable increase in the vertical (y-component) and lateral (z-component) velocities. It was observed that the rise in the mean velocity along longitudinal, vertical and lateral direction was more for two cycle PK weir due to increased crest length. For both discharge, the maximum velocity was observed near the inlet key. Computational Fluid Dynamics (CFD) simulations were also used to understand the flow configuration over the PK weir. It was seen that the magnitude of velocity increased due to vertical contraction near the weir and the flow velocity is very high immediately downstream of PK weir.

description: Various forms of violence and conflict continue to shape our habitats. What historically has been straightforward and even obvious two-way dependency, in recent years took more subtle and covert form due to sophisticated technological advancements in the fields of media, surveillance and armament. Recognising the detrimental effects of these new developments on the way we experience, conceptualise and build our environments, Footprint #27 proposes artistic reflections, cross-media inquiry and counter-tactics as new powerful tools to rethink the complex relationship between conflict, space and mediation. On one hand, the aim of this issue is to deepen and expand theoretical considerations that substantiate investigations of spatial conflicts by making them truly interdisciplinary. On the other, it seeks to empower architects and artists in their pursuit of exposing, critiquing and fighting spatial violence by reclaiming/unlocking the enormous potential of media tools.

description: With rising demand for storing water in reservoirs, many spillways require modification by optimizing their shape for enhancing their discharge capacity. A Piano Key Weir (PK weir) is a modified weir and it is installed at the dams to augment the discharge capacity of the weir. Due to different geometrical configurations of PK weirs, the hydraulic performance of the weir is still in evolving research. In this study, hydraulic performance of two different models of PK weir is studied experimentally. All the configurations of both the PK weir are same except the shape of the outlet keys. The outlet key of the first model is linear whereas for the second model a curvilinear ogee shape is adopted. Ten discharges between 0.0075-0.03 m3/s and ratio of head over crest to weir height between 0.17-0.58 m were considered for each model. Water surface profiles were plotted along longitudinal and transverse directions at various sections of the PK weir. The effect of the weir geometry on discharging capacity was studied and it is found that the PK weir with curvilinear shaped outlet key is hydraulically more efficient than the linear shaped key. The coefficient of discharge of PK weir with curvilinear shaped outlet key is 12.41-18.15% more than the linear shaped key.

description: We develop Bayesian models for density regression with emphasis on discrete outcomes. The problem of density regression is approached by considering methods for multivariate density estimation of mixed scale variables, and obtaining conditional densities from the multivariate ones. The approach to multivariate mixed scale outcome density estimation that we describe represents discrete variables, either responses or covariates, as discretised versions of continuous latent variables. We present and compare several models for obtaining these thresholds in the challenging context of count data analysis where the response may be over- and/or under-dispersed in some of the regions of the covariate space. We utilise a nonparametric mixture of multivariate Gaussians to model the directly observed and the latent continuous variables. The paper presents a Markov chain Monte Carlo algorithm for posterior sampling, sufficient conditions for weak consistency, and illustrations on density, mean and quantile regression utilizing simulated and real datasets.

description: This master thesis explores the widespread use of the concept of differentiation and related assessment tools, and whether these concepts and measurements can be reliably and validly used for second-generation Arab immigrants. This qualitative study focuses on Bowen’s concept of differentiation, and in particular using the revised version of the Differentiation of Self Inventory (DSI-R). The purpose of the study is to learn more about how second-generation Arab immigrants experience differentiation and how they perceive specific items in the DSI-R. To gather the data, interviews were conducted with 10 second-generation Arab immigrants, followed by the completion of the DSI-R. Follow up interviews were conducted based on the results of the DSI-R to better understand their experience of differentiation, as well as the scale. The interviews were transcribed and analyzed, and four meaning units were extracted from the data: decision making, connection, self, and duality. These themes will be helpful in better understanding this population’s experience of differentiation and its relevance to them, and will help inform culturally-sensitive approaches to psychotherapy.

description: Abstract: In early 1999 the conflict in Kosovo led to the apocalyptic scenario of NATO-sanctioned bombings of the former Federal Republic of Yugoslavia. One of the targets was the complex of buildings comprising the military headquarters in Belgrade: the Generalštab. Over the past twenty years no intervention has been made to repair and protect this cultural monument damaged by war, but its mental image has inevitably changed, transgressing the identity of the historical event. The drawing project The Generalštab Building as Image: A History Decomposeddeals with an aesthetic reflection on political bodies and conditions, asking how they have re-territorialised the material reality of the Generalštab building as a cultural artifact into the performativity of its political function. Keywords: War, cultural monument, visual narratives, perception.

description: A major issue with weirs over erodible beds is the scour downstream, which can seriously challenge their stability. This paper presents experimental results on trapezoidal type-A piano key weirs having two values of bottom slopes keys (28o and 47o). Experiments were conducted in a recirculating channel 10 m long, 0.75 m wide and 0.8 m high. Approach flow depths in the range of 0.032 to 0.07 m, and tailwater depths in the range of 0.08 to 0.18 m were evaluated. It was observed that the bottom slope of weir keys significantly influences the scour depth, such that a 67.8% increase in the slope, increased the average maximum scour depth by about 65%. The maximum scour depth occurred downstream of the outlet keys. Moreover, the scour increased with an increase in the approach flow depth and decreased with the tailwater depth. Distance of location of the maximum scour depth from the weir toe, and length of the scour hole in the weir with key bottom slope of 47o were respectively 5 and 21% greater than the weir with key bottom slope of 28o. In general, the geometric dimensions of the scour hole which were influenced by tailwater depth were more obvious in the model with smaller key bottom slope, such that with a 125% increase in the tailwater depth, the average variations of the scour parameters (maximum scour depth, its distance from the weir toe, and the scour hole length) in the model with smaller key bottom slope were respectively 1.5, 2.5 and 2.7 times those of the other model.

description: The body of work by British architect Cedric Price (1934–2003) is largely concerned with architecture’s relationship to technology and its impact on society. As contemporary architecture finds itself confronted with similar issues today, Price’s designs are being revisited and hailed for their prospective and inventive visions. As such, it seems timely to ask if Price’s designs can be regarded as precedents for future projects that aim to couple participation and technology through architectural design. In this article, I depart from the economic logic of today’s digital platforms to analyse the participatory elements Cedric Price designed for Oxford Corner House (1965–66) to be ‘self-participatory entertainment’. As user participation has gradually been capitalised on through the evolution of digital technologies, I argue that the conditions for what participatory architecture entails have changed in turn. Whereas Price regarded the transfer of information as an activity for users of the Oxford Corner House to engage with freely, the operation of today’s digital platforms instead suggests that such activities are entirely facilitated in order to retrieve information from its users. In order to make this argument, I look at how Cedric Price envisioned digital technologies to sustain participation and in turn how he understood the concept of user participation and its relation to the architectural programme.

description: Controlling the shape and structure of metallic colloids is an important topic. Here, different morphology-structures of colloidal gold particles are investigated with different process parameters in a pulse-based electron-photon and solution interface process. Different tiny-shaped particles of gold developed for different packets of supplied nano-energy as per set pulse OFF to ON time. Depending on the set ratios of pulse OFF to ON times and pulse polarity, packets of nano-energy bind transitional state gold atoms resting at electronically-flat solution surface that is controlled in their own shapes. Tiny particles of joined triangular shape in each case developed under set tuned ratio of bipolar pulses OFF to ON time. At unipolar pulse, tiny particles in triangular shape developed directly. When the ratio of bipolar pulse OFF to ON time was large, distorted shapes of the particles developed. Geometrical shapes of particles developed under significant ratios of pulse OFF to ON times. When the ratio of bipolar pulse OFF to ON time was 3, particles developed in low aspect ratio. But under the fraction of this ratio, particles tend to develop in high aspect ratio. For longer pulse ON time, structures of smooth elements get developed in width less than inter-spacing distance and forcing energy of travelling photons along the interface to flatten them further. Morphology and structure of tiny particles, nanoparticles and particles are discussed for different process parameters opening multiple routes for materials research and their counterparts. This is the overall attained orientation of electrons in elongated atoms forming colloidal particles of different size and shape maintaining the certain color of their solution under sunlight.

We use this result to show that diagonal-preserving stable isomorphisms of graph C*-algebras or Leavitt path algebras give rise to isomorphisms of the groupoids of the associated stabilised graphs. We deduce that the Leavitt path algebras $L_Z(E_2)$ and $L_Z(E_{2-})$ are not stably *-isomorphic.

The Aging Process Deconstructed: Glucose Production, Cancer Resistance and Longevity

description: The aging process affects all mammals and is typically seen with a gradual decline in overall system functionality. This can affect organ and immune function, resulting in increased susceptibility to diseases such as cancer. There are many theories as to specific mechanisms of longevity; we investigate the neuroendocrine regulation of glucose utilization as a potential mediator. Animal models are valuable tools in our efforts to perform gerontological research. Increased lifespan in rodents and mice has been observed through calorie restriction and single mutations, such as Pit-/- and Proph1-/-. Our results in Snell dwarf mice suggest that the pituitary gland and adipose tissue are part of a neuroendocrine loop that lowers the risk of cancer during aging by reducing the availability of glucose.

description: In the late 1950s the Quickborner Team developed a cybernetics-inspired design methodology for organisations, focusing on information flow, with the aim to fully automate administrative labour and to make the organisation constantly adaptable to unpredictable future challenges. Participant analysis allowed them to quantify communication in an organisation and with that envision a new kind of office space. The so-called Bürolandschaft (office landscape), seemingly-endless, chaotic looking interiors, would allow for efficient information flow. One significant aspect of Bürolandschaft design is the non-hierarchic organisation of workers in teams that were bound to quantified decision-making processes, yet addressed as experts, scientists and creatives, ultimately conditioning them to participate voluntarily in reaching the organisation’s goal without questioning

description: Fitness gymnasiums shape subjects and establish communities. The extraordinary rise in the number of high-end, architect-designed fitness gymnasiums responds to, and accelerates market demand as individuals adapt to societal expectations. Yet going to the gym is not experienced as an external directive. It is felt as a desire to be one’s best, to live fully, to succeed. The central role played by design is to (re)produce the desire to voluntarily subject oneself to regimes of self-control and self-transformation. This article looks at how the diverse architecture and interior design of the fitness gymnasium creates this desire and constructs subject positions. Today’s gymnasiums reference elements of bathhouses, spas, surgical clinics, sanatoria, monasteries, discotheques and nightclubs, factories, homes, clubs, hotels, S&M dungeons, massage parlours, beauty salons, cafés, and, even, art galleries – albeit not all in one space. We analyse the richly diverse aesthetics of several commercial chains of gymnasiums and explore the affective experiences established through the manipulation of atmospheric qualities.

description: The divorce between the disciplines of architectural design and systems engineering in conjunction with the scientisation of comfort-standards encourages a year-round and day-round comfort routine to the contemporary human. In his proposal for Air Architecture, French artist Yves Klein proposes the opposite: an architecture devoid of the responsibility to temper human environs. Mechanical machinery enables an architecture to come, while Klein’s proposal for an Architecture of Air imagines a future adaptive-human. Before the popularisation of interior weather, Native populations employed adaptations, or experience a ‘change of human sensitivity’, much like native plants and animals do in order to survive their environment, much like the transformation that Klein describes. In a world where resource reduction and scaremongering tactics regarding climate change do not accomplish enough, we must think towards a more enriched human existence, for a thriving, strengthened human race. Klein uses architecture to imagine a new, joyful world to come, encouraging human evolution through the employment of playful mechanics.

description: Treating the black hole molecules as working substance and considering its phase structure, we study the black hole heat engine by a charged anti-de Sitter black hole. In the reduced temperature-entropy chart, it is found that the work, heat, and efficiency of the engine are free of the black hole charge. Applying the Rankine cycle with or without a back pressure mechanism to the black hole heat engine, the compact formula for the efficiency is obtained. And the heat, work and efficiency are worked out. The result shows that the black hole engine working along the Rankine cycle with a back pressure mechanism has a higher efficiency. This provides a novel and efficient mechanism to produce the useful mechanical work, and such black hole heat engine may act as a possible energy source for the high energy astrophysical phenomena near the black hole.

Lithologic and Tectonic Controls on Bedrock Channel Form at the Northwest Himalayan Front
Creators: name: Allen, George Henry
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Recognition that channel form reflects a river's ability to erode rock has spawned stream-power models that estimate patterns of incision by approximating energy dissipation within a channel. Most commonly, these models assume channel width exponentially scales with drainage area, in part, because drainage area is easily extracted from digital elevation models (DEMs). However, this assumption is often confounded by local variations in rock strength and uplift rate that cause channel constriction downstream. Here we investigate the morphological response of 10 bedrock channels traversing the Mohand range at the northwest Himalayan front to spatial changes in rock strength and uplift rate. We present a new method to continuously measure and compare channel width, slope, and other hydraulic parameters using satellite image analysis and a DEM. Our results suggest that rock strength importantly influences channel form and that channel width should be explicitly measured when extracting tectonic signals from channel morphology.

description: The term Man, and the humanist tradition which followed from it, have been challenged in feminist, queer, poststructuralist, and postcolonial critiques, which questioned its nature, or even pondered if we are actually human. What we seek in this issue of Footprint is to add to these perspectives cases of what we call radical conditioning, in which some architectures bypass assumed values of humanism and operate under a wholly different set of values, emanating from industrial and post-industrial economies and its technological developments. These architectures dictate the creation of spaces in which the human body has to operate, and to which it needs to adapt in order to survive. The research articles and visual essays included in this issue shed light on the many ways architects, advertently or inadvertently, coalesce with forces intending to condition humans. Unfolding in the study of histories, architectural types, aesthetics, atmospheres, systems, and users, authors propose inquiries along two main directions: the first trajectory highlights the prolific use in spatial design of concepts borrowed from cybernetics and information technology for the conditioning of human behavior through the built environment; the second deals with architecture conditioning the creation of new subjectivities, placing the body as the territory of intervention. Understanding these spaces, in which humans and their artifacts interact in unprecedented ways, could provide architecture with the timely opportunity to challenge our anticipated redundancy, and reconsider its own humanism in order to charge it with new meanings.

description: This issue of Footprint follows a double trajectory. On the one hand, it advances an ambition for architecture historiography. The social sciences have long recognised the need for more comprehensive and inclusive methods for writing history. Among them, comparative literature scholar Mary Louise Pratt’s ‘contact zone’ appears as a useful framework for writing new histories of architecture that recognise the many interrelations that characterise the discipline of architecture. On the other hand, and among many possible contact zones, the issue focuses on studying the architecture competition as a contact zone. The resulting collection of articles, review articles and an interview show how, when seen as a contact zone, the architecture competition emerges as fertile ground for the production of disciplinary knowledge, resulting from exchanges between different cultures. Acknowledging the diverse nature of these cultures, together with the recognition of institutions, legislation and other conceptual frameworks as key elements of architecture as contact zone offers fresh theoretical insight, but also poses unexpected communicative challenges.

description: We use time-domain electromagnetic simulations to determine the spectral characteristics of the Hydrogen Epoch of Reionization Arrays (HERA) antenna. These simulations are part of a multi-faceted campaign to determine the effectiveness of the dish's design for obtaining a detection of redshifted 21 cm emission from the epoch of reionization. Our simulations show the existence of reflections between HERA's suspended feed and its parabolic dish reflector that fall below -40 dB at 150 ns and, for reasonable impedance matches, have a negligible impact on HERA's ability to constrain EoR parameters. It follows that despite the reflections they introduce, dishes are effective for increasing the sensitivity of EoR experiments at relatively low cost. We find that electromagnetic resonances in the HERA feed's cylindrical skirt, which is intended to reduce cross coupling and beam ellipticity, introduces significant power at large delays ($-40$ dB at 200 ns) which can lead to some loss of measurable Fourier modes and a modest reduction in sensitivity. Even in the presence of this structure, we find that the spectral response of the antenna is sufficiently smooth for delay filtering to contain foreground emission at line-of-sight wave numbers below $k_\parallel \lesssim 0.2$ $h$Mpc$^{-1}$, in the region where the current PAPER experiment operates. Incorporating these results into a Fisher Matrix analysis, we find that the spectral structure observed in our simulations has only a small effect on the tight constraints HERA can achieve on parameters associated with the astrophysics of reionization.

description: A sharp-crested circular side orifice is a crucial element when it comes to diverting flow from primary source to its subordinate source. Such a flow measurement instrument technique is of immense value in conservation and evaluation of drainage and irrigation networks. Usually, it is placed towards the side of a channel in order to regulate the flow of the fluid. Traditionally, coefficient of discharge was predicted through regression methods which are time-consuming and lack accuracy. Artificial Intelligence (AI) and its applications in this domain have bridged this gap by providing novel alternative methods which prove much more efficient. Repeated studies have pointed out that AI techniques generally give better results when it comes to a myriad of water variables such as rainfall-runoff, evaporation and evapotranspiration, streamflow, and dam water level changes. Total 261 dataset has been collected from the literature review comprising of the fully submerged orifice and for partially-submerged orifice with varying orifice diameter (D) of 5 cm, 10 cm and 15 cm. This study aims to provide a better estimate of prediction of discharge through circular sharp-crested orifice using Artificial Neural Network (ANN). The ANN model has been deployed to randomly select 80% of the data for training, 15% for validation and remaining 5% for testing. In the ANN model, Lavenberg-Marquardt algorithm was used as back-propagation step to assign weights in order to predict the output. The correlation coefficient (R), mean absolute error (MAE) and root mean squared error (RMSE) for complete data of fully and partially submerged circular side orifice are observed to be 0.9765, 0.0228 and 0.0172 respectively.

description: The higher water levels unanticipated at the time of floods are not generally considered in the design of hydraulic structures. The present study emphasizes the experimental investigation for the characterization of submerged flow regimes downstream of a rectangular sharp-crested weir at three different slopes (0, 0.004, and 0.008) that are possible with a laboratory flume. The classical flow patterns of submerged regimes, namely impinging jet, surface wave, surface jump, and surface jet regime, were analyzed. The experiments were conducted to examine the water profiles and the variations of different parameters, representing surface jumps and surface waves, with a gradual rise in submergence. The range of t/h values (where t and h are the downstream and upstream depths above the crest of the weir) at which these regimes shift from one to another were observed to vary with the slope. The photographs of the patterns of the submerged flow regimes at three different slopes and six variants of discharge were captured, and image analysis was carried out. The profiles were extracted for each submergence level to develop the correlations for various characteristics of surface jumps and waves. With an increase in the submergence, the non-dimensional lengths of the surface jumps decreased at all the slopes and were within a range of 10 to 55, whereas the non-dimensional heights increased and were within a range of 0 to 0.7. The surface wave with a maximum normalized amplitude of 0.6 and a maximum normalized wavelength of 4 faded out gradually as the regime ends.
title: A Novel Dual Inlet Tangential Vortex Drop Shaft: An Analytical and Numerical Study

description: Urban drainage systems are undergoing substantial upgrades to enhance resilience to increased urbanisation, population growth and more intense rainfall events. Typically, in these hydraulic structures, the challenge of dropping water flows over significant elevation differences is overcome using vortex drop shaft structures. Many options are available for transferring flows from a single upstream channel to a lower level using independent vortex drop shafts. However, there are many cases where a manhole is to convey discharge from multiple flow inlets. In this work, a novel dual inlet tangential vortex drop shaft was developed during a full-scale commercial project proposal. The paper presents analytical and multiphase numerical modelling studies of various geometries of the structure. Analytical methods were used to derive conditions to maximize the free drainage discharge of inlets and were tested using a three-dimensional multiphase numerical model. The performance of the structure was evaluated for two drop tube diameters with scenarios including (1) equal flows in symmetric inlets, (2) unequal flows in asymmetric inlets and (3) independent inlet flows. The results demonstrate that the analytical model overestimates the free-drainage discharge. Nonetheless, interaction between flows and opposing inlets in the design did not appear to pose any significant stability or performance issues. Moreover, when tested at extreme flow rates up to flooding conditions, the numerical results demonstrate that the vortex air core remains intact. To conclude, a cost-benefit analysis of this type of configuration is presented which provides an economic argument for consideration of the dual inlet drop shaft in future schemes.
The Architecture Competition: A Beauty Contest or a Learning Opportunity?

description: The architecture competition is a high point of interaction between very diverse actors, architecture specialists or not. However, is it really an opportunity for exchange and shared learning? Based on surveys conducted in France and in several European countries on behalf of the French Ministry of Culture, this contribution aims to identify the conditions that foster the interactions inherent to competitions, the possible scope of these exchanges and the rationale behind them. When the competition is a chosen procedure, it is most often perceived as a moment of generating ideas that opens a professional debate and also addresses the general public. When it is mandatory, the competition is guided by another logic: that of ensuring the fairness and transparency of the joint choice of a project and a service provider as well as the legality of the contract concluded with the latter. Depending on the place given by decision-makers to this legal and contractual dimension, the nature and scope of the debates around the competition vary widely. If the legalistic approach dominates, it tends to limit interactions. However if the contracting authority adopts a more open approach to the competition, from programming to the dissemination and capitalisation of its results, it can make a real process of collective deliberation and favour the growth of shared competence.

Competition Juries as Intercultural Spaces

description: In this article, design competitions, as they are practiced in Canada, are understood as devices that allow the study of interdisciplinary and intercultural dimensions of architecture. From the construction of the brief to the selection of the winning project, competitions are exemplary platforms for communicating design values. For example, competitor project proposals, which comprise many qualities, including constructive, material, and even political, represent the priorities of each design team, in the form of a place. Jurors debate each of these qualities through their own expertise. In their search for excellence, the competition jury is then an exemplar contact zone. By examining the various documents produced in this process, we can uncover the value systems of the many stakeholders. Observations of jury deliberations and analyses of jury reports can help expose how the diversity of jurors influences the selection of the winning project. Furthermore, in a contemporary context where environmental design is at the forefront, this diversity is especially interesting to study. An environmental expert’s evaluation of quantitative eco-measurements is very different from an architect’s judgment of spatial qualities and experiences. The focus of this article is to understand how such a variety of jurors influences the competition outcome.

description: Motivated by recent nuclear magnetic resonance (NMR) experiments, we present a microscopic sp3 tight-binding model calculation of the NMR shifts in bulk Bi2Se3, and Bi2Te3. We compute the contact, dipolar, orbital and core polarization contributions to the carrier-density-dependent part of the NMR shifts in Bi209, Te125 and Se77. The spin-orbit coupling and the layered crystal structure result in a contact Knight shift with strong uniaxial anisotropy. Likewise, because of spin-orbit coupling, dipolar interactions make a significant contribution to the isotropic part of the NMR shift. The contact interaction dominates the isotropic Knight shift in Bi209 NMR, even though the electronic states at the Fermi level have a rather weak s-orbital character. In contrast, the contribution from the contact hyperfine interaction to the NMR shift of Se77 and Te125 is weak compared to the dipolar and orbital shifts therein. In all cases, the orbital shift is at least comparable to the contact and dipolar shifts, while the shift due to core polarization is subdominant (except for Te nuclei located at the inversion centers). By artificially varying the strength of spin-orbit coupling, we evaluate the evolution of the NMR shift across a band inversion but find no clear signature of the topological transition.
