description: Over the past fifteen years most advanced education programmes within Schools of Architecture have been questioning the parameters and requirements of doctoral research both in terms of content and form. This double issue of Footprint was motivated by the question of where the field stands today. Footprint 10|11 presents nine contributions from both recently defended and developing PhD candidates from a variety of institutions. The diversity of their work, as well as the similarities found in the submissions, offers a partial view into research topics currently addressed in PhD programmes within Schools of Architecture. In addition to the nine papers by PhD researchers, we have included a paper by Andrew Leach that we believe provides an overview of the general state of contemporary architecture research. Leach makes an appeal to refrain from making all research operational. At a time when the application of research and its economic value seem to form the primary criteria for judging value, this appeal should not be taken lightly.

Wigner transformation, momentum space topology, and anomalous transport

description: Using derivative expansion applied to the Wigner transform of the two - point Green function we analyse the anomalous quantum Hall effect (AQHE), and the chiral magnetic effect (CME). The corresponding currents are proportional to the momentum space topological invariants. We reproduce the conventional expression for the Hall conductivity in $2+1$ D. In $3+1$ D our analysis allows to explain systematically the AQHE in topological insulators and Weyl semimetals. At the same time using this method it may be proved, that the equilibrium CME is absent in the wide class of solids, as well as in the properly regularized relativistic quantum field theory.

A Republican Mirage: Zuber et Cie's Vues d'Amérique du Nord
Creators: name: Gohmann, Joanna M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: In 1834 the French wallpaper company Zuber et Cie, produced a scenic wallpaper titled Vues d'Amérique du Nord, in which scenes of American life unfold across the forty-nine foot composition. Using the popular tropes of viewing spectacles, Zuber et Cie frames American society as a series of five idealized, picturesque vignettes. When considering this wallpaper, there are two levels of spectacle that occur simultaneously: those occurring on the wallpaper's surface and the larger spectacle, which the viewer would have experienced when surrounded by the panoramic-like wallpaper. In this thesis, I examine the layered spectacles, placing the wallpaper within a large context of French interest in America, popular vocabularies of spectacle, and the nineteenth-century French home. Through my analysis, I articulate how and why Vues d'Amérique du Nord was a product of a very specific time in the July Monarchy, during which America was envisioned as the future of France.

description: We present the results of seven Suzaku mosaic observations (>200 ks in total) of the nearest non-cool core cluster, the Antlia Cluster (or Group), beyond its degree-scale virial radius in its eastern direction. The temperature is consistent with the scaled profiles of many other clusters. Its pressure follows the universal profile. The density slope in its outskirts is significantly steeper than that of the nearest cool core cluster (Virgo) with a similar temperature as Antlia, but shallower than those of the massive clusters. The entropy increases all the way out to R_200, which is consistent in value with the baseline model predicted by a gravity heating-only mechanism in the outskirts. Antlia is quite relaxed in this direction. However, the entropy inside ~R_500 is significantly higher than the baseline model, which is similar to many other nearby low mass clusters or groups. The enclosed gas-mass fraction does not exceed the cosmic value out to 1.3R_200. Thus, there is no evidence of significant gas clumping, electron-ion non-equipartition, or departure from the hydrostatic equilibrium approximation that are suggested to explain the entropy and gas fraction anomalies found in the outskirts of some massive clusters. We also present scaling relations for the gas fraction (f_gas,200), entropy (K_200), and temperature (T_500) using 22 groups and clusters with published data in the literature. The enclosed baryon fraction at R_200 is broadly consistent with the cosmic value. The power law slope of the K_200-T_500 relation is 0.638+/-0.205. The entropy deficit at R_200 cannot be fully accounted for by the bias or deviation in the gas fraction.

Avant-Garde, Aestheticization and the Economy
Creators: name: Müller, Michael
Publisher: name: FOOTPRINT
Year: 2011

description: It would very much seem as though the avant-garde in post-war Germany had initially lost sight of the previously politically grounded programmatic narratives. Moreover, it seemed quite obsolete to insist on the destruction of the affirmative. After all, had it not been the Nazis who had pursued such destruction far more successfully than the avant-gardes before them, albeit with completely opposite goals in mind? For this reason, it seemed so compelling to regard the restoration of the avant-garde via the renewed recourse to the autonomy of art as an expression of an anti-fascist stance. The linkage of emancipation of individual subjectivity and radical social change called for by the avant-gardes now collapses once again. In the years that followed, the conservative cultural position repeatedly turned on attempts to closely link aesthetic innovation with social change. This taming of a recalcitrant art was followed in the early 1970s, after a brief intermezzo at the end of the 1960s, by talk of the failure of the avant-garde, before being subjected to outrageous defamation ten years later (particularly in architecture). The question of whether today the universalization of the aesthetic has indirectly realized the hopes of the avant-gardes of an aesthetics of and in lived practice, will be the subject of my remarks.

description: Majorana modes are zero-energy excitations of a topological superconductor that exhibit non-Abelian statistics. Following proposals for their detection in a semiconductor nanowire coupled to an s-wave superconductor, several tunneling experiments reported characteristic Majorana signatures. Reducing disorder has been a prime challenge for these experiments because disorder can mimic the zero-energy signatures of Majoranas, and renders the topological properties inaccessible. Here, we show characteristic Majorana signatures in InSb nanowire devices exhibiting clear ballistic transport properties. Application of a magnetic field and spatial control of carrier density using local gates generates a zero bias peak that is rigid over a large region in the parameter space of chemical potential, Zeeman energy, and tunnel barrier potential. The reduction of disorder allows us to resolve separate regions in the parameter space with and without a zero bias peak, indicating topologically distinct phases. These observations are consistent with the Majorana theory in a ballistic system, and exclude for the first time the known alternative explanations that invoke disorder or a nonuniform chemical potential.

Superstudio 1966-1973: From the World Without Objects to the Universal Grid
Creators: name: Quesada, Fernando
Publisher: name: FOOTPRINT
Year: 2011

description: The Italian group of architects Superstudio entered the architectural scene in 1966 with the exhibition Superarchitecture, an ironical commentary on cornucopia and the consumption of design objects. Between that show and the publication of a serial project called Life, Education, Ceremony, Love, Death in 1973, they developed a thorough critique of design and the professional role of architects in information society. This essay traces the development of Superstudio’s critical project, the evolution of their formal repertoire and their operative instruments, studying their designs, projects and texts.

We show that if $r$ is at least 3 and $A = (A_1,..., A_r)$ is an $r$-tuple of matrices in general position, then up to conjugacy there are only finitely many $r$-tuples of matrices with the same characteristic polynomial as $A$. Equivalently, the locus of determinantal hypersurfaces of degree $n$ in $P^r$ is irreducible of dimension $(r-1)n^2 + 1$.

Between Populism and Dogma: Álvaro Siza’s Third Way
Creators: name: Mota, Nelson
Publisher: name: FOOTPRINT
Year: 2011

description: In the early 1980s, Kenneth Frampton presented critical regionalism as an umbrella concept to frame some peripheral architectural practices that became instrumental to illustrate an alternative approach both to the modernist dogma and to post-modernist reactions. The architecture of Álvaro Siza was one of those marginal practices frequently used to illustrate that alternative position. In this paper I will bring together critical regionalism and its critique to explore the possibility of its role as a mediator between dogmatic applications of the modern canon and populism. Critical regionalism will be discussed within the broader frame of the redefinition of hegemonic relationships, especially postcolonial critique, and the relation centre-periphery. Using Siza’s project for the Malagueira neighbourhood in Évora (Portugal) as support, I will argue that the architect’s approach created a third way between populism and avant-garde, and represents a re-foundation of the avant-garde, where the gap between high culture and the everyday is shortened, through the use of a mediation strategy supported by the architectural project.

We give a new proof of this theorem which shows that it is intrinsically connected with the spectral theory of positive operator semigroups. Our methods also show that some important Perron--Frobenius like spectral results fail to hold in any non-commutative $C^*$-algebra.

Integrating Corporate Social Responsibility Policy in the European Union
Creators: name: Thompson Holmgren, Caitlin Alexandra
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This paper addresses the integration of corporate social responsibility (CSR) policy in the European Union (EU). Although many EU member states have national CSR policies, the EU has been developing a progressive and comprehensive CSR framework. This paper examines what drives CSR activity at the EU level. I define corporate social responsibility as the responsibility of enterprises for their impacts on societies (European Commission, 2011) and examine why a business would choose to engage a CSR policy, and why and how governments choose to support corporate social responsibility as public policy. I find there are multiple benefits to the European Union, including business contributions to sustainable development and public goods, and external benefits of increased normative power. By investigating potential benefits the EU stands to accrue through CSR, we are better informed as to its motivations. We therefore are able to analyze the theoretical explanations that rationalize European CSR outcomes.

description: Despite the tremendous progress in neural radiance fields (NeRF), we still face a dilemma of the trade-off between quality and efficiency, e.g., MipNeRF presents fine-detailed and anti-aliased renderings but takes days for training, while Instant-ngp can accomplish the reconstruction in a few minutes but suffers from blurring or aliasing when rendering at various distances or resolutions due to ignoring the sampling area. To this end, we propose a novel Tri-Mip encoding that enables both instant reconstruction and anti-aliased high-fidelity rendering for neural radiance fields. The key is to factorize the pre-filtered 3D feature spaces in three orthogonal mipmaps. In this way, we can efficiently perform 3D area sampling by taking advantage of 2D pre-filtered feature maps, which significantly elevates the rendering quality without sacrificing efficiency. To cope with the novel Tri-Mip representation, we propose a cone-casting rendering technique to efficiently sample anti-aliased 3D features with the Tri-Mip encoding considering both pixel imaging and observing distance. Extensive experiments on both synthetic and real-world datasets demonstrate our method achieves state-of-the-art rendering quality and reconstruction speed while maintaining a compact representation that reduces 25% model size compared against Instant-ngp.

Discotheques, Magazines and Plexiglas: Superstudio and the Architecture of Mass Culture
Creators: name: Elfline, Ross K.
Publisher: name: FOOTPRINT
Year: 2011

description: This article considers the groundbreaking works of the Italian Radical Architecture collective Superstudio (active 1966–80) with an eye to their complex and contradictory relationship to popular culture. Superstudio’s early pronouncements stating their abstention from building presaged their decision to investigate the radical potential of different non-tectonic mediums culled from consumer culture. Initially, the group embraced popular culture and mass-production for their ability to challenge the hidebound discipline of architecture, leading them to produce an assortment of interior furnishings designed to activate consumers to alter their own living spaces. Later, the group abandoned these pursuits in favour of utopian ‘paper architecture’ projects, simultaneously rejecting the reified consumer object while relying entirely on the magazine as a formal support, a medium fully ingrained in the world of consumerism. Eventually, Superstudio proposed a ‘world without objects’ in which the individual would have a more direct relationship to everyday life by pursuing nomadism and plugging into a networked grid covering the Earth’s surface. Once again, such projects were beholden to advanced information technologies spawned by late capitalism. Studying the neo-avant-garde gambits of Superstudio, therefore, allows us to understand the contradictions inherent in any attempt to contend with popular culture in all its paradoxical forms.

We also show that a large class of HNN extensions or free products, amalgamated over a finite group, admit such an action and we extend our results to groups acting on trees. Finally, we show the ubiquity of finitely generated free dense subgroups of the automorphism group of the Random Graph whose action on it have all orbits infinite.

She Said, He Said: Denise Scott Brown and Kenneth Frampton on Popular Taste
Creators: name: Fausch, Deborah
Publisher: name: FOOTPRINT
Year: 2011

description: During the post-war period, the nature of ‘the people’ and popular culture was a matter of intense interest to the disciplines of architecture and urban design. These issues stand behind a debate between Denise Scott Brown and Kenneth Frampton in the December 1971 issue of Casabella. The disagreement between Frampton and Scott Brown concerns three issues: the nature of ‘the people’, the character of popular culture, and the role of architects in relation to popular culture. Underlying this last issue is the question of popular taste: whether a debased devolution from that of the educated and cultured classes, or an embodiment of its own intrinsic principles. Scott Brown defines the people in terms of a set of ‘subcultures’, diverse groups of persons with relatively uniform sets of behaviours, values, attitudes, and preferences, coexisting together in society. She terms the emerging post-war urban environments ‘the popular landscape’ and claims that the symbolic additions made to homes constitute a source of information about popular values, attitudes, and preferences. Frampton refers to the people in terms such as ‘the constrained masses’, popular culture as ‘engineered fantasies of mass taste’, and the urban landscape as ‘the alienated environment’ of ‘deculturated forms’, a ‘repressed consensus’ of ‘mid-cult kitsch’. The two also disagree about the role of the architect; Frampton is concerned about the loss of a connection of form to content and the reinforcement of alienation and conformity involved in the contemporary approaches to urban design; Scott Brown recommends helping ‘the people’ to ‘live in houses and cities the way they want to live’.

description: Defect Triage is a time-sensitive and critical process in a large-scale agile software development lifecycle for e-commerce. Inefficiencies arising from human and process dependencies in this domain have motivated research in automated approaches using machine learning to accurately assign defects to qualified teams. This work proposes a novel framework for automated defect triage (DEFTri) using fine-tuned state-of-the-art pre-trained BERT on labels fused text embeddings to improve contextual representations from human-generated product defects. For our multi-label text classification defect triage task, we also introduce a Walmart proprietary dataset of product defects using weak supervision and adversarial learning, in a few-shot setting.

Intensity Distribution Function and Statistical Properties of Fast Radio Bursts

description: Fast Radio Bursts (FRBs) are intense radio flashes from the sky that are characterized by millisecond durations and Jansky-level flux densities. We carried out a statistical analysis on FRBs discovered. Their mean dispersion measure, after subtracting the contribution from the interstellar medium of our Galaxy, is found to be $\sim 660\,\rm pc\,cm^{-3}$, supporting their being from cosmological origin. Their energy released in radio band spans about two orders of magnitude, with a mean value of $\sim 10^{39}$ ergs. More interestingly, although the FRB study is still in a very early phase, the published collection of FRBs enables us to derive a useful intensity distribution function. For the 16 non-repeating FRBs detected by Parkes telescope and the Green Bank Telescope, the intensity distribution can be described as $dN/dF_{\rm obs} = (4.1 \pm 1.3) \times 10^3 \, F_{\rm obs}^{-1.1\pm0.2} \; \rm sky^{-1}\,day^{-1}$, where $F_{\rm obs}$ is the observed radio fluence in units of Jy~ms. Here the power-law index is significantly flatter than the expected value of 2.5 for standard candles distributed homogeneously in a flat Euclidean space. Based on this intensity distribution function, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) will be able to detect about 5 FRBs for every 1000 hours of observation time.

description: In this paper, we propose a metric on the space of finite sets of trajectories for assessing multi-target tracking algorithms in a mathematically sound way. The main use of the metric is to compare estimates of trajectories from different algorithms with the ground truth of trajectories. The proposed metric includes intuitive costs associated to localization error for properly detected targets, missed and false targets and track switches at each time step. The metric computation is based on solving a multi-dimensional assignment problem. We also propose a lower bound for the metric, which is also a metric for sets of trajectories and is computable in polynomial time using linear programming. We also extend the proposed metrics on sets of trajectories to random finite sets of trajectories.

Felt Passage: An analysis of the subjective side of time's passage
Creators: name: Blake-Turner, Joanna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: One of the central features of the debate about the nature of time is the supposed fact that time passes, or seems to pass. In this paper, I make explicit two distinct usages of "passage" which go undistinguished in the literature: metaphysical passage (according to which time itself has a dynamic element) and felt passage (according to which time presents itself as dynamic in subjective experience). Felt passage, I note, is notably underrepresented in the literature. Accordingly, I give a thorough analysis of felt passage, identifying four elements of experience that contribute to the subjective experience of passage. To demonstrate the usefulness of this analysis, I focus on the implications of just one of the four elements of felt passage on our understanding both of experience and the temporal sequence.
Bernard Tschumi Draws Architecture!
Creators: name: Hartoonian, Gevork
Publisher: name: FOOTPRINT
Year: 2010

description: Bernard Tschumi’s delineation prepared for the Museu de Arte Contemporânea provides the starting point for this essay, which discusses the historicity of drawing and highlights the horizontality and the verticality that structure architecture’s contrast with the pictorial realm. Juxtaposing a freehand sketch with the digital image of the same project, Tschumi moves to address the paradox concerning the position of the body and drawing. This drawing also speaks for the reversal in the position of the body brought about by digital reproductivity. The reversal alludes to Tschumi’s theorization of architecture in terms of space and event. These, I will argue, are anticipated in The Manhattan Transcripts (1981) where a set of freehand drawings is used to evoke a filmic mood wherein the image is projected parallel to the spectator’s seated position. The essay goes further, suggesting that the theatricality permeating the present architecture is part of the shift from horizontality to the painterly, and yet the phenomenon is not merely a technical issue. Rather, it alludes to architecture’s dialogical rapport with painting at work since the Renaissance.

description: We study the generation of Majorana fermions in a two-dimensional topological superconductor placed in a transverse magnetic field B. A topological insulator/superconductor heterostructure and a two-dimensional p-wave superconductor are discussed. It is demonstrated that in these systems a single vortex creates two Majorana fermions, one hosted at the vortex core. The wave function of the second Majorana state is localized in the superconductor volume along a circle of radius $r^* \propto B^{-1}$ centered at the vortex core. In the case of many vortices, the sensitivity of $r^*$ to the magnetic field B may be used to control the coupling between the Majorana fermions. The latter property could be an asset for quantum computations.

Gravitomagnetism and the significance of the curvature scalar invariants

description: The curvature invariants have been subject of interest due to the debate concerning the notions of intrinsic/extrinsic frame-dragging, the use of the electromagnetic analogy in such classification, and the question of whether there is a fundamental difference between the gravitomagnetic fields arising from the translational and rotational motions of the sources (which have been subject of observational and experimental tests, including the dedicated Gravity Probe-B and LARES space missions). In this work we clarify both the algebraic and physical meaning of the curvature invariants and their electromagnetic counterparts. They are seen to yield conditions for the existence of observers measuring vanishing electric/magnetic fields and gravitoelectric/gravitomagnetic tidal tensors, respectively. We determine these observers (in the gravitational sector and in the presence of sources, for the more relevant gravitomagnetic case) obtaining their velocities explicitly in terms of the fields/tidal tensors as measured by an arbitrary observer. The structure of the invariants of the astrophysical setups of interest is studied in detail, and its relationship with the gravitomagnetic effects is dissected. Finally, a new classification for intrinsic/extrinsic gravitomagnetism is proposed.

description: Architects increasingly favour mapping as a means of documentation. Through maps, they question and define the boundaries of their architectural intervention, the premise being that if they can adequately delaminate and map the site's found conditions, they may achieve a more complex understanding of the said site. If maps can successfully represent sets of complex interactions in an effective manner, they also have an objectifying tendency and are often criticized for being tools of domination as well for their propensity to stabilize space-time. Further, architectural mapping is often associated with the possibility to index the 'designer's syntactical code', a possibility coupled with the idea that 'none of the notations take precedence over any other', so as to encourage 'more plural, open-ended "performances" of the project-in-time'. These positions involve if not a pure scientific objectivity, at least the assumption that one may somehow sidestep the projection of the author's intentionality. Bringing these issues to light, the paper explores whether mapping could address temporality with an assumed depth that would re-responsibilize the architect mapmaker while still remaining open to the users' multiple readings in time. Our contention is that rather than relying on rules, syntax and sequences of transformations, architects may approach mapping as a creative act that is open to different temporalities, involving both a willingness to listen and a readiness to act, allowing stories to emerge all the while stepping up as the narrator. Focusing on the phenomenological dimension of drawing and the epistemological bearings of mapping, the paper reveals some of the ways in which architects can question the relation between architecture and time through their graphic representation.

description: We introduce the preliminary exploration of AniBalloons, a novel form of chat balloon animations aimed at enriching nonverbal affective expression in text-based communications. AniBalloons were designed using extracted motion patterns from affective animations and mapped to six commonly communicated emotions. An evaluation study with 40 participants assessed their effectiveness in conveying intended emotions and their perceived emotional properties. The results showed that 80% of the animations effectively conveyed the intended emotions. AniBalloons covered a broad range of emotional parameters, comparable to frequently used emojis, offering potential for a wide array of affective expressions in daily communication. The findings suggest AniBalloons' promise for enhancing emotional expressiveness in text-based communication and provide early insights for future affective design.

The Woof and the Warp of Architecture: The Figure-Ground in Urban Design
Creators: name: Wortham-Galvin, B.D.
Publisher: name: FOOTPRINT
Year: 2010

description: To borrow a metaphor used by Georg W.F. Hegel in the Philosophy of History to describe historical processes, architecture should be understood as a series of complex threads wherein one recognizes the physical forms as the warp, and the temporal, socio-political, natural, and aural contexts as the woof. Fabric is asserted as a concept broader than the immediate spatial and physical situation in which individual buildings are located; and, the threads of the fabric are all of those elements that aid in making the built environment both a designed and lived experience. In order to discuss this proposed understanding of fabric, this paper will look at how drawings informed the process and theory of urban design in the mid- to late-twentieth century. The discussion will focus on the origins of the Nolli plan and its 'rediscovery' by the Cornell School and their use of the figure-ground as a primary tool in the formulation of an urban design theory. The trajectory of the figure-ground can reinvigorate contemporary urban design praxis once more by reasserting drawing as more than mere illustration but as a means to conceptualize design methodologies that support a holistic notion of fabric.

Premarital life plans during the transition to adulthood in the United States
Creators: name: Coutinho, Raquel Zanatta
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This paper investigates attitudes that never married young adults (ages 17-24) hold about what is important to accomplish before getting married. Using data from the National Study of Youth and Religion (NSYR), I investigate how a range of socio-economic and demographic variables are related to a high degree of importance to particular achievements before marriage. I then provide in-depth narrative of premarital life-plans drawing on qualitative data from semi-structured interviews conducted with a subsample of NSYR survey respondents. As a result, the preparation for marriage is a diverse experience in which young adults form their strategies based on the combination and accumulation of three forms of capital: Human Capital, Identity Formation Capital, and Relationship Capital. The importance of each seems to be structured by important social institutions. Gender, religion, race/ethnicity, geographic location and family are schema-producing and help shaping what young adults think is necessary to be achieved before marriage.
Unidirectional transport of wave packets through tilted discrete breathers in nonlinear lattices with asymmetric defects

description: We consider the transfer of lattice wave packets through a tilted discrete breather (TDB) in opposite directions in the discrete nonlinear Schrödinger model with asymmetric defects, which may be realized as a Bose-Einstein condensate trapped in a deep optical lattice, or as optical beams in a waveguide array. A unidirectional transport mode is found, in which the incident wave packets, whose energy belongs to a certain interval between full reflection and full passage regions, pass the TDB only in one direction, while, in the absence of the TDB, the same lattice admits bi-directional propagation. The operation of this mode is accurately explained by an analytical consideration of the respective energy barriers. The results suggest that the TDB may emulate the unidirectional propagation of atomic and optical beams in various settings. In the case of the passage of the incident wave packet, the scattering TDB typically shifts by one lattice unit in the direction from which the wave packet arrives, which is an example of the tractor-beam effect, provided by the same system, in addition to the rectification of incident waves.

Drawing as Epistemic Practice in Architectural Design
Creators: name: Bovelet, Jan
Publisher: name: FOOTPRINT
Year: 2010

description: The essay deals with drawing as a genuine form of knowledge in architectural design. Drawing is described as an epistemic practice enmeshed with historically changing, material spaces of knowledge. Starting with a brief examination of historic philosophical positions on the epistemicity of drawing, the essay tries to sketch out a tentative heuristic of the epistemic features of drawing from the perspective of symbol and media theory. In the last part, with reference to Nelson Goodman’s distinction between analogue and digital symbol systems, the digitalization of drawing is critically reviewed. The main point is to emphasize that the transformation of drawing into digital drawing formats always consist of a translation. It is crucial to take the challenges stemming from the indeterminacy of translation (W.v.O. Quine) into consideration in order to understand both the epistemic restrictions and the potentials of drawing under the conditions of the rising digital habitat.

Transition programs used to bridge incoming ninth grade at-risk students
Creators: name: Richards, Cassandra N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The purpose of this study was to investigate transitional programs effectiveness for increasing incoming ninth grade student's academics, behavior, and grade promotion in light of effective transitional program components. This study used literature from three programs to identify successful components of transitional programs. The researcher then assessed their level of effectiveness through an analysis of 15 transitional programs. Moreover, the results showed that a successful transition program may or may not use all of the best practices named from literature. However it is clear that the most effective programs pay attention on to activities that increase academic skills, work to improve student behavior, and focus on student's promotion from grade to grade.

description: This issue of Footprint focuses on the post-war years and the negotiation of architecture with an ever more advanced consumer society within the context of welfare state redistributive policies. Industrial, productivist logic is mixed in this era with the biopolitics of the emerging late-capitalist spectacle, and with the shock and awe brought about by the expanding mass-media networks. Many of the contributions to Footprint 8 highlight the need for an alternative to the options spelled out in the last decades in architecture – a ‘radical pragmaticism’ of sorts. Michael Müller, in his diagnostic essay in this volume, outlines the aporia of the current condition of artistic and architectural production, and Isabelle Doucet searches for a theory, while Fernando Quesada, Ross K. Elfline, and Nelson Mota contribute specific precedents of architectural trajectories that were never followed, ranging from Superstudio’s work to Siza’s Malagueira. Deborah Fausch returns to the debate between Denise Scott Brown and Kenneth Frampton in 1971; Isabelle Doucet reviews a book by architecture-activists BAVO, calling for a form of radical pragmatism instead of the polarity of ‘opposition’ and ‘appeasement’; and Maroš Krivý contributes a review of the exhibition Dreamlands at the Centre Pompidou. Consequently, the discussion of the 1960s avant-garde and mass culture leads to an understanding of the challenges contemporary architecture faces and to an outlining of concrete alternatives from the recent past.

description: As an introduction to this issue of Footprint, which is dedicated to questions pertaining to the role, perception and valuation of mass culture and populism within the twentieth century, avant-garde discourse, this text presents a tentative framework that contextualizes and elaborates the questions at hand. It argues that the specific negotiation in the late twentieth century between the architecture discipline and the phenomenon of the consumer society, and especially mass media technologies, introduced a new, hybrid, and at times contradictory disciplinary discourse and practice, which defies the historic avant-garde logic as described by Peter Bürger. The editors argue that the re-investigations of the late twentieth century avant-garde vis-à-vis mass culture lead to a better understanding of the challenges contemporary architecture faces.

Mediated Windows: The Use of Framing and Transparency in Designing for Presence
Creators: name: Gullström, Charlie
Publisher: name: FOOTPRINT
Year: 2010

description: This paper explores the fusion of architecture and media technology that facilitates collaborative practices across spatial extensions: video-mediated spaces. The example presented is a mediated extension of the Museum of National Antiquities in Stockholm to a neighbouring park area and archaeological excavation site in 2008, referred to as a mediated window, or a glass-door. The concepts framing and transparency are used to outline the significance of windows and glazing in architecture and art. The author then considers the potential contribution of architecture in representing the passage from indoors to outdoors and designing for presence. Presence design assumes a contribution from architects to presence research, a currently diversified field, spanning media-space research, cognitive science, interaction design, ubiquitous computing, second-order cybernetics, and computer-supported collaborative work, but in which architecture and artistic practices are less represented. The paper thereby addresses the potential of an extended architectural practice, which incorporates the design of mediated spaces, and outlines presence design as a transdisciplinary practice in which presence research meets architectural design, and spatial and aesthetic conceptual tools, derived from related visual practices, may be productively applied.
