The Work of Art as Monument: Deleuze and the (After-) Life of Art
Creators: name: Schreel, Louis
Publisher: name: FOOTPRINT
Year: 2014

description: In the last chapter of What is Philosophy? Deleuze and Guattari conceptualise the work of art as a paradoxical monument which does not commemorate a past, but rather, preserves itself in the absence of man. The key to understanding this paradox lies in the further determination of the monument as a ‘being of sensations’: a ‘compound’ of ‘percepts’ and ‘affects’, meaning, a composition of invisible forces that populate the world, affect us, and make us become. Art would provoke an encounter with inhuman conditions of life which in daily, pragmatic life are often not given a chance. Yet, why still speak in terms of visibility and invisibility if there is not even an eye to perceive? How to understand a conception of art which refuses to think it in terms of human needs, for example exactly of commemorating the past? Deleuze was well aware of these questions, as the chapter on percept, affect and concept repeatedly re-affirms its radical appeal. In this paper I aim to elucidate this novel understanding of art as unwordly monument. I will do so firstly by looking into its implicit dialogue with the phenomenologists Erwin Straus and Henri Maldiney. Secondly, Theodor W. Adorno's essay 'Valéry Proust Museum' will serve as a ground for formulating what might be called the Deleuzian 'after-life' of art.

description: A numerical method to implement a linearized Coulomb collision operator in the two-weight $δf$ Monte Carlo method for multi-ion-species neoclassical transport simulation is developed. The conservation properties and the adjointness property of the operator in the collisions between two particle species with different temperatures are verified. The linearized operator in a $δf$ Monte Carlo code is benchmarked with other two kinetic simulations, a $δf$ continuum gyrokinetic code with the same linearized collision operator and a full-f PIC code with Nanbu collision operator. The benchmark simulations of the equilibration process of plasma flow and temperature fluctuation among several particle species show very good agreement between $δf$ Monte Carlo code and the other two codes. An error in the H-theorem in the two-weight $δf$ Monte Carlo method is found, which is caused by the weight spreading phenomenon inherent in the two-weight $δf$ method. It is demonstrated that the weight averaging method serves to restoring the H-theorem without causing side effect.

description: We investigate many-body dynamics in a one-dimensional interacting periodically driven system, based on a partially filled version of Thouless's topologically quantized adiabatic pump. The corresponding single-particle Floquet bands are chiral, with the Floquet spectrum realizing nontrivial cycles around the quasienergy Brillouin zone. For generic filling, with either bosons or fermions, the system is gapless and is expected to rapidly absorb energy from the driving field. We identify parameter regimes where scattering between Floquet bands of opposite chirality is exponentially suppressed, opening a long time window in which the system prethermalizes to an infinite-temperature state restricted to a single Floquet band. In this quasi-steady state, the time-averaged current takes a universal value determined solely by the density of particles and the topological winding number of the populated Floquet band. This remarkable behavior may be readily studied experimentally in recently developed cold atom systems.

Affect Theory as Pedagogy of the ‘Non-’
Creators: name: Seigworth, Gregory J
Publisher: name: FOOTPRINT
Year: 2014

description: What is the relationship of affect to the non- of non-philosophy? And how might asking this question also go some distance toward answering (or raising) questions about the continuing relevance of disciplinarity itself? By first taking up minor remarks made by Gilles Deleuze and Felix Guattari in What is Philosophy? – especially around the work of Francois Laurelle – this essay will explore how some of the implications of affect’s relation to the ‘non-‘ intersect with matters of immanence, pedagogy, and, finally, with the resoluteness of disciplinary boundaries.

description: Deep rest-frame optical spectroscopy is critical for characterizing and understanding the physical conditions and properties of the ionized gas in galaxies. Here, we present a new spectroscopic survey called "Metal Abundances across Cosmic Time" or $\mathcal{MACT}$, which will obtain rest-frame optical spectra for $\sim$3000 emission-line galaxies. This paper describes the optical spectroscopy that has been conducted with MMT/Hectospec and Keck/DEIMOS for $\approx$1900 $z=0.1-1$ emission-line galaxies selected from our narrowband and intermediate-band imaging in the Subaru Deep Field. In addition, we present a sample of 164 galaxies for which we have measured the weak [OIII]$λ$4363 line (66 with at least 3$σ$ detections and 98 with significant upper limits). This nebular emission line determines the gas-phase metallicity by measuring the electron temperature of the ionized gas. This paper presents the optical spectra, emission-line measurements, interstellar properties (e.g., metallicity, gas density), and stellar properties (e.g., star formation rates, stellar mass). Paper II of the $\mathcal{MACT}$ survey (Ly et al.) presents the first results on the stellar mass--gas metallicity relation at $z\lesssim1$ using the sample with [OIII]$λ$4363 measurements.

Do CD40L and CD40 Contribute to Sickle Cell Anemia?
Creators: name: Yeboah, Sybil A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: CD40 ligand (CD40L) is an important inflammatory mediator upregulated in inflammatory conditions such as atherosclerosis and sickle cell anemia (SCA). CD40L is expressed on platelets, B cells and epithelial cells, with platelets being its main source. Interaction with its receptor, CD40, has been shown to upregulate adhesion molecule expression, stimulate release of inflammatory molecules and initiate coagulation. These manifestations are also observed in SCA. Previously, our lab reported that the concentration of soluble CD40L ligand in sickle cell patient plasma is 30-fold higher than plasma of normal individuals. Based on these observations, we hypothesize that CD40L and CD40 contribute to SCA by increasing inflammation and blood cell adhesion to the endothelium. To test this hypothesis, we will block the CD40L:CD40 interaction a mouse model of SCA using an anti-CD40L antibody and analyze the effects on lung, liver, spleen and kidney pathology. Furthermore, we will also determine whether this blockade decreases expression of inflammatory mediators such as IL 8 and CD40L. These studies will help to further understand the role of the CD40L:CD40 interaction in SCA, and may eventually help to enhance the overall health of SCA individuals.

Der Detektor wurde im Jahre 2001 installiert und nach der Modifizierung von HERA zur Erreichung hoeherer Luminositaet in Betrieb genommen. Der Backward Silicon Tracker des H1-Experiments wird in Verbindung mit einem Blei-Scintillationsfaser Kalorimeter zur detaillierten Untersuchung der inklusiven tief inelastischen Streuung von Leptonen an Protonen, und der Charm-Erzeugung bei kleinen Werte der Bjorken Variable x eingesetzt. Die guten Eigenschaften von Festkoerper-Halbleitern, geringes elektronisches Rauschen und schnelle Signalantworten, wurden bei der Entwicklung des Silizium Pad-Detektors zum Nachweis von Spuren in der Rueckwaertsregion des H1-Experiments in der ersten Stufe des Triggersystems ausgenutzt. Der neue Triggerdetektor des BST, der Pad-Detektor und die dafuer entwickelte Ausleseelektronik wie auch die implementierte Logik werden beschrieben. Resultate von Teststrahlmessungen und von ersten Messungen unter Luminositaetsbedingungen an HERA-II werden dargestellt.
description: The Backward Silicon Tracker of the H1 experiment is being used in conjunction with a lead-fiber Calorimeter for detailed investigations of inclusive deeply inelastic scattering of leptons from protons, and of charm production at small values of the Bjorken variable x. In this thesis the development of a trigger for the Backward Silicon Tracker is described. The detector was installed in 2001 and started to operate in H1 after the HERA upgrade. Exploiting the low noise performance and fast time response of solid state semiconductors, a silicon pad detector telescope was developed for the first level trigger on tracks scattered in the backward region of the H1 detector. The design of the new trigger part of the BST consisting of silicon pad detectors and dedicated fast readout circuitry is described. Results of beam tests and first luminosity data are presented.

Entrepreneurship

description: “Entrepreneur” is a broad concept which encompasses many types of businesspeople. This dissertation aims to shed light on two distinct forms of entrepreneurs by applying writing, activity, and genre research (WAGR) analysis to two separate entrepreneurial ecosystems. By examining the genre ecologies used by these entrepreneurs to achieve their goals, we can differentiate between them. The WAGR approach employed in this study focuses on three aspects of networks: the participants' goals, their use of genres, and the connections between goals and genre-use. The case studies in this dissertation revolve around two business accelerators; however, these accelerators differ significantly in the types of businesses they support. Spaceworks Tacoma exclusively accelerates art-oriented businesses with fewer than five employees, particularly those owned by entrepreneurs from marginalized backgrounds. These Spaceworks businesses start small and anticipate remaining small. On the other hand, Start-Up Chile (SUP) accelerates businesses centered on disruptive technology with the aim of rapidly scaling into large organizations.
 The key finding of this research is that the entrepreneurs in the case studies not only diverged in their genre-use but also in the goals they sought to accomplish using genres. The most significant genre for microenterprise entrepreneurs in this study was the oral elevator pitch, which aimed to attract new customers. While these microenterprise entrepreneurs were focused on achieving business success, their real priority was improving their community, and this orientation was evident in the genre ecology they employed. On the other hand, high-growth entrepreneurs followed distinct stages where they initially focused on data gathering and iterating their product or service, then shifted their attention to marketing and seeking investment. Genres such as the business plan, business case, and slide-based business pitch, which were scarce or nonexistent at the microenterprise accelerator, were quite popular at SUP. The business pitch served multiple purposes at SUP, including receiving feedback from peers, progressing through the acceleration program, and establishing a reputation. Moreover, apart from genre-use, the objectives of these entrepreneurs were markedly different: the Spaceworks entrepreneurs had a local focus, whereas the SUP entrepreneurs were concerned with industry-level change.
Unamerican Americans: Latina Working-Class Activism in Ybor City, Florida, 1937

description: During the 1930s, the Popular Front mobilized the American working class and reignited the flame of labor organization throughout the nation. This thesis investigates the Popular Front movement in the Latino community, Ybor City, located on the eastern edge of Tampa, Florida. It studies the Popular Front as a social movement rather than a communist movement, and questions the rise of a Popular Front culture despite the absence of the Congress of Industrial Organizations (CIO) in Tampa and Ybor City. This work explores how Floridian Latinos and Latinas used the Popular Front to advance their own platform of workers' rights and become active and participatory citizens in Southern Society. It reconsiders the centralization of white men as the leaders of the Popular Front and uncovers women's activism that defied and challenged traditional gender stereotypes in Tampa, the South, and the United States.
What Will the Architect Be Doing Next? How is the profession of the architect evolving as the focus of society shifts from sustainability to resilience or reactivist-driven design demands?
Creators: name: Mooi, Alexander
Publisher: name: FOOTPRINT
Year: 2014

description: A more engaging and visionary role for architects is emerging, altering focus from a technological advisor to a more sociological engineer or entrepreneur. By researching a selection of current architectural practices an attempt is made to describe this evolution of the architect’s role and to assess if this is truly a new development or even a paradigm shift. Based upon on an analysis of texts by scholars and written conversations with architects on the subject of sustainable architecture, resilient architecture, agency in architecture and reactivist architecture, supplemented with additional statements by architects on the matter of architectural practice, an evolution of this role made clear and put into perspective. The aim of this review therefore is to distil some kind consensus within architectural practice of how the architect’s role is to evolve in the foreseeable future. It appears that reactivist architecture as a descriptive set of principles has absorbed elements of all of the above, becoming more than the sums of its parts and allowing for a new role for the architect to emerge.

How to Think Constructivism? Ruskin, Spuybroek and Deleuze on Gothic Architecture
Creators: name: Swiatkowski, Piotrek
Publisher: name: FOOTPRINT
Year: 2014

description: In the Gothic architecture Lars Spuybroek discovers a vitalist ontology that allows him to rethink the nature of constructivism. The vitalist beauty emerges out of a particular field of material forces and is not an actualisation of a pre-given model. His analysis leads to a critique of the work of Deleuze and Guattari, who are portrayed as philosophers of the sublime. Their resistance to the signifying semiotics leads them too far. They unjustly claim that the Gothic structures emerge due to an affirmation of chaos and not in a careful process of construction. In my paper, I will nevertheless demonstrate that Spuybroek’s critique misses a fundamental point of their analysis. Only phantasms or spiritual becomings - concepts lacking in the analysis of Spuybroek - can allow for a proper appreciation of the Gothic and of the process of construction.

Video Assemblages: ‘Machinic Animism’ and ‘Asignifying Semiotics’ in the Work of Melitopoulos and Lazzarato
Creators: name: Hetrick, Jay
Publisher: name: FOOTPRINT
Year: 2014

description: In this paper I will analyse the theoretical background of a single video installation – co-created by Angela Melitopoulos and Maurizio Lazzarato – in order to unpack Deleuze and Guattari’s important but somewhat elusive concepts of ‘machinic animism’ and ‘asignifying semiotics.’ Assemblages (2010) is a three channel audio-visual documentary about the French philosopher and psychoanalyst Félix Guattari. I will argue that, in order to fully understand this work, we must interrogate the incredibly dense theoretical context it inhabits. In particular, I will explore the juncture between Guattari’s ethico-aesthetic ideas concerning a potential ‘ecosophy’ – or theory of the different relations between humans and nature that depends upon a new semiotics – and Lazzarato’s conception of ‘videophilosophy,’ which is grounded upon a politicised Bergsonian onto-aesthetics. I will conclude by criticizing Nicolas Bourriaud’s misappropriation of Guattari in his book Relational Aesthetics and propose that Assemblages demands quite a different and more radical gesture of relationality: one that follows an ecosophical logic that envelopes and imbricates the different levels of nature, the individual, and the social in a way that we might qualify with the term ‘unnatural participation.’

description: Overlapping Feshbach resonances are commonly observed in experiments with ultracold atoms and can influence the molecule production process. We derive an effective approach to describe magnetoassociation in an external trap in the presence of multiple overlapping resonances. We study how the strength and shape of the trap affects the energy level structure and demonstrate the existence of a regime in which the conventional two-channel Landau-Zener description of the molecule production process breaks down.

description: The plasma membrane (PM) of live cells has a striking phospholipid asymmetry between bilayer leaflets, yet the purpose of this fundamental structure remains elusive. It is also unknown whether and how this phospholipid asymmetry impacts on the lateral organization of the PM, such as microdomains or lipid rafts that are thought to facilitate specific protein-protein interactions. Here, we generated asymmetric giant unilamellar vesicles (GUVs) and found that microdomain formation is inhibited by outer leaflet very long acyl chain (24:0) sphingomyelin (SM), the primary sphingolipid species in mammalian cells. Interestingly, although cholesterol is believed to associate favourably with SM, molecular dynamic (MD) simulations of asymmetric membranes indicate a strong preference for cholesterol in the inner leaflet when 24:0 SM is in the outer leaflet, as well as, interdigitation of 24:0 SM acyl chain across the centre of the bilayer. We thus hypothesized that the outer leaflet-localized 24:0 SM interdigitates across the leaflets of the bilayer and facilitates cholesterol enrichment in the inner leaflet. Indeed, we obtained evidence that, in asymmetric unilamellar vesicles with 24:0 SM exclusively in the outer leaflet, 75-80% of cholesterol was partitioned into the inner leaflet, which was correlated with the disappearance of microdomains in GUVs. Importantly, in live cell PM, where 24:0 sphingolipids are the predominant species and exclusively in the outer leaflet, cholesterol was similarly enriched in the cytoplasmic leaflet. SM with shorter acyl chains such as 16:0, a minor species in mammalian cells, failed to generate cholesterol asymmetry and promoted microdomains in both symmetric and asymmetric GUVs. Furthermore, we generated live mammalian cells with either 16:0 or 24:0 SM and analyzed submicron domains in these cells, using density-dependent FRET of GPI-anchored proteins. Indeed, 16:0 SM cells are capable of forming submicron domains. The 24:0 SM cells, by contrast, are nearly devoid of submicron domains, as are unmodified control cells. Moreover, we silenced ceramide synthase 2 (CerS2), the enzyme that generates very long acyl chain sphingolipids. We found that silencing CerS2 alters diffusional properties of membrane proteins, consistent with enhanced microdomain formation. Together, our results establish a surprising and central role of very long acyl chain sphingolipids in regulating membrane lateral organization, including in the native plasma membrane, by creating cholesterol asymmetry. We propose that sphingolipid asymmetry functions to dynamically regulate microdomains in live cells.

description: We introduce scattering-symplectic manifolds, manifolds with a type of minimally degenerate Poisson structure that is not too restrictive so as to have a large class of examples, yet restrictive enough for standard Poisson invariants to be computable. This paper will demonstrate the potential of the scattering symplectic setting. In particular, we construct scattering-symplectic spheres and scattering symplectic gluings between strong convex symplectic fillings of a contact manifold. By giving an explicit computation of the Poisson cohomology of a scattering symplectic manifold, we also introduce a new method of computing Poisson cohomology.

description: We look for ground state solutions to the following nonlinear Schrödinger equation $$-Δu + V(x)u = f(x,u)-Γ(x)|u|^{q-2}u\hbox{ on }\mathbb{R}^N,$$ where $V=V_{per}+V_{loc}\in L^{\infty}(\mathbb{R}^N)$ is the sum of a periodic potential $V_{per}$ and a localized potential $V_{loc}$, $Γ\in L^{\infty}(\mathbb{R}^N)$ is periodic and $Γ(x)\geq 0$ for a.e. $x\in\mathbb{R}^N$ and $2\leq q<2^*$. We assume that $\infσ(-Δ+V)>0$, where $σ(-Δ+V)$ stands for the spectrum of $-Δ+V$ and $f$ has the subcritical growth but higher than $Γ(x)|u|^{q-2}u$, however the nonlinearity $f(x,u)-Γ(x)|u|^{q-2}u$ may change sign. Although a Nehari-type monotonicity condition for the nonlinearity is not satisfied we investigate the existence of ground state solutions being minimizers on the Nehari manifold.
"The Faster the Machines, the Better the Poetry": Gebhard Sengmüller's TV Poetry
Creators: name: Dickey, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Vienna-based artist Gebhard Sengmüller's 1990s multimedia installation TV Poetry represented a critical and constructive response to television's influence in the late twentieth century, aligning it with a dialectical construction of electronic media in Marxist media theory. The work falls within art historical, literary, and technological lineages of systems, media, and telecommunications art. In its reconfiguration of television's discursive codes and its incorporation of networked engagement, TV Poetry represented an ambivalent acknowledgement of the relationship between cultural consumption and attention, and the potential of software to disrupt the one-way transmissions of broadcast television. The second version of TV Poetry more explicitly engaged a context of communicational borderlessness and growing possibilities for newer media to reconfigure power relations via its simultaneous emphasis on and collapsing of the distances between information transmission and reception, and its disruption of experiences of time and place, real and virtual, watching and reading, and creation and consumption.
Wartime Lessons, Peacetime Actions: How Veterans Like Major-General Dan Spry Influenced Canadian Society After 1945

description: This study examines some of the ways in which Second World War veterans helped shape Canadian society in the years after 1945 by using the life experience of one of their number, Major-General Daniel Charles Spry, as an interpretive model. Just over one million Canadian men and women re-entered civil life after their wartime military service. Representing approximately 35 per cent of Canada’s adult male population aged 25 to 49 in 1951, and found in nearly every facet of Canadian life, Second World War veterans possessed social importance that extended far beyond their experience of the Veterans Charter. Using Dan Spry’s documented thoughts and actions in war and peace, this study argues that a number of these individuals learned lessons regarding leadership, character, citizenship, and internationalism during their wartime military service and – finding them useful – applied such lessons to various aspects of their lives after the war’s end. In so doing, Second World War veterans helped to influence the character of postwar Canada’s institutions, workplaces, and the lives of many Canadians by providing societal leadership, moulding children’s character, developing future citizens, and trying to build a better world. Appreciating their varied contributions provides new insight into both veterans’ attitudes and the sort of place that Canada was after the guns fell silent in 1945.
Excitation spectra of a Bose-Einstein condensate with an angular spin-orbit coupling

Year: 2016

description: A theoretical model of a Bose-Einstein condensate with angular spin-orbit coupling has recently been proposed and it has been established that a half-skyrmion represents the ground state in a certain regime of spin-orbit coupling and interaction. Here we investigate low-lying excitations of this phase by using the Bogoliubov method and numerical simulations of the time-dependent Gross-Pitaevskii equation. We find that a sudden shift of the trap bottom results in a complex two-dimensional motion of the system's center of mass that is markedly different from the response of a competing phase, and comprises two dominant frequencies. Moreover, the breathing mode frequency of the half-skyrmion is set by both the spin-orbit coupling and the interaction strength, while in the competing state it takes a universal value. Effects of interactions are especially pronounced at the transition between the two phases.

Medium Affect Desire: Hybridising Real Virtual and the Actualised through Affective Medium Ecology
Creators: name: Boumeester, Marc
Publisher: name: FOOTPRINT
Year: 2014

description: Underneath the turbulent surface of the ubiquitous media-scape lies an even more agile and aggressive set of relations. A central figure in this turmoil of desires seems to be the asignifying sign, which has a hybridising liaison with both the realm of the real virtual and the realm of the actualised. The main question is what does it want? This new materialistic, non-anthropocentric liberty of affect is creating an arena of strange attractors and other topological vector fields in which our own unconscious drive is as effective as that of the steel ball in a pinball machine. Could we isolate the intrinsic drive of the medium from its subservient position in the aesthetic, freeing its desire from the anthropocentric dominion? What does it Yen for? Perhaps this gap is not meant to be filled, as it is this yearning what it yearns for. The asignifying sign cannot be isolated, it is neither here nor there, yet it is conditionally omnipresent, it inhibits the gap, its desire is to affect.

Moiré Effect: Index and the Digital Image
Creators: name: Baraklianou, Stella
Publisher: name: FOOTPRINT
Year: 2014

description: The moiré effect and phenomena are natural occurring geometric formations that appear during the super-position of grid structures. Most widely recognisable in colour printing practices, generally viewed on screens (computer and TV) they are in most cases examples of interference within a signal or a code, unwanted visual mis-alignment. Especially in digital image capture, moiré patternings appear when a geometrically even pattern, like a fabric or close-up of fine texture, has an appearance of rippled water with blue or red hues of concentric circle formations. The intriguing pattern formation in this case points back not only to the mis-alignment of frequencies, but can be further seen as the intersection point of a speculative ontology for the index of the digital image. Moiré not only as a visually reproducible phenomenon or effect, but a field of vision that blurs the boundaries between analogue and digital, perception and affect, manifesting the photographic as a constant site of becoming, a site of immanence. The philosophy of Henri Bergson, Brian Massumi and Francois Laruelle will be explored alongside the moiré image and phenomenon, to see if there is such a speculative site underlining the becoming of the digital image and its repercussions in contemporary digital culture.

description: The aim of the article is to understand more about the potentials of citizen participation in planning. The research project in focus was conducted in a stigmatised Swedish context and was participatory in approach, including local interaction activities, case-based participant observation and key informant interviews. The project aim was to develop knowledge about the interplay between top-down invitations for dialogue and bottom-up citizen initiatives. Two cases are discussed in relation to previous research on participation. The participatory process was shown to influence how ‘socially responsible public procurement’ of a construction project was carried out, and hence the article concludes that citizen participation in design can influence systems and procedures. The question of how such knowledge and awareness can develop the planning profession ends the article.

description: We use the effective field theory of dark energy (EFT of DE) formalism to constrain dark energy models belonging to the Horndeski class with the recent Planck 2015 CMB data. The space of theories is spanned by a certain number of parameters determining the linear cosmological perturbations, while the expansion history is set to that of a standard $Λ$CDM model. We always demand that the theories be free of fatal instabilities. Additionally, we consider two optional conditions, namely that scalar and tensor perturbations propagate with subliminal speed. Such criteria severely restrict the allowed parameter space and are thus very effective in shaping the posteriors. As a result, we confirm that no theory performs better than $Λ$CDM when CMB data alone are analysed. Indeed, the healthy dark energy models considered here are not able to reproduce those phenomenological behaviours of the effective Newton constant and gravitational slip parameters that, according to previous studies, best fit the data.

Learning from Failures: Architectures of Emergency in Contested Spaces (Pyla, Cyprus)
Creators: name: Stratis, Socrates
Publisher: name: FOOTPRINT

description: One of the characteristics of contested spaces of ethno-religious origin is the failure to work around common projects. This is the case of the community of Pyla, Cyprus, one of a few inter-ethnic communities on the island. Architectural and planning practices are urged to contribute to the process of reconciliation, despite the lack of an on-going official reconciliation process, and their lack of power. Recently, there has been an increasing number of practices in Cyprus that re-examine their field of operation and readjust their design tools accordingly. One of them is the Architectures of Emergency initiative, in which the author participates, which employs characteristics of ‘first aid’ architecture by inserting moments of publicness into the void created by the absence of a common institutional framework between the two communities.

Generative and Participatory Parametric Frameworks for Multi-player Design Games

description: Generative design processes have been the focus of current architectural research and practice largely due to the phenomenon of emergence explored within self-organisation, generative grammars and evolutionary techniques. These techniques have been informing participatory urban design modalities, which are investigated in this paper by critically reviewing theories, practices, and (software) applications that explore multi-player online urban games, with respect to not only their abilities to facilitate online trans-disciplinary expert collaboration and user participation but also to support implementation of democratic ideals in design practice. The assumption is that even if generative and participatory parametric frameworks for multi-player design games may not replace politics as a discipline concerned with the study of government and policies of government, they may reduce the bureaucratic apparatus supporting government by establishing a direct interface between experts such as politicians, urban planners, designers, and users.

description: The Tallinn Architecture Biennale ʻRecycling Socialismʼ, held in September 2013, is reviewed in this paper. Key themes and contradictions that crystallised throughout the event are identified and analysed. Participatory approach and its shortcomings are discussed in relation to the Biennaleʼs vision competition winning entry. What is the dual legacy of socialism and modernism for architectural and urban practices? The question is studied via the contrasting practices of raumlabor and DOGMA, two key participants in the Biennaleʼs events. Whereas participation is a goal and an answer to modernist-Fordist city in raumlabor's practice, for DOGMA it is the starting point for interrogating post-Fordist city.

Novice Teachers of English: Participation and Approach to Teaching in School Communities of Practice in Chile
Creators: name: Romero, Gloria
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2017
Subjects: Novice teacher
Participation
Community of practice

description: The first years in the teaching profession are challenging, unforgettable, and shape the professional development of novice teachers. This study aimed at exploring the participation experiences of novice teachers in English teaching communities of practice and examining if this participation influenced their reported approaches to teaching English. Wenger, McDermott and Snyder’s theory of communities of practice was used and data was collected from online close and open-ended surveys, interviews, and staff meeting observations. The findings show that, independently of the social background of students and the financial resources of different school contexts, community support has a direct impact on the quality of the practices of novice teachers in CoPs, their participation and integration in the communities, and their reported approaches to teaching English. Moreover, in supportive contexts, NTEs’ approach to teaching was communicative-focused because their communities allowed them to experiment with language and try new ideas. This study extends the work of Wenger, McDermott and Snyder on organisational and managerial communities by providing insights into the field of second language education. Furthermore, it extends the work of scholars with novice teachers in English language teaching by addressing the socioeconomic aspect of their experiences and by connecting community support directly to the approaches to teaching of novice teachers. This research offers insights to novice teachers on the practices carried out in English teaching communities in the Chilean context and offers experienced teachers the opportunity to reflect on how they treat and work with novice teachers.

description: This issue of Footprint examines the notion of asignifying semiotics, which plays a dominant role in contemporary capitalism and becomes indispensable in creating the very conditions for its political critique. Asignifying semiotics is not limited to the semiotics of mathematics, stock indices, money, accounting and computer codes, but includes the semiotics of music, art, architecture, film, dance, and so on. What they have in common is their repudiation of the hegemony of meta-languages. Asignifying signs do not represent or refer to an already constituted dominant reality. Rather, they simulate and pre-produce a reality that is not yet there. Existence is not already a given, it is a stake in the experimental assemblages, be they scientific, political or artistic. Deleuze and Guattari’s principle of asignifying rupture calls for relinquishing the tautological, and hence trivial effort of tracing, in favour of creative mapping. The ten articles in Footprint 14 constitute a cartography that is coextensive with the social field, no longer as mimesis but as poiesis. Issue's editors: Deborah Hauptmann and Andrej Radman

description: We derive a posteriori error estimates for a semi-discrete finite element approximation of a nonlinear eddy current problem arising from applied superconductivity, known as the $p$-curl problem. In particular, we show the reliability for non-conforming Nédélec elements based on a residual type argument and a Helmholtz-Weyl decomposition of $W^p_0(\text{curl};Ω)$. As a consequence, we are also able to derive an a posteriori error estimate for a quantity of interest called the AC loss. The nonlinearity for this form of Maxwell's equation is an analogue of the one found in the $p$-Laplacian. It is handled without linearizing around the approximate solution. The non-conformity is dealt by adapting error decomposition techniques of Carstensen, Hu and Orlando. Geometric non-conformities also appear because the continuous problem is defined over a bounded $C^{1,1}$ domain while the discrete problem is formulated over a weaker polyhedral domain. The semi-discrete formulation studied in this paper is often encountered in commercial codes and is shown to be well-posed. The paper concludes with numerical results confirming the reliability of the a posteriori error estimate.
