Curator As Lead Artist

Year: 2017
Subjects: Curatorship

description: My thesis research methodology investigates the spaces between curatorial and artistic practices. More specifically, I am interested in the boundaries and slippages between these separately defined disciplines, and the potential that exists in testing points of crossover and confusion. With this in mind, this thesis considers the curator as collaborator as artist position, to explore beyond the conventional expectation that artists make works of art which curators then display. Through my work, I attempt to demonstrate the opportunities and challenges that arise when curators take on increasingly authorial and creative roles in both the production and presentation of the work of others. Carolyn Christov-Bakargiev, a curator who has in the past refused to use this professional designation, notes that “the curator is the most emblematic worker of the cognitive age” (Balzar 9). Christov-Bakargiev’s quote is an important place to begin my research because although she acknowledges that curators are significant, she hesitates to identify as one, demonstrated by her use of the term agent and such (Judah). If curators are at the forefront of cultural production, where does that put the artists? This thesis project is a way to investigate, through creative and material practice, the historical and contemporary discourse around a specific type of relationship between curating and art making: the area where the labour of curators and artists intersects. Additionally, it attempts to blur and reframe the ethical questions raised specifically regarding issues of authorship, artistic responsibility, collaboration, and contextual engagement. In our spectacle driven culture with a multitude of content readily available, we increasingly value those able to reshape, select, and organize this content in generative ways. New modes of practice, organized around the position of a kind of lead artist or curatorial artist, provide a critical space for rethinking the possibilities of making, postproduction, representation, and display.

description: In this paper a quantum mechanics is built by means of a non-Hermitian momentum operator. We have shown that it is possible to construct two Hermitian and two non-Hermitian type of Hamiltonians using this momentum operator. We can construct a generalized supersymmetric quantum mechanics that has a dual based on these Hamiltonians. In addition, it is shown that the non-Hermitian Hamiltonians of this theory can be related to Hamiltonians that naturally arise in the so-called quantum finance.

An exploratory study in conceptualizing children's investigatory activities of natural phenomena by utilizing Thomas S. Kuhn's view of science as a theoretical framework
Creators: name: Lindberg, Wayne Charles
Publisher: name: University of British Columbia
Year: 2011

description: The study, by exploiting Thomas S. Kuhn’s view of scientific development, attempted to establish a theoretical basis for teaching and learning science in the classroom. At the present preliminary stage of the exploratory study, the writer concentrated on Kuhn's historical pattern of science in which paradigms form research traditions separated by scientific revolutions resulting in new and more sophisticated views of the field. The writer felt that the acquisition of views of natural phenomena by children might follow some sort of evolutionary, Kuhnian-like pattern of paradigmatic investigatory activities. These activities would be separated by transitional periods of effort or paradigm-like shifts resulting in new and incommensurate ways of seeing natural phenomena. To facilitate the recognition of such a pattern of intellectual behaviour by children, the writer formulated a teacher role based on ideas drawn from Kuhn. The present study attempted to provide apparent examples of children's modes of thought and speculative bases: for some of their actions. By observing children's investigatory activities, involving sinking and floating objects, the writer found some support for what he has termed child-paradigms or points of view about natural events. All children, for example appeared to hold a child-paradigm that objects sink when filled with water. Support was also found for Kuhn's suggestion that children's views often show striking parallels to those of Aristotelians. In this case, the learners appeared to see water as an external, Aristotelian-like, motive force which causes objects to sink or move from their natural floating positions. During the course of their activities, all children appeared to encounter numerous novel observations or anomalies -- facts and findings inconsistent with their expectations. Applying the point of view that objects sink when filled with water, all learners discovered that the plastic straw floated. The assimilation of anomaly, in one instance, resulted in what has been termed a child-paradigm shift. During this experience the child's earlier view that floating objects do not displace water was replaced by a more sophisticated view involving water displacement. Although only one child-paradigm shift or perceptual-conceptual transposition seemed reasonably evident in the study, the writer felt that this concept was useful in accounting for children's acquisition of modern scientific views. He speculated that a modified teacher role could facilitate shifts in children's perception. In addition, he speculated about the potential usefulness of the study for classroom teaching and suggested several problems for future investigation related to curriculum development.

description: This paper examines the concept of materiality and how my work engages it. In line with art historian Edward J. Sullivan, I approach materials as potential objects functioning as cultural signifiers. I explore the idea of material through Monika Wagner’s approaches as active matter that is full of energy. That means that materials do not need to be handled by human hands in order to be activated; they have the power to speak by themselves. The selection of materials I make to develop the project focuses on fabrics and garments used in the language of decoration. This decision is driven by my interest and observation of ornamentation in architecture and home decoration. Through ornamentation I explore the tension I find in the relationship that we have as subjects with culture and nature. In this tension, I scrutinize the need of humans to control almost everything around them. I inspect the actions and signs imbed in ornamentation to exert control. In order to narrow the point of reflection I bring up memories from my Catholic childhood to exemplify the sources of nourishment and support the visual language that I develop. I draw on Sir Ernst Gombrich in order to illuminate the psychology of the ornamentation and problematize nature-culture dualities. Gombrich remarks that the need for ornamentation is connected with our biological inheritance. Our cognitive system requires ways to order and systematize so as to create states of comfort and tranquility. This modus operandi is applied to every aspect of our life. I parallel this need to control with colonialism. Along with the material exploration and the attempt to disrupt the tendency to order and control, I study Gretchen E. Henderson’s approach to the idea of ugliness as “matter out of place”, and also to Ernst Jensch’s understanding of “the uncanny” as something unusual that causes confusion. These are the strategies and methods I apply to the materials to create uneasiness and alter viewer’s perception. Ultimately, my intention is to provoke viewers’ curiosity to explore ways of seeing outside of the paradigm that controls them.

description: This document expresses a theoretical and practical description of my research and studio practice. I engage in mining and querying historical and political archives, specifically those documenting the North American Women’s Liberation Movement of the late 1960s to early 1970s. Images and text are collected, then re-presented through the act of hand drawing, furthered by layering and assembling the resulting images to stimulate embedded strategies of resistance and subjectively understand the affect of those positions in the present. A direct interest in themes of potentiality, possibility and the ability to visually and physically express these notions frames my practice. In short, through this work I am asking what are the capabilities of revisiting historical images as sites for latent possibilities of collective engagement? Drawing returns these images to the present, and therefore asks the viewer to reconsider the hopes and failures of the past, the ideals and goals not-yet-realized. The ultimate installation strategies of this work: fragmented, rearranged, layered and reorganized simultaneously seek to crowd the viewer in multiple drawing events, eliciting the sentiment of the crowd, the mass, and re-emphasizing the individual. Ultimately my practice engages in multiple temporalities – past, present and future, through a careful and embodied practice of observation, deliberation, and generative translation.

description: We propose a simple one-dimensional spin-2 Hamiltonian, which exhibits two topologically distinct valence bond solid states in different exactly solvable limits. We then construct the phase diagram and study the quantum phase transition between these states using the infinite time evolving block decimation algorithms. From the scaling relation between the entanglement entropy and correlation length, we find that the central charge for the underlying critical conformal field theory is $c=2$.

description: The article discusses the productivity disparity between developed and developing countries since the 1970s, attributing it to differences in capital intensity and qualifications. Despite a strong scientific foundation, there is a notable weakness in technological innovations in developing nations, reflected in low R&D, patents, and a lag in adopting advanced practices. The document emphasizes technological innovation as a key driver of economic growth, exploring the concept of "uncertainty" in the search for new technologies and its impact on both developed and developing economies.

A min-type stochastic fixed-point equation related to the smoothing transformation

description: This paper is devoted to the study of the stochastic fixed-point equation X \stackrel{d}{=} \inf_{i \geq 1: T_i > 0} X_i/T_i and the connection with its additive counterpart $X \stackrel{d}{=} \sum_{i\ge 1}T_{i}X_{i}$ associated with the smoothing transformation. Here $\stackrel{d}{=}$ means equality in distribution, $T := (T_i)_{i \geq 1}$ is a given sequence of nonnegative random variables and $X, X_1, ...$ is a sequence of nonnegative i.i.d. random variables independent of $T$. We draw attention to the question of the existence of nontrivial solutions and, in particular, of special solutions named $α$-regular solutions $(α>0)$. We give a complete answer to the question of when $α$-regular solutions exist and prove that they are always mixtures of Weibull distributions or certain periodic variants. We also give a complete characterization of all fixed points of this kind. A disintegration method which leads to the study of certain multiplicative martingales and a pathwise renewal equation after a suitable transform are the key tools for our analysis. Finally, we provide corresponding results for the fixed points of the related additive equation mentioned above. To some extent, these results have been obtained earlier by Iksanov.

Survival of microorganisms under conditions of total starvation
Creators: name: Potts, Joy Margaret
Publisher: name: University of British Columbia
Year: 2011

description: Aerobacter aerogenes was shown to accumulate large quantities of a glycogen-1ike polysaccharide when grown under conditions of nitrogen deprivation and carbon excess. The majority of the reserve material was rapidly degraded during incubation in a non-nutrient medium; however, a decrease in carbohydrate to the structural level was obtained only after a four-day starvation period. Cells possessing the energy reserve compound contained a substantially reduced ribosomal complement relative to carbon-limited A. aerogenes and Pseudomonas aeruginosa which did not store this material. Ribosomes were degraded during starvation to barely detectable levels. In the non-nutrient environment, various intracellular components were degraded. Glycogen was the primary substrate for nitrogen-limited A. aerogenes, ribonucleic acid (RNA), for carbon-limited A. aerogenes and protein for nitrogen-limited P. aeruginosa. Correlating with the preferential utilization of RNA by carbon-limited A. aerogenes was the ability of this organism to oxidize ribose, one of the degradation products of RNA metabolism. P. aeruginosa was unable to degrade ribose but could efficiently oxidize most of the common amino acids and, therefore, protein was presumably the primary substrate during the endogenous metabolism of this organism. Survival curves of cells respiring endogenously revealed that glycogen-rich A. aerogeiies remained almost completely viable over a 24 hr. period of starvation whereas glycogen-deficient A. aerogenes or P. aeruginosa did not. However, once the rapid death rate of Aerobacter was initiated, the process continued until less than 1% of the original population remained viable. Conversely, although the death rate of P. aeruginosa was initially very fast, the number of viable cells at no time decreased to less than 6% of the original viable number. Alterations in the rates of transport of metabolites in A. aerogenes and P. aeruginosa did not correlate with maintenance of viability, as determined by the ability of cells to form colonies on plate count agar. It was concluded that the capacity to store a carbonaceous energy reserve is obviously a biological advantage to Aerobacter aerogenes. However, the ability of Pseudomonas aeruginosa to catabolize a wide range of substrates, coupled with the maintenance of its transport systems, must be more physiologically advantageous for the survival of a species than the ability to store carbonaceous reserves under certain limited growth conditions.

description: We have used time-resolved x-ray photoemission electron microscopy to investigate the magnetization dynamics induced by nanosecond current pulses in NiFe/Cu/Co nanostripes. A large tilt of the NiFe magnetization in the direction transverse to the stripe is observed during the pulses. We show that this effect cannot be quantitatively understood from the amplitude of the Oersted field and the shape anisotropy. High frequency oscillations observed at the onset of the pulses are attributed to precessional motion of the NiFe magnetization about the effective field. We discuss the possible origins of the large magnetization tilt and the potential implications of the static and dynamic effects of the Oersted field on current-induced domain wall motion in such stripes.

description: We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical electronic response of valence electrons. Our results indicate that the finite width of the plasmon resonance, which is mainly due to the presence of band-structure effects, strongly modifies the asymptotic behaviour of the energy loss at large distances from the surface. This effect is relevant for the understanding of the interaction between charged particles and the internal surface of microcapillaries.

Through my practice of archive and image space deconstruction I investigate the ability of images to be traces of collective history and tangible representations of memory. My practice uses a feminist auto-ethnographical approach to challenge the notion that archives are assembled with objectivity. I deconstruct and fragment my own family archive as a way to address the way in which our preconceptions of photographic truth can lead to misrepresentations of identity and memory.

description: Recently, weak measurements were used to measure small effects that are transverse to the propagation direction of a light beam. Here we address the question whether weak measurements are also useful for measuring small longitudinal phase shifts. We show that standard interferometry greatly outperforms weak measurements in a scenario involving a purely real weak value. However, we also present an interferometric scheme based on a purely imaginary weak value, combined with a frequency-domain analysis, which may have potential to outperform standard interferometry by several orders of magnitude.

Common misperceptions of the events relating to the rise of the protest movements on the prairies
Creators: name: Sanguinetti, Sonja Patricia
Publisher: name: University of British Columbia
Year: 2011

description: This paper presents a model based on a synthesis of the four major themes in the standard literature on the rise of the protest movements on the prairies. The themes are a homogeneous population, a quasi-colonial economy, a non-partisan political system and the depression. They are given as explanations for the coming to power of the Progressive, Social Credit, and C.C.F. parties by the authors of this literature such as Morton, Sharp, Lipset, and Macpherson. An examination of the data relating to voter behaviour and population composition shows this model to be over-simplified. The imperfections of it are further highlighted by the historical data which indicate the different patterns of development of the western provinces. The political situation which arose in Canada after the 1917 election seems to give a much better indication of how the protest parties were able to achieve success on the prairies. In other words, both the total Canadian context and the individual provincial histories must be considered if one desires to understand the protest movement on the prairies.

description: The modern workspace is constantly evolving; what is in store for the future of how and where we work? Workspace creators need to provide a variety of activity landscapes intended for specific activities, and accessible to all. One size, one design, does not fit all! This thesis explores possibilities of connecting generations by transforming the traditional workspace to accommodate the ever-blurring boundaries between the workspace, hospitality spaces and the home spaces with the infusion of sophisticated modularity. Four generations contribute to today’s work environment including Baby Boomers, Generation X, Generation Y and Post Millennials. All of these generations have different expectations, values and motivations about their work environments. How can we become attuned to this emerging generation of workspace users, who often have very different ideas about how work should get done? Moreover, this thesis analyzes the integration and emphasis of work/life balance, workspace flexibility and user wellbeing, reinforced ideas generated through an open design processes, and explores how co-creation can facilitate the diffusion of innovation within an organization’s common workspaces known as lounge space. This thesis builds upon an existing product portfolio of office furniture by implementing human centered design through co-creation, and finding inspiration for innovation through heuristic methodologies in order to inform design decisions. With an emphasis on workspace ideologies and theories, exciting propositions based on design principles and workspace psychology, such as the incorporation of sophisticated modularity, lounge-as-office principles, prioritizing play, and supporting working happy, provide interesting insights into this research. This collection of artifacts provides functional and flexible characteristics while being attractive enough to be enjoyed outside of workspaces.

description: Coherent and reversible mapping of quantum information between light and matter is an important experimental challenge in quantum information science. In particular, it is a decisive milestone for the implementation of quantum networks and quantum repeaters. So far, quantum interfaces between light and atoms have been demonstrated with atomic gases, and with single trapped atoms in cavities. Here we demonstrate the coherent and reversible mapping of a light field with less than one photon per pulse onto an ensemble of 10 millions atoms naturally trapped in a solid. This is achieved by coherently absorbing the light field in a suitably prepared solid state atomic medium. The state of the light is mapped onto collective atomic excitations on an optical transition and stored for a pre-programmed time up of to 1 mu s before being released in a well defined spatio-temporal mode as a result of a collective interference. The coherence of the process is verified by performing an interference experiment with two stored weak pulses with a variable phase relation. Visibilities of more than 95% are obtained, which demonstrates the high coherence of the mapping process at the single photon level. In addition, we show experimentally that our interface allows one to store and retrieve light fields in multiple temporal modes. Our results represent the first observation of collective enhancement at the single photon level in a solid and open the way to multimode solid state quantum memories as a promising alternative to atomic gases.

description: We study the topological edge states of the Haldane's graphene model with zigzag/armchair lattice edges. The Harper equation for solving the energies of the edge states is derived. The results show that there are two edge states in the bulk energy gap, corresponding to the two zero points of the Bloch function on the complex-energy Riemann surface. The edge-state energy loops move around the hole of the Riemann surface in appropriate system parameter regimes. The quantized Hall conductance can be expressed by the winding numbers of the edge states, which reflects the topological feature of the Haldane model.

description: Foreword: This is the sixth in a series of lists on "Agricultural Relief Measures Relating to the Raising of farm Prices." The first three were compiled in October 1935 for the Seventieth, Seventy-first, and Seventy-second Congresses; the fourth in February 1939 (as Agricultural Economics Bibliography No. 76) for the Seventy-fifth Congress; and the fifth in April 1940 (as Agricultural Economics Bibliography No. 84) for the Seventy-fourth Congress. Bills proposing to raise prices generally through a change in the national monetary or banking system have, for the most part, been omitted, including the Thomas Inflation Amendment which is Title III of the Agricultural Adjustment Act, 1933 (Public No. 10, Approved May 12, 1933). Exceptions have been made in the case of the following bills: H.R. 3373 (item 98); H.R. 7320 (item 100); H.R. 7475 (item 101); H.R. 7581 (item 102); and S. 3039 (item 22). The bills in this list have been classified under the major agricultural relief plans which were considered in the Seventy-third Congress. Although it is recognized that some bills might he classified under more than one plan the titles have not been repeated. An effort has been made to bring out in the index the different plans in the separate bills. In addition to bills, references to Congressional hearings have been included. The numbers following the citations to the hearings, are call numbers used in the Library of the U.S. Department of Agriculture. An author and subject index and a numerical index to the Public Acts, bills and resolutions have been appended.

description: We study the nonrelativistic limit of the motion of a classical particle in a model of deformed special relativity and of the corresponding generalized Klein-Gordon and Dirac equations, and show that they reproduce nonrelativistic classical and quantum mechanics, respectively, although the rest mass of a particle no longer coincides with its inertial mass. This fact clarifies the meaning of the different definitions of velocity of a particle available in DSR literature. Moreover, the rest mass of particles and antiparticles differ, breaking the CPT invariance. This effect is close to observational limits and future experiments may give indications on its effective existence.

description: We study another realization of the Kerr/CFT correspondence. By imposing new asymptotic conditions for the near horizon geometry of Kerr black hole, an asymptotic symmetry which contains all of the exact isometries can be obtained. In particular, the Virasoro algebra can be realized as an enhancement of SL(2,R) symmetry of the AdS geometry. By using this asymptotic symmetry, we discuss finite temperature effects and show the correspondence concretely.

description: The relativistic shock layer problem was numerically analyzed by using two relativistic Boltzmann-kinetic equations. One is Marle model, and the other is Anderson-Witting model. As with Marle model, the temperature of the gain term was determined from its relation with the dynamic pressure in the framework of 14-moments theory. From numerical results of the relativistic shock layer problem, behaviors of projected moments in the nonequilibrium region were clarified. Profiles of the heat flux given by Marle model and Anderson-Witting model were quite adverse to the profile of the heat flux approximated by Navier-Stokes-Fourier law. On the other hand, profiles of the heat flux given by Marle model and Anderson-Witting model were similar to the profile approximated by Navier-Stokes-Fourier law. Additionally we discuss the differences between Anderson-Witting model and Marle model by focusing on the fact that the relaxational rate of the distribution function depends on both flow velocity and molecular velocity for Anderson-Witting model, while it depends only on the molecular velocity for Marle model.

description: Radiation from GRBs in the prompt phase, flares and an afterglow is thought to be produced by accelerated electrons in magnetic fields. Such emission may be produced at collisionless shocks of baryonic outflows or at reconnection sites (at least for the prompt and flares) of the magnetically dominated (Poynting flux driven) outflows, where no shocks presumably form at all. An astonishing recent discovery is that during reconnection strong small-scale magnetic fields are produced via the Weibel instability, very much like they are produced at relativistic shocks. The relevant physics has been successfully and extensively studied with the PIC simulations in 2D and, to some extent, in 3D for the past few years. We discuss how these simulations predict the existence of MeV-range synchrotron/jitter emission in some GRBs, which can be observed with Fermi. Recent results on modeling of the spectral variability and spectral correlations of the GRB prompt emission in the Weibel-jitter paradigm applicable to both baryonic and magnetic-dominated outflows is reviewed with the emphasis on observational predictions.

description: The chemical composition of essential oils (EO) from bark and leaf of P. zhennan was identified by GC-MS. The compounds of α-calacorene, τ-cadinol, β-eudesmol and d-cadinene were found in the essential oils from both bark and leaf. The UV-Vis spectra results indicated the EO could completely absorbed the UV light at the wavelength range of 200-370 nm, revealing that EO had great potential as additives for manufacturing UV light blocking products. The radical DPPH scavenging activity assay showed that both the bark and leaf EO possessed strong DPPH radical scavenging activity of 90.25% and 82.10% respectively, which provides an important theoretical guiding in exploiting the value of P. zhennan bark and leaf.

Stress (psychology)

description: Today, more than-one quarter of the workforce population in Canada feels stressed (Government of Canada, 2015; Mental Health Commission of Canada [MHCC], 2015, p. 39), and work is one of the main sources of stress (Crompton, 2011, p. 46). Being self-aware, and conscious of the sources of our own stress are key for changing how we deal with everyday stressors. The body of design research presented in this thesis resulted in a design framework for creating mindful reflection practices regarding how we perceive, express and contemplate our life experiences. Through participatory design, individuals who feel stressed were engaged in co-creation and journaling activities in order to generate insights on: 1) how they were feeling during the day from an emotional, mental, physical and social perspective; 2) the possible reasons for such feelings; 3) the actions they took or envisioned taking in order to de-stress during that day. In a practice-led investigation, the ring patterns seen on the cross-section of a tree log were the inspiration for the design of visual and physical artefacts. These rings carry a lifetime of experiential information, suggesting that the way we choose to live our everyday experiences directly contribute to the person we become.

Towards understanding the approximation of Boolean functions by nonclassical polynomials
Creators: name: Bhrushundi, Abhishek
Publisher: name: No Publisher Supplied

description: The representation and approximation of Boolean functions by polynomials is an important area of research in theoretical computer science, having numerous applications in circuit complexity, communication complexity, pseudorandomness, quantum computation, learning theory, algorithm design, and explicit combinatorial constructions.Results of Green and Tao (2009), Lovett et al. (2011), and Tao and Ziegler (2012), on the Inverse Conjecture for the Gowers norm over finite fields of low characteristic, and the subsequent work of Bhowmick and Lovett (2015), suggest that a potential barrier to the resolution of some of the outstanding open problems in this area is the class of nonclassical polynomials and its ability to nontrivially represent and approximate Boolean functions.Motivated by these works, in this dissertation, we investigate the ability of nonclassical polynomials to approximate Boolean functions with respect to both previously studied and new notions of approximation:• We introduce and study an agreement-based notion of approximation by polynomials over Z/2k Z. Investigating this notion serves as a proxy for understanding the maximum possible agreement between nonclassical polynomials and Boolean functions. We prove several new results that shed light on this new notion of approximation, and these results help us answer some questions left open in thework of Bhowmick and Lovett (2015) concerning the approximation of Booleanfunctions by nonclassical polynomials in the agreement sense.• We propose a new notion of point-wise approximation by nonclassical polynomials. Using a result of Green et al. (1992), which itself is an extension of the classic work of Beigel and Tarui (1991), we observe that Boolean functions computable by ACC0 circuits (constant-depth circuits of polynomial size, containing AND, OR, NOT, and MODq gates) are amenable to point-wise approximation by low-degree nonclassical polynomials. Motivated by this new observation, we then explore how well can low-degree nonclassical polynomials point-wise approximate the majority function, in the hope of resolving the longstanding open problem of proving that majority is not computable by ACC0 circuits.Our results suggest several interesting and promising directions of research. We ex-plore some of these directions and state concrete open problems along with plausibleapproaches to solving them.

description: In this paper, we derive the explicit series expansion of the eigenvalue distribution of various models, namely the case of non-central Wishart distributions, as well as correlated zero mean Wishart distributions. The tools used extend those of the free probability framework, which have been quite successful for high dimensional statistical inference (when the size of the matrices tends to infinity), also known as free deconvolution. This contribution focuses on the finite Gaussian case and proposes algorithmic methods to compute the moments. Cases where asymptotic results fail to apply are also discussed.

description: We will construct differential forms on the embedding spaces Emb(R^j,R^n) for n-j>=2 using configuration space integral associated with 1-loop graphs, and show that some linear combinations of these forms are closed in some dimensions. There are other dimensions in which we can show the closedness if we replace Emb(R^j,R^n) by fEmb(R^j,R^n), the homotopy fiber of the inclusion Emb(R^j,R^n) -> Imm(R^j,R^n). We also show that the closed forms obtained give rise to nontrivial cohomology classes, evaluating them on some cycles of Emb(R^j,R^n) and fEmb(R^j,R^n). In particular we obtain nontrivial cohomology classes (for example, in H^3(Emb(R^2,R^5))) of higher degrees than those of the first nonvanishing homotopy groups.
