description: COMMUNE (Co-production of Mental Health Nursing Education) is an Erasmus+ Strategic Partnership Project based on the collaboration of experts by experience (EBE) and mental health nursing academics from six European universities and the University of Canberra in Australia. Its purpose was to advance the involvement of those who have experiences of mental health service use (EBE) in mental health nursing education. The project combined experiential and academic knowledge, with the aim of co-producing a module on ‘mental health recovery’ for undergraduate nursing students; a module that was taught to the students by EBE. Principles of co-production where followed as much as possible, involving EBE in all stages of the process, from grant application to dissemination. The project tried to move beyond typical service user involvement and towards co-creation of knowledge, where power differentials are acknowledged and equity issues addressed. Barriers to meeting these goals were experienced and will be discussed in this Guidelines. We hope that these Practice Guidelines will be useful for those who intend to co-produce learning programs or modules in mental health nursing and inspire others to follow similar paths and learn from our experiences, positive or otherwise. These Guidelines provide an overview of our experiences, learnings, limitations and barriers.The Commune team decided on the term ‘Expert by Experience’ (EBE) to describe the members of the team and other collaborators who has lived experience of mental distress. Other more commonly used terms are ‘service user’, ‘consumer’ and ‘people with mental illness.’ As not all experts by experience are mental health care users, and what constitutes an illness is highly debated, the team decided on a term that more correctly describes and value lived experience.
The Desire for Whiteness: Can Law and Economics Explain it?
Creators: name: Bhattacharya, Shilpi
Publisher: name: Columbia Journal of Race and Law
Year: 2012

description: This Essay provides a new theoretical perspective on colorism by considering it from an economic point of view. It relies on three theories of law and economics that explain racism. While critiquing these theories, it also extends them to evaluate colorism. Because these theories correlate race with skin color, applying these theories to colorism requires distinguishing colorism from racism using the “desire for whiteness” as a tool for analysis. Further, this Article provides a comparative perspective of colorism in the traditional American labor market and the Indian arranged marriage “market.” It finds that: (a) these theories are able to provide some insight into why decisions in these markets are colorist; (b) the insights are incomplete and do not fully explain the complexities of colorist interactions, though they do explain some of colorism’s history; (c) the Indian arranged marriage market strengthens these theories; and (d) only McAdams’s status production theory is able to deliver an account of the desire for whiteness. It concludes that a legal framework relating to colorism should aim to eliminate this desire from society.

description: We study the boundary states of the archetypal three-dimensional topological order, i.e. the three-dimensional $\mathbb{Z}_2$ toric code. There are three distinct elementary types of boundary states that we will consider in this work. In the phase diagram that includes the three elementary boundaries there may exist a multi-critical point, which is captured by the so-called deconfined quantum critical point (DQCP) with an "easy-axis" anisotropy. Moreover, there is an emergent $\mathbb{Z}_{2,\text{d}}$ symmetry that swaps two of the boundary types, and it becomes part of the global symmetry of the DQCP. The emergent $\mathbb{Z}_{2,\text{d}}$ symmetry on the boundary is originated from a type of surface defect in the bulk. We further find a gapped boundary with a surface topological order that is invariant under the emergent symmetry.

description: The discrete-time, the quantum, and the continuous calculus of variations have been recently unified and extended. Two approaches are followed in the literature: one dealing with minimization of delta integrals; the other dealing with minimization of nabla integrals. Here we propose a more general approach to the calculus of variations on time scales that allows to obtain both delta and nabla results as particular cases.

Anthocyanin accumulation and cuticular wax deposition in blueberries : Impacts on fruit surface color and water loss
Creators: name: Yan, Yifan
Publisher: name: University of British Columbia
Year: 2024

description: Blueberry (Vaccinium spp.) is an important horticultural crop with high economic and nutritional values. Anthocyanins are the pigments determining fruit surface color, one of the most important quality traits affecting consumers’ choices; cuticular waxes are the major components of the cuticle affecting fruit water loss and determining fruit shelf-life. In this thesis, time-course changes of anthocyanins and cuticular waxes were characterized during blueberry ripening and storage; the effects of these changes on fruit surface color and water loss were determined; the candidate genes underlying cuticular wax deposition were identified in blueberries by transcriptome analysis. Different types of glycosylated anthocyanins were detected, and variations in their relative abundances determined distinct anthocyanin profiles among genotypes. Variations in anthocyanin concentrations and profiles did not correlate to variations in fruit surface color among genotypes. Cuticular waxes affected fruit surface color, and a higher content of beta-diketones – the second largest group of wax compounds in blueberries – determined a lighter fruit surface. The majority of blueberry water loss occurred through fruit cuticle; however, the contribution of cuticle versus stem scar varied among genotypes. The profile of triterpenoids – the most abundant group of wax compounds – played a critical role in determining fruit water loss, and a higher ratio of oleanolic acid to ursolic acid was associated with a lower water loss. The total wax content (micrograms cm–2) decreased during ripening, mainly due to fruit expansion. The total wax load (micrograms berry–1) increased during storage, suggesting de novo synthesis and deposition of cuticular waxes. Transcriptome analysis revealed putative genes related to biosynthesis of triterpenoids in blueberries. Five putative oxidosqualene cyclases (OSC-Like1–5) catalyze the production of various triterpene alcohols (e.g., alpha-amyrin, beta-amyrin, and lupeol), the rate limiting step in triterpenoid production. Three putative CYP716A subfamily monooxygenases (CYP716A-Like1–3) underlay the production of triterpene acids (e.g., oleanolic acid and ursolic acid). This study provides novel insights on the roles of anthocyanins and cuticular waxes in determining fruit surface color and water loss in blueberries during fruit ripening and postharvest storage. These insights will allow blueberry breeding programs to develop new varieties with improved color and shelf-life.
From lattice BF gauge theory to area-angle Regge calculus

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We consider Riemannian 4d BF lattice gauge theory, on a triangulation of spacetime. Introducing the simplicity constraints which turn BF theory into simplicial gravity, some geometric quantities of Regge calculus, areas, and 3d and 4d dihedral angles, are identified. The parallel transport conditions are taken care of to ensure a consistent gluing of simplices. We show that these gluing relations, together with the simplicity constraints, contain the constraints of area-angle Regge calculus in a simple way, via the group structure of the underlying BF gauge theory. This provides a precise road from constrained BF theory to area-angle Regge calculus. Doing so, a framework combining variables of lattice BF theory and Regge calculus is built. The action takes a form {\it à la Regge} and includes the contribution of the Immirzi parameter. In the absence of simplicity constraints, the standard spin foam model for BF theory is recovered. Insertions of local observables are investigated, leading to Casimir insertions for areas and 6j-symbols for 3d angles. The present formulation is argued to be suitable for deriving spin foam models from discrete path integrals.

Orbital Hall physics in two-dimensional Dirac materials

description: Orbitronics has recently emerged as a very active research topic after several proposals aiming to exploit the orbital degree of freedom for charge-free electronics. In this communication, we investigate orbital transport in selected two-dimensional systems to better understand which parameters govern the intra-atomic and inter-atomic contributions to the orbital Hall effect. We study the impact of the gap, the role of the materials' topology and the influence of the disorder on spin and orbital Hall transport. Starting from the Kane-Mele model, we describe how the orbital moment behaves depending on the material's topology and clarify the influence of the gap on the orbital Hall conductivity. We then extend the study to realistic topologically trivial and non-trivial materials, and find that the topology has little qualitative influence on the orbital Hall conductivity. In contrast, we observe that the energy dispersion has a more dramatic impact, especially in the presence of disorder. Remarkably, our results suggest that the intra-atomic orbital Hall current is more robust against scattering than the inter-atomic one, without further impact of the topological properties of the system under consideration.
Forward: When the Stars Begin to Fall: Introduction to Critical Race Theory and Marxism

Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: Marxism, they say, is dead. But the classless society is nowhere in sight. Racism is also dead, or so they tell us. But the colorline is still wrapped tightly around the world. The reports of these deaths are connected and premature. They are connected to the destruction of words. They are premature in the way declarations of final victory are always premature. If we credit Louis Althusser’s observation that “philosophy represents the people’s class struggle in theory,” then our engagement with these attempted dispossessions is a serious matter. This project will show the vitality of Marxism by locating it within what Critical Race Theory should become.

Critical Race Theory & Marxism: Temporal Power
Creators: name: Farley, Anthony Paul
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: This Essay on modern progress spins out of Marxism a theory of time about which Marxism itself has remained largely unconscious. Marxism is a theory of the already-taken. Critical Race Theory has as its animating spirit, its haunt, a related—but up until now only latent—temporal theory of the already-taken. The unconscious, we learn from psychoanalysis, does not know time; it is timeless. The authority of law comes to us from this same time out of mind. The four corners of this Essay’s theory of the already-taken are Marxism, Critical Race Theory, psychoanalysis, and jurisprudence. The already-taken is the unconscious of law.

W. E. B. Du Bois’ Ambiguous Politics of Liberation: Race, Marxism and Pan Africanism
Creators: name: Geary, Adam
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: W. E. B. Du Bois summons the restless and provocative spirit of a Pan Africanism that, despite its association with the collapse of Kwamah Nkumah’s Ghanaian revolution, has not failed as an idea. Commentators have realised, to some extent, the ambiguities of Du Bois’ Pan Africanism. However, they have not shown how Du Bois’ deployment of the concept opens up a more radical political thinking. This Essay will trace the various twists and turns of Du Bois’ Pan Africanism as narrated in the text Dusk of Dawn. Pan Africanism demands a social, economic, and political revolution that goes beyond the civil liberties struggle and its focus on constitutional recognition. In leaving America for Ghana, Du Bois committed himself to a very specific understanding of the African revolution. Using the ideas of Etienne Balibar and Jacques Rancière, this Essay will argue that Du Bois’ Pan Africanism evoked energies of revolution that point at an unfinished, rather than failed, radical project.

description: [Abridged] We present new VLT ISAAC spectra for 30 quasars, which we combine with previous data to yield a sample of 53 intermediate redshift (z ~ 0.9 - 3.0) sources. The sample is used to explore properties of prominent lines in the Hbeta spectral region of these very luminous quasars. We find two major trends: (1) a systematic increase of minimum FWHM Hbeta with luminosity (discussed in a previous paper). This lower FWHM envelope is best fit assuming that the narrowest sources radiate near the Eddington limit, show line emission from a virialized cloud distribution, and obey a well defined broad line region size vs. luminosity relation. (2) A systematic decrease of equivalent width of [OIII] (from W ~ 15 to ~ 1 A) with increasing source bolometric luminosity (from log L ~ 43 to log L ~ 49). Further identified trends required discrimination between so-called Population A and B sources. We generate median composite spectra in six luminosity bins Pop. A sources show reasonably symmetric Lorentzian Hbeta profiles at all luminosities while Pop. B sources require two component fits involving an unshifted broad and a redshifted very broad component. Very broad Hbeta increases in strength with increasing L while the broad component remains constant resulting in an apparent "Baldwin effect" with equivalent width decreasing from W ~ 80 to ~ 20 A over our sample luminosity range. The roughly constant equivalent width shown by the Hbeta very broad component implies production in optically-thick, photoionized gas. The onset of the redshifted very broad component appears to be a critical change that occurs near the Pop. A-B boundary at FWHM Hbeta ~ 4000 km/s which we relate to a critical Eddington ratio (~ 0.2 +/- 0.1).

Electron-phonon coupling in insulators : beyond the Migdal limit
Creators: name: Fomichev, Stepan Olegovich
Publisher: name: University of British Columbia
Year: 2023

description: Motivated by the success of the momentum average (MA) approximation for the single-polaron and bipolaron cases, in this dissertation we pursue the first generalization of this technique to the case of weakly-doped insulators beyond the Migdal limit. In search of a suitable starting point, we investigate the ground states of a variety of model Hamiltonians, inspired by real materials such as rare-earth nickelates, polyacetylene, barium bismuthates, and buckminsterfullerene. Our study of the ground state of the 2D rare-earth nickelate sheet shows that it exhibits cuprate-like orbital polarization unimpeded by weak to moderate electron-phonon coupling. This lends further support to the proposal for cuprate-like superconductivity in nickelate thin films and heterostructures. Investigating polyacetylene leads us to develop a semi-analytical technique that can be used to account for zero-point lattice energy in determining the equilibrium geometry of any crystal. The study of a simplified, one-dimensional model of buckminsterfullerene results in the first generalization of MA to a system with two polaron clouds, and a phonon-driven mechanism for exciton dissociation that could be responsible for photocurrent generation in these materials. Because both the nickelates and polyacetylene turn out to be too complex as starting points for MA generalization, we focus on a simplified, s-p chain model of the barium bismuthates. We ultimately succeed in generalizing MA for this band insulator – the first application of its kind. We compare the results to those from determinant quantum Monte Carlo to establish the accuracy of the MA results (with the MA results obtained at lower computational cost). Finally, we share in the development of the first open-sourced Python package implementing automatic MA equation generation via the GGCE method, which allows MA-style methods to be easily used by non-experts – and is expected to expand in the coming years, providing access to many more MA-style methods in the future.
Beyond Supreme Court Anti-Discrimination: An Essay on Racial Subordinations, Racial Pleasures and Commodified Race
Creators: name: Gotanda, Neil
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: In recent years, the Supreme Court has narrowed its examination of racial subordinations to focus upon three doctrinal approaches: disparate treatment racial discrimination, the intent theory of racial discrimination, and suspect category strict scrutiny. Taken together, these three doctrines mutually reinforce racial discrimination as the only available legal understanding of racial subordination. Faced with the Court’s ever contracting list of issues available for discussion, some scholars have chosen to investigate outside the Court’s constricted understanding of race. This Essay begins by noting that racial subordinations—social subordinations premised on a schema of body types—are multiple and not limited to a single, narrow understanding. After introducing the Supreme Court’s restrictive approach in Section I, I examine in Section II recent scholarship on racial subordination that has pressed beyond the doctrinal confines created by the Supreme Court. I review authors discussing Title VII, common law contract, racial tropes, implicit bias, patent law, and trademark. Section III examines Professor Anthony Farley’s concept of racial pleasure—the idea that racial subordination gives pleasure to its participants. Racial pleasure is a form of racial subordination that falls outside of the Supreme Court’s understanding of racial subordination as racial discrimination. Through the examination of race in computer games, I suggest two distinctions. I observe a legal distinction between racial pleasures and commodified racial pleasures, and a normative legal distinction between permitted racial pleasures and illicit racial pleasures. Section III ends with a proposed standard for constitutional review of state regulation of illicit racial pleasures. As another interpretation of racial subordination, Section IV proposes a theorization of commodified race through Marx’ theory of commodity circulation. No PDF for this article is available.

Citizenship as Accumulated Racial Capital
Creators: name: Halewood, Peter
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: Despite persistent racial and economic inequality, many believe the United States is becoming a post-racial and classless society where race and class analysis are anachronisms. This Essay will contest that claim by way of a critical reading of citizenship as reflected in American law and culture and demonstrate the continuing relevance of race theory and Marxian analysis, notwithstanding their somewhat uneasy relationship. It examines how law and culture construct and reflect, on the one hand, xenophobic and racist popular images of aliens—particularly refugees and undocumented aliens—and, on the other hand, enable and assure the accumulation of racial capital and value in the notion of deserving, legitimate, and racialized (white) citizenship.

Compassion and Critique
Creators: name: Harris, Angela P.
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: In this Essay, I am interested in the relationship among ideology, ideological critique, and emotion. I argue that the ideological critique produced by Marx in the nineteenth century and by critical legal theorists in the twentieth and twenty-first centuries undertakes not only to persuade our minds but also to rally our emotions. To accomplish this, critical theorists show us that ideology is already a technique of emotion management. Ideology makes suffering invisible and compassion inappropriate by assuring us that the status quo is natural, normal, and necessary. Ideological critique, in turn, reveals the suffering beneath the bland façade of ideological concepts like “capital” and “property.” It tries to persuade us, moreover, that this suffering is unjust and unnecessary: that politics and not nature is its source, and that we should act to relieve it.

The Perverse Logic of Immigration Detention: Unraveling the Rationality of Imprisoning Immigrants Based on Markers of Race and Class Otherness
Creators: name: Hernández, César Cuauhtémoc García
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: In an effort to explain the massive growth of immigration imprisonment, this Essay explores the use of race and class as tools for policing immigration law. The Essay does this by contemplating the effect of an immigration law scheme that, at its most fundamental, requires sorting desirable immigrants from undesirable immigrants, and that, in recent years, has accomplished this sorting through increased reliance on criminal records. Placing these two features of contemporary immigration law within the context of two decades-old forms of indisputably racialized policing—mass incarceration of black and brown people for criminal law violations and the Supreme Court’s sanctioning of racial profiling in immigration law policing—the Essay concludes that it was inevitable for penal imprisonment trends to taint immigration law enforcement with raced and classed mass incarceration.

description: Improving object manipulation skills through hand-object interaction exercises is crucial for rehabilitation. Despite limited healthcare resources, physical therapists propose remote exercise routines followed up by remote monitoring. However, remote motor skills assessment remains challenging due to the lack of effective motion visualizations. Therefore, exploring innovative ways of visualization is crucial, and virtual reality (VR) has shown the potential to address this limitation. However, it is unclear how VR visualization can represent understandable hand-object interactions. To address this gap, in this paper, we present VRMoVi, a VR visualization system that incorporates multiple levels of 3D visualization layers to depict movements. In a 2-stage study, we showed VRMoVi's potential in representing hand-object interactions, with its visualization outperforming traditional representations, and detailed features improved the hand-object interactions understanding. This study takes the initial step in developing VR visualization of hand-object interaction to support remote physical therapy.

High energy constraints in the octet SS-PP correlator and resonance saturation at NLO in 1/Nc

description: We study the octet SS-PP correlator within resonance chiral theory up to the one-loop level, i.e., up to next-to-leading order in the 1/Nc expansion. We will require that our correlator follows the power behaviour prescribed by the operator product expansion at high euclidian momentum. Nevertheless, we will not make use of short-distance constraints from other observables. Likewise, the high-energy behaviour will be demanded for the whole correlator, not for individual absorptive channels. The amplitude is progressively improved by considering more and more complicated operators in the hadronic lagrangian. Matching the resonance chiral theory result with chiral perturbation theory at low energies produces the estimates L_8(mu)^{SU(3)} = (1.0+-0.4)10^-3 and C_{38}(mu)^{SU(3)} = (8+-5) 10^-6 for mu=770 MeV. The effect of alternative renormalization schemes is also discussed in the article.

description: We investigate the magnetic properties of three Mn$_6$ single molecule magnets by means of inelastic neutron scattering and frequency domain magnetic resonance spectroscopy. The experimental data reveal that small structural distortions of the molecular geometry produce a significant effect on the energy level diagram and therefore on the magnetic properties of the molecule. We show that the giant spin model completely fails to describe the spin level structure of the ground spin multiplets. We analyze theoretically the spin Hamiltonian for the low spin Mn$_6$ molecule (S=4) and we show that the excited $S$ multiplets play a key role in determining the effective energy barrier for the magnetization reversal, in analogy to what was previously found for the two high spin Mn6 (S=12) molecules [S. Carretta et al., Phys. Rev. Lett. 100, 157203 (2008)].

Global Class and the Commercial-Sexual Exploitation of Children: Toward A Multidimensional Understanding
Creators: name: Javidan, Pantea
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: This Essay draws together several focal points of the Third Annual National People of Color Conference in 2010, human trafficking, racial contexts, criminal law, immigration law and international law, while addressing the core theme of post-racialism and other “posts.” The purpose of this Essay is three-fold. First, it challenges the notion that we live in a post-race, post-class, or post-feminist environment in which race, class and gender disparities in contemporary law and society have diminished or are diminishing to a point at which discussing inequalities along these lines is unavailing. Second, using a Multidimensional approach that includes childhood and age as significant dimensions of inequality, this Essay develops a concept of class to enhance Critical Class Theory (“Class Crits”). Third, it challenges “the posts” through a social problem that epitomizes “multidimensional subordination”—child sex trafficking—with particular focus on the commercial sexual exploitation of children through prostitution in the United States.

Identification of Optimal Topography by Variational Data Assimilation
Creators: name: Kazantsev, Eugene

description: The use of data assimilation technique to identify optimal topography is discussed in frames of time-dependent motion governed by non-linear barotropic ocean model. Assimilation of artificially generated data allows to measure the influence of various error sources and to classify the impact of noise that is present in observational data and model parameters. The choice of assimilation window is discussed. Assimilating noisy data with longer windows provides higher accuracy of identified topography. The topography identified once by data assimilation can be successfully used for other model runs that start from other initial conditions and are situated in other parts of the model's attractor.

description: Hadron electromagnetic form factor in the time-like region at the boundary of the physical region is considered. The energy behavior of the form factor is shown to be determined by the strong hadron-antihadron interaction. Imaginary parts of the scattering lengths for $p\bar{p}$, $Λ\barΛ$, $Λ\barΣ^0 (\barΛΣ^0)$ and $Σ^0\barΣ^0$ are estimated. Developed approach enables us to estimate imaginary part of the scattering volume from $D^*\bar{D^*}$ experimental data. The form factor energy behavior away from the threshold is obtained within a semiphenomenological model of hadron-antihadron interaction.

description: We study the kinematics of stars both at their formation and today within 14 Milky Way (MW)-mass galaxies from the FIRE-2 cosmological zoom-in simulations. We quantify the relative importance of cosmological disk settling and post-formation dynamical heating. We identify three eras: a Pre-Disk Era (typically >8 Gyr ago), when stars formed on dispersion-dominated orbits; an Early-Disk Era (~ 8 - 4 Gyr ago), when stars started to form on rotation-dominated orbits but with high velocity dispersion, sigma_form; and a Late-Disk Era (< 4 Gyr ago), when stars formed with low sigma_form. sigma_form increased with time during the Pre-Disk Era, peaking ~ 8 Gyr ago, then decreased throughout the Early-Disk Era as the disk settled and remained low throughout the Late-Disk Era. By contrast, the velocity dispersion measured today, sigma_now, increases monotonically with age because of stronger post-formation heating for Pre-Disk stars. Importantly, most of sigma_now was in place at formation, not added post-formation, for stars younger than ~ 10 Gyr. We compare the evolution of the three velocity components: at all times, sigma_R,form > sigma_phi,form > sigma_Z,form. Post-formation heating primarily increased sigma_R at ages < 4 Gyr but acted nearly isotropically for older stars. The kinematics of young stars in FIRE-2 broadly agree with the range observed across the MW, M31, M33, and PHANGS-MUSE galaxies. The lookback time that the disk began to settle correlates with its dynamical state today: earlier-settling galaxies currently form colder disks. Including stellar cosmic-ray feedback does not significantly change disk rotational support at fixed stellar mass.

The Legal Politics of Hubert H. Harrison: Excavating a Lost Legacy
Creators: name: Malhotra, Ravi
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: Critical race theorists (CRT) have cogently argued the need for anti-racist struggles in the post-civil rights era to address the fact that integration has hardly resolved the continued marginalization and discrimination of African Americans in housing, employment, and many other dimensions and to reflect on how law facilitates racial subordination in the post-civil rights era. However, this Essay suggests that these arguments can be better understood and enriched by a deep appreciation of the breathtaking legacy of Hubert Henry Harrison (1883-1927) and a close reading of his works. As a working class activist and intellectual in both the Socialist Party and the Industrial Workers of the World (IWW), Harrison was later a major influence in Marcus Garvey’s nationalist movement and the New Negro Movement, editor of The Voice and The Negro World, and the founder of the Liberty League. Largely lost to history, Harrison’s astonishing body of work on racism and the political issues of his time force us to rethink a period of African American history that typically has been regarded as a low point in the struggle against racism and white supremacy. Yet in fact, Harrison found answers to the questions that would haunt advocates of racial equality for years to come.

Contract and Dispossession
Creators: name: Post, Deborah
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: In the not so distant past, law students often opened their Contracts casebooks to find a quotation from Sir Henry Maine, “The movement of progressive societies has hitherto been a movement from Status to Contract.” The placement of this quotation at the beginning of a Contracts book sets the tone for the semester or the year, providing a theme that the law professor either embraced or critiqued: the idea that contract is liberatory. This Essay, part of a collection of essays on the same theme, argues that contract law has become an instrument of oppression and dispossession rather than liberation. Having offered a critique, the challenge then is to consider whether it is possible to restore the liberatory potential of contract. The symposium, Post-Marxism, Post-Racialism and Other Fables of the Dispossession, was an invitation to consider the contemporary relevance of Marxist theory. The aspect of Marxist theory referenced in this particular essay is cultural and ethnographic, a methodology suggested by Robert Sullivan’s argument that Marx was anthropological in his epistemology and in his form of argument. Sullivan also argues that the theoretical approach advocated by some anthropologists, a “cultural critique of ourselves,” is Marxist because it is the “modern analogue to Marx’s earlier use of primitive society as both a critique of nineteenth century capitalist economy and as an alternative way of ‘seeing’ reality.” Modern Ethnography, he concludes, “produces its critique . . . by demystifying and denaturalizing cultural texts and ‘reading’ their social meaning.”

“Precious”: A Tale of Three Explanations for Childhood Maltreatment
Creators: name: Robinson, Reginald Leamon
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: Precious describes a fictional child’s life, in which the parents severely maltreat her. Historically, society gave parents the right to assault their children’s bodies, if those assaults were not abuse but discipline. Traditionally, constitutional analysis enshrined those rights, and parents had autonomy to rear and discipline their children as they saw fit. Unfortunately, when parents abused their children and were prosecuted, few exculpatory and justificatory explanations were offered. Today, we know that parents who abuse have suffered abuse, too. Hence, Precious’ parents’ childhood histories help to explain her maltreatment and reveal the best framework for the etiology of her horrific suffering. This Essay proffers three explanations: Critical Race Theory’s (CRT) race consciousness, Karl Marx’ alienation theory, and Alice Miller’s psycho-existential framework. Each approach may explain why parents maltreat their children. In brief, CRT and alienation theories operate at structural levels, well above the intergenerational transfer of actual suffering from parent to child. To be sure, structuralist theories may explain why black children like Precious suffered horrific maltreatment not by faulting the parents but by pointing to external, objective forces like white racism. CRT begins by analyzing slavery, Jim Crow, and the breakdown of the black family. Marxism likewise starts by critiquing an economic world in which capitalism’s slavery exploited workers and black slaves. Yet, violent, physical assaults against children predate American Negro slavery and modern capitalism, which mean that neither of them would completely and persuasively explain childhood maltreatment. And neither approach takes us beyond believing that external, objective forces have constructed our abusive imaginations, which are enforced by the hegemonic workings of powerful whites and white structural oppression.

Why Obama is Black: Language, Law and Structures of Power
Creators: name: ., SpearIT
Publisher: name: Columbia Journal of Race and Law
Year: 2011

description: When he filled out the race section of the 2010 U.S. Census survey, President Barack Obama checked the “Black, African Am., or Negro” box despite the fact that Obama is of both European-American and African ancestry. This simple fact raises a number of complicated questions and challenges the idea that race, or more properly, racism, is a thing of the past or “post” as used in “post-racial.” What follows is a critique of the “post-racial” ideology. Centuries of racial sedimentation have made some aspects of racism invisible to the eye, yet an analysis of the post-racial concept shows that debates on race and color are fundamentally flawed. This Essay exposes the concept as a type of wishful thinking, and more critically, how the law prevents this wish from being fulfilled. No PDF is available for this Article.
