Are Racial and Ethnic Minorities Less Willing to Participate in Health Research?
David Wendler ,Raynard Kington,Jennifer Madans,Gretchen Van Wye,Heidi Christ-Schmidt,Laura A Pratt,Otis W Brawley,Cary P Gross,Ezekiel Emanuel
PLOS Medicine , 2006, DOI: 10.1371/journal.pmed.0030019
Abstract: Background It is widely claimed that racial and ethnic minorities, especially in the US, are less willing than non-minority individuals to participate in health research. Yet, there is a paucity of empirical data to substantiate this claim. Methods and Findings We performed a comprehensive literature search to identify all published health research studies that report consent rates by race or ethnicity. We found 20 health research studies that reported consent rates by race or ethnicity. These 20 studies reported the enrollment decisions of over 70,000 individuals for a broad range of research, from interviews to drug treatment to surgical trials. Eighteen of the twenty studies were single-site studies conducted exclusively in the US or multi-site studies where the majority of sites (i.e., at least 2/3) were in the US. Of the remaining two studies, the Concorde study was conducted at 74 sites in the United Kingdom, Ireland, and France, while the Delta study was conducted at 152 sites in Europe and 23 sites in Australia and New Zealand. For the three interview or non-intervention studies, African-Americans had a nonsignificantly lower overall consent rate than non-Hispanic whites (82.2% versus 83.5%; odds ratio [OR] = 0.92; 95% confidence interval [CI] 0.84–1.02). For these same three studies, Hispanics had a nonsignificantly higher overall consent rate than non-Hispanic whites (86.1% versus 83.5%; OR = 1.37; 95% CI 0.94–1.98). For the ten clinical intervention studies, African-Americans' overall consent rate was nonsignificantly higher than that of non-Hispanic whites (45.3% versus 41.8%; OR = 1.06; 95% CI 0.78–1.45). For these same ten studies, Hispanics had a statistically significant higher overall consent rate than non-Hispanic whites (55.9% versus 41.8%; OR = 1.33; 95% CI 1.08–1.65). For the seven surgery trials, which report all minority groups together, minorities as a group had a nonsignificantly higher overall consent rate than non-Hispanic whites (65.8% versus 47.8%; OR = 1.26; 95% CI 0.89–1.77). Given the preponderance of US sites, the vast majority of these individuals from minority groups were African-Americans or Hispanics from the US. Conclusions We found very small differences in the willingness of minorities, most of whom were African-Americans and Hispanics in the US, to participate in health research compared to non-Hispanic whites. These findings, based on the research enrollment decisions of over 70,000 individuals, the vast majority from the US, suggest that racial and ethnic minorities in the US are as willing as non-Hispanic
Homeless in Galilee
RL Brawley
HTS Theological Studies/Teologiese Studies , 2011,
Abstract: This article has located Jesus’ saying about homelessness in the context of the Roman Empire as it was experienced in Galilee. Homelessness is part of a broader picture that translates into loss of access to the resources of the land. The thesis is that in light of a theology of land resulting from the development of Abrahamic covenant traditions and the prophetic hope expressed especially in Isaiah, Ezekiel and Psalm 37, Jesus proclaimed God’s kingdom as God’s rule over heaven and earth, which implicates restoration of equitable access to the resources of the earth. The Lord’s Prayer, presumptions about the water of Jacob’s well in John 4 and the parable of the unjust steward in Luke 16 are used to demonstrate understandings of violations of equitable

Non-linear optomechanical measurement of mechanical motion
G. A. Brawley,M. R. Vanner,P. E. Larsen,S. Schmid,A. Boisen,W. P. Bowen
Physics , 2014,
Abstract: Precision measurement of non-linear observables is an important goal in all facets of quantum optics. This allows measurement-based non-classical state preparation, which has been applied to great success in various physical systems, and provides a route for quantum information processing with otherwise linear interactions. In cavity optomechanics much progress has been made using linear interactions and measurement, but observation of non-linear mechanical degrees-of-freedom remains outstanding. Here we report the observation of displacement-squared thermal motion of a micro-mechanical resonator by exploiting the intrinsic non-linearity of the radiation pressure interaction. Using this measurement we generate bimodal mechanical states of motion with separations and feature sizes well below 100~pm. Future improvements to this approach will allow the preparation of quantum superposition states, which can be used to experimentally explore collapse models of the wavefunction and the potential for mechanical-resonator-based quantum information and metrology applications.

Evocative allusions in Matthew: Matthew 5:5 as a test case
Robert L. Brawley
HTS Theological Studies/Teologiese Studies , 2009, DOI: 10.4102/hts.v59i3.666
Abstract: Combining theories of intertextuality and abductive reasoning, this article demonstrates the figurative nature of scriptural allusions in Matthew. Allusions form figurations that open new perspectives for readers inasmuch as the source text and the new text stand in a tensive relationship in which each modifies the other and in which together they evoke meaning beyond the mere sum of the two independent texts. Allusions also form figurations inasmuch as arguments that are analogous to logic. Surprising, original, uncanny correlations between the source text and the new text involve what Charles Peirce called abductive reasoning which also challenges constructs of reality. This article interprets Matthew 5:5 as an allusion to the Abrahamic promise of the inheritance of the land and the blessing of all the families of the earth mediated through Psalm 36 (LXX) and describes the figurative nature of the allusion using Harold Bloom’s revisionary ratios. Another version of the article will also be published in Kim, P & Ringe, S (eds), Literary encounters with the reign of God: Essays in honor of Robert C Tannehill, Harrisburg, PA: Trinity Press International (Forthcoming).
Le jeu des co ncidences : une vraisemblance à construire
Christine Otis
Temps Zéro : Revue d'étude des écritures Contemporaines , 2009,
Abstract: Dossier/Issue: 2 - Vraisemblance et fictions contemporaines. Une nouvelle adhésion pour les héritiers du soup on - Using the examples of "Nikoski" (Nicolas Dickner, 2005) and "La kermesse" (Daniel Poliquin, 2006), this article examines the construction of a parallel verisimilitude generated by the use of a multiplicity of coincidences. This particular verisimilitude manages to impose itself in spite of the presence of a number of unlikely events and may be considered as a type of generic verisimilitude (typical of a particular genre such as the detective novel or science fiction) taking effect in a particular fictional world. — à partir des exemples de "Nikolski" (Nicolas Dickner, 2005) et de "La kermesse" (Daniel Poliquin, 2006), l’article présente la construction d’une vraisemblance parallèle générée par l’utilisation d’une multitude de co ncidences. Cette vraisemblance particulière réussit à s’imposer malgré un certain degré d’invraisemblance et pourrait s’apparenter à la vraisemblance générique (propre à un genre particulier comme le roman policier ou de science-fiction par exemple), mais s’appliquant à un univers romanesque particulier.
Infinite Matrix Representations of Isotropic Pseudodifferential Operators
Otis Chodosh
Mathematics , 2011,
Abstract: We characterize the action of isotropic pseudodifferential operators on functions in terms of their action on Hermite functions. We show that an operator $A : S(\mathbb{R}) \to S(\mathbb{R})$ is an isotropic pseudodifferential operator of order r if and only if its "matrix" $(K(A))_{m,n} := < A\phi_n,\phi_m>_{L^2(\mathbb{R})}$ is rapidly decreasing away from the diagonal $\{m = n\}$, order $\frac {r}{2}$ in $m + n$, and where applying the discrete difference operator along the diagonal decreases the order by one. Additionally, we use this result to prove an analogue of Beal's theorem for isotropic pseudodifferential operators.
A Lack of Ricci Bounds for the Entropic Measure on Wasserstein space over the Interval
Otis Chodosh
Mathematics , 2011, DOI: 10.1016/j.jfa.2012.03.007
Abstract: This is a condensed form of the author's essay, which can be found at [arXiv:1105.2883]. We prove that the entropic measure constructed by von Renesse-Sturm over Wasserstein space on the unit interval (probability measures on the unit interval equipped with the 2-Wasserstein metric) does not admit generalized Ricci lower bounds in the sense of Lott-Villani-Sturm. We discuss why this is surprising, considering various heuristic arguments.
