Reframing Kurtzâs Painting: Colonial Legacies and Minority Rights in Ethnically Divided Societies
Minority rights constitute some of the most normatively and economically important human rights. Although the political science and legal literatures have proffered a number of constitutional and institutional design solutions to address the protection of minority rights, these solutions are characterized by a noticeable neglect of, and lack of sensitivity to, historical processes. This Article addresses that gap in the literature by developing a causal argument that explains diverging practices of minority rights protections as functions of colonial governmentsâ variegated institutional practices with respect to particular ethnic groups. Specifically, this Article argues that in instances where colonial governments politicize and institutionalize ethnic hegemony in the pre-independence period, an institutional legacy is created that leads to lower levels of minority rights protections. Conversely, a uniform treatment and depoliticization of ethnicity prior to independence ultimately minimizes ethnic cleavages post-independence and consequently causes higher levels of minority rights protections. Through a highly structured comparative historical analysis of Botswana and Ghana, this Article builds on a new and exciting research agenda that focuses on the role of long-term historio-structural and institutional influences on human rights performance and makes important empirical contributions by eschewing traditional methodologies that focus on single case studies that are largely descriptive in their analyses. Ultimately, this Article highlights both the strength of a historical approach to understanding current variations in minority rights protections and the varied institutional responses within a specific colonial government
Satellite potentials for hypergeometric Natanzon potentials
As a result of the so(2,1) of the hypergeometric Natanzon potential a set of
potentials related to the given one is determined. The set arises as a result
of the action of the so(2,1) generators.Comment: 9 page
Breakdown of the semiclassical approximation during the early stages of preheating
The validity of the semiclassical approximation is investigated during the preheating phase in models of chaotic inflation using a modification of a criterion previously proposed for semiclassical gravity. If the modified criterion is violated then fluctuations of the two-point function for the quantum elds are large and the semiclassical approximation is not valid. Evidence is provided that the semiclassical approximation breaks down during the early stages of preheating, well before either scattering effects or backreaction effects are important

Patientsâ experiences of clinical team meetings (ward rounds) at an adult in-patient eating disorders ward: mixed-method service improvement project
Aims
Ward rounds are key to treatment-related decision-making, but are often stressful. This project aimed to explore and improve patientsâ experiences of the clinical team meeting (CTM; historically known as ward round) in an adult in-patient eating disorders unit. A mixed-method approach was adopted with in vivo observations, two focus groups and an interview. Six patients participated. Two former patients contributed to data analysis, co-production of service improvement initiatives and write-up.
Results
The mean CTM duration was 14.3 min. Patients spoke half of the time, followed by psychiatry colleagues. âRequestâ was the most discussed category. Three themes were identified: CTMs are important but impersonal, a sense of palpable anxiety was generated and staff and patients had divergent views regarding CTM goals.
Clinical implications
The co-produced changes to CTMs were implemented and improved patient's experiences despite COVID-19 challenges. Factors beyond CTMs, including the ward's power hierarchy, culture and language, need addressing to facilitate shared decision-making

Magnetic-field-induced reduction of the exciton polarization splitting in InAs quantum dots
By the application of an in-plane magnetic field, we demonstrate control of
the fine structure polarisation splitting of the exciton emission lines in
individual InAs quantum dots. The selection of quantum dots with certain
barrier composition and confinement energies is found to determine the magnetic
field dependent increase or decrease of the separation of the bright exciton
emission lines, and has enabled the splitting to be tuned to zero within the
resolution of our experiments. Observed behaviour allows us to determine
g-factors and exchange splittings for different types of dots.Comment: 12 pages, 3 figure
Designing the ideal model for assessment of wound contamination after gunshot injuries: a comparative experimental study
<p>Abstract</p> <p>Background</p> <p>Modern high-velocity projectiles produce temporary cavities and can thus cause extensive tissue destruction along the bullet path. It is still unclear whether gelatin blocks, which are used as a well-accepted tissue simulant, allow the effects of projectiles to be adequately investigated and how these effects are influenced by caliber size.</p> <p>Method</p> <p>Barium titanate particles were distributed throughout a test chamber for an assessment of wound contamination. We fired .22-caliber Magnum bullets first into gelatin blocks and then into porcine hind limbs placed behind the chamber. Two other types of bullets (.222-caliber bullets and 6.5 Ă 57 mm cartridges) were then shot into porcine hind limbs. Permanent and temporary wound cavities as well as the spatial distribution of barium titanate particles in relation to the bullet path were evaluated radiologically.</p> <p>Results</p> <p>A comparison of the gelatin blocks and hind limbs showed significant differences (<it>p </it>< 0.05) in the mean results for all parameters. There were significant differences between the bullets of different calibers in the depth to which barium titanate particles penetrated the porcine hind limbs. Almost no particles, however, were found at a penetration depth of 10 cm or more. By contrast, gas cavities were detected along the entire bullet path.</p> <p>Conclusion</p> <p>Gelatin is only of limited value for evaluating the path of high-velocity projectiles and the contamination of wounds by exogenous particles. There is a direct relationship between the presence of gas cavities in the tissue along the bullet path and caliber size. These cavities, however, are only mildly contaminated by exogenous particles.</p
