Qualitative Accounts of School-Aged Children’s Diets during the COVID-19 Pandemic in Rural, Central, Kenya

The COVID-19 pandemic has caused disruption to food security in many countries, including Kenya. However, the impact of this on food provision to children at an individual level is unknown. This small study aimed to provide a qualitative snapshot of the diets of children during the COVID-19 pandemic. During completion of 24-h food recalls, with 15 families with children aged 5–8 years, caregivers were asked about changes they had made to foods given to their children due to the pandemic. Food recalls were analysed to assess nutrient intakes. Qualitative comments were thematically analysed. Most of the families reported making some changes to foods they provided to their children due to COVID-19. Reasons for these changes fell into three themes, inability to access foods (both due to formal restriction of movements and fear of leaving the house), poorer availability of foods, and financial constraints (both decreases in income and increases in food prices). The COVID-19 pandemic has affected some foods parents in rural Kenya can provide to their children.

War Crime Pardons and Presidential (Self-) Restraint

In 2019, then-President Trump pardoned three military officers for battlefield misconduct that could have been charged as war crimes. These were the first such pardons in American history and left many current and former members of the Armed Forces bewildered: these officers had all been charged by their military chains-of-command after sufficient evidence indicated culpability, and in two of the cases, military juries (“panels”) consisting of high-ranking officials with combat experience had convicted the officers and sentenced them to hefty federal prison terms. The granting of clemency under these circumstances has proven fraught with consequences – consequences adversely affecting the relationship between the president as commander-in-chief and the senior military leaders who cautioned against such extrajudicial mercy. Nevertheless, the president’s authority to do so, under Article II of the Constitution, is nearly without limit, and no other statute, case law precedent, or other formal restriction prevents him from doing so. This article approaches the problem from an assumption that neither the Constitution itself will be amended to carve out such crimes from the president’s reach, nor that Congress will amend the Uniform Code of Military Justice or the War Crimes Statute to chip away at this power by enacting administrative conditions on its exercise. Rather, this article suggests that the most likely and practical tool to prevent such pardons in the future is the reasonable, prudential exercise of restraint by the commander-in-chief. Several contingent factors, based on the possible timing of the pardon in relation to where the case is in the military justice process, are identified as a framework for exercising this prudential restraint notwithstanding the Constitutional authority to ignore it.

The steady aerodynamics of aerofoils with porosity gradients

This theoretical study determines the aerodynamic loads on an aerofoil with a prescribed porosity distribution in a steady incompressible flow. A Darcy porosity condition on the aerofoil surface furnishes a Fredholm integral equation for the pressure distribution, which is solved exactly and generally as a Riemann–Hilbert problem provided that the porosity distribution is Hölder-continuous. The Hölder condition includes as a subset any continuously differentiable porosity distributions that may be of practical interest. This formal restriction on the analysis is examined by a class of differentiable porosity distributions that approach a piecewise, discontinuous function in a certain parametric limit. The Hölder-continuous solution is verified in this limit against analytical results for partially porous aerofoils in the literature. Finally, a comparison made between the new theoretical predictions and experimental measurements of SD7003 aerofoils presented in the literature. Results from this analysis may be integrated into a theoretical framework to optimize turbulence noise suppression with minimal impact to aerodynamic performance.

A new species of Hemigrammus Gill, 1858 (Characiformes: Characidae) from the rio Madeira and rio Paraguai basins, with a redescription of H. lunatus

A new Hemigrammusis described from the rio Paraguai and rio Madeira basins, Mato Grosso and Rondônia States, Brazil. The new species is characterized by possessing a wide dark horizontal stripe across the eye, a vertically elongated humeral blotch, and 4-5 gill-rakers on upper branch and 9-10 on lower. The new species can be easily diagnosed from H. lunatus, the sympatric and morphologically most similar congener, by the shape of humeral blotch and the number of gill rakers. Data of the type material of both Hemigrammus lunatus and H. maxillaris, as well as extensive examination of specimens, allowed us to conclude that H. maxillarisis a junior subjective synonym of H. lunatus. A redescription of H. lunatus, as well as a formal restriction of its type locality, is provided. A putative monophyletic group within Hemigrammus, composed by H. barrigonae, Hemigrammus lunatus, H. machadoi new species, and H. ulreyi, named Hemigrammus lunatus group, is proposed based on overall body morphology and color pattern. Additionally, a discussion on the biogeographical relationships between the rio Paraguai and rio Guaporé basins is provided.

Rectitude Rights and Legitimacy: Reassessing and Reforming the Privilege against Self-Incrimination in English Law

The privilege against self-incrimination has always attracted controversy. Legal historians continue to disagree over its origins, and its justification has been keenly debated ever since Bentham's famous attack on it as a misguided concession to the guilty. This debate has recently entered a new and critical phase as the result of diametrically opposed developments by, on the one hand, the courts and legislature in England and, on the other, by the institutions of the European Convention of Human Rights. These developments can be summarised by saying that whereas the trend in England has been towards attrition and formal restriction of the privilege, the European Court of Human Rights has been reconstituting the privilege as an implicit element of the right to a fair trial under article 6.1 of the European Convention. The European decisions have the potential for significant expansion of the privilege, and they call into question the validity of several of the English developments.

On the theory of types

In this paper the theory of logical types will be examined, and certain departures from it will be suggested. Though the purpose of the paper is not primarily expository, an approach has been possible which presupposes no familiarity with special literature. Matters at variance with such an approach have been confined to appendices and footnotes.In the early pages the logical paradoxes will be considered—an infinite series of them, of which Russell's paradox is the first. Then Russell's simple theory of types will be formulated, in adaptation to a minimal set of logical primitives: inclusion and abstraction. Two aspects of the theory will be distinguished: an ontological doctrine and a formal restriction. It will be found that by repudiating the former we can avoid certain unnatural effects of the type theory—notably the reduplication of logical constants from type to type, and the apparent dependence of finite arithmetic upon an axiom of infinity. But the formal restriction itself has unnatural effects, which survive, even in an aggravated form, after the type ontology has been dropped. A liberalization of the formal restriction will be proposed which removes the more irksome of these anomalies.
