In this paper, I attempt to interpret Kant’s early reported thesis that the historical practice of senicide (i.e., killing the elderly) among certain Inuit communities constituted a ‘loving service’ and was ‘to some degree justified’ insofar as it was carried out to prevent one’s parents from facing a ‘more ignominious death’. On my interpretation, Kant’s verdict on Inuit senicide sheds new light on a core idea within his mature ethics – that persons are obligated to preserve themselves for as long as they remain a subject of duty. As I argue, Kant’s verdict implies that those subject to senicide were no longer bound by the duty of self-preservation insofar as they were no longer able to live as persons with inviolable moral dignity. If my argument holds, this invites further exploration of the relationship between Kant’s notion of dignity and the duty of self-preservation in the broader context of end-of-life decision-making.
Metacercariae of Diplostomum spp. are globally distributed pathogens that infect the eyes and brains of fish and lampreys, including populations in northern latitudes. This study investigated the species diversity and distribution of Diplostomum in juvenile Atlantic salmon Salmo salar and brown trout Salmo trutta from 11 rivers in northwestern Russia. Phylogenetic analyses revealed two diplostomid species: ‘D. mergi’ Lineage 3 and D. numericum. It is the first record of these species in the Russian part of the Arctic. These species, previously recorded in Western/Central Europe and Russian Karelia, likely spread via major migratory flyways of their avian definitive hosts. The species composition of Diplostomum metacercariae in riverine salmonids of the studied region was notably poorer than in lacustrine salmonids from other Arctic localities. The haplotype distributions of recorded Diplostomum species showed no spatial structuring, consistent with broad-scale dispersal processes.
Contention about representations of history and the purposes of History education has long surrounded Japanese History textbooks. From 2012, the ascent of powerful nationalist Prime Minister Abe Shinzō raised questions about possible political pressures on textbook content. This article analyzes recent market-leading junior high school and high school History textbooks to discover how pedagogical format and content related to controversial topics or national identity have changed since 2012. It finds that leading junior high school textbooks have largely maintained their representation of controversial topics, while developing investigative, analytic pedagogical approaches. Coverage of some aspects of ethnic and cultural diversity within Japan has increased. Following the implementation of a new curriculum from 2022, some high school textbooks for the new compulsory subject “Integrated History” facilitate a more analytic, “disciplinary” pedagogy than previously evident in compulsory high school History. Nonetheless, an “enhancing collective memory” approach to History pedagogy remains central throughout secondary education. These developments suggest that power over History education in Japan is distributed between a range of actors. The state, the market, and social pressures all influence the content of History textbooks in Japan.
This article traces the contours of the history of women’s education in England and Ireland in the period 1850-2000, mapping dominant themes and key inflection points. Positing a framework for reading degrees of change over time, we propose four interrelated lenses: access, curriculum, institutional presence, and networks. Drawing on key contributions to the field, we argue that women’s engagement with higher education has followed a complex and uneven trajectory, reflective of the shifting sands of attitudes and accommodations toward women across time, space, and discipline.
Confronting and eliminating the injustice of the slave trade and slavery were crucial to the mission of the Church Missionary Society and its mid-19th-century ‘Upper Niger’ missionary agents in Nigeria. The native CMS missionaries on the Niger, led by Samuel Adjai Crowther, held a dual identity as subjects of the British Government (via the British colony of Sierra Leone) and as native members in their host communities. They were freed slaves or children of freed slaves who returned from Sierra Leone to serve in the natal regions from which they or their parents had been deported as slaves. They were the ones who purveyed the Christian ‘laws of God’. The influence of the British government, manifest, for example, in British consular oversight and in the frequent visits of imperial gunboats, also constituted them into subjects with the responsibility to espouse British law, ‘the laws of England’, and especially abolition and anti-slavery, in their Niger mission stations. But they were politically dependent on the support and approval of their politically autonomous hosts, whose structure of justice, ‘the laws of the land’, still accommodated slavery. This essay explores how these native CMS missionaries navigated among these conflictual juridical and moral spheres of responsibility.
Our thesis is that the degree of permissible interaction between government and religion and its policy implications is most strikingly documented in the educational arena. To support our claim, we make three arguments: (1) by the early 1970s, New York, Pennsylvania, Rhode Island, and other states were experimenting with accommodationist policies in education that neither increased religious divisiveness nor denied religious freedom. These policy experiments contributed to the Supreme Court’s new understanding of religious accommodation under the First Amendment; (2) beginning in the late 1970s, a scholarly reappraisal of the establishment clause—based on a close reading of the debates over the First Amendment in Congress and the states—was demonstrating that reasonable governmental accommodations, particularly in education, would not violate the establishment clause; and (3) that periodizing the establishment clause’s history, by focusing on state-level innovations and scholarly reinterpretations, enhances the understanding of the policy developments of the First Amendment, particularly in the educational field.
In this paper, we perform a Floquet-based linear stability analysis of the centrifugal parametric resonance phenomenon in a Taylor–Couette system subjected to a time-quasiperiodic forcing where both the inner and outer cylinders are oscillating with the same amplitude and different angular velocities given respectively by $\varOmega _0 \cos (\omega _1t)$ and $\varOmega _0 \cos (\omega _2t)$. In this context, the frequencies $\omega _1$ and $\omega _2$ are incommensurate, where the ratio $\omega _2/\omega _1$ is irrational. Taking into account non-axisymmetric disturbances, a new set of partial differential equations is derived and solved using the spectral method along with the Runge–Kutta numerical scheme. The obtained results in this framework show that this forcing triggers new and numerous reversing and non-reversing Taylor vortex flows arising via either synchronous or period-doubling bifurcations. A rich and complex dynamics is found owing to strong mode competition between these modes that alters significantly the topology of the marginal stability curves. The latter exhibit a multitude of small and condensed parabolas, giving rise to several codimension-two bifurcation points, discontinuities and cusp points in the stability diagrams. Furthermore, a proper tuning of the frequency ratio leads to a significant control of both the instability threshold and the axisymmetric nature of the primary bifurcation. Moreover, using a local quasi-steady analysis when the cylinders are slowly oscillating, intermittent instabilities are detected, characterised by spike-like behaviour in the stability diagrams with several successive growths, dampings and periods of quietness. In this limit case, the inner cylinder drive becomes the responsible forcing of the Taylor vortices’ formation where the calculated critical instability parameters correspond to those of the inner oscillating cylinder case with fixed outer cylinder. The potentially unstable regions between the cylinders are determined on the basis of the Rayleigh discriminant, where an excellent agreement with the linear stability analysis results is pointed out.
Inspired by Bhatt–Scholze [BS22], in this article, we introduce prismatic cohomology for rigid analytic spaces with l.c.i. singularities, with coefficients over Fontaine’s de Rham period ring ${\mathrm {B_{dR}^+}}$.
This note argues that imitation of Ausonius’ Cento nuptialis in the Peruigilium Veneris establishes 374 c.e. as the terminus post quem for the Peruigilium Veneris. The note enlarges on the argument of Danuta Shanzer, who identified debts to Ausonius in the Peruigilium Veneris and dated the latter poem accordingly: the approach is to locate evidence for Ausonian imitation that Shanzer missed, and thus to reinforce and confirm her position. While the note does not propose a poet for the Peruigilium Veneris, it shows that certain figures to whom the work is commonly attributed, notably Florus and Tiberianus, cannot be its author.
Let X be an uncountable Polish space and let $\mathcal {I}$ be an ideal on $\omega $. A point $\eta \in X$ is an $\mathcal {I}$-limit point of a sequence $(x_n)$ taking values in X if there exists a subsequence $(x_{k_n})$ convergent to $\eta $ such that the set of indexes $\{k_n: n \in \omega \}\notin \mathcal {I}$. Denote by $\mathscr {L}(\mathcal {I})$ the family of subsets $S\subseteq X$ such that S is the set of $\mathcal {I}$-limit points of some sequence taking values in X or S is empty. In this article, we study the relationships between the topological complexity of ideals $\mathcal {I}$, their combinatorial properties, and the families of sets $\mathscr {L}(\mathcal {I})$ which can be attained. On the positive side, we provide several purely combinatorial (not depending on the space X) characterizations of ideals $\mathcal {I}$ for the inclusions and the equalities between $\mathscr {L}(\mathcal {I})$ and the Borel classes $\Pi ^0_1$, $\Sigma ^0_2$, and $\Pi ^0_3$. As a consequence, we prove that if $\mathcal {I}$ is a $\Pi ^0_4$ ideal then exactly one of the following cases holds: $\mathscr {L}(\mathcal {I})=\Pi ^0_1$ or $\mathscr {L}(\mathcal {I})=\Sigma ^0_2$ or $\mathscr {L}(\mathcal {I})=\Sigma ^1_1$ (however we do not have an example of a $\Pi ^0_4$ ideal with $\mathscr {L}(\mathcal {I})=\Sigma ^1_1$). In addition, we provide an explicit example of a coanalytic ideal $\mathcal {I}$ for which $\mathscr {L}(\mathcal {I})=\Sigma ^1_1$. On the negative side, since $\mathscr {L}(\mathcal {I})$ contains all singletons, it is immediate that there are no ideals $\mathcal {I}$ such that $\mathscr {L}(\mathcal {I})=\Sigma ^0_1$. On the same direction, we show that there are no ideals $\mathcal {I}$ such that $\mathscr {L}(\mathcal {I})=\Pi ^0_2$ or $\mathscr {L}(\mathcal {I})=\Sigma ^0_3$. In fact, for instance, if $\mathcal {I}$ is a Borel ideal and $\mathscr {L}(\mathcal {I})$ contains a non $\Sigma ^0_2$ set, then it contains all $\Pi ^0_3$ sets. We conclude with several open questions.
Intergenerational programs can support social connectedness, and an important element is engaging in activities together, known as ‘co-occupation’. To address gaps in the literature, we explored how older adults and university students living together in a retirement home enacted co-occupations, the factors that shaped the co-occupations, and how the co-occupations affected intergenerational relationship-building and connections. We conducted a focused ethnography using a constructivist-interpretivist paradigm, interviews with university students and older adults, and on-site observations. We analysed data using reflexive thematic analysis. Co-occupations were critical in creating connections and mutually beneficial intergenerational relationships. Participants often transformed co-occupations to promote interactions. Important features of intergenerational housing appear to be access to co-occupations that are structured and unstructured, flexibility to modify co-occupations, and physical spaces that promote co-occupation. This research illustrates how co-occupation within intergenerational housing programs can support connection and relationship-building. Findings can be applied within intergenerational housing and other intergenerational programs.
This article confronts the idea—especially widespread in the field of political philosophy, amongst Italian philosophers associated with feminism of difference, and in general narratives of 1970s Italian feminism—that Carla Lonzi was an anticipator of the Italian thought of sexual difference. Contra seminal texts like Non credere di avere dei diritti (1987) and scholars affiliated with the Libreria delle Donne di Milano and the Diotima philosophical collective, I illustrate how Lonzi was extraneous to the theoretical foundations and practices of “femminismo della differenza.” Notions of the symbolic mother, practices of disparity and ‘entrustment’, concerns with bringing into existence a female symbolic order—which would ground the development of the thought of sexual difference—were either absent in Lonzi’s writings or contested by her. While Lonzi’s work has increasingly been used to advance essentialist, gender-critical arguments by philosophers close to feminism of difference (for whom her work seemingly provides support against the very existence of non-binary, queer, and trans lives), I show how her approach to sexual difference departed significantly from such interpretations and can rather be more convincingly understood through Simone de Beauvoir.
We argue that scholars involved in debates on Kant’s writings on race and racism are deeply entangled with a tacit methodological debate about the use of a ‘priority principle’. We identify three variants of the priority principle in Kant scholarship. To illustrate, we focus on interpretations of Kant’s Physical Geography. The methodological approaches we analyse offer three opposite and mutually exclusive interpretative recommendations. We articulate a taxonomy of methods commonly employed and suggest that focusing on individual texts reveals value-laden methodological assumptions guiding the debate. To address substantive issues surrounding Kant’s raciology, we suggest commentators should carefully justify their methodological choices.
We analysed cardiac MRI and catheterisation variables during pre-Fontan evaluations for associations with major adverse cardiac events including Fontan takedown, mechanical circulatory support, heart transplantation, or death.
Methods:
In this single-centre retrospective study, we gathered pre-operative MRI and catheterisation data for all patients who underwent Fontan operation at Children’s Medical Center, Dallas, from April 2017 to November 2022. Patients were grouped according to the presence or absence of adverse events, and MRI and catheterisation parameters were compared between groups. We used the Mann–Whitney U Test for non-parametric data, Student’s T-test for parametric continuous variables, and Fisher’s Exact Test for categorical variables.
Results:
Of the 119 combined evaluations, 81 proceeded with Fontan palliation. Adverse events were recorded in 10% of patients (n = 8). One had a Fontan takedown, one underwent transplant, one required mechanical circulatory support, and five died in a median 21-month follow-up. Factors significantly associated with adverse events included heterotaxy syndrome (p = 0.04), higher combined pulmonary vascular resistance (p = 0.03), and moderate-severe (≥30%) atrioventricular valve regurgitation (p = 0.046). While combined pulmonary vascular resistance calculated from both catheterisation and MRI data predicted outcome, pulmonary vascular resistance calculated using data solely from catheterisation showed no discriminative ability.
Conclusions:
Post-Fontan major adverse cardiac events were associated with heterotaxy syndrome, higher combined pulmonary vascular resistance, and moderate-severe atrioventricular valve regurgitation identified on pre-Fontan MRI and catheterisation. Combined pulmonary vascular resistance using transpulmonary gradient from catheterisation data and effective pulmonary blood flow from MRI data may help predict outcome.
