We give a vanishing and classification result for holomorphic differential forms on smooth projective models of the moduli spaces of pointed K3 surfaces. We prove that there is no nonzero holomorphic k-form for $0<k<10$ and for even $k>19$. In the remaining cases, we give an isomorphism between the space of holomorphic k-forms with that of vector-valued modular forms ($10\leq k \leq 18$) or scalar-valued cusp forms (odd $k\geq 19$) for the modular group. These results are in fact proved in the generality of lattice-polarisation.
Independence is a key concept in probability. Conceptually, we think of two events as being independent if the outcome of one event doesn’t affect the outcome of the other and vice versa. Mathematically, we say that events A and B are independent if the probability that both occur is the product of the probabilities that each occurs. More precisely, P (A ∩ B) = P (A) (P (B) in which P () denotes the probability of the given event. Alternatively, we say that A and B are independent if the conditional probability that A occurs given that B has occurred, P (A | B), satisfies P (A | B) = P (A). That is, whether or not B occurs does not affect whether or not A occurs.
Estimate the risk for household transmission of Methicillin-Resistant Staphylococcus aureus (MRSA) following exposure to infected family members or family members recently discharged from a hospital.
Design:
Analysis of monthly MRSA incidence from longitudinal insurance claims using the Merative MarketScan Commercial and Medicare (2001–2021) databases.
Setting:
Visits to inpatient, emergency department, and outpatient settings.
Patients:
Households with ≥2 family members enrolled in the same insurance plan for the entire month.
Methods:
We estimated a monthly incidence model, where enrollees were binned into monthly enrollment strata defined by demographic, patient, and exposure characteristics. Monthly incidence within each stratum was computed, and a regression analysis was used to estimate the incidence rate ratio (IRR) associated with household exposures of interest while accounting for potential confounding factors.
Results:
A total of 157,944,708 enrollees were included and 424,512 cases of MRSA were identified. Across all included enrollees, exposure to a family member with MRSA in the prior 30 days was associated with significantly increased risk of infection (IRR: 71.03 [95% CI, 67.73–74.50]). After removing enrollees who were hospitalized or exposed to a family member with MRSA, exposure to a family member who was recently discharged from the hospital was associated with increased risk of infection (IRR: 1.44 [95% CI, 1.39–1.49]) and the risk of infection increased with the duration of the family member’s hospital stay (P value < .001).
Conclusions:
Exposure to a recently hospitalized and discharged family member increased the risk of MRSA infection in a household even when the hospitalized family member was not diagnosed with MRSA.
The editorial history of the two Pseudo-Clementine narratives known as the Recognitions and the Homilies is intricate, to say the least. From an ever-elusive “basic writing” spring two novelistic stories with extensive translation histories, subjected to significant editorial interventions, and anthologized alongside other late ancient and medieval texts. This article focuses on the addition of pseudonymous epistles as prefatory material for these Pseudo-Clementines and follows one of these letters in particular, the Epistula Clementis (Ep. Clem.). The Epistula Clementis accompanies the Latin Pseudo-Clementine Recognitions in a host of medieval anthologies concerned with Petrine hagiography and ecclesial succession, as well as histories, dialogues, and epistolary texts with anti-Judaic resonances. I argue that the Epistula Clementis, as a prefatory text, was integral to the success of the Recognitions in these later anthologies, highlighting the transformative power of the preface upon its associated text as well as the hermeneutical force of the anthology itself.
Through a commingled, fragmentary assemblage of skeletal remains (MNI = 9) recovered from a 1999 salvage excavation, this article explores the lives and deaths of individuals interred at the Brentwood Poor Farm, Brentwood, New Hampshire (1841–1868). This work demonstrates that bioarchaeological analyses of smaller samples can provide nuanced accounts of marginalization and institutionalization even with scant historical records. The skeletal analysis presented here is contextualized within the larger history of the American poor farm system and compared to similar skeletal samples across the United States. The hardships these individuals faced—poverty, otherness, demanding labor—were embodied in their skeletal remains, manifesting as osteoarthritis, dental disease, and other signs of physiological stress. These individuals’ postmortem fates were also impacted by status; they were interred in unmarked graves, disturbed by construction, and once recovered, were again forgotten for more than 20 years.
On 7 December 2022, the United Nations General Assembly adopted a treaty known as the Beijing Convention governing the recognition abroad of the international effects of judicial sales of ships. This article explores the rationale for a specific Convention on this issue, and its interaction with other relevant international conventions. It then analyses the recognition approach adopted by the Convention and evaluates its potential strengths and weaknesses. While some provisions might need further consideration, the overall conclusion is that the Beijing Convention has the potential to strengthen the legal certainty of the purchaser's title obtained via this sale mechanism and thus help debt recovery. Although common law jurisdictions might find it at odds with some of their features, the expected benefits from ratifying it seem to outweigh these issues and are already prompting a steady number of signatures, including those of China, the European Union and Singapore.
This is the transcript of an interview with Glasgow-based Australian composer Dr Jane Stanley. The interviewer is Dr Judith Bishop, an Australian poet and lyricist whose words appear in two of the works discussed: ‘14 Weeks’ (from Interval (UQP, 2018) and ‘The Indifferent’ (from Event (Salt Publishing UK, 2007)). The interview was recorded at the University of Glasgow on 29 May 2023 and edited for clarity, length and concision. It was recorded a day after the world premiere of Jane Stanley's 14 Weeks at the Glasgow School of Art Choir Composeher concert in City Halls, Glasgow. In response to a recent survey which revealed huge gender inequalities in the granting of music commissions, Composeher had commissioned seven female composers to write choral works of around ten minutes, of which 14 Weeks was one. The interview ranges widely, from the composer's textural style to her creative process, and touches on her forthcoming composer portrait album, to be released by Delphian Records in 2024.
The loop space of a string manifold supports an infinite-dimensional Fock space bundle, which is an analog of the spinor bundle on a spin manifold. This spinor bundle on loop space appears in the description of two-dimensional sigma models as the bundle of states over the configuration space of the superstring. We construct a product on this bundle that covers the fusion of loops, i.e. the merging of two loops along a common segment. For this purpose, we exhibit it as a bundle of bimodules over a certain von Neumann algebra bundle, and realize our product fibrewise using the Connes fusion of von Neumann bimodules. Our main technique is to establish novel relations between string structures, loop fusion, and the Connes fusion of Fock spaces. The fusion product on the spinor bundle on loop space was proposed by Stolz and Teichner as part of a programme to explore the relation between generalized cohomology theories, functorial field theories, and index theory. It is related to the pair of pants worldsheet of the superstring, to the extension of the corresponding smooth functorial field theory down to the point, and to a higher-categorical bundle on the underlying string manifold, the stringor bundle.
The new species Caloplaca tswaluensis is described from Tswalu Kalahari Reserve, Northern Cape Province, South Africa. Caloplaca tswaluensis occurs on the trunks of Vachellia erioloba (camelthorn) trees and is characterized by its 3-septate to quadrilocular ascospores. Molecular data indicate that the new species is placed in the subfamily Teloschistoideae but cannot be assigned to any existing genus and, because its systematic position is unclear, we choose to describe it in Caloplaca s. lat. Caloplaca tswaluensis is compared with other crustose Teloschistaceae species with plurilocular ascospores.
This article explores the sudden spate of stories concerning the so-called “blue gum negro” (the Blue Gum) that circulated in the national press from the late 1880s to the late 1890s. These reports concerned purportedly blue-gummed, Black assailants, whose bite was alleged to be poisonous, and of whom African Americans were supposedly terrified. This article argues that, although these narratives reinforced white notions of Black criminality and credulity, they marked a particular moment of racialization, in which fears of bodily contagion, generated by the recent revolution in germ theory, were harnessed to notions of embodied racial difference, to express and galvanize white anxieties about racial impurity. Because Blue Gums embodied dysgenic menace, white journalists and writers were often reluctant to disavow their existence, instead capitalizing on the slippage between figurative and literal language that characterized discourse on race. However, in appropriating Black culture and presenting a figure from folklore as a racial type, white writers betrayed not only the essentially superstitious character of racial thought but also the interwoven nature of dominant and subjugated cultures in the United States.
Recent work in social epistemology has drawn attention to various problematic social epistemic phenomena that are common within online networks. Nguyen (2020) argues that it is important to distinguish epistemic bubbles from echo chambers. An epistemic bubble is an information structure that merely lacks information or sources that would be relevant or important to the user. An echo chamber is a structure in which dissenting opinions are, not necessarily absent, but actively undermined, for example by instilling attitudes of distrust towards their adherents. Because of this, echo chambers are thought to be especially difficult to escape. In contrast, according to Nguyen, it is relatively easy to shatter an epistemic bubble: one simply introduces the missing information. In this paper, I argue that it is more difficult to shatter an epistemic bubble than has been recognised in the literature. The reason for this is the relationship between epistemic bubbles and interpretative resources. Despite their epistemic drawbacks, it is comparatively easy to gain knowledge from sources inside one's epistemic bubble because agents within a bubble share common ground. In contrast, it can be very difficult to gain knowledge from sources outside of one's bubble because interlocutors on the outside are less likely to have the shared context needed to facilitate communicative success. I argue that this problem suggests a different way to understand the nature of epistemic bubbles and our prospects for escaping them.
Trommeslåtter (drum tunes) have played a vital role in Norwegian traditional music for several hundred years. This article examines the development and performance of drum tunes in Norway, with a special focus on the work of Johannes Sundvor in transcribing drum music. We present several examples and analyse tunes from Sundvor’s collection. We also demonstrate how this Norwegian drum tradition is related to a tradition of European military drumming. The article concludes with a discussion of aspects of interpretation and an outline of the status of drum tunes today.
