It is a revealing exercise to search for variations of the word “colonial” in the indexes and tables of contents of these recent monographs in Anglophone literary studies. As the subdiscipline begins to chronicle contemporary cultural developments in which the British Empire’s legacies grow ever-less marked, it is perhaps inevitable that the terms and concepts that governed the preceding phase of scholarship—colonialism, imperialism, and postcolonialism—begin to recede into the background. The sudden and sharp recession of these terms, however, raises fundamental questions regarding the study of English-language texts from the Caribbean, South Asia, West, and East Africa (among other locales). Among the foremost of such questions may be: does the term “postcolonialism” now designate a mere literary period, as opposed to being what scholars over the last several decades seem to have agreed it also is, namely a critical method? What are the effects and implications of this shift, wherein not just literary works newly arrived to a world scene still marked and structured by colonial legacies, but older ones long identified as definitionally “postcolonial,” are increasingly treated without such concepts and terms? Suggestions of answers to such questions arise throughout these three books, all of which seek to reconsider one of the keystone concerns of postcolonial studies, namely the relationship between contemporary Anglophone writing and the authors and texts of the British literary canon.

For given positive integers $r\ge 3$, $n$ and $e\le \binom{n}{2}$, the famous Erdős–Rademacher problem asks for the minimum number of $r$-cliques in a graph with $n$ vertices and $e$ edges. A conjecture of Lovász and Simonovits from the 1970s states that, for every $r\ge 3$, if $n$ is sufficiently large then, for every $e\le \binom{n}{2}$, at least one extremal graph can be obtained from a complete partite graph by adding a triangle-free graph into one part.

In this note, we explicitly write the minimum number of $r$-cliques predicted by the above conjecture. Also, we describe what we believe to be the set of extremal graphs for any $r\ge 4$ and all large $n$, amending the previous conjecture of Pikhurko and Razborov.

The ability and knowledge to manage financial tasks may be compromised in old age, especially when the need to navigate the care and social benefit systems increases. Managing financial tasks may consist of a variety of actions of both the older people themselves and their representatives, often family members. This study explored how financial tasks related to the care and everyday life of older people who need long-term care are managed by using the ideas of modalities of agency and distributed agency. We analysed interviews of 19 older persons and their family members with a qualitative case analysis. All the older persons who participated in the study distributed the agency in financial tasks among their family members, but to different levels and for different reasons. We identified three types of distributed agency – inevitable, assimilated and minimal distributed agency – in which the older persons’ knowledge about financial tasks and their ability to manage financial tasks differed. Within these types, the cases differed in terms of the know-how of the family members and the reasons why the older people’s knowledge about financial tasks or their ability to manage their financial tasks were diminished. We conclude that older persons with long-term care needs require help in regard to financial tasks, and the older people’s and their family members’ ability to manage financial tasks could be enhanced by making the benefit systems and online banking more user-friendly and by improving the help from care staff.

This survey paper is concerned with vortex shedding from bodies in unsteady flow due either to time dependent motion of the body in a still fluid or unsteady motion of the fluid about a fixed body. The fluid is treated as incompressible, and the main emphasis is on starting flows and oscillatory flows. Much of the discussion describes 2D flow around sections of long or slender bodies. The first part of the paper covers the inviscid flow scaling of the forces induced by vortex shedding in time dependent flows which drive the shedding. This is followed by application of Wu’s impulse integral of the moment of vorticity to predict the forces induced by vortex shedding from a body in both inviscid and viscous flows. Vortex shedding phenomena involving small amplitude, high-frequency oscillatory flow such as vortex-induced vibration (VIV) and fluid-structure interaction (FSI) are not included in this discussion as in these cases the unsteady flow controls rather than drives the vortex shedding and they are well covered elsewhere.

The second part of the paper describes a vortex force mapping (VFM) method derived by considering the Lamb–Gromyko formulation for the pressure contribution which allows the integral of the vorticity field to be restricted to regions which are not far from the body. It is applied to both inviscid and viscous flows. The section finishes with discussion of application of the VFM to the calculation of forces induced on bodies from flow field measurements, such as particle image velocimetry (PIV).

Rates of youth suicidal thoughts and behaviors (STBs) are rising, and younger age at onset increases vulnerability to negative outcomes. However, few studies have investigated STBs in early adolescence (ages 10–13), and accurate prediction of youth STBs remains poor. Network analyses that can examine pairwise associations between many theoretically relevant variables may identify complex pathways of risk for early adolescent STBs. The present study applied longitudinal network analysis to examine interrelations between STBs and several previously identified risk and protective factors. Data came from 9,854 youth in the Adolescent Brain Cognitive Development Study cohort (Mage = 9.90 ± .62 years, 63% white, 53% female at baseline). Youth and their caregivers completed an annual measurement battery between ages 9–10 through 11–12 years. Panel Graphical Vector Autoregressive models evaluated associations between STBs and several mental health symptoms, socioenvironmental factors, life stressors, and substance use. In the contemporaneous and between-subjects networks, direct associations were observed between STBs and internalizing symptoms, substance use, family conflict, lower parental monitoring, and lower school protective factors. Potential indirect pathways of risk for STBs were also observed. Age-specific interventions may benefit from prioritizing internalizing symptoms and early substance use, as well as promoting positive school and family support.

The terminal Ediacaran Period is signaled worldwide by the first appearance of skeletonizing tubular metazoan fossils, e.g., Cloudina Germs, 1972 and Sinotubulites Chen, Chen, and Qian, 1981. Although recent efforts have focused on evaluating the taxic composition and preservation of such assemblages from the southwestern United States, comparable forms reported in the 1980s from Mexico remain to be re-examined. Here, we reassess the latest Ediacaran skeletal materials from the La Ciénega Formation of the Caborca region in Sonora, Mexico, using a combination of analytical methods: optical microscopy of extracted fossils, thin-section petrography, scanning electron microscopy and energy dispersive X-ray spectroscopy, and X-ray tomographic microscopy. From our examination, we conclude that the La Ciénega hosts a polytaxic assemblage of latest Ediacaran tubular organisms that have been preserved through two taphonomic pathways: coarse silicification and calcareous recrystallization preserving finer details. Further, these fossils show signs that their shells might not have been inflexible or completely mineralized in vivo, and that they might also record tentatively interpreted predation traces in the form of drill holes or puncture marks. This work, along with ongoing efforts around the world, helps to provide a framework for biostratigraphic correlation and possible subdivision of the Ediacaran Period, and further shapes our view of metazoan evolution and ecology in the interval directly preceding the Cambrian explosion.

Let n be a positive integer and $\underline {n}=\{1,2,\ldots ,n\}$. A conjecture arising from certain polynomial near-ring codes states that if $k\geq 1$ and $a_{1},a_{2},\ldots ,a_{k}$ are distinct positive integers, then the symmetric difference $a_{1}\underline {n}\mathbin {\Delta }a_{2}\underline {n}\mathbin {\Delta }\cdots \mathbin {\Delta }a_{k}\underline {n}$ contains at least n elements. Here, $a_{i}\underline {n}=\{a_{i},2a_{i},\ldots ,na_{i}\}$ for each i. We prove this conjecture for arbitrary n and for $k=1,2,3$.

This paper argues that young people who claim state support in the UK are prone to accept the contemporary hegemonic conceptualisation within advanced capitalist societies, that individual behaviour and mindset are the key determinants of valorised labour market outcomes. The notion that the self is all encompassing and one can, and should, choose to overcome all challenges in life through self-improvement is particularly salient for recent generations of young people. Social policy reinforces this trend by encouraging changes in the individual to combat structural problems, and such ideology is present in the contemporary intensification of welfare conditionality. This paper draws upon secondary analysis of longitudinal qualitative data generated as part of the Welfare Conditionality Project (2013–2019) to demonstrate that young people who experience welfare conditionality are likely to individualise pathways to their future aspirations.

Staphylococcus aureus nasal carriers were randomized (1:1) to XF-73 or placebo nasal gel, administered 5x over ∼24hrs pre-cardiac surgery. S. aureus burden rapidly decreased after 2 doses (–2.2log10 CFU/mL; placebo –0.01log10 CFU/mL) and was maintained to 6 days post-surgery. Among XF-73 patients, 46.5% received post-operative anti-staphylococcal antibiotics versus 70% in placebo (P = 0.045).

This article contributes an account of a key moment in the development of venture capital. I argue the US Small Business Administration’s Task Force on Venture and Equity Capital for Small Business, established in 1976 and headed by William J. Casey, had an outsized impact on the development of modern venture capital and its close associations with the high technology sector. The Task Force’s 1977 report was influential in establishing both the figure of the venture capitalist and the business model of institutionally supported, limited partnership venture capital in the minds of policymakers, businesspeople, and the general public. This article traces the influence of one part of the Report: a prominently featured schematic model, entitled “Life Cycle of a New Enterprise: Model of a Growing and Successful Company, 1975-1976 Financial Market Conditions.” I trace the influence of the LCM as it spread through the developing high technology sector, as shown by its appearances in business publications, governmental reports, and congressional testimonies offered by industry leaders. The LCM was genericized away from its original authors and intentions, becoming part of the economic imaginary of the technology and innovation sector.
