Previous studies have indicated that young middle-class Japanese women’s stronger willingness to study English in the West can be attributed to Japan’s gender inequality and women’s longing for gender-equal Western societies. This literature-based study highlights an overlooked group of non-elite young Japanese women who make grassroots efforts to achieve upward mobility by studying English in Western English-speaking countries while participating in working holiday programs. Although socioeconomic and educational inequalities exist among international students, they are often invisible, particularly among the youth from developed countries such as Japan. This study provides new insights into the factors that influence unprivileged young Japanese women’s investment in studying English abroad. For example, women’s beliefs in the power of English skill development and overseas work experience are derived from the misconception dominant in Japan’s non-multilingual corporate world that anyone with self-acquired English skills can perform bilingual jobs, such as interpreting. This factor enables academic and commercial agents (e.g., women’s magazines and college prospectuses) to produce pro-women discourse that even non-elite young women can achieve career mobility by gaining English skills and overseas work experience. Implications are provided for international English education stakeholders positioned to emphasize global English promises while obscuring the reality of widening disparities. The gap between university-based elite researchers and non-elite research participants is also discussed as a challenge to the much-needed attempt to further examine the impact of global and localized English ideology on non-elite English learners’ grassroots efforts toward upward mobility.
Despite being outlawed, attacks on cultural heritage remain a pervasive feature in atrocity contexts, the effects of which are compounded by a relative deficit of accountability at the international level. To remedy this gap, the Office of the Prosecutor (OTP) of the International Criminal Court (ICC) issued Policy on Cultural Heritage. However, crimes against cultural heritage are not fully articulated in the Court’s governing instruments. To leverage the protective scope of the Court, the Policy adopts a human rights understanding of cultural heritage which I frame in terms of distinctive relationships between heritage and atrocity crimes. The Policy fertilises a second argument shorthanded as world-building. Against world-destruction, the Policy erects an accountability architecture. Conceptually, it foregrounds an understanding of the world as a cultural construct around which social relations are organised. Crimes against heritage undercut the very notion of what it means to be human; disrupt cultural identification, transmission, and development processes; and deny present and future generations the ability to be specific kinds of cultural human beings. In those regards, this article adds to the world society research agenda of English School theory by examining how the Policy more fully develops the Court’s role as an agent for humanity.
This paper describes challenges and opportunities for data collection during a disaster, focusing on how young adults in the United States navigated the initial period of the COVID-19 pandemic--a disaster which introduced significant uncertainty and precarity both for individuals and the research process.
Methods
This paper draws on lessons from a small exploratory study which used journaling techniques as a data collection tool.
Results
Journaling addressed 3 key challenges to collecting data during a public health crisis: 1) accessing respondents when preparation time and resources are limited; 2) ensuring protection for both participants and researchers in a context when human interaction is severely constrained; and 3) needing both rapid response and flexibility in research design and data collection.
Conclusions
Journaling techniques are a feasible, efficient and effective tool that can be adapted and utilized in various disaster contexts, including other pandemics and extreme climate events.
We investigate enstrophy variations by collapse of point vortices in an inviscid flow and, in particular, focus on the enstrophy dissipation that is a significant property characterising two-dimensional (2-D) turbulent flows. To reveal the vortex dynamics causing the enstrophy dissipation, we consider the dynamics of point vortices, whose vorticity is concentrated on points and dynamics on the inviscid flow, governed by the point-vortex system. The point-vortex system has self-similar collapsing solutions, which are expected to be a key to understand the enstrophy dissipation, but the collapsing process cannot be described by solutions to the 2-D Euler equations. We thus consider the 2-D filtered-Euler equations, which are a regularised model of the 2-D Euler equations, and their point-vortex solutions. The preceding studies (Gotoda and Sakajo, J. Nonlinear Sci. 2016, vol. 26, pp. 1525–1570, Gotoda and Sakajo, SIAM J. Appl. Math. 2018, vol. 78, 2105–2128) have proven that there exist three point-vortex solutions to the filtered model such that they converge to self-similar collapsing orbits in the three point-vortex system and dissipate the enstrophy at the event of collapse in the zero limit of the filter parameter. In this study, we numerically show that the enstrophy dissipation by the collapse of point vortices could occur for the four and five vortex problems in a filtered model. Moreover, we show the detailed convergence process of the point vortices for gradually decreasing filter parameters, which provides a new insight for the three vortex problem. In addition, numerical computations suggest that the enstrophy dissipation is caused by collapse of separated point vortices with the negative interactive energy.
Three decades after the Good Friday Agreement, repositories such as the Linen Hall Library in Belfast have built collections that explore the impact of sectarian violence and the path to peace. While the Northern Ireland Political Collection is a must for any scholar of The Troubles, the library is also filled with resources for British scholars in a number of areas. One such innovative resource – the ExtraORDINARY Women collection – helps scholars answer questions of how gender history interacts with contemporary and local political history. The collection documents the history of a range of women's political and civil rights in holdings that range from 1965 to the present.
Transcatheter pulmonary valve implantation has emerged as a minimally invasive and preferred therapeutic option for patients with dysfunction of previously repaired right ventricular outflow tracts. The Myval™ Octacor valve is a new device designed for this purpose, though limited reports exist regarding its use in the pulmonary position.
Aims:
To report the immediate and short-term outcomes of percutaneous pulmonary valve implantation using the Myval™ Octacor valve in patients with severe right ventricular–pulmonary artery conduit or pulmonary valve bioprosthesis dysfunction.
Methods:
This was a single-centre retrospective review of data obtained from case files.
Results:
The Myval™ Octacor valve was used in ten patients with a mean age of 34.5 ± 7.4 years. The median procedure duration and fluoroscopy time were 146 minutes and 30.5 minutes, respectively. The median Z-score for valves used was −0.5. The median right ventricular systolic pressure decreased from 68.5 mmHg pre-procedure to 33 mmHg post-procedure. The median peak instantaneous gradient across the right ventricular outflow tract or conduit decreased from 30 mmHg to 6.5 mmHg. There were no reported incidences of frame fracture, conduit rupture, device embolisation, or endocarditis.
Conclusion:
This is the first UK experience of using the new-generation Myval™ Octacor valve in percutaneous pulmonary valve implantation. The results demonstrate the valve’s safety and clinical efficacy, with favourable outcomes in terms of procedural success, haemodynamic improvement, and echocardiographic findings.
Building on Maria Mälksoo’s influential 2015 article “Memory Must Be Defended”: Beyond the Politics of Mnemonical Security (Security Dialogue, 46(3), 221–237), the volume Defending Memory in Global Politics: Mnemonical In/Security and Crisis, edited by Erica Resende, Dovilė Budrytė, and Douglas Becker, examines contemporary politics of memory politicisation and securitization captured in eleven case studies, structured according to actor types (state versus non-state). The book’s primary conceptual proposition is predicated on the concept “mnemonic in/security”. As with the broader concept of ontological security, this term encapsulates the tensions between the imperative to safeguard a collective memory against perceived external and internal threats to create and stabilize collective identities, and the inherent vulnerabilities and marginalizations that accompany the selection of memories to be enshrined in such an effort. In this perspective, conflicts over recognition, or even mnemonic “battles,” are inevitable. Such struggles manifest themselves, for instance, when governments promulgate specific memory narratives that neglect or reinterpret historical wrongdoings against other states. However, they can also occur within political communities. In such cases, political actors—particularly following periods of internal crisis and violence—promote amnesia or, conversely, memorialization of historical events. The purpose of this promotion is to legitimize a political order and its hegemonic forces.
This article introduces the scope, content, and capabilities of a new born-digital archive. The Medieval Londoners Database (MLD) uses an online platform to collect from and connect to both documents (printed and archival) and digitized resources (such as British History Online and the History of Parliament Online). As a digital prosopography, MLD is a freely available resource that offers sophisticated search options to discover more about the lives of both the civic elite and ordinary individuals who resided in the city of London or its suburbs of Southwark and Westminster between ca. 1100 and 1520. MLD exemplifies how digitization and the semantic web enhance historical research by creating super-powered archival collections that are ever-expanding, accessible via multiple entry points, and able to facilitate highly analytical research.
Pseudocyesis, also known as false pregnancy, is defined as the belief of being pregnant with physical signs and symptoms in the absence of a confirmed pregnancy. Notable cases include Queen Mary, who suffered from phantom pregnancies under societal pressure to conceive in the 16th century. Although now extremely rare, at its peak it accounted for 1 in 250 pregnancies following the Second World War, and was thought to be linked to heightened gender norms and sociocultural expectations around motherhood during this time. Pseudocyesis presents with complex and unique diagnostic challenges in clinical practice. It differs from delusional pregnancy, which is a fixed belief of pregnancy without physical signs or symptoms. The condition is often associated with infertility, psychological distress and neuro-endocrine conditions affecting the reproductive system. Management requires a multidisciplinary approach, integrating psychological support and addressing underlying reproductive health issues.
In 1805, during a lull in hostilities between England and France, minor Warwickshire landowner and slaveholder Bertie Greatheed was on a European tour with his family when his son died, leaving behind an illegitimate child. Greatheed acquired his granddaughter from her Dresden-based mother and brought the child up as his own. This article revisits Steedman's earlier scholarship on Greatheed, which focused on questions of domestic service, through the lens of slavery. It uses the seventeen volumes of his diary-writing compiled between 1805 and 1825 to explore the connections between Greatheed's ownership of enslaved people on his St. Kitts estate and his possession and nurturing of his grandchild. It considers the contradiction between Greatheed's position as an abolitionist and his profit from slavery and slave ownership, which he used not only to sustain a way of life, but also to develop Leamington, Warwickshire, into a spa town and pleasure resort.
The Neptune Islands Group and Western Kangaroo Island Marine Parks were declared as part of South Australia’s representative system of Marine protected areas (MPAs) in 2009. Sanctuary zones, located within these MPAs, prohibited commercial fishing in the state’s Northern Zone Rock Lobster Fishery from 2014. In 2022, dedicated surveys were undertaken both inside and outside two of the sanctuary zones to estimate the relative abundance (catch per unit effort; CPUE) and size of southern rock lobster (Jasus edwardsii). Survey results were then compared to estimates of abundance obtained from long-term commercial fishery-dependent data within each area. The legal-size CPUE by weight of lobsters was 389% and 411% higher inside sanctuary zones of the Neptune Islands Group and Western Kangaroo Island, respectively, compared to outside, based on survey data. Survey catch rates inside the two sanctuary zones were also considerably higher than historical catch rates estimated from commercial fishing data. Lobsters inside both sanctuary zones were larger than those outside in terms of mean weight compared to historical estimates. However, surveys recorded similar mean size in lobsters both inside and outside the Neptune Islands Group sanctuary zone, indicating a possible spillover effect of MPA protection. The Northern Zone Rock Lobster Fishery is currently in a biomass rebuilding phase. The results highlight the productivity potential of temperate reef ecosystems within South Australia in terms of southern rock lobster abundances.
Motivational Interviewing (MI) has demonstrated significant effects in diverse areas of practice, with over 2,000 controlled clinical trials published. Some criticisms of MI have emerged along the way.
Aims:
We examine theoretical and methodological critiques of MI.
Method:
We discuss three significant theoretical and methodological criticisms of MI: (1) that MI lacks conceptual stability; (2) that MI lacks a theoretical foundation; and (3) that MI is just common factors in psychotherapy.
Results:
It is true that definitions and descriptions of MI have evolved over the years. Mastery of MI clearly varies across providers, and when the quality of an intervention is unmeasured, it is unclear what has been trained or delivered. Reliable and valid tools to assess MI fidelity are available but often unused in outcome studies. It remains unclear what levels of proficiency are necessary to improve client outcomes. Some attempts to minimize variability in the delivery of MI appear to have reduced its effectiveness. In respect of the second critique is that MI lacks a theoretical foundation. It is unclear whether and how this is a disadvantage in research and practice. Various theories have been proposed and specific causal chain predictions have been tested. A third critique is that MI is merely common factors found among psychotherapists. The contribution of such relational skills is testable. There are specific aspects of MI related to client language that influence client outcomes above and beyond its relational components.
Conclusions:
The critiques reflect important factors to consider when delivering, training, and evaluating MI research.
In this work, we numerically investigate heat transfer in low-Prandtl-number drop-laden wall-bounded turbulence. These flows are characteristic of nuclear and fusion technologies, where liquid metals – known for their high thermal conductivity – are laden with drops or bubbles of another liquid or pressurised gas. To this end, we consider forced convection turbulence between two differentially heated parallel plates. The carrier phase (i.e. liquid metal) is characterised by a low Prandtl number $Pr_c=0.013$, while for the dispersed phase, we explore a range of Prandtl numbers from $Pr_d=0.013$ (matched case) to $Pr_d=7$ (super-unitary Prandtl number in the dispersed phase). Simulations are conducted at constant friction Reynolds number $Re_\tau =300$, and for each dispersed phase Prandtl number, two volume fractions are examined: $\alpha =5.4\,\%$ and $\alpha =10.6\,\%$. The simulation framework relies on direct numerical simulation of the Navier–Stokes equations, coupled with a phase-field method and the energy equation. Results show that an increase of the dispersed phase Prandtl number reduces heat transfer, leading to a lower Nusselt number for both volume fractions. To explain this behaviour, we analyse how the drops modify the temperature field, and demonstrate that the heat transfer reduction stems from a decreased diffusive heat flux within the dispersed phase. Finally, we propose a phenomenological model to predict the Nusselt number as a function of both the dispersed phase volume fraction and Prandtl number.
