Archaeological excavations conducted during the construction of the Museum of the Acropolis in Athens exposed an urban neighbourhood dated from the classical to the Byzantine periods. This discovery induced a modification of the original architectural plan: museum and excavation were combined into a unique exhibition ensemble. Its visitors further created another, peculiar and makeshift, spatial innovation in the excavation quarters. This study focuses upon multiple enacted receptions of historical spaces on the site, diachronically. Byzantine dwellers perceived and used the ancient site; the Museum creators integrated the Byzantine neighbourhood; contemporary visitors spontaneously signified the entire complex with new symbolic meaning.
The sulphur microbial diet (SMD), a dietary pattern associated with forty-three sulphur-metabolising bacteria, may influence gut microbiota composition and contribute to ageing process through gut-produced hydrogen sulfide (H2S). We aimed to explore the association between SMD and biological age (BA) acceleration, using the cross-sectional study that included 71 579 individuals from the UK Biobank. The SMD score was calculated by multiplying β-coefficients by corresponding serving sizes and summing them, based on dietary data collected using the Oxford WebQ, a 24-hour dietary assessment tool. BA was assessed using Klemerae–Doubal (KDM) and PhenoAge methods. The difference between BA and chronological age refers to the age acceleration (AgeAccel), termed ‘KDMAccel’ and ‘PhenoAgeAccel’. Generalised linear regression was performed. Mediation analyses were used to investigate underlying mediators including BMI and serum aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio. Following adjustment for multiple variables, a positive association was observed between consuming a dietary pattern with a higher SMD score and both KDMAccel (βQ4 v. Q1 = 0·35, 95 % CI = 0·27, 0·44, P < 0·001) and PhenoAgeAccel (βQ4 v. Q1 = 0·32, 95 % CI = 0·23, 0·41, P < 0·001). Each 1-SD increase in SMD score was positively associated with the acceleration of BA by 7·90 % for KDMAccel (P < 0·001) and 7·80 % for PhenoAgeAccel (P < 0·001). BMI and AST/ALT mediated the association. The stratified analysis revealed stronger accelerated ageing impacts in males and smokers. Our study indicated a higher SMD score is associated with elevated markers of biological ageing, supporting the potential utility of gut microbiota-targeted dietary interventions in attenuating the ageing process.
Instrumental tuition is by many seen as the cornerstone of higher music education (HME) performance programmes. An increasing body of research looks into its strengths and weaknesses and calls for development in a number of ways. This study contributes to this debate by exploring the ways in which international instrumental tuition practices are different, however limited to Western classical music practices. The article reports on a qualitative interview study of 12 students with experiences from 11 countries across America, Europe and Asia. Analysis of the interview data suggests that instrumental tuition practices are different when it comes to teacher positions, lesson formats and social organisation, responsibility and student voice and subject matter foci. These differences seem to correspond to social, musical and pedagogical structures and assumptions, and they could, as a result, be seen as differences on an international, institutional and individual level. The study suggests further that instrumental tuition practices could be seen as various manifestations of and negotiations between two broad archetypes in education: a teacher-centred archetype and a student-centred archetype. Increased knowledge about the variety of instrumental tuition practices is potentially a crucial matter in the field of HME, not the least due to power issues, and the study provides an analytical framework to analyse international, institutional and individual practices.
Although linked fate has been recognized as a driving force in the politics of various identity groups, should this theoretical framework be applied to queer politics? I ask, what are the outcomes and dynamics of linked fate among members of the queer community? How does linked fate shape queer political participation? Is the concept an adequate indicator of politicized queer identity? Drawing on data from the Collaborative Multiracial Post-Election Survey, I uncover widespread linked fate among queer Americans, with significant variation along the lines of intersectional identity. Linked fate can motivate participation, but more powerfully shapes participation beyond the ballot box. I close by calling for a queer-specific metric of linked fate that accounts for several dimensions of queer political identity. As the queer community grows increasingly salient in US party politics, this study identifies avenues for future research into this diverse population.
This work reports high-fidelity shock-tube experiments on the convergent Richtmyer–Meshkov (RM) instability at a heavy gas layer. The convergent shock tube is designed based on shock dynamics theory, significantly mitigating interface deceleration and reflected shock. As a result, long-term observation of instability growth up to nonlinear stage, free of interface deceleration and reshock, is achieved. Various types of SF$_6$ layers surrounded by air with controllable thicknesses and shapes, created using a soap film technique, are examined. For thick layers, the evolutions of the outer and inner interfaces are nearly decoupled regardless of the layer shape. The weakly nonlinear model of Wang (Phys. Plasmas,vol. 22, 2015, p. 082702), designed for cylindrical RM instability at a single interface, provides a reasonable prediction of perturbation growth at the inner interface, while slightly underestimating instability growth at the outer interface, as it neglects the effects of rarefaction wave. For thin layers, perturbation growth is fastest at either interface when both interfaces initially possess in-phase perturbations, moderate when only one interface is initially perturbed and slowest when the two interfaces have anti-phase perturbations. This variation in growth rates is due to the fact that the evolution of a thin layer is influenced by both reverberating waves and interface coupling, with each factor being highly sensitive to the layer shape. The original vortex method is extended to address the convergent RM instability by incorporating the influences of unsteady background flow, interface coupling and reverberating waves into the transport of a vortex sheet. This extended vortex method enables accurate prediction of convergent RM instability at a gas layer, covering the full range from early linear to late nonlinear stages.
The medieval Slavs approached Byzantine speculative thought with caution. This essay explores Slavic hesitancy towards Greek theoretical ambition within the writings on visions of the Bulgarian theologian Euthymios of Tarnovo. Whereas the Greek hesychast theologian Gregory Palamas argued that the saints behold God's glory without mediation, Euthymios took a more modest approach, asserting that angels arbitrate between heaven and earth and bestow visions on the saints. Earlier scholars have described Euthymios as a ‘hesychast’, yet his views on visions align more closely with Palamas’ opponents and the Corpus of Pseudo-Dionysios.
Mothers living in low-income families are more likely to experience depressive symptoms and parenting stress which in turn can undermine mother–child interactions adversely influencing child outcomes. Previous studies demonstrate that social support is beneficial for low-income mothers to fulfill caregiving responsibilities and promote positive child outcomes. However, the longitudinal application of the Family Stress Model with protective factors remains unexplored in the literature. Thus, we examined the association between parenting stress and depressive symptoms at year 1 with harsh and responsive parenting at year 3. Then, we examined whether parenting practices at year 3 predicted child outcomes at year 5 and the main and moderating effects of social support at year 1 and year 3 on parenting and child outcomes. The sample included 1,968 mothers from the Future of Families and Child Wellbeing Study. Results showed that parenting stress significantly predicted harsh parenting. Harsh parenting was associated with more internalizing behavior problems and decreased adaptive social behavior. Responsive parenting was associated only with fewer internalizing behavior problems. The main effects of social support on responsive and harsh parenting and child outcomes were significant. Specific intervention programs targeted at reducing parenting stress, enhancing parenting skills, and improving the social support network should be designed to support mothers in the context of economic adversity.
This essay considers the “great” status of Shah ‘Abbās I, the most consequential Safavid ruler, by comparing European descriptions to his portrayal in the Persian-language sources. While both depict him as energetic, resolute, and unadorned in attire and demeanor, European sources present him primarily as an empire builder while Persian-language works focus on his role as a warrior on horseback, fighting external enemies and putting down domestic revolts. Neither accounts ignore the violence that came with absolute power, but while Europeans viewed such violence as an unfortunate byproduct of power, Persian chronicles celebrate ‘Abbās as a ghāzi warrior, merciless in his efforts to root out heretics and unbelievers. The surviving image of the shah as a “great” ruler was first reported by European visitors and is primarily a composite of the way they depicted him – as a Renaissance prince and determined empire builder who remained close to his subjects and their concerns.
Governments offer resource user rights, such as individual and collective agricultural land rights, fishing quotas, and territorial user rights in marine activities, to induce economic development and efficient resource use. Yet, user rights and improved incomes do not always lead to project uptake, as in rural-rural migration. Marine user rights may differ from land tenure rights, especially when rights are individual or collective. We explore household survey data from Chile about participation in projects linking marine resource activities with user rights across payoff levels and commute/relocation ‘disruption’ costs. Households are more likely to participate in projects with low disruption costs and high incomes, yet many households reject lucrative projects. The household's existing user rights and the project's activity–rights pairs affect project participation levels, with differences across collective and individually-held rights. These results inform policy aimed at increasing incomes and resource use efficiency through marine resource projects with user rights.
Generative artificial intelligence (AI) systems, notably ChatGPT, have emerged in legal practice, facilitating the completion of tasks, ranging from electronic communications to the drafting of documents. The generative capabilities of these systems underscore the duty of lawyers to competently represent their clients by keeping abreast of technological developments that can enhance the efficiency and effectiveness of their work. At the same time, the processing of clients’ information through generative AI systems threatens to compromise their confidentiality if disclosed to third parties, including the systems’ providers. The present paper aims to determine the impact of the use of generative AI systems by lawyers on the duties of competence and confidentiality. The findings derive from the application of doctrinal and empirical research on the legal practice and its digitalisation in Luxembourg. The paper finally reflects on the integration of generative AI systems in legal practice to raise the quality of legal services for clients.
This study aimed to assess vaping prevalence, motivations and risk perceptions among adults attending ENT clinics in the East of England.
Methods
A survey was conducted with 284 adults (aged ≥18), gathering data on demographics, vaping habits, awareness of health risks and attitudes towards regulation.
Results
A total of 24 per cent reported vaping, particularly among those aged 18–25 years and the unemployed (p = 0.027). The main motivation was smoking cessation (49 per cent), followed by stress relief and social factors. Vapers perceived vaping as less harmful, while 60 per cent of non-vapers considered it “very harmful.” Awareness of risks was low, especially among younger adults and the unemployed, with 83 per cent lacking sufficient information. Non-vapers (84 per cent) supported stricter regulations.
Conclusion
Vaping is currently a poorly defined health risk. There is a need for targeted education on vaping risks and enhanced regulation, particularly within ENT settings. Further research is required to explore vaping’s health impacts on ENT health.
The complex tasks of air traffic control (ATC) and the various factors affecting its operation have shed light on the need to build a model to predict conflict detection and resolution (CDR) performance within a traffic situation. This study aimed at developing a fuzzy-hybrid framework for quantifying various aspects in ATC consisting of the software, hardware, environment, liveware and organisation (i.e. the SHELL model) to predict CDR performance. The proposed fuzzy-hybrid SHELL framework in this study was tested using metadata from 10 prior studies in ATC. The results showed a highly accurate prediction, as indicated by the RMSE and MAPE values of 0⋅09 and 5⋅36%, respectively, indicating a high consistency of 90⋅92% for predicting the CDR performance. This framework offers a promising approach for Air Navigation Service Providers (ANSPs) to maintain air traffic safety and improve ATC operations efficiency.
This study aimed to assess whether frailty (measured using the 5-Item Modified Frailty Index) was associated with increased morbidity following surgical tracheostomy.
Methods
A single-centre retrospective cohort study analysed a prospectively maintained database between 2022 and 2023. Univariable and multivariable regressions were used to determine factors (including frailty) associated with increased morbidity.
Results
A total of 174 patients underwent surgical tracheostomy in the study period with 28 patients determined as frail (16.1 per cent). Overall, 21 patients (12.1 per cent) suffered a tracheostomy-specific complication. Multivariable regression found an association between frail patient status and increased tracheostomy-specific complications (odds ratio 4.09, 95 per cent confidence interval 1.51–11.11; p = 0.006) and longer hospital length of stay (β 15.76 days, 95 per cent confidence interval 1.06–30.44; p = 0.036).
Conclusion
Frailty was associated with increased morbidity and longer hospital stay following tracheostomy. Assessment of frailty may guide decision making and patient discussions when planning tracheostomy.
We establish Trudinger-type inequalities for variable Riesz potentials $J_{\alpha (\cdot ), \tau }f$ of functions in Musielak–Orlicz spaces $L^{\Phi }(X)$ over bounded metric measure spaces X equipped with lower Ahlfors $Q(x)$-regular measures under conditions on $\Phi $ which are weaker than conditions in the previous paper (Houston J. Math. 48 (2022), no. 3, 479–497). We also deal with the case $\Phi $ is the double phase functional with variable exponents. As an application, Trudinger-type inequalities are discussed for Sobolev functions.
In the late 1920s and the 1930s a fully developed discourse emerged in China that linked either travel as a general concept (mostly with a primary focus on its leisure form) or tourism more specifically to the interests of society and the nation. This article analyses its development as it evolved in the first half of the twentieth century. For this purpose, it first probes into the discourse that surrounded, from the 1920s onwards, the constitution and the activity of the Travel Department of the Shanghai Commercial and Savings Bank and of the China Travel Service, in line with which the travel service that one and the other provided was considered to involve dimensions of service to the nation and to society. The article proceeds by looking into two separate but ultimately linked lines of discourse that came to full bloom during the Nanjing decade and after: one that linked travel to the building of society, and another that linked it to the strengthening of the nation.
In this overview of the dynamic field of MG sociolinguistics in the last four decades, we show the decisive move of the field, in the spirit of sociolinguistics in general, toward permeable boundaries with other areas of linguistics that set out to investigate language-as-action and language-in-context, as well as toward synergies with other disciplines invested in the study of society and culture. The studies we discuss show how researchers have been documenting a changing, diverse society, considering different resources and environments where language is used, and with a growing focus on digital media. These studies also reflect a shift towards sociolinguistic research that addresses social justice issues and recent socio-political crises in Greek society.
This article investigates indigenous light as an element in the conceptualization of photography as a ‘Greek’ art from the mid-nineteenth to the first decades of the twentieth century. Key moments linking photography, writing through light, with the light of Greece will be discussed: from the mid-nineteenth-century debate about the alleged ‘Greek’ origins of photography to the thematization of light and gazing at the Greek landscape in the writings of Periklis Yannopoulos and, eventually, to interwar photographic projects bringing together contemporary scenery with antique material relics.
