This article presents a systematic literature review of publications from 2014 to 2021 using “archaeological site” and “climate change” as keywords, in addition to several terms representing forms of stakeholder engagement. Articles were thematically coded to explore trends at the intersection of climate change, archaeology, and local and Traditional stakeholders. Results show that nearly half of the selected publications did not include local and Traditional stakeholder engagement in studies related to climate adaptation planning for archaeological sites. Synthesis of the results with insights gained from other literature on decolonizing archaeology showed that potential reasons for this gap include (1) the academic publishing culture, (2) archaeology as a predominantly Western discipline, and (3) increasingly available tools for climate change adaptation planning for archaeological sites. This article calls on the academic community to consider holistic stewardship using a landscape approach and to use climate change adaptation planning to elevate local and Traditional stakeholder input and values.
This article conducts an exploratory multidimensional (MD) analysis of four interactive online registers, namely newspaper comments, tweets, web forums and text messages, originating from four South Asian countries (Bangladesh, India, Pakistan and Sri Lanka) and two Inner Circle (Kachru 1985) English-speaking countries (UK and USA). A principal component analysis (PCA) has been performed on the interactive registers using linguistic features tagged by a modified version of the MFTE tagger (Le Foll 2021a). The dimensions resulting from the PCA show that nominal, literate and informational features are generally more common in the South Asian data – which represent varieties belonging to the Outer Circle (Kachru 1985). Additionally, different features are used for expressing persuasion or opinion compared to the two reference varieties.
We systematically study calibrated geometry in hyperkähler cones $C^{4n+4}$, their 3-Sasakian links $M^{4n+3}$, and the corresponding twistor spaces $Z^{4n+2}$, emphasizing the relationships between submanifold geometries in various spaces. Our analysis highlights the role played by a canonical $\mathrm {Sp}(n)\mathrm {U}(1)$-structure $\gamma $ on the twistor space Z. We observe that $\mathrm {Re}(e^{- i \theta } \gamma )$ is an $S^1$-family of semi-calibrations and make a detailed study of their associated calibrated geometries. As an application, we obtain new characterizations of complex Lagrangian and complex isotropic cones in hyperkähler cones, generalizing a result of Ejiri–Tsukada. We also generalize a theorem of Storm on submanifolds of twistor spaces that are Lagrangian with respect to both the Kähler–Einstein and nearly Kähler structures.
A new model of the steady boundary layer flow around a rotating sphere is developed that includes the widely observed collision and subsequent eruption of boundary layers at the equator. This is derived following the Segalini & Garrett (J. Fluid Mech., vol. 818, 2017, pp. 288–318) asymptotic approach for large Reynolds numbers but replacing the Smith & Duck (Q. J. Mech. Appl. Maths, vol. 30, issue 2, 1977, pp. 143–156) correction with a higher-order version of the Stewartson (Grenzschichtforschung/Boundary Layer Research, 1958, pp. 59–71. Springer) model of the equatorial flow. The Stewartson model is then numerically solved, for the first time, via a geometric multigrid method that solves the steady planar Navier–Stokes equations in streamfunction-vorticity form on large rectangular domains in a quick and efficient manner. The results are then compared with a direct numerical simulation of the full unsteady problem using the Semtex software package where it is found that there is broad qualitative agreement, namely the separation and reattachment of the boundary layer at the equator. However, the presence of unobserved behaviour such as a large area of reverse flow seen at lower Reynolds numbers than those observed in other studies, and that the absolute error increases with Reynolds number suggest the model needs improvement to better capture the physical dynamics.
Globally, we are currently facing a rapid demographic shift leading to an increase in the proportion of older adults within the population. This raises concerns about the potential increase in age-related diseases and their impact on our ability to provide adequate health and end-of-life care. To apply appropriate interventions, understanding the changes that happen with ageing becomes essential. Ageing is often accompanied by a decrease in appetite and physical activity, which may lead to malnutrition, resulting in decreased muscle mass, physical capabilities and independence. To preserve muscle mass, older adults are advised to increase protein intake and physical activity. However, protein’s high satiating effect may cause reduced energy intake. Physical activity is also advised to maintain or enhance older adult’s appetite. This review paper aims to discuss appetite-related changes that occur with ageing and their consequences. In particular, it will focus on investigating the relationship between protein intake and physical activity and their impact on appetite and energy intake in the ageing population. Recent studies suggest that physical activity might contribute to maintaining or enhancing appetite in older adults. Nevertheless, establishing a definitive consensus on the satiating effect of protein in ageing remains a work in progress, despite some promising results in the existing literature.
This article focuses on how the policy on same-sex marriage and a person’s social locations impact upon Chinese lesbians’ life chances and welfare. Bringing the familisation and defamilisation literature, which has predominantly focused on heterosexual populations and families, into dialogue with an intersectionality perspective, we map the ways in which gender, sexuality, and class intersect in shaping lesbians’ experiences of defamilisation and familisation risks. The findings, drawn from interviews conducted in Beijing, China, reveal that the absence of legalised same-sex marriage, coupled with a lack of familial and societal recognition of same-sex relationships, exposes lesbians to both defamilisation and familisation risks, leading to difficulties in choosing whether and how to participate in the family. The intersectionality lens guides us to move beyond the heterosexual/homosexual boundary and to rethink the possibility of welfare alliances that can improve the welfare of not only lesbians but also other groups of women and minorities.
