Brexit and UK international development policy
In this article we explore the implications of Brexit for the UK and the EU's development policies and strategic directions, focusing on the former. While it is likely that the operational process of disentangling the UK from the various development institutions of the EU will be relatively straightforward, the choices that lie ahead about whether and how to cooperate thereafter are more complex. Aid and development policy touches on a wide range of interests—security, trade, climate change, migration, gender rights, and so on. We argue that Brexit will accelerate existing trends within UK development policy, notably towards the growing priority of private sector-led economic growth strategies and blended finance tools. There are strong signals that UK aid will be cut, as successive secretaries of state appear unable to persuade a substantial section of the public and media that UK aid and development policy serves UK interests in a variety of ways
On the Use of Biomineral Oxygen Isotope Data to Identify Human Migrants in the Archaeological Record: Intra-Sample Variation, Statistical Methods and Geographical Considerations.
Oxygen isotope analysis of archaeological skeletal remains is an increasingly popular tool to study past human migrations. It is based on the assumption that human body chemistry preserves the δ18O of precipitation in such a way as to be a useful technique for identifying migrants and, potentially, their homelands. In this study, the first such global survey, we draw on published human tooth enamel and bone bioapatite data to explore the validity of using oxygen isotope analyses to identify migrants in the archaeological record. We use human δ18O results to show that there are large variations in human oxygen isotope values within a population sample. This may relate to physiological factors influencing the preservation of the primary isotope signal, or due to human activities (such as brewing, boiling, stewing, differential access to water sources and so on) causing variation in ingested water and food isotope values. We compare the number of outliers identified using various statistical methods. We determine that the most appropriate method for identifying migrants is dependent on the data but is likely to be the IQR or median absolute deviation from the median under most archaeological circumstances. Finally, through a spatial assessment of the dataset, we show that the degree of overlap in human isotope values from different locations across Europe is such that identifying individuals' homelands on the basis of oxygen isotope analysis alone is not possible for the regions analysed to date. Oxygen isotope analysis is a valid method for identifying first-generation migrants from an archaeological site when used appropriately, however it is difficult to identify migrants using statistical methods for a sample size of less than c. 25 individuals. In the absence of local previous analyses, each sample should be treated as an individual dataset and statistical techniques can be used to identify migrants, but in most cases pinpointing a specific homeland should not be attempted
Report of the household survey: La Ronge, SK
Mounting concerns about individual and community preparedness for disasters are being voiced, in part because natural disasters are increasing. In Canada, circumstances such as pine beetle infestations, reduced precipitation coupled with above normal tem-peratures, and an increased number of homes in forested areas contribute to the in-creased occurrence of wildfires and their impact on humans. In order to understand community responses to wildfires, a mixed method study was conducted (2008-2010) in two communities in western Canada: Barriere, British Columbia and La Ronge, Sas-katchewan (ruralwildfire.ca). These two communities were selected since they had en-dured wildfires that resulted in community evacuation with significant loss of property (McClure fire in BC, 2003; and, Mallard fire in SK, 1999)
Report of the household survey: Coaldale, AB
There are mounting concerns about individual and community preparedness for disasters in part because disasters are increasing in numbers. Circumstances such as pine beetle infestations, climate change and an increased number of homes in forested areas contribute to the increased number of disasters and their impacts. In order to understand community response to wildfires, a mixed method study was conducted (2008-2010) in two communities in western Canada (Barriere, British Columbia and La Ronge, Saskatchewan) (ruralwildfire.ca). These two communities were selected since they had endured wildfires that resulted in community evacuation with significant loss of property (McClure fire in BC, 2003; and, Mallard fire in SK, in 1999). Coaldale, Alberta was chosen as a comparison community that had not experienced a recent natural disaster and was of similar size to Barriere and La Ronge
Sea, sickness and cautionary tales: a multi-isotope study from a post-mediaeval hospital at the city-port of Gibraltar (AD 1462–1704)
Abstract: During the sixteenth to eighteenth centuries, Spanish ships sailed around the globe connecting Spain to its colonies. While documentary records offer rich details concerning life on board ship, archaeological information is essential to generating a full picture of the past. The cemetery at Old St Bernard’s Hospital, Gibraltar, provides an opportunity to study the skeletal remains of sailors. Following previous osteological research, carbon, nitrogen, oxygen and strontium isotope analyses were undertaken on thirty-three of these individuals. The results show that the, largely male, individuals had various different diets during life and came from several different places. Diets were largely based on C3 food chains; some individuals consumed C3 foods with low δ13C values; others consumed some marine foods, and a few individuals had a high trophic level diet, through the consumption of either freshwater resources or a high proportion of animal protein. The individuals spent their childhoods in several different places, although these homelands do not correlate simply with dietary variation. This variety in diets and homelands is consistent with our expectations for this hospital site given its location in a post-mediaeval entrepôt. The interpretation of these results are greatly helped by the available historical information and this has broader implications for the interpretation of isotope data elsewhere where the historical context of the site and the mobility patterns of the individuals are less well known

Carbon and Nitrogen Isotopic Variability in Foxtail Millet
RATIONALE: Isotopic palaeodietary studies generally focus on bone collagen from human and/or animal remains. While plant remains are rarely analysed, it is known that plant isotope values can vary as a result of numerous factors, including soil conditions, the environment and type of plant. The millets were important food crops in prehistoric Eurasia, yet little is known about the isotopic differences within millet species. METHODS: Here we compare the stable isotope ratios within and between Setaria italica plants grown in a controlled environment chamber. Using homogenised samples, we compare carbon isotope ratios of leaves and grains, and nitrogen isotope ratios of grains, from 29 accessions of Setaria italica. RESULTS: We find significant isotopic variability within single leaves and panicles, and between leaves and panicles within the same plant, which must be considered when undertaking plant isotope studies. We find that the leaves and grains from the different accessions have a ca 2‰ range in δ(13) C values, while the nitrogen isotope values in the grains have a ca 6‰ range. We also find an average offset of 0.9‰ between leaves and grains in their δ(13) C values. CONCLUSIONS: The variation found is large enough to have archaeological implications and within- and between-plant isotope variability should be considered in isotope studies. The range in δ(15) N values is particularly significant as it is larger than the typical values quoted for a trophic level enrichment, and as such may lead to erroneous interpretations of the amount of animal protein in human or animal diets. It is therefore necessary to account for the variability in plant stable isotope values during palaeodietary reconstructions.

Localized management of non-indigenous animal domesticates in Northwestern China during the Bronze Age.
The movements of ancient crop and animal domesticates across prehistoric Eurasia are well-documented in the archaeological record. What is less well understood are the precise mechanisms that farmers and herders employed to incorporate newly introduced domesticates into their long-standing husbandry and culinary traditions. This paper presents stable isotope values (δ13C, δ15N) of humans, animals, and a small number of plants from the Hexi Corridor, a key region that facilitated the movement of ancient crops between Central and East Asia. The data show that the role of animal products in human diets was more significant than previously thought. In addition, the diets of domestic herbivores (sheep/goat, and cattle) suggest that these two groups of domesticates were managed in distinct ways in the two main ecozones of the Hexi Corridor: the drier Northwestern region and the wetter Southeastern region. Whereas sheep and goat diets are consistent with consumption of naturally available vegetation, cattle exhibit a higher input of C4 plants in places where these plants contributed little to the natural vegetation. This suggests that cattle consumed diets that were more influenced by human provisioning, and may therefore have been reared closer to the human settlements, than sheep and goats
Achieving consensus on psychosocial and physical rehabilitation management for people living with kidney disease
From Crossref journal articles via Jisc Publications RouterHistory: epub 2023-05-19, issued 2023-05-19Article version: AMPublication status: PublishedPelagia Koufaki - ORCID: 0000-0002-1406-3729
https://orcid.org/0000-0002-1406-3729Background People living with chronic kidney disease (CKD) need to be able to live well with their condition. The provision of psychosocial interventions (psychological, psychiatric, and social care) and physical rehabilitation management is variable across England, as well as the rest of the United Kingdom. There is a need for clear recommendations for standards of psychosocial and physical rehabilitation care for people living with CKD, and guidance for the commissioning and measurement of these services. The NHS England Renal Services Transformation Programme (RSTP) supported a programme of work and modified Delphi process to address the management of psychosocial and physical rehabilitation care as part of a larger body of work to formulate a comprehensive commissioning toolkit for renal care services across England. We sought to achieve expert consensus regarding the psychosocial and physical rehabilitation management of people living with CKD in England and the rest of the UK. Method A Delphi consensus method was used to gather and refine expert opinions of senior members of the kidney multi-disciplinary team (MDT) and other key stakeholders in the UK. An agreement was sought on 16 statements reflecting aspects of psychosocial and physical rehabilitation management for people living with CKD. Results Twenty-six expert practitioners and other key stakeholders, including lived experience representatives, participated in the process. The consensus (>80% affirmative votes) amongst the respondents for all 16 statements was high. Nine recommendation statements were discussed and refined further to be included in the final iteration of the ‘Systems’ section of the NHS England RSTP commissioning toolkit. These priority recommendations reflect pragmatic solutions that can be implemented in renal care and include recommendations for a holistic well-being assessment for all people living with CKD who are approaching dialysis, or who are at listing for kidney transplantation, which includes the use of validated measurement tools to assess the need for further intervention in psychosocial and physical rehabilitation management. It is recommended that the scores from these measurement tools be included in the NHS England Renal Data Dashboard. There was also a recommendation for referral as appropriate to NHS Talking therapies, psychology, counselling or psychotherapy, social work or liaison psychiatry for those with identified psychosocial needs. The use of digital resources was recommended to be used in addition to face-to-face care to provide physical rehabilitation, and all healthcare professionals should be educated to recognise psychosocial and physical rehabilitation needs and refer/sign-post people with CKD to appropriate services. Conclusion There was high consensus amongst senior members of the kidney MDT and other key stakeholders, including those with lived experience, in the UK on all aspects of the psychosocial and physical rehabilitation management of people living with CKD. The results of this process will be used by NHS England to inform the ‘Systems’ section of the commissioning toolkit and data dashboard and to inform the National Standards of Care for people living with CKD.inpressinpres
