    AbstractWe consider a fractional Adams method for solving the nonlinear fractional differential equation 0CDtαy(t)=f(t,y(t)),α>0, equipped with the initial conditions y(k)(0)=y0(k),k=0,1,…,⌈α⌉−1. Here, α may be an arbitrary positive number and ⌈α⌉ denotes the smallest integer no less than α and the differential operator is the Caputo derivative. Under the assumption 0CDtαy∈C2[0,T], Diethelm et al. (Numer. Algor. 36, 31–52, 2004) introduced a fractional Adams method with the uniform meshes tn = T(n/N),n = 0,1,2,…,N and proved that this method has the optimal convergence order uniformly in tn, that is O(N−2) if α > 1 and O(N−1−α) if α ≤ 1. They also showed that if 0CDtαy(t)∉C2[0,T], the optimal convergence order of this method cannot be obtained with the uniform meshes. However, it is well-known that for y ∈ Cm[0,T] for some m∈ℕ and 0 < α < m, the Caputo fractional derivative 0CDtαy(t) takes the form “0CDtαy(t)=ct⌈α⌉−α+smoother terms” (Diethelm et al. Numer. Algor. 36, 31–52, 2004), which implies that 0CDtαy behaves as t⌈α⌉−α which is not in C2[0,T]. By using the graded meshes tn = T(n/N)r,n = 0,1,2,…,N with some suitable r > 1, we show that the optimal convergence order of this method can be recovered uniformly in tn even if 0CDtαy behaves as tσ,0 < σ < 1. Numerical examples are given to show that the numerical results are consistent with the theoretical results.

  • Being Mesolithic in Life and Death

    Cobb, Hannah; email: hannah.cobb@manchester.ac.uk; Gray Jones, Amy; orcid: 0000-0002-1740-4621; email: a.grayjones@chester.ac.uk (Springer US, 2018-08-25)
    Abstract Fifty years ago, approaches to Mesolithic identity were limited to ideas of ‘Man the Hunter’ and ‘Woman the Gatherer’, while evidence of non-normative practice was ascribed to ‘shamans’ and to ‘ritual’, and that was that. As post-processual critiques have touched Mesolithic studies, however, this has changed. In the first decade of the 21st century a strong body of work on Mesolithic identity in life, as well as death, has enabled us to think beyond modern Western categories to interpret identity in the Mesolithic. These studies have addressed the nature of personhood and relational identities, the body, and the relationship between human and other-than-human persons. Our paper reviews these changing approaches, offering a series of case studies from a range of different sites that illustrate how identity is formed and transformed through engagements with landscapes, materials, and both living and dead persons. These are then developed to advocate an assemblage approach to identity in the Mesolithic.
  • Humans in the Environment: Plants, Animals and Landscapes in Mesolithic Britain and Ireland

    Overton, Nick J.; email: nicholas.overton@manchester.ac.uk; Taylor, Barry; email: b.taylor@chester.ac.uk (Springer US, 2018-05-29)
    AbstractEnvironmental archaeology has historically been central to Mesolithic studies in Britain and Ireland. Whilst processual archaeology was concerned with the economic significance of the environment, post-processual archaeology later rejected economically driven narratives, resulting in a turn away from plant and animal remains. Post-processual narratives focused instead on enigmatic ‘ritual’ items that economic accounts struggled to suitably explain. Processual accounts of landscapes, grounded in economic determinism, were also rejected in favour of explorations of their sociocultural aspects. However, in moving away from plant and animal remains, such accounts lacked the ability to rigorously explore the specificities of particular landscapes and humans actions within them. This paper will bridge this gap by considering how palaeoecological and zooarchaeological analyses can be used to explore human interactions with plants and animals, which were key in developing understandings and relationships that ultimately structured landscapes, influenced past human actions and shaped archaeological assemblages.
  • The Efficacy of Energy-Restricted Diets in Achieving Preoperative Weight Loss for Bariatric Patients: a Systematic Review.

    Naseer, Fathimath; Shabbir, Asim; Livingstone, Barbara; Price, Ruth; Syn, Nicholas L; Flannery, Orla; orcid: 0000-0002-4669-2781; email: O.flannery@chester.ac.uk (2018-08-18)
    In bariatric practice, a preoperative weight loss of at least 5% is recommended. However, the hypocaloric diets prescribed vary and no consensus exists. This study examined the efficacy of preoperative diets in achieving 5% weight loss. From a systematic literature search, eight randomised controlled trials (n = 862) were identified. Half of the trials used a "very-low-calorie diet" whilst the rest employed a "low-calorie diet". Only five diets achieved ≥ 5% weight loss over varying durations and energy intakes. By inference, compliance with a 700-1050 kcal (2929-4393 kJ) diet, consisting of moderate carbohydrate, high protein and low/moderate fat, for 3 weeks is likely to achieve 5% weight loss. A low-carbohydrate diet (< 20 g/day) may achieve this target within a shorter duration. Additional research is required to validate these conclusions.
  • Sleep duration and psychotic experiences in patients at risk of psychosis: A secondary analysis of the EDIE-2 trial.

    Reeve, S; email: sarah.reeve@psych.ox.ac.uk; Nickless, A; Sheaves, B; Hodgekins, J; Stewart, S L K; Gumley, A; Fowler, D; Morrison, A; Freeman, D (2018-08-16)
    Sleep disturbance is common among individuals at risk of psychosis, yet few studies have investigated the relationship between sleep disturbance and clinical trajectory. The Early Detection and Intervention Evaluation (EDIE-2) trial provides longitudinal data on sleep duration and individual psychotic experiences from a cohort of individuals at risk of psychosis, which this study utilises in an opportunistic secondary analysis. Shorter and more variable sleep was hypothesised to be associated with more severe psychotic experiences and lower psychological wellbeing. Mixed effect models were used to test sleep duration and range as predictors of individual psychotic experiences and psychological wellbeing over the 12-24 months (with assessments every 3 months) in 160 participants. Shorter sleep duration was associated with more severe delusional ideas and hallucinations cross-sectionally and longitudinally. The longitudinal relationships did not remain significant after conservative controls were added for the previous severity of psychotic experiences. No significant relationships were found between the sleep variables and other psychotic experiences (e.g. cognitive disorganisation), or psychological wellbeing. The results support a relationship between shorter sleep duration and delusional ideas and hallucinations. Future studies should focus on improving sleep disturbance measurement, and test whether treating sleep improves clinical trajectory in the at-risk group.

  • What is the effect of aerobic exercise intensity on cardiorespiratory fitness in those undergoing cardiac rehabilitation? A systematic review with meta-analysis.

    Assess the role of exercise intensity on changes in cardiorespiratory fitness (CRF) in patients with cardiac conditions attending exercise-based cardiac rehabilitation. Systematic review with meta-analysis. MEDLINE, Embase, CINAHL, SPORTDiscus, PsycINFO and Web of Science. Studies assessing change in CRF (reported as peak oxygen uptake; V̇O ) in patients post myocardial infarction and revascularisation, following exercise-based cardiac rehabilitation. Studies establishing V̇O via symptom-limited exercise test with ventilatory gas analysis and reported intensity of exercise during rehabilitation were included. Studies with mean ejection fraction <40% were excluded. 128 studies including 13 220 patients were included. Interventions were classified as moderate, moderate-to-vigorous or vigorous intensity based on published recommendations. Moderate and moderate-to-vigorous-intensity interventions were associated with a moderate increase in V̇O (standardised mean difference±95% CI=0.94±0.30 and 0.93±0.17, respectively), and vigorous-intensity exercise with a large increase (1.10±0.25). Moderate and vigorous-intensity interventions were associated with moderate improvements in V̇O (0.63±0.34 and 0.93±0.20, respectively), whereas moderate-to-vigorous-intensity interventions elicited a large effect (1.27±0.75). Large heterogeneity among studies was observed for all analyses. Subgroup analyses yielded statistically significant, but inconsistent, improvements in CRF. Engagement in exercise-based cardiac rehabilitation was associated with significant improvements in both absolute and relative V̇O . Although exercise of vigorous intensity produced the greatest pooled effect for change in relative V̇O , differences in pooled effects between intensities could not be considered clinically meaningful.

  • Patients' Perspectives of Oral and Injectable Type 2 Diabetes Medicines, Their Body Weight and Medicine-Taking Behavior in the UK: A Systematic Review and Meta-Ethnography.

    Psarou, Aikaterini; orcid: 0000-0002-0447-4452; email: kpsarou@yahoo.co.uk; Cooper, Helen; Wilding, John P H (2018-08-17)
    The aim of this review is to identify peoples' perspectives of their glucose-lowering and anti-obesity drugs in relation to diabetes and weight control and to explore how these views affect medication adherence. Theoretical perspectives associated with medicine-taking behavior are also explored. The systematic review was based on a meta-ethnography of qualitative studies identified through a search of 12 medical and social science databases and subsequent citation searches. The quality of all studies was assessed. Sixteen studies were included with data from 360 UK individuals. No relevant studies were identified which focused on anti-obesity and non-insulin injectable drugs. The review revealed that the patients' perspectives and emotional state were influenced by starting and/or changing to a new glucose-lowering medicine. These were also influenced by prior medication experience, disease perceptions and interactions with clinicians. Despite reports of positive experiences with and positive perceptions of medicines, and of participation in strategies to regain life control, medication non-adherence was common. Accepting glucose-lowering medicines impacted on the individual's perception of lifestyle changes, and it was notable that weight loss was not perceived as a strategy to support diabetes management. Synthesis revealed that more than one theory is required to explain medicine-taking behavior. New insights into the underlying factors of poor adherence and the specific practical issues identified in this review can help in the development of patient-centered interventions. Diabetes UK.
