The RESET project: constructing a European tephra lattice for refined synchronisation of environmental and archaeological events during the last c. 100 ka

This paper introduces the aims and scope of the RESET project (. RESponse of humans to abrupt Environmental Transitions), a programme of research funded by the Natural Environment Research Council (UK) between 2008 and 2013; it also provides the context and rationale for papers included in a special volume of Quaternary Science Reviews that report some of the project's findings. RESET examined the chronological and correlation methods employed to establish causal links between the timing of abrupt environmental transitions (AETs) on the one hand, and of human dispersal and development on the other, with a focus on the Middle and Upper Palaeolithic periods. The period of interest is the Last Glacial cycle and the early Holocene (c. 100-8 ka), during which time a number of pronounced AETs occurred. A long-running topic of debate is the degree to which human history in Europe and the Mediterranean region during the Palaeolithic was shaped by these AETs, but this has proved difficult to assess because of poor dating control. In an attempt to move the science forward, RESET examined the potential that tephra isochrons, and in particular non-visible ash layers (cryptotephras), might offer for synchronising palaeo-records with a greater degree of finesse. New tephrostratigraphical data generated by the project augment previously-established tephra frameworks for the region, and underpin a more evolved tephra 'lattice' that links palaeo-records between Greenland, the European mainland, sub-marine sequences in the Mediterranean and North Africa. The paper also outlines the significance of other contributions to this special volume: collectively, these illustrate how the lattice was constructed, how it links with cognate tephra research in Europe and elsewhere, and how the evidence of tephra isochrons is beginning to challenge long-held views about the impacts of environmental change on humans during the Palaeolithic. © 2015 Elsevier Ltd.RESET was funded through Consortium Grants awarded by the Natural Environment Research Council, UK, to a collaborating team drawn from four institutions: Royal Holloway University of London (grant reference NE/E015905/1), the Natural History Museum, London (NE/E015913/1), Oxford University (NE/E015670/1) and the University of Southampton, including the National Oceanography Centre (NE/01531X/1).

They provided excellent advice at key stages of the work, which we greatly valued.

Cytomorphometry of serosal effusion in dogs

Cytomorphometry made on cytological slides is the quantitative method of precise analysis of cellular structures, including both cytoplasm and nucleus. The aim of this study was to describe cytomorphometric parameters of mesothelial cells in the course of benign reactive and malignant proliferation and to compare them to carcinomas and adenocarcinomas located within serosal cavities in dogs. The second aim was to evaluate applicability of cytomorphometry to diagnostics of diseases causing accumulation of effusion in serosal cavities. Cytological samples of normal and non-malignant mesothelium, mesothelioma and various carcinomas were collected from dogs. Cytomorphometry was made on the smears stained with Giemsa solution. Mean nuclear and cellular perimeter, mean nuclear and cellular area, mean nuclear and cellular diameter, and mean nuclear and cellular roundness were determined. Moreover, nuclear to cytoplasmic ratio (N/C) was calculated. The data revealed statistically significant differences for all parameters, excluding mean nuclear perimeter, between compared groups. Normal mesothelium cells and their nuclei were significantly smaller and more elongated than cells and nuclei of both benign reactive and malignant neoplastic mesothelium. Only a few differences were observed between benign reactive mesothelium cells and mesothelioma cells – mean nuclear area and mean nuclear diameter of benign reactive mesothelium cells were significantly larger and N/C ratio was higher in comparison to mesothelioma cells. Even though some significant differences were observed, considerable overlap of these cytomorphometric parameters in animals with different diseases limited practical role of these observations. Cytomorphometric analysis of cellular samples collected from dogs with proliferative processes affecting serosal cavities can be only an auxiliary method increasing accuracy of preoperative diagnosis

An e-health strategy to facilitate care of breast cancer survivors : a pilot study

Aim: Innovative e-health strategies are emerging, to tailor and provide convenient, systematic and high quality survivorship care for an expanding cancer survivor population. This pilot study tests the application of an e-health platform, “Healthy.me,” in a breast cancer survivor cohort at Liverpool and Macarthur Cancer Therapy Centres, New South Wales, Australia. Methods: Fifty breast cancer patients were recruited to use the Healthy.me website, designed by the Centre of Health Informatics at the University of New South Wales, over a 4-month period. Telephone and online questionnaires were used at 1 and 4 months and a face-to-face feedback at study completion, to gather qualitative and quantitative data regarding feasibility of Healthy.me. Results: Healthy.me was reported to be a useful online resource by most users. Usage declined from 76% at 1 month to 48% at 4 months. Breast cancer survivors enjoyed a variety of tailored information regarding health and life-style issues. Positive aspects of Healthy.me were the convenient access to trusted information, and interaction with their peers and healthcare professionals. Barriers to usage contributing to usage decline were lack of reported patient time to re-access information, limited content updates and technical factors. Conclusions: This pilot study suggested the potential of an e-health strategy such as Healthy.me in addressing the needs of a growing breast cancer survivor population. Ongoing development of a more robust e-health resource and integration with primary care models is warranted

Self-Compassion Interventions and Psychosocial Outcomes: a Meta-Analysis of RCTs

Objectives Self-compassion is a healthy way of relating to one’s self motivated by a desire to help rather than harm. Novel self-compassion-based interventions have targeted diverse populations and outcomes. This meta-analysis identified randomized controlled trials of self-compassion interventions and measured their effects on psychosocial outcomes. Methods This meta-analysis included a systematic search of six databases and hand-searches of the included study’s reference lists. Twenty-seven randomized controlled trials that examined validated psychosocial measures for self-compassion-based interventions met inclusion criteria. Baseline, post and follow-up data was extracted for the intervention and control groups, and study quality was assessed using the PRISMA checklist. Results Self-compassion interventions led to a significant improvement across 11 diverse psychosocial outcomes compared with controls. Notably, the aggregate effect size Hedge’s g was large for measures of eating behavior (g = 1.76) and rumination (g = 1.37). Effects were moderate for self-compassion (g = 0.75), stress (g = 0.67), depression (g = 0.66), mindfulness (g = 0.62), self-criticism (g = 0.56), and anxiety (g = 0.57) outcomes. Further moderation analyses found that the improvements in depression symptoms continued to increase at follow-up, and self-compassion gains were maintained. Results differed across population type and were stronger for the group over individual delivery methods. Intervention type was too diverse to analyze specific categories, and publication bias may be present. Conclusions This review supports the efficacy of self-compassion-based interventions across a range of outcomes and diverse populations. Future research should consider the mechanisms of change
