Glaciodynamics of the central sector of the last British–Irish ice sheet in Northern England

The central sector of the last British–Irish Ice Sheet (BIIS) was characterised by considerable complexity, both in terms of its glacial stratigraphy and geomorphological signature. This complexity is reflected by the large number and long history of papers that have attempted to decipher the glaciodynamic history of the region. Despite significant advances in our understanding, reconstructions remain hotly debated and relatively local, thereby hindering attempts to piece together BIIS dynamics. This paper seeks to address these issues by reviewing geomorphological mapping evidence of palimpsest flow signatures and providing an up-to-date stratigraphy of the region. Reconciling geomorphological and sedimentological evidence with relative and absolute dating constraints has allowed us to develop a new six-stage glacial model of ice-flow history and behaviour in the central sector of the last BIIS, with three major phases of glacial advance. This includes: I. Eastwards ice flow through prominent topographic corridors of the north Pennines; II. Cessation of the Stainmore ice flow pathway and northwards migration of the North Irish Sea Basin ice divide; III. Stagnation and retreat of the Tyne Gap Ice Stream; IV. Blackhall Wood–Gosforth Oscillation; V. Deglaciation of the Solway Lowlands; and VI. Scottish Re-advance and subsequent final retreat of ice out of the central sector of the last BIIS. The ice sheet was characterised by considerable dynamism, with flow switches, initiation (and termination) of ice streams, draw-down of ice into marine ice streams, repeated ice-marginal fluctuations and the production of large volumes of meltwater, locally impounded to form ice-dammed glacial lakes. Significantly, we tie this reconstruction to work carried out and models developed for the entire ice sheet. This therefore situates research in the central sector within contemporary understanding of how the last BIIS evolved over time.

Timing and depositional environments of a Middle Pleistocene glaciation of northeast England: New evidence from Warren House Gill, County Durham

At various times during the Quaternary, north-eastern England was a zone of confluence between dynamic ice lobes sourced from the Pennines, northern Scotland, the Cheviots, and Scandinavia. The region thus has some of the most complex exposures of Middle to Late Pleistocene sediments in Britain, with both interglacial and glacial sediments deposited in terrestrial and marine settings. We investigated sedimentary sequences exposed on the coastline of County Durham at Warren House Gill, and present a new model of British and Fennoscandian Ice Sheet interaction in the North Sea Basin during the Middle Pleistocene. The stratigraphy at Warren House Gill consists of a lower diamicton and upper estuarine sediments, both part of the Warren House Formation. They are separated from the overlying Weichselian Blackhall and Horden tills by a substantial unconformity. The lower diamicton of the Warren House Formation is re-interpreted here as an MIS 8 to 12 glaciomarine deposit containing ice-rafted lithics from north-eastern Scotland and the northeast North Sea, and is renamed the ‘Ash Gill Member’. It is dated by lithological comparison to the Easington Raised Beach, Middle Pleistocene Amino Acid Racemisation values, and indirectly by optically stimulated luminescence. The overlying shallow subaqueous sediments were deposited in an estuarine environment by suspension settling and bottom current activity. They are named the ‘Whitesides Member’, and form the uppermost member of the Warren House Formation. During glaciation, ice-rafted material was deposited in a marine embayment. There is no evidence of a grounded, onshore Scandinavian ice sheet in County Durham during MIS 6, which has long been held as the accepted stratigraphy. This has major implications for the currently accepted British Quaternary Stratigraphy. Combined with recent work on the Middle Pleistocene North Sea Drift from Norfolk, which is now suggested to have been deposited by a Scottish ice sheet, the presence of a Scandinavian ice sheet in eastern England at any time during the Quaternary is becoming increasingly doubtful.

Independence referendums: who should vote and who should be offered citizenship?

In this EUDO CITIZENSHIP Forum Debate, several authors consider the interrelations between eligibility criteria for participation in independence referendum (that may result in the creation of a new independent state) and the determination of putative citizenship ab initio (on day one) of such a state. The kick-off contribution argues for resemblance of an independence referendum franchise and of the initial determination of the citizenry, critically appraising the incongruence between the franchise for the 18 September 2014 Scottish independence referendum, and the blueprint for Scottish citizenship ab initio put forward by the Scottish Government in its 'Scotland's Future' White Paper. Contributors to this debate come from divergent disciplines (law, political science, sociology, philosophy). They reflect on and contest the above claims, both generally and in relation to regional settings including (in addition to Scotland) Catalonia/Spain, Flanders/Belgium, Quebec/Canada, Post-Yugoslavia and Puerto-Rico/USA.

Trans/national dis/connections: silenced networks and strained belongings with reference to Albinia Catherine MacKay and Una Marson

This paper seeks to examine the particular operations of gender and cultural politics that both shaped and restrained possible 'networked' interactions between Jamaican women and their British 'motherlands' during the first forty years of the twentieth century. Paying particular attention to the poetry of Albinia Catherine MacKay (a Scots Creole) and the political journalism of Una Marson (a black Jamaica), I shall seek to examine why both writers speak in and of voices out of place. MacKay's poems work against the critical pull of transnational modernism to reveal aesthetic and cultural isolation through a model of strained belonging in relation to both her Jamaica home and an ancestral Scotland. A small number of poems from her 1912 collection that are dedicated to the historical struggle between the English and Scots for the rule of Scotland and cultural self-determination, some of which are written in a Scottish idiom, may help us to read the complex cultural negotiations that silently inform the seemingly in commensurability of location and locution revealed in these works. In contrast, Marson's journalism, although less known even than her creative writings, is both politically and intellectually radical in its arguments concerning the mutual articulation of race and gender empowerment. However, Marson remains aware of her inability to articulate these convictions with force in a British context and thereby of the way in which speaking out of place also silences her.

How well can we model stream phosphorus concentrations in agricultural catchments?

Mechanistic catchment-scale phosphorus models appear to perform poorly where diffuse sources dominate. We investigate the reasons for this for one model, INCA-P, testing model output against 18 months of daily data in a small Scottish catchment. We examine key model processes and provide recommendations for model improvement and simplification. Improvements to the particulate phosphorus simulation are especially needed. The model evaluation procedure is then generalised to provide a checklist for identifying why model performance may be poor or unreliable, incorporating calibration, data, structural and conceptual challenges. There needs to be greater recognition that current models struggle to produce positive Nash–Sutcliffe statistics in agricultural catchments when evaluated against daily data. Phosphorus modelling is difficult, but models are not as useless as this might suggest. We found a combination of correlation coefficients, bias, a comparison of distributions and a visual assessment of time series a better means of identifying realistic simulations.

Better dead: J. M. Barrie’s first book and the shilling fiction market

This article provides a critical and bibliographical discussion of J. M. Barrie’s neglected first book, Better Dead, published by Swan Sonnenschein, Lowrey & Co. in 1887. Drawing on previously unexamined evidence in the Sonnenschein archive, it shows how this shilling novel was marketed and sold to its readers at railway bookstalls, and argues that the content and style of the story was conditioned by its form. Examining the many references and allusions in the story, it proposes that the work is best understood as a satire on contemporary political, social and literary themes. The article also shows how, contrary to all published accounts, the author actually earned a small amount of money from a work which, in spite of his efforts, refused to stay dead.

Response of the North Atlantic wave climate to atmospheric modes of variability

This study investigates the relationship between the wind wave climate and the main climate modes of atmospheric variability in the North Atlantic Ocean. The modes considered are the North Atlantic Oscillation (NAO), the East Atlantic (EA) pattern, the East Atlantic Western Russian (EA/WR) pattern and the Scandinavian (SCAN) pattern. The wave dataset consists of buoys records, remote sensing altimetry observations and a numerical hindcast providing significant wave height (SWH), mean wave period (MWP) and mean wave direction (MWD) for the period 1989–2009. After evaluating the reliability of the hindcast, we focus on the impact of each mode on seasonal wave parameters and on the relative importance of wind-sea and swell components. Results demonstrate that the NAO and EA patterns are the most relevant, whereas EA/WR and SCAN patterns have a weaker impact on the North Atlantic wave climate variability. During their positive phases, both NAO and EA patterns are related to winter SWH at a rate that reaches 1 m per unit index along the Scottish coast (NAO) and Iberian coast (EA) patterns. In terms of winter MWD, the two modes induce a counterclockwise shift of up to 65° per negative NAO (positive EA) unit over west European coasts. They also increase the winter MWP in the North Sea and in the Bay of Biscay (up to 1 s per unit NAO) and along the western coasts of Europe and North Africa (1 s per unit EA). The impact of winter EA pattern on all wave parameters is mostly caused through the swell wave component.

A geochemical and lead isotopic record from a small pond in a remote equatorial island, Fernando de Noronha, Brazil

A 72 cm long core was collected from Lagoa da Viracao (LV), a small poind in the Fernando de Noronha island, northern Brazil. Sediments from the lower section of the core (20-72 cm depth) contain essentially mineral matter, while in the upper section (0-20 cm depth) mineral matter is mixed with organic matter. Lithogenic conservative elements - Si, Al, Fe, Ti, Co, Cr, Cu, Ba, Ga, Hf, Nb, Ni, Y, V, Zn, Zr and REE - exhibit remarkably constant values throughout the core, with concentrations similar to those of the bedrock. The vertical distribution of soluble elements - Ca, Mg, Na, K, P, Mn and Sr - is also homogeneous, but these elements are systematically depleted in relation to the bedrock. LOI, TOC, Br, Se, Hg and Pb, although showing nearly constant values in the lower section of the core, are significantly enriched in the upper section. The concentration profiles of Br and Se suggest that they may be accounted for by natural processes, related to the slight affinity of these elements for organic matter. On the other hand, the elevated levels of Hg and Pb in recent sediments may be explained by their long-range atmospheric transport and deposition. Furthermore, the isotopic composition of Pb clearly indicates that anthropogenic sources contributed to the Pb burden in the uppermost pond sediments.

Nurses' perceived training needs in child protection issues

Purpose – The purpose of this research is to explore nurses' perceptions of their current skills and knowledge and training needs to identify cases of child abuse and their understanding of their roles and responsibilities in relation to child abuse. Nurses, including health visitors and midwives, have been recognised as having a key role in the protection and care of children, especially in identifying and referring possible cases of child abuse and neglect.

Design/methodology/approach – A structured questionnaire concerning knowledge and training needs in child protection was sent to all nurses employed in a Scottish NHS Primary Care Trust (approximately 1,900), of whom one-third (667) responded. These survey results were complemented by semi-structured interviews with 99 members of the nursing workforce.

Findings – Almost all training in child protection had been confined to health visitors, resulting in the Trust giving an implicit message that child protection is not a role in which other nurses need have any involvement. In general, those nurses who both worked with children and had involvement in child protection issues, considered themselves to be most in need of knowledge around child protection work, to have the greatest level of knowledge and to consider further training a priority.

Research limitations/implications – Nurses who had an interest or involvement in child protection work were more likely to participate in the research, which may have biased the results.

Practical implications – Training strategies need to address the diversity of nurses' involvements in child protection work through the development of training programmes which are appropriate for different workplaces and different occupational groupings. Nurses in some settings will need to be first convinced they have the potential to play an important role in protecting children from abuse and neglect.

Originality/value – Many NHS Trusts have in recent years introduced mandatory training in child protection for all staff in contact with children. However, previously published studies have considered training issues only in respect of nurses identified as working directly with children, whereas this study explores child protection issues for all nurses employed in a primary care NHS Trust.

Child protection and public health: nurses' responsibilities

Background. Health care workers have been recognized as having a key role in the protection and care of Scotland's children, particularly in respect of identification and detection of child abuse. Nurses, especially health visitors, are often the first professionals to suspect that child abuse has taken place. While previous research has found that health visitors have primarily perceived their role as that of providing support and advice to vulnerable families, there are pressures on them to fulfil a more narrow surveillance role. Concurrent with a lack of clarity about the role of health visitors in child protection, there has been increasing recognition that other nurses can also make an important contribution, including those who do not work directly with children.

Aims. The aim of the study was to explore nurses' understanding of their professional responsibilities in relation to child protection, and the potential for nurses to be involved in the protection of children from abuse.

Methods. A qualitative interview-based design was used, and 99 nurses working in an National Health Service trust in a Scottish city were interviewed, either individually or in groups, about their professional involvements in child protection issues. Interview data were subjected to thematic analysis.

Findings. There was lack of consensus among interviewees about the nursing remit in child protection issues, particularly with respect to the extent to which nurses should actively seek to detect cases of child abuse. An emphasis on identification and detection was not easily accepted by many nurses, and was perceived by some to be a change from their more traditional role of supporting families, as well as being potentially in conflict with some public health responsibilities.

Conclusion. In spite of the perception of some nurses that there is a sharp divide between child protection work and public health interventions, many of the child protection roles identified by nurses, such as supporting families, parenting education and service development, are clearly within the ambit of contemporary notions of public health. Furthermore, it is clear that there is a role in child protection for a much wider group of nurses than health visitors.
