Crossing borders for transformative professional learning about health and physical education policy through the Policy Process Case Method
The Policy Process Case Method (PPCM) is a recent innovation for (health and physical) education professionals to transform their complex policy experiences into practical insights. This method engages professionals across roles and geographical borders in sustained reflexive dialogue to collaboratively interrogate their policy experiences through policy theories. In this ∼1.5-year PPCM investigation, our group (i.e. two curriculum officers, one …

Subglacial meltwater routes of the Fennoscandian Ice Sheet
Subglacial drainage systems are crucial elements of glaciers and ice sheets because they modulate ice flow velocity. However, logistical challenges of measuring subglacial processes beneath contemporary ice and natural limitations in long-term monitoring hinder our understanding about their spatio-temporal evolution. Subglacial meltwater landforms created by palaeo-ice sheets are records of past subglacial drainage systems and offer the potential…

The glacial geomorphology of the western cordilleran ice sheet and Ahklun ice cap, Southern Alaska
During the late Wisconsinan, Southern Alaska was covered by two large ice masses; the western arm of the Cordilleran Ice Sheet and the Ahklun Mountains Ice Cap. Compared to the other ice sheets that existed during this period (e.g. the British-Irish, Laurentide and Fennoscandian ice sheets), little is known about the geomorphology they left behind. This limits our understanding of their flow pattern and retreat. Here we present systematic mapping…
Flow-stripes and foliations of the Antarctic ice sheet
Longitudinal surface structures (LSSs) are flow parallel curvilineations visible on satellite imagery which are commonly observed on ice shelves, ice streams and glaciers. Their distribution and genesis has the ability to inform us about ice sheet history and glacial processes. Multiple hypotheses have been proposed for their formation. Here, we present continental-scale mapping of these features across the entire Antarctic ice sheet. The accompa…
Ice streams in the Laurentide Ice Sheet
Rapidly flowing ice streams dominate the drainage of continental ice sheets and are a key component of their mass balance. Due to their potential impact on sea level, their activity in the Antarctic and Greenland Ice Sheets has undergone detailed scrutiny in recent decades. However, these observations only cover a fraction of their 'life-span' and the subglacial processes that facilitate their rapid flow are very difficult to observe. To circumve…
Manual mapping of drumlins in synthetic landscapes to assess operator effectiveness
Mapped topographic features are important for understanding processes that sculpt the Earth's surface. This paper presents maps that are the primary product of an exercise that brought together 27 researchers with an interest in landform mapping wherein the efficacy and causes of variation in mapping were tested using novel synthetic DEMs containing drumlins. The variation between interpreters (e.g. mapping philosophy, experience) and across the …
An updated moraine map of Far NE Russia
Barr and Clark published a series of maps depicting the distribution of end moraines across Far NE Russia. These moraines outlined the former distribution and dimensions of glaciers, and were identified through the analysis of Landsat ETM+ satellite images (15- and 30-m resolution). Now, a number of freely available digital elevation model (DEM) datasets are available, which cover the entire ∼4 million km2 of Far NE Russia. These include the 30-m…
Dating constraints on the last British-Irish Ice Sheet
Please click here to download the map associated with this article. We present a collation of 975 published dates relevant to the timing of build-up and retreat of ice over the British Isles during the most recent glacial stage. The spatial distribution of dates is essential to interpreting the evolution of the ice sheet over time and space. For this reason the dates are presented as a map showing the spatial distribution across the UK and Irelan…
Changing Lives
In 2004 the then Scottish Executive launched the 21st Century Social Work Review. The review report, Changing Lives, addressed perceived shortcomings in statutory social work services, claiming to offer a fundamental review of the profession. This paper argues that, rather than offering any significantly new principles or policies, the drift of the Changing Lives process was chiefly to refurnish the discourse in which statutory social work is con…
From rules to encounters
This article addresses what theories, methods and procedures practitioners ought to adopt in order to resolve ethical problems in service practice. Several approaches are identified from the literature but none are entirely credible in themselves or sufficient for reliably founded ethical decision-making. The article argues that addressing ethical issues should rather be understood as a hermeneutic process. Gadamer's historically informed hermene…
Subglacial bedforms of the last British Ice Sheet
Please click here to download the map associated with this article. Subglacial bedforms are a characteristic feature of formerly glaciated landscapes. Formed parallel (e.g. drumlins) or transverse (ribbed moraine) to ice flow their preserved distribution is a valuable record of ice sheet configuration. To date these landforms have been underused in Britain such that we have only a simple static view of the flow patterns of the last British Ice Sh…
An Automated Model to Identify Heart Failure Patients at Risk for 30-Day Readmission or Death Using Electronic Medical Record Data
BACKGROUND: A real-time electronic predictive model that identifies hospitalized heart failure (HF) patients at high risk for readmission or death may be valuable to clinicians and hospitals who care for these patients. METHODS: An automated predictive model for 30-day readmission and death was derived and validated from clinical and nonclinical risk factors present on admission in 1372 HF hospitalizations to a major urban hospital between Januar…
The Woman Who Walked into the Sea
Alice Wexler's new book, The Woman Who Walked into the Sea: Huntington's and the Making of Genetic Disease, builds on her memoir Mapping Fate (Berkeley: University of California Press, 1995), which blended the histories of her family and Huntington's Disease research. That study drew on bioethics, women's studies, and psychoanalysis while illustrating the value of interdisciplinary collaboration. The Woman Who Walked into the Sea can also be read…
A geomorphological overview of glacial landforms on the Icelandic continental shelf
Please click here to download the map associated with this article. The availability of a bathymetric database that covers about 80% of the Icelandic shelf has made it possible to produce a geomorphological map of the glacial landforms. The digital elevation model of the bathymetry was analyzed as a series of shaded relief images. Trough edges, bulging trough mouths, moraines, eskers, melt water channels, streamlined bedrock and streamlined drift…
Distribution and pattern of moraines in Far NE Russia reveal former glacial extent
Please click here to download the map associated with this article. Here we present a series of six maps illustrating the distribution of end moraines in Far NE Russia. The maps are the first to systematically document the distribution of moraines across this region from the Verkhoyansk Mountains at the westernmost limit of our study area to the Chukchi Peninsula in the NE and to Kamchatka in the south, covering almost 4 million km2. Moraines wer…

Subglacial bedforms of the Irish Ice Sheet
Please click here to download the map associated with this article. The last Irish Ice Sheet has a long history of investigation, but its most basic properties are still debated. A palaeo-glaciological ‘inversion’ of the glacial geomorphological record has elsewhere proven an effective means to reconstruct former ice sheets at ice sheet scale. To this end, this paper describes new glacial geomorphological mapping of the Irish landscape, using Dig…
Professional Responsibility, Misconduct and Practical Reason
This paper considers the accountability of professionals who are involved in situations of the failure of their organization to perform its expected role properly; the case of infant Caleb Ness, who died despite the surveillance of welfare agencies, is taken as an illustration. Following Bovens (“The Quest for Responsibility: Accountability and Citizenship in Complex Organisations”, Cambridge University Press, Cambridge, 1998), it is accepted tha…
Geomorphological Map of Ribbed Moraines on the Dubawnt Lake Palaeo-Ice Stream Bed
Please click here to download the map associated with this article. The beds of active ice streams in Greenland and Antarctica are largely inaccessible, hindering a full understanding of the processes that initiate, sustain and inhibit fast ice flow in ice sheets. Detailed mapping of the glacial geomorphology of palaeo-ice stream tracks is, therefore, a valuable tool for exploring the basal processes that control their behaviour. In this paper we…

The glacial geomorphology of Kola Peninsula and adjacent areas in the Murmansk Region, Russia
A map of the glacial geomorphology of Kola Peninsula and adjacent areas in the Murmansk region, northwestern Russia, is presented.The primary data source for identification and classification of landforms has been Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite images, and aerial photograph interpretation and field work in selected areas.The map, at the scale 1:900,000, consists of over 20,000 landforms pertaining to the Quaternary glaci…
Distribution of Ribbed Moraine in the Lac Naococane Region, Central Québec, Canada
Please click here to download the map associated with this article. Ribbed moraines are large subglacially formed transverse ridges that cover extensive areas of the beds of the former Laurentide, Fennoscandian and Irish ice sheets. Since the flow speeds and stability of ice sheets are known to be sensitive to conditions operating at the bed, a full understanding of the processes of ribbed moraine genesis are critical if we are to appreciate thei…

Observing the lighthouse
This paper discusses the nature of codes of ethics in social work. The desirability of defining rights and obligations in social services is widely accepted, but formal ethical codes often seem both excessively ambitious and insufficiently precise. Their usefulness is thus cast into doubt. The paper considers the influence of major traditions of moral theory and examines the nature of professional codes. It is argued that the precepts embodied in…
