Design for social innovation and inclusion.
Designing out crime is a strategy that the UK Design Council continues to profile and support, promoting the use of design as an approach for addressing social challenges and combating crime (UK Design Council 2011). This paper considers the strategy and application of design for social innovation to create an inclusive platform for participation in city locations where youth activity isn't otherwise encouraged. Design and diversionary activities can enhance wellness and contribute to healthier urban communities and these are the issues that Streetsport, an innovative diversionary tactics initiative, has sought to address. As a pilot project that grew into an established programme, Streetsport has proved itself as a vehicle of engagement that uses sport and creative activities to divert and distract disaffected young people (who are considered at risk of offending) from the pressures and challenging circumstances within their communities. Measures of the programme's impact are notable with reductions in both incidents of youth crime and complaints of youth anti-social behaviour in some instances down by over 50%. This paper describes the development of the Streetsport programme that began as a key partnership between Gray's School of Art, Grampian Police and RGU:Sport, with Designers playing a pivotal role in establishing and developing the strategy, for placing a mobile sports and activity arena and for making it visible both digitally (through branding and social media) and on location. Likened to a Trojan Horse, the temporary installation is deployed into the community at targeted strategic sites across Aberdeen city which include seven priority neighbourhoods reported by the Scottish Government as being in the 15% most deprived areas of Scotland (Scottish Index of Multiple Deprivation 2009). As a result of this project, the key stakeholders involved now recognise and value the role of design and designers in developing, implementing and communicating youth services. This paper serves as a case study of how design can be applied to facilitate community engagement and how designers can apply their skills specifically to engage disaffected youth through community-based activities
The early Martian environment: Clues from the cratered highlands and the Precambrian Earth
There is abundant geomorphic evidence to suggest that Mars once had a much denser and warmer atmosphere than present today. Outflow channel, ancient valley networks, and degraded impact craters in the highlands all suggest that ancient Martian atmospheric conditions supported liquid water on the surface. The pressure, composition, and duration of this atmosphere is largely unknown. However, we have attempted to place some constraints on the nature of the early Martian atmosphere by analyzing morphologic variations of highland impact crater populations, synthesizing results of other investigators, and incorporating what is know about the geologic history of the early Earth. This is important for understanding the climatic evolution of Mars, the relative abundance of martian volatiles, and the nature of highland surface materials
Early Mars: A regional assessment of denudation chronology
Within the oldest highland units on Mars, the record of crater degradation indicates that fluvial resurfacing was responsible for modifying the Noachian through middle-Hesperian crater population. Based on crater frequency in the Noachian cratered terrain, age/elevation relations suggest that the highest exposures of Noachian dissected and plateau units became stabilized first, followed by successively lower units. In addition, studies of drainage networks indicate that the frequency of Noachian channels is greatest at high elevations. Together, these observations provide strong evidence of atmospheric involvement in volatile recycling. The long time period of crater modification also suggests that dendritic highland drainage was not simply the result of sapping by release of juvenile water, because the varied geologic units as well as the elevation dependence of stability ages makes it unlikely that subsurface recycling could provide a continuous supply of water for channel formation by sapping. While such geomorphic constraints on volatile history have been established by crater counts and stratigraphic relations using the 1:2M photomosaic series, photogeologic age relationships at the detailed level are needed to establish a specific chronology of erosion and sedimentation. Age relations for discrete erosional slopes and depositional basins will help refine ages of fluvial degradation, assess effectiveness of aeolian processes, and provide a regional chronology of fluvial events

Food habits of Atlantic white-sided dolphins (Lagenorhynchus acutus) off the coast of New England
This paper is not subject to U.S. copyright. The definitive version was published in Fishery Bulletin 107 (2009): 384â394.Although the Atlantic
white-sided dolphin (Lagenorhynchus
acutus) is one of the most common
dolphins off New England, little has
been documented about its diet in
the western North Atlantic Ocean.
Current federal protection of marine
mammals limits the supply of animals
for investigation to those incidentally
caught in the nets of commercial fishermen
with observers aboard. Stomachs
of 62 L. acutus were examined; of
these 62 individuals, 28 of them were
caught by net and 34 were animals
stranded on Cape Cod. Most of the
net-caught L. acutus were from the
deeper waters of the Gulf of Maine. A
single stomach was from the continental
slope south of Georges Bank. At
least twenty-six fish species and three
cephalopod species were eaten. The
predominant prey were silver hake
(Merluccius bilinearis), spoonarm
octopus (Bathypolypus bairdii), and
haddock (Melanogrammus aeglefinus).
The stomach from a net-caught L.
acutus on the continental slope contained
7750 otoliths of the Madeira
lanternfish (Ceratoscopelus maderensis).
Sand lances (Ammodytes spp.)
were the most abundant (541 otoliths)
species in the stomachs of stranded
L. acutus. Seasonal variation in diet
was indicated; pelagic Atlantic herring
(Clupea harengus) was the most
important prey in summer, but was
rare in winter. The average length of
fish prey was approximately 200 mm,
and the average mantle length of
cephalopod prey was approximately
50 mm
Using digital tools in clinical, health and social care research:a mixed-methods study of UK stakeholders
Objective: The COVID-19 pandemic accelerated changes to clinical research methodology, with clinical studies being carried out via online/remote means. This mixed-methods study aimed to identify which digital tools are currently used across all stages of clinical research by stakeholders in clinical, health and social care research and investigate their experience using digital tools.Design: Two online surveys followed by semistructured interviews were conducted. Interviews were audiorecorded, transcribed and analysed thematically.Setting, participants: To explore the digital tools used since the pandemic, survey participants (researchers and related staff (n=41), research and development staff (n=25)), needed to have worked on clinical, health or social care research studies over the past 2 years (2020â2022) in an employing organisation based in the West Midlands region of England (due to funding from a regional clinical research network (CRN)). Survey participants had the opportunity to participate in an online qualitative interview to explore their experiences of digital tools in greater depth (n=8).Results: Six themes were identified in the qualitative interviews: âdefinition of a digital tool in clinical researchâ; âimpact of the COVID-19 pandemicâ; âperceived benefits/drawbacks of digital toolsâ; âselection of a digital toolâ; âbarriers and overcoming barriersâ and âfuture digital tool useâ. The context of each theme is discussed, based on the interview results.Conclusions: Findings demonstrate how digital tools are becoming embedded in clinical research, as well as the breadth of tools used across different research stages. The majority of participants viewed the tools positively, noting their ability to enhance research efficiency. Several considerations were highlighted; concerns about digital exclusion; need for collaboration with digital expertise/clinical staff, research on tool effectiveness and recommendations to aid future tool selection. There is a need for the development of resources to help optimise the selection and use of appropriate digital tools for clinical research staff and participants
