Made by labour : a material and visual history of British labour, c.1780-1924
This is a full-length study of the material and visual culture of the British labour movement in almost half a century. It draws together the fruits of recent research into a comprehensive material and visual analysis of the nineteenth-century labour movement's development. It analyses the meaning of 'labour things', the role they played in the lives of working people and the ways they have influenced the writing of labour history. Over ninety illustrated, expertly contextualised objects are used to narrate the history of British labour in its most crucial phase of development.

Behavioural Skills for Effective Policing
Behavioural skills are essential to effective policing practice and professional development, and are also embedded within the policing competency frameworks. As the police service looks to further redefine its role in the twenty-first century, this critical handbook covers the full range of these proficiencies, from building rapport, applying emotional intelligence, building empathy and resilience to diversity and difference, understanding ethics, and developing coaching and leadership skills.
Each chapter is written by a distinguished serving or former senior police leader and/or policing scholar, bringing together a wealth of experience and understanding and applying this knowledge in context through key case studies and examples. Suitable for serving police officers at all levels, as well as policing lecturers and students aspiring to join the police, this book encourages and enables a people-centred approach to policing that balances the debate that has given disproportionate credence to transactional skills at the expense of a more transformational approach.

Quantitative T1-relaxation corrected metabolite mapping of 12 metabolites in the human brain at 9.4 T
•Quantitative metabolite maps of 12 metabolites in the human brain acquired at 9.4 T.•Voxel-specific T1-weighting corrections for water and metabolites.•Comparisons of T1-weighted and T1-corrected metabolite maps.
Magnetic resonance spectroscopic imaging (MRSI) is a non-invasive imaging modality that enables observation of metabolites. Applications of MRSI for neuroimaging have shown promise for monitoring and detecting various diseases. This study builds off previously developed techniques of short TR, 1H FID MRSI by correcting for T1-weighting of the metabolites and utilizing an internal water reference to produce quantitative (mmol kg−1) metabolite maps. This work reports and shows quantitative metabolite maps for 12 metabolites for a single slice. Voxel-specific T1-corrections for water are common in MRSI studies; however, most studies use either averaged T1-relaxation times to correct for T1-weighting of metabolites or omit this correction step entirely. This work employs the use of voxel-specific T1-corrections for metabolites in addition to water. Utilizing averaged T1-relaxation times for metabolites can bias metabolite maps for metabolites that have strong differences between T1-relaxation for GM and WM (i.e. Glu). This work systematically compares quantitative metabolite maps to single voxel quantitative results and qualitatively compares metabolite maps to previous works.

Lethal force
\"In the final volume of Dixon's Nightwing run, Dick Grayson is emotionally and physically pushed to his breaking point. Dick Grayson searches within for what it is to be a hero in the aftermath of the Joker's latest reign of terror. Just before he can catch his breath, another shocking development threatens everything he has ever known, as Bruce Wayne is charged with murder! This volume also features appearances from the Flash, Blue Beetle and the rest of the Bat-Family.\"-- Provided by publisher.

Early Sri Lankan coastal site tracks technological change and estuarine resource exploitation over the last ca. 25,000 years
The island of Sri Lanka was part of the South Asian mainland for the majority of the past 115,000 years, and connected most recently during the Last Glacial Maximum via the now submerged Palk Strait. The degree to which rising sea levels shaped past human adaptations from the Pleistocene and into the mid to late Holocene in Sri Lanka has remained unclear, in part because the earliest reliable records of human occupation come from the island’s interior, where cave sites have revealed occupation of tropical forest ecosystems extending back to 48 thousand years (ka). The island’s earliest known open-air sites are all much younger in date, with ages beginning at 15 ka and extending across the Holocene. Here we report the earliest well-dated open-air coastal site in Sri Lanka, Pathirajawela, which records human occupation back to ca. 25,000 years ago. We show that humans at Pathirajawela consistently adapted to changing ecosystems linked to sea level transgression and coastal evolution from the Last Glacial Maximum into the Holocene. The presence of anthropogenic shell midden deposits at the site from ca. 4.8 ka, focused almost exclusively on a single taxon, indicates intensification of estuarine resource exploitation, as humans responded to opportunities presented by the formation of new coastal ecosystems.

Wales and socialism
This study examines the spread of socialism in late-Victorian and Edwardian Wales, paying particular attention to the relationship between socialism and Welsh national identity. Welsh opponents of socialism often claimed it to be a foreign import, whereas socialists often asserted that the Welsh were socialist by nature. This study - the first full-scale study of the influence of early socialism across all of Wales - demonstrates that the reality was more complex than either assertion would admit. Rather than focusing on the structural growth of socialism, the topic is discussed in terms of the spread of ideas and the development of a political culture. The study culminates in a discussion of attempts, in the period before the Great War, to create a specifically Welsh socialist tradition. In approaching the topic from this angle, this study restores a part of the lost diversity of British socialism that is of striking contemporary relevance.

Experimental and Numerical Investigation of the Engine Operational Conditions’ Influences on a Small Un-Scavenged Pre-Chamber’s Behavior
Despite significant benefits in terms of the ignition enhancement, the strength and timing of the turbulent flame jets subsequently issuing into the main chamber strongly depend on the pre-chamber combustion process and, thus, are sensitive to the specific engine operating conditions it experienced. This poses considerable difficulties in optimizing engine operating conditions as well as controlling engine performance. This paper investigates the influence of engine operating conditions on the pre-chamber combustion event using both experimental and numerical methods. A miniaturized piezo-electric pressure transducer was designed to be placed inside the engine cylinder head to record the pre-chamber inner volume pressure, in addition to conventional pressure indication inside the main chamber. The pressure difference between the main chamber and the pre-chamber (Δp = ppre-chamber
- pmain chamber
) served as an indicator of the pre-chamber combustion event, through the study of the crank angle resolved Δp under different engine operating conditions. The variations include spark timing, air-fuel ratio and engine speed, as well as engine intake air temperature and boost pressure, for which a single-parameter sensitivity approach was carried out. 3D-CFD simulation in the RANS context and 0D modeling was further employed to estimate the turbulence level and thermo-physical conditions inside the pre- and main chambers in dependence of the engine operating conditions. The results indicate that the Δp peak value and its timing show the highest sensitivity to the air-fuel ratio variation, followed by the intake air temperature, while the sensitivity of Δp peak value and its timing to the pressure difference and the absolute pressure level at spark timing were observed to be considerably lower. Based on the observations, two correlations were proposed to predict the Δp peak value and its timing for which successful validation against a large number of engine operating conditions was demonstrated.
