The Slaving Capital in the Era of Abolition: Liverpool's Silent Rejection of the Slave Trade, 1787-1807

<p>In 1787, when the British abolition movement began, the Liverpool slave trade was the largest in the world. Contemporaries throughout Britain, but especially in the port, viewed the slave trade as the primary source of Liverpool’s growth and prosperity in the eighteenth century. Liverpudlians, therefore, reacted negatively to the abolition movement, which they viewed as a threat to both the local and national economy. By 1788, the immense popular support generated by the abolition campaign left Liverpool isolated in its defence of the slave trade. Liverpudlians, however, were not unanimous in their support of the slave trade’s continuance. In 1787 and 1788, a small group of rational dissenters, known as the Roscoe Circle, anonymously contributed to the abolition campaign from Liverpool. The group’s namesake, William Roscoe, went on to be elected Member of Parliament for Liverpool in 1806, and in March 1807 he voted in favour of abolishing the slave trade along with 282 other MPs, against just sixteen, including Liverpool’s other MP. This thesis examines reactions in Liverpool to the British abolition movement between the start of the campaign in 1787 and the passage of the Slave Trade Abolition Act in 1807. It highlights the periods 1787-1788 and 1796-1807 to challenge the view of Liverpool as a town almost uniformly averse to abolition throughout the twenty year campaign. Chapters One and Two examine the immediate pro- and anti-abolition responses in Liverpool in 1787 and 1788, respectively focusing on the contributions of Liverpool slaving merchants to the anti-abolition campaign and on the abolitionist activities of the Roscoe Circle. Drawing on Liverpool guidebooks and a series of letters in the Liverpool Chronicle, Chapter Three then traces the gradual change in popular feeling towards abolition that occurred in Liverpool in the last decade of the British slave trade’s existence. Ultimately, this thesis argues that rapidly dwindling Liverpudlian support for the slave trade from the mid-1790s onward has been under-valued. By 1807 Liverpudlians, wanting to re-affirm cultural ties with the rest of Britain, turned their backs on the slave trade, which had by then become a source of unease and embarrassment.</p>

The Invitation Circle

This article discusses an invitation circle, a process of inviting workshop and classroom participants into collaborative and humanizing inquiry, and provides guidelines for initiating an invitation circle. Drawing from indigenous and posthuman traditions, invitation circles model decolonizing inquiry, encourage participants to develop humanizing connections with one another, and foster imagination of futures unconstrained by the colonial imaginary.

Upper-Limb Muscle Synergy Features in Human-Robot Interaction with Circle-Drawing Movements

The upper-limb rehabilitation robots can be developed as an efficient tool for motor function assessments. Circle-drawing has been used as a specific task for robot-based motor function measurement. The upper-limb movement-related kinematic and kinetic parameters measured by motion and force sensors embedded in the rehabilitation robots have been widely studied. However, the muscle synergies characterized by multiple surface electromyographic (sEMG) signals in upper limbs during human-robot interaction (HRI) with circle-drawing movements are rarely investigated. In this research, the robot-assisted and constrained circle-drawing movements for upper limb were used to increase the consistency of muscle synergy features. Both clockwise and counterclockwise circle-drawing tasks were implemented by all healthy subjects using right hands. The sEMG signals were recorded from six muscles in upper limb, and nonnegative matrix factorization (NMF) analysis was utilized to obtain muscle synergy information. Both synergy pattern and activation coefficient were calculated to represent the spatial and temporal features of muscle synergies, respectively. The results obtained from the experimental study confirmed that high structural similarity of muscle synergies was found among the subjects during HRI with circle-drawing movement by healthy subjects, which indicates healthy people may share a common underlying muscle control mechanism during constrained upper-limb circle-drawing movement. This study indicates the muscle synergy analysis during the HRI with constrained circle-drawing movement could be considered as a task for upper-limb motor function assessment.

Quantitative Assessment of Motor Function for Patients with a Stroke by an End-Effector Upper Limb Rehabilitation Robot

With the popularization of rehabilitation robots, it is necessary to develop quantitative motor function assessment methods for patients with a stroke. To make the assessment equipment easier to use in clinics and combine the assessment methods with the rehabilitation training process, this paper proposes an anthropomorphic rehabilitation robot based on the basic movement patterns of the upper limb, point-to-point reaching and circle drawing movement. This paper analyzes patients’ movement characteristics in aspects of movement range, movement accuracy, and movement smoothness and the output force characteristics by involving 8 patients. Besides, a quantitative assessment method is also proposed based on multivariate fitting methods. It can be concluded that the area of the real trajectory and movement accuracy during circle drawing movement as well as the ratio of force along the sagittal axis in backward point-to-point movement are the unique parameters that are different remarkably between stroke patients and healthy subjects. The fitting function has a high goodness of fit with the Fugl-Meyer scores for the upper limb (R2=0.91, p=0.015), which demonstrates that the fitting function can be used to assess patients’ upper limb movement function. The indicators are recorded during training movement, and the fitting function can calculate the scores immediately, which makes the functional assessment quantitative and timely. Combining the training process and assessment, the quantitative assessment method will farther expand the application of rehabilitation robots.
