Lincolnshire Libraries have taken an integrated approach to the provision of information and communications technology (ICT) for lifelong learning, culture, economic and social improvement. Its approach has put it at the forefront of developments within the county, particularly with regard to e‐government. The People’s Network has been a catalyst, but Lincolnshire’s approach, focusing on the basics of training, access and content, and rooted firmly in the requirements of its communities themselves, has developed the People’s Network from being simply a collection of 270 networked computers into a comprehensive and coherent resource, one which is bringing huge benefit to the people of Lincolnshire. It has taken access to ICT outside library buildings through the use of mobile learning units, developed a range of content provision – both in‐house and by communities themselves – and worked with training providers and learndirect to offer tailored training programmes.

Both the academic literature and practitioners have long noted the need for an equity investment mechanism for worker-controlled firms that alleviates investor anxieties without undermining internal workplace democracy. The purpose of this paper is to outline one such possible mechanism.

The proposal locks together the interests of workers and external investors, via non-voting shares with dividends set by a pre-agreed value-added sharing formula. Each worker is paid a base wage, with the average across the firm being a pre-defined multiple of the national minimum wage. Any additional surplus is split into a number of equal “slices”, with each share receiving one slice as its dividend, and the average worker receiving a pre-agreed number of slices as a bonus.

Workers have an incentive to maximise their own incomes, and in so doing, will also automatically maximise the dividends received by investors, obviating the need for the shares to have normal voting rights. Working on this principle of aligned interests, the authors also discuss reinvestment, worker ownership of non-voting shares and possibilities for a secondary share market. The authors show how this proposal will be a significant step in aligning the interests of investors with owner-workers in a democratic, negotiated way that shares both risk and returns, thus making worker-controlled firms more attractive to equity investment.

In light of the recognised problem of underinvestment in worker-controlled firms and the risk of their degeneration, this paper will interest both academics and practitioners in employee ownership, co-operatives and various forms of workplace democracy.

This paper aims to use redundant manipulators to solve the challenge of collision avoidance in construction operations such as welding and painting.

In this paper, a null-space-based task-priority adjustment approach is developed to avoid collisions. The method establishes the relative position of the obstacle and the robot arm by defining the “link space,” and then the priority of the collision avoidance task and the end-effector task is adjusted according to the relative position by introducing the null space task conversion factors.

Numerical simulations demonstrate that the proposed method can realize collision-free maneuvers for redundant manipulators and guarantee the tracking precision of the end-effector task. The experimental results show that the method can avoid dynamic obstacles in redundant manipulator welding tasks.

A new formula for task priority adjustment for collision avoidance of redundant manipulators is proposed, and the original task tracking accuracy is guaranteed under the premise of safety.
