    Collaborative learning: a connected community approach

    Collaborative Learning in group settings currently occurs across a substantial portion of the UK Higher Education curriculum. This style of learning has many roots including: Enterprise in Higher Education, Action Learning and Action Research, Problem Based Learning, and Practice Based Learning. As such our focus on Collaborative Learning development can be viewed as an evolutionary. This collaborative and active group learning provides the foundation for what can be collectively called connectivist ‘Learning Communities’. In this setting a primary feature of a ‘Learning Community’ is one that carries a responsibility to promote one another’s learning. This paper will outline a developmental collaborative learning approach and describe a supporting software environment, known as the Salford Personal Development Environment (SPDE), that has been developed and implemented to assist in delivering collaborative learning for post graduate and other provision. This is done against a background of much research evidence that group based activity can enhance learning. These findings cover many approaches to group based learning and over a significant period of time. This paper reports on work-in-progress and the features of the environment that are designed to help promote individual and group or community learning that have been influenced by the broad base of research findings in this area

    Lenin’s Lens: The Occupy Movement, an Infantile Disorder?

    This paper offers a theoretical critique of the Occupy movement by drawing on V.I. Lenin’s work, Left-wing Communism: an Infantile Disorder (LWC). This work emphasizes the importance of recognizing political power within institutionalized political systems, for example, trade unions and parliamentary democracy. We bring the ideas contained in this work to bear on the Occupy movement by drawing on 20 activist accounts from two UK Occupy camps to argue that the Occupy movement was an earlier phase of a developing political challenge to neoliberalism. In this respect, Occupy was an immature politics unlikely to lead to social change. However, recent research suggests that the creation of a new wave of ‘movement parties’ (della Porta et al., 2017) are a more organized and politically mature response to neoliberal austerity, which to some extent grew out of the mass movement assemblies like the Occupy movement. By applying Lenin’s ideas to analyse the main political practices of Occupy, this paper argues that a Leninist viewpoint could offer some practical improvements towards the political strategy of new movements by being part of a coalition of activists and trade unionists, with the ultimate aim of working within parliamentary democracy

    Flexural fatigue performance of CFRP prestressed concrete poles

    Carbon fibre reinforced polymer (CFRP) prestressed concrete poles offer a durable, light-weight alternative to conventional steel-reinforced or prestressed concrete poles. In particular, the corrosion resistance of the CFRP tendons can result in lower maintenance costs and a reduction in the required concrete cover. For lighting poles used in pedestrian or low-trafficked areas, wind loading represents a dominant load case. The wind acts as a transient force and can blow from any direction. It is therefore of interest to investigate how CFRP prestressed lighting poles perform under repeated cyclic loads and/or load reversals. Experiments were carried out on pole sections tested horizontally. These included a static control test and a conventional fatigue test where a cyclic load was applied in a downwards direction for 2 million cycles. Three further fatigue tests where the load direction changed, either after a defined number of cycles or within a load cycle, were also conducted. It was found that all the poles performed adequately for 1–2 million cycles of loading and that the majority of any deflection increases occurred within the first 50,000 cycles. It is believed that repeated cyclic loading may have increased the tendon debonding at the crack locations. Localised debonding potentially relieves the stress in the outermost tendon layer which delays the onset of failure and allows the inner tendon layers to take up further stress thus leading to a higher load carrying capacity. Loading orientation reversal from a downwards to an upwards direction within a loading cycle did not result in a greater stiffness degradation when compared to the other fatigue tests. The initial findings suggest that in-service cyclic loading and load reversals will not be detrimental to the performance of CFRP prestressed concrete poles.
