China's Post-Listian Rise: Beyond Radical Globalisation Theory and the Political Economy of Neoliberal Hegemony

Abstract: While China's rise has been much discussed, its meaning continues to be contested. This is true in radical international political economy, where, for example, it was the subject of (often polarised) debates between Giovanni Arrighi and David Harvey prior to Arrighi's death in 2009. This reflected a broader debate in IPE between development theory and radical globalisation analysis. The key point of contention is whether China's rise represents a challenge to or further consolidation of neoliberal hegemony on a global scale. This article critically scrutinises some of the key assumptions of the radical globalisation approach, specifically, that China represents another form of the ‘competition state’ whose development aspirations have been radically constrained by global ‘new constitutionalism’ and American monetary power so as to conform to neoliberalism. Deploying a structurationist approach to global governance and an eclectic/regulatory analysis of the Chinese state, I argue that China has challenged ...

Analysis of human-robot spatial behaviour applying a qualitative trajectory calculus

Abstract: The analysis and understanding of human-robot joint spatial behaviour (JSB) - such as guiding, approaching, departing, or coordinating movements in narrow spaces - and its communicative and dynamic aspects are key requirements on the road towards more intuitive interaction, safe encounter, and appealing living with mobile robots. This endeavours demand for appropriate models and methodologies to represent JSB and facilitate its analysis. In this paper, we adopt a qualitative trajectory calculus (QTC) as a formal foundation for the analysis and representation of such spatial behaviour of a human and a robot based on a compact encoding of the relative trajectories of two interacting agents in a sequential model. We present this QTC together with a distance measure and a probabilistic behaviour model and outline its usage in an actual JSB study. We argue that the proposed QTC coding scheme and derived methodologies for analysis and modelling are flexible and extensible to be adapted for a variety of other scenarios and studies.

Equations of motion of rotating composite beam with a nonconstant rotation speed and an arbitrary preset angle

Abstract: In the presented paper the equations of motion of a rotating composite Timoshenko beam are derived by utilising the Hamilton principle. The non-classical effects like material anisotropy, transverse shear and both primary and secondary cross-section warpings are taken into account in the analysis. As an extension of the other papers known to the authors a nonconstant rotating speed and an arbitrary beam’s preset (pitch) angle are considered. It is shown that the resulting general equations of motion are coupled together and form a nonlinear system of PDEs. Two cases of an open and closed box-beam cross-section made of symmetric laminate are analysed in details. It is shown that considering different pitch angles there is a strong effect in coupling of flapwise bending with chordwise bending motions due to a centrifugal force. Moreover, a consequence of terms related to nonconstant rotating speed is presented. Therefore it is shown that both the variable rotating speed and nonzero pitch angle have significant impact on systems dynamics and need to be considered in modelling of rotating beams.

Social work in the time of the COVID-19 pandemic: All in this together?

Abstract: With the benefit of hindsight, our last Editorial (‘Working on the frontline: what war are we talking about?’) might appear ill-judged, as, in the space of a few weeks, the language of combat has come to dominate our news programmes. Across the globe, nations find themselves in lockdown in order to fight the spread of the coronavirus (COVID-19), with social work and social care being no exception. Problems caused by isolation in residential care for older people; the exacerbation of anxiety and paranoia for those with long-term mental health problems; families prohibited from embracing their loved ones at the end of life; the operation of social distancing in prisons; how to survive, never mind self-isolate, at home for people who have no home; the risks posed to social care staff who all too often do not have adequate personal protection equipment nor are they able to use touch as they communicate with vulnerable people in these very particular circumstances—this is indeed the stuff of ‘front-line’ practice, as we write and for the foreseeable future. Is this not, indeed, a battle, one which, as our political leaders constantly remind us, we are all in together, the virus being no respecter of persons? Despite this, the essential messages of our last Editorial hold good in this world in which keeping a balance between realism or denial, panic or fortitude, shifts from day to day. The truth is that some are much better placed than others to get through this and, as ever, social work must look out for and speak for, the most marginalised and vulnerable in our society. Now, more than ever, we must take the lead in building coalitions that will share and adapt existing expertise to address issues of well-being and survival for those who do not have the resources to do this for themselves. While our attention has turned to life in the ‘new normal’ state of emergency and the discussion over critical care beds and ventilators dominates the news, it is easy to overlook the other reality that people continue to experience breakdown and crisis and need routine support services. The first three articles in this issue, all from the UK, concern three groups for whom this is particularly relevant. It might also be the case, without stretching this too far, that we can take lessons learned from these
