Problematising ‘happiness’: A critical explanation of the UK’s happiness agenda
Issues of ‘wellbeing’ and ‘happiness’ are becoming more and more prevalent in discussions of social policy and in the provision of healthcare services. In recent years, the maximisation of a nation’s ‘happiness’ has emerged as both a key policy objective and as a central focus within social, political and economic research, with public policy makers around the world having demonstrated a growing interest in national accounts of ‘wellbeing’. In the UK context, this growing interest is comprised of a perceived need to ‘know’ ‘happiness’ and ‘wellbeing’ better, so that they might be maximised. Such attitudes and beliefs made possible the introduction of four new questions to the Annual Population Survey that were specifically designed to measure the UK’s “subjective wellbeing” (now referred to as “individual life satisfaction” following revisions in subsequent years). In addition to this, in 2010 a non-profit organisation named Action for Happiness (AfH) was founded which sought to maximise the ‘happiness’ of society by offering individual members help and training towards living a ‘happier’ life - an endeavour which is understood to be necessitated by the stagnation of ‘happiness’ in modern Western societies. This thesis seeks to critically account for the emergence of such social and political practices – or ‘happiness agenda’ - and does so from a poststructuralist, post-Marxist standpoint. This is achieved by utilising the specific methodological strategy developed by Glynos & Howarth (2007) which constitutes a retroductive, deconstructive, approach to accounting for socio-political phenomena. In doing so, three types of logics underpinning these practices are identified, presenting an explanation as to what, how and why these practices are. Accounting for the emergence of such a ‘happiness agenda’ enables it (and its emergence) to be critiqued – specifically, the notion contained within it that maximised individual ‘happiness’ constitutes social progression. Indeed, central to the critique of the ‘happiness agenda’ that this thesis presents is an acknowledgement of the need of a socio-political equality agenda, where ‘social progression’ is instead conceptualised as maximised social equality
一种磁浮式驱动装置
本实用新型提供了一种磁浮式驱动装置。该装置采用磁浮单元,并将其中磁浮支撑体一端与移动工件台固定相连,另一端的凸出部分承载永磁动子,与主支座的凸出部分所承载的永磁定子呈上下相对、存间隙的放置结构,从而当直线电机动子通以电流,使直线电机动子与永磁定子之间产生直线推力时,一方面能够带动承载着移动部件的移动工件台随滑块在导轨上移动,另一方面由于直线电机动子与定子间的法向吸力平衡该移动部件的负载重力,从而有效地降低了导轨的负载,大大减小了其机械磨损,提高了使用寿命
一种直驱式回转平移装置

二维直线运动平台几何误差建模与数字化分析
针对二维直线运动平台的定位精度受到绕X、Y、Z三个方向转动产生的角位移误差和沿着这三个方向的线位移误差的影响,采用一种基于三维模型的数字化方法对这些几何误差进行分析。通过参考坐标系和齐次变换矩阵建立二维直线运动平台几何误差运动学模型,并基于误差模型对运动平台的各项几何误差进行分配、计算和合成。基于以上误差分配原则对运动平台使用的导轨提出形位公差要求。通过上述工作,在虚拟样机设计阶段能对所设计结构几何误差进行预测,为后续精密运动的设计提供可靠的参考
