Techno-Wizardry and movie magic: the trace of labour (or lack thereof) in 3D digital animation

ABSTRACT

This paper will argue that 3D digital animation, unlike its 2D and stop-motion counterparts, currently lacks recognisable self-reflexive aesthetic devices through which the trace of animators’ labour can be made visible. It will open with a brief history of how animation has previously shown its workings; from the pencil-wielding hand of Émile Cohl to the opening seconds of South Park, plus the intentional and unintentional smears and multiples visible on animation cells. These devices will then be discussed in relation to Marx’s analysis of the commodity in Capital Vol. 1, and how the process of fetishisation is momentarily disrupted by imperfections in the object which have been caused by production errors. These faults reconnect the object to its producer through the trace of (imperfect) labour which remains visible on the surface. In animation, similar (albeit consciously made) ‘errors’ connect the perceptive viewer directly to the work of 2D or stop-motion animators. This paper will argue the need for an equivalent to emerge in 3D digital animation, as well as highlighting some contemporary animators testing and subverting the limits of 3D and sketching some possible ways these might encourage further formal innovations.     

CO-OFDM系统中基于线性预处理的新相位噪声抑制算法

针对相干光正交频分复用（coherent optical orthogonal frequency division multiplexing,CO-OFDM）系统中相位噪声引起的载波间干扰（inter-carrier interference,ICI）问题,提出了一种基于线性预处理的新判决反馈相位噪声抑制算法。该新算法改进了线性预处理部分,利用循环前缀与OFDM符号固有的相关性,在时域进行简单的线性组合运算,充分利用了OFDM符号中冗余信息。仿真分析表明,在激光器线宽为200 kHz且误码率（bit error rate, BER）为10－4时,与判决反馈相位噪声抑制算法和一次迭代的判决反馈相位噪声抑制算法相比,该新算法BER曲线的信噪比（signal to noise ratio,SNR）分别改善了3 dB和1 dB,有效地降低由ICI引起的错误平层。     

‘Back to our Roots?’ Re-visiting psychoanalytically-informed baby and young child observation in the education of student social workers

While there is a well-established literature on psychoanalytically-informed baby and young child observation in social work education, little has been published recently. This paper reviews the rationale for its use, evaluating its impact on students’ learning in the light of contemporary policy and practice contexts facing social work education. Analysis of feedback gained from a recent cohort, identifies three ways in which learning through baby and young child observation contributes: firstly, students encounter and learn about the complexity of child development from the direct experience of observing and secondly, observing facilitates the development of important skills for practice; students’ ‘use of self’. Thirdly, through observing, students describe how they develop the capacity to take-up and sustain a professional role. Well-structured teaching and learning through observation is therefore shown to provide a rigorous, theoretically-grounded contribution to the training of university-based social work students entering this complex and challenging professional field.     

Information society and digital divide in South Africa: results of longitudinal surveys

Integration into the information society implies that information plays an increasingly important role in all sectors of society and holds distinct social and economic benefits. Discourses on the information society are, however, also associated with the digital divide and inequalities in access to and use of information and communication technologies (ICTs). Within sub-Saharan Africa, South Africa is often regarded as one of the most information-integrated societies due to widespread mobile phone ownership, among other things. However, while ICT access has been emphasized, research also points to the role of demographic, socio-economic and cultural factors such as ethnicity, income, education and gender. This article discusses the results of questionnaire surveys conducted by Afrobarometer among probability South African samples in 2008 and 2011. The results indicate that individual Internet use and mobile Internet access were lower than estimated in the literature. Furthermore, gender gaps, as well as considerable gaps between population groups and educational levels, were found in Internet and computer use, mobile ownership and access to mobile Internet and accessing news via the Internet. Conclusions regarding strategies for bridging the digital divide and integrating South Africa into the information society are discussed.     

Curating the Soul: Foucault's concept of hupomnemata and the digital technology of self-care

This paper explores how online actions such as the practice of digital self-writing shape our offline identity. We start with an examination of the concept of hupomnemata – a practice of self-writing in which notes are kept as a ‘material record of things read, heard, or thought’ in the intent of shaping the self [Foucault (1997). Self writing. In P. Rabinow (Ed.), Ethics, subjectivity and truth. The essential works of Foucault, 1954–1984. Volume 1 (pp. 207–222). New York, NY: The New Press p. 209] – before arguing that the practice of digital content curation can be understood as a modern-day variant of the Greco-Roman hupomnemata. Although the work of the digital curator is conducted online, this paper positions contemporary curatorial practices as acts of self-exploration, self-cultivation, and self-care, which nourish offline identity and which ultimately work to shape the offline, corporeal self.

数字时代数字技术崇拜的机制与实质

数字技术崇拜是一种从心理、行为和价值观上深受数字系统影响的社会现象,其特征主要表现为对数字技术及其产品构成的数字系统过于依赖、过度上瘾以及对其塑造的意识形态过度顺服的社会异态关系。这种社会现象的形成主要基于数字化的生存状态,技术理性的迅速扩张和感官系统的极致调动。究其本质,数字技术崇拜背后是经由数字资本逻辑重构社会秩序、数字技术内生意识形态和数字权力塑造单向度人共建而成的机制。面对数字时代人类境遇的遮蔽,并不等于要一刀切地舍弃数据和算法的便利性,而是要唤醒人的数字主体性意识,建立数字权利的政府保障机制和树立正确的数字价值观。     

超大型平台并购初创企业的反垄断法规制研究

超大型平台并购初创企业可能具有反竞争效应,然而在芝加哥学派“假阳性错误”成本大于“假阴性错误”成本的理论观点以及反垄断监管困境的双重影响下,反垄断执法机构对其长期采取宽容的态度。但是芝加哥学派的错误成本理论在应用于超大型平台并购初创企业时存在局限性。频繁实施的初创企业并购非但不会导致超大型平台走向自毁,反将进一步巩固其市场支配地位、抬高市场进入壁垒。即便市场经历漫长期间之后最终完成了自我纠正,规制不足所造成的“假阴性错误”成本也会十分高昂,平台经济领域公平竞争、行业创新发展和消费者权益保护均会受到长期不利影响。因此,在秉持“包容审慎监管”原则的前提下适度加大监管力度,应当成为对超大型平台并购初创企业进行反垄断法规制的基本取向。基于这一取向,未来对超大型平台并购初创企业的反垄断法规制思路需要进行以下调整：以初创企业市值、用户规模、流量规模等补正并购的既有申报标准;确立契合平台经济特点的竞争损害分析框架;针对超大型平台并购初创企业的不同效应建立宽严相济的法律制度;赋予反垄断执法机构更加广泛的证据收集权,强化参与并购经营者的证明责任,并通过结合这二者的方式来化解反垄断执法机构获取监管信息上的...     

我国构建数字经济税收法律制度的现时难题和优化路径

传统税收法律制度在对数字经济企业实施税收征管时存在征管依据缺失、征管技术落后等不足,进而诱发税基侵蚀和利润转移问题,导致无法对数字经济进行充分有效的征管。各国对数字经济的利益诉求不同,使得在国际层面具备广泛共识的数字税方案难以达成。从国内层面来看,我国对于数字经济的税收征管仍旧依靠传统税收模式进行,并未将数字税作为独立税种在法律上予以确认。这种税收模式在数字经济持续发展的当下已经无法满足数字经济税收征管的现实需要。对于当前中国构建数字经济税收法律制度的路径,可以通过升级数字税收监管技术、发挥数字经济平台的监管作用和加强国际税收合作等手段进行优化,并积极参与和推进具有广泛共识的国际数字税收法律规则的制订。
