Transformer in navigation: Diverse government roles for open innovation in China's high-speed rail

Based on a longitudinal case study of China's high-speed rail embedded in the emerging economy context, we focus on what role the government plays and how that matters to open innovation (OI) for competitive advantage. By linking the OI literature with the national political institutions literature to motivate our research question, we propose a statist-based OI view to differentiate diverse government roles, investigating how government adopts roles in a combined way to push OI in stages. Our findings suggest that government is an important strategic decision-maker for OI. Specifically, the government plays various roles as commander, protector, cultivator, and intermediator, reflecting state activism derived from national political institutions, to construct institutional-level OI for domestic OI activities, and inbound and outbound OI across national borders. We find government can deliberately and strategically use its diverse roles in a combined way to push OI for competitive advantage through the industrial evolutionary process over time. Our study contributes to the OI literature and integrates the strategic management literature with the study of OI to provide new insights to explain the origins of competitive advantage from the state perspective.     

高速SDRAM控制器设计的FPGA实现

同步动态存储器(SDRAM)控制器通常用有限状态机实现,对于一般的设计方法,由于状态数量多,状态转换通常伴随大的组合逻辑而影响运行速度,因此,SDRAM控制器的速度限制了SDRAM存储器的访问速度。该文从结构优化入手来优化方法,利用状态机分解的思想将大型SDRAM控制状态机用若干小的子状态机实现,达到简化逻辑的目的,不仅提高了速度还节省了资源,对该类大型SDRAM控制器的实现有一定参考意义。

Images of transit: the experiential traces of Soviet Jewish emigration

ABSTRACT

Between 1971 and 1990, approximately 185,000 Soviet Jews who immigrated to countries other than Israel traveled through Austria and Italy. This period of transit migration through the “Vienna–Rome pipeline” left deep impressions on most emigrants, as it entailed their first encounter with the West as well as their first steps in their new identity as immigrants. This essay focuses on photography of remnants of the journey – of objects, of old photographs, and of landscapes – in order to explore ideas about immigrants' relationship to the passage of time and their migration experiences. It emphasizes the embodied though often unacknowledged tenor of the past rather than treating it as a distant object of nostalgia. This essay further shows that immigrants draw not only on their experiences in the Soviet Union or the United States to reflect on their lives; the places of transit migration also hold lasting meaning for them.     

Forward,Ever Forward: a reading of Robert Harris,Photographic Album of South African Scenery,Port Elizabeth,c.1880–1886

Early copies of the Photographic Album of South African Scenery that was published between c.1880 and c.1888 by Robert Harris in Port Elizabeth consisted of 28 double-card pages with two, occasionally one, tipped-in photographs per page. During the near-decade of its production, the number of images increased, printed captions replaced handwritten captions and both the selection and arrangement of images became gradually more coherent and programmatic. The paper interprets these changes as Robert Harris’s attempt to construct a public identity for South Africa at the moment its economy and society were being transformed by the diamond mines at Kimberley and elsewhere that constitute the focus of the later form of the form Album. In the developed form of the Album, a narrative progression is suggested to move from Cape Town and the Western Province, to Port Elizabeth and the Eastern Province, to the Kimberley Diamond Fields, Natal, etc. In order to read this journey critically, the paper is arranged to demonstrate the constituent parts of this journey in the representation of cities and towns, laid out in grid plans on the African veld; the depiction of individual buildings with their expressive vocabulary of architectural style; and the idea of commerce – represented in street scenes, markets and seaports – and the facilitation of commerce through roads, bridges and mountain passes. The disproportionately large number of photographs of Kimberley, with both its mining operations and no less than three commercial markets, underlines the significance of commerce and industry in the new South African identity. The emphasis on commercial achievement in the Album leaves an obviously subordinate role for images of nature in both agriculture and landscape. Farming is represented through such exploitative practices as forest clearing and hunting, rather than the developed forms of agriculture of wine farming, sheep farming and wheat farming. And landscape in the Album is either a landscape subdued to the wants and needs of a settler population that would bludgeon its way through mountain passes or divert the course of rivers to facilitate commerce, or a landscape that is defined by the imported aesthetic conventions of the picturesque and sublime. Similarly, grouping the photographs of indigenous peoples that are scattered throughout the Album, one may see that their representation is entirely instrumental, divided crudely into roles of either war-like barbarians or pliant labourers. In these ways, the Photographic Album may be understood as a true mirror of the colonial achievement.

Stereoscopic visions: reading colonial and contemporary African photography

This piece argues for the importance of critical engagements with photographs in order to explore and rethink the past, to reflect on the present and to imagine the future. It provides a brief overview of the articles that constitute the first part of the Social Dynamics special issue on photography in Africa, a collection that contributes to the growing body of scholarship that deepens our understandings of the significance of photography on the continent.

From salons to the native reserve: reformulating the “native question” through pictorial photography in 1950s South Africa

The article provides a critical reflection on the practice of photographic salon exhibitions in the 1950s. In South Africa and abroad, there was a resurgence of photographic societies from the early 1950s that encouraged amateur photographers to create images based on a distinct visual grammar, thereby offering them not only an opportunity to display their work but to compete amongst each other. Subsequently, salon exhibitions produced work that would be judged on its pictorial rather than strict representational value thereby depoliticising the exhibition space. On the other hand, this article seeks to place this practice in the realm of racial segregation under apartheid by considering the deployment of the “black subject” in the native rural reserve in Joseph Denfield’s (1911–1967) work. Through a study of his ethnographic photographs which were exhibited internationally in this period as pictorial work, as well as his intellectualisation of his practice as native photography, it argues that the space of the salon allowed him to pose the “native question” pictorially, that is, provided a discourse through which the “native” could be “known” and ordered.
