The Development of Social Network Analysis: A Study in the Sociology of Science
TLDR
In this paper, the authors describe the process of centrifugally casting an article such as a tire or the like from a curable or hardenable liquid polymeric material, which process includes the steps of selecting a mold and placing a core within the mold which core is hollow and/or is readily deformable under pressure but which has sufficient memory to resume its original position when the pressure is removed.Abstract:
The process of centrifugally casting an article such as a tire or the like from a curable or hardenable liquid polymeric material, which process includes the steps of selecting a mold and placing a core within the mold which core is hollow and/or is readily deformable under pressure but which has sufficient memory to resume its original position when the pressure is removed. The article being formed is formed between the core and the mold. The space between the core and the mold is filled with the curable liquid material of which the article is to be formed and the hollow core is also filled with a liquid material. The liquid material in the hollow core, the material from which the core is constructed and the curable liquid material all have about the same specific gravity. The mold and core are rotated to centrifugally cast the article which is formed of the curable liquid material. The deformable core permits easy removal from the completed article and the matching of the specific gravities as aforementioned keeps the deformable core from distorting during the centrifugal casting operation. The order of introducing the liquid material into the core, introducing the curable liquid into the space between the mold and core and rotation of the mold and core can be varied within the limits as set forth in the following description. Variations in the structure for accomplishing the principle of matching specific gravities are illustrated and described.read more

Management of data with uncertainties
Christopher Ré,Dan Suciu +1 more
TL;DR: The foundations of query processing and the tools that exists today for managing data rely fundamentally on the assumption that the data is deterministic, but increasingly today organizations or users need to cope directly with uncertain data, either because cleaning it is prohibitively expensive or because it is even impossible to clean.

Multinational Corporate Power, Influence and Responsibility in Global Supply Chains
TL;DR: In this article, a conceptual framework for analysing the extent of power and influence of an MNC in a global supply chain based on a consideration of economic and non-economic exchanges and direct and indirect exchanges in the MNC's industry network is presented.

Network Effects of Demographic Transition
TL;DR: Demographic transition weakens both mechanisms for eliminating free-riders: there are fewer relatives around, and reputation spreads slower, which offers novel interpretations of the origins of legal institutions, the Small World phenomenon, the social impact of urbanisation, and the birds-of-a-feather friendship choice heuristic.

Community Evolution in International Migration Top1 Networks
Mihaela Peres,Helian Xu,Gang Wu +2 more
TL;DR: This study builds top1 destination networks and top1 origin networks in order to understand their skeletal construction and community dynamics and finds that both top1 networks exhibited communities with a clear structure and a surprising evolution, although 80% edges persist between each decade.

Creativity and the Structure of Tourism Destination Networks
TL;DR: In this paper, the authors adopt a social network perspective to analyze a number of destinations whose stakeholders networks are known and compare them to a series of networks made of creative entities and assess the difference.
