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

What the eye does not see: visualizations strategies for the data collection of personal networks
TL;DR: The most frequent strategies consist in identifying the key individuals, dividing the personal network in groups and classifying alters in concentric circles of relative importance as discussed by the authors, which facilitates the enumeration of the communities in which individuals participate.

Networks and performance in public organizations: theory, models, and measurement
TL;DR: The authors explored the antecedents of intra-organizational networks and the consequences of network structure on the attitudes and performance of public school teachers in twenty-one schools and found that teacher interpersonal perceptions along eleven salient personality traits were important predictors of network formation.
