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

Collaboration in the events literature: a co-authorship network study
TL;DR: This article examined characteristics of the co-authorship network derived from an examination of the events literature found in major academic journals and databases and found that these clusters are primarily based around particular universities and examination of their location suggests the importance of geography in forming coauthorship linkages.

The financial characteristics of u.s. companies acquired by foreign companies
TL;DR: In this article, the authors compare the financial characteristics of the U.S. companies acquired by foreign companies with a matched sample of non-acquired U. S. companies during the post-crisis period and find that liquidity is not a significant factor in the acquisition decisions of foreign buyers.

Constellations of environmentalism: an exploration of learning and activism within youth-created social media interest groups
TL;DR: In this article, the authors explored how youth in varying geographic locations around the world use social media platforms to engage with their peers in environmental learning and environmental activism, and the results of this multiple case study comprise multiple perspectives from youth from eight different countries, and explore how these affinity spaces foster learning and activism.

Mixing methods and theory to explore web activity
TL;DR: To demonstrate the affordances of this, the activities of the UK Open Government Data community are analyzed by combining quantitative computational science techniques with qualitative social science methods underpinned by social theory, providing a richer and more detailed analysis than either approach alone could offer and one which enables the Web as a complex socio-technical phenomenon.
