Is the Sample Good Enough? Comparing Data from Twitter's Streaming API with Twitter's Firehose
Data collected using Twitter's sampled API service is compared with data collected using the full, albeit costly, Firehose stream that includes every single published tweet to help researchers and practitioners understand the implications of using the Streaming API.
Simulation modeling in organizational and management research
Simulation modeling provides a powerful methodology for advancing theory and research on complex behaviors and systems, yet it has been embraced more slowly in management than in some associated
Identification of coordination requirements: implications for the Design of collaboration and awareness tools
This work describes a technique for using automatically generated archi-val data to compute coordination requirements, i.e., who must coordinate with whom to get the work done, for the design of collaborative and awareness tools.
Coding Choices for Textual Analysis: A Comparison of Content Analysis and Map Analysis
Coding choices that must be made prior to employing content-analytic procedures are enumerated, as are additional coding choices necessary for employing map- analyzed procedures.
Individual Centrality and Performance in Virtual R&D Groups: An Empirical Study
The study illustrates the usefulness of accounting for network effects for better understanding individual performance in virtual groups by showing that centrality mediates the effects of functional role, status, and communication role on individual performance.
Extracting Team Mental Models Through Textual Analysis
An approach, called map analysis, for extracting, analyzing and combining representations of individual’s mental models as cognitive maps is presented. This textual analysis technique allows the
On the robustness of centrality measures under conditions of imperfect data
Dense networks were the most robust in the face of all kinds of error except edge deletion, which suggests that, for random networks and random error, the authors shall be able to construct confidence intervals around centrality scores.
A Theory of Group Stability
Some groups endure longer, are more stable, and are better able than other groups to incorporate new members or ideas without losing their distinctiveness. I present a simple model of individual
Extracting, Representing, and Analyzing Mental Models
A methodology for representing mental models as maps, extracting these maps from texts, and analyzing and comparing the extracted maps is described, supporting both qualitative and quantitative comparisons of the resulting representations.
Network Structure in Virtual Organizations
It is indicated that the fit between structure and task routineness affects the perception of performance, but may not affect the actual performance of the organization, and existing theories can be expanded to study the structure and perceived performance of virtual organizations.
