Going the Wrong Way on a One-Way Street: Centrality in Physics and Biology
When ideas and tools move from one field to another, the movement is generally from the natural to the social sciences. In recent years, however, there has been a major movement in the opposite direction. The idea of centrality and the tools for its measurement were originally developed in the social science field of social network analysis. But currently the concept and tools of centrality are...
متن کاملOne-Way Street Movement vs. Two-Way Street Movement
The Traffic Engineering Department of the City of Fort Wayne recently conducted a before-and-after study of traffic volume trends and speed-delays encountered on the east and west one-way street system now in operation as compared to two-way street movement. This study was confined to the central business district only, as the traffic survey and recommendations were basically confined within th...
متن کاملWrong-Helicity Electrons in Radiative Muon Decay
We have studied in detail the spectrum of the decay μ− → e−ν̄eνμγ as a function of the electron helicity, and verify the prediction [1] that a significant fraction of the electrons in this decay is righthanded. These “wrong-helicity” electrons persist in the limit λ = me/mμ → 0, and are connected with helicity-flip bremsstrahlung in QED. The longitudinal polarization of the electron is calculate...
متن کاملWhen more data steer us wrong: replications with the wrong dependent measure perpetuate erroneous conclusions.
There is a replication crisis in science, to which psychological research has not been immune: Many effects have proven uncomfortably difficult to reproduce. Although the reliability of data is a serious concern, we argue that there is a deeper and more insidious problem in the field: the persistent and dramatic misinterpretation of empirical results that replicate easily and consistently. Usin...
متن کاملDigital Humanities Are a Two-Way Street.
n The History Manifesto, Jo Guldi and David Armitage seek a panacea for what they call short-termism—the shrinking chronological focus of historical studies that leads to the overproduction of micro-histories—in “new” longue durée histories that will rely on big data and on digital humanities.24 We agree that big data and digital humanities offer new and valuable ways of making history, includi...
