I just checked your #2 Dugatkin. I am only able to access the abstract [0] (though interested in the full article as you appear to be quoting from part of it which is not publicly available).
It does not at all represent itself as even taking a specific side on the meaning of "alpha" let alone testify to an academic consensus of any decisive proof one way or the other. It doesn't even have anything to do with the study itself at all.
The line you quoted seems more like an aside. The study was apparently about a simulated game theoretic model, and even refers to the units in the simulation as "combatants". It is an attempt to model and simulate "winner effects" and "loser effects" in tandem over time. It's mostly interested in contrasting this approach with models that only deal with "winner effects" or "loser effects" but not their simultaneous dynamics.
It ends with a modest expression of hope to spur future similar studies and is not even pretending to venture anything like a final definition of "alpha", let alone represent the full weight of academic consensus on that question. Citing it for that purpose feels like drive-by quote mining.
