The first time this has happened to me, but I had three really engaged and constructive reviewers for one of the papers for my #PhD.
My faith in the peer-review system has been (momentarily) restored

Adicionalmente, yo hice este feed que busca palabras claves de temas de transporte. No es perfecto, pero es un buen punto para empezar bsky.app/profile/did:...

If I hear a single American saying "but this is not who we are", I'm going to lose it

"In recent years, I’ve often wondered if Trump has changed America or revealed it. I decided that it was both — that he changed the country by revealing it. [Now] I’m considering an addendum: Trump has changed us by revealing how normal, how truly American, he is." www.nytimes.com/2024/11/06/o...

"Vichy Twitter", lol!
Instant classic!

right wingers over on Vichy Twitter are pissed lol

Ben Shapiro
@benshapiro
ABC's moderators are a disgrace to their profession.

Christopher F. Rufo ⚔️
@realchrisrufo
Trump needs to directly challenge the moderators. Say they're in the tank for Kamala. Put them on the defensive.

Hugh Hewitt
@hughhewitt
It is laughable how ABC choreographed this to help VP Harris but it isn’t working because it is so obvious.

Glenn Greenwald

@ggreenwald
David Muir is criticizing and attacking Trump more than Kamala is.

Kamala can relax because the ABC "moderators" are handling the debate for her.

Nice! Could you add me?
I also created a feed a few months ago that parses some keywords and combinations, in case it's useful:

Please sit down before you read this post.

So.

The CEO of Exxon-Mobil just said this in an interview: "We’ve waited too long to open the aperture on the solution sets in terms of what we need, as a society, to start reducing emissions."

There's more... 🧵

Exxon Mobil CEO on the 'dirty secret' of Net Zero: 'People who are generating the emissions need to be aware ... and pay the price'

"The dirty secret nobody talks about is how much all this is going to cost and who's willing to pay for it," Darren Woods said on Fortune’s Leadership Next podcast.

Right? Protected bikelanes would absolutely solve this problem and they are so inexpensive!

8000 cases and the researcher calls this "a really significant public health problem,"

You know what's a real health problem?

"Traumatic brain injuries from motor vehicle crashes were estimated to result in 218,936 emergency department visits, 56,864 hospitalizations, and 16,402 deaths annually."

For some reason, raisin seems like a more appropriate image to me than corn cob.

Sebastian Castellanos @jscastellanos.bsky.social · Jan 17

Surprisingly (at least for me) sustainability and climate change are rarely seen as an objective by cities trying to govern these services.

Sebastian Castellanos @jscastellanos.bsky.social · Jan 17

We uncovered a whole host of reasons: from the public interest of redressing past inequities, to circumstantial motivations such as appeasing the incumbents that have seen their businesses endangered by these new technologies.

Sebastian Castellanos @jscastellanos.bsky.social · Jan 17

In this paper we identified the goals that cities are trying to pursue when managing shared mobility services (like shared scooters and ride hailing).
We then analyzed why they are choosing to pursue these goals.

Decided to go with WCK as someone suggested.

Sebastian Castellanos @jscastellanos.bsky.social · Dec 27

we actually crunched the numbers. You can read about it here: www.wri.org/research/sta...
Electric mobility will be responsible for the bulk of climate pollutant mitigation. Shifting to non-motorized and transit is absolutely needed, but not enough.

Sebastian Castellanos @jscastellanos.bsky.social · Dec 27

I hate cars as much as the next guy (actually more), but this is factually inaccurate.
You are confusing air pollution with climate pollution.
E-mobility (in all its forms, bikes, cars, buses, trucks) is a necessity to avoid the worst impacts of climate change.

Sebastian Castellanos @jscastellanos.bsky.social · Dec 27

yeah, tricky. This is why I was hoping other folks who are better informed than me would have some good suggestions.

Ah, this is great! Going with WCK ! Thank you!

@farhana.bsky.social any specific org you recommend we donate to support Gaza relief?
We've been donating to UNRWA, but wondering if there may be others you know of.

I hadn't used Uber or Lyft in ages and I just had to use them twice this week. They are truly shit now. Incredibly long wait times, ridiculously expensive. Are people still using ridehailing? seems like taxis are a much better option these days.

Sebastian Castellanos @jscastellanos.bsky.social · Dec 6

Yeah! Totally agree with the user-based feed! Learning as I go, so any additional pointers are definitely welcome :)
