There's very unsettling news at @MountSinaiNYC, and I'm going to write a long thread about it.

With it, I plan to share a relevant experience I've never publicly discussed and I will offer ideas of action steps.

I hope you'll to read this thread, share what's happened, and act.
You should read this if you care about honesty and treating people decently.

You should read this if you worked or trained at @MountSinaiNYC.

2 de mayo. Hace justo hoy tres años que el Leicester City, en su segunda temporada en la Premier tras diez años en segunda, se proclamaba campeón. Claro que merece un hilo, porque la ciencia de datos fue clave en ese hito. #datascience #datasports #sportscience
El Leicester City #lcfc ascendió tras la temporada 2013-2014, en la que arrasó en la English Football League, la 2ª división del fútbol inglés. El año anterior se había quedado fuera en el llamado “minuto loco”.
En esa temporada 2014-2015, el Leicester City #lcfc estuvo a punto de descender, lo que no hubiese sorprendido a nadie. A falta de 6 jornadas era último. Acabó 14º tras una espectacular racha de 6 victorias en 7 partidos.

So I heard about a really bad take today, that things that are available free online aren't good enough to be worth money.

To counteract that rubbish call, here I tender a list of free, online #rstats books that I recommend above paid ones #OER
1/many
This list (of course) begins with @djnavarro's Learning statistics with R. Want a brilliant, approachable entry to both statistics and #rstats when you have no prior background, I can recommend nothing else.
learningstatisticswithr.com/book/
Got less of a psych focus and coming from a #DataScience angle, well you must read @hadleywickham & @StatGarrett's #R4DS. It has it's own supportive community (@R4DScommunity) that you should check out also.

DataCamp quietly published a "community" post today, in which they admit an executive sexually assaulted ("uninvited physical contact") an employee. datacamp.com/community/blog… #Python #rstats #datascience #MeToo
this post is nauseating. it can barely bother to be contrite. missing from the list of actions the company has taken are:
- any consequences for the perpetrator/executive
- anything the company has done to make things right for the employee.

#Python #rstats #datascience #MeToo
when a male tech executive (unless i'm mistaken, all of DataCamp's executives in October 2017 were male) abuses an employee, he gets a personal coach. what does the employee get?

Hello #BIWisdom tribe, and welcome to our weekly discussion.
This week on #BIWisdom I’m excited to discuss #skills for #data and #Analytics.
This is a favorite #BIWisdom topic of mine, because prior to my #Analytics journey I was a teacher in the UK. I’ve written about it a little on LinkedIn linkedin.com/pulse/positive…

Racism is not just a set of discriminatory actions; racism (and racial capitalism) is hardwired into very #infrastructures of our daily lives, shaping who breezes through life with clean, potable water and who lives without ‘universal’ public services. A thread.
In the Annals of @theAAG, @shiloh_deitz and I explore domestic water provision in the USA and expose its racialized, classed, and political nature. Yep, we do the entire country. We run the @ipums numbers. We make the maps. We bring the facts. tandfonline.com/doi/full/10.10…
Myth: Public water service is 100% universal in the USA. Fact: Nearly 1.5 million occupied households the US lack complete plumbing (water + sewerage) in their homes. That’s equivalent to the nation’s fifth largest city. A city of the plumbing poor. #waterinsecurity

You going to Health Datapalooza next month? YOU WANT TO, you do! It's never just a nerd herd, and this year you'll get #cyberwoke. Settle in, I'll spin the tale. #HDPalooza #epatient #datarights

Last month a friend asked me "what's the best resource you've read thus far on human decision-making?" 1/
After thinking about it, I decided to recommend her one of the first such resources I ever encountered, seven years ago: Doug Hubbard (@hubbardaie)'s How to Measure Anything. 2/ amazon.com/How-Measure-An…
While I don't agree with every word of it, How to Measure Anything is quite possibly the most important and useful book I've ever read on any topic. Here's why. 3/

Hello all #dataviz fanatics! It’s time to kick off our #datavizbook #epibookclub for @kjhealy’s new book, Data Visualization.

Remember, if your book hasn’t arrived yet or you’re waiting on the library, you can read it here: socviz.co

#epitwitter #datascience
This week, we’re reading the Preface and Chapter 1: Look at Data.

I’ll post some highlights from each and then I hope you’ll chime in with your thoughts, comments, questions, etc.
In the Preface we get a nice overview of the goal of this book: the why and how of good data visualization for beginners, including practical applications in R with ggplot2.

The book doesn’t assume any prior knowledge of R, & covers everything #dataviz from scatterplots to maps.

Also: Retweeting this in order to avoid spamming this thread and getting blocked again. I will continue here. @woonomic
What a mess.. I just noticed that most of the tweets do not seem to be viewable from the outside -but only for myself- due to the autoblock. Copy paste below in order to create a coherent structure/thread.

Hoping this does not happen again when I write everything on my own wall.
Related to your claim that [M = PQ/Vu + I/Vi].

First issue: Why do you over complicate things by splitting up the 'utility economy' and 'investment economy' when you're interested in the aggregate network valuation?

#CSPC2018 now at the participatory panel on funding for trainees.
Most voted model for support for trainees is direct via scholarship and fellowships (rather than thru institutions or via grants), and 52% prefer higher value to 48% wanting more awards. #CSPC2018

These are some of many questions in @DSP_SPE survey 📎 sp-exchange.ca/events/survey/

Saturday Keynote at #ODSCWest Carrie Grimes Bostock - Data Science & Automated Decision Making. Automation has inputs, model(s) and potential outputs for action.
What is the goal of your models? Interpretability is important, but not the only thing. Other measures exist, but understanding your model is important to prevent outcomes, override recommendations, and to connect models to other systems - or stacks of models & systems. #ODSCWest
Example: placing racks in the Santa Clara data centre. Considerations, restrictions on space, power, future use of space, etc. Also: People install racks. They need to be able to intervene based on info that the placement model doesn't have. #ODSCWest

Next up: Katie Malone @multiarmbandit From Presidential campaign trail to Enterprise - Building a #DataScience team @CivisAnalytics
Effective #data-driven teams: different in existing organizations than start-ups. Need to find the best places to build in data value without overturning everything else. Challenges: personal-level analytics, resource allocation, security, privacy. #ODSCWest
Business & data teams will see problems differently. Data teams need to be comfortable with trade-offs in business. Metrics can be ill-defined. Speed can be better than perfection. Important to understand adequate accuracy of models. #ODSCWest Oh yeah, and security.

Now up: Zachary Brown, Lead Data Scientist at S&P Global on #DataScience and #OpenEducation for the enterprise. Dayjob: #AI, Sidehustle: building #digital skills using #opensource #ODSCWest @School_GC
#DigitalLiteracy - Why? Effective work today requires a lot of associated learning. @linuxfoundation @github #VersionControl #Visualization -- continuous learning is critical. Optimal tools & processes are probably not the ones you are using now (Matlab vs. Scikit-Learn)
Need an evolving understanding for what tools are available today to get your work done. If you want your business people to work with your #datascience team, they need to understand what data is and what it can do. Also helps to avoid chasing buzzwords and bling.

Thread: Building an ethical foundation for the AI-driven future @PeriscopeData
First question: What value do you bring to your org. as a data professional? #techskills #businessoutcomes -- likely responses. Then Facebook & #unintendedoutcomes #ODSCWest
Industry starting to confront #ethics in terms of daily applications of #AI algorithms. #Bias based on data - in the case of courts, potentially hundreds of years of biased decisions as part of the training set.
"I'm just an engineer" not an appropriate response. People using #AI products might not understand what or how decisions and predictions are being made, but will be making real world decisions based on them. YOU and your team might be the only ones who do.

#AI differential - being able to tailor products to specific users == better able to predict value to and from users. E.g. cost to deliver value to user vs. cost to company to deliver that value. Allows ruthless competitive focus - @DataRobot #ODSCWest

The top scoring Gab post mentioning "jews":

"For all of you who are new to Gab, don't worry about the racism. I know it can be a little weird at first, but pretty soon you're going to realize that racism is normal and the only reason you haven't ...
... seen it before is because the Jews were censoring it."

“How does #ux work with #agile” ?

Step 1: Read the Agile Manifesto for Software Development agilemanifesto.org

Step 2: Read the Principles behind the Agile Manifesto: agilemanifesto.org/principles.html

Step 3: For a modern twist, check out Modern Agile: modernagile.org

1/3
...you’ll quickly notice there is no mention of Product Owners, Sprints, User Stories, Story Points, Scrum Masters, Demos, Jira, etc. And no mention of #ux, #datascience, #businessanalyts #devops etc.

There is one key thing though... 2/3
Try as hard as possible to join a team as an equal member. The team is the unit of self-organization and inspect/adapt. Do the #agile thing and experiment with how to make #ux work in context. Harness agility to do great #UX

That’s it. 3/3
