#AFG under the #Taliban rule:
1. TB prevented girls from entering Kabul university because of having colorful veils.
2. TB inaugurated an Aqsa-like symbolic #mosque in a roundabout, in PD5 of Kabul City.
3. U.S. took control of AFG's embassy&consulates in DC, New York&California. ImageImage
“UFN, the U.S. Department of State’s Office of Foreign Missions has assumed sole responsibility for ensuring the protection& preservation of the property of the #Afghan_Embassy or its consular posts in the U.S.,” the U.S. State Department said in a notice.

Stochastic and Deterministic LGD Loss Given Default Models are different.
Many bankers are unable to understand the different mathematical assumptions that can make the computations.
That is a big risk per se!
@BIS_org

What is a hazard rate assumption?
How can credit risk be modelled using hazard rates?
This is beyond an average #banker.
Most primal bankers only understood the 5 or later the 7Cs of credit.
Accounting, cashflows, creating a charge on assets, foreclosure, special asset mgmt, etc
Actually, Quantitative Risk Management has not helped at all, in my opinion.
Blindly applying maths and statistics has made decision-making worst.
Banking was about relationship mgmt, business model analysis, accounting trickeries, branch operations, etc
Now it's like a lab work

Going to break-down how easy it is to use #autoML and more specifically JADBio AutoML. If you need an account to try it out, head over to jadbio.com and grab a free Basic plan. Ready? #data #ML (1/16)
STEP 1: You start by creating a Project on JADBio and generating all your study #data. That could either be data that has been processed and normalized by a #Bioinformatician, or public data available in the known data repositories (2/16)
If you’re using software for #molecular diagnosis like our Partner’s @QIAGEN OmicSoft Lands platform, your data is ready to be uploaded on JADBio. #ML 3/16

@ipcc_ch reports that b/w 1971 & 2010, oceans absorbed over 90% of the heat gained by the planet due to #globalwarming. This led to #sealevel rise and has also resulted in higher frequency & intensity of #cyclones worldwide. #ClimateChange #MumbaiMustPrepare @mumbaismagic
Indian Ocean has also warmed but what is worrying is the higher rate of #warming in comparison to other global ocean basins. Data shows that Indian Ocean’s rapid basin-wide warming of ~1degC over the last 60 yrs exceeds that of the global average of ~0.7 degC. #MumbaiMustPrepare
Arabian Sea & Bay of Bengal have also seen consistent warming in past decades. The trend in rise in sea surface temperature for BoB has been 0.16C/decade & 0.18C/decade for AS. Arabian Sea indeed has been warming quite rapidly and impacts are for us to see. #MumbaiMustPrepare

Mar 9 2021: "#COVID19 has turbocharged normal market forces" w/ #mRNA as "shiny new object" in world of #vaccines & #biotech. With "unprecedented public funding", biotech stocks soar in tandem w/ corporate profits w/ citizens as experimental subjects.

"They (corporations) will only invest once the #market & the chances of success are well known. This doesn't mean there's zero risk. But largely, what we see is that the #PublicSector takes on most of that. But indeed, this is what allows the business of #vaccines to operate."
#PPP: Public💰$ foots bill, owns risk.
Private💰claims ownership/profits.

"#PublicSector, govts collectively, [] de-risked & subsidised the R&D process every step of the way from [] earliest stages of R&D, oftentimes to the scale up of manufacturing &, of course, purchasing."

I am humbled and privilleged to note that my #Research paper; "Sources of #Unemployment in #Lesotho" is now available and can be accessed via the People's Republic of #China's National #Science and #Technology #Library - #NSTL. I give thanks 😎 Image
So far this year, I have successfully published three #Research articles in #Macroeconomics & #Finance, with another two in press. I am currently hammering away at a handful of working papers which will most certainly find a home in reputable #Journals, come 2021 🙏🏽🙂 Image
Im currently internalising the very insightful reviewer comments on my latest #Research paper titled; "Investigating Determinants of Commercial Bank Spreads in #Lesotho", from the good folks over at the globally reputable #International #Journal of #Finance & #Economics #IJFE 😊 ImageImage

1/ I ran a course on applied financial #modeling for #credit relationship managers last week.

In the day and age of #models, do #analysts still need to understand how models are put together and numbers projected.

Credit systems give us numbers. Do we need more?
#banking #risk
2/ To translate model figures into useful insights, an analyst must understand what drives a business and how those drivers would be impacted by future outlook.

A model is only as good as the input we plug in. Without relevant insight good models also produce garbage
3/ For instance, how would remote learning impact margins at school systems? Would enrollment numbers go up or down? How about non-core expenses?

When a senior #credit committee member asks a question or challenges an assumption, you can't hide behind the #model.

Indebted to the very ideology of communism and not #China. Not only there in China, but one may find it in capitalist #US, #CzechRepublic, #Guinea and even in #Nepal as well, which was celebrated to be a #Hindu nation by the sanghis themselves in the quite recent past.
No one can find even a vestige of #SanghParivar when one seek for it outside India and that's the very reason why the global homosapiens could not get in to solidarity with it. Those can set aside their impression that communists can be targeted in the space of the current
tension. The 56 inch - gauged - chest will also be questioned and audaciously reprehended. The unparalleled and squeamish thing in between is all the neighbouring countries have now turned against us. It's not #Pinarayi Vijayan who visited china more than 6 times within such

Tonight I'm going to share highlights from the 2010 "Scenarios for the Future of Technology & Int'l Development" report produced by The Rockefeller Foundation & Global Business Network. Not just the "Lock Step" scenario, but all 4 scenarios. [54 page report]
Following Event 201 (Oct 18 2019), we must concede that the ruling class has been gifted with phenomenal and prophetic intuitions & insights. (They truly are the chosen ones.) Thus it is worthwhile, even mandatory, to study their scenario exercises & simulations.

A thread to cover some of the major - and I mean seriously, shockingly major - gaps, mistakes and problems with the #environmental impact assessment for Montijo airport in #Portugal.

First up: no #fieldwork. AT ALL. 1/
That's right – the EIA of a major international #airport proposed for the country’s most important #wetland site for #bird #conservation didn’t bother to actually count any #birds.

Instead, they depended on studies already published for other reasons.

How did that work out? 2/
Well, the data on birds feeding in the #intertidal- the largest and most important #habitat in the #SPA- was collected in 2002-3.

In the 17 years since, the #Tagus has changed a lot for birds. Improved #water treatment but drastic increase in #shellfish harvesting. 3/

(Thread) Here is a short summary of "Rules of ML" by Martin Zinkevich (developers.google.com/machine-learni…). The #MachineLearning life cycle should consist of three phases:
Phase 0
- Launch the product without #MachineLearning . Collect #Data
Phase 1
- Building the first basic/transparent #model
- Make the #infrastructure right
- Monitor the right set of #metrics
- System should get a boost with a simple model itself
Phase 2
- More #FeatureEngineering on top of simple model (Low hanging fruits). #Regularization.
- Multiple launches with new features
- Metrics should still be rising with each launch
