Dealing with Student Deceptions: What to do with 'Death in the Family' Excuses

Increased demand for cobalt can be a GOOD thing. If governments enforce existing legislation restricting the use of conflict minerals, mines and smelters in the DRC that do treat and pay their workers fairly will thrive.

http://www.responsiblemineralsinitiative.org/minerals-due-diligence/cobalt/

However, if you look at the legally-mandated Conflict Mineral reports of many publicly-traded US companies, they currently say that the companies do not KNOW that any of their materials are illegally produced (not that they know that all of their materials are legally produced). The difference is like "I didn't actually see anyone poop on your food, but I deliberately kept my eyes closed" vs "Your food was produced in a poop-free kitchen".

The problem is that sometimes when students lie about a death in the family, its because they have a real valid reason for an extension that they are ashamed of admitting -

eg

- surviving a sexual assault
- domestic violence
- suicidal depression
- homelessness...

I asked for extensions on papers a couple of times at university. I didn't have any particular reason, just needed more time, but it never occurred to me to invent an excuse. All my grandparents were still alive then, but I'd have had a better chance than the average person of needing to attend a funeral, as I had not four but six grandparents, due to a divorce and remarriages.

Dealing with Student Deceptions: What to do with 'Death in the Family' Excuses

Given that the author notes that these excuses spike around major holidays, I would have thought the easier, more compassionate answer is to stop assigning work that's due around major holidays, but what do I know?

I love the comic relief in the latest Moonfall trailer, but my hope is that the comic relief is not the result of reshoots and that they didn't just put all the jokes in the movie in the trailer.

One way to deal with the electric battery supply problem is by not putting such big batteries in cars and having the roads electrified. This seems to be working...

There seems to be so many advantages to this! Less batteries in cars means less weight on the roads and so lower road maintenance, and you wouldn't have to remember to charge your car at home. So unless there's some technical reason for this to not take off, (such as not being able to pick up a charge at highway speeds), it just has to catch on (in the more socialist countries of the world).

I don't find this nearly as comforting as the Dr.

To be on high alert (even if you perform better) may mean on that individual test you function well, but your dopamine and norepinephrine is getting pumped. That will lead, if a constant pressure is given, to a downregulation and ... well... (Back to step 1). Short term gains in productivity may exist, but there is a longer term cost.

So I think both Hariri may be disingenuous, but the doctor is also either purposely lying by omissions or so focused on that detail that he's not considering other possible factors or issues.

IDK. I think there's something going on with this all. But I don't think you can just blame it on "the internet" or "cell phones" - but there's some sort of multiplication factor that converges a variety of forces.

(Also - neurochemistry alone isn't so clear cut so even my dopamine downregulation statement is partially loaded and has a lot of hidden assumptions, that apparently, according to Dr Robert Sapolsky are not necessarily true and way more simplified than the complexity underlying the human brain).
