AKA cite your sources.

Something the russian party has no idea means, since they go all by feeling.

I (initially) got a zero on a lab report senior year because I copied and pasted my own calculations section from the previous lab report. I was told it was plagiarism and I needed to cite it. I asked if the dean would agree with the professor.

Denver University now uses TurnItIn, software that compares your paper with scholarly articles and gives you a score. My last paper got a 38%, so I was allowed to submit, but received a nice lecture on paraphrasing instead of direct quoting. Even with the APA f ups, I got a perfect score.

dx,

That is a common policy. It makes little to no logical sense but I have heard of it quite often actually.

When I was teaching the students had to hand in documentation for physical exams. Well, if you did it right most of it was tagged as like someone else's :rolleyes:

"COVID-19: CDC warns that current antibody tests may be inaccurate
New guidance from the US Centers for Disease Control and Prevention suggests that in areas where the prevalence of COVID-19 is low, “less than half of those testing positive will truly have antibodies.” The CDC also says that antibodies are not accurate enough to use to make important policy decisions. "

Weird...
I'm a little concerned about the antibody test results Cuomo is touting. First, I don't know a lot about antibody testing but I would be very cautious if they exclude a couple things:
1. Specificity of the tests (essentially gives the number of false positives). This is especially important given that we don't seem to know if someone who had a different coronavirus that's essentially harmless but has not been infected by COVID-19 could give a positive result on these tests.
2. How they selected the samples
3. A caution that a positive test result doesn't mean you're immune, even if it's not a false positive. We don't know that yet. We can predict, but we don't know.
4. Relatedly, if the false positive rate is fairly high, that's... not good.
5. How did they process the data.
6. Whether they are using resolved cases that correspond to the sampling dates to determine any kind of fatality rate


Regarding point 4, there's a great short video from Pro Publica (I really, really need to subscribe/donate to them) that helps explain why proportion of FP to total positives is important:

@propublica
In some situations, antibody tests generate more false positives than real ones. It’s because of ... math. Here's what you need to know.

For point 5, here's a fairly good but dense thread on why there are some issues with the studies coming out of Santa Clara right now and why they might be important for the NY testing results.

The statistical analysis in the Bendavid et al. revision still seems to have at least one fatal bug.https://www.medrxiv.org/content/10.1101/2020.04.14.20062463v2.full.pdf

DU just went to it. Last quarter, I was marked down a lot for poor APA formatting, but this quarter, I'm actually being graded on content. That said, I've been citing my sources a lot, so I don't know why TurnItIn even matters.

So, who f-cked up?

Completely biased assumptions:

1. Incompetent GOP apparatchiks understaffed/underfunded labs and got crap results.

2. Cynical GOP politicals rushed and/or flat out lied and screwed up the science.

3. Profit-driven medicine, stripped of government oversight, delivers another kiss of capitalist death.

The aerosol filtering efficiency of different materials, thicknesses, and layers used in properly fitted homemade masks was recently found to be similar to that of the medical masks that were tested
Cited source: https://pubmed.ncbi.nlm.nih.gov/32329337/?dopt=Abstract
The emergence of a pandemic affecting the respiratory system can result in a significant demand for face masks. This includes the use of cloth masks by large sections of the public, as can be seen during the current global spread of COVID-19. However, there is limited knowledge available on the performance of various commonly available fabrics used in cloth masks. Importantly, there is a need to evaluate filtration efficiencies as a function of aerosol particulate sizes in the 10 nm to 10 μm range, which is particularly relevant for respiratory virus transmission. We have carried out these studies for several common fabrics including cotton, silk, chiffon, flannel, various synthetics, and their combinations. Although the filtration efficiencies for various fabrics when a single layer was used ranged from 5 to 80% and 5 to 95% for particle sizes of <300 nm and >300 nm, respectively, the efficiencies improved when multiple layers were used and when using a specific combination of different fabrics. Filtration efficiencies of the hybrids (such as cotton-silk, cotton-chiffon, cotton-flannel) was >80% (for particles <300 nm) and >90% (for particles >300 nm). We speculate that the enhanced performance of the hybrids is likely due to the combined effect of mechanical and electrostatic-based filtration. Cotton, the most widely used material for cloth masks performs better at higher weave densities (i.e., thread count) and can make a significant difference in filtration efficiencies. Our studies also imply that gaps (as caused by an improper fit of the mask) can result in over a 60% decrease in the filtration efficiency, implying the need for future cloth mask design studies to take into account issues of "fit" and leakage, while allowing the exhaled air to vent efficiently. Overall, we find that combinations of various commonly available fabrics used in cloth masks can potentially provide significant protection against the transmission of aerosol particles.

Well, when you pull it out on lab 2 for copying lab 1...

It's dumb. Don't give someone a zero on 12% of someone's total final grade without making sure they understand it first.

I agree. When someone explained it to me once I literally got a headache and told them to stop. That is a lazy teacher.

Well, they keep changing their recommendations, so like what do we know to believe? Therefore, I'm not going to wear any masks or follow any guidelines. Isn't that how it works Rube?

As an undergrad I was called into a meeting with a bio professor because they felt a draft of my term paper was "plagiarized." I was told the methods scored too high on some stupid metric. I pointed out that they are specific to my lab, published by my lab, and I cited in my paper... my labs prior publications. They insisted I had to change around the wording because of a vague score the which they would not give me more information. I eventually did change it because I was just an undergrad and had no power or say.

I brought the "revised" draft back to my PI (30+ year professor, helped map our understanding of the visual cortex) and he lost his ****. He took care of that nonsense with one phone call. I have not had a similar issue beyond undergrad nonsense.

102,000 Americans dead. The equivalent of a home game at Ohio State in October. Gone.

A 9/11 a day for 35 straight days.
