## Site / tool to contact multiple study participants with their IDs after pseudonymization

For this multiple-weeks research study with an early access app, a pseudonymization process is used to disconnect the participant’s emails from their data with a random ID.

I need to contact those people after they registered through the pre-form and provide them with the app link and their ID. They will need it to fill out the post-form and provide the ID so the data of this second form can be connected to the data of the first.

Now the thing is that I have about 60 people and it would be annoying to send each of them an individual mail with their ID.
Can anyone recommend something that would make this easier?
To somehow automate the process of sending out the correct ID to the correct email?

I’ve thought about tools like Mailchimp, but you can only dynamically reference variables that the user provided (e.g. name or gender).

## Australia Graduate Visa Post-Study Work stream study documents with credit exemption

I’m applying for a Graduate Visa in Australia (Post-Study Work stream). I understand that the study requirements is 2 years.

My education condition is as following:

1. I studied master degree in 1.5 years (I got credit for a semester because of my bachelor degree)
2. I studied bachelor degree in 1 year

Both studies are in Australia.

My question:

When I apply for Graduate Visa Post-Study Work stream, do I need to include both my bachelor and master transcripts?

## Which visa is applicable to be me? Visitor or Short Student Study Visa

I am in the Yacht sailing fields and currently finished my first season (10 months) here in India. I saved some money to take up a short competent crew course with RYA (Royal Yachting Association UK). The courses are conducted by UKSA which is accredited to BAC. I am also a member of RYA.

Its a recreation course of 7 day duration which includes 5 days and 5 night practical on the boat includes food and accommodation on the boat. 2 days on site for the oral exam for which food and accommodation are included in the course fee.

There is also a boat show organized by RYA in Uk which coincides with my course and it’s in the same region and I also keen on visiting this show. I have a complimentary ticket for this. The course starts from 6-13 September 2019 and the boat show is from 13-22 September 2019. My main purpose is to get the course done so that the certificate will help me for promotion and finding a better opportunity here in India. I have a RYA Powerboat certificate which I did in Thailand. I also have Radio Operator Certificate GMDSS issued by MCA UK.

Looking at the above situation can anyone tell me which visa is applicable to me. Visitor Visa or Short Term Student Study Visa my main purpose of the visit is for the course.

## Estimate variance in a nested study design

I have a “mother” bacteria. I cloned it $$R$$ times and measured a variable $$P$$ on these $$R$$ clones and recorded the mean $$\bar p$$ and the variance $$V$$ among these clones.

Then, I made $$M$$ mutants ($$M$$ new bacterias each carrying a single new mutation) from the “mother bacteria”. I cloned each of these $$M$$ mutants $$r$$ times and measured the variable $$P$$ again. I recorded the mean $$P_m$$ and variance $$V_m$$ of each mutant $$m$$ ($$1 ≤ m ≤ M$$).

The parameter I would like to estimate is the the mean square differences between the mean value of the “mother bacteria” (estimated as $$\bar p$$) and the mean values of the $$M$$ mutants (estimated as $$\bar P_m$$).

$$\frac{\sum_m^M (\bar P – \bar P_m)^2}{M}$$ would be a biased estimator as I have to remove the variance caused by imprecised estimation of both $$\bar P_m$$ and $$\bar P$$. I think the solution should be along the lines of

$$\frac{\sum_m^M (\bar P – \bar P_m)^2}{M} – \frac{\sum_m^M V_m}{r} – \frac{V}{R}$$

but I am not sure. Can you help me?

## Processing Time for a Canadian Study permit with a late request for a Medical Exam

I submitted my application for a Canadian study permit on the 23rd of March, 2019. I gave in my biometrics which were uploaded to Cic on the 27th of March, 2019. I was requested to give in a medical exam on the 29th of April, 2019.

Initially I had filled out that I did not need one because I was in the UK 5 months prior (back in March) and the application said that if I had not lived in a territory for 6 months or more which required a medical then I was exempted. After I was requested to do a medical exam I got the earliest appointment I could for the 10th of May, 2019. My medical exam was approved on the 16th of May, 2019 and reflected on my Cic portal.

It’s now the 31st of May, 2019 (9.5 weeks after I submitted my application). My processing time was 8 weeks and i’m still stuck on a Background Check. I’m unsure of what my processing time is now, is there some way to have an expected processing time?
