Here are some sentences about 'after being'        Schoolgirl awarded €20,000 after being locked in classroom.              Girl dies after being struck by lightning.              Two people die after being swept away by river.        I think we can use 'after being+past participle' when one action immediately follows another action. For example: Girl dies after being struck by lightning.  Here, It means: Girl dies after she was struck by lightning.  Am I correct?  I think I can change 'dies' into 'died'.  For example:     Girl died after being struck by lightning.   Why has 'Girl dies' been written in the news even if she died in past?
What is the difference between the examples below?  Generally, in a newspaper, news is based on past tense (things which have already happened).   Then why are headlines written in ways that says: He Kills (shouldn't it be: He Killed)?  For example:  Parliament passes bill vs. Parliament passed bill  Also  He kills his friend vs. He killed his friend  Please help.
Are the endings "-zation" and "-sation" interchangeable? What is with words that have forms that end both in -zation and -sation, such as localization and localisation?  Many spell checkers recommend -zation. Why is a boolean value in JTable showing as true/false instead of a checkbox? Recently my audio input, from USB headset and USB guitar cable have stopped working. Going into Windows 'Sounds' and enabling 'Listen to this device' outputs the audio as expected; the problem is not with the devices. However, as soon as I try to use them with any other program, discord, for example, no audio input is detected by discord.  I have tried everything I can think of and some suggestions from Googling around;   Updating everything - windows, drivers, all related software Rolling windows back to the last build Trying different USB ports Reinstalling drivers and software Running Windows troubleshooters Playing with device properties settings   But nothing seems to work, any suggestions? How to do something to each file in a directory with a batch script How do you iterate over each file in a directory with a .bat or .cmd file?  For simplicity please provide an answer that just echoes the filename or file path. How do you do Impersonation in .NET? Is there a simple out of the box way to impersonate a user in .NET?  So far I've been using  for all my impersonation requirements.  Is there a better way to do it by using .NET Framework?  I have a user credential set, (username, password, domain name) which represents the identity I need to impersonate. I realize this is probably going to come off as a bit silly, but in Iron Man II how could James Rhodes easily don the Mark II armor that was designed to fit Tony Stark?  As you can see in this image (which isn't an "in universe" shot) Tony and Rhodey are roughly the same height, but it appears that Rhodey has a smaller frame than Tony, which would seem to make for an ill fit of the armor, especially for flight.  This issue could of course have been addressed by the Air Force during the retrofit with Justin Hammer. Ubuntu 17.10 windows' menu in panel I installed the latest version of Ubuntu (17.10) , but the problem is, I can't find the menu bars of applications in the GNOME panel. For instance, the Chrome menu bar doesn't appear on the panel like in Ubuntu 17.04 and earlier versions. I asked a question on Stack Overflow: .

None of the answer given to my question is upvoted and the answer I mentioned is not the oldest one after the bounty started so it won't be awarded by community. What can I do? (except being a good guy and not get suspended :)) Standard deviation of binned observations I have a dataset of sample observations, stored as counts within range bins. e.g.:  min/max  count 40/44    1 45/49    2 50/54    3 55/59    4 70/74    1   Now, finding an estimate of the average from this is pretty straight forward.  Simply use the mean (or median) of each range bin as the observation and the count as a weight and find the weighted average:  $$\bar{x}^* = \frac{1}{\sum_{i=1}^N w_i} \sum_{i=1}^N w_ix_i$$  For my test case, this gives me 53.82.  My question now is, what's the correct method of finding the standard deviation (or variance)?  Through my searching, I've found several answers, but I'm unsure which, if any, is actually appropriate for my dataset.  I was able to find the following formula both  and .  $$s^{2*} = \frac{ \sum_{i=1}^N w_i (x_i - \bar{x}^*)^2 }{ \frac{(M-1)}{M} \sum_{i=1}^N w_i }$$  Which gives a standard deviation of 8.35 for my test case.  However, the Wikipedia article on  gives both the formula:  $$s^{2*} = \frac{ \sum_{i=1}^N w_i}{(\sum_{i=1}^N w_i)^2 - \sum_{i=1}^N w_i^2} \sum_{i=1}^N w_i(x_i-\bar{x}^*)^2$$  and  $$s^{2*} = \frac{1}{(\sum_{i=1}^N w_i) - 1} \sum_{i=1}^N w_i(x_i-\bar{x}^*)^2$$  Which give standard deviations of 8.66 and 7.83, respectively, for my test case.  Update  Thanks to @whuber who suggested looking into Sheppard's Corrections, and your helpful comments related to them.  Unfortunately, I'm having a difficult time understanding the resources I can find about it (and I can't find any good examples).  To recap though, I understand that the following is a biased estimate of variance:  $$s^{2*} = \frac{1}{\sum_{i=1}^N w_i} \sum_{i=1}^N w_i(x_i-\bar{x}^*)^2$$  I also understand that most standard corrections for the bias are for direct random samples of a normal distribution.  Therefore, I see two potential issues for me:   These are binned random samples (which, I'm pretty sure, is where Sheppard's Corrections come in.)  It's unknown whether or not the data is for a normal distribution (thus I'm assuming not, which, I'm pretty sure, invalidates Sheppard's Corrections.)   So, my updated question is; What's the appropriate method for handling the bias imposed by the "simple" weighted standard deviation/variance formula on a non-normal distribution? Most specifically with regards to binned data.  Note: I'm using the following terms:     $s^{2*}$ is the weighted variance   $N$ is the number of observations.  (i.e. the number of bins) $M$ is the number of nonzero weights.  (i.e. the number of bins with counts) $w_i$ are the weights  (i.e. the counts) $x_i$ are the observations.  (i.e. the bin means) $\bar{x}^*$ is the weighted mean. Android App initial release date When you are viewing an app in Google Play store, it displays the following : Updated, Size, Installs, Current Version, Requires Android, and Rating.  I am trying to do some research and figure out the initial release / publish dates of different apps. Is there a way to get this information from Google Play, or perhaps a website with this information? On what site can I ask questions related to copyright? I want to make a summary of a book and use it to earn money. However, I don't know whether it's legal or not.  Which Stack Exchange site can I ask this question on? How to conduct an Accent Sensitive search in MySql I have a MySQL table with utf8 general ci collation. In the table, I can see two entries:  abad abád  I am using a query that looks like this:  SELECT *  FROM `words` WHERE `word` = 'abád'   The query result gives both words:  abad abád  Is there a way to indicate that I only want MySQL to find the accented word? I want the query to only return    abád    I have also tried this query:  SELECT *  FROM `words` WHERE BINARY `word` = 'abád'   It gives me no results. Thank you for the help. How to center text vertically within a textbox in Photoshop It's pretty annoying that you can't center text vertically in Ps automatically, like you can in Indd. It's even more annoying that the bounding box of text can't be 'collapsed' or 'fit to text', like in Indd.  I could convert the text to shape, but then I lose coloring. I could convert to smart object, but then its not vector anymore, for when I export to pdf.  Is there a work around anyone knows of that would make it easier to center text vertically? My daughter asked me to cosign on a car loan.  Somehow I ended up as the borrower and she a the cosigner.  Is that legal? Is it appropriate to use a question mark at the end of a compound sentence where the first independent clause is a question but the second is a statement? For example:     Do you want attribution for that quotation, because I'm definitely sharing it and want to know if I should give you credit?   or      Do you want attribution for that quotation, because I'm definitely sharing it and want to know if I should give you credit.   I suppose this could work, but it's a little niche, as the second clause might not always be appropriate for a parenthetical.     Do you want attribution for that quotation (because I'm definitely sharing it and want to know if I should give you credit)? Why does rubbing feet against sheets create a spark? Sometimes when I'm in bed at night, I rub my feet against the sheets and light is created. What exactly is going on?     I'm familiar with static electricity, and the triboelectric effect (creating a charge by rubbing 2 insulators together), and electrostatic discharge (releasing charge by touching a grounded conductor).     I believe that all of that is what is at work here, but I'm slightly confused since in other cases, the triboelectric effect and electrostatic discharge seem to occur as two separate steps, with different substances involved, and here, the two effects seem to be occurring simultaneously, with the same substances.     Can someone help me with a step-by-step explanation of the dynamics of what is going on? I have a simple question.     over centuries / for centuries   what is the difference?  Thank you. Can a shadow move faster than the speed of light? I'm just a layman with no real science background  (a) I'm not really sure what a shadow is. Some people are saying that it's the absence of something (a photon?) and therefore it is not subject to laws of physics. But I know when I'm in a shadow and when in sunlight... that's "information", and I thought that information flow can't break the speed of light limit.  (b) Some others use the laser pointer/flicking wrist example to talk about laser dots moving faster than light speed. But that can't be right, can it? The photons from the laser point have to travel from A to B and (after wrist flick) from A to C ... but the photons are all moving at the speed of light - there's no law-breaking in moving the laser dot from point B to point C because the photons are moving either from A to B or A to C ... the distance from B to C is not material (is it?).  (c) Also, can a shadow be thought of as a gap in a photon flow? E.g. if I interrupt a beam of single photons then can I think of it as e.g. PPPSSSPPPSSSPPPSSSPPP, etc where P = photons and S(shadow) = no photon &amp;, if so, the "SSS" is effectively travelling at the speed of light ... no faster. I am confused with the grammar here. Which is grammatically correct?       At which time will you call me?     At what time will you call me?    And why? How do I sort custom objects alphabetically in an array in Java?
