Hello. My activities on Wikipedia split into professional and recreational spheres. At work, I'm a Senior Lecturer in health informatics (work website here), specialising in consumer health informatics, which includes research on Wikipedia.
This study, by User:Hydra Rain and I, used a questionnaire and interviews with individuals who had edited a random sample of health-related articles on Wikipedia. It was published in 2014 as Farič N, Potts H (2014-12-03). "Motivations for Contributing to Health-Related Articles on Wikipedia: An Interview Study". Journal of Medical Internet Research. 16 (12): e260. doi:10.2196/jmir.3569. ISSN 1438-8871. A conference paper was presented in the previous year as Faric, Nusa, Potts, Henry. "Motivations for Contributing to Health-Related Articles on Wikipedia: An Interview Study". Retrieved 16 June 2014.
While I am very interested as a researcher in health-related topics on Wikipedia, I haven't done a lot of editing in this area. Related to my research, pages I've created include boundary object, threshold knowledge, Dr Foster, transmural care, secondary research, forest plot, juvenile osteoporosis, habit formation, Wendy Savage, Hadiza Bawa-Garba case and student selected component. I've also been working on e-health and coproxamol.

I created London Britannia Airport in 2013 and that...
|On 19 November 2013, Did you know? was updated with a fact from the article London Britannia Airport, which you created or substantially expanded. The fact was ... that the proposed London Britannia Airport has been dubbed "Boris island" by the media? The nomination discussion and review may be seen at Template:Did you know nominations/London Britannia Airport. You are welcome to check how many hits the article got while on the front page (here's how, quick check) and it will be added to DYKSTATS if it got over 5,000. If you know of another interesting fact from a recently created article, then please suggest it on the Did you know? talk page.|
Things I'm interested in
I'm also interested in the idea of the Wikipedia:Intensive Care Unit. An important AfD ruling is at Wikipedia:Articles for deletion/University of Florida Taser incident. WP:COI#How to handle conflicts of interest is another important piece of policy around deletion debates: it explicity discourages use of the term "vanity". Useful policy: WP:TPO
I have some interest in the question of whether members of the band of a 'solo act' count as notable, as I think WP:BAND provides insufficient guidance on this point. I suggest that a regular member of a solo act's band should count the same as a regular member of any other band. Three past AfDs that are relevant here are: Wikipedia:Articles for deletion/Barney James, Wikipedia:Articles for deletion/Del Palmer (second nomination), Wikipedia:Articles for deletion/Evan Taubenfeld.

Notes on 'margin of error' in opinion polls
The following notes were inspired by a discussion on Opinion polling for the next United Kingdom general election, but I am including them here for potential more general usage.
Margin of error is a familiar term in opinion polling, but often a misunderstood one. Statisticians usually talk about a related concept, the confidence interval. A poll is based on a sample from a population: we use the proportion in the poll supporting party X (or whatever) to estimate the proportion doing so in the population. But that estimate won't be spot on because of sampling error. Assuming we have sampled well (meaning randomly), the sample proportion is an estimate of the population proportion, with the confidence interval/margin of error describing the precision of that estimate. A 95% confidence interval is defined such that the confidence interval for the sample estimate will include the true (population) value 95% of the time. (We can also calculate 99% confidence intervals, or 80% confidence intervals, or whatever, but we usually just use 95%.) The margin of error is then half the confidence interval, so a value may be reported as 40% ± 3% (margin of error), meaning the confidence interval is 37%-43%. This means the true value could be outside that range, but usually (95% of the time), the interval will capture the true value. The only problem is we can't tell from a single poll whether it's one where we were unlucky and the confidence interval doesn't capture the true result.
The precise calculation of confidence intervals is a large topic. However, if we presume a proper sampling technique, for large samples, of large populations, the margin of error for a proportion can be easily calculated: see margin of error for details.
The margin of error and confidence interval vary with the sample size. The details depend on what you are doing, but generally the margin of error is inversely proportional to the square root of the sample size. (Thus, to get half the margin of error, you need four times the sample size.) Most political opinion polls are done on a similar number of people (so as to achieve a suitably small margin of error), but some are bigger or smaller, so you need to see what margin of error is reported for each poll, or do the maths yourself.
The margin of error for a proportion, like vote share, also depends on the vote share. We get better estimates of proportions near 0% and 100% than in the middle. The margin of error is smaller for a party with a vote share of 10% (or 90%) than one on 50%. The margin of error quoted is, thus, usually the maximum margin of error at 50%.
So, consider the following examples. At Opinion polling for the next United Kingdom general election, there is a poll by Survation done on 5 Jan 2013 with a sample of 790 , and another by YouGov done on 5-6 Oct 2011 of 2723 (link broken). We can calculate the maximum margin of error for each of these: for the Survation poll, it is 3.49%, but just 1.88% for the YouGov poll. Remember: not all polls have the same margin of error.
Now let's consider the 21-2 Dec 2011 YouGov poll of 1721 people . This puts the Conservatives on 40% and the Liberal Democrats on 9%. I note the YouGov pdf doesn't even give the margin of error, but we can work it out. Thus, the maximum margin of error is 2.36%, but the margin of error for the Conservative vote is 2.31% and for the Liberal Democrat vote, a mere 1.42%.
With me so far? Good. Because it gets more complicated. Often, we're interested in the difference between two parties, e.g. the lead Labour may have over the Conservatives. We could look at the margin of error for each party, but the margin of error for the difference requires a separate calculation: see Margin of error#Comparing percentages. So, let's take the 18-9 Dec 2011 YouGov poll, again on 1721 people, so we know the maximum margin of error is 2.36%. The Conservatives are on 38% and Labour are on 42%, so the difference between them is 4%, larger than the maximum margin of error. But the margin of error of the difference between the two parties is 4.22%, bigger than the difference between them.
Often, we have more than one poll, at which point we can consider combining multiple polls. When we do that, we're effectively making the sample size bigger, so the margin of error falls. If we have, say, 5 polls within a few days and they all show two parties within the margin of error, the combination of all 5, by reducing the margin of error, may show the two parties as being significantly different. See  and  for details.
This all, of course, presumes the polling was done well. The margin of error only considers the sampling error under certain assumptions. In practice, polls are usually less accurate because of methodological challenges in doing them right: see  for discussion. Some polling strategies appear to be generally more reliable than others. Thus, in the UK, phone polls appear to perform better than online polls.
Useful cite: 
There are many long-standing and deep-rooted issues with Wikipedia coverage of articles pertaining to Doctor Who. I have been guilty of these as well. There is much interesting and entertaining material that would appear better suited to something like the TARDIS wikia, but which does not meet Wikipedia's policy and standards. Here are some developing notes on what I see as the core matters.
- WP:INUNIVERSE: Perhaps the over-riding problem is a (fan) tendency to take an in-universe perspective rather than the out-of-universe perspective required by Wikipedia policy (and there's an associated WP:OR tendency). Egregious examples include the chronology article and the list of Dr Who companions.
- WP:GNG/WP:NOT: There seems to be a sense of entitlement that every spin-off/audio/book must have an article about it, but many of these (particularly the audios, particularly the more peripheral audios) have articles with no links to reliable sources, no content beyond basic production details + plot, and no evidence of notability. Wikipedia is not a list of indiscriminate information. Many of these could be moved to tables in articles describing series.
- WP:RS/WP:V: In the absence of actual reliable source citations, many articles cite fan sources that do not meet WP:RS. At the same time, there is a tendency to privelege the BBC as a source without any support from WP:RS or WP:V (e.g. not wishing to call Jenna Coleman "Jenna" rather than "Jenna-Louise" until the day she is credited so in an episode).
- The Unnatural History syndrome: fans want to put things in neat boxes, regardless that reality and reliable sources don't. For example, the article on people to have played the Doctor feels the need to comprehensively list every occurrence of someone playing the Doctor rather than just saying something like, "Various stuntmen have filled in..." This runs into all sorts of problems with WP:OR and WP:RS.
This article may support a campaign section on 2015 general election article, noting extensive discussion of hung Parliament as possibility and resultant "The Fear" campaigning by the Tories. Plus this. Bondegezou (talk) 22:44, 31 May 2015 (UTC)
