MY SILVER MEDAL FROM THE CANADIAN SOCIETY FOR CHEMISTRY – REFLECTIONS AFTER 10 YEARS June 28, 2018 Leave a comment In June, 2008, I received an email from Dr. Ken MacFarlane, then the Undergraduate Advisor in the Department of Chemistry at Simon Fraser University (SFU) . He wrote to inform me that I had won the Canadian Society for Chemistry ‘s Silver Medal, given to the top undergraduate student in chemistry entering their final year of study at each Canadian university. I won the Canadian Society for Chemistry’s Silver Medal for being the top fourth-year student in the Department of Chemistry at Simon Fraser University in 2008. Later in November of that year, I received this medal at a dinner banquet, which honoured all of the award winners from the universities and colleges in the Vancouver Section of the Chemical Institute of Canada (CIC). (Awards were given to the top students in their second year, third year, and fourth year of study.) Here is a photo of me receiving my medal from Dr. Daniel Leznoff; he was then the Chair of the Vancouver Section of the CIC and a professor specializing in inorganic chemistry at SFU. I received the Canadian Society for Chemistry’s Silver Medal from Dr. Daniel Leznoff at a dinner banquet in November, 2008. The CIC publishes a magazine called _Canadian Chemical News_ , and it covered the above award banquet in January, 2009.
You can find a photo of the award winners from that night on Page 29. Dr. Cameron Forde succeeded Dr. MacFarlane as our Undergraduate Advisor in 2009. In an email to me in October, 2009, Dr. Forde wrote that 100-120 students were eligible for the CSC’s Silver Medal in our department in 2008. This is one of the greatest achievements of my life. I am even _more_ excited about it today than I was at that banquet, because I now have 10 years of perspective about how this medal has benefited my career. In this retrospective article, I write to share my reflections about the impact that this medal has had on my professional trajectory – _WHICH HAS BEEN UNUSUAL, TO SAY THELEAST.__

September 24, 2018 2 Comments Today is Monday, September 24, 2018. Suppose that my co-worker Jessica asks me, “Can we meet on next Friday to talk about our report?”. Does she mean * Friday, September 28, 2018? * Friday, October 5, 2018? _Image courtesy of rawpixel.com via Pexels_
The word “next” is tricky to interpret in this situation. By definition, “next” denotes the instance immediately after the present. Thus, “next Friday” _should_ mean Friday, September 28,2018.
However, most Anglophones would interpret this phrase to mean the Friday of the _next week_, which is Friday, October 5, 2018. This is not logical, but it is the dominant interpretation. To prevent this confusion, I avoid saying “next Friday”.Instead, I say
* “the upcoming Friday” to denote Friday, September 28, 2018 * “Friday of next week” to denote Friday, October 5, 2018 These approaches are clear and unequivocal, and they eliminate any chance for confusion. If this is communicated in an email, then I suggest confirming the correct “Friday” by adding the calendar date.
Thus, I would write, “Let’s meet on Friday of next week, October 5, 2018”. This method helps the reader to know if we will meet during this week or next week, and it adds another way to confirm thedate.

COMMUNICATION TIP: WRITE BOTH THE DAY OF THE WEEK AND THE CALENDAR DATE WHEN ORGANIZING MEETINGS OR PLANNING EVENTS September 21, 2018 Leave a comment _Image courtesy of rawpixel.com via Pexels_
When proposing a meeting or planning an event in writing, I STRONGLY SUGGEST STATING BOTH THE DAY OF THE WEEK AND THE CALENDAR DATE. For example, I would email my co-worker Mark, “Shall we visit our client on next Tuesday, September 25?”. Note the contrast between my proposed approach and the following 2alternatives:
* “Shall we visit our client on next Tuesday?” * “Shall we visit our client on September 25?” Some careful comparisons will reveal 3 advantages: * It forces me to check that I wrote the correct pair between the day of the week and the calendar date. This is an extra layer ofquality control.
* If I simply write “Shall we visit our client on September 25?”, then I implicitly force Mark to check what day of the week that is. If I send that email to 10 people, then I’m multiplying this hassle by 10. I can save all parties a lot of headache by taking the initiative to write “Tuesday, September 25”. * Knowing both are very helpful, but often for different reasons. * Knowing the specific calendar date eliminates any source of ambiguity about which day it is. Instead of relying on words/phrases like “tomorrow”, “next Tuesday”, or “the day after”, stating “September 25” is perfectly clear to Mark. * If I propose a meeting on a Wednesday afternoon, Mark may immediately know that it is a bad time, because he needs to coach his daughter’s basketball team on Wednesday afternoons. This illustrates how the day of the week is helpful for coordinating one-time events with events that recur weekly. In the above example, I have omitted the year, because the working context between me and Mark would imply that meeting in September of next year would be rather strange and unrealistic. However, stating the year may be helpful or even necessary for certain situations, especially if legal formality is involved.Filed under Advice

MITCHELL BOGGS ON GAME THEORY IN BEHAVIOURAL ECOLOGY – THE CENTRAL EQUILIBRIUM – EPISODE 8 September 12, 2018 Leave a comment Mitchell Boggs kindly talked about game theory in behavioural ecology on my talk show, “THE CENTRAL EQUILIBRIUM”!
He talked about 2 key examples: * when animals choose to share or fight for food * when parents choose to care for their offspring or seek new mates to produce more offspring These examples illustrate why seemingly disadvantageous behaviours can persist or even dominate in the animal kingdom. Mitch recommends a book called “Are We Smart Enough to Know How Smart Animals Are?” by Frans de Waal. Thanks for being such a great guest, Mitchell! Filed under Mathematics,

COMMUNICATION AND EMAIL TIP: PROPOSE MEETING TIMES IN BOTH TIME ZONES September 4, 2018 Leave a comment When I arrange a phone call with someone in a different time zone, I propose the time in both my time zone and their time zone. _Photo courtesy of Pixabay via Pexels._
This has 2 benefits: 1) I save the recipient’s time and headache from determining what the correct time is for their time zone. 2) The recipient can check if my conversion is correct. On at least 2 occasions, this practice has helped me to identify a mistake in the proposed time of a meeting. Arranging a teleconference via an online calendar invitation solves this problem, because the online calendar will automatically do the conversion. However, not all meetings are arranged this way, so this is still a good practice to adopt.Filed under Advice

PROFESSOR”
August 31, 2018 Leave a comment _Names and details in this blog post have been altered to protect the privacy of its subjects._ In 2014, I wrote about a former professor, Dr. Baker,
who suffered from a chronic liver disorder and endured complications from her liver transplant. I recently heard from Dr. Perez and Dr. Baker about some wonderful news: DR. BAKER JUST EARNED TENURE IN HER JOB AS A PROFESSOR. This required her to get letters of recommendation from researchers in her field. Trusted sources revealed that those letters contained glowing appraisals of Dr. Baker’s work. I was very glad to learn of both this endorsement and the eventual attainment of a treasured milestonefor Dr. Baker.
Besides this professional achievement, Dr. Baker has also improved her health significantly through disciplined care of her health, especially via exercise. I was delighted to learn of this progress. Congratulations, Dr. Baker. Your example shows that perseverance can bring great rewards. I hope that you and Dr. Perez enjoyed your celebratory lunch together.Filed under Advice

DAVID VEITCH ON RATIONAL VS. IRRATIONAL NUMBERS AND COUNTABILITY – THE CENTRAL EQUILIBRIUM – EPISODE 7 August 30, 2018 Leave a comment I am so grateful that David Veitch appeared on my talk show, “THECENTRAL EQUILIBRIUM
“,
to talk about RATIONAL VS. IRRATIONAL NUMBERS. While defining irrational numbers, he proved that is an irrational number. He then talked about the concept of BIJECTIONS while defining COUNTABILITY, and he showed that RATIONAL NUMBERS ARECOUNTABLE.
David used to work as a bond trader for Bank of America. He writes a personal blog , and you can follow him on Twitter (@daveveitch ). He recently earned admission into the Master of Science program in statistics at the University of Toronto , and he will begin that program soon. Congratulations, David!

SOME SAS PROCEDURES (LIKE PROC REG, GLM, ANOVA, SQL, AND IML) END WITH “QUIT;”, NOT “RUN;” August 1, 2018 Leave a comment Most SAS procedures require theRUN;
statement to signal their termination. HOWEVER, THERE ARE SOME NOTABLE EXCEPTIONS TO THIS. I have written about PROC SQLmany times on
my blog, and this procedure requires theQUIT;
statement instead.
IT TURNS OUT THAT THERE IS ANOTHER SET OF STATISTICAL PROCEDURES THAT REQUIRE THE QUIT STATEMENT, AND SOME OF THEM ARE VERY COMMON. They are called _interactive procedures_, and they include PROC REG,
PROC GLM
,
and PROC ANOVA
.
IF YOU END THEM WITH RUN RATHER THAN QUIT, THEN YOU WILL RUN INTO PROBLEMS WITH DISPLAYING FURTHER OUTPUT. For example, if you try to output a data set from one such PROC and end it with the RUN statement, then you will get this error message: ERROR: You cannot open WORK.MYDATA.DATA for input access with record-level control because WORK.MYDATA.DATA is in use by you in resource environmentREG.
WORK.MYDATA cannot be opened. YOU WILL ALSO NOTICE THAT THE PROGRAM EDITOR SAYS “PROC … RUNNING” IN ITS BANNER WHEN YOU END SUCH A PROC WITH RUN RATHER THANQUIT.
I don’t like this exception, but, alas, it does exist. You can find out more about these interactive procedures in SAS Usage Note #37105 . As this note says, the ANOVA, ARIMA, CATMOD, FACTEX, GLM, MODEL, OPTEX, PLAN, and REG procedures are interactive procedures, and they all require the QUIT statement for termination. PROC IML is not mentioned in that usage note, but this procedure also requires the QUIT statement. Rick Wicklinhas written an
article
about this on his blog, The DO Loop.

ARNAB CHAKRABORTY ON THE MONTY HALL PROBLEM AND BAYES’ THEOREM – THE CENTRAL EQUILIBRIUM – EPISODE 6 July 21, 2018 Leave a comment I am pleased to welcome ARNAB CHAKRABORTY back to my talk show, “THECENTRAL EQUILIBRIUM
“,
to talk about THE MONTY HALL PROBLEM AND BAYES’ THEOREM. In this episode, he shows 2 solutions to this classic puzzle in probability, and invokes Bayes’ Theorem for the second solution. If you have not watched Arnab’s first episode on Bayes’ theorem,
then I encourage you to do that first. Marilyn Vos Savant provided a solution to this problem in PARADE Magazine in 1990-1991. Thousands of readers disagreed with her solution and criticized her vehemently (and incorrectly) for her error. Some of these critics were mathematicians! She included some of those replies and provided alternative perspectives that led to the same conclusion. Although I am dismayed by the disrespect that some people showed in their letters to her, I am glad that a magazine column on probability was able to attract so much readership and interest. Arnab and I referred to one of her solutions in our episode. Thank you, Marilyn! Enjoy this episode of “The Central Equilibrium“!

WRITE A PERSONAL MESSAGE WHEN INVITING PEOPLE TO CONNECT ON LINKEDIN July 21, 2018 Leave a comment Strangers send requests to join my network on LinkedIn every week, sometimes every day. When I get such a request, the enclosingmessage is usually
> “Hi Eric, I’d like to join your LinkedIn network.” This is the default message, which means that the sender did not take the time to write a personalized invitation. This is very disappointing, especially because LinkedIn suggests you to write a personal note before sending every request. WHEN YOU DON’T WRITE A PERSONAL MESSAGE, IT SHOWS A LACK OF EFFORT TO ENGAGE WITH THAT PERSON AND DEVELOP A RAPPORT IN THIS NEW CONNECTION. In this age of social media, it is easy and common to add new contacts just for the sake of increasing the size of one’s network, whether it’s “Friends” on Facebook, “Followers” on Twitter, or “Connections” on LinkedIn. ALTHOUGH SOCIAL NETWORKING IS VIRTUAL, CONNECTING WITH PEOPLE IS STILL A HUMAN ENDEAVOUR, AND YOUR EFFORT LEVEL IN THAT ENDEAVOUR WILL REAP PROPORTIONAL RETURNS IN THE LONG TERM. In your personal note, here are possible things to mention: * how you met that person * what you valued in your past professional encounter(s) with thatperson
* what you hope to learn from that person If you accept a thoughtful invitation from someone on LinkedIn, then write a personal message in return to thank them. Either way, read their profiles carefully, and ASK INSIGHTFUL QUESTIONS BASED ON WHAT YOU LEARN FROM THEIR PROFILES. Your new connections will recognize your efforts in noticing their work/education and trying to learn from them, and they will likely appreciate your initiative.Filed under Advice

A TIP ABOUT THE WORD “COLLEGE” TO MY AMERICAN NEIGHBORS WHO WISH TO WORK IN CANADA July 1, 2018 2 Comments Canadian English and American English are very similar, allowing Anglophones in both countries to work and live with ease when crossing the border. However, THERE IS A SUBTLE DIFFERENCE IN OUR VOCABULARIES THAT CAN HAVE BIG CONSEQUENCES FOR JOB SEARCHES AND PROFESSIONAL DEVELOPMENT. To my American neighbours (or neighbors, as it is spelled in the United States of America), I offer this tip to avoid any confusion. IT CONCERNS OUR DIFFERENT USAGES OF THE WORDS “COLLEGE” AND “UNIVERSITY”. The Peace Arch is a monument situated between Blaine, Washington and Surrey, British Columbia. Near this monument is a major border crossing between the USA and Canada. _Image courtesy of RGB2 from Wikimedia._

BEWARE OF ACCIDENTAL REPLACEMENT OF DATA SETS WITH PROC SORT IN SAS June 28, 2018 Leave a commentPROC SORT
is a very useful procedure in SAS. Not only can you sort a data set on one or more variables with it, but you can sort each variable in ascending or descending order, and you can use it to obtain unique observations or duplicated observations.
HOWEVER, THERE IS A FEATURE ABOUT PROC SORT THAT CAN BE DANGEROUS AND DESERVES EMPHASIS: If you are not careful, you can accidentally replace an existing, valuable data set. Suppose that you wish to use PROC SORT to get only the duplicated records of a data set.
Here is an example of how to do it.data heights;
input Name $
Age
Height;
datalines;
Amy 15 174

_Note that the record for “Bob” is gone from HEIGHTS_, because it was a unique observation and, thus, removed in the above PROC SORTstatement.
IF THE ORIGINAL DATA SET IS VALUABLE, THEN THIS LOSS CAN BE VERY DAMAGING, especially if it took a lot of work and time to obtain the original data set. This shows the danger of accidental replacement of a data set in SAS when using PROC SORT. Read more of this post Filed under Data Analysis,

INCLUDE A PROFESSIONAL PHOTO OF YOURSELF IN BUSINESS ATTIRE IN YOURLINKEDIN PROFILE
June 22, 2018 Leave a comment One of the easiest ways to polish your LinkedIn profile is POSTING A PHOTO OF YOURSELF IN BUSINESS ATTIRE. I strongly encourage every LinkedIn user to spend several hours to take at least 100 such photos of yourself. Ask a friend or family member to take these photographs, if they would be so kind and willing to do so. Alternatively, you can hire a professional photographer. After this session, you will have a large stock of photos that you can use forvarious purposes.
Position yourself with many backgrounds, and take those photos from many angles. You should always look straight into the camera, smile, and maintain an upright posture. Here is what my LinkedIn profilelooks like.
When you build a professional network and an online brand, people need to know who you are and what you look like. When they meet you in person, your photo allows them to visually connect you with the online profile that they saw on LinkedIn. This is especially crucial for people with common names; showing your photo allows others to easily distinguish you from others who share your name. It turns out that there is another person named Eric Cai who works as a data scientist! Not only do we share the same name, but we also have the same profession. Without photographs, it would be quite difficult to distinguish between us in a professional setting.COMMON MISTAKES
I recently spoke at the Canadian Statistics Student Conference and at the University of Toronto’s Biostatistics Research Day,
and I talked about this with students at both events. Here are the common mistakes that I see in LinkedIn profile photos, and I URGE YOU TO AVOID ALL OF THEM. * Not having a profile photo * Not wearing professional attire* Not smiling
* Covering your eyes with sunglasses * Looking away from the camera Remember: This photo is for your professional branding, and your future employers or clients will look at it. It is not for Facebook, Tinder, Grindr, or other social networks that are personal in nature. Do not try to be cute, funny, sexy, or controversial – bePROFESSIONAL.

professional development HIGHLIGHTING CELLS TO QUICKLY VIEW AVERAGE, COUNT, AND SUM IN EXCEL June 21, 2018 Leave a comment I recently needed to check my answers after some data analysis in Alteryx . I computed many averages using a formula in Alteryx, and I wanted to check those results by calculating the average for a few randomly selected rows. I did this by invoking a helpful tool in Microsoft Excel. I will illustrate this functionality with some random data. In Column E, I used a formula to calculate the average of the 3 populations in Columns B, C, and D. To manually check that the formula is correct, I highlighted the 3 columns for ID #125. On the bottom right, Excel calculates the average; it’s difficult to see in the picture below, but Excel confirms that the average is 707,154. Whenever you highlight a range of cells containing numeric data, Excel will provide the average, count, and sum of the selected cells. I did not know about this functionality when I first began working as a statistician, and I am very glad that I did learn it eventually – it is very useful for checking answers by analyzing a few randomly selected rows in Excel!
