Ten ways to be an advocate for women and underrepresented minorities in academia

I try my best to make my department, college, university, and discipline a welcoming place where everyone feels welcome and is valued. We’ve come a long way, but we also have a long way to go.

Mentoring has long been used to help support and address inequities that women and underrepresented minorities (URMs) face. Many reports such as this one argue that we should go beyond mentoring to advocacy. Mentoring is often private and done behind the scenes, and as a result, mentoring does not always improve inequities. Advocacy is more public and outward facing, with advocates raising the visibility of their advocees/mentees. Advocates can promote their mentees’ visibility, advocate for their next promotion, make connections for with senior leaders, and connect them with career opportunities. I believe women and URMs need both mentors who “get it” and can offer useful advice as well as advocates who can open doors that mentees cannot do on their own.

Male allies often ask me what they can do to make a difference. Here is my list of ways to advocate for women and URMs. My list builds upon the ideas from Anna Nagurney’s excellent list.

  1. Have at least one female and one URM plenary/keynote speaker if you are organizing a conference.
  2. Invite women and URMs to speak at your campuses in department seminars or as guest lecturers.
  3. Nominate women and URMs for professional society offices and important service roles (e.g., for National Academy of Engineering review committees).
  4. Nominate and appoint women and URMs to journal editorial boards.
  5. Nominate women and URM to serve on awards committees.
  6. Invite women and URMs to apply to positions in your department.
  7. Nominate women and URM colleagues for professional recognition: from students to senior colleagues. Many forms of recognition are not successful on the first try due to so many good nominations. Be ready to try again.
  8. Publicize the successes and achievements of women and URMs in newsletters, media, press releases, etc.
  9. When someone achieves, send them a congratulatory note.
  10. Ask conference organizers if there is a code of conduct for meetings to convey the expectation that the conference is to be a welcoming and inclusive space where all attendees feel safe. If not, ask them to create one.

Regarding the last item, Aurelie Thiele and I helped edit the INFORMS Meeting Code of Conduct with INFORMS staff member Shelley Renn. The Board adopted and introduced it in 2018. I’m very proud of this.

An integrated network design and scheduling problem for network recovery and emergency response

I recently published a paper entitled “An Integrated Network Design and Scheduling Problem for Network Recovery and Emergency Response” in Operations Research Perspectives (volume 5, p. 218 – 231) with my PhD student Suzan Afacan Iloglu.

This paper studies a problem in post-disaster response and restoration. Disasters cause damage to important infrastructure systems such as power, water, and road infrastructure. We were particularly motivated by hurricanes, where the debris on roads after the storm make many roads impassable, which can greatly reduce the connectivity of the road network and substantially increase travel times. Often, teams of repair crews clear the roads before utility crews can come in and restore essential services. Given my experience studying emergency medical services, I was particularly interested in how emergency responders can efficiently deliver aid while the debris is being cleared.

In this paper, we seek to coordinate the activities of two types of service providers: (1) emergency responders who provide essential services and (2) repair crews who install arcs over a finite time horizon. We formulate the problem as a location and scheduling model, where emergency responders are located on a network. These facilities can be re-located over a time horizon while network components (arcs) are installed (the scheduling component). The results shed light on how to prioritize the restoration of damaged road infrastructure to assist in providing emergency aid after a disaster. The solutions indicate how to coordinate the recovery of road infrastructure by taking into account emergency service efforts, which is crucial to save more lives and improve resilience.

 


Punk Rock OR’s New Year’s Resolutions for 2019

I did pretty well with the New Year’s resolutions I made last year.

My New Year’s resolutions this year are:

  1. Unsubscribe, don’t just delete academic spam emails
  2. Blog more frequently about my research.
  3. Continue to say no more often to carve out more time for research that is free from email, twitter, and other distractions.
  4. Write and edit my writing every day, even if only for a few minutes (I did really well at this last year and need to keep the momentum).
  5. Cook meals from scratch more often.
  6. Run the Boston marathon! Last year’s resolution was to qualify and I achieved this goal 🙂

Last year, one of my goals was to read more popular science books. I read

A couple of Punk Rock OR posts deal with setting goals and establishing good habits.

I’ve received a lot of positive feedback on my recent blog post about achieving work life balance.


how queueing theory helped me with work-life balance

I find that mathematical models used to solve systems engineering problems are also useful for managing personal issues I face in everyday life. Stochastic processes and queueing theory helped me find and maintain a healthy work-life balance.

I was often wracked with guilt for taking personal time during graduate school and on the tenure track. Three things really helped.

1. Role models who are successful and who have balance made a big impact. I had an advisor in graduate school who talked about how I should take time off every week, and that was a help even though I often did not follow his advice. I am constantly inspired by colleagues I know who are OR rockstars and also have a healthy home life and engaging hobbies.

2. Having children helped me set healthy limits at work at a young age. I had my first child in graduate school, and in retrospect, that was probably the best thing for helping me find balance personally and professionally. My daughter needed me, and I needed to be there for her. I know the statistics indicate that maybe I am an anomaly, but I have had to balance the demands of work and motherhood throughout my professional life. Learning this early helped me later on.

Note: I am not suggesting that if you are really struggling with work-life balance issues you should have a child. I am certain I was predisposed to handle the transition to parenthood 🙂

3. Caretaking is not the same as taking time off from work; it’s a different kind of work. This is where stochastic processes and queueing theory helped.

I am a single server queue who works day after day. Work enters my queue with rate \lambda and I finish tasks with rate \mu . If the arrival rate of new work exceeds my service rate (i.e., if \lambda / \mu > 1 ), the queue explodes and eventually becomes infinitely long. I can assure you that \lambda / \mu > 1 .

One (unhealthy) way to frame this situation is to note that one way to reduce the length of the queue is to work all the time. But this is futile in the long run.

Another way to frame this situation is to note that I have some inefficiencies in how I work. Over time, I have become more efficient and have increased by \mu .

The third–and best–way to frame this is to accept that at some point, I can no longer improve my efficiency. And at that point, it’s still true that \lambda / \mu > 1 . Queueing theory demonstrates that there is no systematic way to “catch up,” so I might as well take a break to run or go to the symphony or make cookies.

Having said that, I still struggle with guilt if I take breaks longer than one hour. I’m a work in progress 🙂

What helps you find balance?

 


Pre-tenure planning for your post-tenure life: my interview for the Decision Analysis Society

Allison Coffey Reilly and Florian Federspiel interviewed me for the INFORMS Decision Analysis Society’s quarterly newsletter as part of an article about how OR faculty transitioned from pre-tenure to post-tenure life. My interview is below.

Pre-tenure planning for your post-tenure life

For this edition of Ask DAS, we had the exciting opportunity to speak with Drs. Laura Albert (University of Wisconsin – Madison), Jason Merrick (Virginia Commonwealth University, Canan Ulu (Georgetown University), and Jun Zhuang (University at Buffalo) about how they thought about their transition from pre- to post-tenure. We are sharing an excerpt of our conversation below. The transcript has been edited for brevity and clarity.

  • Was there anything that surprised you while preparing your tenure dossier or when going through the tenure process?

Laura Albert (LA): I went through the tenure process twice in two years – first at Virginia Commonwealth University and then at University of Wisconsin – Madison, after I moved. This is not the typical way to do it. The process was significantly more difficult the second time around. If you’ve been at an institution for five years, the process should be fairly straightforward. The institution, college, and department should provide clear expectations during that time. They might provide example portfolios – nothing should be too surprising. But, when a faculty member switches universities mid-stream, that can pose unique challenges. He or she may not be aware of or be able to meet specific institutional or departmental milestones at the new universities. These need to be made clear and then discussed and managed by the new university.

  • It is frequently said that tenure is needed to allow for researchers to take-on riskier research. In what ways did your research or your approaches to research become “higher risk?”

LA: Yes, definitely. Post-tenure is a good time to take on new research projects. One of the difficulties with new research is that there is high start-up cost – it might take 6 – 12 months to scope out the work and get things going. It’s a much better time to get more irons in the fire, which can be very intellectually rewarding. The research itself might not be risky, but the time it takes to get the research going could be seen as a risk if done before tenure.

  • Were there research topics that interested you pre-tenure that you knew you shouldn’t have broached until post-tenure? How did you conclude pre-tenure to wait to pursue the topic?

LA: I have a foot in bracketology, including football rankings, basketball rankings, college football playoff forecasting, and that was totally a post-tenure gift to myself. It such a fun thing to do, mainly for outreach. It gets people excited for industrial engineering and shows people what we do in operations research. Related to that, I developed a course on sports analytics. It’s good to develop some things post-tenure that might not be directly related to your research or that you, per se, having funding to support, but that really brings you enjoyment. For me, it has helped me to establish a balance that I like in my life.

  • Do you think it’s necessary to have a plan prepared pre-tenure for the post-tenure life? If so, how did or would you go about that planning?

LA: I guess, in some ways, I went from having a plan to being more flexible, which has been fun. I’m someone that really focused my time during my pre-tenure period. I had a lot of ideas, but I really only focused on one to two. I wanted to open that up post-tenure. I have been able to be more flexible in the ideas that I pursue. It certainly poses some risk – it doesn’t guarantee that you will get the maximum number of publications out next year that you could otherwise.

  • What do you think is the most misunderstood aspect of post-tenure life?

LA: Oh, you think you are going to be less busy. You’re busier than ever. All of those things that you do to get tenure make people take notice. So, they ask you to do more reviews, serve on more committees, and your department will expect you to do more. And there are often a bunch of research ideas that you have been waiting to pursue.

  • Was there anything that I missed?

LA: I had three children pre-tenure. I did get nervous any time someone brought up the conversion of tenure or children, because children are so often framed as having a negative impact on tenure. There are a lot of exceptions to what we think is the rule. It’s certainly possible to have children on the tenure clock and succeed.

 


how long will volleyball games last with side out vs. rally scoring: a Markov chain approach

I introduced a Markov chain to model volleyball scoring schemes in my course on probability models. I am old enough to remember side out scoring, where a team could score a point only if they served the ball. If the team did not score the point, there would be a side out, and the other team would serve the ball in recognition of winning the play. Games were played to 15 points. Under rally scoring, a team scores a point for every play they win regardless of who served. Games are generally played to 25 points. USA volleyball switched from side out scoring to rally scoring in 1999, and college and high school volleyball switched soon thereafter. More here.

Years after the switch, I met Phil Pfeifer from Darden. We discovered that we both played a lot of volleyball in graduate school. There was a push to rally scoring (then called Fin-30) when Phil was in graduate school well before the switch. He wrote a paper* in 1981 that modeled the two scoring schemes as a Markov chain to identify the situations under which rally scoring would leader to shorter or longer games. Because rec sports could be so lop-sided, it was hypothesized by some that rally scoring would lead to longer games. This is counter-intuitive. The Markov chain analysis confirms that this is true in some circumstances. The games tend to be longer under rally scoring when the serving team tends to hold the serve or when the teams are lopsided.

My slides from class are below. In my slides, I also examine the benefit of serving first under side out scoring. Since the serving team is the only team that can score points, the team that serves first is one step closer to winning. That is an enormous advantage if there is a high probability that the team that starts with the ball holds the serve.

vote early, vote often

Legally, you can only vote once. But if you vote early, you can enable more than one vote to be cast.

Voting in election day is an application of queueing theory. When voter turnout is high, as it is expected to be this year, the queues can become long. Sometimes very long. The lines in Ohio in the 2004 election are infamous. As a result, many voters balked* or reneged** before casting their votes. Alexander S. Belenky and Richard C. Larson ask: Did election queues decide the 2000 and 2004 U.S. presidential elections? Their analysis is summarized in their ORMS Today article.

Practically speaking, queue lines can be reduced one of three ways:

  1. Fewer voters enter the queue
  2. There are more voting booths and people processing voters
  3. Ballots are shorter

Voting early or voting absentee shortens the queues on election day by addressing issue #1. So while you can cast only one vote, casting your vote early means that you can keep the queues shorter on election day and possibly enable someone else to vote who otherwise would not be able to. This is meaningful in practice, since many voters cannot wait in line because of family responsibilities or shift work. So far, 2018 seems to be setting records for early voting. I voted absentee because I will be in Pheonix for the INFORMS Annual Meeting on Election Day.

 

* Balking: The voter decides not to enter the waiting line.

** Reneging: The voter enters the line but decides to leave before voting.
