Defying Gravity and Success is the Best Revenge - Nurturing STEM Talent in Our Students, Females and Males

The article by Eileen Pollack in The New York Times, Why Are There Still So Few Women in Science? is a must read. Eileen was one of only two females to receive an undergrad degree in physics from Yale in 1978 and writes eloquently about her experiences and those of other females then and more recently in the pursuit of studies in STEM (science, technology, engineering, and math) fields. She asks a fundamental question as to why still in the new millennium there are so few women in science and math. The conclusion reached in her very thoughtful and well-written article, filled with highlights from various studies as well as personal stories, is that it is the culture and the lack of support and mentorship.

She ends her aticle by describing a picnic back at Yale recently at which there were several female grad students (it was a picnic for the physics and astrophysics departments) in which there were a few female grad students including one African American.  Pollack concludes as follows:
 
The young black woman told me she did her undergraduate work at a historically black college, then entered a master’s program designed to help minority students develop the research skills and one-on-one mentoring relationships that would help them make the transition to a Ph.D. program. Her first year at Yale was rough, but her mentors helped her through. “As my mother always taught me,” she said, “success is the best revenge.” 

As so many studies have demonstrated, success in math and the hard sciences, far from being a matter of gender, is almost entirely dependent on culture — a culture that teaches girls math isn’t cool and no one will date them if they excel in physics; a culture in which professors rarely encourage their female students to continue on for advanced degrees; a culture in which success in graduate school is a matter of isolation, competition and ridiculously long hours in the lab; a culture in which female scientists are hired less frequently than men, earn less money and are allotted fewer resources.

The above speaks to resiliency and the role that, we, as educators, have in nurturing talent and confidence in our students, both females and males alike, in technical fields.  I teach in a business school but have 3 degrees in Applied Math, with a PhD in the specialty of operations research.  I love math, computer programming, and the applications that our tools and methodologies can help to formulate and solve from transportation to financial services to healthcare to logistics and supply chains. I have written about gender inequality in business schools as well.

A kind sentence can make a difference in a student's life and can give her (or him) the confidence to believe in her or himself and to pursue  advanced degrees and careers in areas where you may stand out (this may have some negatives, at first, but people will remember you).

My seventh grade math teacher, Mrs. Fuller, back in Yonkers, NY, said to me, "One day you will be a calculus professor." That statement has stayed with me to this day as have those that have said: "Anna, being a professor is the loneliest profession," and "Anna, the higher you rise, the greater of a target you will be." The latter two were by two of my male professors at Brown and there is wisdom in both statements, which I appreciate.

And culture is clearly so important so we need to increase the visibility of female scientists, engineers, and also business professionals and scholars. The Times article noted the rather stereotypical representation of female scientists and females in the TV series Big Bang Theory.

Let me give you a VERY cool and REAL example of a top female scientist, whom I had the pleasure of meeting at the UMass Rising gala event last April that I wrote about -- the astronaut Dr. Cady Coleman. Cady received her undergrad degree from MIT and her PhD from UMass Amherst in polymer science and engineering.

The photo of Cady and me below was taken at the UMass Rising gala. Cady lives in western Massachusetts with her husband and son when not training and flying in outer space. She was one of the Masters of the Ceremony (along with Ken Feinberg).
There was an article yesterday in our local newspaper, the great Daily Hampshire Gazette (DHG), about Dr. Cady Coleman and how she consulted with Sandra Bullock on the movie Gravity, which will be released today and which also stars George Clooney. She was also featured in Mother Jones with the full article here as well as in Wired. 

In the DHG article, Cady states: I think it's an especially good film for girls. They need models of strong, courageous women who may not always know what to do, but can figure it out. I liked it, in that respect.

 So do be positive with your students -- a few words that recognize talent and an achievement can change a direction of a life!

Supernetwork Center Associates Will Present a Lot of Papers at INFORMS Minneapolis

As I have mentioned in an earlier post, the Annual INFORMS Conference serves not only as an outstanding professional and social networking venue at which we also acquire a lot of information on the latest research by presenters from around the globe on operations research, management science, and analytics, but also it is a great place for a reunion!

It is the venue where many of the Supernetwork Center Associates of the Virtual Center for Supernetworks at the Isenberg School of Management gather!  I founded this Center at the Isenberg School of Management  in 2001 and have been its Director ever since.

Hence, we have been very busy not only with the beginning of the academic year, but also with the preparation of the talks that we will be giving at INFORMS Minneapolis, beginning this Sunday.

This will be an especially thrilling INFORMS meeting for us, since the UMass Amherst Student Chapter will be receiving a Magna Cum Laude Award (its seventh in a series of awards from INFORMS for its activities), Supernetwork Center Associate Dr. Amir H. Masoumi, who is now at Manhattan College, will be receiving the Judith B. Liebman Award (the third Supernetwork Center Associate to be recognized this way), and, yes, you may have heard, I will be inducted as an INFORMS Fellow (this recognition means the world to me -- thank you ever so much).

As the Director of the Virtual Center for Supernetworks, I must say that I could not be prouder of the great work that our Center Associates have been doing. 

Just to give you a sample of our presentation at INFORMS Minneapolis:

Center Associate Professor Jose Cruz of the School of Business at UCONN has organized a great session: Sustainable and Responsible Supply Chain Management, at which 3 papers by members of our group will be presented, including a paper by Professor Trisha Anderson of Texas Wesleyan University and a paper by Professor Tina Wakolbinger of Vienna and Professor Fuminori Toyasaki of York University in Toronto with Thomas Nowak (Tina's doctoral student).

Center Associate Professor Patrick Qiang of Penn State Malvern will be presenting his latest work in a best paper Service Science session -- good luck!

Our Supernetwork Center colleague, Professor Dmytro Matsypura from the University of Sydney in Australia, who is now on sabbatical at the University of Pittsburgh, will be speaking on his work with Professors Kalinowski and Savelsbergh (who was also elected an INFORMS Fellow in 2013).

Amir H. Masoumi (mentioned above) will be presenting our latest work on humanitarian logistics and disaster relief done also with Center Associate Professor Min Yu of the University of Portland. Min will be speaking on our competitive food supply chain research, which was recently published in the European Journal of Operational Research.

My doctoral student, Dong "Michelle" Li, will speak on our work on pharmaceutical supply chains and outsourcing, which is in press in the International Transactions in Operational Research.

And I will be speaking on the network economics of cyber crime, which is the result of a grant and multidisciplinary collaboration with colleagues at UMass Amherst and the Isenberg School.

The above is not even an exhaustive list of the presentations that Supernetwork Center Associates will be giving but it gives an idea of  the breadth and depth of our research activities.

For the latest information on our Center activities, please visit our website.

Looking forward to a super INFORMS conference!

Doctoral Students Tuning Up for INFORMS Minneapolis

A very successful activity of our award-winning UMass Amherst INFORMS Student Chapter, which we initiated last year, was the Tune-Up for the Annual INFORMS Conference. You may recall that the conference was in Phoenix last year.

This year, we will be holding another such event, and it will take place this Friday, from 1-3PM at the Isenberg School of Management at UMass Amherst.

The doctoral students will be giving the presentations that they will be delivering next week at the INFORMS Annual Meeting in Minneapolis.

Information is on the flier below, which the students have prepared. Three presenters are doctoral students in Management Science at the Isenberg School and one is from the College of Engineering.
 This tune-up event gives students (and faculty) the opportunity to learn more about one another's research and provides a nice, welcoming venue in which the students can practice their public speaking and presentation skills. Feedback will be provided and questions are welcome.

This year, one of my doctoral students, Dong "Michelle" Li, will be presenting the paper, Pharmaceutical Supply Chain Networks with Outsourcing Under Price and Quality Competition, by
Anna Nagurney, Dong Li, and Ladimer S. Nagurney, which is in press in the International Transactions in Operational Research. Her presentation can be downloaded here.

The other students will be talking about their work on models and algorithms for applications from transportation (airline and shipping) to healthcare.

Hope to see some of you at the Tune-up on Friday at the Isenberg School!

More information on the chapter's activities can be found on its website.

Politics of Sustainability -- India and China

The title of the talk -- Politics of Sustainability -- intrigued me and it was heavily promoted on the UMass Amherst website, so I gathered two of my doctoral students, one from China and the other from India, and off we went to hear former United Nations policy advisor Mukul Sanwal speak on climate change and sustainability. His talk was under the auspices of the political science department at UMass and Five Colleges, Inc.
Mr. Sanwal worked for the United Nations from 1993 to 2007, serving first as a policy advisor to the executive director of United Nations Environment Programme (UNEP) and later to the executive secretary of United Nations Framework Convention on Climate Change (UNFCCC). Given that the IPCC just produced its Fifth Assessment report, and it has been getting a lot of attention in the media, his topic was especially timely.
Sanwal began his talk by stating that what India and China will do will frame the future. He emphasized the shifting of the population from being producers to being consumers and noted that the global middle class will triple by 2030. He noted that the climate crisis is caused by the scarcity of resources, or the distribution of resources, and sees the problem as one to be managed, and not solved -- I thought this rather pessimistic but very much appreciated his emphasis on conservation and the importance of altering the behavior of consumers. We need to have better ways of measuring carbon imprints and environmental impacts on the consumption side.

In terms of economic development, we are seeing major migrations to urban areas, especially in China and India, and urban design for sustainability is critical. The population was 1.6 billion in 1900 and will increase to 9 billion in 2050. The urban population was 30% (of 2.5 billion) in 1950 and will be 70% (of 9 billion) in 2050. Economies are now driven by the services sector and not just industry.

It is expected that the transport sector will generate half of the global emissions by 2050.

We need to educate the population about changes in lifestyle and, where feasible, also have the right legislation.

Changing behavior is not easy and society needs to agree that changes need to be made. And we can make the changes through the food that we eat, the homes that we live in, and the modes of transport that we use as well as the products that we buy.

We need a common vision for human welfare (and that of our planet).

Ken Toong, our award-winning Executive Director (and chef) of Auxiliary Enterprises, was also in the audience, and he made some great comments on what his group is doing in sustainability in terms of reducing food waste in the dining commons and also serving red meat infrequently. He is in the blue shirt in the photo above.

Lots of ideas were generated -- thanks to Mr. Mukul Sanwal for sharing his experiences and wisdon with us today.

Brilliant Lecture by Dr. Robert Shumsky of Tuck School of Business at Dartmouth

Today, we had the distinct honor and pleasure of hearing Dr. Robert Shumsky of the Tuck School of Business at Dartmouth present the lecture, "Frenemies: Price Competition between Codesharing Airlines," as part of the Isenberg School Dean's Lecture Series at UMass Amherst. He presented this airline codeshare work which was done with Sandra Transchel of the KLU:
http://www.the-klu.org/transchel/


In the morning, Dr. Shumsky met with faculty and our doctoral students and, after lunch at the University Club, which is in a building dating to 1728, regaled us with his research. In his talk, he discussed his modeling work of two codesharing airlines that operate parallel flights, flight legs between the same origin and destination that operate roughly at the same time. Because the flights are close substitutes the airlines are competing for many of the same customers. You can probably think of some international flights that you have considered that fit these assumptions. 

He discussed his dynamic game theory model, under which each codeshare partner dynamically adjusts the prices for seats on its own flight as well as seats on its partner's flight. He contrasted a single time period solution with a multiperiod one with the latter having some fascinating results -- I'll keep you in suspense.

I very much appreciated his incredible energy and interactions with the audience and that he also emphasized the importance of theory -- something I emphasize in my doctoral courses at the Isenberg School and even spoke of the existence and uniqueness of solutions of the Nash equilibrium problem(s).

His talk generated many interesting questions because who does not like to get great prices on international flights?! One question from a doctoral student from South Africa was about how a business class ticket he had booked on Iberia which code shares with British Airways could be $1,500 versus $3,000 and to complicate matters further Finnair also codeshares with the latter.

The photos below were taken today -- I do not take credit for the first "tipsy" one.

Dr. Shumsky also told me the story of how he came to study Operations Research (O.R.) for his PhD at MIT -- Jon Caulkins of CMU, who was then at MIT,  deserves credit for this. What is so great about O.R.
is its applications, which really puts math into action and practice!


Network Economics of Cyber Crime

I have been working on network economics with interfaces to various applications for quite a while, with the first edition of my book on the topic being published twenty years ago!
About two years ago, we were approached to submit a proposal to the Advanced Cyber Security Center, which was soliciting proposals for its Prime the Pump Initiative and our project, Cybersecurity Risk Analysis and Investment Optimization, was funded.

Our project team is interdisciplinary, and consists of Professors Wayne Burleson of Electrical and Computer Engineering, Mila Getmansky Sherman of Finance, Senay Solak, and yours truly of the Operations & Information Management Department, of the Isenberg School of Management, and Chris Misra, of the OIT Department -- all of us at UMass Amherst.

The Project Synopsis:

The vision of this project was to develop:

  • rigorous models for cybersecurity risk,
  • models for costs and benefits of various cybersecurity technologies,
  • techniques for integrating  these models into higher level models that account for other risks and risk management expenditures.
I will be presenting an aspect of our research project at INFORMS Minneapolis in the presentation entitled: Network Economics of Cyber Crime with Applications to Financial Service Organizations.

 The presentation can be downloaded here.

The invitation to submit a paper to the invited session came from Dr. Alla Kammerdiner, whom I met at a marvelous conference in Yalta, Ukraine.

The session information is here.

Dr. Kammerdiner I wrote about earlier in this blog -- she had run the Boston Marathon that was the site for the terrorist attack last April 15.

Another presentation on our project, from a broader perspective, can be accessed here.

Financial Networks -- Special Issue of Computational Management Science


I received a lovely message the other day from a Springer editor which said:

Dear Anna,

I just received my copy of the special issue on “Financial Networks” of Computational Management Science. I am impressed by the excellent outcome, and I would like to thank you very much for this outstanding piece of work. I am definitely convinced that this special issue will help the journal in its positive development and in the task to position itself as a journal of superior quality.

Once more my compliments and thankfulness for your collaboration.

With best wishes,

Christian


Christian Rauscher
Springer
Senior Editor, Business/Economics


How very thoughtful and how much appreciated was the above message. And I do concur, I think that the special issue is really great and below I display the cover of the journal double volume.

My editorial on this special issue can be accessed here. The list of papers and abstracts can be found here. What I especially like about this double volume is that it includes papers by both practitioners and academics and it is so nice to see that research on Financial Networks is continuing to fascinate!

As we say in academia, it may take a while, but good research rises to the top!
