While I was in Dallas, the Isenberg School of Management (ISOM) at UMass Amherst, where I teach, unveiled its new website. It is larger and easier to navigate than the previous one. Plus, it contains information about both upcoming events and news. We are in the midst of searching for a new Dean and also recruiting new doctoral students so the redesigned website should be helpful in both dimensions. ISOM is a fantastic place to teach and do research. It is located in the Pioneer Valley of western Massachusetts, which is home to the Five Colleges and several neighboring colleges. Our students are very bright, hard-working, and very professional. Interdisciplinarity is valued, which makes for a very rich intellectual environment.
This coming Friday, we will be hosting Professor Ellis Johnson of Georgia Tech, who will be speaking in our Spring 2009 Speaker Series in Operations Research / Management Science. His topic will be major airline challenges, a topic very close to home, especially given the horrific crash of the Continental commuter plane last Thursday in Buffalo. I was flying that day to Dallas through Philly on USAir commuter planes. The first leg was incredibly bumpy and I engaged the stewardess in conversation since I was seated in the first row of the plane. We talked about the USAir plane that landed in the Hudson and the bravery of the pilots and crew and the travelers. She told me how those who were in the back of that plane sustained more severe injuries. Who was to know that that very same day, February 12, 2009, a crash would cost the lives of 49 on the Continental commuter plane from Newark to Buffalo with one life lost on the ground (in the house that the plane crashed into with the wife and daughter escaping). Our hearts go out to all the families of those who lost their lives in such a horrible tragedy. Matt Wald (who happens to be a classmate of mine from Brown University days) reported on the crash for the New York Times, from Amherst, NY.

Dallas, INFORMS Lecture, and Making it Just-in-Time
The phone call from USAir came at 4AM yesterday morning -- my 9:30AM flight to DC was cancelled and I was rebooked on the 11:30AM flight to Dallas through Philly with a scheduled arrival time in Dallas at 5:09PM. This was cutting it unnervingly close for my talk which was scheduled for 7PM at Southern Methodist University (SMU), which, for those of you who may have noticed, would be 8PM, my body time. My talk at SMU was being hosted by the Dallas / Fort Worth INFORMS Chapter. The President of the Chapter is Dr. Tim Jacobs of American Airlines and the Vice President is Dr. Patricia Neri, who also handled the arrangements for me. With an audience of professionals from the Dallas area in banking, airlines, etc., and faculty and students from SMU and area colleges and universities I very much wanted to give my talk, "Synergies and Vulnerabilities of Supply Chain Networks in a Global Economy." The first leg of the journey went well and then we sat on the tarmac in Philly for a good 45 minutes and I had the feeling that I would not make it on time for my lecture. Luckily, I had a wonderful companion next to me, a female medical doctor, so some of the time could be spent in very enjoyable conversation.
Amazingly, we arrived in Dallas only 5 minutes late. I grabbed a Whopper from Burger King, something I had not eaten since my daughter was very young, and it was good! After a quick change into a professional suit in the ladies room I ran to catch a cab and had a delightful driver with an accent I could not identify who also had no idea as to where the Trigg Center, the venue for my talk, at SMU was located. Experiencing riding in the HOV lane was fun and the taxi moved smoothly past hundreds of cars, each with only a single driver. The infrastructure was quite good in Dallas and no potholes were experienced. We made it to the SMU campus at about 6:45 and after asking 4 students, found one who knew where the Trigg Center was. I got dropped off, and marched to my speaking venue with my talk on a pendrive. Luckily, two graduate students helped me to set up and the talk went on at about 7:10PM only to finish at about 8:40PM. The discussion afterwards was great and there was even a faculty member in the audience who had gone to Brown University, my alma mater, and had majored in Applied Math and had had my thesis advisor, Professor Stella Dafermos.
We made it back to the hotel at almost 11PM Dallas time. The flights this morning on USAir from Dallas to Bradley (Springfield/Hartford) through Charlotte were both early, which was great, although the shock of 30 degree temps versus almost 70 degrees in Dallas, was eye-opening. My seat-mate this time around was a financial advisor who was a fan of OSU basketball, and their coach is now Travis Ford, who left UMass last year.
I'd like to thank my hosts in Dallas for a very pleasant experience! The Radisson hotel there was also terrific and so quiet!

Science and Research Funding
Dr. Stephen Quake, a professor of bioengineering at Stanford University, wrote a guest column on the New York Times "Judson" blog this past week. In his column, "Letting Scientists off the Leash," he describes the specific challenges of securing grants for scientific research from funding agencies. Many of his points, from the time that writing proposals consumes, to the need for innovative approaches to funding the most original and pioneering scientific research, clearly resonated with the readers of the column. His writeup also made an impact on me and pushed me to comment about some of my own experiences, both successes and failures, in securing grants from funding agencies. You can read my comment -- it is number 16 and follows Dr. Quake's guest column in the NYTimes. Continue reading further the comments of hundreds that wrote in.

Optimal Banner Advertising on the Web
In today's, February 9, 2009 New York Times, Richard Perez-Pena writes a very interesting article about how the Times hopes to survive the recession. Towards the end of the article the issue of how to generate revenue via advertising on the web comes up and Kelly Twohig is quoted, "we have a glut of unsold" space on webpages and "It's about understanding, really, the efficacy of ads..."
Interestingly, and, coincidentally, a team of three female researchers: Dr. Lili Hai, Dr. Lan Zhano, and Dr. Anna Nagurney, with backgrounds, respectively, in computer science, applied mathematics and operations research / management science, have completed a report on how to exploit statistical techniques and optimization in order to design optimal web banners for advertising purposes. Our article develops a rigorous methodology as to how data can be gathered and then exploited so that optimal ads are designed on webpages. Needless to say, the timing of this research report is exciting and, who knows, perhaps the New York Times can make use of it!
I/we can't imagine a world without the New York Times!

Upcoming Travel and Hosting Speakers
As the new semester is gearing up, it is exciting to be able to both travel to give talks as well as to host speakers. Next week, I will be flying to Dallas, Texas, to give a talk, "Synergies and Vulnerabilities of Supply Chain Networks in a Global Economy." I will be hosted by the Dallas/Forth Worth Chapter of INFORMS (The Institute for Operations Research and the Management Sciences). My gracious host will be Dr. Patricia Neri, who works for Southwest Airlines. The talk will take place at Southern Methodist University.
The following week, we will begin our Spring 2009 Speaker Series in Operations Research / Management Science at the Isenberg School of Management at UMass Amherst. Our first speaker, on Friday, February 20, 2009, will be Professor Ellis Johnson of Georgia Tech, who will be talking about Operations Research and Air Traffic Problems. We are delighted that Professor Johnson, who is a member of the National Academy of Engineering, will be inaugurating out Spring Series! UMass Amherst has issued a press release for the series. This will be the tenth semester of this Speaker Series which is organized by the UMass Amherst INFORMS Student Chapter. I serve as the chapter's Faculty Advisor and it is so rewarding to see the enthusiasm of the students in this endeavor. The series adds so much to the intellectual life of the school and university and the students can hardly wait for it to start!

Being Thanked in the Top Physics Journal
One of the truly gratifying aspects of being a Professor is having students that have graduated write back and stay in touch. Last semester, one of my former undergrads, who had taken my transportation & logistics class, brought to my attention a paper that had been published in the top journal in physics, known as "Phys. Rev. Letters." What amazed this graduate of our Operations Management program at the Isenberg School of Management was that he understood the material and much of it was familiar. News about this article, entitled, "The Price of Anarchy in Transportation Networks: Efficiency and Optimal Control," [Phys.Rev.Lett. 101,128701(2008)] had gone viral with articles appearing in The Economist, the Boston Globe, and the New York Times.
After reading the article it became clear to me that many references were missing and, in scholarship, it is imperative to do a thorough literature search, which establishes precedence. Towards that end, with my husband, who has a PhD in physics, we wrote a response documenting some of the major relevant milestones in transportation network research that should have been included in the article. The rebuttal was not published but, lo and behold, this week there is an errata by the authors in Phys. Rev. Letters {Phys. Rev.Lett. 102, 049905 (2009)], which thanks us and includes some of our suggested references. We are pleased that the authors now understand that science moves forward by standing on the shoulders of giants.
The original article had also motivated my Letter to the Editor to The Economist.

They are Back!
The Bement School 9th graders returned last night around 9PM from their service trip to the La Suiza orphanage in the Dominican Republic, only 2 hours or so late, after an unplanned delay at immigration at the JFK airport since one girl's passport and papers were being challenged. Given numerous stories from colleagues and friends about their misadventures at immigration at JFK, the parents of the travelers breathed a big sigh of relief, when we were finally notified that the student group of 20 and their teachers and coaches could proceed through!
When the 9th graders arrived back to Old Deerfield they were welcomed by parents and the excitement of all at the reunion was palpable. What the "Bementers" accomplished in less than a week is amazing -- they built bookshelves at the orphanage, painted what has now become a library and study area, and designed and painted a big mural. Most importantly, they played with the orphans (45 boys in all), carried the younger ones around, since they blossom with the attention, and organized games of basketball, soccer, and baseball. They played checkers with the children, shared books and toys with them, including hula hoops, climbed mango trees, and communicated with one another as only children can -- with hugs and laughter. They also accompanied the older ones to their school down the hill. The Bementers also helped the staff with dish washing and volunteered to do so since the orphanage is so short-staffed.
The fact that few of the 9th graders knew much, if any Spanish, did not matter!
As my daughter said, upon her return, "We had no TVs, no radios, no Internet, and no watches - time just stood still and it did not matter. It was so wonderful!" The food was delicious - pineapples, eggs, chicken, and rice -- the chickens ran freely there!" "We would help putting the little ones to bed and they even prayed for us." "Every night we collapsed to sleep in our large dormitory rooms, girls in one room and boys in another." "There was no hot water in the showers and sinks and we had fun brushing out teeth, sometimes outside." "Mom, you must do something about the traffic in the Dominican Republic, though, since there are no double yellow lines on the roads and the bus rides were interesting."
When my daughter entered our home late last night she ran up to the bathroom and said that she needed time to just stare and appreciate the bathroom amenities, and especially the shower stall.
One wonders whether $$$ sent to such an orphanage might result in physical improvements but, at the same time, the human contact and shared experiences among the students of the US and those at La Suiza may inspire dreams, which may be more fundamental and lasting. Clearly, a way in which to improve and sustain both the physical and educational infrastructure at the orphanage along with more face-to-face support and kindness plus enriching experiences would be ideal.
Such a trip that the Bement 9th graders experienced, with some associated possible risks, builds not only character, but also empathy, discipline, and appreciation. We hope that it is just the beginning of helping to construct an environment in which those who need it most can enjoy their childhoods, knowing that others care, and the process of growing up.
