I accepted faculty position at University of Utah

Filed under: Econometrics, Research, Teaching — Rohit Aggarwal @ 5:47 pm

I have accepted tenure track Assistant Professor position in David Eccles School of Business, University of Utah. IS program at University of Utah is growing rapidly. All throughout the country enrollments in IS are down but at Utah enrollments are increasing. IS faculty at Utah such as OliviaPaul and Gautam are really strong in data mining. They have also done a lot of work in recommendation systems. My research tool kit comprises applied statistics, particularly econometrics, network analysis and game theory. You can find a sample of my work here. Our research tool kits are complementary and I am excited over the collaboration possibilities.

Faculty is very vibrant and active at Utah. For instance, they are organizing “2008 Winter Conference on Business Intelligence“, which is a forum for exchanging research ideas/perspectives among IS researchers and business executives. In addition to being a platform for interaction, this forum also gives a good opportunity to enjoy skiing and snow-boarding. I look forward to attending the conference for both reasons :-).

Operations Management- OPIM 204 Spring 2008

Filed under: OPIM 204- Spring 2008 — Rohit Aggarwal @ 6:28 am

Office Hours: 10AM - 6PM on any day (exception if I am out of town)

Office: BUSN 407

Description: Operations Management (OM) can be viewed as the central functional component of any business organization, governing the transformation of resources or inputs (materials, machines, labor, and capital) into outputs (products and services). The focus of OM is to produce high quality output at low cost, while interacting with the other functional components of the business organization (marketing, financing, and human resources) to achieve company goals.

With the advent of the Internet, e-commerce, and global-sourcing, it is becoming more and more difficult for a company to maintain a competitive-advantage based on location, access to local resources, and retailing services. Modern businesses must instead base their ability to compete and generate profit on the systematic management of resources, and on their ability to produce quality output more efficiently than competitors. In recent years this pursuit has developed into a science, and a host of quantitative tools and sophisticated software packages are available to the savvy operations manager.

Objectives:

  • To understand the fundamental OM concepts and quantitative tools required for the efficient production of goods and services
  • To understand the usage of OM software for business decision-making, including the accurate interpretation of quantitative business models and software output

Required text: J. Heizer and B. Render. Operations Management. Prentice-Hall, eighth edition.

Computer requirements: A laptop is required for every class meeting. You will need to install the Excel OM Software.

Grading:

There will be two exams and a non-cumulative final exam.

Homework problems will be assigned and discussed in class but will not be graded. It is however, strongly recommended that each student complete each homework in preparation for the quizzes, which will be graded. These quizzes will be based directly on recent homework assignments and will usually be announced in advance.

Here is the breakdown of how grades will be evaluated:

  • First examination: 25%
  • Second examination: 25%
  • Final examination: 25%
  • Quizzes: 25%

IS academic job market for 2008

Filed under: Research, Teaching — Rohit Aggarwal @ 2:10 am

This year job market for tenure track faculty position in Information Systems is good. The job market has not been good since the dot com bubble burst. Looking at the discouraging market over all these years,  job candidates applied to even those schools where they most likely would not go. For example, I know candidates who have publications in MISQ and ISR but still they applied to pure teaching schools with no AACSB accredition. Looking at the job market it is easy to see that such candidates would end up in good research schools.

But the interesting part is many recruiting schools do not realize this and they believe that they can pick the top candidates of the market. So I compiled the following list of research schools in the market for a reality check.

CMU 3
Wharton 1
NYU 1
Minnesota 1
UC Irvine 1
Univesity of Rochester 1
Maryland 1
Indiana University 1
University of Arkansas 1
UT Dallas 1
UBC 1
Clemson Univ 1
University of Connecticut 1
Boston College 1
Hong Kong University of Science & Tech 1
National University of Singapore 1
University of Calgary 2
University of Wisconsin Milwaukee 2
Iowa State University 1
Temple University 1
University of Utah 1
Case Western Reserve 1
Virginia Tech 1
Boston University 1
Total 28

Note:- Universities are not in any order and this is not an exhaustive list.

MIT OPEN COURSEWARE- Free Online Courses

Filed under: Econometrics, Teaching — Rohit Aggarwal @ 9:53 pm

Today I accidently came across this site and got very impressed. It is good to know that some of my peer academicians are trying to serve society without any expectation of gain. Teaching is a noble cause but teaching to underprivileged is even better. Right now I am super busy, hence I can participate only by monetary contribution. I made a small donation and wish I could have written a bigger cheque, but I am a poor PhD student who is looking for a job. Once I am little settled as a Professor, I would certainly contribute to the site by both teaching and writing bigger cheques.

Since every dollar counts so please open your wallets and DONATE to this noble cause.

P.S. Concern about the quality of courses: I checked for Econometrics and the text book for the course is Introductory Econometrics by Prof. Wooldridge. This is one of the best textbooks at the undergrad level. Recitations on the course site is like icing on the cake. Based on the material discussed I feel the quality of the course is no less than Econometrics 1 that I took in UConn.

Update: “OCW is a free publication of course materials used at MIT.” I missed this part that’s why it is called MIT OCW. I guess, quality of this material has to be good.

COURSE DESCRIPTION: This course is designed to give students basic knowledge and understanding of information technology and its use in the networked economy. It is based on the premise that knowledge of information system is essential for creating a competitive firm, managing global corporations, and providing useful products and services to customers.

COURSE ORGANIZATION: BADM 260 is an online (asynchronous) course. This means that there will be no traditional lectures conducted every week, instead all of the material will be provided to you online using Vista site.  There are obvious advantages and disadvantages of the online course approach:

Advantages:

·        students have more flexibility in managing their course-work and time

·        students do not have to attend lectures

Disadvantages:

·        students are required to be self-motivated

·        students have to be capable of self-studying and self-learning

·        students need to have a systematic approach and good organization skills

WAYS OF COMUNICATIONS: For any communication please email me at the following address- rohit.aggarwal@business.uconn.edu. I will reply to your mails as soon as possible.

REQUIRED TEXTBOOKS: 

·        Textbook 1 - Patrick McKeown, “Information Technology & The Network Economy”, Thomson Course Technology, 2003, Second Edition

·        Textbook 2 - Gary B. Shelly, Thomas J. Cashman, Misty E. Vermaat, “Microsoft Office 2003. Introductory Concepts and Techniques”, Thomson Course Technology, 2006, Second Edition

Co-op has bundled the books together. Optionally, students may purchase the books separately from your preferred textbook vendor.

GRADING:  The final course grade will be based on two written exams, a software (MS Office) practical exam, and online quizzes.

IN-CLASS EXAMS:  There will be one in-class, closed-book mid-term exam and one in-class, closed-book final exam. The exams are non-cumulative and are weighted as stated below.  For each exam, students will be responsible for reading all of the assigned textbook chapters and any additional material discussed and/or posted on the Vista website (see attached schedule).  Make-up exams will only be given for University approved absences.  Students must bring their UCONN photo identification to class exams.

SOFTWARE PRACTICAL EXAM:  In addition to the two written exams, students must complete a hands-on lab practical that will test their proficiency with the Microsoft Office software.  This test will comprise 20% of the course grade.  The software practical exam will consist of an in-class project. The exam will take approximately one hour and will include material from the MS Office projects covered during the semester.   

SOFTWARE PROJECTS: A new software project will be posted on Monday and Thursday every week and its solution will be posted two days after that. These projects will not be considered for final grades of students; however, students must do these projects regularly as the final Software Practical Exam will be based on these projects.

ONLINE QUIZZES: To enforce more systematic approach to studying, I will post five online quizzes on Vista. The quizzes will cover only the material covered in the McKeown textbook (textbook 1 listed above) and supplemental material posted on Vista web site. Each student is required to take quizzes. These quizzes will consist of multiple-choice and true-false questions. The dates of quizzes and the last submission dates are given below in the schedule. 

FINAL GRADE WEIGHTING:

Two written exams

30% each  (60% total)

Practical Exam
