jQuery Calendar date time picker

Filed under: Web Applications (IS 4460) — Rohit Aggarwal @ 3:08 pm

I came across this very cool jQuery based date time picker. There were some bugs initially in this code, but the owner of this blog (Dan) is a very helpful person.  On my request he fixed the issues and sent me the updated code. 

I have tested it on IE, Firefox, Chrome and Opera, and it works on all.  For trying this awesome date-time picker click here

Here is the picture of this picker:

VPN client for University of Utah

Filed under: Teaching — Rohit Aggarwal @ 4:17 am

If you are looking for a VPN client for University of Utah then the link is here and the details on that page are:

The VPN client software is available at no cost for the following operating systems:

Pick the client according to your system and enjoy the online books at Safari. You will need your university ID and password to download the client.  I would have liked to download the clients and give direct links to my students; but that would have violated University policy because even the download is password protected.

 

An alternative solution to access library’s databases are:

https://tproxy01.lib.utah.edu/login

UNID ID and password.

Hi!

You can find the Course Syllabus here. Please try to keep up with the reading and work out examples regularly. If you will not work regularly then it will be hard to catchup with the class later. 

I will make sure that at the end of the class you are comfortable in making web applications such as a simple online review site.

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

Email: rohit.aggarwal@business.uconn.edu

Phone: 860-486-6485 (shared line)

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.
