two-step verification(2-Step Verification)

Two-factor authentication is a security best practice. It may be easy to steal usernames and passwords on a user's computer as they are typed, but it is extremely difficult to also target that same user's second factor device. This greatly enhances security because simple attacks to gather usernames and passwords are now almost worthless.

德克萨斯大学达拉斯分校(The University of Texas at Dallas, UTD)的纳文·金达尔管理学院创建了一个数据库,用于跟踪24种主要商业期刊上的出版物。该数据库包含1990年以来在这些期刊上发表的论文和作者单位信息,用于提供1990年以来前100名商学院排名。

Research Rankings Overview

The UT Dallas’ Naveen Jindal School of Management has created a database to track publications in 24 leading business journals. The database contains titles and author affiliations of papers published in these journals since 1990. The information in the database is used to provide the top 100 business school rankings since 1990 based on the total contributions of faculty.

Additionally, the database can also be searched by:

  • Any journal or combination of journals between the time period 1990 to date to get a ranking of schools
  • School name to see a list of publications by a school for any combination of journals and time period between 1990 to date
  • Author name to see a list of publications by an author for any combination of journals and time period between 1990 to date
  • Key phrase in article name to see a list of publications containing that phrase for any combination of journals and time period between 1990 to date

The Jindal School of Management maintains and keeps this website current to provide timely data on research productivity in leading research journals across major disciplines in business schools. The school has worked hard to ensure data integrity, but as with any project of this type where the affiliation data is not always clear, some errors may exist.
