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.

The UTD Top 100 Business School Research Rankings
https://jsom.utdallas.edu/the-utd-top-100-business-school-research-rankings/
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. If you spot an error, please send us the corrections at Top 100 Admin.

Beyond Multiple Linear Regression
by Paul Roback and Julie Legler
An applied textbook on generalized linear models and multilevel models for advanced undergraduates, featuring many real, unique data sets. It is intended to be accessible to undergraduate students who have successfully completed a regression course. Even though there is no mathematical prerequisite, we still introduce fairly sophisticated topics such as likelihood theory, zero-inflated Poisson, and parametric bootstrapping in an intuitive and applied manner. We believe strongly in case studies featuring real data and real research questions; thus, most of the data in the textbook arises from collaborative research conducted by the authors and their students, or from student projects. Our goal is that, after working through this material, students will develop an expanded toolkit and a greater appreciation for the wider world of data and statistical modeling. Read more →
