    • Advising caution in studying seasonal oscillations in crime rates 

      Dong, Kun; Yunbai, Cao; Wilber, Matthew; McCalla, Scott G. (2017-09)
      Most types of crime are known to exhibit seasonal oscillations, yet the annual variations in the amplitude of this seasonality and their causes are still uncertain. Using a large collection of data from the Houston and Los ...
    • Defining Program Effects: A Distribution-Based Perspective 

      Green, Jennifer L.; Stroup, Walter W.; Fellers, Pamela S. (2017-08)
      In an age of accountability, it is critical to define and estimate the effects of teacher education and professional development programs on student learning in ways that allow stakeholders to explore potential reasons for ...
