Preschool STEAM: Yes They Can!
This project addresses the need for STEM (Science, Technology, Engineering, and Math) initiatives at the early childhood level. Research states that early exposure to STEM initiatives and activities positively impacts elementary students’ perceptions and dispositions (Bagiati, Yoon, Evangelou, & Ngambeki, 2010; Bybee, & Fuchs, 2006; DeJarnette, 2012). The goal of this research is to positively impact the implementation of STEAM (Science, Technology, Engineering, Arts and Math) lessons in the Early Childhood classroom through providing professional development for the Early Childhood teachers. It is hypothesized that through professional development, resources, and support, Early Childhood teachers will build efficacy and build positive dispositions towards developing consistent STEAM lessons for their preschool students
To Cut Pay or Lay Off: Exploring a Vexing HR Challenge
Key Findings:
In today’s turbulent business environment the need to reduce payroll costs can arise at any time. Generally, this means resorting to one of two agonizing options: cutting pay or engaging in layoffs. The challenge, of course, is to select the option that meets the firm’s financial needs while minimizing the potential downsides involved. Several studies have examined the negative effects of cutbacks on employees. The results of these studies are of limited value to decision-makers, however, since overwhelmingly they focus either on pay cuts or on layoffs while making no attempt to compare the two. Here we report on a series of three studies that extends previous research in a couple of ways. Initially, by examining pay cuts versus layoffs to test their comparative effects. And then by explicitly considering the ways in which these effects vary depending on the context in which they are executed
Cryptanalysis and improvement of a biometrics-based multi-server authentication with key agreement scheme
In 2010, Yoon et al. proposed a robust biometrics- based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem. In this letter, however, we show that Yoon et al.’s scheme is vulnerable to off-line password guessing attack and propose an improved scheme to prevent the attack

It was hypothesized that through professional development, resources, and support, Early Childhood teachers would build efficacy and build positive dispositions towards developing consistent STEAM lessons for their preschool students. The findings confirmed this phenomena, however, a gap regarding implementation still exists

Comment on ``Dispersion-Independent High-Visibility Quantum Interference ... "
We show in this Comment that the interpretation of experimental data as well
as the theory presented in Atat\"ure et al. [Phys. Rev. Lett. 84, 618 (2000)]
are incorrect and discuss why such a scheme cannot be used to "recover"
