A meta-analytic review of leadership impact research: Experimental and quasi-experimental studies

quasi-experimental designs

Avolio BJ, Reichard RJ, Hannah ST.
GSID: t_fQG1IH2hAJ
BJ Avolio, RJ Reichard, ST Hannah… - The leadership …, 2009 - Elsevier

… Our focus included both examining experimental and quasi-experimental as well as lab and field studies conducted in public and private organizations. Our goal was to address a simple question: do leadership interventions have the intended impact and if...

Selective Heavy Element Sensing with a Simple Host-Guest Fluorescent Array.

Analytical chemistry

Liu Y, Mettry M, Gill AD, Perez L, Zhong W, Hooley RJ.
PMID: 28946741
Anal Chem. 2017 Oct 17;89(20):11113-11121. doi: 10.1021/acs.analchem.7b03377. Epub 2017 Oct 05.

A simple three component array of host-fluorophore complexes is capable of sensitive and selective discrimination of heavy metal ions, including lanthanide and actinide salts in aqueous solution. Instead of applying optical sensors that only use "single-mode" detection, i.e., coordination...

Optical resonance imaging: An optical analog to MRI with sub-diffraction-limited capabilities.

ACS photonics

Allodi MA, Dahlberg PD, Mazuski RJ, Davis HC, Otto JP, Engel GS.

We propose here optical resonance imaging (ORI), a direct optical analog to magnetic resonance imaging (MRI). The proposed pulse sequence for ORI maps space to time and recovers an image from a heterodyne-detected third-order nonlinear photon echo measurement. As...

Influence of Oral Progesterone Administration on Drug-Induced QT Interval Lengthening: A Randomized, Double-Blind, Placebo-Controlled Crossover Study.

JACC. Clinical electrophysiology

Tisdale JE, Jaynes HA, Overholser BR, Sowinski KM, Flockhart DA, Kovacs RJ.

JACC Clin Electrophysiol. 2016 Dec;2(7):765-774. doi: 10.1016/j.jacep.2016.02.015.

OBJECTIVES: We tested the hypothesis that oral progesterone administration attenuates drug-induced QT interval lengthening.BACKGROUND: Evidence from preclinical and human investigations suggests that higher serum progesterone concentrations may be protective against drug-induced QT interval lengthening.METHODS: In this prospective, double-blind, crossover...

Effects of roniciclib in preclinical models of anaplastic thyroid cancer.

Oncotarget

Lin SF, Lin JD, Hsueh C, Chou TC, Wong RJ.
PMID: 28978090

Many human cancers have altered cyclin-dependent kinase activity. Inhibition of cyclin-dependent kinases may arrest cell cycle progression and represents an important strategy in the treatment of malignancies. We evaluated the therapeutic effects of roniciclib, a cyclin-dependent kinase inhibitor, as...

Room-temperature superconductivity has been a long-held dream and an area of intensive research. Recent experimental findings of superconductivity at 200 K in highly compressed hydrogen (H) sulfides have demonstrated the potential for achieving room-temperature superconductivity in compressed H-rich materials....
