Estimation of the mediation effect with a binary mediator
Statistics in Medicine, 2006AbstractA mediator acts as a third variable in the causal pathway between a risk factor and an outcome. In this paper, we consider the estimation of the mediation effect when the mediator is a binary variable. We give a precise definition of the mediation effect and examine asymptotic properties of five different estimators of the mediation effect. Our

Acetate‐Mediated Effects of Ethanol
Alcoholism: Clinical and Experimental Research, 1994Ethanol has been shown to increase markedly portal blood flow, primarily by increasing intestinal blood flow. This effect of ethanol is reproduced by acetate, infused at rates equivalent to those leading to endogenous acetate production following ethanol administration.

Direction of effects in mediation analysis.
Psychological Methods, 2015Data collected in the social sciences are rarely normally distributed. The linear regression methods that are usually employed to test mediation hypotheses consider moments no higher than second order. Recently discussed methods of direction dependence do consider higher moments.

Immunity: Plants as Effective Mediators
Critical Reviews in Food Science and Nutrition, 2014In the domain of nutrition, exploring the diet-health linkages is major area of research. The outcomes of such interventions led to widespread acceptance of functional and nutraceutical foods; however, augmenting immunity is a major concern of dietary regimens.

The Surprising Effectiveness of Hostile Mediators
Management Science, 2017Contrary to the tendency of mediators to defuse negative emotions between adversaries by treating them kindly, we demonstrate the surprising effectiveness of hostile mediators in resolving conflict. Hostile mediators generate greater willingness to reach agreements between adversaries (Experiment 1).

I HAVE read with interest the proposal for a truce between academic-scientific and professional education which Mr. Stimmel makes in the January issue of this journal.' As a member of the so-called educator group who has also studied on the graduate level in an academic field and who has taught in this field as well as in education, I can appreciate Mr.

Mediation is becoming the premier method of resolving disputes within the construction industry. The linchpin to the mediation process is the mediator. An effective mediator may make the difference between mediation success or failure. Yet, considering the importance of an effective mediator, there is a dearth of information as to the attributes of one

Nonplatelet-mediated effects of aspirin
Drugs of Today, 2002Aspirin has nonplatelet-mediated effects that contribute to its efficacy in the primary and secondary prevention of coronary events. These include antiarrhythmic effects, as shown in animal studies, and antiatherosclerotic effects related to increase in nitric oxide synthesis/activity and reduction in inflammatory mediators.

Statistical assessment of mediational effects for logistic mediational models
Statistics in Medicine, 2004AbstractThe concept of mediation has broad applications in medical health studies. Although the statistical assessment of a mediational effect under the normal assumption has been well established in linear structural equation models (SEM), it has not been extended to the general case where normality is not a usual assumption. In this paper, we propose

Cardiac Effects of the Mediators of Sepsis
1992Like other forms of acute circulatory failure, septic shock is characterized by an imbalance between oxygen demand and oxygen supply. As a result, tissue hypoxia occurs, as reflected by the development of anaerobic metabolism and elevated blood lactate levels.
