A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to statistical methods for mediation analysis. In mediation analysis, the significance of the relationship between the independent and dependent variables has been integral in theory testing, being used as ...

In this paper it is argued that Hintikka’s game theoretical semantics for Independence Friendly logic does not formalize the intuitions about independent choices; it rather is a formalization of imperfect information. Furthermore it is shown that the logic has several strange properties (e.g. renaming of bound variables is not allowed). An alternative semantics is proposed which formalizes intu...

Several variants of a first-order simplification rule for nonnormal form tableaux using syntactic constraints are presented. These can be used as a framework for porting methods like unit resolution or hyper tableaux to non-normal form free variable tableaux.

An alternative approach to the semantics of definite descriptions was proposed by Heim in her dissertation [1982]. Heim assigns to pragmatics a larger part of the task of specifying the meaning of definite descriptions than the neo-Russellians do. In Heim’s theory, definite and indefinite NPs are semantically equivalent, and both introduce free variables. The truth conditions proposed by Heim f...

Mediation analysis empirically investigates the process underlying effect of an experimental manipulation on a dependent variable interest. In simplest mediation setting, treatment can affect through mediator (indirect effect) and/or directly (direct effect). However, what appears to be indirect in standard may reflect data-generating without mediation, including possibility reversed causal ord...

OBJECTIVE To provide examples of post-hoc probing of significant moderator and mediator effects in research on children with pediatric conditions. METHODS To demonstrate post-hoc probing of moderational effects, significant two-way interaction effects (dichotomous variable x continuous variable; continuous variable x continuous variable) were probed with regressions that included conditional ...

In this article, we attempt to distinguish between the properties of moderator and mediator variables at a number of levels. First, we seek to make theorists and researchers aware of the importance of not using the terms moderator and mediator interchangeably by carefully elaborating, both conceptually and strategically, the many ways in which moderators and mediators differ. We then go beyond ...

the increase in the number of university graduates, especially at ma level, in the recent years on one hand and the disproportionate growth of employment on the other hand, has made graduates unemployment one of the major challenges of the country. most students prefer to be employed, while employment capacity in society and increase in the number of students do not match closely. entrepreneurs...

In the article is presented the case of trust-based marketing of over-the-counter (OTC) medicines. The relationship between the hypotheses was tested by means of structural equation modelling. The results of the first model show that the predictor variable (consumer satisfaction with safety and information) has a significant effect on the mediator variable (consumer trust). The results of the s...
