AbstractReplications can make theoretical contributions, but are unlikely to do so if their findings are open to multiple interpretations (especially violations of psychometric invariance). Thus, just as studies demonstrating novel effects are often expected to empirically evaluate competing explanations, replications should be held to similar standards. Unfortunately, this is rarely done, thereby undermining the value of replication research.

Eyal, Liberman, and Trope (2008) established that people judged moral transgressions more harshly and virtuous acts more positively when the acts were psychologically distant than close. In a series of conceptual and direct replications, Gong and Medin (2012) came to the opposite conclusion. Attempting to resolve these inconsistencies, we conducted four high-powered replication studies in which we varied temporal distance (Studies 1 and 3), social distance (Study 2) or construal level (Study 4), and registered their impact on moral judgment. We found no systematic effect of temporal distance, the effect of social distance consistent with Eyal et al., and the reversed effect of direct construal level manipulation, consistent with Gong and Medin. Possible explanations for the incompatible results are discussed.

The current state and problems of agricultural advisory organization in Ukraine on the basis of historical analysis of the evolution of the formation and development of agricultural knowledge and information in the world and in modern Ukraine, the involvement of peasants in the active use of innovative solutions in agricultural production, storage and processing of agricultural products was highlighted. The basic principles of the organization of agricultural advisory activity, features of interaction of advisory services with agrarian business, the government, a science and education were formulated. Forms of scientific-consulting and information support of the processes of transfer of innovative technologies in agro-industrial production were given. Ways to improve the organization of agricultural advisory activities in Ukraine using the potential of the National Academy of Agrarian Sciences of Ukraine were proposed. The edition is recommended for specialists of agricultural advisory services, scientists, teachers and students of agricultural education institutions, participants of the system of training and retraining of personnel of the agro-industrial complex of Ukraine.

Andrews & Kasy (2019) propose an approach for adjusting effect sizes in meta-analysis for publication bias. We use the Andrews-Kasy estimator to adjust the result of 15 meta-analyses and compare the adjusted results to 15 large-scale multiple labs replication studies estimating the same effects. The pre-registered replications provide precisely estimated effect sizes, which do not suffer from publication bias. The Andrews-Kasy approach leads to a moderate reduction of the inflated effect sizes in the meta-analyses. However, the approach still overestimates effect sizes by a factor of about two or more and has an estimated false positive rate of between 57% and 100%.
