The dynamics of buoyant water entering a rotating basin are studied using a series of laboratory experiments designed to elucidate the alongshore transport mechanisms in river plumes. Inflowing water, which is discharged perpendicular to the tank wall, is observed to form a growing anticyclonic bulge and a coastal current downstream of the bulge. Detailed simultaneous measurements of the veloci...
In the study we conducted a meta-analysis of 24 results drawn from 18 papers in the Voluntary Contribution Mechanism public goods game held in two culturally distant regions, namely US and East Asia. We compared the last round contribution rate from the two regions for both 0.5-MPCR and 0.75-MPCR levels as well as the trend and each round’s contribution rate specifically for the 0.75-MPCR level...
Experiment is central to scienti¢c methodology. Within science in general, experiments are used for four primary purposes, i.e. as a tool to explore novel phenomena and to provide systematic observations of processes, to determine the values of key parameters, to test hypotheses and theoretical models, and to validate computational models, which themselves can be considered as numerical experim...
The replicability of some scientific findings has recently been called into question. To contribute data about replicability in economics, we replicated 18 studies published in the American Economic Review and the Quarterly Journal of Economics between 2011 and 2014. All of these replications followed predefined analysis plans that were made publicly available beforehand, and they all have a st...
129 National Tax Journal Vol. LX, No. 1 March 2007 Abstract Laboratory experiments have proven increasingly useful in all areas of economics. This paper discusses the methodology of experimental economics, highlights its strengths and weaknesses, discusses many of the applications of experimental methods to public economics, and suggests topics in which future applications may also prove useful.
Introduction At least since the time of Adam Smith (1776), economists have believed that sellers are likely to discuss common price strategies, but that incentives to defect may be strong enough to break down collusive agreements. Collusion is difficult to study in naturally occurring markets, since sellers will try to hide illegal activities from buyers and from antitrust authorities. Even whe...
This paper presents Automatic Control Engineering Laboratory (ACEL) WebLab, an underdeveloped, internet-based remote laboratory for control engineering education at the Faculty of Electronic Engineering in Niš. Up to now, the remote laboratory has integrated two physical systems (velocity servo system and magnetic levitation system) and has enabled some levels of measurement and control. To per...
This paper shows how to run some experiments of physics, using a virtual laboratory. Such a laboratory is a website, equipped with objects to be measured and measuring instruments, simulated by means of Java Applets. Here we discuss in particular the case of a laboratory in which we can perform, on the Web, some experiments on radioactivity. The proposed virtual environment can be a viable alte...
