An Experiment with Time

An Introduction to Natural Experiment Studies

در دو سخن سردبیری شماره‌های قبل به مطالعات مداخله‌ای (Interventional and/or experimental studies) [1] و مطالعات نیمه تجربی (studies Quasi-experiment) [2] پرداختیم. همان جا، به این نکته اشاره کردیم که برای اندازه‌گیری کارآیی یک دارو، واکسن، برنامه بهداشت عمومی و متغیرهای دیگری از این دست، مطالعات مداخله‌ای بهترین گزینه هستند. تقسیم تصادفی و کورسازی از مؤلفه‌های اساسی یک مطالعه مداخله‌ای است [1]....

Finite-time experiment design with multisines

When the number of data used for an identification experiment is small, the data contain transient effects and these effects contribute to the accuracy of the identified model. Consequently, when designing the optimal input signal for an identification experiment in the case of small data set, these transient effects have to be taken into account. In this paper, we present a methodology for opt...

An Experiment with Inline Substitution

This paper describes an experiment undertaken to evaluate the effectiveness of inline substitution as a method of improving the running time of compiled code. Our particular interests are in the interaction between inline substitution and aggressive code optimization. To understand this relationship, we used commercially available FORTRAN optimizing compilers as the basis for our study. This pa...

Bubbling with Excitement: An Experiment*

Anecdotal and indirect empirical evidence suggest that excitement and market bubbles are intertwined, such that excitement not only arises during bubbles but may also help fuel them. We directly test the impact of excitement on bubbles in a bubbleprone experimental asset-pricing market (Capinalp, Porter, and Smith, 2001). Prior to trading, participants are assigned to emotion inductions through...
