analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Can Laboratory Experiments Test the Cultural Difference?

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...

How video publication of laboratory experiments will solve the reproducibility problem: The Journal of Visualized Experiments

One day, my supervising professor came to me in the lab, pointing to an article in a prestigious research journal, and indicating that we must learn the methodology described in the paper in order to implement it in our laboratory. Back then, in 2005, I was a graduate student in a biology lab at Princeton University, New Jersey. I did my best, but replication of the method and results did not w...

Designing of LQIG method for controlling the wastegate of a turbocharged diesel engine to increase engine output power using experimental results of engine test chamber laboratory

In this paper, first, using a test set on a turbocharged diesel engine in the engine test room, a nonlinear model is obtained and it is linearized around several operation points. Then, for the linear models, a linear quadratic integral Gaussian controller (LQIG) with variable parameters as function of engine speed is designed and simulated. In the proposed method, by controlling the wastegate,...
