This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...

The purpose of this study was to examine relationships among college students’ 2 2 goal orientations (mastery-approach [MAp], mastery-avoidance [MAv], performance-approach [PAp], performance-avoidance [PAv]), situational motivation (intrinsic motivation, identified regulation, external regulation and amotivation) and effort/persistence in physical activity classes. Participants (140 female, 109...

Why and how the regulation of emerging technologies occurs is not clear in literature. In this study, we adapt multiple streams framework – often used for explaining agenda-setting policy adoption to examine phenomenon. We hypothesize technological change affects policy-making identify conditions under which can be (de-)coupled. trace formulation General Data Protection Regulation show that occ...

aim and background: the aim of the present study was to develop a short form of the persian version of the cognitive emotion regulation questionnaire (cerq-p-short) and to examine its reliability and validity. methods and materials: the cerq-p was administrated to 420 (220 male and 200 female) iranian university students in 2009-2010 academic year. following stepwise omission of the items with ...

Many students in primary education learn arithmetic using adaptive learning technologies (ALTs) on tablets every day. Driven by developments the emerging field of analytics, these adjust problems based learners' performance. Yet, until now it is largely unclear how regulate their with ALTs. Hence, we explored learners effort, accuracy and an ALT moment-by-moment curves. The results indicated th...

This paper examines whether the Peter Principle operates in a large hierarchical financial sector firm. We use a method that allows for variation in optimal effort over stages in the hierarchy, which suggests, at least in the organisation we study, that the mean fall in performance actually understates the effect of the Peter Principle.
