Perfectionism and exam performance: The mediating effect of task-approach goals [PDF]

open access: yes, 2015
Perfectionistic strivings are positively correlated with students’ achievement goals and exam performance. However, so far no study has employed a prospective design investigating whether achievement goals mediate the positive relationship between ...

How other-oriented perfectionism differs from self-oriented and socially prescribed perfectionism [PDF]

open access: yes, 2014
Over the past 20 years we have gained a comprehensive understanding of self-oriented and socially prescribed perfectionism, but our understanding of other-oriented perfectionism (OOP)—and how it differs from the other two forms of perfectionism—is still ...

Variable Gain Prescribed Performance Control for Dynamic Positioning of Ships with Positioning Error Constraints

open access: yesJournal of Marine Science and Engineering, 2022
In this paper, a variable gain prescribed performance control law is proposed for dynamic positioning (DP) of ships with positioning error constraints, input saturation and unknown external disturbances. The error performance index functions are designed
