Although psychologists have developed many theories to understand human psychology, their underlying logic is still problematic and deviates from reality, leading to limited ability to explain and predict human behavior.This book builds a self-organization model of human psychology and elaborates its core concept, psychological goals, as the key to understand human motivation and personality. Based on this psychological model, it puts forward a set of theories including the self-organizing goal theory of motivation, structural goal change as a perspective on emotion, the goal-system theory of personality, and the “Goal-Driven People” hypothesis. Research shows that this new theoretical system enjoys an apparent advantage over scattered small-scale theories in interpreting and predicting human motivation, emotions, personalities, human nature, cognition, suicide, and other psychological phenomena. This book further explores the applications of the psychological goal theory in leadership research and indicates new directions for leadership theory.

The book explores the application of digital image correlation (DIC) as a non-destructive method for measuring displacement and strain on surfaces, specifically in the context of concrete alkali-silica reaction (ASR) studies. Utilizing a MATLAB DIC code, it aims to improve the ASTM C1260 Standard Test Method for assessing the potential reactivity of aggregates. The research incorporates recycled glass as the aggregate in four different mortar mixtures, highlighting innovative approaches to sustainability in construction materials.

The objective of Kai Zhang and his research is to assess the existing process monitoring and fault detection (PM-FD) methods. His aim is to provide suggestions and guidance for choosing appropriate PM-FD methods, because the performance assessment study for PM-FD methods has become an area of interest in both academics and industry. The author first compares basic FD statistics, and then assesses different PM-FD methods to monitor the key performance indicators of static processes, steady-state dynamic processes and general dynamic processes including transient states. He validates the theoretical developments using both benchmark and real industrial processes.

In this work synthesis and properties of novel Pi-conjugated polymers containing diketopyrrolopyrrole (DPP) and benzodifuranone (BZDF) chromophores in the main chain, which are suitable as active materials in optoelectronic applications, are developed and investigated. The polymers were synthesized via metal-mediated or -catalyzed Suzuki, Stille, Sonogashira and Yamamoto cross-coupling polycondensation reactions or by using oxidative and anodic electropolymerization. The resulting polymers were characterized using gel permeation chromatography, NMR-, UV/vis-, and fluorescence spectroscopy, mass spectroscopy, and cyclic voltrammetry. The polymers exhibit low HOMO-LUMO band gaps and reversible oxidation and reduction processes, which suggests a strong donor-acceptor character. Electrochromic properties were found upon oxidation and reduction. Additionally, a series of cross-linked conjugated microporous polymers was synthesized. They exhibit high surface area and micropores in nanometer range. Furthermore, the influence via variation of electron donor and acceptor on the HOMO-LUMO band gaps of the conjugated polymers was studied.
