Is resilience effortlessly innate or is it an acquired skill developed through the endless battle between thriving and self-destruction? The first goal of the present research is to identify mechanisms of resilience. The second goal of the research is to identify mechanisms of resilience, solidifying and expanding upon previously identified mechanisms and examining novel mechanisms. The third goal is to clarify the resilience process as a whole by examining the order of mechanisms that individuals use to foster their resilience within the workplace. It is hypothesized that (1) Autonomous motivation will be the primary foundational mechanism of resilience; (2) Emotional intelligence, challenge appraisals, positive humour and risk-taking will be important mechanisms of resilience and mediate the relationship between autonomous motivation and resilience; (3) The order of mediators will be important in the process of developing resilience; (4) Emotional intelligence will precede challenge appraisals, and risk-taking will precede positive humour. This research project is comprised of 5 studies. Studies 1-4 use linear and multiple regressions to conduct multiple mediation models to evaluate and examine mechanisms of resilience. Study 5 uses a deductive content-analysis approach to analyze qualitative data, to help better understand the nuances of resilience that quantitative data cannot illustrate. Resilience research has many discrepancies relating to its process and mechanisms thus, this research project offers important potential fundamental contributions. By identifying and solidifying mechanisms of resilience, training, counseling, and education will be better informed to have greater success in fostering resilience within individuals and across contexts.

Although previous research has identified a relationship between insecure attachment styles and symptoms of depression and anxiety, evidence regarding the mechanisms of action driving this relationship has been lacking. Consequently, the current study examined the mediating role of resilience in the relationship between insecure attachment styles (i.e. anxious-avoidant, anxious-ambivalent, helpless-disorganized and frightened-disorganized) and symptoms of depression and anxiety. The current study included a sample of 182 participants (i.e., 87 men and 95 women) who completed six questionnaires that assessed each participants' relationship with their caregivers during their childhood, present symptoms of depression and anxiety, and their resilience. Correlational analyses indicated significant relationships among the variables being studied. The formation of an insecure attachment during childhood predicted significantly symptoms of depression and anxiety in adulthood in both men and women. More specifically, the relationship between anxious-avoidant and anxious-ambivalent with symptoms of depression was partially mediated by resilience for men. There were no significant mediation for symptoms of anxiety for me. Within the women population, resilience served as a partial mediator in the relationship between anxious-ambivalent attachment and depression as well as in the relationship between frightened-disorganized attachment and anxiety. Such findings suggested that resilience could act as a protective factor against symptoms of depression and anxiety. These results demonstrated the importance for promoting resilience, especially for individuals who formed insecure attachments during childhood. The importance of studying the relationships among these variables is discussed further.

Gels are used in many applications ranging from bioengineering and pharmaceuticals to food technology and soft-robotics because of their tunable physical and mechanical properties. In many of these applications, the materials need to sustain large deformation. The microstructure of gels changes significantly at large strain values, causing a deviation in the stress responses from that at low strain. The desired mechanical responses of gels can be obtained by tuning their microstructure, therefore, the structure-property relationship for gels is required to be understood for their practical applications. This dissertation discusses two types of gels, one consists of chemical crosslinking and hydrophobic associations, and the other gel only consists of physical crosslinking. The microstructure of these two gel systems is investigated and related to their mechanical responses. The gel system with chemical and physical crosslinking mimics properties of biomaterials like resilin. Resilin is a protein-elastomer that enables biological species for power amplified activities by taking benefits of specific responses of hydrophilic and hydrophobic segments. Inspired by the microstructure and mechanical properties of resilin, a stretchable and resilient hydrogel was synthesized through a simple free radical polymerization technique. These gels retract from the stretched state to the original state with high speed over a short time, such behavior has not been frequently reported for synthetic hydrogels. This gel is also capable of performing a power-amplified activity like catapulting an object. In addition to retraction experiments, the mechanical properties of this gel were investigated in tensile and cyclic loading to determine their resilience. The hydrophobic polymer concentration affects the swelling behavior and mechanical responses such as stretchability and resilience. The second gel system considered here is a physically assembled ABA triblock copolymer dissolved in a B-selective solvent. Here, two different triblock copolymers with different concentrations were utilized. The real-time microstructural change was captured using a RheoSAXS setup with a high flux X-ray beam. The real-time microstructure of these gels subjected to temperature, varying oscillatory strain amplitude, and during relaxation after step strain was captured. This dissertation advances the understanding of the structure-property relationship of microstructurally complex gels towards their potential practical applications.
