The purpose of the present study was to propose and test a model of role conflict and academic procrastination. This model posits that non-self-determined motivations toward school and interpersonal relationships are positively related to role conflict between these two life domains. In turn, role conflict between school and interpersonal relationships is expected to be positively related to academic procrastination. Participants were 292 university students. Results from structural equation modeling supported the model. It thus appears that self-determination and role conflict are important to foster our understanding of academic procrastination. Theoretical implications of the findings are discussed.
The purpose of this study was to test the causal ordering among perceived autonomy support from health care practitioners, motivation, coping strategies and compliance to dietary self-care activities. Using a cross-lagged panel model, we investigate how these variables relate to one another over a one-year period. A total of 365 adults with Type 2 diabetes participated in the study. Results suggest that autonomous motivation and active planning are reciprocally related over time, and that prior autonomous motivation is related to the extent participants subsequently comply with their diet. Results are discussed in light of Self-determination Theory and the coping perspective.
The aim of this study was to understand the processes explaining the effects of private performance feedback (success vs. failure) on state self-esteem from the stance of sociometer theory and self-determination theory. We investigated whether or not the effect of private performance feedback on state self-esteem was mediated by perceived inclusion as a function of participants' level of task-related identified regulation (i.e., importance of the activity for oneself). Ninety participants were randomly assigned to one of the following three conditions: failure, success, or control. Our regression analyses based on both original and bootstrap samples indicate that perceived inclusion does not mediate the effect of feedback on state self-esteem for individuals high in task-related identified regulation. Such an effect only operates for individuals low in task-related identified regulation. In sum, our results show that the perceived inclusion process proposed by sociometer theory applies more when individuals find that the activity is less important for them (i.e., identified regulation).
As fully prefabricated wood walls (FPWW) are envisioned to increase building envelope performance, the junction between panels becomes crucial. Since FPWW restricts access to the inter-panel joints, it is preferable to generate an upstream mechanism to complete the joint automatically on-site. This study aimed to design a self-sealing joint for FPWW that would achieve high energy standards and accelerate on-site construction. Airtightness tests and thermal bridge assessments were conducted in the laboratory to compare the developed self-sealing joints with different sealing materials. These same tests were conducted on-site, in addition to observations of the assembly speed of conventional prefabricated walls and FPWW. Of all the materials tested, butyl tape showed the tightest connections. This material helps the joint developed to automatically seal adjacent walls spaced up to 7 mm apart. FPWW maximize the industrialization of conventional prefabricated walls by realizing the sealing details and the installation of doors, windows and exterior siding offsite. This way, FPWW could reduce the duration of a conventional single-family residential project. FPWW maximize quality control while reducing transportation costs associated with conventional modular solutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
