A Translational Zebrafish Model To Study Breast Cancer Inflammation And Metastasis, Janice Tubman
Electronic Theses and Dissertations
Though modern medicine has greatly improved detection and treatment of breast cancer and overall survival rates are around 85%, this disease is still the second most fatal cancer in Canada. Once the cancer becomes metastatic, it is considered incurable and treatment strategies are directed towards maintenance of the disease rather than curing it. Another hurdle to breast cancer treatment is the severity of side effects from chemotherapeutics, for example cardiotoxicity and hepatotoxicity, that are sometimes fatal. Dexamethasone (Dex) is a synthetic glucocorticoid (GC) that has been shown to be effective at reducing the less severe side effects of chemotherapeutics, such …

Social Information Processing Deficits, Intimate Partner Violence, And Coercive Control In Dating Couples, Jillian Glasgow
Electronic Theses and Dissertations
The current study investigated how social information processing (SIP) deficits are related to intimate partner violence (IPV) and coercive control among heterosexual dating couples. I assessed four steps of Crick and Dodge’s (1994) six-step SIP model, namely: attitudes and attributions, goal setting, coping response generation, and coping response selection. I used Dutton and Goodman’s (2006) theorized model of coercive control, which included assessing demands, surveillance, threats, and victims’ responses to demands. I hypothesized that (a) SIP deficits would be interrelated; (b) participants responding in timed conditions would show more SIP deficits, given theory and research (e.g., Eckhardt et al., 2012) …
