The Psychology of the Handmaid: Margaret Atwood’s Novel Parables of the Possessed Canadian Character

The protagonists of Atwood’s novels are most often both Canadian and female, and their stories feature a common struggle for possession of themselves and their bodies, given various colonizing forces. In relation to her other novels, which I will explore in this essay, the handmaid is a symbol for Canada in relation to the U.S, which stands for “yet another” imperial power infringing upon the lives of Canadians. Atwood herself has stated that the States are extreme in philosophy, while Canadians are more middle-of-the-road. This middle-of-the-road-ness of her main characters gets them into trouble and makes them vulnerable to outside forces. Her protagonists are typically female because the female body itself is particularly open to possession—by pregnancy, rape, cancer, and the physicality of sex. Women in Atwood’s novels are also possessed by spiritual forces, including gods of the wilderness; by men who represent different nations and woo the female “territory”; and by women who represent distinct national traditions or, increasingly, the new Multicultural Canada that is displacing the British-French one. Atwood repeatedly depicts her characters as territories of others, refugees, trespassers, foreigners even on their home ground, and internally divided entities that are inhabitable by others and inaccessible even to the self. They harbor repressed memories that are foreign to their own psyches. Thus Atwood’s novels undercut the Canadian nationalist project that she embarked upon with her 1972 book on a unified Canadian literature. Her novels essentially suggest that, ironically, the uniqueness of the Canadian character lies in its propensity to be possessed

Microstructural and mechanical characterisation of post-tentioning strands following elevated temperature exposure

Prestressing strands lose strength and become more susceptible to creep deformation when they are heated during a fire. The consequent loss in prestressing force could under certain conditions result in structural collapse, potentially outwith the heated region of the structure. This paper describes a test programme characterising the changes in microstructure of steel prestressing tendons exposed to elevated temperatures. The residual strength tests, hardness testing, and elevated temperature mechanical test were performed to demonstrate how recovery and recrystallisation of the initially work-hardened steel produce changes in its mechanical properties at elevated temperatures. The research results of this paper are beneficial not only in the fire design of post-tensioned structures using modern prestressing steel, but also in the assessment of the tendons’ residual strength after being affected by fire

Genome-wide meta-analysis identifies five new susceptibility loci for pancreatic cancer.

In 2020, 146,063 deaths due to pancreatic cancer are estimated to occur in Europe and the United States combined. To identify common susceptibility alleles, we performed the largest pancreatic cancer GWAS to date, including 9040 patients and 12,496 controls of European ancestry from the Pancreatic Cancer Cohort Consortium (PanScan) and the Pancreatic Cancer Case-Control Consortium (PanC4). Here, we find significant evidence of a novel association at rs78417682 (7p12/TNS3, P = 4.35 × 10-8). Replication of 10 promising signals in up to 2737 patients and 4752 controls from the PANcreatic Disease ReseArch (PANDoRA) consortium yields new genome-wide significant loci: rs13303010 at 1p36.33 (NOC2L, P = 8.36 × 10-14), rs2941471 at 8q21.11 (HNF4G, P = 6.60 × 10-10), rs4795218 at 17q12 (HNF1B, P = 1.32 × 10-8), and rs1517037 at 18q21.32 (GRP, P = 3.28 × 10-8). rs78417682 is not statistically significantly associated with pancreatic cancer in PANDoRA. Expression quantitative trait locus analysis in three independent pancreatic data sets provides molecular support of NOC2L as a pancreatic cancer susceptibility gene

Solid-state nuclear magnetic resonance spectroscopy of cements

Cement is the ubiquitous material upon which modern civilisation is built, providing long-term strength, impermeability and durability for housing and infrastructure. The fundamental chemical interactions which control the structure and performance of cements have been the subject of intense research for decades, but the complex, crystallographically disordered nature of the key phases which form in hardened cements has raised difficulty in obtaining detailed information about local structure, reaction mechanisms and kinetics. Solid-state nuclear magnetic resonance (SS NMR)spectroscopy can resolve key atomic structural details within these materials and has emerged as a crucial tool in characterising cement structure and properties. This review provides a comprehensive overview of the application of multinuclear SS NMR spectroscopy to understand composition–structure–property relationships in cements. This includes anhydrous and hydrated phases in Portland cement, calcium aluminate cements, calcium sulfoaluminate cements, magnesia-based cements, alkali-activated and geopolymer cements and synthetic model systems. Advanced and multidimensional experiments probe 1 H, 13 C, 17 O, 19 F, 23 Na, 25 Mg, 27 Al, 29 Si, 31 P, 33 S, 35 Cl, 39 K and 43 Ca nuclei, to study atomic structure, phase evolution, nanostructural development, reaction mechanisms and kinetics. Thus, the mechanisms controlling the physical properties of cements can now be resolved and understood at an unprecedented and essential level of detail
