THE PHD DISSERTATION DEFENSE IN CANADA: AN INSTITUTIONAL POLICY PERSPECTIVE

Drawing upon publicly accessible information on the websites of ten Canadian research universities, this paper aims to shed some light on the assumed variation of institutional policies regarding the PhD dissertation defense in Canada. It discusses How are the institutional policies on the doctoral dissertation defense different across Canadian universities?; What do these differences imply about the role, function, and purpose of the oral defense in the PhD examination in Canada?; and How might these differences inform PhD education in Canada?. It concludes with a call for academics and students’ awareness of these variations in policy and practice.

Charybdotoxin binding in the I(Ks) pore demonstrates two MinK subunits in each channel complex.

I(Ks) voltage-gated K(+) channels contain four pore-forming KCNQ1 subunits and MinK accessory subunits in a number that has been controversial. Here, I(Ks) channels assembled naturally by monomer subunits are compared to those with linked subunits that force defined stoichiometries. Two strategies that exploit charybdotoxin (CTX)-sensitive subunit variants are applied. First, CTX on rate, off rate, and equilibrium affinity are found to be the same for channels of monomers and those with a fixed 2:4 MinK:KCNQ1 valence. Second, 3H-CTX and an antibody are used to directly quantify channels and MinK subunits, respectively, showing 1.97 +/- 0.07 MinK per I(Ks) channel. Additional MinK subunits do not enter channels of monomeric subunits or those with fixed 2:4 valence. We conclude that two MinK subunits are necessary, sufficient, and the norm in I(Ks) channels. This stoichiometry is expected for other K(+) channels that contain MinK or MinK-related peptides (MiRPs)

Non-gapless excitation and zero-bias fast oscillations in the LDOS of surface superconducting states

Recently a novel surface pair-density-wave (PDW) superconducting state has been discovered in Refs. [Phys. Rev. Lett. \textbf{122}, 165302 (2019)] and Phys. Rev. B \textbf{101}, 054506 (2020)], which may go through a distinct multiple phase transition (MPT) when the superconductivity fades away from bulk to the boundary (e.g. edges and corners). Based on the Bogoliubov-de Gennes equations for the attractive tight-binding Hubbard modal in a one-dimensional chain, we demonstrate that the surface PDW state has a non-gapless quasiparticle spectrum, which is contrary to the conventional surface superconducting state. Moreover, we find that the MPT is associated with a zero-bias fast oscillating pattern in the LDOS near the surface. Our findings provide a potential experimental clue to identify the surface PDW state.Comment: 4 figure

COSMOPOLITAN IMAGINATION: A METHODOLOGICAL QUEST FOR QIAOPI ARCHIVAL RESEARCH

For migrants, a family letter may define an absence: of home, of family, of love. It is written to an absence. It may also serve as a way of transporting a migrant home, imaginarily. Each time a migrant writes a letter home, they are making a journey to their family: scenarios with family are developed in their imagination, and thus relationships are crafted, and home is constituted. The practice of letter-writing creates a space that is neither at home nor away sojourning, but somewhere in-between, a space for a migrant to be at home in the world.

'Homeawayness' : experiencing moments of home among Chinese labour migrants

Migration is a major feature of contemporary human life, while making home is ubiquitous. Being away from home creates a space for a migrant to rethink home and to make a home beyond something fixed, spatial, and material. This thesis concerns home and home making in the world of movement. It aims to investigate the ways in which labour migrants make home on their journey away from home, a home through which they express and fulfil themselves while making sense of the world. Based on fieldwork in the Chaoshan region in South China, I approach individual migrants from two practices of migration that have affected the region in the last 150 years: the historical international Nanyang (Southeast Asia) migration (1860s to 1970s) and the contemporary internal rural-urban migration (1980s to present). Specifically, my fieldwork includes participant observation through working in a toy factory with migrant workers and living together with them for a year, as well as some months of archival research of remittance family letters (qiaopi) in a local archive. To study these two different strands of Chinese migration is not aimed primarily at comparing or contrasting them; rather it is an attempt to explore the universal human capacity to make home in a variety of ways beyond socio-cultural or historical constraint. I argue that one experiences and makes sense of home in moments of being, while making home, making self (and vice versa) is a continual process. One is constantly in a process of self-negotiation, oscillating between identities that are being imposed and self- recognised, between one’s reality and one’s imagination, between one’s past and one’s future, and between one’s rootedness and one’s cosmopolitan openness. I conclude the thesis by proposing five keywords for studying home-in-movement: homeawayness, moments of being, interiority, cosmopolitan imagination, and walking knowledge
