The role of social preferences in the organization of a gregarious mammal colony
(University of Waterloo, 2022-12-02)Social preferences are often demonstrated to exist in “intelligent”, long-lived species, such as cetaceans and primates, where individuals have the opportunity to form relationships with conspecifics through repeated ... -
The role of sodium and calcium permeable T-type channels in generating pacemaking currents in invertebrates
(University of Waterloo, 2016-09-27)T-type calcium channels (Cav3) play a key role in generating rhythmic action potentials in excitable cells such as the heart pacemaker and sleep-wake cycles in the thalamus. T-type channels are low voltage-activated ... -
The Role of Stereopsis in the Control of Grasp Forces during Prehension
(University of Waterloo, 2020-05-28)Background: Binocular viewing is associated with a superior prehensile performance, which is particularly evident in the latter part of the reach as the hand approaches and makes contact with the target object. However, ... -
The role of submersed macrophytes in river eutrophication and biogeochemical nutrient cycling
(University of Waterloo, 2012-09-28)The goal of this work is to contribute to the understanding eutrophication in large rivers with a detailed study of the Grand River, an impacted river in highly agricultural and urbanized Southern Ontario. It focuses on ... -
Role of Symmetry in Hisactophilin Folding
(University of Waterloo, 2009-02-23)Hisactophilin is a histidine-rich actin binding protein from Dictyostelium discoideum; it is a member of the β-trefoil superfamily and exhibits a characteristic tertiary structure with three-fold symmetry. The effect of ... -
The Role of the Group Environment in Galaxy Evolution
(University of Waterloo, 2010-08-11)The majority of typically sized galaxies in the local Universe reside in a common dark matter halo with other similar galaxies known as a galaxy group. However, this was not always the case. Nine billion years ago, when ... -
The Role of Transverse Faults in Late Gold Mineralization: A Structural Study of the Maskinonge Lake Fault, Michipicoten Greenstone Belt, Ontario
(University of Waterloo, 2023-10-25)The Maskinonge Lake fault is a late NW-striking fault that occurs at a high angle to the structural features of the gold-producing Goudreau Lake Deformation Zone (GLDZ) in the Michipicoten greenstone belt. The fault is ... -
The Role of Values and Beliefs in Small-scale Fishery and Dried Fish Production: An Exploration of Social Well-being in Fishing Communities of Sagar Island (Indian Sundarbans)
(University of Waterloo, 2020-06-04)This research highlights the diverse values and beliefs associated with small-scale fisheries and dried fish productions and their role in strengthening social wellbeing of fishing communities. According to the Food and ... -
Role of visual information during stair locomotion
(University of Waterloo, 2011-03-30)Vision provides relevant information for safe locomotion in a variety of environments. During stair locomotion visual information may be important to detect step boundaries, transitions between ground level and stairs, ... -
The Role of Wetland Pond Permanence in the Assembly of Biological Communities in the Prairie Potholes of Alberta
(University of Waterloo, 2020-05-06)Wetlands in the Prairie Pothole Region (PPR) support numerous biological communities, and the composition of these communities depends on the length of time ponded water is present (i.e., hydroperiod or permanence class). ... -
The Role of Working Memory in Deductive Reasoning: A Dual Task and Individual Differences Approach
(University of Waterloo, 2008-08-28)The ‘belief bias’ effect is one of the most pervasive findings in the study of syllogistic reasoning. Here, participants respond “valid” to more believable than unbelievable conclusions, regardless of the actual validity ... -
The Role Volunteer Tourism Plays in Conservation: A Case Study of the Elephant Nature Park, Chiang Mai, Thailand
(University of Waterloo, 2009-10-23)This study examined the role volunteer tourism played in the conservation of elephants in Chiang Mai, Thailand. A case study was conducted to determine whether volunteer tourism at the Elephant Nature Park (ENP) had an ... -
The Roles of Causal Propagator in Relativistic Quantum Information
(University of Waterloo, 2023-05-29)This thesis focuses on the roles of causal propagator — the expectation value of the field commutator — in relativistic quantum information. Consider two observers Alice and Bob, each carrying a two-level quantum system ... -
The Roles of Conserved Dbf4 Motifs in DNA Replication and Checkpoint Responses in Saccharomyces cerevisiae
(University of Waterloo, 2010-01-18)The Dbf4 protein is involved in the initiation of DNA replication, in complex with Cdc7 kinase, and also plays a role in the intra-S-phase checkpoint response via an interaction with Rad53 in Saccharomyces cerevisiae. The ... -
The Roles of Daily and Trait Self-Compassion in Mitigating Symptoms of Bulimia Nervosa: Findings From a Two-Week Daily Diary Study
(University of Waterloo, 2020-08-12)Background: For individuals with bulimia nervosa (BN), eating pathology is largely affected by daily experiences (Crosby et al., 2009). Yet, little is known about protective factors that can mitigate bulimic symptoms ... -
