description: Unrestrained 53BP1 activity at DNA double-strand breaks (DSBs) hampers DNA end resection and upsets DSB repair pathway choice. RNF169 acts as a molecular rheostat to limit 53BP1 deposition at DSBs, but how this fine balance translates to DSB repair control remains undefined. In striking contrast to 53BP1, ChIP analyses of AsiSI-induced DSBs unveiled that RNF169 exhibits robust accumulation at DNA end-proximal regions and preferentially targets resected, RPA-bound DSBs. Accordingly, we found that RNF169 promotes CtIP-dependent DSB resection and favors homology-mediated DSB repair, and further showed that RNF169 dose-dependently stimulates single-strand annealing repair, in part, by alleviating the 53BP1-imposed barrier to DSB end resection. Our results highlight the interplay of RNF169 with 53BP1 in fine-tuning choice of DSB repair pathways.

description: We present two challenges associated with our current work on a visual lexicon that expresses data absences and ambiguities. First, most visualization approaches fail to express the potential ambiguity and incompleteness in the data they represent. This can pose a fundamental sense-making and communication challenge in contexts (like community organizing), where official data sources and local knowledge may have little overlap or even disagree. Second, indicating expectations, ambiguity, or contradiction between community and administrative data is likely to increase visualization complexity. This increased complexity poses challenges for accessibility and engagement. We outline our work to create a visual lexicon and address the interactions between these challenges.

description: In the large Nc limit, gauge theories with different gauge groups and matter content sometimes turn out to be `large Nc equivalent', in the sense of having a set of coincident correlation functions. Large Nc equivalence has mainly been explored in the glueball and meson sectors. However, a recent proposal to dodge the fermion sign problem of QCD with a quark-number chemical potential using large Nc equivalence motivates investigating the applicability of large Nc equivalence to correlation functions involving baryon operators. Here we present evidence that large Nc equivalence extends to the baryon sector, under the same type of symmetry-realization assumptions as in the meson sector, by adapting the classic Witten analysis of large Nc baryons.

description: From a North American perspective, education as a social system emphasizes the moral and ethical importance of supporting all students’ academic growth and success, as well as ensuring that their basic personal and social needs are met. The role of the school principal has changed significantly over the past 30 years, from primarily fulfilling an administrative function to a multifaceted role involving leading the overall improvement of student achievement, engagement, and well-being, along with ensuring the physiological, social, and emotional needs of students are met. This qualitative exploratory case study explored how five elementary school principals in one large urban school district perceived the tension between the instructional leadership and social leadership expectations of their role as they focused on meeting students' academic and non-academic needs. The research question: How do elementary school principals understand and navigate the tension between instructional leadership and social leadership that is inherent in the principal role? The research is targeted at the tensions that exist to maintain these realms of leadership, not as competitors, but as working mechanisms to support student success. Data were gathered utilizing the following methods: one-on-one semi-structured interviews, reflective principal e-journals, field notes, and site-based artifacts such as school documents and school websites. Data were analyzed using thematic and document analysis. The analysis identified six thematic sections. Time, need, supporting personnel, accountability/responsibility, external supports, and navigating complexities were the themes identified within the principals’ leadership. Eighteen findings were identified. These 18 findings draw attention to the tensions that exist for principals as they address aspects of social and instructional leadership and the ways principals work to effectively and efficiently navigate these tensions to support the students, teachers, staff, and the broader community. One conclusion that can be drawn from this study is that principals draw upon adaptative forms of leadership as they navigate the tensions to meet the needs of students in an equitable and encompassing manner. This study highlights the ways in which principals navigate social and instructional leadership to create inclusive and equitable learning environments for all members of the school community.

We show how a set of non-adiabatic holonomic one- and two-qubit gates can be implemented by utilizing optical transitions in a generic three-level $Λ$ configuration. Our scheme opens up for universal holonomic quantum computation on qubits characterized by short coherence times.

Climate change : assessing the adaptive capacity of community forests
Creators: name: Furness, Eleanor
Publisher: name: University of British Columbia
Year: 2012

description: Community Forests Organizations (CFOs) have been developed in British Columbia (BC) to manage forests according to the needs and desires of local communities and First Nations in forest dependent regions, in order to maximise the economic, social and environmental benefits of forestry. The effects of climate change in many of these regions are expected to be significant, and likely to have a detrimental effect on the health of the forests and communities. However, there are practical steps that CFOs can take which may improve their ability to cope with future conditions such as planting different species, practicing different silvicultural techniques and increasing monitoring and observation of the forest . This study is concerned with what CFOs need to have in place to take these steps. 'Adaptive capacity' is a term used to describe an ability to adjust to change. According to the Intergovernmental Panel on Climate Change (Adger et al. 2007), adaptive capacity depends upon access to natural, physical, economic, human and social capital, as well as enabling guiding values. This study aims to measure and describe each of the components of adaptive capacity in the CFOs in order to ascertain which of these factors are present in more adaptive organisations and may reveal something about the process of adaptation. Describing the nature of adaptive capacity in CFOs could inform policy development in climate change adaptation by both assessing what current capabilities exist in the sector and suggesting potential areas for development.

description: We show that the limiting eigenvalue density of the product of n identically distributed random matrices from an isotropic unitary ensemble (IUE) is equal to the eigenvalue density of n-th power of a single matrix from this ensemble, in the limit when the size of the matrix tends to infinity. Using this observation one can derive the limiting density of the product of n independent identically distributed non-hermitian matrices with unitary invariant measures. In this paper we discuss two examples: the product of n Girko-Ginibre matrices and the product of n truncated unitary matrices. We also provide an evidence that the result holds also for isotropic orthogonal ensembles (IOE).

description: Nuclear spin polarization can be pumped into spin-blocked quantum dots by multiple Landau- Zener passages through singlet-triplet anticrossings. By numerical simulations of realistic systems including approximately $10^7$ nuclear spins during $10^5$ sweeps, we uncover a mechanism of dynamical self-quenching which results in a fast saturation of the nuclear polarization under stationary pumping. This is caused by screening of the field of the nuclear spins. In systems with moderate spin-orbit coupling, self-quenching also screens the spin-orbit interaction. The mechanism is generic and remains robust under a moderate noise. Our finding explains low polarization levels achieved experimentally and calls for developing new protocols that break the self-quenching limitations.

description: Species distribution models can be used to predict climate impacts on biodiversity and guide conservation efforts. However, they may not fully represent biological reality when they entirely rely on climate variables alone and neglect biological interactions. My research objective is to test if including forest cover as a quantitative proxy for shrub-canopy interactions improves the predictive ability of species distribution models. My work focuses on American hazelnut (Corylus americana) as a case-study to test this framework. American hazelnut is a good candidate species because it is widely distributed throughout the eastern temperate and northern forests of North America and is likely to interact with the full gradient of 0 to 100% forest cover. The species remains understudied regarding the determinants of its distribution, despite an excellent fossil pollen record. This project used the hazelnut fossil pollen record to model the influence of canopy cover on distribution through time and to test whether hazelnut niche has been stable over time. For distribution models of American hazelnut, I found no difference in model performance when land cover variables are included at a continental extent. However, at a regional extent I found significant increases in model performance when forest cover was included. These findings suggest that land cover can more precisely define where species habitat exists at a local level compared to climate variables alone. Distribution models developed using fossil pollen occurrences and climate simulations indicate that hazelnut has maintained a consistent niche space over the past 11,000 years before present. However, the limitations of fossil pollen data created less certainty in these results. Future work involves testing this framework on additional species to determine if these patterns are consistent across woody taxa, as well as testing if land cover datasets that are more categorically resolved and include human impacts are able to improve distribution models.

description: Observability of half-quantum vortices and skyrmions in p-wave superconductors is an outstanding open question. Under the most common conditions, fractional flux vortices are not thermodynamically stable in bulk samples. Here we show that in chiral p-wave superconductors, there is a regime where, in contrast lattices of integer flux vortices are not thermodynamically stable. Instead skyrmions made of spatially separated half-quantum vortices are the topological defects produced by an applied external field.

description: The recent multiple-solution problem in extracting physics information from a fit to the experimental data in high energy physics is reviewed in a mathematical viewpoint. All these multiple solutions were found via a fit process previously, while in this letter we prove that if the sum of two coherent Breit-Wigner functions is used to fit the measured distribution, there should be two and only two non-trivial solutions, and they are related to each other by analytical formulae. For real experimental measurements in more complicated situations, we also provide a numerical method to derive the other solution from the already obtained one. The excellent consistency between the exact solution obtained this way and the fit process justifies the method. From our results it is clear that the physics interpretation should be very different depending on which solution is selected. So we suggest that all the experimental measurements with potential multiple solutions be re-analyzed to find the other solution because the result is not complete if only one solution is reported.

description: Background: Peer victimization is a common form of childhood adversity, where children who have experienced victimization have an increased susceptibility to various psychiatric disorders including depression. However, environmental influences have varying degrees of effect between individuals, and therefore our study focused on how genetic predisposition in conjunction with environmental factors interacts to confer risk for depression. Gene by environment (G x E) interaction studies with a focus on candidate genes and polygenic risk scores (PRS-depression) have been conducted in the past for depression, but with inconsistent findings. Testing both candidate genes and PRS, and their interaction with environmental factors, may be a promising approach for understanding the complex aetiology of depression. Methods: Longitudinal data from the McMaster Teen Study have been obtained, where students initially assessed from age 10 (Grade 5) were followed to age 26 (n=875). A computer-based self-reported questionnaire was used to obtain participants’ peer victimization experience and depressive symptoms from age 10 to 26, along with their genotype data. Dopamine transporter gene (DAT1/SLC6A3), monoamine oxidase A gene (MAOA), and the serotonin transporter gene (SLC6A4) were selected for candidate gene analysis. Depression-PRS was calculated using the genome-wide metaanalysis of depression by Howard et al. (2019). Results: Peer victimization was significantly associated with depressive symptoms in adolescence (p < 0.05). Candidate gene polymorphisms and depression-PRS were not significantly associated with depressive symptoms (p > 0.05). Furthermore, there were no significant candidate gene by peer victimization and PRS-depression by peer victimization interactions associated with depressive symptoms. Conclusion: Through our study, findings suggest that exposure to peer victimization experience was independently associated with an increased risk of depressive symptoms in adolescence. Both candidate genetic variants and polygenic risk scores did not have a significant main effect on depression risk. Lastly, neither candidate gene risk nor polygenic risk of study participants were significantly associated with depression following peer victimization experiences. Future studies will greatly enhance our knowledge on how genetic risk plays a potential role in explaining individual differences in the development of depression following adverse environmental exposures, including peer victimization.

description: Depression and anxiety are significant contributors to the global health burden. In Canada, the lifetime prevalences of depression and anxiety among adults are around 11% and 9%, respectively. These mental health disorders (MHDs) increase post-operative adverse events (AEs), worsen outcomes, and negatively impact healthcare correlates. In gastrointestinal endoscopy settings, pre-procedural anxiety reduces patient satisfaction and increases pain sensitivity and requirements for sedatives. Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for managing certain pancreaticobiliary conditions. However, it is technically challenging and has the highest rates of AEs and unplanned hospital encounters (UHEs) among endoscopic procedures. There is a knowledge gap regarding the impact of MHDs on ERCP-related outcomes and patient-reported tolerability with conscious sedation. This thesis presents results from two studies seeking to examine the associations between pre-existing MHDs in adult patients undergoing ERCP and: 1) UHEs within 30 days of the procedure, including unplanned emergency department visits and/or admissions for somatic symptoms only without a clear explanatory diagnosis or AE (Study 1), 2) AEs within 30 days of the procedure (Study 1), and 3) patient-reported peri- and post-procedural tolerability (Study 2). Secondary analyses of multi-centre data were conducted using logistic regression while accounting for pertinent covariates. Study 1 found no significant associations between pre-existing MHDs and UHEs or AEs in 6,648 patients undergoing ERCP within 30 days, including visits or admissions for somatic symptoms alone. Conversely, Study 2 demonstrated a significant association between MHDs and poorer patient-reported tolerability of ERCP under conscious sedation. Among 3,714 patients, significantly more participants with MHDs reported increased intra-procedural awareness and discomfort, along with greater post-procedural abdominal pain, nausea, and distension. Using these data, clinicians performing ERCP can provide accurate information regarding MHDs and ERCP-related outcomes. Additionally, increased awareness of the reduced tolerability and worse patient-reported experience measures of ERCP under conscious sedation in patients with depression and/or anxiety can help endoscopists decrease potential patient morbidity and enhance satisfaction. Further study is needed to determine potential associations between more granular MHD-related exposures and post-ERCP outcomes.

description: Carbon Capture and Storage (CCS) stands out as an effective technique for mitigating the CO2 footprint in the atmosphere. Ensuring the containment of sequestrated CO2 within geological storage is crucial, necessitating continuous monitoring. The research presented here leverages data from the Newell County facility, a shallow CO2 injection project actively promoting advancements in measurement, monitoring, and verification technologies related to CCS. The seismic method proves valuable for estimating frequency-dependent phase velocities of seismic waves. The concept of dispersion reveals that seismic waves of varying frequencies travel with distinct velocities, primarily due to non-uniform elastic properties in the subsurface, leading to frequency-dependent attenuation. As a preliminary step in estimating frequency-dependent seismic attenuation, this study aims to estimate the frequency-dependent phase velocities of the seismic waves as they propagate through the earth. The chosen method involves the analysis of uncorrelated vibroseis data, with a specific emphasis on the frequency dependence of seismic velocities. The estimated phase velocities were further utilized in predicting Q using the Kolsky dispersion model. The lateral and VSP azimuth changes in the phase velocity and seismic attenuation reflect the spatial heterogeneity in the near surface.
Social media : a comprehensive knowledge synthesis and case studies of applications in medicine and health(care)
Creators: name: Grajales III, Francisco Jose

description: Social media are dynamic tools that have allowed virtual socialization and dialogue to emerge on the Internet. Although the term is often used synonymously with social networking and web 2.0, social media have penetrated intra-personal and professional communication extensively and their use has become essentially tacit knowledge among teenagers, and increasingly in the general population. To date, the value of social media to health professionals as a tool for clinical activity and in public health has not been extensively studied. Blogs, Facebook, Twitter, Wikipedia, YouTube, Flickr, Mashups and Second Life are no longer obscure words in the vocabularies of highly technical people. These spaces are starting to replace face-to-face interaction in a large majority of populations and institutions. Healthcare has not been isolated from this trend. The evidence base for the use of social media is rising exponentially, with applications in medical education, collaboration, surveillance, clinical trials, public health, and health services research. However, the comprehensive documentation of how, where and why these tools are affecting health(care) is not well documented. This thesis provides a comprehensive review of the impact of social media in medicine and health(care). Chapter 1 provides an overview of the conceptual and theoretical frameworks, along with the assumptions, that guide the use of social media in the health domain. Chapter 2 synthesizes the what, where, when, how and why social media are being adopted, structured according to the different functionalities of social media. These include blogs, microblogs, social networking, professional and thematic networking, wikis, media sharing tools, mashups, collaborative filtering/bookmarking and other social media (e.g., Second Life). Chapter 2 also discusses a series of clinical implications and recommendations for stakeholders wishing to engage these dynamic spaces. Chapter 3 reviews three recent administrative and judicial cases that have emerged from the inappropriate use of social media and Chapter 4 concludes with the main implications of and significance of the findings. Further research is clearly required to solidify the evidence on the use of social media in health care and to explore and document its economic, clinical, governance and tactical impact and utility.

description: Modifications of short RNAs at specific sites can be achieved commercially by solid-phase chemical synthesis method. However, labelling long RNAs is still challenging for the routine methods. Position-selective Labelling of RNA (PLOR) is a hybrid phase transcription method that allows to label RNAs at desired sites with great flexibility and decent efficiency. In principle, PLOR is a promising method for synthesis of long modified RNAs that are unable to be generated by solid-phase chemical synthesis and other methods. However, as a recently developed method, PLOR has been only applied to label a 71nt and a 104nt RNA, and the limited sequence applications of PLOR may hinder its potential usages. To extend PLOR to more RNAs, we tested the PLOR performances for various RNA sequences. Considering that the controlled transcriptional pauses at the initiation stage in PLOR may lead to different preferences on RNA sequences from in vitro transcription method, we here focused on identifying the effects of the 5ʹ-end and initiated lengths of RNA on PLOR. In addition, our work demonstrated that PLOR efficiencies also varied with linker sizes of DNA templates. This work can facilitate PLOR to be the choice of synthesizing long modified RNAs for more users in the near future.

description: In an effort to contain the coronavirus (COVID-19), nurses were required to socially distance from their patients and use personal protective equipment (PPE). The proximity of nurses and their patients meant that COVID-19 restrictions have impacted the nurse-patient interactions and how nurses perform emotional labour. Most of the research conducted on emotional labour in the nursing profession has been performed in acute care settings; however, there are no known studies that explore the emotional labour of nurses in hemodialysis, where nurses and patients have repeated interactions. In addition, how the COVID-19 restrictions impacted these relationships is also unknown. To examine the impacts of COVID-19 restrictions on nurses’ emotional labour in the hemodialysis workplace, the qualitative methodology of interpretive description was used. Hemodialysis nurses who provided direct patient care in Canada were invited to participate in an online interview. Zoom interviews were conducted (n=6) to explore and understand nurses’ experiences of emotional labour with COVID-19 restrictions in hemodialysis. The results of the interviews suggest that relationships in hemodialysis are casual and friendly. Due to the COVID-19 restrictions, continuous face masking and social distancing presented as physical barriers to developing and maintaining a therapeutic relationship. Nurses attempted various techniques to overcome the challenges that physical barriers created by trial-and-error. Practice experience and exposure to physical barriers, such as face masks and social distance, contributed to the development of confidence. Extensive work experience allowed nurses to feel more confident in their practice and ability to deal with challenges, such as the COVID-19 pandemic. Based on the study’s results, policy makers and healthcare system leaders can help ease the challenges faced by hemodialysis nurses. They can provide additional education and training for nurses on techniques and strategies to help overcome the challenges posed by physical barriers mandated during a public health emergency. This will allow nurses to learn from each other’s practice experience to overcome challenges in building therapeutic relationships.

description: This paper deals with surrogate modelling of a computer code output in a hierarchical multi-fidelity context, i.e., when the output can be evaluated at different levels of accuracy and computational cost. Using observations of the output at low- and high-fidelity levels, we propose a method that combines Gaussian process (GP) regression and Bayesian neural network (BNN), in a method called GPBNN. The low-fidelity output is treated as a single-fidelity code using classical GP regression. The high-fidelity output is approximated by a BNN that incorporates, in addition to the high-fidelity observations, well-chosen realisations of the low-fidelity output emulator. The predictive uncertainty of the final surrogate model is then quantified by a complete characterisation of the uncertainties of the different models and their interaction. GPBNN is compared with most of the multi-fidelity regression methods allowing to quantify the prediction uncertainty.

description: This master’s thesis explores the experiences of registered and licensed practical nurses working in long-term care both during, and in the immediate aftermath of the Covid-19 pandemic in Alberta, Canada. Using Van Manen’s Phenomenology as a guiding research methodology, semi structured interviews were conducted with registered and licensed practical nurses working in long-term care to explore the experiences of the participants. There were four common themes identified from the data: (1) fear and uncertainty, (2) workload, (3) burnout, and (4) resilience and adaptability. These themes have been explored in comparison to the literature with the intention to provide recommendations for future pandemics and the retention of a robust, healthy, and experienced workforce. As the healthcare landscape in Alberta approaches another period of change and flux with the introduction of a system wide restructure, these findings may relate to on-going change within the sector and the turbulence that nurses experience following change. In the wake of the pandemic, the experiences of nurses who battled through it can inform policy makers to implement policies that leverage the strengths of the long-term care nursing workforce.

description: Pedestrian walkways potholes pose significant risks to pedestrian safety, causing accidents and disruptions. This thesis explores using Structure-from-Motion (SfM) 3D reconstruction with smartphone GNSS measurements to improve citizen pothole reporting, aiming to enhance local engagement, infrastructure management, and public safety. The methodology uses SfM camera poses recovered from citizen pothole image reports and relative positioning from smartphone GNSS measurements to resolve the scale ambiguity of SfM pothole models. The relationship between images and a reconstructed point cloud from the SfM technique estimates pothole quantity, perimeter, and maximum depth. Key contributions include developing an integrated system for accurate pothole dimension measurement, with a scale error of approximately 12% from reference measurements, and establishing data acquisition guidelines for assessing the reliability of citizen-reported data. This method results in pedestrian walkway pothole perimeters differing by approximately 35 cm and depths by less than 1 cm. A guide for citizens capturing pothole images is proposed.
