description: This report reviews the recent experimental results from the CLAS collaboration (Hall B of Jefferson Lab, or JLab) on Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) and discusses their interpretation in the framework of Generalized Parton Distributions (GPDs). The impact of the experimental data on the applicability of the GPD mechanism to these exclusive reactions is discussed. Initial results obtained from JLab 6 GeV data indicate that DVCS might already be interpretable in this framework while GPD models fail to describe the exclusive meson production (DVMP) data with the GPD parameterizations presently used. An exception is the $ϕ$ meson production for which the GPD mechanism appears to apply. The recent global analyses aiming to extract GPDs from fitting DVCS CLAS and world data are discussed. The GPD experimental program at CLAS12, planned with the upcoming 12 GeV upgrade of JLab, is briefly presented.

description: We study cosmological models that contain sterile neutrinos with eV-range masses as suggested by reactor and short-baseline oscillation data. We confront these models with both precision cosmological data (probing the CMB decoupling epoch) and light-element abundances (probing the BBN epoch). In the minimal LambdaCDM model, such sterile neutrinos are strongly disfavoured by current data because they contribute too much hot dark matter. However, if the cosmological framework is extended to include also additional relativistic degrees of freedom -- beyond the three standard neutrinos and the putative sterile neutrinos, then the hot dark matter constraint on the sterile states is considerably relaxed. A further improvement is achieved by allowing a dark energy equation of state parameter w

description: We model the evolution of the magnetic fields of neutron stars as consisting of a long term power-law decay modulated by short term small amplitude oscillations. Our model predictions on the timing noise $\ddotν$ of neutron stars agree well with the observed statistical properties and correlations of normal radio pulsars. Fitting the model predictions to the observed data, we found that their initial parameter implies their initial surface magnetic dipole magnetic field strength ~ 5E14 G at ~0.4 year old and that the oscillations have amplitude between E-8 to E-5 and period on the order of years. For individual pulsars our model can effectively reduce their timing residuals, thus offering the potential of more sensitive detections of gravitational waves with pulsar timing arrays. Finally our model can also re-produce their observed correlation and oscillations of the second derivative of spin frequency, as well as the "slow glitch" phenomenon.

Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: North American history

description: This thesis, A Notre Dame Man: How Mike DeCicco Made Notre Dame Fencing into an International Powerhouse argues that Mike DeCicco was different from the coaches who came before him, due to his connections within the American and international fencing community, and his relationship with Father Hesburgh. A Notre Dame Man also contends that a Notre Dame team can succeed without a vocal fanbase, united by a Catholic identity. This thesis engages with histories of sport, ethnicity, class, and gender in twentieth-century American history.
Inside out : young children learning within nature
Creators: name: White, Ruby Jane
Publisher: name: University of British Columbia
Year: 2012

description: The purpose of this research was to expand understanding of the potential value of the natural outdoors as a learning environment for young children. Within the frame of The United Nations Rights of the Child and social constructivist learning theory, this qualitative case study explores young children’s perspectives through their self chosen points of interest within the natural outdoors of their early learning setting. The research site was within an urban/rural interface community in Southwestern Coastal British Columbia. Eight child participants between 3-5 years of age assumed the role of participant researchers to create digital photographs of their outdoor interests, which served as the primary data source. These photographs were supported by video recordings of the children’s ordinary moments outdoors and researcher field notes. The data was coded and categorized using the constant comparison method, resulting in 7 categories and 3 subcategories that revealed the children’s primary interests and points of connection outdoors, as being within and between nature, manufactured objects and people. These points of connection were then merged and discussed within the broader theme of Interfaces and Connections. The discussion includes: categories of interest, contrasts and interactions as they relate to the child/nature literature, early learning practice, children’s rights and social constructivist theory. Also noted is the children’s use of multiple perspectives and their self chosen verbal silences. The limitation and strengths of the research are acknowledged and followed by implications for practice and invitations for future research.
Still in the Closet: LGBTQ People and the Lack of Protections in Conflict Zones

Subjects: subject: International Humanitarian Law
subject: LGBTQ
subject: Political Science--International Law and Relations

description: LGBTQ people have been steadily gaining protections over the last several decades but there is still more progress to be made, especially in conflict zones. LGBTQ people are targeted specifically due to their sexual orientation or gender identity in peacetime, however, this targeting becomes more extreme and violent during times of conflict. One of the more egregious examples of violence targeted towards LGBTQ people was during the Syrian civil war by both the government regime forces as well as other groups like ISIS. The central question of this thesis is why do LGBTQ people face human rights violations in conflict zones despite there being legal protections for civilians? Using securitization theory, I will explore the relationship between securitization of protections for LGBTQ people and the securitization of LGBTQ people as threats. I will use the Syrian civil war as the case study for my analysis to demonstrate that the current protections are not sufficient to adequately protect LGBTQ individuals in states that do not recognize their rights.
Make do with: Reflecting on Landscapes and Rural Spaces in Art

Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Landscape
subject: Rural
subject: Painting
subject: Fine Arts

description: This paper analyses and expands upon the thesis exhibition, Make do with. This body of work used painting to examine relationships with rural landscapes and memory. It asks how the complexity of these landscape relationships—with their layers of personal emotion, memory, and associations—can be conveyed in art. As well, it explores how conveying these ideas can give viewers room to consider their own relationship with these types of landscapes. This paper also considers the nature of landscape as a construction of culture values and memories, rather than outside of human influence. In exploring these questions, this document examines contemporary landscape work in Canada and Alberta, as well as how it interacts with historical context to create work that offers a critical analysis of how culture and personal experience interact with ideas of landscape, within a settler context. The following chapters look to contemporary art practices (which deal with the land and memories of landscape outside of Canada) and how these dynamic methods of working influence the methods and materials employed in this thesis work to examine the interlacing of memory and place with greater scope. Finally, it looks more closely at the mediums and techniques of display, which the title exhibition suggests, to encourage viewers to interact with their own perception of landscape and rural spaces. The art in this body of work looks to create a distinct moment of consideration for how one constructs landscapes in art, as well as in memories and connections to people and places. The significance in this body of work lies in giving a sustained moment of contemplation to the importance which our own experiences, emotions, and memories have in shaping the landscapes around us.
Role of NKT cell activation in malondialdehyde-modified low density lipoprotein immunization for atherosclerosis prevention
Creators: name: Kitano, Naoki
Publisher: name: University of British Columbia
Year: 2012

description: Atherosclerosis is a chronic inflammatory disease involving lipid accumulation in the arterial wall and is currently the top cause of death in Western countries. Currently available therapies involving risk factor modifications have been proven effective, but clinical trials show that this approach only leads to a 40% relative risk reduction. Therefore, new therapies targeting the disease process are needed to improve the efficacy of current atherosclerosis treatment. In vivo studies have shown that immunization with disease associated antigens such as malondialdehyde-modified LDL (MDA-LDL) reduces atherosclerosis progression through induction of protective antibodies. Despite these findings, translation into human use have been difficult for numerous reasons with one being difference in the adjuvant used between humans and animals. Therefore, in vivo immunization studies using adjuvants that can also be used safely for humans are needed to better predict human response from animal data. In this thesis, MDA-LDL immunization studies using α-galactosylceramide (α-GalCer) as an adjuvant aimed for atherosclerosis prevention were done. α-GalCer is a glycolipid that has been shown to be safe for human use and it activates immunomodulatory NKT cells which recognize glycolipid antigens presented by CD1d molecules. We demonstrate that co-injection of α-GalCer with MDA-LDL results in enhanced antibody response, plasma cell formation and induction of antigen-specific Th2 response. This effect was NKT cell and CD4+ T cell dependent but independent of hyperlipidemia. Importantly, use of α-GalCer adjuvant resulted in a 40% reduction in lesion size compared to controls and the extent of reduction was comparable to immunizations including adjuvants used in previous animal studies. Our results demonstrate that α-GalCer can be used as a vaccine adjuvant for atherosclerosis prevention and may likely be one adjuvant candidate for clinical studies.

description: The renormalization group (RG) corrected gravitational action in Einstein-Hilbert and other truncations is considered. The running scale of the renormalization group is treated as a scalar field at the level of the action and determined in a scale-setting procedure recently introduced by Koch and Ramirez for the Einstein-Hilbert truncation. The scale-setting procedure is elaborated for other truncations of the gravitational action and applied to several phenomenologically interesting cases. It is shown how the logarithmic dependence of the Newton's coupling on the RG scale leads to exponentially suppressed effective cosmological constant and how the scale-setting in particular RG corrected gravitational theories yields the effective $f(R)$ modified gravity theories with negative powers of the Ricci scalar $R$. The scale-setting at the level of the action at the non-gaussian fixed point in Einstein-Hilbert and more general truncations is shown to lead to universal effective action quadratic in Ricci tensor.

A realisation of Lorentz algebra in Lorentz violating theory

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A Lorentz non-invariant higher derivative effective action in flat spacetime, characterised by a constant vector, can be made invariant under infinitesimal Lorentz transformations by restricting the allowed field configurations. These restricted fields are defined as functions of the background vector in such a way that background dependance of the dynamics of the physical system is no longer manifest. We show here that they also provide a field basis for the realisation of Lorentz algebra and allow the construction of a Poincaré invariant symplectic two form on the covariant phase space of the theory.

description: We introduce the confident voter model, in which each voter can be in one of two opinions and can additionally have two levels of commitment to an opinion --- confident and unsure. Upon interacting with an agent of a different opinion, a confident voter becomes less committed, or unsure, but does not change opinion. However, an unsure agent changes opinion by interacting with an agent of a different opinion. In the mean-field limit, a population of size N is quickly driven to a mixed state and remains close to this state before consensus is eventually achieved in a time of the order of ln N. In two dimensions, the distribution of consensus times is characterized by two distinct times --- one that scales linearly with N and another that appears to scale as N^{3/2}. The longer time arises from configurations that fall into long-lived states that consist of two (or more) single-opinion stripes before consensus is reached. These stripe states arise from an effective surface tension between domains of different opinions.

Interfacial Transitions and Microstructure Evolution of Materials

description: In this thesis, a thermodynamically consistent phase field formulation was developed to identify the physical origin of interfacial transitions that drive macroscopic phenomena, start- ing at the single-particle length scale and building up to the polycrystalline length scale. At the single-particle length scale, the framework identified two interfacial phases that are stable at the surface of Sn nanoparticles: 1) a disordered interfacial phase, i.e., the experimentally observed premelted surface layer; and 2) an ordered surficial phase displaying a remnant de- gree of order in fully melted particles. Regimes of melting behavior as a function of particle size and temperature are discussed. To bridge the gap between single-particle and densified polycrystals, an analytical model was developed to capture the physical driving forces for densification during electric field-assisted sintering. Here, the model acknowledges the struc- tural contributions of particle-particle interfaces to the strength of mechanical, electrical, and surficial driving forces for densification, and shows good agreement with experimental flash sintering data. Finally, the theory was applied to polycrystalline LiCoO2 (LCO) and shows that the experimentally observed metal-insulator transition is driven by grain bound- ary lithium segregation, the interfacial misorientation, and the size of the abutting grains. A critical misorientation as a function of the macroscopic lithium content exists above which the grain boundaries undergo a metal-insulating transition, suggesting that the fabrication of textured LCO microstructures will delay the metal-insulator transition.

description: Objectives: To examine the association between previous history of concussion and measures of the cervical spine, vestibulo-ocular reflex, oculomotor, and dynamic balance in adolescent (aged 10-19 years) sport participants. Participants: 1653 adolescents [988 (59.77%) male; 653 (39.50%) females; 12 (0.73%) undisclosed] participating in SHRed Concussions (Surveillance in High school and community to REDuce the risk of Concussion and their consequences). Assessment of Risk Factors: Generalized estimating equations were used to examine the association of clinical outcomes with previous number of concussions (0, 1, 2+). Model covariates included age (years), sex (male/female), baseline symptom severity score (xx/132), and sport type (collision/non-collision). Outcome Measures: Cervical [Range of motion (ROM), flexor endurance (CFE), flexion-rotation test (CFRT), head perturbation (HPT)], vestibulo-ocular reflex [head thrust (HTT), dynamic visual acuity (DVA)], oculomotor (symptom provocation / performance on smooth pursuit, horizontal and vertical saccades, and convergence) and dynamic balance [combined functional gait assessment (C-FGA)]. Results: An association was found between concussions history and clinical outcomes of vertical saccades symptom [OR1 relative to 0: 2.02, (1.09-3.76)] convergence performance [OR1 relative to 0: 2.02 (1.09-3.76)] and errors on CFA [OR2+ relative to 0 -0.14, (-0.58-0.30)]. In addition, the association between concussion history was modified by sex for the CFRT [OR males 1 relative to 0: 0.52 (0.27-0.99)], horizontal saccades symptom [OR females 2+ relative to 0: 4.08 (1.56-10.65)], vertical saccade performance [OR females 2+ relative to 0: 2.25 (1.30-3.92)], and HTT [OR females 1 relative to 0: 2.25 (1.30-3.92)]; OR females 2+ relative to 0: 2.25 (1.30-3.92); OR females 2+ relative to 0: 2.25 (1.30-3.92)]. Conclusion: Differences based on concussion history existed in all clinical domains, with females with a history of concussion(s) typically having poorer outcomes. Future research is needed to better understand the relationship between concussion history and clinical outcomes.

description: Indigenous culture and community is interconnected to Indigenous relationality and essential to understanding an Indigenous worldview. Nevertheless, a history of colonialism marked by enduring acts of cultural dislocation, such as the trauma of residential schools, the Sixties Scoop, the Millennium Scoop, and various acts of legislation and relocation, has led to many Indigenous individuals being raised without connection to their Indigenous cultures or communities. This thesis utilizes an Indigenous Storywork methodology in conjunction with Research as Ceremony, Desire-based research, and a conversational approach to address a central question: How do Indigenous individuals raised without integrated connection to their cultures and communities experience reconnecting with their Indigenous cultures and communities? In relational collaboration with three storytellers who were separated from their Indigenous cultures and communities during their upbringing, this thesis places their stories of reconnection into relationship with each other and three additional publicly shared stories of Indigenous reconnection journeys. This relational approach yields profound insights into the unique experience of reconnection with four overarching themes: Displacement, Confusion, Longing, and Reconnection. These themes intricately detail the multifaceted experiences, obstacles, and strengths encountered on Indigenous reconnection journeys, providing the opportunity to listen, learn, and understand. This research carries potential implications for future research and practice concerning journey-informed work with Indigenous Peoples who have experienced separation from their cultures and communities, deepening understanding of the intricate relationalities and dynamics they may be navigating along their journeys of reconnection.

description: The observed stellar mass function (SMF) is very different to the halo mass function predicted by Lambda-CDM, and it is widely accepted that this is due to energy feedback from supernovae and black holes. However, the strength and form of this feedback is not understood. In this paper, we use the phenomenological model GALFORM to explore how galaxy formation depends on the strength and halo mass dependence of feedback. We focus on 'expulsion' models in which the wind mass loading, beta, is proportional to 1/\vdisk^n, with n=0,1,2 and contrast these models with the successful Bower et al.\ 2008 model (B8W7). A crucial development is that our code explicitly accounts for the recapture of expelled gas as the system's halo mass (and thus gravitational potential) increases. We find that a model with modest wind speed but high mass loading matches the flat portion of the SMF. When combined with AGN feedback, the model provides a good description of the observed SMF above 10^9 h^-1 Msol. However, in the expulsion models, the brightest galaxies are assembled more recently than in B8W7, and the specific star formation rates of galaxies decrease strongly with decreasing stellar mass. The expulsion models also tend to have a cosmic star formation density that is dominated by lower mass galaxies at z=1-3, and dominated high mass galaxies at low redshift. These trends are in conflict with observational data, but the comparison highlights some deficiencies of the B8W7 model also. The experiments in this paper give us important physical insight to the impact of the feedback process on the formation histories of galaxies, but the strong mass dependence of feedback adopted in B8W7 still appears to provide the most promising description of the observed universe.

description: We investigate nonrelativistic quantum mechanics on the discretized half-line, constructing a one-parameter family of Hamiltonians that are analogous to the Robin family of boundary conditions in continuum half-line quantum mechanics. For classically singular Hamiltonians, the construction provides a singularity avoidance mechanism that has qualitative similarities with singularity avoidance encountered in loop quantum gravity. Applications include the free particle, the attractive Coulomb potential, the scale invariant potential and a black hole described in terms of the Einstein-Rosen wormhole throat. The spectrum is analyzed by analytic and numerical techniques. In the continuum limit, the full Robin family of boundary conditions can be recovered via a suitable fine-tuning but the Dirichlet-type boundary condition emerges as generic.

description: This study pertains to the creative explorations of the human voice and the radio medium through a portfolio of four projects titled Voice Station. The research and creative processes of the portfolio draw on the practices of radio art, a genre that encompasses a wide range of artistic experimentations with the conventions and complexities of the medium. Voice Station centres the human voice as the only compositional material to investigate how recorded and mediated voices can be used artistically in diverse radio environments by employing distinct platforms and technologies: Voice Station I (2019-21) is a fixed-medium composition that offers a sonic vocabulary for the portfolio and, thus, establishes its conceptual and technological foundations; Voice Station II (2021-22) is a web-based, participatory live stream comprising vocal materials contributed and curated by the participants; Voice Station III (2022) is a radio installation that invites visitors to an interactive listening experience via the radio dial in a gallery environment; finally, selected episodes of my ongoing radio program at CJSW FM, Vocal Cords, provide an examination of the relationships between radio and voice from a broader perspective of campus and community broadcasting. The vocal catalogue, audio processing methods, and formal strategies emerging from each project are recycled and evaluated throughout the portfolio. This iterative practice uncovers sonic and metaphorical similarities between the two core concepts of this study, radio and voice, and presents a structural model shared by each project.
The Association between Adolescent Dating Violence, Depressive Symptomology, and Subjective Well-Being: School Climate as a Protective Factor

description: Adolescent dating violence (ADV) is a worldwide concern that is associated with negative mental health outcomes. Research in ADV is saturated with identifying risk factors to reduce the prevalence of ADV, however, research on protective factors associated with ADV is scarce. This project attempts to fill this gap by examining school climate as a potential protective factor. Health Behaviour in School-Aged Children (HBSC) data were used to examine the association between ADV, depressive symptomology and subjective well-being in a nationally representative sample of Canadian youth, and whether this relationship was moderated by school climate and/or teacher support. Linear and logistic regression analysis was conducted, and results demonstrated that individuals who experienced ADV (either victimization only or mutual violence) had lower subjective well-being scores and greater odds of experiencing depressive symptoms. More positive school climate and teacher support scores were also associated with higher subjective well-being and lower depressive symptoms. Youth who experienced ADV also had lower school climate and teacher support scores, a statistically significant difference as compared to youth who did not experience ADV. However, a statistically significant interaction was not found between school climate or teacher support and ADV on depressive symptomology or subjective well-being. This study emphasizes the importance of continuing to explore ADV among Canadian youth, as well as the role that school climate plays in adolescent mental health. Future research should also explore mechanisms that explain the ADV-depressive symptoms/subjective well-being associations, to identify protective factors and advance a strength-based approach to ADV research.

description: Canada's role in supporting the global refugee crisis has been significant. However, the COVID-19 pandemic has introduced new challenges, impacting the resettlement of refugee groups globally. Nationalist tendencies, already prevalent in populations, have been exacerbated, leading to increased biases against other groups and the reinforcement of borders in host nations. Negative representations of refugees can influence immigration policies, further restricting their admittance into host countries. To better understand public sentiment towards refugees, this mixed methods study looks at Canadian Twitter users’ online messages related to refugees. Employing an innovative computational quantitative methodology of sentiment analysis, the study evaluates shifts in public sentiment towards refugees. The results of the sentiment analysis reveal a significant shift in sentiment during the pandemic. Qualitative content analysis, along with critical discourse analysis, shed further light on themes that emerged from the tweets. These include pandemic-related discussions, increases in xenophobia, racism, and prejudice, and a decline in community support. By integrating the results of both quantitative and qualitative analyses, the study provides a comprehensive understanding of the shift in sentiment toward refugees during the pandemic. This research has implications for immigration policy, particularly concerning the resettlement of refugee groups, and contributes to the broader understanding of how public sentiment shapes responses to the global refugee crisis. Furthermore, the study highlights the potential of innovative methodologies like sentiment analysis to gauge public opinion on widely-used social media platforms.

description: We construct a sheaf of N=2 vertex algebras naturally associated to any Poisson manifold. The relation of this sheaf to the chiral de Rham complex is discussed. We reprove the result about the existence of two commuting N = 2 superconformal structures on the space of sections of the chiral de Rham complex of a Calabi-Yau manifold, but now calculated in a manifest N=2 formalism. We discuss how the semi-classical limit of this sheaf of N=2 vertex algebras is related to the classical supersymmetric non-linear sigma model.

Homeostasis: A Novel and Examination of AI Sentient City Living

description: Homeostasis: A Novel and Examination of AI Sentient City Living is the first novel of a trilogy that considers life in a city dominated by AI technology. With the ubiquity of AI-powered technologies, human and machine now live in tandem, developing alongside one another. This new closeness to machine subverts human identity and asks where the body ends. Language, voice, and names function to finalize human identity, but with advanced AI developments, machines gain the same language, develop their own voices, and are even given names. Through this intervention, my creative thesis digitalizes identity and overlays onto the real world an augmented reality where information is constantly communicated and constantly revised. With the abundance of smart technology that constantly communicates with and responds to humans, the sentient AI becomes less science fiction. What does it mean to know language—to have a voice—to have a name? What does it mean to be sentient? I interrogate the sentient AI further, however, to revitalize space and place. By examining and synthesizing Tim Cresswell’s “place,” Gaston Bachelard’s “home,” and putting these into conversation with “sentient home” narratives, I believe that place, through the abundance and embeddedness of technology, similarly develops sentience. Place—that personalized space—now has the potential to purport its own agenda. By investigating both older and newer narratives like E. M. Forster’s “The Machine Stops” and Netflix’s Love Death and Robots episode, “Lucky 13,” my thesis examines the timeless question of what a place means for the individual. I conclude that the human/machine/place relationship is a three-way mutualistic symbiosis, and no longer is the human passively being protected by place or passively being served by machine. With machines and places gaining a sense of sentience—a sense of their own will—the human, as an organism within the augmented space, also sustains the machine, and place.

description: In recent decades, artificial intelligence has undergone significant development, partly driven by an exponential increase in computational power. In this context, various techniques have been developed that allow the machine itself to learn to predict based on certain data. The purpose of this study is to use these machine learning techniques for the analysis and study of the stock market indicator IBEX35. To achieve this, data from different vari- ables that may have a direct relationship with the value of this indicator will be collected, such as the Dow Jones index or the price of gold. Once the different data is collected, various artificial intelligence models will be trained, and subsequently, the results obtained by these different models for predicting the index value will be analyzed.

description: Initial data for numerical evolutions of binary-black holes have been dominated by "conformally flat" (CF) data (i.e., initial data where the conformal background metric is chosen to be flat) because they are easy to construct. However, CF initial data cannot simulate nearly extremal spins, while more complicated "conformally curved" initial data (i.e., initial data in which the background metric is \emph{not} explicitly chosen to be flat), such as initial data where the spatial metric is chosen to be proportional to a weighted superposition of two Kerr-Schild (SKS) black holes can. Here we establish the consistency between the astrophysical results of these two initial data schemes for nonspinning binary systems. We evolve the inspiral, merger, and ringdown of two equal-mass, nonspinning black holes using SKS initial data and compare with an analogous simulation using CF initial data. We find that the resultant gravitational-waveform phases agree to within $δϕ\lesssim 10^{-2}$ radians and the amplitudes agree to within $δA/A \lesssim 5 \times 10^{-3}$, which are within the numerical errors of the simulations. Furthermore, we find that the final mass and spin of the remnant black hole agree to one part in $10^{5}

description: The session began with a brief overview of strategies from the recently published chapter “Instructional Strategies for Synchronous Components of Online Courses,” from the book Creating Teacher Immediacy in Online Learning Environments by IGI Global (www.igi-global.com), as part of the Advances in Educational Technologies & Instructional Design (AETID) Book Series.  This included a handout of strategies, so that participants had a baseline of concrete ideas to take home.

    This chapter provides a toolkit of strategies for online faculty, course designers, and administrators interested in implementing a synchronous component of an online course.  Synchronous course components provide rich opportunities to engage students, bring distinct instructor personalities and strengths to life, and personalize courses to specific school cultures.  Strategies discussed appeal to a range of budgets, so as to be applicable and sustainable at any school.  The chapter also includes recommendations for resolving the myriad challenges faced when implementing synchronous components of online courses.

    The ideas from the chapter come from Columbia University’s School of Professional Studies and School of Social Work. Both schools include live online classes as a key component of their online courses.  These live online classes are weekly classes hosted in Adobe Connect for 90-120 minutes for the duration of the semester and led by a course instructor with a teaching assistant facilitator.  Every class is supported by a dedicated webinar specialist.  During live online classes, students participate in a variety of ways, depending on the course needs and instructor preferences.  Participation can happen via chat, in multiple choice and short-answer polls, via mics, via webcams, via status icons, and in small group breakout activities.  Every course is unique.

    During the session, participants had the opportunity to share their own strategies, ask questions of each other and of the presenter, and add to their toolkits of online institutional strategies.
