title: An Environmental Scan and Decision Tool for Menstrual Product Programs Selecting Free Vend Dispensers
Creators: name: Revington, Jessica Evelyn

Subjects: subject: Public Health
subject: Health Sciences

description: This study describes the results of a comparative environmental scan used to investigate and characterize (a) the structural and operational characteristics of menstrual product dispensers compatible with free menstrual product programs, and (b) the companies involved in manufacturing, selling, and distributing these dispensers. A structured online search led to the identification of 38 companies distributing 96 free vend menstrual product dispensers. Three key design considerations emerged from our comparison of various dispenser features: the type(s) of products dispensed, overall dispenser capacity, and dispensing modality. Most dispensers were capable of dispensing at least two menstrual product options. Overall dispenser capacity varied considerably between models, suggesting a lack of consistency in dispenser sizing. The free menstrual product dispensers captured in our search employed a wide variety of dispensing modalities. Few dispensers were designed as open-air access, suggesting that some form of control over product dispensing may be a preferred design characteristic for companies and/or prospective purchasers. Companies exclusively offering products related to menstruation and menstrual management appeared to demonstrate broader support for menstrual equity initiatives (e.g., statements, donations, formal partnerships, education, advocacy), especially when compared to companies offering free menstrual product dispensers as part of a larger inventory of products unrelated to menstruation. Finally, results from the environmental scan informed the development of a decision tool intended to support program administrators in selecting dispensers that best fit their program’s needs. This decision tool provides a novel structure for program administrators to compare and consider the various characteristics of the companies and free vend dispensers they may choose to use in their respective menstrual equity initiatives. To our knowledge, no other tools currently exist to support program administrators involved in these purchasing decisions, which is especially important since the burden of researching, comparing, and selecting program infrastructure is often downloaded onto program administrators without clear directives or guidance, creating a clear gap that may be filled by the novel structure and decision framework provided by this tool.

description: Communication skills are assessed by medically-enculturated examiners using consensus frameworks which were developed with limited patient involvement. Assessments consequently risk rewarding performance which incompletely serves patients’ authentic communication needs. Whilst regulators require patient involvement in assessment, little is known about how this can be achieved. We aimed to explore patients’ perceptions of students’ communication skills, examiner feedback and potential roles for patients in assessment. Using constructivist grounded theory we performed cognitive stimulated, semi-structured interviews with patients who watched videos of student performances in communication-focused OSCE stations and read corresponding examiner feedback. Data were analysed using grounded theory methods. A disconnect occurred between participants’ and examiners’ views of students’ communication skills. Whilst patients frequently commented on students’ use of medical terminology, examiners omitted to mention this in feedback. Patients’ judgements of students’ performances varied widely, reflecting different preferences and beliefs. Participants viewed variability as an opportunity for students to learn from diverse lived experiences. Participants perceived a variety of roles to enhance assessment authenticity. Integrating patients into communications skills assessments could help to highlight deficiencies in students’ communication which medically-enculturated examiners may miss. Overcoming the challenges inherent to this is likely to enhance graduates’ preparedness for practice.

description: We formalize a framework for quantitatively assessing agreement between two datasets that are assumed to come from two distinct data generating mechanisms. We propose a methodology for prediction scoring which provides a measure of the distance between two unobserved data generating mechanisms (DGMs), along the dimension of a particular model. The cross-validated scores can be used to evaluate preregistered hypotheses and to perform model validation in the face of complex statistical models. Using human behavior data from the Next Generation Social Science (NGS2) program, we demonstrate that prediction scores can be used as model assessment tools and that they can reveal insights based on data collected from different populations and across different settings. Our proposed cross-validated prediction scores are capable of quantifying true differences between data generating mechanisms, allow for the validation and assessment of complex models, and serve as valuable tools for reproducible research.

description: One of the key problems facing superconducting qubits and other Josephson junction devices is the decohering effects of bi-stable material defects. Although a variety of phenomenological models exist, the true microscopic origin of these defects remains elusive. For the first time we show that these defects may arise from delocalisation of the atomic position of the oxygen in the oxide forming the Josephson junction barrier. Using a microscopic model, we compute experimentally observable parameters for phase qubits. Such defects are charge neutral but have non-zero response to both applied electric field and strain. This may explain the observed long coherence time of two-level defects in the presence of charge noise, while still coupling to the junction electric field and substrate phonons.

description: The robustification of statistical models has been a popular topic for decades. Statistical robustification and robust optimization are the two main approaches in the literature, where the former stabilizes the model output by removing the outlier points while the latter concerns more the outlier points in making the conservative decisions. This thesis develops a novel robust optimization perspective to robustify a class of binary classifiers. Our model considers the worst-case distribution within a pre-determined uncertainty ball that centers at the given benchmark distribution with the radius calculated as per the Wasserstein distance. We derive the tractable formulation for the general problem. When focusing on the support vector machine (SVM), the general problem boils down to an easy-to-solve second- order cone programming problem. The robustified SVM is then applied to synthetic data with and without contamination, and our simulation studies show that our robustified SVM model can outperform the classical SVM and the extreme empirical loss SVM models under many circumstances.

Subjects: Landownership; land tenure; community landownership; land data

description: This report is based on interviews with representatives of community organisations from across Scotland, providing insights into their use and experiences of land data transparency. The most significant issue faced by the rural communities represented was that of land availability and access. Challenges relating to land data included a lack of transparency regarding land user rights, expertise in gathering and interpreting land data, and communication (or miscommunication) between communities and landowners. These challenges often resulted in delays or protracted legal processes. Recommendations include that the proposed land management plans for large landholdings are a key mechanism for community engagement in land-use decision-making and increasing transparency of land data.

description: Often the correctness of a piece of information, is not easily verified; Alice holds an encryption of Bob's secret and in the absence of Bob's key she must trust that Bob shared the correct encryption with her. In a cryptographic setting it is assumed that some, possibly all, parties participating are untrustworthy adversaries. An important generalized adversary is an Honest-but-Curious (HBC) adversary, a legitimate participant in an interactive protocol, requiring two or more participants, who will not deviate from the defined protocol but will attempt to gain as much knowledge from legitimately received messages. In security-critical applications, it is likely that participants are not acting honestly (regarded as malicious). A zero-knowledge proof (ZKP) is a tool that enables the verification that all parties acted honestly (provided well formed messages). One fundamental ZKP is the Schnorr protocol for knowledge of a discrete logarithm (DL); the Schnorr Σ-protocol is a three-move public coin protocol between two named parties, the Prover (\Prover) and the Verifier (\Verifier). The class of all Σ-protocols has well-established analysis techniques enabling secure composition both in parallel and sequential applications. Scaling Σ-protocols efficiently is challenging, and techniques to reduce the cost of conjunctive composition of the same Σ-protocols exist in the form of batch verification and batched proofs. Batched proof techniques trade bits of security for speed and efficiency. Batching non-conjunctive logic with Σ-protocols forms the contribution of this work.

description: This thesis introduces an innovative approach for the rapid identification of randomized controlled trials (RCTs) and evaluation of the certainty of evidence within the context of a living systematic review and network meta-analysis. The first paper (Chapter 4) describes a living systematic review methodology that incorporates crowd-sourcing, machine learning and a web-based tool to streamline the identification and classification of RCTs, introducing a novel "studification" process to enhance review maintenance. The second paper (Chapter 5) presents a semi-automated method for evaluating the certainty of evidence derived from direct estimates within a Bayesian network meta-analysis framework, adhering to GRADE guidance. The study also addresses the assessment of indirectness at the study-specific level using online tools. The final paper (Chapter 6) extends this methodology to assess the certainty of evidence for indirect and mixed evidence separately. This is achieved through a semi-automated process that utilizes the concept of the contribution matrix to identify the first-order loop, highlighting the primary contributors to indirect estimate. Additionally, in accordance with GRADE recommendations, an automated approach for evaluating imprecision is developed. Overall, this thesis may enhance the efficiency of maintaining a living systematic review, offering a novel approach to semi-automate the evaluation of evidence certainty from Bayesian network meta-analysis models while adhering to GRADE guidelines. Applied to the context of early rheumatoid arthritis, the findings potentially have positive policy implications such as how fast reviews can be done for clinical practice guideline development.

description: The circular economy represents a powerful new paradigm for materials consumption and solid waste management. Instead of beginning with extraction and ending with waste, the circular economy begins with material already in use, or else material designed for iterative uses, moves through production and consumption, and into waste management, which secures a revived or altered source material, which in turn moves though production and consumption, and so on, over and over again. Achieving significant greenhouse gas reductions in this area requires widespread shifts in production and consumption toward what can be expressed succinctly in a familiar refrain: “reduce, reuse, recycle.” There are a number of legal pathways to achieving emissions reductions through materials consumption and solid waste management. Corporate governance as well as research and development of new materials can play a significant role, and significant advances can be made through regulatory interventions.

description: Recently, a new spin-1/2 fermionic quantum field with mass dimension one in four dimensions--Elko field $λ$ was introduced as a candidate of dark matter. In this paper, we investigate the localization of 5D Elko {spinors} on Minkowski branes by presenting the equation of {the} Elko KK modes. For the 5D free massless Elko field, the zero mode can be localized on Randall-Sundrum thin brane but can not be localized on the majority of thick branes. There {do} not exist bound massive KK modes on all these branes. If the 5D mass term is introduced, there will exist bound Elko zero mode in Randall-Sundrum brane model. And when we introduce the Yukawa type coupling $ηϕ^2 \mathop λ\limits^\negλ$ with $ϕ$ the background scalar field, the Elko zero mode can be localized on some special thick branes with a particular coupling constant $η$. Nevertheless, the massive KK modes still can not be localized on these branes. These results are very different from that of the conventional Dirac spinor {field} and the scalar field.

Our analysis shows that the gel can be tuned through three classes of dynamical states by increasing motor activity: a constant unstrained state of homogeneous density, a state where the local density exhibits sustained oscillations, and a steady-state which is spontaneously contracted, with a uniform mean density.

description: Scholarship on the Anthesteria, an Athenian festival held in late February and celebrated new wine in honour of the wine-god Dionysos, are at odds with how to interpret this festival, given that its various ceremonies contrasted each other in terms of their themes. Most notably the Anthesteria had joyous drinking festivities as well as a sacred wedding ritual between Dionysos and the basilinna (the archon basilieus’ wife). Held at this festival was also the morose Aiora ceremony, a rite wherein young Athenian women swung on makeshift swings to honour the death of the maiden Erigone. Given this contrast of the Anthesteria’s events, previous scholars, such as Walter Burkert, have demarcated the festival’s gloomy rites from its more cheerful and sacred rituals by placing them on separate days, which still encompassed the Anthesteria. More recent scholars, on the other hand, have excised the Aiora and holy wedding ceremony from the festival on the grounds that these two ceremonies are unrelated to the jovial and wine-centric events of the Anthesteria. Contradicting these scholars, my thesis offers an alternative interpretation of the Anthesteria, in which this festival could be both a gloomy and joyous occasion that was held on one day and hosted festive drinking events in conjunction with the gloomy Aiora ritual and sacred wedding ceremony. I shall argue that these seemingly contrasting events were interconnected and had a unifying purpose of ultimately promoting both agrarian and female fertility. As I discuss the fertility-promoting properties of the Anthesteria and its events, I shall compare this festival to Artemisian coming-of-age rites that promoted female fertility. Additionally, I will interpret this festival through the perspective of Hippocratic medicine, an interpretation overlooked by previous scholars, given that its ceremonies resemble Hippocratic treatments for gynaecological illnesses that affected a female’s fecundity.

Creators: name: Rahimof, Niloufar

Year: 2024

subject: Engineering--Chemical

description: Rate-transient analysis (RTA) is a widely used method for analyzing well production data to determine reservoir/fracture properties and fluid in place. However, applying RTA to unconventional reservoirs poses challenges due to their complex nature, which can lead to uncertain RTA model selection and property estimates. To address this problem, laboratory analysis of unconventional reservoir core samples using the rate-transient analysis porosity and permeability (RTAPK) method is performed. Unlike conventional laboratory methods, RTAPK is designed to reproduce conditions under which wells are produced in the field. Reservoir heterogeneities associated with unconventional reservoirs can impact RTA-derived flow-regime signatures and property estimates. Therefore, in this thesis, the impact of matrix laminations/bedding permeability heterogeneity orthogonal and parallel to flow on RTAPK- derived flow-regime signatures and permeability is studied. Another common problem facing RTA of field data is inter-well communication. Therefore, a second objective of this study is to explore the effect of inter-well communication on RTAPK-derived flow-regimes. A final objective is to explore the dynamic range of the RTAPK device. To achieve the thesis objectives, both natural rock and artificial core plugs are analyzed with RTAPK. Numerical simulation is also performed to verify experimental results. Log-log diagnostic plots are used to identify flow-regimes for homogeneous and heterogeneous natural and artificial samples using RTAPK. A deviation in the transition from transient linear to boundary-dominated flow is observed (relative to homogeneous samples) for core plug samples with laminations/bedding permeability heterogeneity, where flow in the core plug is orthogonal and parallel to laminations/bedding. Variability in permeability estimates derived using different RTA methods also implies the presence of heterogeneity. Artificial rock samples are successfully manufactured and used to verify the results obtained from natural samples. Furthermore, inter-well communication is replicated using the RTAPK device. Lastly, samples with permeabilities ranging from 10 nd to 100 μd are analyzed with RTAPK, suggesting that the dynamic range could span this range or more. This thesis demonstrates that the effects of rock heterogeneity and parent-child interference can be effectively studied in the laboratory, which in turn can be used to inform the analysis of field data.

Acad. des Se., 5 déc. 1881 ” and this is followed by Alcock (1895: 201). Rathbun (1925: 204) cited 1880 as the authority date for Scyramathia and this appears to be correct as the BL copy (call number AC. 424) of Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences Volume 91, sheets 33–58, pages 251–448, containing the paper of A. Milne-Edwards (1880b) is dated with a red British Museum Stamp “6 OC 80”. This availability date in London confirms Scyramathia A. Milne-Edwards, 1880. Furthermore, volume 7 of the Proceedings of the U.S. National Museum has the replacement name Anamathia S.I. Smith for the preoccupied Amathia Roux, 1828 and was actually published in 1885 (ICZN Opinion 712).

description: In refusal of the division and limitations inherent within both the authoritative, passive voice of conventional writing and the boundaries of western academic disciplines and knowledge production, this storied and relational work explores interconnections between identity, language, land, and story through the processes and methods of nehiyaw kehte kiskeyitamowin nitotisakewin (cree wisdom-seeking) or Indigenous wisdom-seeking. Drawing upon the trailblazing work of four Indigenous scholars from across kânata (Canada), the roles and responsibilities of good storytelling and storylistening are shared and demonstrated through mâmawapiwin (circle process), illuminating how theory, method, and practice are naturally braided together through âcimowin (story) within Indigenous research methodology. Through the sacred wisdom-seeking and story pathways of nehiyawewin (the cree language), nehiyaw kiskinohamakewina (the cree worldview), isihcikewin (ceremony), wâhkôhtowin (all my relations), wahkomitowin (relational accountability to the natural world), and miyo opihkinawâsowin (growing children well), this (re)stor(y)ing work creatively weaves together and preserves individual and collective stories of decolonizing, healing, and becoming. By absencing (hu)mankind while still presencing the impact of colonial systems that were never designed with most of us in mind, this (re)imagined reality seeks to instead center the teachers and teachings of kâwînaw askiy (mother earth) embedded within the storied and layered wisdom-seeking journey of sîpîwan (it becomes a river), as well as the before-during-continuing âcimowina (life stories) of five wisdom-seekers. Ultimately, this work hopes to inspire a collective commitment to healing justice and cultivating spaces where stories and beings can thrive and live miyo pimâtisiwin (the good life).
Emergence and stability of Majorana fermions in proximity-coupled topological insulator nanowires

Publisher: name: University of British Columbia
Year: 2012

description: A finite-length topological insulator nanowire, proximity-coupled to an ordinary bulk s-wave superconductor and subject to a longitudinal applied magnetic field is shown to realize a one-dimensional topological superconductor with an unpaired Majorana fermion localized at each end of the nanowire. Here we also show that the unpaired Majorana fermions persist in this system for any value of the chemical potential inside the bulk band gap of order 300 meV in Bi₂Se₃ by computing the Majorana number. From this calculation, we also show that the unpaired Majorana fermions persist when the magnetic flux through the nanowire cross-section deviates significantly from half flux quantum. Lastly, we demonstrate that the unpaired Majorana fermions persist in strongly disordered wires with fluctuations in the on-site potential ranging in magnitude up to the size of the bulk band gap. These results suggest this solid-state system should exhibit unpaired Majorana fermions under accessible conditions likely important for experimental study or future applications.

description: A connection between kinetic processes and intermittent turbulence is observed in the solar wind plasma using measurements from the Wind spacecraft at 1 AU. In particular, kinetic effects such as temperature anisotropy and plasma heating are concentrated near coherent structures, such as current sheets, which are non-uniformly distributed in space. Furthermore, these coherent structures are preferentially found in plasma unstable to the mirror and firehose instabilities. The inhomogeneous heating in these regions, which is present in both the magnetic field parallel and perpendicular temperature components, results in protons at least 3-4 times hotter than under typical stable plasma conditions. These results offer a new understanding of kinetic processes in a turbulent regime, where linear Vlasov theory is not sufficient to explain the inhomogeneous plasma dynamics operating near non-Gaussian structures.

description: Objective: Pediatric chronic pain is prevalent and can significantly interfere with children’s physical, emotional, social, and educational functioning. Parent factors have been shown to play an important role in children’s chronic pain; however, research has predominately focused on parent responses to child pain to the exclusion of parents’ own functioning (i.e., their physical and mental health). The broad aim of this dissertation was to examine the association between parent functioning, specifically their own chronic pain and mental health symptoms, and child chronic pain using a multi-method approach. Methods: Three studies were conducted. The first study was a systematic review and meta-analysis of the extant literature examining associations between parent mental health and children’s chronic pain and related functioning in both clinical and community samples. The second study used daily diary data from a clinical sample of 76 youth referred to a tertiary pain program and one of their parents to examine the associations between parent chronic pain status, parent daily variability (in their anxiety, mood, protective responses, and parenting stress), and youth daily pain intensity and interference. The third study used data from 1128 mother-child dyads enrolled in a longitudinal, community-based cohort study to identify risk and resilience factors throughout childhood that moderated the intergenerational transmission of chronic pain. Results: Poorer functioning (i.e., chronic pain and/or mental health problems) in parents was significantly associated with the presence of chronic pain in community samples of children as well as the pain-related functioning of clinical samples of children with chronic pain. Parent chronic pain and mental health symptoms were related to children’s chronic pain and functioning in distinct as well as interacting ways. Several general parent and child factors were found to contribute to the association between parent functioning and child chronic pain, either increasing or decreasing the strength of the association, including ineffective parenting practices, child optimism, and child connections with adults. Conclusions: Parent functioning plays an important role in pediatric chronic pain, increasing children’s risk for poor adaptation to chronic pain, and should be more widely considered in research and clinical interventions for pediatric chronic pain.

description: This supporting paper shares the process on which the thesis work is based, the theories which support the process, and the outcomes of Building Relationship with the Land. It asks how descendants of white settler who settled the prairies at the turn of the 19th Century can put aside the Western belief in human domination over the Land and live in relationship with the Land. The Earth's ecosystem is based on the interdependence of all species, including human; ignorance of this relationship has fostered destructive forces upon the Earth. At this juncture, how do settler descendants enter the Land that is alive and waiting to be met, understood and listened to? Finally, what role can art from a relational approach play in this process? Theoretical foundations of biophilia, phenomenology and spiritual ecology provide structure for an applied research approach using the fundamentals of relational aesthetics to formulate a path forward. Analysis of resulting data serves to shape future work in building relationship with the Land. Reviewing the work of two major artists whose work centers on audience engagement demonstrates the ability of knowledge dissemination to influence change and provides direction in taking this more more direct participatory approach. Two online organizations provide platforms for discourse and building depth for a participatory practice. Subsequent chapters detail the methodology, strategies and actions taken over a two-year period. Data analysis supports the importance of beginning with a sound theoretical basis and encouraging a process which can be adapted to a variety of situations. The participants' responses reinforce the role of contemplative approach to build a relationship with the Land and the importance of our own experiences through awakening the senses have in encouraging community discussion and dialogue. Building a relationship to the Land is one means to harness individual agency within community to create new narratives based on a common story that can lead to new answers.

description: Relating in situ measurements of relativistic solar particles to their parent activity in the corona requires understanding the magnetic structures that guide them from their acceleration site to the Earth. Relativistic particle events are observed at times of high solar activity, when transient magnetic structures such as Interplanetary Coronal Mass Ejections (ICMEs) often shape the interplanetary magnetic field (IMF). They may introduce interplanetary paths that are longer than nominal, and magnetic connections rooted far from the nominal Parker spiral. We present a detailed study of the IMF configurations during ten relativistic solar particle events of the 23rd activity cycle to elucidate the actual IMF configuration guiding the particles to Earth, where they are measured by neutron monitors. We use magnetic field (MAG) and plasma parameter measurements (SWEPAM) from ACE, and determine interplanetary path lengths of energetic particles through a modified version of the velocity dispersion analysis based on energetic particle measurements with SoHO/ERNE. We find that the majority (7/10) of the events is detected in the vicinity of an ICME. Their interplanetary path lengths are found to be longer (1.5-2.6 AU) than those of the two events propagating in the slow solar wind (1.3 AU). The largest apparent path length is found in an event within the fast solar wind, probably due to enhanced pitch angle scattering. The derived path lengths imply that the first energetic and relativistic protons are released at the Sun at the same time as electron beams emitting type III radio bursts. The timing of the first high-energy particle arrival at Earth is dominantly determined by the type of IMF in which the particles propagate. Initial arrival times are as expected from Parker's model in the slow solar wind, and significantly larger in or near transient structures such as ICMEs.

description: Gonoplax sinuatifrons Miers 1885: 588; 1886: 246, pl. XX, fig. 2.
 Remarks. Castro (2007) erected the monotypic Hadroplax to accomodate Gonoplax sinuatifrons Miers. In his synonymy he listed G. sinuatifrons (Miers 1885: 588) as a nomen nudum. The description of G. sinuatifrons by Miers (1885) stated “... very nearly allied to the common European Gonoplax rhomboides, and distinguished only by the sinuated frontal margin and shorter chelipeds”. This brief description makes the species name available and the “sinuated frontal margin” is among the characters listed by Castro (2007: 697) in his description of Hadroplax: “front slightly deflected ventrally, sinuous.”
 Valid as Hadroplax sinuatifrons (Miers, 1885).

description: Unequal transmission of nutritive signaling during cell division establishes fate disparity between sibling lymphocytes, but how asymmetric signaling becomes organized is not understood. We show that receptor-associated class I phosphatidylinositol 3-kinase (PI3K) signaling activity, indexed by phosphatidylinositol (3,4,5)-trisphosphate (PIP3) staining, is spatially restricted to the microtubule-organizing center and subsequently to one pole of the mitotic spindle in activated T and B lymphocytes. Asymmetric PI3K activity co-localizes with polarization of antigen receptor components implicated in class I PI3K signaling and with facultative glucose transporters whose trafficking is PI3K dependent and whose abundance marks cells destined for differentiation. Perturbation of class I PI3K activity disrupts asymmetry of upstream antigen receptors and downstream glucose transporter traffic. The roles of PI3K signaling in nutrient utilization, proliferation, and gene expression may have converged with the conserved role of PI3K signaling in cellular symmetry breaking to form a logic for regenerative lymphocyte divisions.

description: We study here dissipative properties of systems composed of two components one of which is highly lossy and the other is lossless. A principal result of our studies is that all the eigenmodes of such a system split into two distinct classes characterized as high-loss and low-loss. Interestingly, this splitting is more pronounced the higher the loss of the lossy component. In addition, the real frequencies of the high-loss eigenmodes can become very small and even can vanish entirely, which is the case of overdamping.

description: Our evolving society at present includes technology-enhanced online education, workplaces, and human service providers.  In this online environment, students, coworkers, and clients who do not see each other in person may be at risk of feeling a loss of community or a loss of support around holistic wellness.  Schools working in the field of online higher education, including online social work education programs, have created diverse approaches to supporting online student – faculty wellness.  These approaches may also be helpful for human service providers with virtual clients, organizations with remote employees, or consultants who lead virtual trainings.

Schools working in the field of online higher education, including online social work education programs, have created diverse approaches to supporting online student wellness.  In this session, the presenters will share examples of wellness-related programs from online higher educational institutions that can be applied with trainees, employees, and clients in human service organizations.  Participants will have the opportunity to take away innovative ideas from diverse higher educational settings, share their own ideas with other participants, and consider new wellness ideas for their programs in diverse organizational settings.

The purpose of this interactive workshop is to share current research and obtain rich and enlightening discussion from audience to develop innovative “online wellness” programs in diverse human service settings.  This session will be useful for educators and administrators working with online programs, managers who have virtual team members, clinicians or human service workers who have virtual clients, and anyone who leads online trainings or planning to initiative technology enhanced human service activities.

The session will draw on the presenters’ experiences incorporating wellness activities into their own online classrooms and programs, as well as their research in this area.

Interactivity for the session will include informal interactive polling with immediate polling results to gauge participants’ experiences and interests around the workshop topic, whole-group discussion questions to give the group the chance to share ideas, pair-share discussions to give participants the chance to consider how to apply the workshop content to their unique work environments, and time for Q&A.   The importance would be to involve all audience members in the discussion of online wellness practices and how supervisors and administrators can affect human connectedness and social wellbeing to online staff and clients in human service organizations.

description: Cystic fibrosis (CF) is a genetic disease characterised by frequent respiratory infections that exacerbate symptoms, leading to a decline in lung function and increased morbidity and mortality. Pseudomonas aeruginosa is considered the primary pathogen in CF, contributing significantly to disease severity. Stenotrophomonas maltophilia is an emerging pathogen of interest, associated with increased pulmonary exacerbations and lung function decline. This thesis aimed to explore the CF sputum microbiome of persons with CF (pwCF) uninfected with these pathogens and to determine if the risk of future acquisition and persistence of these pathogens is linked to microbiome structure and composition. Individuals who experienced an incident infection with either P. aeruginosa or S. maltophilia were identified, and compared to uninfected controls matched for sex, age (+/-2 years), and birth cohort. Individuals were included if our longitudinal whole sputum biobank contained cryopreserved samples from one year prior to infection (pre), at the time of culture-based identification of infection (at), and one year following infection (post). Infection outcomes were classified as chronic/persistent (pathogen culture-positive in ≥50% of cultures in the subsequent year) or transient. The microbial community composition was assessed using V3-V4 16S ribosomal RNA (rRNA) gene sequencing. Relative abundance data were verified using both pathogen-specific qPCR and total 16S rRNA-targeted qPCR to assess bacterial bioburden. Strains were typed using pulse-field gel electrophoresis to differentiate strain types and distinguish incident infection episodes. Results from this work showed that the microbial community of pwCF that eventually developed P. aeruginosa, or S. maltophilia incident infections differed from those who remained uninfected at the times of sampling. Additionally, at the time of infection, the microbial community composition differed between individuals with persistent infections and those whose infections were cleared. These findings suggest that the sputum microbiome in pwCF is associated with future infection risk and persistence, indicating its potential as a biomarker for prognosis and personalised treatment.
