Safety In Children With Medical Complexity: Our Canaries In The Coal Mine?, Christine A. Schindler, Elisabeth S. Pordes, Steven D. Finkenbinder, K. Jane Lee

College of Nursing Faculty Research and Publications

Purpose of review

The goal of this paper is to describe the complicated and diverse safety risks facing children with medical complexity.

Recent findings

Children with medical complexity have an increased risk of experiencing adverse health outcomes related to multiple comorbidities, the complicated nature of their care, and frequent interactions with the health care system. The safety risks experienced by children with medical complexity are in large part due to the complex nature of their care rather than the specific risks posed by the complicated nature of their illnesses.

Summary

The complicated nature of care for children with medical complexity …

Access To The Healthcare System For Acb People Living In Waterloo Region, Ontario: A Racial And Socio-Ecological Examination, Tiyondah Fante-Coleman

Theses and Dissertations (Comprehensive)

Little research has investigated the barriers and facilitators to accessing healthcare for African, Caribbean, and Black people in Canada. This thesis identifies barriers and facilitators using a socio-ecological framework in two papers. Five focus groups were held with 22 ACB participants in Waterloo, Ontario. Thematic analysis guidelines informed the analysis of focus group data. The first paper identified barriers at the social (racism and employment, immigrant status) and institutional (wait times, out-of-pocket expenses) levels. Community connections was the sole facilitator at the social level. The second paper identified four barriers at the interpersonal level: physicians’ style of care, lack of …

Border Disorder: 'Irregular Bangladeshis', Xenophobia And Crimmigration Control In India, Sujata Ramachandran

Theses and Dissertations (Comprehensive)

In India, the crisis of migration tied to the entry, presence and assimilation of the so-called ‘irregular’, ‘illegal Bangladeshi migrants’ is now an undisputed reality, seemingly affecting all geographical areas located within the national territories in multiple adverse ways. A decidedly strident xenophobic rhetoric attaches the presence of such migrants in an indiscriminate fashion to unending anxieties and urgent problems, whilst constantly drawing attention to the inefficacies of immigration enforcement and deficiencies of (interior and exterior) borders controls. This dissertation addresses key moments in the making and deepening of this national crisis and its management by state authorities over the …

Functional Characterization Of O-Acetyltransferase Wssi: Role In Bacterial Cellulose Acetylation Of Achromobacter Insuavis And Pseudomonas Fluorescens, Alysha Burnett

Theses and Dissertations (Comprehensive)

Cellulose biofilms consist of a community of bacterial cells encased in a self-produced matrix of polymers (e.g. exopolysaccharides, such as cellulose) that facilitate a firm adherence to surfaces. The acetylation (addition of an acetyl group on carbohydrates) is crucial in virulence; thereby in some cases allowing opportunistic bacteria to cause harmful diseases. Pertaining to this research, the wrinkly spreader (WS) genotype of Pseudomonas fluorescens colonizes the air-liquid interface on food, water sources and human tissue to form a robust biofilm with the ability to spread across surfaces. The composition of this biofilm largely consists of bacterial cellulose polymers …

Never Seen Before--Again: Aesthetic Adaptation And Transmedia Storytelling Networks In The Age Of Digital Cinema, Mike Mccleary

Theses and Dissertations (Comprehensive)

The primary purpose of this study is to re-evaluate the theorization of the narrative/non-narrative divide in cinema because there is still far too much rich information that is being lost in the chasm left between these two positions, particularly when it comes to the study of spectacular imagery. Working beyond the binary construction of a narrative/non-narrative divide allows for a more nuanced and dynamic analysis of the information that is conveyed by the cinematic image and, more specifically, by way of its aesthetic design. By no means is this study championing image over story or any other such formulation; rather …

Dispersal As A Buffer Against Zooplankton Community Change In Response To Fluctuating Salinity Levels On The Great Plains, Mercedes Huynh

Theses and Dissertations (Comprehensive)

The North American Great Plains is home to thousands of closed-basin lakes that are sensitive to changes in hydrology. Climate change models predict increased aridity in this region over the coming century, which is expected to lead to higher salinity levels in many freshwater lakes. Increases in salinity levels may impact zooplankton communities, as laboratory experiments show that many freshwater species have a low tolerance for elevated salinity levels, and field data demonstrate that salinity is the primary factor structuring aquatic communities on the Great Plains. Changes to zooplankton communities could lead to a trophic cascade based on their important …

The Mockery Of Things: Material Culture And Domestic Ideology In The Detective Fiction Of Anna Katharine Green, Claire Meldrum

Theses and Dissertations (Comprehensive)

The Mockery of Things: Material Culture and Domestic Ideology in the Detective Fiction of Anna Katharine Green examines how a popular genre author like Anna Katharine Green (1846-1935) uses objects to articulate middle-class identity and social constructions in late-nineteenth-century and early twentieth-century America. During that era, the home as both a physical space and an ideological signifier was a central tenet in American middle-class identity. Focusing on domestically situated objects – clothing, household furnishings and domestic architecture – this dissertation considers how such items, which have tended to be read in support of domestic identity, instead function within the context …

Going Back To The Soil: An Integrated Approach To Farming., Renée V. Christie

Theses and Dissertations (Comprehensive)

Agricultural productivity is often constrained by nutrient availability; as such, copious amounts of synthetic fertilizers are applied to maintain productivity. However, the intensive use of synthetic fertilizers has reduced the capacity of the soil to carry out crucial roles such as nutrient cycling because of shifts in the microbial community composition and structure. In addition, much of the applied synthetic fertilizers become lost to the environment through run-off, which contributes to soil degradation. With the increasing demand on agricultural systems to provide food and fibre and the adverse impacts of agricultural production on the soil resource, amendments that support soil …

Expression Of Alternative Oxidase In The Copepod T. Californicus When Exposed To Environmental Stressors, Carly Tward

Theses and Dissertations (Comprehensive)

In addition to the typical electron transport system in animal mitochondria responsible for oxidative phosphorylation, some species possess an alternative oxidase (AOX) pathway, which causes electrons to bypass proton pumping complexes. Although AOX appears to be energetically wasteful, studies have revealed its wide taxonomic distribution, and indicate it plays a role in environmental stress tolerance. AOX discovery in animals is recent, and further research into its expression, regulation, and physiological role has been impeded by the lack of an experimental model organism. DNA database searches using bioinformatics revealed an AOX sequence present in the arthropod Tigriopus californicus. Multiple sequence …

Factors Affecting Biofilm Formation In Oral Pathogenic Bacteria Of The Red Complex, Sidney Nechacov

Theses and Dissertations (Comprehensive)

Periodontal disease, also known as periodontitis, is a dental disease that is estimated to affect 2.4 billion people worldwide. This disease is characterized by chronic inflammation and bleeding of gums, as well as loss of tooth bone density. Currently, treatments for the disease include dental surgeries and various types of antibiotics, but few are targeted specifically at the Red Complex bacteria which are strongly associated with chronic periodontitis. The Red Complex consists of three bacteria: Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola. Each of these bacteria, are anaerobic oral pathogens that reside in the subgingival pocket adjacent to …

Connectedness To Nature And Pro-Environmental Behaviour From Early Adolescence To Adulthood: A Comparison Of Urban And Rural Canada, Daniel Anderson

Theses and Dissertations (Comprehensive)

Previous research has demonstrated that emotional connectedness to nature (ECN) is one of the strongest predictors of pro-environmental behaviour (PEB). This study investigated the influence of age, gender and living context on ECN and PEB in two Canadian samples.

Study participants completed an environmental survey, which assessed demographic data as well as their levels of ECN and PEB. Project I, which contained 1251 participants, investigated what group factors (age, urban vs. rural living context, male vs. female) contributed to ECN and PEB, as well as whether ECN mediated the relationship between age and PEB. Project II, which contained 84 adolescents, …

The Effect Of Loading Rate On Annulus Fibrosus Strength Following Endplate Fracture, John Mcmorran

Theses and Dissertations (Comprehensive)

Low back pain is the most prevalent cause of chronic pain for North Americans, and its correlation with endplate damage, and deficient mechanical properties in the annulus fibrosus (AF) makes this injury particularly concerning. To date, biomechanical alterations in the AF following endplate fracture have not been well described. Owing to the AF’s collagenous composition, and the intrinsic biomechanics of intervertebral discs (IVDs) during compression, it was hypothesized that the mechanical properties of AF specimens would show rate-dependent alterations in their tensile and adhesive strengths following endplate fracture. The purpose of the present study was to quantify the mechanical properties …

Does Perceived Ecological Integrity Affect Restorative Health Outcomes? An Examination Of Visitor Experiences In Diverse Environments In An Ontario Protected Area, Catherine E. Reining

Theses and Dissertations (Comprehensive)

The human health and well-being benefits associated with nature contact is well established. Parks and other forms of protected areas contribute significantly to these benefits by providing access to nature. However, limited research has been done on how different environments within protected areas (e.g., forests, coasts, areas being restored) and the perceived quality (i.e., ecological integrity) of these environments affect the health and well-being outcomes of visitors. This study builds on previous work to better understand how visitor experiences provided by diverse natural and built environments in Pinery Provincial Park affect perceived restorative outcomes as one aspect of health and …

Factors Influencing Zooplankton Communities In Small Arctic Lakes, Northwest Territories, Jasmina Vucic

Theses and Dissertations (Comprehensive)

The Canadian Arctic has been warming at an unprecedented rate, causing significant changes to the environment. At the same time, continued development in the north has increased the demand for gravel extraction used to construct and maintain infrastructure such as highways. The development of roadways and gradual loss of permafrost in Canada’s north has led to changes in water quality, including increased calcium, conductivity, and nutrients. In addition, gravel extraction has led to the formation of artificial gravel pit lakes. Research has yet to determine how physical and chemical changes associated with development and permafrost thaw might impact zooplankton, and …

Helping Those Who Are Like Me: Highlighting Similarities To Elicit Empathy In Narcissists, Alys Yijun Zhao, Christian H. Jordan

Theses and Dissertations (Comprehensive)

Previous research suggests that narcissists (compared to less narcissistic individuals) lack empathy toward others unless specifically instructed to take others’ perspectives. But are narcissists capable of spontaneously empathizing with others without the need for instructed perspective-taking? Three studies addressed this question. Study 1 (Study 1a; N = 232 & Study 1b; N = 488) examined whether manipulating a target person’s level of narcissism (i.e., non-narcissistic, moderately-narcissistic, or highly-narcissistic) encouraged more empathy toward more narcissistic targets, who described a difficult romantic breakup, from more narcissistic participants. Study 2 (N = 590) used the same procedure and further examined whether target …

The Influences Of Culture And The Self On Children’S Memory Encoding And Delayed Retrieval, Hongyuan Qi

Theses and Dissertations (Comprehensive)

Culture and the self form a dynamic system that shapes children’s memories. However, how these two constructs influence specific memory processes still requires further investigation. The present dissertation contains four studies that examined the influences of cultural backgrounds and self-views on children’s memory encoding and delayed retrieval. Participants across four studies were recruited in the year range of 2016 to 2018. A total of 243 Grade 1 and 2 (the younger group) and Grade 3 and 4 (the older group) children participated, with an age range of seven to ten years. Specifically, 121 Chinese children were from Mainland China and …

Neurogenesis And Hippocampus- And Olfactory-Dependent Learning In The Goto-Kakizaki Rat, Alanna Chalk

Theses and Dissertations (Comprehensive)

Research suggests that the chronic hyperglycemia associated with type 2 diabetes impairs brain function a number of ways – including a reduction in adult neurogenesis in the dentate gyrus (Beaquis et al., 2009; Lang et al., 2009;) and olfactory bulb (Lang et al., 2009; Ramos-Rodriguez et al., 2014). To investigate these impairments, Goto-Kakizaki (GK) rats were tested in both a radial arm maze and the social transmission of food preference (STFP), behaviours that depend on the integrity of the dentate gyrus and olfactory bulb, sites of profound adult neurogenesis (Altman & Das, 1965; Galef and Wigmore, 1983; Morris et al., …

Blurred Lines: A Phenomenological Study Of Maternal-Child Interconnection., Laura Macgregor

Theses and Dissertations (Comprehensive)

This phenomenological study explored the lived experiences of maternal-child interconnection among 12 mothers raising children, of any age, with developmental disabilities as well communication challenges. During semistructured interviews, mothers told stories of maternal-child interconnection that described a sacred, mutual, and unique interpenetration of experiences between mother and child that was nurtured and sustained by ongoing togetherness. Mothers also shared that their unique mother-child interconnection was difficult to articulate, and often poorly understood beyond the mother-child dyad.

Maternal-child interconnection allowed mothers to understand their children’s unique, often non-verbal communication. As a result, mothers of children with significant communication challenges were able …

Rationality In Bargaining By Finite Automata, Jim Bell

Theses and Dissertations (Comprehensive)

Aspects of behavioral decision-making can be integrated into game-theoretic models of two-player bargaining using finite automata which can represent bargaining strategies in combination with various behavioral traits. The automata are used as bargaining agents who must jointly agree upon a fixed allocation of transferable utility in an infinite-horizon Rubinstein bargaining game. At each turn, the automata are given the opportunity to accept a proposed portion of the transferable utility, or to reject the proposal and make a counter-offer of their own. A round-robin tournament and ecological simulations were run to explore strategic dominance under different conditions. Principles of bargaining strategy …

Trophic Position And Foraging Ecology Of Ross, Weddell, And Crabeater Seals Revealed By Compound-Specific Isotope Analysis, Emily K. Brault, Paul L. Koch, Daniel P. Costa, Matthew D. Mccarthy, Luis A. Hückstädt, Kimberly Goetz, Kelton W. Mcmahon, Michael G. Goebel, Olle Karlsson, Jonas Teilmann, Tero Härkönen, Karin Hårding

Graduate School of Oceanography Faculty Publications

Ross seals Ommatophoca rossii are one of the least studied marine mammals, with little known about their foraging ecology. Research to date using bulk stable isotope analysis suggests that Ross seals have a trophic position intermediate between that of Weddell Leptonychotes weddellii and crabeater Lobodon carcinophaga seals. However, consumer bulk stable isotope values not only reflect trophic dynamics, but also variations in baseline isotope values, which can be substantial. We used compound-specific isotope analysis of amino acids (CSI-AA) to separate isotopic effects of a shifting baseline versus trophic structure on the foraging ecology of these ecologically important Antarctic pinnipeds. We …

Crisis-Driven Tax Law: The Case Of Section 382, Albert H. Choi, Quinn Curtis, Andrew T. Hayashi

Articles

At the peak of the 2008 financial crisis, the Internal Revenue Service (IRS) issued Notice 2008–83 (the Notice), administrative guidance that limited Internal Revenue Code (the Code) section 382, an important tax rule designed to discourage tax-motivated acquisitions. Although styled as a mere interpretation of existing law, the Notice has been widely viewed as an improper exercise of the IRS’s authority that undermined its legitimacy. But did the Notice work? There were many extraordinary interventions during the financial crisis that raised questions about eroding the rule of law and the long-term destabilizing effects of bail­outs. In a financial crisis, regulators …

Religious Slaughter And Animal Welfare Revisited: Cjeu, Liga Van Moskeeen En Islamitische Organisaties Provincie Antwerpen (2018), Anne Peters

Articles

The article comments on a Grand Chamber judgment by the Court of the European Union on animal slaughter according to Islamic prescriptions. The relevant European Union laws prescribe that religious slaughter without stunning of the animal may only take place in approved slaughterhouses. This causes a shortage during the Muslim Feast of Sacrifice in the Belgian province ofAntwerp. The EU law provisions are in conformity with the animal welfare mainstreaming clause of the Treaty on the Functioning of the European Union. Moreover, the EU regulation and its application in the concrete case does not violate the fundamental right of free …

Not Enough: Human Rights In An Unequal World, Harlan G. Cohen

Faculty Scholarship

Many will read Samuel Moyn’s powerful history of the quest for social and material justice as an intended wake-up call. Rather than as a blaring alarm though, Not Enough is better read as an invitation to dream.

Cgi (Computer Generated Imagery) Matrix Multiplication Activity, Cynthia J. Huffman Ph.D.

Open Educational Resources - Math

Many students are motivated by real world applications of mathematics, and most students are familiar with the term CGI from watching movies and playing video games. This particular activity ties matrix multiplication to CGI (Computer Generated Imagery). It has been used successfully with high school students in an Algebra II course who had just learned how to do matrix multiplication, middle school and high school students (some of whom were seeing matrix multiplication for the first time) attending a special Math Day on a university campus, and with College Algebra students (during a unit about matrices).

Demographic Response Of The Gambian Gerbil To Seasonal Changes In Savannah Fallow Fields, Safianu Rabiu, Robert K. Rose

Biological Sciences Faculty Publications

The Savannah gerbil, Gerbilliscus gambianus (Muridae: Gerbillinae) is important to the ecological relations of the dry grassland ecosystem of West Africa, as well as, being a zoonotic agent of human diseases and po-tential crop pest. We examined the impact of seasonal changes on the population dynamics of G. gambianus in northern Nigeria, by completing population estimates using capture–mark–recapture (CMR) and indirect population density indices (PDI) methods. The latter included fecal pellet counts and limited spotlightening. During 1990–1992 we collected both CMR and PDI data, and established their relationship by regression, thus calibrating the PDI values to CMR estimator. We also …

Serological Proteomic Screening And Evaluation Of A Recombinant Egg Antigen For The Diagnosis Of Low-Intensity Schistosoma Mansoni Infections In Endemic Area In Brazil, Vanessa Silva-Moraes, Lisa Marie Shollenberger, William Castro-Borges, Ana Lucia Teles Rabello, Donald A.

Background

Despite decades of use of control programs, schistosomiasis remains a global public health problem. To further reduce prevalence and intensity of infection, or to achieve the goal of elimination in low-endemic areas, there needs to be better diagnostic tools to detect low-intensity infections in low-endemic areas in Brazil. The rationale for development of new diagnostic tools is that the current standard test Kato-Katz (KK) is not sensitive enough to detect low-intensity infections in low-endemic areas. In order to develop new diagnostic tools, we employed a proteomics approach to identify biomarkers associated with schistosome-specific immune responses in hopes of developing …

Prime-Boost Vaccine Regimen For Sjtpl And Sjc23 Schistosome Vaccines, Increases Efficacy In Water Buffalo In A Field Trial In China, Akram A. Da'dara, Changlin Li, Xinling Yu, Mao Zheng, Jie Zhou, Lisa M. Shollenberger, Yue-Sheng Li, Donald A. Ham

Biological Sciences Faculty Publications

Schistosomiasis remains a serious zoonotic disease in China and the Philippines. Water buffalo and cattle account for the majority of transmission. Vaccination of water buffalo is considered a key strategy to reduce disease prevalence. Previously, we showed that vaccination of water buffalo with SjC23 or SjCTPI plasmid DNA vaccines, induced 50% efficacy to challenge infection. Here, we evaluated several parameters to determine if we can develop a two dose vaccine that maintains the efficacy of the three dose vaccine. We performed four trials evaluating: (1) lab produced vs. GLP grade vaccines, (2) varying the time between prime and boost, (3) …

Mapping Status And Conservation Of Global At-Risk Marine Biodiversity, Casey C. O'Hara, Juan Carlos Villaseñor-Derbez, Gina M. Ralph, Benjamin S. Halpern

Biological Sciences Faculty Publications

To conserve marine biodiversity, we must first understand the spatial distribution and status of at‐risk biodiversity. We combined range maps and conservation status for 5,291 marine species to map the global distribution of extinction risk of marine biodiversity. We find that for 83% of the ocean, >25% of assessed species are considered threatened, and 15% of the ocean shows >50% of assessed species threatened when weighting for range‐limited species. By comparing mean extinction risk of marine biodiversity to no‐take marine reserve placement, we identify regions where reserves preferentially afford proactive protection (i.e., preserving low‐risk areas) or reactive protection (i.e., mitigating …

Parasitic Dinoflagellate Hematodinium Perezi Prevalence In Larval And Juvenile Blue Crabs Callinectes Sapidus From Coastal Bays Of Virginia, H. J. Small, J. P. Huchin-Mian, K. S. Reece, K. M. Pagenkopp Lohan, Mark J. Butler Iv, J. D. Shields

Biological Sciences Faculty Publications

The parasitic dinoflagellate Hematodinium perezi infects the American blue crab Callinectes sapidus and other decapods along the Eastern seaboard and Gulf of Mexico coast of the USA. Large juvenile and adult blue crabs experience high mortality during seasonal outbreaks of H. perezi, but less is known about its presence in the early life history stages of this host. We determined the prevalence of H. perezi in megalopae and early benthic juvenile crabs from multiple locations along the Virginia portion of the Delmarva Peninsula. The DNA of H. perezi was not detected in any megalopae collected from several locations within …
