description: Antibiotic use is an integral part of livestock farms, but their overuse or misuse may result in the occurrence of unsafe level of residues that cause deleterious health effects. A cross-sectional study was performed from December 10/2020 and January 15/2021 to detect and estimate the level of tetracycline, oxytetracycline and penicillin G residues in beef samples intended for public consumption at Dukem and Bishoftu towns, central Ethiopia. Muscle samples were randomly collected from butcheries. Residue levels were determined using liquid chromatography coupled with triple quadrupole mass spectrometer (LC- ESI-QqQ). From 100 beef samples analysed, 10 % contained detectable level of residues of oxytetracycline. It is distributed as 12 % (6/50) at Dukem and 8 % (4/50) at Bishoftu towns. Tetracycline as residue was detected only in one sample that was collected from Dukem, at 9.35 µg/kg simultaneously with oxytetracycline. However, penicillin G was not detected in any of the samples. The levels of oxytetracycline residues (in µg/kg) range from 18.9 to 26.1 at Dukem and from 7.63 to 19.73 at Bishoftu. The mean determined residue levels of oxytetracycline were 22.32 ± 2.38 µg/kg and 15.99 ± 13.2 µg/kg at the two towns, respectively. The levels were much lower than the Maximum Residue Limit (MRL) established for Tetracyclines (TCs) either by EU (100 μg/kg) or Codex (200 μg/kg) guidelines. The determined residue levels are minimum and thus minimizing health risks associated with their consumption, although their detection in few samples and their repeated ingestion might be still associated with a rising concern of antibiotic resistance. Thus, the beef in the study area was acceptable for public consumption with respect to the analyzed three antibiotics.
Mycobacterium avium subsp. paratuberculosis in a captive wood bison herd: diagnostics and disease dynamics overtime

description: Mycobacterium avium subsp. paratuberculosis (Map) has been identified in a wide range of domestic and wild ruminants. Captive wildlife can experience JD-related epidemiological scenarios similar to those in cattle. In wood bison (Bison bison athabascae), an iconic and keystone species in Canada, Map DNA has been reported in fecal samples from clinically healthy animals. However, there is apparently no published information regarding clinical presentation of JD and its significance in wood bison. The objective of this study was to determine to what extent Map can affects a captive bison herd located in northeastern Alberta, Canada. The first part of the study was the detection and isolation of Map in clinical cases. Necropsies were performed on six wood bison and 24 samples were collected from each bison. The highest frequency of positive samples was observed with tissue culture 62.5% (90/144) followed by F57/IS900 qPCR 43.1% (56/130), and histopathology 29% (38/131). Distal jejunum and its associated lymph nodes were the most reliable tissue samples for detecting Map, irrespective of tissue autolysis or absence of visible lesions. Strain typing revealed a type II (cattle) strain, second clade. The second part of the study focused on Map status in the herd by obtaining within-herd prevalence, evaluating the impact of a test and cull strategy and potential risk factors associated with Map. At the outset, within-herd prevalence was 4.7% based on IS900/F57 qPCR and 6.8% with IS900 qPCR with culture confirmation. The following year, after we calculated a 56.3% of culling rate of positive animals, the within herd prevalence observed by IS900/F57 qPCR was 4.2% and 9.9% by IS900 qPCR with culture confirmation. Bison in the age group ≥ 6-9 years were more likely to be Map positive. Furthermore, the location with the higher number of animals was significantly associated with being Map positive. Information from this study can contribute to control strategies in the bison herd studied, by obtaining the appropriate tissue samples selection at the necropsy and by targeting the age group most likely to be Map positive. Additionally, based on the prevalence obtained in this study, sampling size calculations can be performed to carry out studies at a herd level. However, it is important to understand that the best strategy to reduce the prevalence of JD depends on specific objectives and characteristics of each bison herd.

description: This thesis introduces two biomedical measurement systems utilizing the AD5934 impedance converter: a silicon photomultiplier (SiPM)-based low-light fiber photometry system for neural recordings in mice and a wireless electrochemical impedance spectroscopy (EIS) device designed for cortisol detection in human sweat. Despite their apparent differences, both systems share a common foundation—the AD5934 impedance converter chip, generating sinusoidal excitation signals and measuring corresponding system responses. Our fiber photometry system utilizes an SiPM as an alternative photodetector, addressing the power and sensitivity limitations of conventional counterparts. Additional optical excitation at an isosbestic point, often used for mitigating motion artifacts, was also used to correct for SiPM gain variations. Employing two impedance converters enables amplitude modulation with two carriers, which allows for distinguishing the main signal from the isosbestic control signal. Characterization tests confirmed the system's robustness to motion artifacts and temperature variations. In-vivo experiments demonstrated the system's functionality at significantly lower optical excitation powers comparing to commercial fiber photometry systems. In the EIS device, the AD5934 was used for its originally intended purpose of impedance spectroscopy. When used with a cortisol immunosensor, it can determine the concentration of cortisol in a sample by measuring its impedance at a range of frequencies. The device has a compact form-factor, and is wireless and battery-powered. Adaptive gain control was implemented to enhance the device's dynamic range. Characterization tests on resistors, capacitors, and electrochemical samples, and comparative experiments against a commercial potentiostat validated the system's suitability for cortisol concentration measurement. The device showed promise for adaptation into a wearable device for daily semi-continuous cortisol monitoring. The SiPM-based fiber photometry system and the compact EIS device stand as successful implementations of two biomedical measurement systems that benefit from the use of the AD5934 impedance converter chip. These two projects demonstrate the versatility of the AD5934 impedance converter, and meet their individual aims.

description: High redshift galaxies permit the study of the formation and evolution of X-ray binary populations on cosmological timescales, probing a wide range of metallicities and star-formation rates. In this paper, we present results from a large scale population synthesis study that models the X-ray binary populations from the first galaxies of the universe until today. We use as input to our modeling the Millennium II Cosmological Simulation and the updated semi-analytic galaxy catalog by Guo et al. (2011) to self-consistently account for the star formation history and metallicity evolution of the universe. Our modeling, which is constrained by the observed X-ray properties of local galaxies, gives predictions about the global scaling of emission from X-ray binary populations with properties such as star-formation rate and stellar mass, and the evolution of these relations with redshift. Our simulations show that the X-ray luminosity density (X-ray luminosity per unit volume) from X-ray binaries in our Universe today is dominated by low-mass X-ray binaries, and it is only at z>2.5 that high-mass X-ray binaries become dominant. We also find that there is a delay of ~1.1 Gyr between the peak of X-ray emissivity from low-mass Xray binaries (at z~2.1) and the peak of star-formation rate density (at z~3.1). The peak of the X-ray luminosity from high-mass X-ray binaries (at z~3.9), happens ~0.8 Gyr before the peak of the star-formation rate density, which is due to the metallicity evolution of the Universe.

description: Over the past decade, numerous reputable companies, including IBM, Google, Microsoft, and various startups, have invested substantial resources in industrial research on quantum computing and the development of quantum computers. These quantum computers rely on qubits, or quantum bits, as their fundamental components, with information transmission facilitated by low-power microwave fields. Consequently, achieving ultra-low-noise microwave amplification is of paramount importance for accurately measuring these microwave fields and determining qubit state information. Parametric amplification emerges as a highly effective technique for conducting precise microwave measurements on quantum circuits. Parametric amplification, featuring Josephson Junctions, has been a well-established method for some time. However, recent advancements have introduced kinetic inductance as a non-linear superconducting phenomenon, leading to improved parametric amplifier designs. This thesis delves into a study of superconducting resonators, which serve as the core component of kinetic-inductance parametric amplifiers.

description: We show that a smooth, small enough Cauchy datum launches a unique classical solution of the relativistic Vlasov-Darwin (RVD) system globally in time. A similar result is claimed in Comm. Math. Sci. 6, 749-764 (2008) following the work in Int. Mat. Res. Not. 57191, 1-31 (2006). Our proof does not require estimates derived from the conservation of the total energy, nor those previously given on the transverse component of the electric field. These estimates are crucial in the references cited above. Instead, we exploit the formulation of the RVD system in terms of the generalized space and momentum variables. By doing so, we produce a simple a-priori estimate on the transverse component of the electric field. We widen the functional space required for the Cauchy datum to extend the solution globally in time, and we improve decay estimates given in Comm. Math. Sci. 6, 749-764 (2008) on the electromagnetic field and its space derivatives. Our method extends the constructive proof presented in "Collisionless kinetic equations from astrophysics: The Vlasov-Poisson system. Handbook of Differential Equations: Evolutionary Equations, Vol.3, Elsevier, 2007" to solve the Cauchy problem for the Vlasov-Poisson system with a small initial datum.

description: Phosphonate metal-organic frameworks (MOFs) present potential candidates for functional materials due to their inherent structural stability and the capacity for synthetic manipulation. However, a trade-off often arises in the form of compromised crystallinity and structural predictability, which poses a significant hurdle in fabricating porous materials. This thesis focuses on an in-depth investigation into the synthetic approach and the performance of ordered chromium phosphonate MOFs concerning proton conduction and lithium extraction. An approach utilizing a hydrogen-bonded metal-organic framework (HMOF) intermediate was adopted to balance crystallinity and stability and evaluated thoroughly in Chapter 3. Salts made of hexaaquochromium(III) cations and phosphonate anions were dehydrated to form stable MOFs. Intriguingly, this method maintains partial structural crystallinity and engenders a varied pore size distribution during the thermal dehydration conversion step. This variability, in turn, affects the proton conductivity by providing different proton mobility efficiency, with as broad as two orders of magnitude in proton conduction among different MOFs. Chapter 4 explores the use of the HMOF to MOF strategy, focusing on the impact of reagent stoichiometry, ligand geometry, and binary solvent systems on proton conduction. It reveals that fine-tuning reactant stoichiometry is a viable method for enhancing proton mobility channels. The chapter also investigates how ligand geometry influences proton conductor performance, finding that more flexible structures maintain conductivity regardless of structural changes caused by water percolation. Additionally, it highlights the role of binary solvent systems in HMOF synthesis, noting that higher solvent content in HMOFs leads to lower crystallinity and reduced proton conduction after thermal dehydration, though the dehydration process itself minimally affects proton conductivity. Chapter 5 pivoted focus to explore the potential of chromium phosphonates as direct lithium extraction (DLE) adsorbents. To achieve optimal Li+ uptake capacity and selectivity, DLE adsorbents were designed to incorporate a Li+ favorable ’pocket’, templated during synthesis, along with a specific pore aperture for Li+ sieving. The study investigates the influence of pH, contact time, and concentration on adsorption, indicating a pseudo-second order kinetic model and monolayer chemisorption. Durability tests reveal these adsorbents maintain consistent uptake capacity and high stability.

description: Numbers of international undergraduate students enrolled in Canadian universities and colleges have grown from 22,000 in the year 2000 to 2.2 million in 2022. While international students embark on their post-secondary journey of discovery, we as educators also embark on a journey of discovery to explore how prepared we are to meet the international learning community's needs. This research focused on generating understanding around cultural preparedness in learning communities and the tools needed to support the educating community. For this inquiry, I drew from the transformative learning theoretical framework, guided by a qualitative research methodological approach and methods to utilize a three-phased research design of topic-based focus groups and interviews. In this study, I drew from seminal work and insights on culture. I defined a nuanced definition of cultural preparedness in adult learning settings, specifically at a public university in Western Canada. The findings suggest that cultural preparedness is a community-wide endeavour in collaboration with students, administration, educators and begins with understanding one’s positionality. Outcomes from this study may further help educators promote best practices related to internationalization at home in the 21st century. Key words: internationalization at home, educators, students, transformative learning, qualitative, cultural preparedness, global pandemic, COVID-19

description: Strengthening the Refugee Regime calls for enhancing responsibility sharing. Responsibility sharing was a central commitment in the New York Declaration for Refugees and Migrants. It also is a key commitment in the preamble to the landmark 1951 Refugee Convention. Countries of first refuge are promised that their providing refuge will be met by “international cooperation,” though without specifying its content. Yet, just as the 1951 Refugee Convention failed to define what international cooperation meant; so too the New York Declaration is – as was the Humanitarian Summit before it - long on principles; and short on specific commitments. Today, therefore, responsibility sharing, as Peter Sutherland has so aptly characterized it, amounts to “Responsibility by Proximity.” Neighboring countries such as Syria’s neighbors, Turkey, Lebanon and Jordan overwhelmingly serve as the refuge for Syrians who have managed to flee its devastating civil war. This means that globally the developing world, both relatively poor and home to so many of the world’s armed conflicts, also serves as the refuge for 86% of the world’s refugees … and it does so without adequate international funding (only 40% of the UNHCR appeal for the region was met in 2016).

description: In this paper two things are done. First, it is pointed out the existence of exact asymptotically flat, spherically symmetric black holes when a self interacting, minimally coupled scalar field is the source of the energy momentum of the Einstein equations in four dimensions. The scalar field potential is the recently found to be compatible with the hairy generalization of the Plebanski-Demianski solution of general relativity. This paper describes the spherically symmetric solutions that smoothly connect the Schwarzschild black hole with its hairy counterpart. The geometry and scalar field are everywhere regular except at the usual Schwarzschild like singularity inside the black hole. The scalar field energy momentum tensor satisfies the null energy condition in the static region of the spacetime. The first law holds when the parameters of the scalar field potential are fixed under thermodynamical variation. Secondly, it is shown that an extra, dimensionless parameter, present in the hairy solution, allows to modify the gravitational field of a spherically symmetric black hole in a remarkable way. When the dimensionless parameter is increased, the scalar field generates a flat gravitational potential, that however asymptotically matches the Schwarzschild gravitational field. Finally, it is shown that a positive cosmological constant can render the scalar field potential convex if the parameters are within a specific rank.

description: The study was carried out with the aim of estimating variability, heritability, and genetic advance for 196 sugarcane genotypes. Results of the analysis of variance identified a very highly significant variation among the genotypes in all the traits evaluated. Except for stalk length and single cane weight, all of the traits’ lowest and highest mean values were present within the genotypes from fuzz, indicating the wide ranges of variability within the genotypes. Except for single cane weight, the highest mean values for all the traits were seen within the genotypes of fuzz, implying greater genetic potential for the genotypes of fuzz for these traits. The number of sprouted buds, number of tillers, and cane yield had high genotypic and phenotypic coefficients of variation, heritability, and genetic advance as a percentage of the mean. This indicates the presence of high levels of heritable genetic variations for these traits, implying that these traits could be improved through phenotypic selection. The number of stalks, plant height, stalk length, internode length, stalk diameter, single cane weight, brix, and purity had high to moderate heritability with moderate to low genetic advance as percentages of the means. This indicates that the phenotypic expression of these traits is highly influenced by non-genetic factors. Thus, it could be difficult to directly improve these traits via phenotypic selection; instead, efforts should be directed toward better management practices. This study presents the first evidence for the existence of variability in the newly introduced sugarcane genotypes that should be exploited.

Six challenges were selected as the major constraints to livestock farming in Bangladesh: climate change and natural hazards, poor veterinary care, breeding and management resources, marketing and international trade, and the SARS-CoV-2 pandemic. Solutions to these challenges (such as hazardous weather shelters, intensified surveillance of biosecurity for farms and markets, and non-government, government, and private organizations working together to educate and assist farmers) must target specific regions where the solutions would have the greatest effect.
Professional learning communities and professional development
Creators: name: Kelly, Jennifer Lynn
Publisher: name: University of British Columbia
Year: 2012

description: This case study examines the concept and practice of participating in a professional learning community as a form of professional development by a group of teachers in an interior British Columbia school district. The reflections and discussions of this group of teachers-as-learning community are examined in order to understand how the subjects construct their realities relative to their involvement in a professional learning community. The transcripts from semi-structured interviews of the subjects, which were reflective in nature, were analyzed to determine patterns or themes. As a result, four main themes emerged: benefits of a professional learning community, isolationism, criteria for self-sustaining professional development, and suggestions for improvement. From the data it became evident there were many perceived benefits to participating in a professional learning community for this group of teachers, each surrounding the main aspect of collaborative learning. Interdependence among the group members was the most significant benefit of this professional development practice. Other beneficial characteristics of this form of professional development included shared leadership, a shared set of ideas and values to strive towards, perturbation-based learning, and continual motivation to develop professionally. This study has potential educational importance because it informs teachers and administrators about the practice of a group of teachers’ professional learning communities and corroborates their value in professional development. The concept of self-sustaining professional development is also discussed in the final chapter as a query regarding professional learning communities and their implicit value in the long-term.

description: Maintenance of reduced body weight is associated both with reduced energy expenditure per unit metabolic mass and increased hunger in mice and humans. Lowered circulating leptin concentration, due to decreased fat mass, provides a primary signal for this response. However, leptin deficient (Lepob/ob) mice (and leptin receptor deficient Zucker rats) reduce energy expenditure following weight reduction by a necessarily non-leptin dependent mechanisms. To identify these mechanisms, Lepob/ob mice were fed ad libitum (AL group; n = 21) or restricted to 3 kilocalories of chow per day (CR group, n = 21). After losing 20% of initial weight (in approximately 2 weeks), the CR mice were stabilized at 80% of initial body weight for two weeks by titrated refeeding, and then released from food restriction. CR mice conserved energy (-17% below predicted based on body mass and composition during the day; -52% at night); and, when released to ad libitum feeding, CR mice regained fat and lean mass (to AL levels) within 5 weeks. CR mice did so while their ad libitum caloric intake was equal to that of the AL animals. While calorically restricted, the CR mice had a significantly lower respiratory exchange ratio (RER = 0.89) compared to AL (0.94); after release to ad libitum feeding, RER was significantly higher (1.03) than in the AL group (0.93), consistent with their anabolic state. These results confirm that, in congenitally leptin deficient animals, leptin is not required for compensatory reduction in energy expenditure accompanying weight loss, but suggest that the hyperphagia of the weight-reduced state is leptin-dependent.

description: In recent years, college mental health has emerged as a contentious issue. Marked by a consistently high prevalence of mental illness among students and the escalating demand for services, many reports have suggested that college mental health is in crisis. Despite increased efforts to support students, there is little evidence suggesting that the mental health crisis in college campuses is abating. To understand the current landscape of college mental health, we conducted two studies. The first study was a critical review that delineates the process of medicalization and its effect on college mental health crises. We employed the framework of psychiatrization (Beeker et al., 2021) to conceptually unpack the dynamics between top agents (service providers, administrators, and programs) and bottom agents (students) and investigated their roles in the medicalization of college mental health. Our findings suggested that the active participation of both top and bottom agents has created a medicalizing looping effect, reinforcing the college mental health crisis. Our discussion centred on the need to initiate a critical dialogue in such environments. The second study examined how students’ etiological beliefs about depression influence their treatment perceptions and help-seeking intentions. Using an online survey, we collected responses from 201 students from Canada and the USA regarding their etiological beliefs, perceptions about antidepressants and counselling, and help-seeking intentions. The hierarchical regression analyses showed that students who endorsed biological explanations of depression were more likely to see the benefits of antidepressants and less likely to see the risks. Students endorsing psychosocial explanations of depression were more likely to seek help for their suicidal thoughts. Moreover, male students were less likely to see the benefits of antidepressants and more likely to see the risks of counselling than their female counterparts. Students with more depression symptoms were more likely to view counselling as risky and less likely to engage in help-seeking for both emotional problems and suicidal thoughts. Our discussion focused on ways to tailor treatment programs to promote help-seeking in depression. Finally, we discussed ways to improve college counselling and support the mental health needs of college students.

description: We recalculate, completely within the original BFKL approach and at the next-to-leading order, the jet vertex relevant for the production of Mueller-Navelet jets in proton collisions and of forward jets in DIS. We consider both processes with incoming quark and gluon. The starting point is the definition of quark and gluon impact factors in the BFKL approach. Following this procedure we show explicitly that all infrared divergences cancel when renormalized parton densities are considered. We compare our results for the vertex with the former calculation of Refs. [1,2] and, in the case of the quark contribution, clarify the discrepancy present in the literature.

description: The goal of the study is to understand successional changes in an understory plant community after clear-cut timber harvesting. The forest ecosystem is within the Southern Very Wet Hypermaritime biogeoclimatic subzone in the broader Coastal Western Hemlock zone along the west coast of Vancouver Island. The ecosystem is located in Huu-ay-aht First Nations traditional territory, and the subzone falls within various Nuu-chah-nulth First Nations traditional territories. A chronosequence was used to categorize various stages of forest growth in five successional stages: Regeneration, Immature, Thinning, Mature, and Old-growth. Forests censused ranged in age from 1 to 354 years old with old-growth stages described as stands over 250 years. The leaf cover and stem density of understory plant species were recorded within 83 subplots. These metrics were evaluated with regard to environmental variables (slope aspect, elevation, canopy openness, soil pH, A horizon depth, soil profile depth, tree basal area, tree stem density, ground moss cover, and bare ground cover) to determine which, if any, factors influenced understory species composition and structure. Out of 45 species identified, 19 are culturally significant plant species to the Nuu-chah-nulth First Nations. The species restricted to one successional stage were identified, with emphasis on opportunistic species in early stages and rare species in the Old-growth stage. There was a large decrease in many culturally significant species immediately after clearcutting. There was a large decrease in species (stem density, leaf cover, species richness, species diversity) from the Regeneration stage to the Thinning stage (1 to 80 years); however, these values steadily increased thereafter. Plant leaf cover and stem density were influenced by the amount of light reaching the understory. The natural disturbance regime that shade-tolerant plants are adapted to in these old-growth forests is small-scale gap formations, which clearcutting does not mimic. Timber harvesting options are recommended to better mimic the natural disturbance regime in this region, which is optimal for the understory species in this region. Many rare and culturally significant plant species were negatively impacted by clearcutting. Protecting rare plant species in old-growth forests is important for maintaining forest biodiversity and indigenous cultural practices in the future.
WeChatting American Politics: Misinformation, Polarization, and Immigrant Chinese Media

description: As the discussion surrounding misinformation and polarization takes center stage, one space that has been largely overlooked is the Chinese media sphere within the United States, where questionable content has garnered a loyal following among Chinese-speaking immigrants. While headlines with false claims such as “Illegal immigrant started wildfire in Sonoma County” mirror types of misinformation found in American, English-language media, what’s especially worrisome in information ecosystems like these is their central influence on the first-generation immigrant experience and integration with US society. Yet, they exist very much as unknown, parallel universes for most researchers, journalists, and media watchers. With the rise of conservatism among first-generation Chinese immigrants, one of the fastest growing populations in the United States, this media space—led by mobile platform WeChat—offers key clues to how political information and misinformation are constructed for and distributed among the emerging political constituency. This report sheds light on the nature of misinformation and political polarization in the WeChat news sphere. The conclusions drawn from this preliminary investigation into WeChat mirror more general challenges with misinformation and polarization in the digital news ecosystem, but also highlight the specificity of the information problem for the immigrant population.

description: We study the existence of periodic solutions of the non--autonomous periodic Lyness' recurrence u_{n+2}=(a_n+u_{n+1})/u_n, where {a_n} is a cycle with positive values a,b and with positive initial conditions. It is known that for a=b=1 all the sequences generated by this recurrence are 5-periodic. We prove that for each pair (a,b) different from (1,1) there are infinitely many initial conditions giving rise to periodic sequences, and that the family of recurrences have almost all the even periods. If a is not equal to b, then any odd period, except 1, appears.

description: Does immersion yield empathy? The aim of this report is to address the question of whether news media—in this instance, short-form journalistic stories—presented in a 360-degree video format affects a user’s empathetic response to the material. If so, what might the advantage of such a response be, and could it include improvement in a viewer’s ability to recall the content over time or a resulting behavioral change? Naturally, part of the study will deconstruct what we mean by such a nebulous term as “empathetic” and how exactly it can be measured. The study both investigates if particular audiences are likely to respond empathetically to certain narratives and analyzes the component parts of immersive experiences—comfort level, interactivity, and perceived amount of user agency—that contribute to producing an empathetic response. It also aims to answer whether the virtual reality (VR) format is better suited to particular stories or audiences, as well as the potential for unintended, antithetical effects in this embryonic medium such as a user’s perception of personal space invasion or the feeling that they are not looking in the right direction. Results from our study of 180 people viewing five-minute treatments comprised of either 360-degree video or text articles monitored user reactions and their sense of immersion on the day of their first exposure to the narrative treatment, as well as two and five weeks later.
