description: Domestic cats have a worldwide T. gondii seroprevalence of 30-40% and play pivotal roles in this parasite’s transmission: it reproduces sexually only in felid intestines, after which it is shed in their feces. Asymptomatic T. gondii infection is associated with bradyzoite-containing brain cysts that produce tyrosine hydroxylase. Elevated dopaminergic tone is thought to underlie increased locomotor, risk-averse, and exploratory behavior in many infected animals. However, the effect on cat behavior is unknown. We propose that latent T. gondii infection in domestic cats similarly alters their behavior to increase its spread. This follows from the well-supported ‘fecal-exposure’ hypothesis: if T. gondii mediates the size of a cat’s home range characteristics, then it will direct where soil is contaminated with T. gondii and influence parasite exposure in intermediate hosts and in cats with overlapping home ranges. Since many species have subtle behavior alterations following T. gondii infection, we are testing whether T. gondii alters behavioral characteristics of its definitive host. Specifically, we hypothesize that chronic T. gondii infection in domestic cats decreases their risk-averse behavior and leads to increased locomotor activity. We have built an on-line survey to assess understanding of T. gondii infection and risks and recruited owners of pet cats from the participants. We then cross-sectionally evaluated whether risk-aversion and locomotory activity in their pets differ by seropositive status. In one behavioral paradigm, cat behavior is recorded over a series of episodes with and without the owner. When the owner is present, s/he sits and interacts with their cat. After an initial set of familiarization episodes, a balanced scent-based paradigm is used to evaluate a risk-averse response. We demonstrate that this least-invasive paradigm is useful to infer behavioral changes that may result from alteration of dopamine tone via T. gondii infection. This work provides an understanding of how T. gondii infection impacts cat behaviors to influence parasite spread. It also contributes to a theoretical framework to understand the impact of the risk of infection by fecal-transmitted parasites in an ecologically relevant setting.

description: Vertical transmission of bacterial endosymbionts is accompanied by virtually irreversible gene loss that results in a progressive reduction in genome size. While the evolutionary processes of genome reduction have been well described in some terrestrial symbioses, they are less understood in marine systems where vertical transmission is rarely observed. The association between deep-sea vesicomyid clams and chemosynthetic Gammaproteobacteria is one example of maternally inherited symbioses in the ocean. Here, we assessed the contributions of drift, recombination and selection to genome evolution in two extant vesicomyid symbiont clades by comparing 15 representative symbiont genomes (1.017–1.586 Mb) to those of closely related bacteria and the hosts' mitochondria. Our analyses suggest that drift is a significant force driving genome evolution in vesicomyid symbionts, though selection and interspecific recombination appear to be critical for maintaining symbiont functional integrity and creating divergent patterns of gene conservation. Notably, the two symbiont clades possess putative functional differences in sulfide physiology, anaerobic respiration and dependency on environmental vitamin B12, which probably reflect adaptations to different ecological habitats available to each symbiont group. Overall, these results contribute to our understanding of the eco-evolutionary processes shaping reductive genome evolution in vertically transmitted symbioses.

description: Coral bleaching is the single largest global threat to coral reefs worldwide. Integrating the diverse body of work on coral bleaching is critical to understanding and combating this global problem. Yet investigating the drivers, patterns, and processes of coral bleaching poses a major challenge. A recent review of published experiments revealed a wide range of experimental variables used across studies. Such a wide range of approaches enhances discovery, but without full transparency in the experimental and analytical methods used, can also make comparisons among studies challenging. To increase comparability but not stifle innovation, we propose a common framework for coral bleaching experiments that includes consideration of coral provenance, experimental conditions, and husbandry. For example, reporting the number of genets used, collection site conditions, the experimental temperature offset(s) from the maximum monthly mean (MMM) of the collection site, experimental light conditions, flow, and the feeding regime will greatly facilitate comparability across studies. Similarly, quantifying common response variables of endosymbiont (Symbiodiniaceae) and holobiont phenotypes (i.e., color, chlorophyll, endosymbiont cell density, mortality, and skeletal growth) could further facilitate cross-study comparisons. While no single bleaching experiment can provide the data necessary to determine global coral responses of all corals to current and future ocean warming, linking studies through a common framework as outlined here, would help increase comparability among experiments, facilitate synthetic insights into the causes and underlying mechanisms of coral bleaching, and reveal unique bleaching responses among genets, species, and regions. Such a collaborative framework that fosters transparency in methods used would strengthen comparisons among studies that can help inform coral reef management and facilitate conservation strategies to mitigate coral bleaching worldwide.

description: Domestic cats play pivotal roles in transmitting Toxoplasma gondii: This parasite reproduces sexually only in felid intestines, after which its oocysts are shed in feces for several weeks. Though acute infection in fetal or immunocompromised cats can be lethal, from 18-80% of domestic cats are T. gondii-seropositive and have a chronic, naturally occurring, asymptomatic infection. Though chronic infection affects risk-averse and locomotory behavior in many infected animals, its effect on cat behavior is unknown. We propose that chronic T. gondii infection in domestic cats similarly alters their behavior, specifically to increase its own spread. This idea is based on models of fecally-transmitted disease in areas where resources are shared: if T. gondii mediates the size and characteristics of a cat’s home range, then it will direct where soil is contaminated with fecally-shed T. gondii, which will in turn influence parasite exposure for intermediate hosts as well in cats with overlapping home ranges. We hypothesize that chronic T. gondii infection in domestic cats decreases their risk-averse behavior and leads to increased locomotor activity and exploration. To pilot-test this, we have developed a non-invasive paradigm to evaluate behavioral changes caused by latent T. gondii infection. We used a controlled environment to test whether T. gondii-infected cats exhibit altered risk-aversion behavior. Because natural ecosystems include a suite of species that vary in their roles as hosts for T. gondii, this study provides a foundational understanding of whether the nature of the host (obligate versus intermediate) affects how T. gondii manipulates host behavior. We recruited owners of pet cats, then cross-sectionally evaluated whether risk-aversion and locomotory activity in their cats differ by seropositive status. In one behavioral paradigm, cat behavior is recorded over a series of episodes with and without the owner. When the owner is present, s/he sits and interacts with their cat. After an initial set of familiarization episodes, a balanced scent-based paradigm is used to evaluate a risk-averse response. We demonstrate that this least-invasive paradigm is useful to infer behavioral changes that may result from alteration of dopamine tone via T. gondii infection. This work contribute to a theoretical framework to understand how the risk of infection by fecal-transmitted parasites is influenced by patterns of cat behavior and inform guidelines for controlling this parasite’s spread.

description: We report on our studies of fractal butterflies in biased bilayer graphene in the fractional quantum Hall effect (FQHE) regime. We have considered the case when the external periodic potential is present in one layer and have illustrated the effect of varying both the periodic potential strength and the bias voltage on the FQHE and the butterfly energy gaps. Interestingly, the butterfly spectra exhibits remarkable phase transitions between the FQHE gap and the butterfly gap for chiral electrons in bilayer graphene, by varying either the periodic potential strength or the bias voltage. We also find that, in addition to those phase transitions, by varying the bias voltage one can essentially control the periodic potential strength experienced by the electrons.

description: One fact that stands out very clearly in the discussion of these villages is that most of the deities that were originally venerated in these villages, as in other villages in Salcete - or the rest of Goa for that matter - seem to be clearly pre-Brāmhaṇical. Bētāḷ, Sānter and Purūṣ are definitely not a part of the pantheon brought in by the brāhmaṇ from Central Asia. In Valdiya’s words, quoting from Matsya Puranam (Ch. 114) ‘the dēv and dēvatā lived in the beautiful landscape straddling across Uzbekistān, Tājikistān and Kyrgyzstān’. [Valdiya, 2012 : Geography, Peoples and Geodynamics of India in Purāṇas and Epics, 107] The men of this ethnic group were ‘tall with splendid physique, fair skin with pinkish hue on faces, and the women were very pretty, with pink cheeks, lotus like eyes and blonde hair’. [Valdiya, 2012 : 105] Valdiya is describing the brāmhaṇ who migrated into the Indian peninsula around 2,000 BCE in search of greener pastures for themselves and their animals. They brought along their ‘gods’ (who were their kings or heroes) and their oral ‘scriptures’ (which was their lived history till then). It is these Gods and scriptures that we have called ‘brāmhaṇical’; that is the sense in which we have used the term ‘pre-Brāmhaṇical’.

description: Automatic image-based severity estimation is an important task in computer-aided diagnosis. Severity estimation by deep learning requires a large amount of training data to achieve a high performance. In general, severity estimation uses training data annotated with discrete (i.e., quantized) severity labels. Annotating discrete labels is often difficult in images with ambiguous severity, and the annotation cost is high. In contrast, relative annotation, in which the severity between a pair of images is compared, can avoid quantizing severity and thus makes it easier. We can estimate relative disease severity using a learning-to-rank framework with relative annotations, but relative annotation has the problem of the enormous number of pairs that can be annotated. Therefore, the selection of appropriate pairs is essential for relative annotation. In this paper, we propose a deep Bayesian active learning-to-rank that automatically selects appropriate pairs for relative annotation. Our method preferentially annotates unlabeled pairs with high learning efficiency from the model uncertainty of the samples. We prove the theoretical basis for adapting Bayesian neural networks to pairwise learning-to-rank and demonstrate the efficiency of our method through experiments on endoscopic images of ulcerative colitis on both private and public datasets. We also show that our method achieves a high performance under conditions of significant class imbalance because it automatically selects samples from the minority classes.

description: The purpose of this paper is to report on new parents' experiences of using the available range of parenting resources that help to guide parenting choices and practices. Using a semi-structured interview schedule, 30 participants were asked about their engagement with parenting resources. The types of resources considered most salient to the participants of this study in Victoria, Australia, included professional services, peers, family and friends, and written material. On the whole, these parents valued expert opinion when they encountered problems but experienced a level of frustration when they did not 'feel heard' by professionals or when faced with mixed messages. While they reported some resistance to overt advice offered by family and friends, especially if the information was considered 'out-dated', they relied heavily on informal advice and support from peers, even if this was supported only by anecdotal evidence.

description: Coral reefs are important ecosystems that are increasingly negatively impacted by human activities. Understanding which anthropogenic stressors play the most significant role in their decline is vital for the accurate prediction of future trends in coral reef health and for effective mitigation of these threats. Here we present annually resolved boron and carbon isotope measurements of two cores capturing the past 90 years of growth of the tropical reef-building coral Siderastrea siderea from the Belize Mesoamerican Barrier Reef System. The pairing of these two isotope systems allows us to parse the reconstructed pH change into relative changes in net ecosystem productivity and net ecosystem calcification between the two locations. This approach reveals that the relationship between seawater pH and coral calcification, at both a colony and ecosystem level, is complex and cannot simply be modeled as linear or even positive. This study also underscores both the utility of coupled δ11B-δ13C measurements in tracing past biogeochemical cycling in coral reefs and the complexity of this cycling relative to the open ocean.

description: The circular velocity function (CVF) of galaxies is a fundamental test of the $Λ$ Cold Dark Matter (CDM) paradigm as it traces the variation of galaxy number densities with circular velocity ($v_{\rm{circ}}$), a proxy for dynamical mass. Previous observational studies of the CVF have either been based on \ion{H}{I}-rich galaxies, or encompassed low-number statistics and probed narrow ranges in $v_{\rm{circ}}$. We present a benchmark computation of the CVF between $100-350\ \rm{km\ s^{-1}}$ using a sample of 3527 nearby-Universe galaxies, representative for stellar masses between $10^{9.2}-10^{11.9} \rm{M_{\odot}}$. We find significantly larger number densities above 150 $\rm{km\ s^{-1}}$ compared to results from \ion{H}{I} surveys, pertaining to the morphological diversity of our sample. Leveraging the fact that circular velocities are tracing the gravitational potential of halos, we compute the halo mass function (HMF), covering $\sim$1 dex of previously unprobed halo masses ($10^{11.7}-10^{12.7} \rm{M_{\odot}}$). The HMF for our sample, representative of the galaxy population with $M_{200}\geqslant10^{11.35} \rm{M_{\odot}}$, shows that spiral morphologies contribute 67 per cent of the matter density in the nearby Universe, while early types account for the rest. We combine our HMF data with literature measurements based on \ion{H}{I} kinematics and group/cluster velocity dispersions. We constrain the functional form of the HMF between $10^{10.5}-10^{15.5} \rm{M_{\odot}}$, finding a good agreement with $Λ$CDM predictions. The halo mass range probed encompasses 72$\substack{+5 \\ -6}$ per cent ($Ω_{\rm{M,10.5-15.5}} = 0.227 \pm 0.018$) of the matter density in the nearby Universe; 31$\substack{+5 \\ -6}$ per cent is accounted for by halos below $10^{12.7}\rm{M_{\odot}}$ occupied by a single galaxy.

description: The study examined Nigerian Government Commitment to R2P principle in relation to military actions in the South East, focusing on Egwu Eke and Operation Udoka. The Nigerian military has conducted various operations in the South East region of the country to combat pro-separatist groups such as the Indigenous People of Biafra (IPOB) and the Eastern Security Network (ESN). These operations, including "Operation Python Dance" (Egwu Eke) and "Operation Udoka," have resulted in a significant number of casualties and collateral damage on both sides. There have been allegations that the military operations aim to target prominent supporters of the Biafran struggle. Human rights groups have reported killings and torture of unarmed individuals during these operations. The International Criminal Court (ICC) has initiated an investigation into the September 2017 invasion of a community in Abia State by Nigerian soldiers. The Nigerian government claims that the military operations are necessary to address rising criminal attacks in the region. The study explores the applicability of the United Nations Responsibility to Protect (R2P) principle to protect self-determination proponents in the South East. It suggests that if the Nigerian government fails in its responsibility to protect its citizens, similar to the case of the Rwandan genocide, the United Nations should invoke the R2P doctrine. The study recommends negotiation and/or a referendum as better approaches to address the Biafra agitation rather than a solely kinetic approach by the Nigerian government.

description: Numerous studies have emphasized the significance of various factors such as physical activity, sleep patterns, emotion regulation, socioeconomic status, and feelings of loneliness in predicting mental health indicators. However, a comprehensive investigation considering these factors collectively within a unified model has been lacking in previous research. This research aimed to explore the relationships between the biopsychosocial factors during the COVID-19 pandemic. The study evaluated the diverse mental health regulation strategies in the participating countries. The current study sheds light on the potential impact of lockdowns on individuals’ mental health, providing essential guidance for tailored interventions aimed at improving overall mental health and wellbeing.

description: Dietary supplementation of α-lipoic acid, an 8-carbon organosulfur compound, has been widely reported to lower blood glucose concentration and/or improve insulin sensitivity in previous randomized controlled trials. Although animal model studies further report fairly consistent lipid lowering in both blood and tissue pools in response to α-lipoic acid supplementation, results from human studies are mixed. According to PRISMA guidelines, we conducted a systematic review of published randomized controlled studies (RCTs) to assess the efficacy of α-lipoic acid supplementation as a strategy to improve dyslipidemia, with a focus on serum lipid endpoints including TC, low density lipoprotein cholesterol (LDL-C), HDL-C, and TG. PubMed, EMBASE, Cochrane Evidence-Based Medicine Reviews, Proquest, Web of Science, and Scopus were searched to identify RCTs that reported the effects of α-lipoic acid on blood lipid concentrations from 1970 to 2017. We included RCTs reporting blood lipid responses in adults supplemented with oral α-lipoic acid versus a placebo or control for at least one month. Studies were reviewed and data were extracted by two independent study authors. Seventeen studies were deemed eligible for inclusion. Overall, mean percent changes in blood lipid endpoints in response to α-lipoic acid varied considerably between studies for total cholesterol (–10.5 to +13.9), low-density lipoprotein cholesterol (–19.67 to +9.06), high-density lipoprotein cholesterol (–12.5 to +29.20), and triglycerides (–38.57 to +17.0). Results of this systematic review suggest little consistent benefit on serum lipids in response to α-lipoic acid supplementation. Further well-controlled studies designed and powered to detect improvements in blood lipids in hypercholesterolemic individuals are warranted (PROSPERO registration number: CRD42018105933).

description: The goal of this thesis is to present a comprehensive study of the parabolic and hyperbolic Anderson models with constant initial condition, driven by a Gaussian noise which is fractional in space with index H > 1/2 or H < 1/2, and is either white in time, or fractional in time with index H_0 > 1/2. As a preliminary step, we study the linear stochastic heat and wave equations with the same type of noise. In the case H_0 > 1/2 and H < 1/2, we present a new result, regarding the solution of the parabolic Anderson model with general initial condition given by a measure.

description: Many modern wireless networks integrate carrier sense mul-tiple access/collision avoidance (CSMA/CA) with exponential backoff as medium access control (MAC) technique. In order to decrease the MAC overhead and the collision probability, we propose in this paper a new backoff strategy leading to better saturation throughput and access de-lay performance comparing to the classical protocol. We investigate the CSMA/CA with RTS/CTS technique, and we show that our strategy reaches better saturation throughput and access delay especially in dense networks. This proposed strategy distributes users over all the backoff stages to solve the bottleneck problem present in the first backoff stage. Finally, we analyze our strategy and we compare it to the classical one modeled by Markov chain. Analytical and simulation results show the improvment in term of saturation throughput. Cumulative density func-tion (CDF) of the access delay illustrates the important gain obtained by the proposed strategy.

description: Cross-coupling, which relies on the use of transition metals, is among the most utilized chemical means of establishing carbon-carbon or carbon-heteteroatom bonds between appropriately functionalized sp, sp2, or sp3 centres. However, most cross-coupling reactions rely on the use of palladium to synthesize valuable synthetic targets. This is problematic for the chemical industry as palladium is limited in supply and expensive. Chemists have therefore sought to replace palladium with first-row transition metals (e.g., iron, cobalt and nickel) and recent reports on cobalt and nickel catalyzed cross-coupling reactions indicate that these metals can be used in this capacity. Unfortunately, protocols developed (so far) for these metals are unsuitable for the synthesis of targets with base-sensitive functional groups as they involve strongly basic reaction conditions. Research in this thesis aims to develop both cobalt and nickel pre-formed catalysts that will display high catalytic activity in mildly basic reaction conditions. Current methodologies for cobalt and nickel cross-coupling reactions use either phosphine ligands or NHC ligands of moderate steric bulk (IMes or IPr). Recent advancements in the development of Pd-PEPPSI catalysts have demonstrated that both pre-forming the catalyst and using larger NHC ligands (IPent, IPentCl, or IHept) are required for high catalytic activity in weakly basic conditions. Thus, it was hypothesized that the development of pre-formed cobalt and nickel NHC complexes analogous to their Pd counterparts would improve reactivity in Negishi, Suzuki-Miyaura, and Buchwald-Hartwig amination cross-coupling reactions. Co(IPent)Cl2(Pyr), Co(IPentCl)Cl2(Pyr), and Co2IPr2(OAc)4 were prepared, identified by X-ray crystallography, and evaluated in preliminary Negishi cross-coupling reactions. These complexes were found to be ineffective, but Co2IPr2(OAc)4 was found to be effective for Suzuki-Miyaura cross-coupling. A base screen was performed to enable the use of weak bases, however, the reaction only worked by pre-forming the boronate with n-BuLi, rendering the reaction conditions intolerant of base-sensitive functional groups. [Ni(IPr)]2(µ-Cl)2 , Ni(IPr)Cl(allyl), and Ni(IPent)Cl(allyl) complexes were synthesized and evaluated in Buchwald-Hartwig aminations. Several bases were examined for these reactions but only sodium tert-butoxide was found to be effective. The presence of TEMPO and BHT in these transformations proved deleterious suggesting the involvement of radical intermediates. Finally, stoichiometric reactions were performed to isolate intermediates in the catalytic cycle, supporting the formation of nickel(0).

description: We verified the properties of Ti3C2TxMXene through characterization and further examined that Ti3C2TxMXene could improve the physicochemical properties of Matrigel. Second, we found the MXene-Matrigel hydrogel maintained the proliferation of Cochlea-Orgs and significantly promoted their differentiation abilities. Then, organoid hair cells derived from cochlea stem cells in the MXene-Matrigel group displayed better electrophysiological features comparable to the Matrigel group and comparable to native P2 cochlea inner hair cells. Furthermore, we found that MXene-Matrigel can potentiate hair cell differentiation by activating mTOR signaling. Finally, we successfully developed an initial co-culture system for Cochlear-Orgs and modiolus to establish innervation of hair cells.

‘Stepping aside and listening’: The post-study outcomes and narrated experiences of international graduates of Australian social work education
Creators: name: Battaglia, Lana
Publisher: name: Monash University
Year: 2024
Subjects: classificationCode: 440999
subject: Social work not elsewhere classified

description: This thesis examines the post-study experiences of international graduates of Australian social work education. With its two-phased mixed method approach, varied contextual levels of influence are assessed, enabling a more complex understanding of post-study pathways than previously portrayed about international graduates. Findings from this study have important implications for education, practice, and the profession. A need is identified for international social work students to be recognised more readily as emerging social workers. In turn, their improved recruitment in research about early social work practice may better inform graduates’ preparedness and support for a profession which continues to internationalise and diversify.
