description: This study examines Nigerian journalists’ perception of the affordances of recommendation algorithms in news production and distribution on Opera News Hub. The study uses a triangulation of methods involving content analysis, a semi-structured interview, and a focus group discussion (FGD) with content creators, who have been trained in traditional media practices in Lagos, Nigeria. The findings indicate news stories published on the Hub contravene the platform’s publishing guidelines. The Hub’s recommender system is underpinned by “metricisation” of gatekeeping, which affords soft news over hard news. Hence, content creators of hard news compromise their journalistic autonomy and take on a new professional identity in which they engage in a constant struggle to produce sensational content that will attract audience engagement on Opera News Hub. However, there are indications that Opera News Hub may enhance media sustainability and the welfare of journalists in Nigeria.

Studies on the prevalence and nature of triclabendazole resistance in liver fluke populations from cattle in Australia
Creators: name: Elliott, Timothy Peter

Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the School of Agricultural Sciences, Faculty of Science, Technology and Engineering, LaTrobe University, Bundoora.

Triclabendazole (TCBZ) is widely used to control liver fluke (Fasciola hepatica) infections in livestock in Australia which has led to the development of liver fluke resistant to this drug. This Thesis reports several studies investigating fluke prevalence and the nature of TCBZ resistance in cattle in South-Eastern Australia. (i) We identified a high prevalence (81%) and intensity of fluke infection in the Maffra region indicating that fasciolosis is causing economic losses in dairy cattle. TCBZ resistance ([less than]90% reduction in fluke burdens) was detected on 2 dairy properties in Maffra and on 4/7 beef properties in NSW and Victoria. Live flukes were recovered at slaughter following TCBZ treatment of cattle from 3 beef properties, confirming the TCBZ resistance status of F. hepatica. This is the first report of widespread resistance to TCBZ in F. hepatica from cattle in Australia. (ii) The genetic diversity of TCBZ-resistant, TCBZ-susceptible and field fluke populations was evaluated using mitochondrial genes. We identified several common mtDNA haplotypes that were shared amongst the populations and many less frequent haplotypes. This study revealed a high level of diversity in field and drug resistant flukes in South-Eastern Australia. (iii) The mechanism of TCBZ resistance is yet to be discovered. P-glycoproteins (Pgp) are thought to be involved with the transport of TCBZ out of the parasite and an over-expression or increased efficiency in these proteins may be linked to resistance. A single nucleotide polymorphism (SNP) in a Pgp gene has been proposed as a molecular marker to identify TCBZ resistance. We tested this hypothesis using well-characterised isolates via PCR and DNA cloning and rejected the hypothesis that the SNP could be used as molecular marker, at least in Australian populations. These studies have greatly improved our understanding of the nature of TCBZ resistance in F. hepatica in Australia.

description: Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by the quark-meson coupling model. We find that the in-medium pion valence distribution, as well as the in-medium pion valence wave function, are substantially modified at normal nuclear matter density, due to the reduction in the pion decay constant.

description: This paper presents the results of experiments carried out to determine the formability of AA5754 and AA6111 using electromagnetic forming (EMF), and the effect of the tool/sheet interaction on damage evolution and failure. The experiments consisted of forming 1mm sheets into conical dies of 40° and 45° side angle, using a spiral coil. The experiments showed that both alloys could successfully be formed into the 40?? die, with strains above the conventional forming limit diagram (FLD) of both alloys. Forming into the higher 45° cone resulted in failure for both materials. Metallographic analysis indicated that damage is suppressed during the forming process. Micrographs of the necked and fractured areas of the part show evidence that the materials do not fail in pure ductile fracture, but rather in what could be a combination of plastic collapse, ductile fracture and shear band fracture. The failure modes are different for each material; with the AA5754 parts failing by necking and fracture, with significant thinning at the fracture tip. The AA6111 exhibited a saw tooth pattern fractures, a crosshatch pattern of shear bands in the lower half of the part, and tears in the area close to the tip. Both areas showed evidence of shear fracture. This experimental study indicates that there is increased formability for AA5754 and AA6111 when these alloys are formed using EMF. A major factor in this increase in formability is the reduction in damage caused by the tool/sheet interaction.
Quasiparticle decay in a one-dimensional Bose-Fermi mixture

description: In a one-dimensional weakly interacting Bose-Fermi mixture one branch of elementary excitations is well described by the Bogoliubov spectrum. Here we use the microscopic theory to study the decay of such quasiparticle excitations. The main scattering process which leads to their decay is the backscattering of a Bogoliubov quasiparticle off the Fermi sea, where a particle-hole pair is excited. For a low-momentum quasiparticle (phonon) of momentum $q$, we find that the decay rate scales as $q^3$ provided $q$ is smaller than the Fermi momentum $k_F$, while in the opposite case the decay behaves as $q^2$. If the ratio of the masses of fermions and bosons equals to the ratio of the boson-fermion and the boson-boson interaction strengths, the decay rate changes dramatically. It scales as $q^7$ for $qk_F$. For a high momentum Bogoliubov quasiparticle, we find a constant decay rate for $qk_F$. We also find an analytic expression for the decay rate in the crossover region between low and high momenta. The decay rate is a continuous, but nonanalytic function of the momentum at $q=k_F$. In the special case when the parameters of our system correspond to the integrable model, we observe that the decay rate vanishes.

Media practices, displacement and transnationalism: media of and by Karen refugees from Burma

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the School of Humanities and Social Sciences, College of Arts, Social Sciences and Commerce, La Trobe University, Bundoora.

This thesis is about the media of and by Karen refugees fleeing Burma over the past three decades, exploring how the refugee media are developed and sustained, particularly when their producers and potential audiences are constrained by subordinate status both in their home and host countries. I argue for the need to take account of the realm of media production and the relation between media producers and their creative work in order to understand more closely media practices that take place outside of mainstream media systems and also float above nation-state borders. This study shines new light on the intersecting fields of media and migration studies in that the existing literature has not been attentive to the complex and multifaceted nature of media practices and especially, media production processes in the context of forced displacement. This study finds that the displaced Karen use mediated communication as a tool to cope with the challenges of migration and displacement. Media engagement enables the Karen to maintain and consolidate ties with their homeland cultures and politics and with other Karen communities dispersed across the globe. Accordingly, they can resist being assimilated passively into dominant societies and cultures and also can promote the interests of Karen communities in the diaspora. This study further suggests that the commitment, enthusiasm and skills of a number of Karen refugees involved in the production of diverse forms of media play a significant part in the emergence and persistence of the media practices of displaced Karen, which thereby enhance the capability of the Karen to deal with obstacles and constraints incurred by migration and displacement.

A representation polytope is the convex hull of some finite matrix group $G\leq \operatorname{GL}(d,\mathbb{R})$. We show that the group of permutation matrices is essentially the only finite matrix group which yields a representation polytope with the same face lattice as the Birkhoff polytope.

description: We investigate the $γ$-ray and X-ray properties of the flat spectrum radio quasar (FSRQ) \4c50 at redshift $z= 1.517$. The {\it Fermi} Large Area Telescope (LAT) data indicate that this source was in an active state since 2013 July. During the active period, the $γ$-ray flux increased by more than a factor of three and two distinct flares were detected with the variability timescale as short as several hours. The $γ$-ray spectra can be well fitted by a log-parabola. From the fitting, we find a correlation between the peak energy and spectral curvature for the $γ$-ray spectra, which is the first time seen in $γ$-ray emission from a blazar. The {\it Swift} X-ray Telescope (XRT) data show that the source was variable at X-ray energies, but no evidence shows flux or spectral changes related to the $γ$-ray activity. The broad-band X-ray spectrum obtained with {\it Swift} XRT and {\it NuSTAR} is well described by a broken PL model, with an extremely hard spectrum ($Γ_{1} \sim 0.1$) below the break energy, $E_{\rm break} \sim 2.1 {\rm keV}$, and $Γ_{2} \sim 1.5$ above the break energy. The spectral steepening below $\sim 3$ keV is likely due to the low energy cut-off in the energy distribution of the photon-emitting electron population. Both the $γ$-ray and X-ray emission appear harder when brighter. The broad-band spectral energy distribution (SED) is constructed for the source, and we provide a model fit to the SED. Our modeling suggests that the emission region should be outside the broad line region, and the properties of the region indicate a jet with 42\% of the Eddington power during the active state.

Remarks. Eulichas trapezicollis is almost certainly a senior synonym of E. sikkimensis or E. uniformis, which both occur in Darjeeling. Both species are very similar in habitus, and could be reliably distinguished only based on shape of last antennomere or male genitalia. Unfortunately the original description did not mention any of these diagnostic characters, and the type material of E. trapezicollis seems to be lost. Therefore I am not able to establish the formal synonymy. Type specimens should be deposited in MNHN, but I failed to find them there during my visits. However, I still believe, that more searching could reveal them, and therefore do not designate a neotype, but leave the status of E. trapezicollis unresolved.

Becoming ?-thinker: encounters with Bergson, Deleuze, and immanent art. Implications for post qualitative research

Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the School of Education, Faculty of Education, La Trobe University, Bundoora.

This thesis was a recipient of the Nancy Millis Award for theses of exceptional merit.

This thesis considers Deleuze’s quest to think beyond the habituated subject, by dilating thought, the thinker and the milieu in which both arise, to construct an orientation I call becoming ?-thinker. This is an extension of Deleuze’s ?-being, which is a third term outside of the binary of being and not-being that is generative rather than oppositional. In developing this orientation, I turn to Bergson’s theory of duration and method of intuition, to inform my reading of Deleuze’s immanentist ontology, and allow each facet of my argument to encounter artists, writers and performance artists that I describe as immanent, to elucidate and develop my ideas. Becoming ?-thinker is constructed through four themes, which make up each of the four chapters, namely: the problem of thinking, thinking in duration, thinking multiplicities and finally thinking immanence. Each of these themes is designed to pull thinking apart, and is then applied to recent developments in post qualitative research, with particular reference to the ontological turn that deconstructs the primacy of the cogito, and to research practices that experiment with non-representational epistemologies. I also examine the Bergsonian influence on Deleuze’s critique of the traditional image of thought, by demonstrating how Bergson’s conception of difference allows Deleuze to construct a plane of immanence that accounts for difference without falling into the trap of representation. In doing so, I argue that returning to Bergson’s underused method of intuition adds a precision to Deleuzo-Guattarian research practices, by developing methods of thinking within environments of constant flux, where the subject is constructed in situ through immanent encounters. Finally, I examine the recent Bergson-Deleuzean scholarship that destabilises the theory practice binary to consider how the mode of becoming ?-thinker contributes to addressing the challenges of how one might live in these difficult and complex times.

description: We investigate angular momentum acquisition in Milky Way-sized galaxies by comparing five high resolution zoom-in simulations, each implementing identical cosmological initial conditions, but utilizing different hydrodynamic codes: Enzo, Art, Ramses, Arepo, and Gizmo-PSPH. Each code implements a distinct set of feedback and star formation prescriptions. We find that while many galaxy and halo properties vary between the different codes (and feedback prescriptions), there is qualitative agreement on the process of angular momentum acquisition in the galaxy's halo. In all simulations, cold filamentary gas accretion to the halo results in ~4 times more specific angular momentum in cold halo gas ($λ_{cold} \gtrsim 0.1$) than in the dark matter halo. At z>1, this inflow takes the form of inspiraling cold streams that are co-directional in the halo of the galaxy and are fueled, aligned, and kinematically connected to filamentary gas infall along the cosmic web. Due to the qualitative agreement among disparate simulations, we conclude that the buildup of high angular momentum halo gas and the presence of these inspiraling cold streams are robust predictions of Lambda Cold Dark Matter galaxy formation, though the detailed morphology of these streams is significantly less certain. A growing body of observational evidence suggests that this process is borne out in the real universe.

Cellular trafficking disruption in amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, which causes degeneration and death of motor neurons. Currently there is no effective treatment and understanding the cellular and molecular mechanisms of neurodegeneration is essential for designing an effective therapeutic strategy. Several distinct pathological mechanisms are associated with motor neuron death, but the link between these mechanisms remains unclear. ALS begins in a focal region and appears to spread contiguously throughout the motor neurons in the brain, brain stem and spinal cord, and it remains unclear how the spread of pathology is mediated. Another interesting feature of ALS is that motor neurons are specifically targeted by ubiquitously expressed pathogenic proteins. Disruption of intracellular trafficking processes is one mechanism associated with neurodegeneration in ALS, and this may underlie the specific vulnerability of motor neurons, which have large cell bodies and long axons. The overall aim of this thesis was to examine the role of disruption to intracellular trafficking in neurodegeneration in ALS. The thesis firstly presents an already published study, which demonstrates that uptake of extracellular misfolded wildtype or mutant superoxide dismutase 1 (SOD1) disrupts trafficking from the Endoplasmic reticulum (ER) to Golgi apparatus, induces Golgi fragmentation, ER stress and triggers apoptotic cell death in neuronal cells, providing novel insights into pathogenic mechanisms linked to the ER-Golgi compartments and the mechanism of spread of neurodegeneration in ALS. In the second study (currently under peer review), mechanisms of neurodegeneration linked to optineurin were investigated. Optineurin interacts with the molecular motor myosin VI and it was demonstrated here that this interaction is impaired in both sporadic and familial ALS. This leads to inhibition of optineurin-myosin VI mediated cellular trafficking and autophagy, thus describing novel insights into the pathology induced by optineurin in ALS. This thesis also examines a novel protein associated with ALS. Mutations in CCNF, which encodes a E3 ubiquitin ligase; cyclin F were recently described in familial ALS and expression of this mutant in neuronal cells induced ER stress, recruitment to stress granules and apoptosis. Finally this thesis examines the normal cellular function of C9orf72 (chromosome 9 open reading frame 72), which is associated with most cases of familial ALS. Depletion of C9orf72 led to impairment of endocytosis and autophagy, implying that the normal function of C9orf72 is related to cellular trafficking. In conclusion this thesis provides further evidence that disruption of cellular trafficking processes trigger neurodegeneration in ALS.

description: The final evolution of stars in the mass range 70 - 140 solar masses is explored. Depending upon their mass loss history and rotation rates, these stars will end their lives as pulsational pair-instability supernovae producing a great variety of observational transients with total durations ranging from weeks to millennia and luminosities from 10$^{41}$ to over 10$^{44}$ erg s$^{-1}$. No non-rotating model radiates more than $5 \times 10^{50}$ erg of light or has a kinetic energy exceeding $5 \times 10^{51}$ erg, but greater energies are possible, in principle, in magnetar-powered explosions which are explored. Many events resemble Type Ibn, Icn, and IIn supernovae, and some potential observational counterparts are mentioned. Some PPISN can exist in a dormant state for extended periods, producing explosions millennia after their first violent pulse. These dormant supernovae contain bright Wolf-Rayet stars, possibly embedded in bright x-ray and radio sources. The relevance of PPISN to supernova impostors like Eta Carinae, to super-luminous supernovae, and to sources of gravitational radiation is discussed. No black holes between 52 and 133 solar masses are expected from stellar evolution in close binaries.

description: Abstract

White oyster mushrooms are an agricultural product that has a high nutritional content compared to other mushrooms.  White oyster mushrooms have the following nutritional values: 27% protein, 1.6% fat, 58% carbs, 11.5% fiber, 9.3% ash, and 265 calories. One of the commodities that the public is presently requesting in order to satisfy their eating demands is oyster mushrooms. Planting mediums such as sawdust, rice bran, straw, husks, and rice flour are typically utilized to cultivate oyster mushrooms.   Finding out how rice bran, maize bran, wheat bran, and sago flour applied optimally affected the white oyster mushroom mycelium development rate and yield was the main goal of this study. The study was conducted in Jasne Kumbung, Guntung Manggis street No. 47, Guntung Manggis Village, Landasan Ulin District, Banjarbaru City, South Kalimantan, from December 2023 to March 2024. With four treatments and four replications, this study used a single component Randomized Block Design (CRD) to produce 20 experimental units. The utilization of rice bran, corn bran, wheat bran, and sago starch was shown to have an impact on the rate of mycelium development and production levels of white oyster mushrooms. The best treatment for the average growth rate of perfect mycelium is sago flour treatment (P4 ), the average initial appearance of the first mushroom fruiting body and the average number of clumps per baglog is wheat bran treatment (P1 ), mushroom fruit growth and fruit wet weight The best treatment for oyster mushrooms is wheat bran (P3 ).

The Essence of Universal Gravitation and the Power of the Expansion of the Universe

description: Newton discovered the law of universal gravitation, but did not explain the essence of gravitation. The explanation of gravity in the general theory of relativity is not perfect and the theory does not explain the meaning of the gravitational constant G. The phenomenon of cosmic expansion conflicts with the theory of universal gravitation. Therefore, scientists introduce the concept of dark energy, but there is no clear answer to what dark energy is. Based on the scientific achievements of The Big Bang Theory, quark model and Parton model, this paper puts forward the theory of fluid gravity, deduces a new gravity formula, and reveals the essence of universal gravity and the power of cosmic expansion. It is concluded that the gravity constant G is a changing quantity, the gravity of celestial bodies is limited and may not form a real black hole. The theory predicts that gravity can be partially shielded.

In the Australian context, failure to learn to read is often viewed as the result of something being wrong with the person, or the result of something being wrong with the environment (teaching) or an interaction of both (Benton, 1980; Gallagher, 2006). This belief impacts Australian teachers who in the main, have not been provided the additional training and support required to identify and accommodate specific learning disabilities in the classroom. It also impacts students with specific learning disabilities who are often unsupported within an environment that does not understand their learning differences. Inconsistent definitions of disability across states and education sectors in Australia have also resulted in differences between school funding policies and access to quality education for students with specific learning disabilities (Australian Federation of Disability Organisations, 2013). This is not the case within the Australian tertiary education sector which has for the past twenty years, stood apart from the compulsory education sector and taken both a proactive and responsible approach to the issue of recognising and supporting students with specific learning disabilities in an educational context. This research explored strategies that facilitate success for students with a specific learning disability in tertiary education. Ten tertiary education providers across Victoria participated in this study. Disability practitioners who support students with specific learning disabilities on a day to day basis shared their practice knowledge through both focus group and individual in-depth interviews. Through this process a framework for evidence based good practice emerged. It is proposed that the framework, based on a personalized learning approach is both empowering and sustainable for individuals across their lifespan and is a model of practice that can be implemented across all sectors of education in Australia.

description: In this work we calculate the mass spectrum of charmonium for $1P,...,3P$ states of $0^{++}$ , $1^{++}$, as well as for $1S,...,4S$ states of $0^{-+}$, and $1S, ...,5D$ states of $1^{--}$ along with the two-photon decay widths of ground and first excited state of $0^{++}$ quarkonia for the process, $O^{++}\rightarrow γγ$ in the framework of a QCD motivated Bethe-Salpeter Equation. In this $4\times 4$ BSE framework, the coupled Salpeter equations are first shown to decouple for the confining part of interaction, under heavy-quark approximation, and analyically solved, and later the one-gluon-exchange interaction is perturbatively incorporated leading to mass spectral equations for various quarkonia. The analytic forms of wave functions obtained are used for calculation of two-photon decay widths of $χ_{c0}$. Our results are in reasonable agreement with data (where ever available) and other models.

description: This thesis expands the meaning of the term “trans*,” which is usually used to describe categories of gender, to consider how this term might be redefined through poetry and used to critique the ways in which broader categories of “body” “personhood” and “animacy” are socially recognised and organised. It is comprised of Part I, Hydro, Electric, Dam., a book-length sequence of poetry exploring trans* experience, family life, history, geography and climate, and Part II, a critical study of trans* poetry and poetics.

description: We develop a method to construct a microscopic optical potential from chiral interactions for nucleon-nucleus scattering. The optical potential is constructed by combining the Green's function approach with the coupled-cluster method. To deal with the poles of the Green's function along the real energy axis we employ a Berggren basis in the complex energy plane combined with the Lanczos method. Using this approach, we perform a proof-of-principle calculation of the optical potential for the elastic neutron scattering on $^{16}{\rm O}$. For the computation of the ground-state of $^{16}{\rm O}$, we use the coupled-cluster method in the singles-and-doubles approximation, while for the $A=\pm 1$ nuclei we use particle-attached/removed equation-of-motion method truncated at two-particle-one-hole and one-particle-two-hole excitations, respectively. We verify the convergence of the optical potential and scattering phase shifts with respect to the model-space size and the number of discretized complex continuum states. We also investigate the absorptive component of the optical potential (which reflects the opening of inelastic channels) by computing its imaginary volume integral and find an almost negligible absorptive component at low-energies. To shed light on this result, we computed excited states of $^{16}{\rm O}$ using equation-of-motion coupled-cluster method with singles-and-doubles excitations and we found no low-lying excited states below 10~MeV. Furthermore, most excited states have a dominant two-particle-two-hole component, making higher-order particle-hole excitations necessary to achieve a precise description of these core-excited states. We conclude that the reduced absorption at low-energies can be attributed to the lack of correlations coming from the low-order cluster truncation in the employed coupled-cluster method.

description: It is known that each of the successive quotient groups of the grope and solvable filtrations of the knot concordance group has an infinite rank subgroup. The generating knots of these subgroups are constructed using iterated doubling operators. In this paper, for each of the successive quotients of the filtrations we give a new infinite rank subgroup which trivially intersects the previously known infinite rank subgroups. Instead of iterated doubling operators, the generating knots of these new subgroups are constructed using the notion of algebraic $n$-solutions, which was introduced by Cochran and Teichner. Moreover, for each slice knot $K$ whose Alexander polynomial has degree greater than 2, we construct the generating knots such that they have the same derived quotients and higher-order Alexander invariants up to a certain order. In the proof, we use an $L^2$-theoretic obstruction for a knot to being $n.5$-solvable given by Cha, which is based on $L^2$-theoretic techniques developed by Cha and Orr. We also generalize the notion of algebraic $n$-solutions to the notion of $R$-algebraic $n$-solutions where $R$ is either rationals or the field of $p$ elements for a prime $p$.
