description: Call to Action 93 requests revision of the Canadian citizenship materials to include more information about treaties and residential schools. Although the citizenship materials have been analyzed in terms of how they present the concepts of citizenship, multiculturalism, and Canadian values, little work has been done on how Discover Canada (2012) presents the history of Indigenous peoples in Canada in relation to the Calls to Action. Discover Canada (2012) includes only one mention of the term “residential schools” and four mentions of the terms “treaty” or “treaties” in relation to Indigenous groups. Equally troubling, though, is the guide’s overall characterization of Indigenous groups and their history in Canada. By asking critical questions about textual features that fit into TESL curricula, I demonstrate how TESL instructors can both meet the language teaching requirements of their institutions and answer Call to Action 93 by presenting alternative narratives about Indigenous history in Canada.

description: In classical Hamiltonian theories, entropy may be understood either as a statistical property of canonical systems, or as a mechanical property, that is, as a monotonic function of the phase space along trajectories. In classical mechanics, there are theorems which have been proposed for proving the non-existence of entropy in the latter sense. We explicate, clarify and extend the proofs of these theorems to some standard matter (scalar and electromagnetic) field theories in curved spacetime, and then we show why these proofs fail in general relativity; due to properties of the gravitational Hamiltonian and phase space measures, the second law of thermodynamics holds. As a concrete application, we focus on the consequences of these results for the gravitational two-body problem, and in particular, we prove the non-compactness of the phase space of perturbed Schwarzschild-Droste spacetimes. We thus identify the lack of recurring orbits in phase space as a distinct sign of dissipation and hence entropy production.

description: Olive mill wastewater (OMW) management is an economic and environmental challenge for olive oil-producing countries. The recovery of components with high added value, such as antioxidants, is a highly researched approach that could help refinance performant wastewater treatment systems. Anaerobic (co-)digestion is a suitable process to valorize the energetic and nutritional content of OMW and OMW-derived waste streams from resource recovery processes. Issues of process stability, operation, and yields discourage industrial application. Deepening the understanding of biomethane potential, continuous anaerobic digester operational parameters, and co-substrates is key to large-scale implementation. The biomethane potential of different OMW-derived samples and organic solid market waste as co-substrate was 106–350 NL methane per kg volatile solids (VS). The highest yields were obtained with the co-substrate and depolyphenolized OMW mixed with retentate from an ultrafiltration pretreatment. Over 150 days, an anaerobic fixed-bed 300 L digester was operated with different OMW-derived substrates, including OMW with selectively reduced polyphenol concentrations. Different combinations of organic loading rate and hydraulic retention time were set. The biogas yields ranged from 0.97 to 0.99 L of biogas per g of volatile solids (VS) eliminated, with an average methane content in the produced biogas of 64%. Potential inhibition of the process due to high polyphenol concentrations or over-acidification through volatile fatty acids was avoided in the continuous process through process and substrate manipulation. High concentrations of potassium and low concentrations of nitrogen and phosphate end up in the digestate. Sulfate reduction results in high H2S concentrations in the biogas. The digestate was tested for phytotoxic properties via the germination index. Diluted digestate samples improved germination by up to 50%.

description: Employing the high-resolution observations from the Solar Dynamics Observatory (SDO) and the Interface Region Imaging Spectrograph (IRIS), we statistically investigate flux rope proxies in NOAA AR 11897 from 14-Nov-2013 to 19-Nov-2013 and display two fan-spine structures in this AR. For the first time, we detect flux rope proxies of NOAA 11897 for total 30 times in 4 different locations. These flux rope proxies were either tracked in both lower and higher temperature wavelengths or only detected in hot channels. Specially, none of these flux rope proxies was observed to erupt, but just faded away gradually. In addition to these flux rope proxies, we firstly detect a secondary fan-spine structure. It was covered by dome-shaped magnetic fields which belong to a larger fan-spine topology. These new observations imply that considerable amounts of flux ropes can exist in an AR and the complexity of AR magnetic configuration is far beyond our imagination.

description: Extensions of the photon and graviton soft theorems are derived in 4d local effective field theories with massless particles of arbitrary spin. We prove that effective operators can result in new terms in the soft theorems at subleading order for photons and subsubleading order for gravitons. The new soft terms are unique and we provide a complete classification of all local operators responsible for such modifications. We show that no local operators can modify the subleading soft graviton theorem. The soft limits are taken in a manifestly on-locus manner using a complex double deformation of the external momenta. In addition to the new soft theorems, the resulting master formula yields consistency conditions such as the conservation of electric charge, the Einstein equivalence principle, supergravity Ward identities, and the Weinberg-Witten theorem.

Is There Room For the Other in a “Modernized” Education?

Year: 2023

description: The enactment of the Education Modernization Act by the government of Manitoba in early 2021 proposed several structural changes to the governance and delivery of provincial education. The related documents had a strong emphasis on improving the achievement of all students, making them future-ready and strengthening parental involvement. Despite potentially relevant claims of equity and diversity promotion, in this paper we discuss how the government discourse is neither modern nor necessarily better, as it claims to be. Rather, the proposed Education Modernization Act reifies mainstream worldviews and ideas that have been proclaimed since the beginning of the 20th century and which are today empowered by a global neoliberal mindset. We conclude arguing that a non-totalizing response to the Other is a necessary and yet missing disposition in any genuine social justice education.

Creators: name: Yalembrhan, Debebe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The release of wastewater with heavy metals of Cu, Pb, Zn, Cd etc. Particularly in areas with expansion of industries can pose a significant threat to human health and environment due to their toxicity. This paper deals with bio sorption of heavy metals (copper and lead) using acid treated dried lemna minor powder. The adsorbent after treated with hydrochloric acid was dried and ground to a particle size range of (820-850) µm. Characterization of the adsorbent such as proximate analysis, surface charge, FTIR spectroscopy, surface area and XRD was done prior to bio sorption process. A batch adsorption experiment was carried out using central composite design expert 6.0.8 and the effect of adsorption parameters: pH, initial metal concentration, and adsorbent dose was studied. The result indicated that maximum percentage removal of 92.45 % for Lead (II) was obtained at pH = 11. Similarly, 88.4 % removal was found for Copper (II) at pH = 9. Temperature effects showed that the adsorption process was endothermic with positive enthalpy and negative free Gibbs energy values. The Removal efficiency of lemna minor increased with increase in temperature. Data's from the adsorption were analyzed with Temkin, Langmuir and Freundlich isotherm models. Desorption of Cu +2 and Pb +2 were carried out by using a 100ml of 0.1M HCl in to 250 volumetric flasks with 0.1 g of 43.86 ppm of copper and 42.38 ppm of Lead loaded sun dried lemna minor. The percent desorption increased with time for both metals and maximum desorption observed at 60-minute contact time with 80% for Lead and 72.2% for Copper.

description: An $n \times n$ partial Latin square $P$ is called $α$-dense if each row and column has at most $αn$ non-empty cells and each symbol occurs at most $αn$ times in $P$. An $n \times n$ array $A$ where each cell contains a subset of $\{1,\dots, n\}$ is a $(βn, βn, βn)$-array if each symbol occurs at most $βn$ times in each row and column and each cell contains a set of size at most $βn$. Combining the notions of completing partial Latin squares and avoiding arrays, we prove that there are constants $α, β> 0$ such that, for every positive integer $n$, if $P$ is an $α$-dense $n \times n$ partial Latin square, $A$ is an $n \times n$ $(βn, βn, βn)$-array, and no cell of $P$ contains a symbol that appears in the corresponding cell of $A$, then there is a completion of $P$ that avoids $A$; that is, there is a Latin square $L$ that agrees with $P$ on every non-empty cell of $P$, and, for each $i,j$ satisfying $1 \leq i,j \leq n$, the symbol in position $(i,j)$ in $L$ does not appear in the corresponding cell of $A$.

description: We study localized nonlinear waves on a plane wave background in the multiple self-induced transparency (SIT) system, which describes an important enhancement of the amplification and control of optical waves compared to the single SIT system. A hierarchy of exact multiparametric rational solutions in a compact determinant representation are presented. We demonstrate that, this family of solutions contains known rogue wave solution and unusual W-shaped soliton solution, which strictly corresponds to the linear stability analysis that involves modulation instability and stability regimes in the low perturbation frequency region. State transitions between rogue waves and W-shaped solitons as well as the higher-order nonlinear superposition modes are revealed by the suitable choice for the background wavenumber of electric field component. In particular, our results show that, the multiple SIT system admits stationary and nonstationary nonlinear modes in contrast to the results in the single SIT system. Correspondingly, the important characteristics of the nonlinear waves including trajectories and spectrum are revealed in detail.

description: Constructed Technosols are an important means of substituting natural soil material, such as peat and geogenic material, for use in urban green infrastructure. One characteristic of Technosols important to their role in urban green infrastructure, specifically with respect to urban water management, is their soil hydraulic properties (SHPs). The SHPs depend on the composition of the constructed Technosols (e.g. their components and their mixing ratio). The diversity of possible components and the infinite number of mixing ratios practically prohibit the experimental identification of the composition needed to achieve suitable soil hydrological functions. In this study, we propose a compositional model for predicting the water retention curves (WRCs) of any binary mixture based on the measured WRCs of its two pure components only (basic scheme) or with one additional mixture (extended scheme). The unsaturated hydraulic conductivity curves (HCCs) are predicted based on the modelled WRCs. The compositional model is developed from existing methods for estimating the porosity of binary mixtures. The model was tested on four data sets of measured WRCs of different binary mixtures. The distribution of water and air in 50 cm high soil columns filled with these mixtures was predicted under hydrostatic conditions in order to assess their suitability for typical urban applications. The difference between the maxima of the pore size distributions ΔPSDmax (m) of the components indicates the applicability of the compositional approach. For binary mixtures with small ΔPSDmax, the water content deviations between the predicted and the measured WRCs range from 0.004 to 0.039 cm3 cm−3. For mixtures with a large ΔPSDmax, the compositional model is not applicable. The prediction of the soil hydraulic properties of any mixing ratio facilitates the simulation of flow and transport processes in constructed Technosols before they are produced (e.g. for specific urban water management purposes).

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Composting of sugar cane filter cake can improve soil quality and productivity as well as sustainability of agricultural production by replenishing soil organic matter and supplying nutrients. In Metehara Sugar Factory, filter cake and vinasse generation is estimated to be 33,600 tons/year and 500 m 3 /day respectively. Thus, composting of byproducts generated in the factory is essential to reduce the environmental impact due to disposal of the waste to water bodies. In this research paper, windows composting of filter cake and vinasse has been investigated at Metehara Sugar Factory for about 8 weeks of composting period. During this process, the degradable organic substrate undergoes chemical and physical transformation to give a stable and humidified end product. The present study deals with the sources, composting and strategies for future management of filter cake. The study also, includes the quantification, characterization and economic analysis of the compost from Metehara Sugar Factory. In the experiment, the physical and chemical characteristics has been analyzed at Metehara and Wonji research center. According to the laboratory results, fresh filter cake contains 20% organic carbon and 0.8, 0.86 and 1.1 % NPK respectively. Similarly, the matured compost has 17.8% organic carbon and 1.4 %, 0.63 % and 1.27 % NPK respectively. Thus, the product is of value in agriculture both as an organic fertilizer and soil improver. The economic analysis of composting shown that recycling the nutrient yield can substitute 0.2 % of DAP consumed or saves 322,560 USD/year.

description: Generative Adversarial Networks (GANs) have consistently defined the state-of-the-art in the generative modelling of high-quality images in several applications. The images generated using GANs, however, do not lend themselves to being directly used in supervised learning tasks without first being curated through annotations. This dissertation investigates how to carry out automatic on-the-fly segmentation of GAN-generated images and how this can be applied to the problem of producing high-quality simulated data for X-ray based security screening. The research exploits the hidden layer properties of GAN models in a self-supervised learning framework for the automatic one-shot segmentation of images created by a style-based GAN. The framework consists of a novel contrastive learner that is based on a Sinkhorn distance-based clustering algorithm and that learns a compact feature space for per-pixel classification of the GAN-generated images. This facilitates faster learning of the feature vectors for one-shot segmentation and allows on-the-fly automatic annotation of the GAN images. We have tested our framework on a number of standard benchmarks (CelebA, PASCAL, LSUN) to yield a segmentation performance that not only exceeds the semi-supervised baselines by an average wIoU margin of 1.02 % but also improves the inference speeds by a factor of 4.5. This dissertation also presents BagGAN, an extension of our framework to the problem domain of X-ray based baggage screening. BagGAN produces annotated synthetic baggage X-ray scans to train machine-learning algorithms for the detection of prohibited items during security screening. We have compared the images generated by BagGAN with those created by deterministic ray-tracing models for X-ray simulation and have observed that our GAN-based baggage simulator yields a significantly improved performance in terms of image fidelity and diversity. The BagGAN framework is also tested on the PIDRay and other baggage screening benchmarks to produce segmentation results comparable to their respective baseline segmenters based on manual annotations.

description: The eikonal equation is instrumental in many applications in several fields ranging from computer vision to geoscience. This equation can be efficiently solved using the iterative Fast Sweeping (FS) methods and the direct Fast Marching (FM) methods. However, when used for a point source, the original eikonal equation is known to yield inaccurate numerical solutions, because of a singularity at the source. In this case, the factored eikonal equation is often preferred, and is known to yield a more accurate numerical solution. One application that requires the solution of the eikonal equation for point sources is travel time tomography. This inverse problem may be formulated using the eikonal equation as a forward problem. While this problem has been solved using FS in the past, the more recent choice for applying it involves FM methods because of the efficiency in which sensitivities can be obtained using them. However, while several FS methods are available for solving the factored equation, the FM method is available only for the original eikonal equation. In this paper we develop a Fast Marching algorithm for the factored eikonal equation, using both first and second order finite-difference schemes. Our algorithm follows the same lines as the original FM algorithm and requires the same computational effort. In addition, we show how to obtain sensitivities using this FM method and apply travel time tomography, formulated as an inverse factored eikonal equation. Numerical results in two and three dimensions show that our algorithm solves the factored eikonal equation efficiently, and demonstrate the achieved accuracy for computing the travel time. We also demonstrate a recovery of a 2D and 3D heterogeneous medium by travel time tomography using the eikonal equation for forward modelling and inversion by Gauss-Newton.

description: Aims. We aim to probe the internal structure and investigate more detailed information of the $δ$ Scuti star HD 50844 with asteroseismology. Methods. We analyse the observed frequencies of the $δ$ Scuti star HD 50844 obtained by Balona (2014), and search for possible multiplets based on the rotational splitting law of g-mode. We tried to disentangle the frequency spectra of HD 50844 by means of the rotational splitting only. We then compare them with theoretical pulsation modes, which correspond to stellar evolutionary models with various sets of initial metallicity and stellar mass, to find the best-fitting model. Results. There are three multiplets including two complete triplets and one incomplete quintuplet, in which mode identifications for spherical harmonic degree $l$ and azimuthal number $m$ are unique. The corresponding rotational period of HD 50844 is found to be 2.44$^{+0.13}_{-0.08}$ days. The physical parameters of HD 50844 are well limited in a small region by three modes identified as nonradial ones ($f_{11}$, $f_{22}$, and $f_{29}$) and by the fundamental radial mode ($f_{4}$). Our results show that the three nonradial modes ($f_{11}$, $f_{22}$, and $f_{29}$) are all mixed modes, which mainly represent the property of the helium core. The fundamental radial mode ($f_{4}$) mainly represents the property of the stellar envelope. In order to fit these four pulsation modes, both the helium core and the stellar envelope must be matched to the actual structure of HD 50844. Finally, the mass of the helium core of HD 50844 is estimated to be 0.173 $\pm$ 0.004 $M_{\odot}$ for the first time. The physical parameters of HD 50844 are determined to be $M=$ 1.81 $\pm$ 0.01 $M_{\odot}$, $Z=$ 0.008 $\pm$ 0.001. $T_{\rm eff}=$ 7508 $\pm$ 125 K, log$g=$ 3.658 $\pm$ 0.004, $R=$ 3.300 $\pm$ 0.023 $R_{\odot}$, $L=$ 30.98 $\pm$ 2.39 $L_{\odot}$.

Second Chance and the Human Right to Learn
Creators: name: Utheim, Ragnhild
Publisher: name: Critical Education
Year: 2023

description: This article substantiates the need for consolidated government support and coordination of postsecondary correctional education in the United States. The author uses the case of New York as a point of entry to critically examine the human right to learn and transform with dignity – for the millions of people languishing in prisons under mass incarceration— situating the history of higher education in prison within a dynamic network of education providers that emerged across the state. The analysis contends that withholding the right to learn violates a basic human right to (inter)personal growth, and that freedom to learn is fundamentally debased when education embedded in meaningful human relations –absent exploitation, indoctrination or predatory practices— is foreclosed. As such, the threat of fully online modalities and delimited education content comprise a form of censorship that undermines the true value of embodied and diverse learning experiences, with particular ramifications for people in prison.

description: We study the holographic dual description of a superconductor in which the gravity sector consists of a Maxwell field and a charged scalar field which except its minimal coupling to gravity it is also coupled kinematically to Einstein tensor. As the strength of the new coupling is increased, the critical temperature below which the scalar field condenses is lowering, the condensation gap decreases faster than the temperature, the width of the condensation gap is not proportional to the size of the condensate and at low temperatures the condensation gap tends to zero for the strong coupling. These effects which are the result of the presence of the coupling of the scalar field to the Einstein tensor in the gravity bulk, provide a dual description of impurities concentration in a superconducting state on the boundary.

description: Cement manufacturing is a high energy consuming and heavy polluting process. To reduce the energy and environmental costs cement producers are currently using a blend of alternative fuels with conventional fossil fuels. The research was conducted to investigate the potential of Prosopis juliflora charcoal as energy mix in cement industries. Proximate analysis and calorific value of Prosopis juliflora wood and laboratory scale carbonized Prosopis juliflora were done by standard procedure and compared with traditionally produced Prosopis juliflora charcoal. The results showed that ash chemistry for Prosopis juliflora wood and laboratory scale carbonized Prosopis juliflora were performed in order to determine the amount of different oxides present such as SiO2, Fe2O3, Al2O3, CaO & MgO and sulfur were 4.14%, 1.21%, 0.79%, 43.64%, 6.27%, 0.18% and 4.43%, 2.41%, 0.93%, 43.39%, 7.31% & 0.11% respectively. The pyrolysis process of Prosopis juliflora was investigated using a thermogravimetric analyzer. Thermo-chemical decomposition behavior of Prosopis juliflora was carried out over a temperature range of 25 -700°C at the heating rate of 20°C /min under nitrogen. Two response variables; charcoal yield and calorific values were analyzed by varying carbonization temperature (350, 450, 550 and 600°C) and holding time (60, 120, 180, 240 minutes). The maximum charcoal yield was found to be 75.83% at 350°C and 60 minutes of holding time while the minimum charcoal yield was 31.13% at 600°C for 240 minutes of carbonization time. On the other hand, the maximum calorific value 6620 kcal/kg was obtained at 600°C and 240 minutes of holding time and the minimum calorific value was 4196 kcal/kg at 350°C and 60 minutes. All experimental data were analyzed and modeled using Design-Expert version 6.0.8 software and significance was accepted at 0.05 level of probability (p<0.05

description: The three-dimensional Schrödinger equation with a position-dependent (effective) mass is studied in the framework of Supersymmetrical (SUSY) Quantum Mechanics. The general solution of SUSY intertwining relations with first order supercharges is obtained without any preliminary constraints. Several forms of coefficient functions of the supercharges are investigated and analytical expressions for the mass function and partner potentials are found. As usual for SUSY Quantum Mechanics with nonsingular superpotentials, the spectra of intertwined Hamiltonians coincide up to zero modes of supercharges, and the corresponding wave functions are connected by intertwining relations. All models are partially integrable by construction: each of them has at least one second order symmetry operator.

description: We show that under certain general conditions, short sums of $\ell$-adic trace functions over finite fields follow a normal distribution asymptotically when the origin varies, generalizing results of Erdős-Davenport, Mak-Zaharescu and Lamzouri. In particular, this applies to exponential sums arising from Fourier transforms such as Kloosterman sums or Birch sums, as we can deduce from the works of Katz. By approximating the moments of traces of random matrices in monodromy groups, a quantitative version can be given as in Lamzouri's article, exhibiting a different phenomenon than the averaging from the central limit theorem.

description: The event, Talking the Walk: Youth, Women, and Unconnected from Rural India, brought together voices of digital change leaders from underserved and underrepresented communities across India. Organised by Digital Empowerment Foundation and the United Nations in India, the forum highlighted grassroots digital transformation efforts and discussed pathways to achieve the Global Digital Compact (GDC). Leaders from various sectors shared insights into inclusive digital empowerment, underscoring the vital roles of women and youth in India’s digital revolution. The Global Digital Compact (GDC) is a proposed international framework announced by the United Nations to advocate for a collective vision for a shared digital future. It establishes principles for global solidarity, digital accountability, emphasising universal connectivity, data protection, digital inclusion, and respect for human rights online. This meeting aligns with the GDC framework by advocating for bottom-up policymaking informed by grassroots communities. It emphasises the need for community-driven digital solutions, ensuring inclusivity and sustainability in policymaking. In support of the GDC, the event hosted an interactive storytelling session where different stakeholders, including the SoochnaPreneurs, CSOs, and the Digital Experts shared their first-hand experiences about their work with the grassroots, particularly focussing on addressing the graded digital inequalities and the digital divide in their communities. Through this platform, the Soochna Preneurs endorsed the principles of the Compact, reflecting their commitment to equitable digital access and empowerment.

description: In this article we report research exploring students’ perceptions of higher education in élite and local universities in England and Cuba. Currently there is no research/scholarship that has focussed on analysing the perceptions and motivations of students: a) comparing across Cuban and England contexts; and the b) focussing on different types of universities within these countries; which means there is an absence of knowledge to inform policy and practice, for example in relation to widening access to universities. To modestly address this research gap, we use qualitative data from students at two universities in Cuba and two in England. Our analysis reveals shared experiences and notable homogeneity about the social contribution aspect of university study among students at the local universities in both countries and the élite university in Cuba. The élite university students in England were primarily focussed on individual development through university study. We show a need for educators to focus on the way that social class and a localised sense of belonging operate, and also the way that it conditions perceptions and choice in HE systems. More widely, there emerges the need for existential reflection on the key objective of HE policy, and its role and function for promoting the relative balance between individual gain and societal development.

description: The Albert was a wooden schooner of 123 tons built at Bridport by John Cox in 1834 for Bamfields of Falmouth. The Albert sailed to Europe, the Mediterranean, the Black sea, Danube, Australia, South Africa, South and North America. The Albert carried pilchards from St Ives to the Mediterranean seasonally. The Albert was lengthened in 1850 and the tonnage increased to 166 tons. The Albert struck Sarn Bwch causeway near Barmouth on January 7th 1858 in a gale beating to windward on a voyage from Liverpool to Montevideo and sank. The crew took to the boats, being rescued by a passing vessel and landed at Portmadoc after hitting the bar. The valuable cargo of the Albert was recovered by divers and returned to Liverpool.
Integrating urban public bus with LRT: Case of Leghar station.

description: In the last two or three decades an outstanding large increase in traffic congestion, air pollution, pressure on the infrastructure and passengers volumes has occurred. Having a well-designed public transport network that works individually without any coordination with the other modes of public transport was found not to be sufficient. In such a situation providing a door to door trip between all pairs of origins and destinations is neither applicable nor cost-effective. On the other hand transfer time is the waiting time penalty encountered by passengers at a transfer stop or terminal while changing between modes of public transport lines. The higher the transfer time the higher the passengers inconvenience and the lower the ridership rates. The lack of properly planned urban transport in Addis Ababa is manifested through the low degree of efficiency of urban mobility that is now observed in almost all of the city's centre, sub-centers and other major traffic corridors. As case study Identifying transport problems and integration challenges of Addis Ababa transport is main concern. . Thus, as part of research methodology, this paper tries to explore integrated LRT transportation with Anbessa city bus. The objective of this research is to develop a scheduling model for operational integration of LRT services and ANBESSA buses in case of leghar station. Generally, the research I am going to carry out will clearly show the synchronized scheduling of Anbessa city bus and the newly built LRT with operational integration considering waiting time for the case of Leghar station.

description: The purpose of this study is to provide the best conditions for finding a practice effect on the EPT. We thus base our study on a practice procedure that produced an effect in the past (i.e., in Fazio et al., 1986), but try to amplify it by providing more practice (35 trials instead of 5). Moreover, for the EPT we are using an up-to-date procedure, with images instead of words as prime, as these were shown to produce larger priming effects (see Herring et al., 2013).

description: The Alice Bannister was a schooner built by John Gough of Bridgewater in Somerset for John Fisher of Barrow in Furness. Alice Bannister became part of the growing fleet of James Fisher and Sons. Alice Bannister sailed between Britain, Ireland and Europe carrying various cargos of materials. The Alice Bannister sank in 1898 after being in collision 10 miles off Bardsey Island, North Wales with the S S Borrowdale with the loss of one life from the Alice Bannister. A Board of Trade enquiry into the collision found the second mate of the Borrowdale at fault.
