Bibliometric Review On Liver And Tumour Segmentation Using Deep Learning, Jayant Jagtap, Aamir Habeeb, Avinash Jha, Shrey Aggarwal, Khushi Gupta

Library Philosophy and Practice (e-journal)

One of the major organs in the body is liver where tumors occur often. Malignant liver tumors pose a serious hazard to human life and health. Manual segmentation of the liver organ and tumor from computed tomography (CT) scans is difficult, time-consuming, and skewed to the clinician's experience, yet it is essential for hepatic surgical planning. However, due to the following considerations, segmenting liver tumors from computed tomography (CT) images is difficult: In CT pictures, the contrast between the liver tumor and healthy tissues is low, and the boundary is indistinct; the picture of the liver tumor is confusing, with …

Identifying Specific Matrix Metalloproteinase-2-Inhibiting Peptides Through Phage Display-Based Subtractive Screening, Ayli̇n Özdemi̇r Bahadir, Bertan Koray Balcioğlu, Müge Serhatli, Şeyma Işik, Berri̇n Erdağ

Turkish Journal of Biology

Gelatinases A and B, which are members of the matrix metalloproteinase (MMP) family, play essential roles in cancer development and metastasis, as they can break down basal membranes. Therefore, the determination and inhibition of gelatinases is essential for cancer treatment. Peptides that can specifically block each gelatinase may, therefore, be useful for cancer treatment. In this study, subtractive panning was carried out using a 12-mer peptide library to identify peptides that block gelatinase A activity (MMP-2), which is a key pharmacological target. Using this method, 17 unique peptide sequences were determined. MMP-2 inhibition by these peptides was evaluated through zymogram …

Sacred Places: The Interaction Between Space, Time And Faith, Mona Helmy

Architectural Engineering

Sacred places are dedicated places and/or places that are tangibly constructed for a religious or holy purpose, or for a certain belief, such as mosques, churches or temples. Furthermore, sacred places could also be intangible places that are religiously or spiritually interpreted within various spaces, such as mountains, rivers or deserts.

This research paper investigates what makes a place sacred, and if a sacred place is relative, or timeless; for example, if a place is considered sacred for all users, or only for a selected group of users. It also explores whether the sensation of the sacredness in places …

Fairness, Voice, Dialogue: Measuring Collective Social Justice In Schools, Craig Howley, Aimee Howley, Marged Dudek, Courtney Gilday

Mid-Western Educational Researcher

The United States is an inequitable society growing more inequitable in recent decades, and schooling is both part mechanism of oppression and part pathway toward social justice. Improving the extent to which schooling actually contributes to equity, however, depends on efforts to cultivate educator practices that advance social justice. Defining these practices and measuring their use among school faculties are necessary parts of the improvement process. Unfortunately, adequate measures of collective social justice practice in schools have not been developed for use with teachers. Based on a conception of social just as a three-part structure, we report progress on developing …

Voice For Change: Model Of Investment Theory In Professional Development For School Administrators, Iwona Lech, James Cohen

Mid-Western Educational Researcher

This paper is a result of an intensive four-day summer academy designed for administrators and auxiliary staff to be introduced to the world of the English Learner (EL). Although over 95 participants participated in this study, we selected one participant as the focal person for this paper. It presents how one school principal changed and developed as a result of participating in the Summer Academy. In particular, using Investment Theory (Darvin & Norton, 2015) as the theoretical lens we discuss three areas where the Summer Academy played a role in how William viewed and approached working with others: 1) the …

Age Differences In Deliberate Ignorance., Ralph Hertwig, Jan K. Woike, Jürgen Schupp

School of Psychology

People sometimes choose to remain ignorant, even when information comes at low marginal costs and promises high utility. To investigate whether older adults enlist deliberate ignorance more than younger adults, potentially as an emotion-regulation tool, we presented a representative sample of 1,910 residents of Germany with 13 scenarios in which knowledge could result in substantial gains or losses. The strongest correlate of deliberate ignorance was indeed age. Openness to experience was negatively correlated with deliberate ignorance; risk preference did not and neuroticism did not consistently predict it. Findings suggest a possible positivity effect in the decision to access new but …

Goldenwind At Semeval-2021 Task 5: Orthrus – An Ensemble Approach To Identify Toxicity, M Palomino, D Grad, J Bedwell

School of Engineering, Computing and Mathematics

Many new developments to detect and mitigate toxicity are currently being evaluated. Weare particularly interested in the correlation between toxicity and the emotions expressed inonline posts. While toxicity may be disguisedby amending the wording of posts, emotionswill not. Therefore, we describe here an ensemble method to identify toxicity and classify the emotions expressed on a corpus ofannotated posts published by Task 5 of SemEval 2021—our analysis shows that the majority of such posts express anger, sadness andfear. Our method to identify toxicity combinesa lexicon-based approach, which on its ownachieves an F1 score of 61.07%, with a supervised learning approach, which …

A Review Of The Uk And British Channel Islands Practical Tidal Stream Energy Resource, Daniel Coles, Athanasios Angeloudis, Deborah Greaves, Gordon Hastie, Matthew Lewis, Lucas Mackie, James Mcnaughton, Jon Miles, Simon Neill, Matthew Piggott, Denise Risch, Beth Scott, Carol Sparling, Tim Stallard, Philipp Thies, Stuart Walker, David White, Richard Willden, Benjamin Williamson

School of Engineering, Computing and Mathematics

This review provides a critical, multi-faceted assessment of the practical contribution tidal stream energy can make to the UK and British Channel Islands future energy mix. Evidence is presented that broadly supports the latest national-scale practical resource estimate, of 34 TWh/year, equivalent to 11% of the UK’s current annual electricity demand. The size of the practical resource depends in part on the economic competitiveness of projects. In the UK, 124 MW of prospective tidal stream capacity is currently eligible to bid for subsidy support (MeyGen 1C, 80 MW; PTEC, 30 MW; and Morlais, 14 MW). It is estimated that the …

An Exploration Of The Relationship Between Aphasia Therapy, Depression And Quality Of Life In Post-Stroke Patients After Rehabilitation At 12 And 26 Weeks After Stroke: A Verse Sub-Study, Alia Rashid Khan

Theses: Doctorates and Masters

Background: Depression is a common consequence of stroke, and people with aphasia (PWA) post-stroke have a higher risk of developing depression compared to stroke survivors without aphasia. However, current stroke interventions featuring aphasia therapy tend to neglect the effect of the treatment on mood. There is also a lack of evidence on the impact of stroke education and counselling on PWA in early stroke recovery. Additionally, the research on post-stroke depression often excludes or insufficiently describes PWA in study populations. The influence of direct aphasia therapy on depression in PWA is undetermined. This sub-study investigated: i) the effect of …

Cost-Effectiveness Of Exercise Medicine For Prostate Cancer, Kim Edmunds

Theses: Doctorates and Masters

Background

Androgen deprivation therapy (ADT) is associated with numerous adverse effects that impact on quality of life and contribute further to the cost burden of prostate cancer (PCa) via treatment and supportive care. Exercise medicine is effective in slowing PCa progression, reversing treatment adverse effects and improving quality of life and survival of patients, however, no economic analyses have been conducted to determine whether exercise is cost-effective in this population.

Objectives

Firstly, to examine the adverse effects of ADT for PCa and the evidence supporting the use of exercise medicine in their management. Secondly, to conduct the first economic evaluations …

An Investigation Into The Efficacy Of Url Content Filtering Systems, Brett Ronald Turner

Theses: Doctorates and Masters

Content filters are used to restrict to restrict minors from accessing to online content deemed inappropriate. While much research and evaluation has been done on the efficiency of content filters, there is little in the way of empirical research as to their efficacy. The accessing of inappropriate material by minors, and the role content filtering systems can play in preventing the accessing of inappropriate material, is largely assumed with little or no evidence. This thesis investigates if a content filter implemented with the stated aim of restricting specific Internet content from high school students achieved the goal of stopping students …

Applications Of Béla Bartók's Techniques Of Pitch Organisation To Jazz Improvisation, Niran Jay Dasika

Theses: Doctorates and Masters

The music of Hungarian composer Béla Bartók (1881-1945) reconciles hauntingly lyrical beauty with harsh, atonal dissonance, appealing to music fans, musicians, and theorists alike for over a century and suggesting a rich resource of inspiration for improvising musicians. The composer Pierre Boulez commented that “Whether it is in a brutal violence animating a sound material in fusion, or in a tranquil gentleness glowing in a halo of grating sounds and colours… Bartók is incomparable and remains unique”. Informed by Bartók theorists Elliott Antokoletz, János Kárpáti, Erno Lendvai, and by Bartók’s own writings, this research identifies four melodic techniques: ‘mistuning’, ‘chromatic …

Digital Representation For Assessment Of Spoken Efl At University Level: A Case Study In Vietnam, Thi Bich Hiep Vu

Theses: Doctorates and Masters

Assessing the speaking performance of students who are studying English as a Foreign Language (EFL) has mainly been conducted with face-to-face speaking tests. While such tests are undoubtedly interactive and authentic, they have been criticised for subjective scoring, as well as lacking an effective test delivery method and recordings for later review.

Technology has increasingly been integrated into speaking tests over the last decade and become known as computer-assisted or computer-based assessment of speaking. Although this method is widely acknowledged to measure certain aspects of language speaking effectively, such as pronunciation and grammar, it has not yet proved to be …

Navigating The Wreck: Writing Women’S Experience Of The Japanese Occupation Of Singapore. Salvaged From The Wreck: A Novel -And- Diving Into The Wreck: A Critical Essay, Dawn Nora Crabb

Theses: Doctorates and Masters

This thesis is in two parts. The first and major part consists of a historical novel followed, in part two, by an essay. The title of this thesis, “Navigating the Wreck”, refers metaphorically to the Fall of Singapore in 1942, the ensuing human tragedy unleashed on the people of Singapore and Malaya, and the literary and historical processes of exploring, interpreting and depicting the past. The Japanese occupation of Singapore has, to date, been described mostly by Western historians and former prisoners of war who have forged a predominant patriarchal narrative. In that narrative—despite the all-encompassing nature of the occupation …

Performer Training Evolutions: Nsp The Firstborn Son Of Smat, Chelsea Crothers

Theses: Doctorates and Masters

This study examined the Nobbs Suzuki Praxis (NSP), a performer training that evolved as an Australian variant of the Japanese Suzuki Method of Actor Training (SMAT). There has been little research on NSP up until now and this study seeks to establish its importance as a training approach that has the potential to be transformative for the performers who practice it. The study utilised a multi-modal approach that included traditional and practice as research methodologies. The origins of NSP in SMAT were traced to identify similarities and differences, and reveal NSP’s inspirations and the reasons for its subsequent divergent evolution. …

Factors Associated With Intimate Partner Homicide In A West Australian Context, William Anthony Thompson

Theses: Doctorates and Masters

Domestic Violence (DV) is prevalent within Australian society with one in four women experiencing some form ofDV (ABS 2017) in their life. The Australian homicide rate is about 250 deaths per year, of which 52% are domestic related (Virueda & Payne 2010). Domestic homicides include Intimate Partner Homicide (IPH), where the victim and offender shared, or formerly shared an intimate relationship (for example married, defacto and ex partners; Bryant & Cussen 2015). This study analysed the factors of West Australian (WA) IPHs from 2012-2017 inclusive. The aim was to identify aetiologies of IPH offending across ethnicity and gender to understand …

Tasteful Piano Performance In Classic-Era Britain, James Huntingford

Theses: Doctorates and Masters

In recent decades, British solo piano repertoire of the Classic era has attracted increasing interest from researchers. A number of scholars have sought to identify the compositional elements that comprise late eighteenth- and early nineteenth-century British piano music. Despite this interest, there has been little research into the conventions of performance with which this repertoire is inextricably associated. Moreover, scant attention has been given to the notions of taste that are so often encountered in contemporaneous music treatises and philosophical writings. This thesis addresses these gaps in the existing literature by examining tasteful piano performance in late eighteenth- and early …
