Enhancing the Australian doctoral experience: Locating culture and identity at the centre
No full textCulture and identity play a significant role in the education of Indigenous and non-Western doctoral students. While a substantial body of literature explores interpersonal communication in doctoral supervision, it remains largely silent about how history impacts on doctoral students' identities and their potential for unique knowledge creation. This book chapter draws upon postcolonial/decolonial theories and life history methodologies in order to more effectively contextualise Indigenous and non-Western doctoral students' identities in Australia. These life histories include those outlined by the Indigenous and Chinese members of this team of authors as well as one life history interview with a migrant Asian student. Through careful theorisation of the interconnections between the life histories of our participants and their supervision experience, an inventory of supervision strategies will be distilled to improve intercultural supervision. © 2017 by IGI Global.

SAlexNet: Superimposed AlexNet using Residual Attention Mechanism for Accurate and Efficient Automatic Primary Brain Tumor Detection and Classification
No full textAccurate classification of brain tumors is crucial for informing clinical diagnoses and guiding patient treatment plans. It is one of the most aggressive tumors, leading to a short life expectancy. However, the classification of brain tumors is a challenging task due to the heterogeneity, complexity, and variability of brain tumors. In this work, we propose Superimposed AlexNet (SAlexNet-1 and its extension SAlexNet-2) to detect the malignancy of primary brain tumors (Glioma, Meningioma, and Pituitary) by incorporating three enhancements: (1) fusing Hybrid Attention Mechanism (HAM), (2) dense feature extraction by replacing initial convolution 11 × 11 layer with multiple convolution 3 × 3 layers for extra non-linearity alleviating parameter burden, and (3) pretraining the encoder path on a correlated dataset via semi-transfer learning (STL) enhancing model performance. HAM provides more comprehensive and accurate feature representations. In this study, we evaluated the performance of our proposed SAlexNet models on two publicly available extensive datasets for multi-class and binary classification tasks. Our results show that SAlexNet-1 achieved an accuracy of (98.78 ± 0.80 %) and (98.07± 0.02 %) on the multi-class and binary classification datasets, respectively. In comparison, SAlexNet-2 achieved outstanding accuracy of (99.69 ± 0.22 %) and (99.17 ± 0.00 %) on the multi-class and binary classification MRI datasets, respectively. The STL-based SAlexNet-2 surpassed previous literature with complex models and techniques, achieving an accuracy of (99.20 ± 0.01 %). Furthermore, we provided a comprehensive analysis of current state-of-the-art tumor classification methods on the same dataset, demonstrating the effectiveness of our approach. Enhanced tumor classification accuracy enables better diagnosis, treatment planning, and patient outcomes

No full textIt is evident that the Progressive Movement in the Subcontinent started in the objective condition prevailing at that time. In the beginning some men of letters attributed Progressive Criticism to Marxism. But as Dr. Qamar Raees has clarified, it was not a mechanical approach towards criticism. The main emphasis is on social context of literature. In this perspective, two progressive critics, Syed Sibte Hasan and Zoe Ansari can be termed as the important founders of Progressive Criticism in Urdu. Both of them give equal importance to social context of literature as well as the classical and cultural heritage of the society.
Internationalisation and identity: Identity construction through Australian University student mobility program
No full textThis chapter begins with exploring the concept of student mobility historically. Very few studies seek to address students' existing identities and to trace the colonial impulses contained within discourses of internationalisation. Instead, much of the literature is premised on assumptions of the benefits of these programs. In particular, there is an oversimplification of student identities in explorations of student mobility programs. The authors critically synthesise the literature on discourses of internationalisation and develop a conceptual framework to extend present understandings of the impact of student mobility programs on student identity (re)formation. Also, the present New Colombo Plan will be analysed with particular focus on their construction of student identity. The chapter concludes with the argument that the acknowledgement of students' already existing diverse identities could be utilized in internationalisation programs on home campuses and provides a possible roadmap for future directions for outbound student mobility programs. © 2017 by IGI Global.

Characterization of spliceosome assembly in cyanidioschyzon merolae.
No full textPre-mRNA splicing is the removal of intervening sequences from pre-messenger RNA in a reaction catalyzed by the spliceosome, which contains five small nuclear RNAs (snRNAs) and more than 100 proteins. Assembly of the spliceosome occurs in a highly ordered manner, making the spliceosome a very complex and dynamic particle. The spliceosome has been studied in yeast and humans but a simpler system would simplify splicing studies. Cyanidioschyzon merolae (Cm) has been shown to have a simpler spliceosome. The goal of this study was to characterize the Cm spliceosome beginning with the question of how large it is. To measure the size of the Cm spliceosome I used glycerol gradient centrifugation and assembly gels to study the assembly pathways. Lastly an attempt was made to study the components of Cm spliceosome by developing an assay in yeast (Saccharomyces cerevisiae) where small molecule inhibitors were used to stall the spliceososme, which could then be purified and its composition studied. --Leaf ii.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b197654
Etiological Spectrum and Treatment Outcome of Obstructive Jaundice at a University Teaching Hospital in Northwestern Tanzania: A Diagnostic and Therapeutic Challenges.
No full textObstructive jaundice poses diagnostic and therapeutic challenges to general surgeons practicing in resource-limited countries. This study was undertaken to highlight the etiological spectrum, treatment outcome of obstructive jaundice in our setting and to identify prognostic factors for morbidity and mortality. This was a descriptive prospective study which was conducted at Bugando Medical Centre between July 2006 and June 2010. All patients with a clinical diagnosis of obstructive jaundice were, after informed consent for the study, consecutively enrolled into the study. Data were collected using a pre-tested structured questionnaire and analyzed using SPSS computer software version 11.5. A total of 116 patients were studied. Females outnumbered males by a ratio of 1.3:1. Patients with malignant obstructive jaundice were older than those of benign type. Ca head of pancreas was the commonest malignant cause of jaundice where as choledocholithiasis was the commonest benign cause. Abdominal ultrasound was the only diagnostic imaging done in all patients and revealed dilated intra and extra-hepatic ducts, common bile stones and abdominal masses in 56.2%, 78.9%, 58.1% and 72.4% of the cases respectively. A total of 110 (94.8%) patients underwent surgical treatment and the remaining 6 (5.2%) patients were unfit for surgery. The complication rate was 22.4% mainly surgical site infections. The mean hospital stay and mortality rate were 14.54 days and 15.5% respectively. A low haematocrit and presence of postoperative sepsis were the main predictors of the hospital stay (P < 0.001), whereas age > 60 years, prolonged duration of jaundice, malignant causes and presence of postoperative complications mainly sepsis significantly predicted mortality (P < 0.001). Obstructive jaundice in our setting is more prevalent in females and the cause is mostly malignant. The result of this study suggests that early diagnosis and treatment plays an important role in the prognosis of patients with obstructive jaundice
