Published: July 2021

ABSTRACT.
To evaluate percutaneous transsplenic varices embolization (PTSVE) in the treatment of upper gastrointestinal bleeding (UGIB) in patients with chronic hepatic schistosomiasis japonicum (CHS), 29 CHS patients (20 males and 9 females) complicated with UGIB were selected as the investigation subjects. The patients were treated by PTSVE under the guidance of X-ray fluoroscopy. The success rate of PTSVE and the rate of complications were observed. In addition, the degrees of varices before and after PTSVE were evaluated by abdominal computed tomography (CT). Results showed that 26 CHS patients (89.6%) were successfully treated with PTSVE. Three cases (10.3%) failed, and two experienced intraperitoneal bleeding within 1 week after PTSVE. The abdominal CT showed a significant decrease of the varices stage in coronary (P < 0.001), esophageal (P = 0.006), and paraesophageal (P = 0.013) varices, but slightly increased perisplenic varices within 1 month of the intervention (P = 0.014). PTSVE may be a safe and effective procedure for the treatment of UGIB in CHS patients, particularly suitable for those with a widened hepatic fissure and exposed hepatic portal vein trunk and an enlarged spleen.
ATTITUDE OF TEACHERS AND ITS IMPACT ON THEIR INSTRUCTIONAL PRACTICE
Authors: Owusu-Fordjour Collins 
Published: July 2021

<p>This study investigated the attitude of Integrated Science Teachers in Senior High Schools and its impact on their instructional practice. The study employed the quantitative research approach adopting the descriptive survey design. The study employed the use of questionnaire and observation checklist to collect data from 138 participants. This attitude towards the subject stems from the perception these respondents have had about the subject for so many years since perception influences one's attitude towards an event. These attitudes also influence their expectations of how their teaching can effectively help students learn which adversely affects their attitude towards the instructional process. It was also realised that persons’ attitude towards instruction affects the demeanour and how the person carries out the instruction. The study therefore concludes that teacher’s competency and positive attitude towards instructional practice could contribute to effective teaching and students’ achievement. Knowledge on the subject matter of the curriculum that the teachers are required to teach influence the teachers’ own perception of the subject that influences their attitude. Integrated Science teaching skills is highly technical therefore; teachers’ personal development training enhances the content knowledge of teachers in Integrated Science as well as classroom management skills should be enhanced as this will go a long way to impact on the teachers’ attitude in the classroom. </p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0888/a.php" alt="Hit counter" /></p>

A self-evaluation tool of sustainability concepts in higher education institutions courses
Authors: Venezia Elisabetta , Pizzutilo Fabio 
Published: July 2021

In this paper, a self-evaluation tool is developed to allow educators and Higher Education Institutions to assess their efforts in pursuing Education for Sustainable Development. The composite index here proposed allows the individual components that contribute to the pursuit of sustainability in education to be grasped in isolation and, at the same time, provides an overall evaluation measure of all the elements taken into consideration. The index is based on the identification of elements that measure the efficiency of the allocated expenditure. At the same time, it encompasses measures of the impact and perception of sustainability concept by staff and students. Albeit in a laborious way, the application of the tool leads to an unbiased assessment of education for sustainable development results. This composite indicator can be used in a replicative manner elsewhere and offers the advantage of being able to carry out comparative evaluative analyses. This is due to its adaptive flexibility.
Rotating bending load tests of wheels. Methodological errors
Authors: Chelnokov V. G. , Savel'ev B. V. 
Published: July 2021

Introduction (problem statement and relevance). Wheels are components that ensure the safety of vehicles. One of the main ways to test the fatigue strength of wheels is a rotating bending load test. The methodology of these tests, regulated by international and national regulatory documents, allows an indirect method for measuring the normalized force effect on the wheels, in which there are always risks of methodological errors.The purpose of the study was to identify potential sources of methodological errors when testing wheels in the bending-rotating mode.Methodology and research methods. Analytical research methods from the field of practical vibration theory were used in the article, considering the critical state of rotating shafts and rotors. Scientific novelty and results. The sources of potential methodological errors and their relationship with the design characteristics of the bench equipment and the wheel itself were determined.Practical significance. Practical recommendations have been given on the change and control of the stand components design characteristics aimed at minimizing errors. The high-speed test modes were determined, in which the error of the test effect on the wheel did not go beyond the normative limits.

Published: July 2021

Introduction (problem statement and relevance). In recent years, attention to hydrogen as an alternative kind of transport fuel has been increasingly growing as hydrogen is considered to be capable of replacing petroleum traditional fuels. Moreover, it is believed that the use of hydrogen can solve the environmental problems of transport, reduce power plants energy driving costs and solve the problem of fossil resources depletion.The purpose of the study was to analyze hydrogen as a possible alternative fuel, assess its advantages and disadvantages taking into account both the variety of its usage and power environmental and economic aspects of hydrogen production together with problems associated with its practical use.Methodology and research methods. The analysis of hydrogen production has been carried out including its use as a possible fuel for motor vehicles.Results. High energy consumption, environmental imperfection of hydrogen production processes and related problems of its storage, transportation, power units as well as of the scarcity of some necessary resources do not provide grounds for optimistic assessments of economic and environmental assessments of vehicles powered by hydrogen.

CÁNULA NASAL DE ALTO FLUJO EN PEDIATRÍA
Authors: Wegner A Adriana 
Published: July 2021

La Cánula Nasal de Alto Flujo (CNAF) es una modalidad de soporte respiratorio no invasivo cada vez más difundida en la población pediátrica por sus beneficiosos efectos sobre la oxigenación, ventilación y confort del paciente. Sus mecanismos de acción han sido ampliamente estudiados, siendo la generación de presión positiva la que aún genera más controversia.
Si bien aún existe poca solidez de la evidencia respecto a la eficacia y seguridad de la CNAF en la literatura, su facilidad de instalación, mantención y seguridad aparente ha determinado que en varios centros su uso se considere ya un estándar de cuidado “off- label”, factible de utilizar en unidades de menor complejidad, con la consiguiente descompresión de unidades críticas.
Este artículo pretende realizar una puesta al día de la CNAF en cuanto a sus mecanismos de acción, evidencia referente a su utilidad en pediatría, potenciales indicaciones, así como su uso fuera de unidades críticas.
Comparing global seismic tomography models using varimax principal component analysis
Authors: de Viron Olivier , Van Camp Michel , Grabkowiak Alexia , Ferreira Ana M. G. 
Published: July 2021

Abstract. Global seismic tomography has greatly progressed in the past decades, with many global Earth models being produced by different research groups. Objective, statistical methods are crucial for the quantitative interpretation of the large amount of information encapsulated by the models and for unbiased model comparisons.
Here we propose using a rotated version of principal component analysis (PCA) to compress the information in order to ease the geological interpretation and model comparison. The method generates between 7 and 15 principal components (PCs) for each of the seven tested global tomography models, capturing more than 97 % of the total variance of the model. Each PC consists of a vertical profile, with which a horizontal pattern is associated by projection. The depth profiles and the horizontal patterns enable examining the key characteristics of the main components of the models. Most of the information in the models is associated with a few features: large low-shear-velocity provinces (LLSVPs) in the lowermost mantle, subduction signals and low-velocity anomalies likely associated with mantle plumes in the upper and lower mantle, and ridges and cratons in the uppermost mantle. Importantly, all models highlight several independent components in the lower mantle that make between 36 % and 69 % of the total variance, depending on the model, which suggests that the lower mantle is more complex than traditionally assumed. Overall, we find that varimax PCA is a useful additional tool for the quantitative comparison and interpretation of tomography models.
Cartas para minha mãe, de Teresa Cárdenas: racismo e resistência na voz de uma literata negra
Authors: Benatti Andre Rezende , Candido Alcione Rafael 
Published: July 2021

The aim of this work is to analyze racism from the perspective of the main character —a child, black and orphaned— from the novel Cartas para minha mãe, by contemporary Cuban writer Teresa Cárdenas. The narrative develops around a character who did not have what we call childhood today, and who thus enters adolescence. However, our focus will be on the black condition of the narrator, who at all times suffers from the most diverse types of prejudices, in addition to having to deal with a difficult phase: the transition from childhood to puberty. In this way, this work intends to discuss the issues involving childhood surrounded by prejudices of the main character of Cárdenas' novel, while we will observe the reactions and perceptions of the child in face of racism. For the analysis of the novel, the narrator's childhood, the historical contextualization of the colonization process in Latin America and the psychosocial process of the feeling of inferiority of blacks and of superiority of white, we will use the texts of the following scholars: Cabo Aseguinolaza (2001); Ariès (1981); Fanon (2008); Gates (2014) and Souza (2015), among other theoretical texts. In the end, we realized that in the novel by Teresa Cárdenas the weight of racism leads the narrator to seek help in the letters she writes to her dead mother. The racism present in the text builds as a sample of what several people go through every day of their lives.
Death, nursing and writing ambiguous characters
Authors: McAllister Margaret , Brien Donna Lee 
Published: July 2021

When nurses are featured in narratives associated with death and dying, the common stereotype of the good nurse – of mother, or angel of mercy – is often invoked. Although such imaging can be flattering for nurses, whose work might otherwise go unnoticed and unappreciated, this representation is also unrealistic and dehumanising. Darker representations of nurses, and particularly the uncomfortable or profane aspects of nursing work, are not only rare outside of the horror genre, they have also largely escaped examination. Consequently, writers, as well as others including the public and those involved in the practice, teaching and scholarship of nursing, have a limited lexicon with which to describe that large part of nursing work which is situated in the realm of the abject, turbulent and traumatic. This article examines Franco’s film, Chronic (2015), which features a nurse who works in home-based palliative care, and whose character defies stereotypes. Analysing this richly drawn character and what this characterisation reveals about the world in which he operates, provides a case study of writing characters against powerful stereotypes and writing ambiguity.
Illuminations: a proposed taxonomy for death-inspired works in Western art music
Authors: Lodge Martin 
Published: July 2021

Throughout the history of Western art music, death has been a major stimulus for composers, and it continues to be so for contemporary musicians. Composer responses to death have been predominantly associated with emotions of grief, sadness and loss. An examination of responses in the Western art music repertoire of the past five hundred years, however, reveals that there is a diversity of composer reactions, from mourning through prophetic imaginings to resignation, and extending to spiritual affirmation or theological affirmation of an afterlife. Informed by surveying a number of composers’ diverse responses, this article outlines differences found in order to propose a taxonomy of varying creative musical approaches to death.
‘An ambiguous genre’: thoughts on creative non-fiction and the exegesis
Authors: Robertson Rachel , Juckes Daniel , O’Rourke Marie , Pettitt-Schipp Renee 
Published: July 2021

The requirement for separate creative and exegetical components by universities offering creative doctoral programmes is a largely accepted model in Australia. The Research Question Model adopted by Curtin University in Western Australia is an example of this. The parallel, ‘independent’ articulation of creative and academic responses is explored in this article by a supervisor and three PhD candidates all writing in the genre of creative non-fiction. We suggest that the boundaries between the scholarly and creative in creative non-fiction works are far from clear and that this reflects both contemporary non-fiction publishing and new movements in scholarly writing. We propose that Barthes’s ‘ambiguous genre’, the essay, may be one useful way of conceptualising the non-fiction creative doctorate.
Exegetical essentials: a framing structure and template for a comprehensive exegesis in the creative arts
Authors: Brien Donna Lee , Owens Alison , Pittaway Gail , Waters Irene 
Published: July 2021

For over two decades, the number of candidates undertaking, and completing, research higher degrees in the discipline of creative arts has continued to grow, yet the anxiety associated with the exegesis, or critical component, to the award has not dissipated. This article reports the views of a small number of research higher degree candidates and their supervisor in response to questions posed by the TEXT ‘Exegesis now’ call for papers. In this sample, the exegesis was perceived as a necessary and useful component to the award by all respondents, who are completing diverse creative projects. However, respondents also express some anxiety and uncertainty over what is required in the exegesis in terms of formal, structural and compositional elements. Discussion of the views expressed by respondents identifies common challenges and proposes a number of strategies that may provide greater certainty and alleviate some of the anxiety for candidates and their supervisors. It includes a template for a comprehensive exegesis and two ways the exegesis can be structured to form a rigorous frame around, and supportive complement to the creative work.
Contributing to knowledge in creative writing research: what, where, how?
Authors: Batty Craig , Holbrook Allyson 
Published: July 2021

There is general agreement that doctoral research should show ‘originality’, but there is less agreement about what that means or how it is distinguished from ‘contribution’. There is also a strand in the literature that attests that different disciplines, especially relative newcomers to the doctorate such as the creative arts, privilege different qualities of originality and forms of contribution. This prompts the question: what constitutes an original contribution in the field of creative writing? Drawing on the growing literature on creative doctorates, reference to a number of examiner reports collected for a larger project, and reflections on supervising and examining creative writing PhDs, this paper explores the various forms of contribution that characterise the discourse on knowledge creation and dissemination in creative writing research.
Crafting Baba Yaga from the Australian landscape: An interview with Lorena Carrington
Authors: Do Rozario Rebecca-Anne , Carrington Lorena 
Published: July 2021

The Australian fairy-tale tradition is as much about art as literature. This interview engages with how one artist physically draws upon the Australian landscape to retell iconic imagery from European fairy tale and folklore and how she sees her work in relation to contemporary writers. Australian fairy tale is in open negotiation with the history of the landscape and finding the stuff of fairy tale in the rocks, leaves, bones and debris of the landscape allows Carrington to craft work that engages with old European traditions while connecting to Australia’s material presence and looking forward to our innovative future in the genre.
Of education, the bush and other strange creatures: Environmental conservation in Australian fairy tales
Authors: Snell Catherine 
Published: July 2021

Fairy tales were late to appear in the Australian context but they quickly reflected contemporary concerns over the treatment of the native flora and fauna. Writers of early Australian fairy tales promoted the conservation of the Australian environment, educated children in the realities of living in the harsh Australian landscape and warned of the dangers that humans posed to the native animal population. This article posits that this movement in fairy tales was due to contemporary changes in curriculum and attitudes towards children’s education, and a growing sense of nationalism postFederation in 1901 that tied the Australian identity to the landscape.
Strategic, stylistic and notional intertextuality: Fairy tales in contemporary Australian fiction
Authors: Wood Danielle 
Published: July 2021

While Canadian scholar Lisa M Fiander argues that fairy tales are ‘everywhere’ in Australian fiction, this paper questions that assertion. It considers what it means for a fairy tale to be ‘in’ a work of contemporary fiction, and posits a classificatory system based on the vocabulary of contemporary music scholarship where a distinction is made between intertextuality that is stylistic and that which is strategic. Stylistic intertextuality is the adoption of features of a style or genre without reference to specific examples, while strategic intertexuality references specific prior works. Two distinct approaches to strategic fairy-tale revision have emerged in Australian writing in recent decades. One approach, exemplified in works by writers including Kate Forsyth, Margo Lanagan and Juliet Marillier, leans towards the retelling of European fairy tales. Examples include Forsyth’s The Beast’s garden (’Beauty and the Beast’), Lanagan’s Tender morsels (‘Snow White and Rose Red’) and Marillier’s short story ‘By bone-light’ (‘Vasilisa the Beautiful’). The other, more fractured, approach is exemplified in works by writers including Carmel Bird and Murray Bail, which do not retell fairy tales but instead echo them and allude to them. This paper proposes that recent Australian works that retell fairy tales are less likely to be set in a recognisably Australian context than are works which take a more fractured approach to fairy tale. It also explores the notion that, presently, transporting European fairy tales, whole, into an Australian setting, seems to be a troubling proposition for writers in a post-colonial settler society that is highly sensitised to, but still largely in denial about, its colonial past.
Historia organów w kościele pw. św. Wojciecha i Matki Bożej Bolesnej w Modlnicy
Authors: Matoga Piotr 
Published: July 2021

Przedmiotem artykułu jest historia organów w kościele pw. św. Wojciecha i Matki Bożej Bolesnej w Modlnicy. Tekst oparty jest na rezultatach kwerend archiwalnych, przy czym najwięcej źródeł pochodziło z archiwum parafialnego. Podjęte badania wykazały, że organy w rzeczonej świątyni istniały co najmniej od pierwszej połowy XVIII w. Obecny instrument zbudował w latach 1843–1844 krakowski organmistrz Ignacy Wojciechowski. Organy te były wielokrotnie naprawiane, remontowane i przebudowywane. W 1888 r. renowację przeprowadził syn ichbudowniczego, Tomasz Wojciechowski z Krakowa, natomiast w drugiej połowie XX w. firma Henryka Siedlara z Krakowa rozbudowała instrument o sekcję pedału. Artykuł stanowi przyczynek do historii życia muzycznego w parafii modlnickiej oraz do biografii Ignacego i Tomasza Wojciechowskich.
