Designing active Maths for undergraduate STEAM students
Authors: Brunetto Domenico , Moura Santos Ana
Published: July 2021

This work presents a set of student-centred activities that may help undergraduate students understand mathematics in their first year of a STEAM degree. In particular, the authors refer to the difficulties students meet in making connections between syntactic and semantic dimensions in learning mathematics, especially in Linear Algebra topics. The specific goal of this paper is to present and discuss how it can work in the case of linear transformations. This topic stands in the middle of every Linear Algebra standard course and is pivotal in many recent applications, such as computer graphics. The study describes the teaching-learning experience and reports the results of the first pilot study, which involves about 100 undergraduate Architecture students of Politecnico di Milano. One of the peculiarities of this work is its context since the class is composed of heterogeneous group of students, in terms of knowledge background and attitudes towards mathematics. The main findings of this paper are underlining how a student-centred strategy, based on asynchronous activities and synchronous class discussion, allows misconceptions to emerge and be appropriately addressed
Assessing Database Development Skills using an On-line MCQ: Reflections on Test Design and Academic Integrity
Authors: Lang Michael
Published: July 2021

This paper reports on the experiences of assessing a large postgraduate module in Database Systems using an on-line MCQ test under COVID-19 conditions with no remote proctoring. While the technology and the “higher order thinking” assessment worked well, analysis of response patterns suggested that, despite the use of randomised questions, time pressure and an honour pledge, a substantial number of students formed mini-networks during the test and colluded with each other to discuss the answers. No differences by gender or age were observed as regards tendency to engage in this behaviour, and domestic students were just as likely as international students to do it. Notably, domestic and international students seemed to stay apart, colluding almost exclusively with others of their own nationality.

Published: July 2021

On the wings of New Public Management (NPM) and the Bologna Process, Higher Education Institutions (HEI) needed to innovate towards market orientation, both students demanding and social relevance. One way to achieve these objectives is through co-creation processes, involving students and partners outside as companies and public institutions. The purpose of this paper is to assess the satisfaction of Instituto Politécnico de Bragança (IPB) students who actively participated in a co-creation process called Demola, which aims the pedagogical innovation and strengthening the link with and the community. Quantitative data was collected through an online survey that included questions about students' perception on the impact of the co-creation process Demola. The population is 250 students who participated in eight batches in the last four years, working in 44 co-creation cases or challenges. 87 students answered the questionnaire, corresponding to 34,8% of the sample. Main results and conclusions suggested high levels of satisfaction among IPB students’ and are perceived as having very positive impact in skills’ development.
Linking teachers’ facial microexpressions with student-based evaluation of teaching effectiveness: A pilot study using FaceReader™
Authors: Schlag Ruben , Sailer Maximilian
Published: July 2021

This study seeks to investigate the potential influence of facial microexpressions on student-based evaluations and to explore the future possibilities of using automated technologies in higher education. We applied a non-experimental correlational design to investigate if the number of videotaped university lecturers’ facial microexpressions recognized by FaceReader™ serves as a predictor for positive results on student evaluation of teaching effectiveness. Therefore, we analyzed five videotaped lectures with the automatic facial recognition software. Additionally, each video was rated by between 8 and 16 students, using a rating instrument based on the results of Murray´s (1983) factor analysis. The FaceReader™ software could detect more than 5.000 facial microexpressions. Although positive emotions bear positive influence on the “overall performance rating”, “emotions” is not predicting “overall performance rating”, b = .05, t(37) = .35, p > .05. The study demonstrates that student ratings are affected by more variables than just facial microexpressions. The study showed that sympathy as well as the estimated age of the lecturer predicted higher student ratings.
Using Online Forums to Promote Collaborative Learning in Introductory Programming Courses
Authors: Michaličková Viera
Published: July 2021

The asynchronous online discussion can enrich learning experience in many ways, even in classroom or blended learning scenarios. It is quite challenging to design an effective online discussion. The presented study draws on the action research strategy. After observing and analyzing students’ learning problems in introductory programming courses, we came up with intervention of the online collaborative activity to guide students during their individual studying at home in a more regulative manner. The main goal was to involve students in active learning and strengthen the feel of being a friendly community member. Students were producing sample test questions/tasks for others, and then using products of their classmates for their own learning. The intervention was evaluated deeply using both, qualitative and quantitative methods. This reflection implied that the activity’s design was appropriate and the impact on students’  learning process was positive. We found the constructivist features of the activity essential as for its effectiveness. The learning scenario described in this paper provides a verified framework for designing similar collaborative activities suitable mainly for problem-oriented areas of study, e. g. in science or engineering education.

Published: July 2021

This work aims to inspire, ignite and engage school students to consider STEM at university, by collaborating between a university research group and school students. Learning resources will be co-created with students, based on what they have learnt and their new ideas. These resources will be used to teach future students, in a multiplying effect. We specifically target a widening participation school. Numerous engagement techniques have been used to sustain participation whilst teaching online. Breakout rooms have been used extensively, to provide close interactions between researchers and students. Both male and female researchers deliver the project, to provide role models in particular for the girls amongst the students, who are in the minority. Surveys are being employed before, during and after the project to evaluate the evolution of students’ attitudes towards STEM. Given the projected success of this pilot, plans are in place for a national roll-out of virtual co-creation collaborations.

Personal Employability and employment outcomes in a university sample: a study before and after COVID-19
Authors: Tomás Inés , Hernández Ana , Davcheva Marija , González-Romá Vicente
Published: July 2021

Labour market uncertainty makes difficult to get (and keep) a high-quality job even for graduate students. Moreover, this situation has been worsened due to the COVID-19 pandemic. The aim of this study is to test the influence that personal employability has on maintaining (or being able to find a new) high-quality job in a sample of young university graduates that faced the job market crisis caused by the COVID-19 pandemic. We focus on the four personal employability dimensions of Fugate et al.’s (2004) model: career identity, personal adaptability, human capital, and social capital. Our hypotheses state that the four dimensions of employability are positively related with employment status and with job quality indicators (salary, horizontal fit, job satisfaction). The results obtained in a sample of 136 university graduates show that social capital contributes to being employed after several months of job market uncertainty caused by COVID-19. Moreover, career identity positively predicts horizontal fit and job satisfaction. The study shows the importance of social capital and career identity under uncertain job market situations to foster positive employment outcomes.
Development and Evaluation of Online Approaches for Improved Kinaesthetic Learning in Science
Authors: Scanlan Anna M. , Kennedy Declan , McCarthy Tommie V.
Published: July 2021

Kinaesthetic learning is expressed when physical actions are used to connect concept development to reality, for example through model building, trial and error practice, or role-play interactions. Learning through a kinaesthetic modality is highly effective and complementary to other learning modalities. Recent advances in gamification for education have increased access to science simulations and learning online. However, the transfer of offline kinaesthetic techniques to online learning remains under-researched and poorly implemented on affordable, scalable platforms. Here we describe an accessible approach for educators on how to incorporate online kinaesthetic aspects into lessons through use of a scalable and affordable framework developed called the ‘Kinaesthetic Learning System’ (KLS). This framework should be of particular use for learning complex molecular life science topics but can be adapted and modified independently by the educator to address different knowledge levels and for expansion to other disciplines.
Proposal for an intelligent digital teacher’s textbook solution adapted to the Bachelor-Master-Doctorate system
Authors: Boko Ulrich Hermann Semevo , Degboe Bessan Melckior , Ouya Samuel , Mendy Gervais
Published: July 2021

This paper proposes an intelligent solution for course monitoring based on the use of a digital textbook coupled with an algorithm for verifying the conformity of the teaching content. The proposed solution allows to follow in real time the evolution of the courses and to alert the pedagogical managers in case of non-compliance with the syllabus. In most sub-Saharan African countries engaged in the Bachelor-Master-Doctorate (BMD) reform, incessant strikes prevent teachers from completing the program. Also, there is no way for the teacher to know whether students have the necessary prerequisites. In addition, constraints related to agendas sometimes prevent the holding of pedagogical animation meetings. To solve these problems, we propose the implementation of an intelligent digital teacher's textbook. The tool helps in the follow-up and the respect of the pedagogical objectives. It implements an algorithm to evaluate in real time the concordance between the courses given and the requirements of the syllabus. An SMS and e-mail alert system has also been set up to inform training actors in case of non-compliance with the syllabus. The proposed solution contributes to the overall improvement of the quality of higher education in Saharan Africa.

This paper addresses  the methodology of Design Thinking and its applicability as a creative methodology when teaching and learning Sociology of Childhood in a higher education context. Students were asked to develop an exercise in order to expand and deepen the theoretical and conceptual knowledge discussed in theoretical classes. Active and creative methodologies were specifically and purposefully designed to develop the ability to think critically about the problems presented, stimulating debate and sociological imagination. Inspired by the Mindshake Design Thinking Model Evolution 6², practical classes were organized and oriented towards specific techniques, namely the “Inspiration Board”, “Intent Statement” and “Insight Clustering”, following, respectively, the phases of exploration, data collection and analysis and interpretation of results. Illustration is given through the development of a research itinerary committed to think, discuss and creatively research the meanings of the “dark” and “darkness” of the night for children. Incorporating Design Thinking in the teaching and learning process in the field of social sciences, namely when researching children and childhood from a sociological perspective, proved to be a both fruitful and engaging tool both for teachers and students.
Technology as gamification means in mathematics learning
Authors: García-Hernández Alién , González-Ramírez Teresa
Published: July 2021

Discrete Mathematics is a highly complex university subject. His classes are taught in a traditional way, so in many cases they do not motivate students. This study develops dynamics of gamification to promote a better learning of Discrete Mathematics, in the same way, it seeks to influence the engagement of students in this university subject. 178 students participate in this quasi-experiment (90 in the control group and 88 in the experimental group). The pretest and posttest data of the academic performance and engagement of the experimental group and the control group display that, in terms of progress, the experimental group showed significant progress compared with the control group. The study is concluded by raising the possibility of applying other games and game dynamics that promote a greater variety of gamified activities. In this sense, it is proposed to investigate the effects of the use of games in mobile application format on both engagement and academic performance in Discrete Mathematics.

Published: July 2021

As health professionals, nurses are responsible not only for staying abreast of current professional knowledge to provide effective care but also for managing their own career, professional growth and development. Nurse educators have acknowledged that eportfolios provide a means through which nurses can record and provide evidence of skills, achievements, experience, professional development and, on-going learning, not only for themselves, but for the information and scrutiny of registration boards, employers, managers and peers. Recognising that practices to support these activities that foster 21st century learning should ideally start during their student years, the authors explored eportfolios as a valuable learning device for on-going personal and professional development for fostering students’lifelong learning and enhancing continuous personal and professional development. This paper describes the critical success factors for successful implementation of the Google Sites Practice eportfolio embedded in the three-year BSc(Hons) Nursing Programme in Malta. Evidence-based practice of successful eportfolio implementors was examined and their methods adapted to ensure the initiative had a sound foundation and fit for purpose.The authors argue that to be successful, eportfolio implementation must primarily be strategic, holistic, supported and have senior management buy-in and secondarily, have a robust tool, good pedagogy, and skilled and enthusiastic staff.

Though it is generally agreed upon that the Greeks borrowed (and modified) the alphabet from the Phoenicians, there is no consensus about the moment when this took place. Over the years, several dates have been proposed, ranging from the 14th to the 8th  7th century BCE. In classical studies the prevalent opinion is that the alphabet was introduced in or shortly before the 8th century BCE, when the first attestations of Greek alphabetic writing appear. There are, however, quite a number of indications (from existing and new evidence) that plead for a much earlier date. In this article, an analysis of the presently available archaeological, epigraphic and linguistic data will be presented to argue the case for an introduction in the 11th century BCE at the latest. The earliest documents, which were in all likelihood economic and administrative records, have not come down to us, because they were written on perishable materials.

Published: July 2021

Mental disorder is becoming one of the major health issues in society today. (WHO) depression will be the leading mental disorder all over the world by 2030. The timely prediction of such disorders is very essential for maintaining the health of human beings. These mental disorders are associated with different symptoms, some of these symptoms are visible in the form of facial expressions, gestures, change in voice modulation, etc. and some of them even cannot be noticed by naked eyes. Therefore, it is highly important to collect appropriate verbal and non-verbal symptom details about any individual along with using best-suited algorithms for accurate prediction using information technology. This paper explores different types of such symptoms associated with different types of mental disorders, their causes, and existing prediction-based solutions. The paper further presents the critical analysis of these aspects and proposes usages of biometrics-based traits for building better prediction systems for mental disorders.

This section is devoted to the study of the measuring area in which topology set X is produced by an unused scalar known as metric that can be defined as a measurement of a particular distance between any two parts, or focused, in the setting as part of its properties strongly suggests the natural concept of distance we usually experience. In everyday life. This type of climatic space includes a popular position among all technological spaces because the reason is that its topology has been completely removed by scale-level work. We can confidently assume that we are well acquainted with the characteristics of such work and are accustomed to handling it. All things being equal, perfect topology is often commended by a certain category of a small dynamic subset of a theoretical set. The concept of measurement space was first introduced by Fréchet in the year 1906. However, the name of the metric space was given by Hausdorff later.

Published: July 2021

In the conducted studies on sod-podzolic soils and ordinary chernozems, a change in the rate of transition of Ca, Md, Fe, K ions from the soil to H2O at temperatures of 0 and 20º, the interaction time of 1 day and 1 week was established. It is shown that the speed of the processes depends on the combination of temperature and duration of reactions, differs for individual soils, horizons and certain cations. The magnitude of the change in the rate of the processes under consideration does not fully correlate with the physico-chemical and thermodynamic patterns of changes in the mobility of ions in soils depending on humidity and temperature, which is associated with the simultaneous course of ion exchange reactions, complex formation, sedimentation. The necessity of studying the kinetics of processes occurring in the soil for a more correct assessment of the agroecological state of soils is proved.

A pesar de los avances en cuidados intensivos, el weaning pediátrico aún tiene un componente importante de arte. A diferencia de los adultos, aún no contamos con índices predictores o protocolos precisos y confiables, que ofrezcan algún aporte que supere el juicio clínico. Se distinguen 2 tipos de falla: weaning, previo a la extubación, y la de extubación. Esta última, con un rango entre 4.1 -19%, muestra asociación con edad, tiempo de ventilación mecánica y en menor cuantía, al tiempo y cantidad de sedantes utilizados. Como elemento causal único de mayor importancia se describe a la obstrucción de la vía aérea alta. Al igual que en el weaning, aún no contamos con criterios y pruebas predictivas precisos, pero algunos elementos pueden ayudar a la toma de decisiones.

Published: July 2021

Abstract. In this study, meat quality traits and fatty acid compositions of Hair Goat and Saanen × Hair Goat (G1) crossbred kids fattened
under intensive, semi-intensive and extensive conditions were determined. For meat quality traits, differences in pH24 h,
pH45 min, drip loss, water holding capacity, cooking loss and Warner–Bratzler peak shear force values of the experimental groups were
not found to be significant. According to colour measurements at the 0th and 45th minute, the extensive fattening group of Hair Goat kids had greater
lightness (L∗) values and the intensive fattening group of Hair Goat kids had greater redness (a∗) values. For intensive, semi-intensive
and extensive fattening groups of Hair Goat kids, total saturated fatty acid contents of longissimus dorsi (LD) muscle samples were
respectively measured as 19.28 %, 23.75 % and 23.35 %. Total monounsaturated fatty acid contents were respectively measured as 67.30 %,
66.22 % and 65.72 %. Total polyunsaturated fatty acid contents were respectively measured as 5.46 %, 3.06 % and 3.16 % and conjugate
linoleic acid contents were respectively measured as 0.48 %, 0.55 % and 0.65 %. For intensive, semi-intensive and extensive fattening
groups of Saanen × Hair Goat (G1) kids, total saturated fatty acid contents of LD muscle samples
were respectively measured as 21.01 %; 21.98 %, 19.10 %; total monounsaturated fatty acid contents were respectively measured as
64.04 %, 64.33 %, 52.44 %. Total polyunsaturated fatty acid contents were respectively measured as 3.53 %, 4.89 % and 4.84 %
and conjugate linoleic acid contents were respectively measured as 0.52 %, 0.58 % and 0.73 %. It was concluded that the extensive fattening

Published: July 2021

Abstract. Volcanic eruptions can cause significant disruption to society, and numerical models are crucial for forecasting the dispersion of erupted material. Here we assess the skill and limitations of the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME) in simulating the dispersion of the sulfur dioxide (SO2) cloud from the 21–22 June 2019 eruption of the Raikoke volcano (48.3∘ N, 153.2∘ E). The eruption emitted around 1.5±0.2 Tg of SO2, which represents the largest volcanic emission of SO2 into the stratosphere since the 2011 Nabro eruption. We simulate the temporal evolution of the volcanic SO2 cloud across the Northern Hemisphere (NH) and compare our model simulations to high-resolution SO2 measurements from the TROPOspheric Monitoring Instrument (TROPOMI) and the Infrared Atmospheric Sounding Interferometer (IASI) satellite SO2 products. We show that NAME accurately simulates the observed location and horizontal extent of the SO2 cloud during the first 2–3 weeks after the eruption but is unable, in its standard configuration, to capture the extent and precise location of the highest magnitude vertical column density (VCD) regions within the observed volcanic cloud. Using the structure–amplitude–location (SAL) score and the fractional skill score (FSS) as metrics for model skill, NAME shows skill in simulating the horizontal extent of the cloud for 12–17 d after the eruption where VCDs of SO2 (in Dobson units, DU) are above 1 DU. For SO2 VCDs above 20 DU, which are predominantly observed as small-scale features within the SO2 cloud, the model shows skill on the order of 2–4 d only. The lower skill for these high-SO2-VCD regions is partly explained by the model-simulated SO2 cloud in NAME being too diffuse compared to TROPOMI retrievals. Reducing the standard horizontal diffusion parameters used in NAME by a factor of 4 results in a slightly increased model skill during the first 5 d of the simulation, but on longer timescales the simulated SO2 cloud remains too diffuse when compared to TROPOMI measurements. The skill of NAME to simulate high SO2 VCDs and the temporal evolution of the NH-mean SO2 mass burden is dominated by the fraction of SO2 mass emitted into the lower stratosphere, which is uncertain for the 2019 Raikoke eruption. When emitting 0.9–1.1 Tg of SO2 into the lower stratosphere (11–18 km) and 0.4–0.7 Tg into the upper troposphere (8–11 km), the NAME simulations show a similar peak in SO2 mass burden to that derived from TROPOMI (1.4–1.6 Tg of SO2) with an average SO2 e-folding time of 14–15 d in the NH. Our work illustrates how the synergy between high-resolution satellite retrievals and dispersion models can identify potential limitations of dispersion models like NAME, which will ultimately help to improve dispersion modelling efforts of volcanic SO2 clouds.
Assessing the Feasibility of Using a Neural Network to Filter OCO-2 Retrievals at Northern High Latitudes

Published: July 2021

Abstract. Satellite retrievals of XCO2 at northern high latitudes currently have sparser coverage and lower data quality than most other regions of the world. We use a neural network (NN) to filter OCO-2 B10 bias-corrected XCO2 retrievals and compare the quality of the filtered data to the quality of the data filtered with the standard B10 quality control filter. To assess the performance of the NN filter, we use Total Carbon Column Observing Network (TCCON) data at selected northern high latitude sites as a truth proxy. We found that the NN filter decreases the overall bias by 0.25 ppm (~50 %), improves the precision by 0.18 ppm (~12 %), and increases the throughput by 16 % at these sites when compared to the standard B10 quality control filter. Most of the increased throughput was due to an increase in throughput during the spring, fall, and winter seasons. There was a decrease in throughput during the summer, but as a result the bias and precision were improved during the summer months. The main drawback of using the NN filter is that it lets through fewer retrievals at the highest latitude Arctic TCCON sites compared to the B10 quality control filter, but the lower throughput improves the bias and precision.

Published: July 2021

Abstract. Many thousands of large dam reservoirs have been constructed worldwide during the last seventy years to increase reliable water supplies and support economic growth. Because reservoir storage measurements are generally not publicly available, so far there has been no global assessment of long-term dynamic changes in reservoir water volume. We overcame this by using optical (Landsat) and altimetry remote sensing to reconstruct monthly water storage for 6,743 reservoirs worldwide between 1984 and 2015. We relate reservoir storage to resilience and vulnerability and analyse their response to precipitation, streamflow and evaporation. We find reservoir storage has diminished substantially for 23 % of reservoirs over the three decades but increased for 21 %. The greatest declines were for dry basins in southeastern Australia (−29 %), the USA (−10 %), and eastern Brazil (−9 %). The greatest gains occurred in the Nile Basin (+67 %), Mediterranean basins (+31 %) and southern Africa (+22 %). Many of the observed reservoir changes were explained well by changes in precipitation and river inflows, emphasising the importance of multi-decadal precipitation changes for reservoir water storage, rather than changes in net evaporation or (demand-driven) dam water releases.

Abstract. The main object of the present work was to study the role of morphodynamic changes in the flooding of a dissipative beach with microtidal regime, considering the simultaneous and individual effects of erosion and flooding in scenarios of long-term mean sea level rise. For this analysis, we selected a sector of the Colombian Caribbean coast with great touristic, historical, economic, cultural and social importance, namely, Cartagena de Indias; specifically, the beach of Bocagrande. By simultaneously considering erosion and flood processes associated with highly energetic waves, the study facilitates the construction of more precise models for assessing threats to coastal zones. SWAN and XBeach nested models were carried out in order to predict morphological changes and flooding during selected cold fronts and hurricanes that affected Cartagena de Indias; those numerical models were calibrated using field campaigns data (pre- and post-storm). The results of this research indicate that flooding on microtidal dissipative beaches under extreme wave conditions should be approached by considering morphodynamics, because ignoring them can underestimate flooding by ~15%. The erosion and flood effects are intensified by sea level rise, resulting in the most unfavorable condition when extreme events are contemporaneous with high tides.
Una película de Robert Flaherty, en la pampa, filmada por Sergei Eisenstein, para Victoria Ocampo, a espaldas de Waldo Frank
Authors: Oubiña David
Published: July 2021

Victoria Ocampo meets Sergei Eisenstein in New York, in 1930. He is on his way to Hollywood where he plans to make a film and she is there to meet Waldo Frank and discuss the project of the journal Sur. Ocampo invites the filmmaker to come to Argentina make a film about the pampas. The aim of this article is to reconstruct the relationship between the writer and the filmmaker in order to support the hypothesis that we might identify some traces of that project in the film Eisenstein engages with when his trip to Argentina fails: ¡Que viva México!.
Afectividades y desplazamientos escriturales en la obra de Nona Fernández
Authors: Barrientos Mónica
Published: July 2021

Nona Fernández's work has been catalogued within what is known as the "generation of the children" to refer to those narrations by authors who were children during the Chilean dictatorship. The work of the Chilean writer Nona Fernández will be analyzed to understand how the writing process, its relationship with the event and the processes of subjectivation of the characters, from a narrative perspective towards the autobiographical and autofictional genres, have been crossed by fiction to question the constructed certainties and the failures of memory. We will focus mainly on two works which have a thread of narratological and historical continuity, such as Space Invader (2013) and La dimensión desconocida (2016). Both works are related by the terrible events that happened during the Chilean dictatorship. Everything narrated in a cyclical time, like an unknown dimension, living in the present the horrors that we thought were past.
Le langage comme pouvoir de création normé. À propos des cours de Paul Ricœur sur le langage (1962-1967)
Authors: Tétaz Jean-Marc
Published: July 2021

Between 1962 and 1967/68, Ricœur devoted several courses to the question of language. Even though there are many traces of these lectures in the articles and essays published during these years (and collected in part in The Conflict of Interpretations), they have so far attracted little attention from the research community. However, they mark a decisive turning point in Ricœur’s thinking and lay the systematic foundation of the hermeneutics of the text that he would deploy in his later works. The article first clarifies the place occupied by these courses in Ricœur’s work. It then presents the archival material and characterizes the specific approach of each of the courses on the basis of Ricœur’s preparatory manuscripts. In a final section, three particularly instructive aspects of the courses are discussed: the shift from symbol to metaphor (in discussion with Greimas and Jakobson), the articulation of analytic philosophy and phenomenology (Frege and Husserl), and finally the program of a transcendental foundation of the rules of discourse production (Strawson, Wittgenstein and Chomsky).
Présentation: Paul Ricœur, “La question coloniale”
Authors: Wolff Ernst

La cuestión colonial
Authors: Ricœur Paul
Published: July 2021

In this anti-colonial treatise, Ricœur reflects on the responsibility of every French citizen and of the French state with respect to colonialism. He establishes five principles that should guide his readers in their reflection on this issue and expresses his support for the independence of the colonies.
Both sides now: the fear-less exegesis
Authors: Cosgrove Shady , Scrivenor Hayley
Published: July 2021

Fear is an overlooked aspect of the PhD experience, both for the creative writing doctoral

candidate and the supervisor. The exegesis can be a source of fear precisely because of

questions around what it is and what it should look like. Drawing on experiences on both

sides of the supervisory relationship, this article proposes that clear structural models for

the exegesis allow students to focus their efforts on the substance of the academic

component of their research project. We also argue for the rewarding nature of a research

project that engages both in practice-led research and critical scholarship. We propose

that alternating between the exegesis and the creative project can yield surprising results

for creative writers attempting a large-scale academic work for the first time
Talking it over: the agony and the ecstasy of the creative writing doctorate
Authors: Webb Jen , Williams Jordan , Collis Paul
Published: July 2021

This article is co-authored by three writer-academics who have been collaborating as

supervisors, doctoral candidates and co-authors over the past decade. Jen Webb

supervised Jordan Williams during her creative PhD in digital poetry and Deleuze

(awarded 2006); Jordan and Jen co-supervised Paul Collis’s creative PhD in fiction and

Barkindji identity (awarded 2016); and he has long supervised both Jen and Jordan in

their (informal) education in Indigenous epistemology. Over these years, the

supervisor-candidate relationships have unfolded, developed, changed and folded back

on themselves. We explore how this long-term relationship between three mature-aged

writers and scholars, from three very different cultural backgrounds, has inflected our

individual approaches to the preparation and writing of creative research, including the

exegesis. We begin, therefore, with our own understandings of what the word

‘exegesis’ means to us, how it mobilised (or hindered) the generation of creative

knowledge, what models are of value to us, and what we envisage as its possible

future/s. We write this in the form of a three-way conversation, with scholarly

annotations.
The exegesis and co-authorship: collaboration between supervisors and research students
Authors: Krauth Nigel , Bowman Christopher , Fraser Zoe
Published: July 2021

Issues associated with collaborative writing and publishing between supervisors and their

students revolve around the equal, or unequal, participation of the co-authors in the

conception, writing and funding of the work produced. Significant to candidature coauthorship are: co-writing in the academic context generally; co-writing as a social

process; and co-writing in the postgraduate context specifically. This article examines

co-writing in the supervisory space and in particular the doctoral exegesis as a site

suitable for fostering co-writing between students and staff members. Many benefits

derive from co-authoring, and especially for doctoral students after graduation:

employability.
