12 principles for the effective supervision of creative practice higher research degrees, dispatches from the field

In late 2012 and early 2013 we interviewed 25 experienced and early career supervisors of creative practice higher research degrees. This journey spanned five universities and a broad range of disciplines including visual art, music, performing art, new media, creative writing, fashion, graphic design, interaction design and interior design. Some of the supervisors we interviewed were amongst the first to complete and supervise practice-led and practice-based PhDs; some have advocated for and defined this emergent field; and some belong to the next generation of supervisors who have confidently embarked on this exciting and challenging path. Their reflections have brought to light many insights gained over the past decade. Here we have drawn together common themes into a collection of principles and best practice examples. We present them as advice rather than rules, as one thing that the supervisors were unanimous about is the need to avoid proscriptive models and frameworks, and to foster creativity and innovation in what is still an emergent field of postgraduate supervision. It is with thanks to all of the supervisors who contributed to these conversations, and their generosity in sharing their practices, that we present their advice, exemplars and case studies.

Developing learning cohorts for postgraduate research degrees

Development of researchers through higher degree research studies is a high priority in most universities. Yet, research about supervision as pedagogy and models of supervision is only recently gained increasing attention. Charged with producing good researchers within very limited resources, academics are constantly looking for more efficient models of supervision for higher degree research students. A cohort model of supervision promises several efficiencies, but we argue that its success lies importantly on how well the cohort is developed specifically for higher degree research studies. We drew on a growing body of literature on higher degree research supervision to design, implement and evaluate our approach to developing a cohort of seven students enrolled in the Master of Education (Research) degree. Our approach included four provisions: initial residential workshop, development of a learning community, nourishing scholarship, and ongoing learning opportunities. The four provisions resulted in gradually developing an environment and culture that students found very supportive and nurturing. This paper is based on the findings from data collected from student evaluations in the first year of studies, feedback from the cohort’s sponsor, and our reflective notes. The evaluation substantiated the value in investing time and resources for purposely developing a cohort for higher degree research studies. Whether the cohorts are sponsored or not, universities will still need to invest time and resources for cohort development if a cohort model is intended to gain wider efficiencies in supervision of higher degree research students.

Degrees of difference? A preliminary study of criminology degrees at Australian universities

While the discipline of ‘criminology’ has existed within Australian universities for more than half a century, the introduction of discrete ‘criminology’ and justice programmes is much more recent. Little is known, however, about the current state of play when it comes to what a degree in ‘criminology’ actually entails. With growing student enrolments in such programmes, reflecting on the status of these programmes is important in the context of student and employer requirements and expectations. Drawing on the findings of a preliminary study, this paper will explore what it means to study for an undergraduate degree in ‘criminology’ in Australia. Specifically, we will focus on the content, availability and range of ‘criminology’ and justice degrees available in Australia, in order to gain a better understanding of the convergences and divergences across degree programmes, and make some recommendations for future research.

Good Practice Report : Postgraduate Research and Coursework Degrees

Over the past decade, enrolments in postgraduate courses in Australian universities have risen by 34% (or from 258,164 in 2004 to 347,363 in 2013) (uCube, 2014). This substantial growth can be attributed to increased demand for postgraduate coursework as continuing professional education, the expansion of Higher Degrees Research (HDR) intakes, and the development of postgraduate research and coursework degrees in new fields. At the same time, the establishment of the Australian Qualification Framework (AQF) and national Tertiary Education Quality and Standards Agency (TEQSA), as well as the internationalisation of postgraduate education, have brought challenges and opportunities to the sector. During the past five years, the Australian Government Office for Learning and Teaching (OLT) and its predecessor bodies have funded a number of projects and Fellowships on postgraduate coursework and research degrees. They span diverse topics–from entry pathways and research training to supporting international and Indigenous students, examination, scoping studies of new and emergent programs, and effective supervision. In 2014 the OLT commissioned this good practice report to review the grants and fellowships conducted between 2009 and 2014. Encompassing twenty-seven learning and teaching projects and fellowships, the aims of this report include providing universities and academics with an overview of the current state of postgraduate study in Australia and the major influences upon it; a coherent overview of funded projects’ findings and outcomes; and a central point to access good practices, resources and tools in summary form. The objectives of this good practice report are to provide: • A literature review, which contextualises the projects within the Australian and international Higher Education environment, emphasises factors that currently influence postgraduate programs, and highlights challenges and opportunities for the sector. It also explains variations in postgraduate course types and definitions within the Australian Qualification Framework (AQF), and identifies key learning and teaching issues as well as good practices identified in scholarly research and position papers. • A collated overview of the twenty-seven national learning and teaching projects and fellowships on postgraduate coursework and research, including a summary of each project’s aims and objectives, methodologies, outcomes and resources. • A summative index of project characteristics (topics, themes and approaches) and inventory of scholarly research outcomes of the completed projects (publications, reports) as well as resources produced (tools, methods, good practice case studies), and their location (URL Links, references, etc.). • A summary of good practices that have been identified from the literature and the findings of completed projects. • A set of recommendations to address remaining gaps in the field and areas in which further work or development are appropriate. Bringing this work together will help enable university course teams to improve the delivery and development of existing postgraduate courses and to develop new ones, and it will provide academics with an overview of good practices and resources for teaching, supervising and supporting postgraduate students.

Supervising practice: Perspectives on the supervision of creative practice higher degrees by research

PhD supervision is a particularly complex form of pedagogical practice, and nowhere is its complexity more apparent than in new and emergent fields, such as creative practice Higher Degrees by Research (HDRs) where supervisors face the challenges of a unique, uncharted area of research training. While there is an increasing body of literature on postgraduate supervision, and another emerging body of research into what creative practice/practice-led/practice-based research is, so far little attention has been paid to matters associated with research education leadership and pedagogical aspects of supervision in creative practice disciplines.For this reason, this special issue brings together a range of perspectives on the supervision of creative practice PhDs in visual and performing arts, media production, creative writing, and design.

Genetic burden associated with varying degrees of disease severity in endometriosis

Endometriosis is primarily characterized by the presence of tissue resembling endometrium outside the uterine cavity and is usually diagnosed by laparoscopy. The most commonly used classification of disease, the revised American Fertility Society (rAFS) system to grade endometriosis into different stages based on disease severity (I to IV), has been questioned as it does not correlate well with underlying symptoms, posing issues in diagnosis and choice of treatment. Using two independent European genome-wide association (GWA) datasets and top-level classification of the endometriosis cases based on rAFS [minimal or mild (Stage A) and moderate-to-severe (Stage B) disease], we previously showed that Stage B endometriosis has greater contribution of common genetic variation to its aetiology than Stage A disease. Herein, we extend our previous analysis to four endometriosis stages [minimal (Stage I), mild (Stage II), moderate (Stage III) and severe (Stage IV) disease] based on the rAFS classification system and compared the genetic burden across stages. Our results indicate that genetic burden increases from minimal to severe endometriosis. For the minimal disease, genetic factors may contribute to a lesser extent than other disease categories. Mild and moderate endometriosis appeared genetically similar, making it difficult to tease them apart. Consistent with our previous reports, moderate and severe endometriosis showed greater genetic burden than minimal or mild disease. Overall, our results provide new insights into the genetic architecture of endometriosis and further investigation in larger samples may help to understand better the aetiology of varying degrees of endometriosis, enabling improved diagnostic and treatment modalities.

Do bacteria differentiate between degrees of nanoscale surface roughness?

Whereas the employment of nanotechnology in electronics and optics engineering is relatively well established, the use of nanostructured materials in medicine and biology is undoubtedly novel. Certain nanoscale surface phenomena are being exploited to promote or prevent the attachment of living cells. However, as yet, it has not been possible to develop methods that completely prevent cells from attaching to solid surfaces, since the mechanisms by which living cells interact with the nanoscale surface characteristics of these substrates are still poorly understood. Recently, novel and advanced surface characterisation techniques have been developed that allow the precise molecular and atomic scale characterisation of both living cells and the solid surfaces to which they attach. Given this additional capability, it may now be possible to define boundaries, or minimum dimensions, at which a surface feature can exert influence over an attaching living organism.This review explores the current research on the interaction of living cells with both native and nanostructured surfaces, and the role that these surface properties play in the different stages of cell attachment.

Analysis of two degrees of freedom systems through weighted mean square linearization approach

In this paper a study of the free, forced and self-excited vibrations of non-linear, two degrees of freedom systems is reported. The responses are obtained by linearizing the nonlinear equations using the weighted mean square linearization approach. The scope of this approach, in terms of the type of non-linearities the method can tackle, is also discussed.

Decoupling in non-linear systems with two degrees of freedom

The problem of decoupling a class of non-linear two degrees of freedom systems is studied. The coupled non-linear differential equations of motion of the system are shown to be equivalent to a pair of uncoupled equations. This equivalence is established through transformation techniques involving the transformation of both the dependent and independent variables. The sufficient conditions on the form of the non-linearity, for the case wherein the transformed equations are linear, are presented. Several particular cases of interest are also illustrated.

Measurement of shock stand-off distance on a 120 degrees blunt cone model at hypersonic Mach number in Argon

The flow around a 120 degrees blunt cone model with a base radius of 60mm has been visualised at Mach 14.8 and 9.1 using argon as the test gas, at the newly established high speed schlieren facility in the IISc hypersonic shock tunnel HST2. The experimental shock stand off distance around the blunt cone is compared with that obtained using a commercial CFD package. The computed values of shock stand off distance of the blunt cone is found to agree reasonably well with the experimental data.

Diversity and degrees of freedom of cooperative wireless networks

Two key parameters in the outage characterization of a wireless fading network are the diversity and the degrees of freedom (DOF). These two quantities represent the two endpoints of the diversity multiplexing gain tradeoff, In this paper, we present max-flow min-cut type theorems for computing both the diversity and the DOF of arbitrary single-source single-sink networks with nodes possessing multiple antennas. We also show that an amplify-and-forward protocol is sufficient to achieve the same. The DOF characterization is obtained using a conversion to a deterministic wireless network for which the capacity was recently found. This conversion is operational in the sense that a capacity-achieving scheme for the deterministic network can be converted into a DOF-achieving scheme for the fading network. We also show that the diversity result easily extends to multisource multi-sink networks whereas the DOF result extends to a single-source multi-cast network. Along the way, we prove that the zero error capacity of the deterministic network is the same as its c-error capacity.

Electron-Paramagnetic-Res study of LiKSO4 in phase IV below -138 degrees C

A detailed single-crystal EPR study of phase IV of lithium potassium sulphate below -138 degrees C has been carried out using NH3+, which substitutes for K+, as the paramagnetic probe. The spin-Hamiltonian parameters have been evaluated at -140 degrees C and yield an isotropic g=2.0034; (AH)XX=(AH)YY=25.3 G and (AH)ZZ=23.8 G; (AN)XX=8.1 G, (AN)YY=21.2 G and (AN)ZZ=25.9 G. In this phase there are 12 magnetically inequivalent K+ sites and their occurrence is ascribed to the loss of a c glide.

High-Temperature (1023 K to 1273 K 750 degrees C to 1000 degrees C]) Plastic Deformation Behavior of B-Modified Ti-6Al-4V Alloys: Temperature and Strain Rate Effects

A minor addition of B to the Ti-6Al-4V alloy, by similar to 0.1 wt pct, reduces its as-cast prior beta grain size by an order of magnitude, whereas higher B content leads to the presence of in situ formed TiB needles in significant amounts. An experimental investigation into the role played by these microstructural modifications on the high-temperature deformation behavior of Ti-6Al-4V-xB alloys, with x varying between 0 wt pct and 0.55 wt pct, was conducted. Uniaxial compression tests were performed in the temperature range of 1023 K to 1273 K (750 degrees C to 1000 degrees C) and in the strain rate range of 10(-3) to 10(+1) s(-1). True stress-true strain responses of all alloys exhibit flow softening at lower strain rates and oscillations at higher strain rates. The flow softening is aided by the occurrence of dynamic recrystallization through lath globularization in high temperature (1173 K to 1273 K 900 degrees C to 1000 degrees C]) and a lower strain rate (10(-2) to 10(-3) s(-1)) regime. The grain size refinement with the B addition to Ti64, despite being marked, had no significant effect on this. Oscillations in the flow curve at a higher strain rate (10(0) to 10(+1) s(-1)), however, are associated with microstructural instabilities such as bending of laths, breaking of lath boundaries, generation of cavities, and breakage of TiB needles. The presence of TiB needles affected the instability regime. Microstructural evidence suggests that the matrix cavitation is aided by the easy fracture of TiB needles.

Neutron diffraction study of the coupling between spin, lattice, and structural degrees of freedom in 0.8BiFeO(3)-0.2PbTiO(3)

A powder neutron diffraction study was carried out on 0.8BiFeO(3)-0.2PbTiO(3) in the temperature range 27-1000 degrees C. The system exhibits magnetic transition at similar to 300 degrees C and a rhombohedral (R3c)-cubic (Pm3m) ferroelectric phase transition at similar to 650 degrees C. Anomalous variation in the lattice parameters and the octahedral tilt angle is observed across the magnetic transition temperature. In the magnetic phase, the c parameter is contracted and the octahedral tilt angle is slightly increased. The results suggest coupling between the spin, lattice and structural degrees of freedom.
