Speaking of Supervision: A dialogic approach to building higher degree research supervision capacity in the creative arts

Abstract

In the emergent field of creative practice higher degrees by research, first generation supervisors have developed new models of supervision for an unprecedented form of research, which combines creative practice and a written thesis. In a national research project, entitled ‘Effective supervision of creative practice higher research degrees’, we set out to capture and share early supervisors’ insights, strategies and approaches to supporting their creative practice PhD students. From the insights we gained during the early interview process, we expanded our research methods in line with a distributed leadership model and developed a dialogic framework. This led us to unanticipated conclusions and unexpected recommendations. In this study, we primarily draw on philosopher and literary theorist Mikhail Bakhtin’s dialogics to explain how giving precedence to the voices of supervisors not only facilitated the articulation of dispersed tacit knowledge, but also led to other discoveries. These include the nature of supervisors’ resistance to prescribed models, policies and central academic development programmes; the importance of polyvocality and responsive dialogue in enabling continued innovation in the field; the benefits to supervisors of reflecting, discussing and sharing practices with colleagues; and the value of distributed leadership and dialogue to academic development and supervision capacity building in research education.     

Burdens too difficult to carry? A case study of three academically able Indigenous Australian Masters students who had to withdraw

Previous research into attrition rates of Indigenous Australian Higher Degree by Research (HDR) candidates has focused on institutional barriers, highlighting cultural disparities. This case study of three academically able candidates who withdrew before completion from an institution designed to meet the needs of Indigenous students describes their path into the award and non-academic factors over the span of their education that impacted on their performance, then draws upon studies of resilience to propose that the psycho-social environments in which they had to operate were complex and burdensome. It proposes that institutions that enroll Indigenous Australian HDR candidates cannot ignore these environments and more appropriate support strategies should be employed.

Thermal comfort evaluation of people in subway station

We analyzed the characteristics of subway station environment and the change of thermal comfort for passengers when they are in and out of the station. The dynamic thermal comfort evaluation model RWI (relative warmth index) and HDR (heat deficit rate) were built on the distinguishing features of public area in subway station. Taking one representative subway station in Nanjing as the research object, the thermal comfort conditions in different seasons and different parts were studied by field tests, questionnaires and model-evaluating. The calculated RWI shows that although the thermal comfort in Nanjing metro is relatively acceptable, ideal thermal comfort has not been achieved. And it is found that associated with predicted mean vote (PMV), using RWI can evaluate the thermal comfort more precisely.     

一种新的HDR无线网络吞吐率容量计算方法

基于一种新的非参数方法计算了HDR (high data rate)无线网络的吞吐率容量区域. 首先把HDR吞吐率容量区域的计算问题转化为一个不带参数的数学优化问题, 然后通过贪婪算法求解得到该优化问题的解, 从而最终给出了HDR吞吐率容量区域的非参数解析刻划. 与传统的参数化方法的庞大计算量相比, 该方法的计算复杂度降低很多, 最多只需要计算N(M2-M 1)N-1个线性约束即可, 其中N为用户数, M为系统支持速率数. 数值计算例子验证了这种非参数方法的正确性.     

游戏动画场景中HDR的意义

随着游戏产业的迅猛发展,个人电脑性能的不断攀升,游戏需求已经从18岁以前的青少年儿童普及到各个年龄层次的人群,游戏产业已经进入一个飞速发展的阶段。艺术类专业的高校对多媒体动画专业的投入力度也大大加强。但是我们清楚的看到,游戏无论从概念设计,场景细节,色彩画面,以及各个环境中灯光的渲染和高精度的材质贴图都具有相当大的局限性。文章具体针对游戏动画现状,提出针对使用HDR高精度场景渲染以及各环境下灯光布置的重要意义。     

A high-efficiency and versatile CRISPR/Cas9-mediated HDR-based biallelic editing system

Clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 nuclease (Cas9), the third-generation genome editing tool, has been favored because of its high efficiency and clear system composition. In this technology, the introduced double-strand breaks (DSBs) are mainly repaired by non-homologous end joining (NHEJ) or homology-directed repair (HDR) pathways. The high-fidelity HDR pathway is used for genome modification, which can introduce artificially controllable insertions, deletions, or substitutions carried by the donor templates. Although high-level knock-out can be easily achieved by NHEJ, accurate HDR-mediated knock-in remains a technical challenge. In most circumstances, although both alleles are broken by endonucleases, only one can be repaired by HDR, and the other one is usually recombined by NHEJ. For gene function studies or disease model establishment, biallelic editing to generate homozygous cell lines and homozygotes is needed to ensure consistent phenotypes. Thus, there is an urgent need for an efficient biallelic editing system. Here, we developed three pairs of integrated selection systems, where each of the two selection cassettes contained one drug-screening gene and one fluorescent marker. Flanked by homologous arms containing the mutated sequences, the selection cassettes were integrated into the target site, mediated by CRISPR/Cas9-induced HDR. Positively targeted cell clones were massively enriched by fluorescent microscopy after screening for drug resistance. We tested this novel method on the amyloid precursor protein (APP) and presenilin 1 (PSEN1) loci and demonstrated up to 82.0% biallelic editing efficiency after optimization. Our results indicate that this strategy can provide a new efficient approach for biallelic editing and lay a foundation for establishment of an easier and more efficient disease model.
