In this talk, I will present the results of several studies examining qualitative and quantitative empirical research articles from applied linguistics. The studies use both corpus-based analyses and rhetorical genre analysis to describe similarities and differences across the two paradigms. Each of the studies draws on a corpus of published studies from journals that regularly publish both quantitative and qualitative articles on the topic of language learning and teaching.
I first describe the compilation of the corpus, which currently includes 863 studies from 2013 to 2023, and explain some of the challenges involved in using copyrighted materials in a time of calls for open science. Next, I explain the rationale for comparing qualitative and quantitative research in a subfield of applied linguistics. Specifically, I talk about the challenges of a field in which there appears to be a widening divide in the nature of research in the two paradigms along with unsubstantiated claims in research manuals characterizing the two paradigms.
The bulk of the talk will focus on my and my collaborators’ research agenda using our created corpus. Two of the studies focus on the role of theory in the empirical studies. The first study used a corpus-based analysis of the frequency and collocations of the lemma theor- while the second used rhetorical move analysis to show how theory was used in structuring literature reviews. Both studies revealed differences in the role of theory in the two paradigms that show how language choice and rhetorical moves reflect their epistemologies. The third study focused on citation use and revealed some differences, but more similarities. Finally, we have two studies in progress examining article structure and lexical bundles. Taken together, both studies show that quantitative research is more structured and predictable. I end by suggesting possible extensions of our research using qualitative methods.
The final part of this talk will explain the relevance of this research to both teaching academic writing and to the field of applied linguistics. With regard to teaching writing, I will give specific examples of how the various analyses used in the five studies can be transferred to heterogeneous writing classes to help students explore conventions in their own fields. Second, I explain how the studies suggest a widening gap between the two paradigms and how this gap presents problems for graduate programs, journals, and professional organizations, all of which, I argue, need to be more sensitive to acknowledging research in both paradigms.

A rapidly expanding research area involves the development of routes to shape programmable three-dimensional (3D) structures with feature sizes in the mesoscopic range (that is, between tens of nanometres and hundreds of micrometres). A goal is to establish methods to control the properties of materials systems and the function of devices, through not only static architectures, but also morphable structures and shape-shifting processes. Soft matter equipped with responsive components can switch between designed shapes, but cannot support the types of dynamic morphing capabilities needed to reproduce continuous shape-shifting processes of interest for many applications. Challenges lie in the establishment of 3D assembly/fabrication techniques compatible with wide classes of materials and 3D geometries, and schemes to program target shapes after fabrication.
In this talk, Prof. HUANG Yonggang will introduce a mechanics-guided assembly approach that exploits controlled buckling for constructing complex 3D micro/nanostructures from patterned two-dimensional (2D) micro/nanoscale precursors that can be easily formed using established semiconductor technologies. This approach applies to a very broad set of materials (e.g., semiconductors, polymers, metals, and ceramics) and even their heterogeneous integration, over a wide range of length scales (e.g., from 100 nm to 10 cm). To allow realisation of 3D mesostructures that are capable of qualitative shape reconfiguration, Prof. HUANG devises a loading-path controlled strategy that relies on elastomer platforms deformed in different time sequences to elastically alter the 3D geometries of supported mesostructures via nonlinear buckling. Prof. HUANG will also introduce a recent work on shape programmable soft surface, constructed from a matrix of filamentary metal traces, driven by programmable, distributed electromagnetic forces that follow from the passage of electrical currents in the presence of a static magnetic field. Under the guidance of a mechanics model-based strategy to solve the inverse problem, the surface can morph into a wide range of 3D target shapes and shape-shifting processes. The compatibility of these approaches with the state-of-the-art fabrication/processing techniques, along with the versatile capabilities, allow transformation of diverse existing 2D microsystems into complex configurations, providing unusual design options in the development of novel functional devices.

The seminar commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation) of PolyU. This was followed by Prof. Leng’s presentation. He first provided a brief background about shape memory polymers (SMP), pointing out that these smart materials can reversibly change between permanent and temporary shapes in response to changes in external stimuli such as temperature. Next, he gave an overview of the researchers from different scientific research institutions and universities around the world who specialise in SMP research, and the types of SMP materials that HIT researchers focus on. He said that SMP are hard to actuate and their recovery strength and speed are low, and so relevant solutions to these challenges are important for the development of SMP composites (SMPC). Prof. Leng then gave examples demonstrating how SMPC can be prepared through actuation methods involving different stimuli such as heat, electricity, magnetism, radio frequency, solution/water, light, etc. He mentioned that SMPC can be used to prepare various structures for aerospace, smart manufacturing, photoelectric applications, microelectromechanical systems applications, and smart clothing. After that, Prof. Leng introduced 4D printing, a novel additive manufacturing process for producing printed objects that can adaptively change their configurations/properties in response to external stimuli. He mentioned that 4D printing is important for producing a range of SMPC-based materials for biomedical applications. To conclude, Prof. Leng said that SMP research is a fast-growing emerging research field. He anticipated that shape memory smart structures incorporated with sensors, actuators, and controllers, would be widely used in aerospace, civil aviation, automotive, energy and daily life.
