Embracing Change: Navigating Curriculum and Assessment for AI Literacy in Higher Education Writing
Get PDFFrom Board to Interactive Hub: Integrating AI into Online Mathematics Courses
Get PDFAcross disciplines, educators employ discussion boards to create an opportunity for students to interact with each other and the content. In my experience teaching first and second year mathematics online courses, creating suitable questions for this format, while also providing meaningful insights for students and instructors alike, has been a challenge. I wanted to use discussion boards to reinforce content. However, I also wanted to take advantage of their underlying format. That is, the opportunity they lend exploring relevant and current real-world applications, as well as evaluation and critical thinking - ideas at the core of math curricula. What I found is that integrating artificial intelligence into the discussions presents new avenues to reflect on future directions of math in particular majors, relevant current applications for students, and the importance of data and information literacy. Furthermore, this integration allows students the opportunity to critically evaluate information from online algorithms, including their own engagements with various forms of AI. The inclusion of AI has made the use of the discussion board far more valuable and interesting in these courses.  
The role of text alignment on response speed and accuracy when reading Chinese/English bilingual traffic signs
No full textThis paper discusses the role of text alignment on the speed and accuracy of navigational responses for participants who read English but not Chinese when presented with bilingual Chinese/English traffic signs. Two text alignment conditions (centered and ragged right settings) are tested in relation to two independent variables: sign complexity and vertical separating spacing between scripts in a pair of studies. Video materials are used to provide a safe way to simulate how and where road signs may appear in a driving scenario, while efficiently testing many variations. The results suggest that left alignment improves speed and accuracy in complex, multi-direction signs with narrower vertical separating spacing, whereas central alignment may be beneficial for simpler signs with single direction indications. These findings highlight the value of including alignment specification in guidance for bilingual signage, especially when accounting for sign complexity. However, it would be important to conduct further studies using methods with a higher ecological validity and a broader range of participants before robust recommendations can be devised

A Novel Laboratory Method for the Extraction of Black Wattle (Acacia Mearnsii De Wild.) Bark Constituents
No full textTannins are the major extractable component of black wattle (Acacia Mearnsii de Wild) bark. In a wattle factory, extracted tannin levels are one of several quality parameters (Extraction efficiency and insoluble content are some of the other parameters) that are monitored, typically using a modified Soxhlet/ reflux extraction method. However, this method is slow and laborious, and the extracted product is unsuitable for tannin color analysis, which is another important product quality parameter. A new method was then developed, aiming to measure both the conventional bark parameters as well as the color of the extract solution, and increase sample throughput. The effect of oven-drying versus freeze-drying was compared as a method of moisture removal for tannin color preservation prior to extraction. Sample filtration methods, extraction times, and chemical additives were also tested, compared, and optimised as necessary. Suitably processed bark samples were subjected to four extraction methods, i.e., Soxhlet, cold water, pressure cooker, and autoclave extractions. Extract properties were analysed using the standard Society for Leather Technologists and Chemists (SLTC) methods. Freeze- drying was shown to arrest color development in the bark. Deionisedwater was the best extractant tested, although the addition of ethylenediaminetetraacetic acid (EDTA) enhanced the color of the extracts. The autoclave extraction method, involving two extractions and centrifugation, was found to be the most practical and effectivefor wattle bark. It minimizes color change, reduces sample analysis variability, and allows for high sample throughput. This method is valuable for future research on wattle bark properties and for routine quality analysis in wattle extract factories
Research on the Innovative Mode of Leather Fusion Design
No full textThe fusion design represents an innovative approach to extending leather materials’ application value and scope. This study first analyzes the material properties, aesthetic characteristics, and decorative techniques of leather and explores fusion design pathways from four perspectives with different materials, cultures, craftsmanship, and forms. We propose four principles for the innovative design of leather material fusion, including “Integration of tradition and modernity,” “Balance between material and process,” “Resonance of emotion and connotation,” and “Unity of aesthetics and practicality.” A novel fusion design methodology, comprising “representational design” and “metaphoric design,” is subsequently proposed. Finally, an application model for innovative leather fusion design is constructed. A leather installation artwork is employed to validate the feasibility of the theoretical model. This study enhances the theoretical foundation of leather fusion innovation design and provides new practical pathways for its application
Vegetable Tannins used in Leather Industry and Extraction Methods
No full textLeather production includes a series of process steps in which various chemicals are used. Tanning is the stage of converting rawhide into finished leather that is the main process of leather production. In this process, vegetable substances, various metal salts, aldehydes, polymers, resins, etc. are used by the reaction with collagen of skin or hide proteins. The vegetable tanning method is one of the most established and customary techniques among them and this technique makes use of compounds known as tannins that are derived from different plants. The polyphenols contained in the tannins in the structures of the plants have the ability to tan the leather. Tannins are found in various parts of plants such as wood, bark, leaves, roots, fruits and thuja. Although some plants were used directly by grinding in the past, extraction is mostly applied to obtain tannins from plants. In this study, the plants commonly used in leather tanning and the extraction methods applied to obtain tannins from these plants are described. The mechanisms, advantages and disadvantages of these methods are discussed. This research will enable the explanation of guiding techniques for the creation of substitute vegetable tanning agents as well as the emergence of ideal conditions in the manufacturing of already available vegetable tanning agents
