Higher Education Strategy in Responding to the Generative AI Revolution Decolonising the Standard Response and Action Planning Protocols
Background: The Generative Artifical Intelligence (AI) revolution is here, and the availability of resources such as ChatGPT has triggered rapid responses, actions, and strategy to address the implications this has on education in the United Kingdom (UK). ChatGPT and other Generative AI provisions are viewed as both problematic and beneficial by Higher Education Institutes (HEI’s). Alongside HEI’s, Higher Education England (HEE) Technology Enhanced Learning (TEL) forums are just 1 of many additional UK national groups prioritising the discussion, Continual Professional Development (CPD), and strategical approaches to analysing Generative AI, in determining how it should be addressed in education and practice.
In terms of standard practice at London South Bank University (LSBU), the planning of projects and research to explore new technology lies predominantly with those deemed as the most “skilled”, “technical” or “aware” of the technology. People who are in specific roles within the institute are expected to “lead” on strategy, and this onus of responsibility often remains with them throughout the process from start to finish. Recognising the imbalance of power and the benefits of privilege this practice could create, a decision was made to explore and propose re-design of the current protocols in place at LSBU.
Aim: Demonstrate the inclusion of a Decolonising step at the earliest designing stage of the project, to influence a practice change in how a HEI could respond to major items affecting education and any subsequent action-planning or project designing.
Method: 3 academic members of staff, and 3 undergraduate students, of Black, Asian, African or Minority ethnicity, will be recruited. Individual and group sessions will be conducted using Microsoft Teams. Sessions will involve the participants leading on the discussion and development of the project proposal and associated documents being used in the larger study. This will occur between 19th May – 1st June 2023, after which the project proposal will be registered with the LSBU research ethics committee and internal registration system (Haplo).
The Decolonising strategy and effects will be appraised by an independent investigator making objective comparisons to a version of the project protocol originally written by the Principal Investigator as a lone researcher. Themes and major highlights to demonstrate these comparisons, will be presented as the outcome for this project. All results and recommendations will be ready for presentation by no later than 15th June 2023.
Expected Outcomes: Recommendations based on the outcome could feasibly affect changes in the future strategy for responding to major items requiring adaptation and evolution in education/practices, and potential other general and/or specific response/action-planning protocols, at London South Bank University.
Additional information: This project forms part of a larger LSBU Generative AI project to explore a potential solution to the issues surrounding Generative AI in Higher Education
Actividad antibacteriana y antioxidante de los extractos de Piper cubeba (Piperaceae)
Piper cubeba L. (Piperaceae), commonly known as ‘cubeb’, is native to Indonesia, and also found in many other countriesof the South-East Asia, and in some African countries. This plant has been used as a popular food additive, andin folklore medicine to treat various ailments, particularly bacterial infections. The n-hexane, dichloromethane (DCM)and methanol (MeOH) extracts of the dried berries (fruit) of this plant were assessed for their antioxidant (free radicalscavenging) and antibacterial activities using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and the micro titre basedantimicrobial assay incorporating resazurin as an indicator of cell growth, respectively. While all extracts showed antioxidantactivity in the qualitative assay, the most prominent antioxidant activity was observed with the MeOH extract inthe quantitative assay with a RC50 value of 2.71 x 10-1 mg/mL. The antioxidant potency of the DCM extract was about3 fold less (RC50 = 6.50 x 10-1 mg/mL) than that of the MeOH extract. None of the extracts showed any antibacterialproperty against Bacillus subtilis, Escherichia coli, and ampicillin resistant Escherichia coli. While both the n-hexaneand the DCM extracts inhibited the growth of Bacillus cereus, Pseudomonas aeruginosa and Staphylococcus aureus, theMeOH extract was active only against B. cereus and P. aeruginosa. The most potent antibacterial activity was displayedby the n-hexane extract against B. cereus with an MIC value of 1.56 mg/mL. All antibacterial activities of the extractswere found to be bacteriostatic rather than bactericidal.Piper cubeba L.

Can People with Chronic Neck Pain Recognize Their Own Digital Pain Drawing?
Background: Although the reliability of pain drawings (PDs) has been confirmed in people with chronic pain, there is a lack of evidence about the validity of the PD, that is, does the PD accurately represent the pain experience of the patient?
Objectives: We investigate whether people with chronic neck pain (CNP) can recognize their own PD to support the validity of the PD in reporting the experience of pain. Moreover, we
examined the association between their ability to recognize their own PD with their levels of pain intensity and disability and extent of psychosocial and somatic features.
Study Design: Experimental.
Setting: University Laboratory.
Methods: Individuals with CNP completed their PD on a digital body chart, which was then automatically modified with specific dimensions using a novel software, providing an objective range of distortion and eliminating errors, which could potentially occur in manually controlled visual-subjective based methods. Following a 10-minute break listening to music, a series of 20 PDs were presented to each patient in a random order, with only 2 being their original PD. For each PD, the patients rated its likeliness to their own original PD on a scale from 0 to 100, with 100 representing “this is my pain.”
Results: Overall, the patients rated their original PD with a median score of 92% similarity, followed by 91.8% and 89.5% similarity when presented with a PD scaled down to 75%
and scaled up by 150% of the original size, respectively; these scores were not significantly different to the ratings given for their original PD. The PD with horizontal translation by 40 pixels (8%) and vertical translation by 70 pixels (12.8%) were rated as the most dissimilar to their original PD; these scores were significantly different to their original PD scores. The Spearman correlation coefficient revealed a significant negative association between their ability to recognize their original PD and their Modified Somatic Perceptions Questionnaire scores.
Limitations: The patients in the study presented with relatively mild CNP, and the results may not be generalized to those with more severe symptoms.
Conclusions: People with CNP are generally able to identify their own PD but that their ability to recognize their original PD is negatively correlated with the extent of somatic awareness
A meta-analysis and systematic review of changes in joint position sense and static standing balance in patients with whiplash-associated disorder
Objective
To synthesise and analyse the current evidence regarding changes in joint position sense (JPS) and standing balance in people with whiplash-associated disorder (WAD) taking the presence or absence of dizziness into account.
Data sources
PubMed, CINAHL Plus, Web of Science, Embase, MEDLINE and APA PsycINFO were searched by two independent reviewers from inception until August 2020 and reference lists of all included studies were also reviewed.
Study selection
Only cross-sectional studies that measured JPS and/or standing balance between people with WAD vs. healthy controls (HC) or people with WAD complaining of dizziness (WADD) vs. those not complaining of dizziness (WADND) were selected.
Data extraction
Relevant data were extracted using specific checklists and quality assessment was performed using Downs and Black Scale (modified version).
Data synthesis
Twenty-six studies were included. For JPS, data were synthesized for absolute error in the primary plane of movement for separate movement directions. For standing balance, data were synthesized for traditional time- and frequency domain sway parameters considering the conditions of eyes open (EO) and eyes closed (EC) separately. For meta-analysis, reduced JPS was observed in people with WAD compared to HC when the head was repositioned to a neutral head position (NHP) from rotation (standardised mean difference [SMD] = 0.43 [95%: 0.24–0.62]) and extension (0.33 [95%CI: 0.08–0.58]) or when the head was moved toward 50° rotation from a NHP (0.50 [0.05–0.96]). Similarly, people with WADD had reduced JPS compared to people with WADND when the head was repositioned to a NHP from rotation (0.52 [0.22–0.82]). Larger sway velocity and amplitude was found in people with WAD compared to HC for both EO (0.62 [0.37–0.88] and 0.78 [0.56–0.99], respectively) and EC (0.69 [0.46–0.91] and 0.80 [0.58–1.02]) conditions.
Conclusion
The observed changes of JPS and standing balance confirms deficits in sensorimotor control in people with WAD and especially in those with dizziness

INFLUENCE OF FLOW REGIMES ON TEMPERATURE HETEROGENEITIES WITHIN A SCRAPED SURFACE HEAT EXCHANGER
Efficacy of Standardized Extract of Bacopa monnieri (Bacognize®) on Cognitive Functions of Medical Students: A Six-Week, Randomized Placebo-Controlled Trial
Rationale. Bacopa monnieri, popularly known as Brahmi, has been traditionally used in Ayurveda since ages for its memory enhancing properties. However, data on placebo-controlled trial of Bacopa monnieri on intellectual sample is scarce. Hence this study was planned to evaluate the effect of Bacopa monnieri on memory of medical students for six weeks. Objective. To evaluate the efficacy of Bacopa monnieri on memory of medical students with six weeks’ administration. Method and Material. This was a randomized double blind placebo-controlled noncrossover, parallel trial. Sixty medical students of either gender from second year of medical school, third term, regular batch, were enrolled from Government Medical College, Nagpur, India. Baseline biochemical and memory tests were done. The participants were randomly divided in two groups to receive either 150 mg of standardized extract of Bacopa monnieri (Bacognize) or matching placebo twice daily for six weeks. All baseline investigations were repeated at the end of the trial. Students were followed up for 15 days after the intervention. Results. Statistically significant improvement was seen in the tests relating to the cognitive functions with use of Bacopa monnieri. Blood biochemistry also showed a significant increase in serum calcium levels (still within normal range)
