Incorporating Generative AI to Promote Inquiry-Based Learning: Comparing Elicit AI Research Assistant to PubMed and CINAHL Complete.

Generative artificial intelligence (GenAI) is transforming education, and faculty can either incorporate GenAI in intentional course design to promote inquiry-based learning (IBL) or resist its use. This study identified an effective strategy to intentionally integrate GenAI in the course design to promote IBL. A descriptive study design was used for graduate nursing students to compare the effectiveness of a GenAI literature search tool, Elicit: The AI Research Assistant, to PubMed and CINAHL. A two-phase framework was utilized to organize complex information and justify a preference. A rubric was designed to promote and assess critical thinking through IBL in educating graduate nursing students on information literacy and structuring a literature search. Discovering a relationship between the search tools, students identified the strengths (pros) and weaknesses (cons) of each tool and determined which tool was more effective in terms of accuracy, relevance and efficiency.

Use of Stated Preference Methods in HIV Treatment and Prevention Research in the United States: A Systematic Review.

Stated preference (SP) methods are increasingly being applied to HIV-related research and continuously provide researchers with health utility scores of select healthcare products or services that populations consider important. Following PRISMA guidelines, we sought to understand how SP methods have been applied in HIV-related research. We conducted a systematic review to identify studies meeting the following criteria: SP method is clearly stated, conducted in the United States, was published between 01/01/2012 and 02/12/2022, and included adults aged 18 and over. Study design and SP method application were also examined. We identified six SP methods (e.g., Conjoint Analysis, Discrete Choice Experiment) across 18 studies, which were categorized into one of two groups: HIV prevention and HIV treatment-care. Categories of attributes used in SP methods largely focused on: administration, physical/health effects, financial, location, access, and external influences. SP methods are innovative tools capable of informing researchers on what populations consider most beneficial when deciding on treatment, care, or prevention options for HIV.

[Effects of methyl jasmonate on accumulation of furanocoumarins in Changium smyrnioides and its suspension cells].

Changium smyrnioides is an endangered and endemic medicinal herb in China which contains rich furanocoumarins. Bergaptol, bergapten and xanthotoxin are natural furanocoumarins in Ch. smyrnioides, among which bergaptol is mainly contained in in vitro cultures while the latter ones distribute in all organs and cultures of the plant. In this study, methyl jasmonate was used to elicit furanocoumarins in both cultivated plant and suspension cells. The accumulations of biomass and 3 furanocoumarins as well as the activity of cell, phenylalanine ammonia-lyase and antioxidase were detected. The results showed that methyl jasmonate induced the biosynthesis of furanocoumarins markedly and suspension cells from petiole produced more furanocoumarins than those from leaf. In the case of suspension cells, the concentration at 100 µmol•L⁻¹ triggered the highest yield of furanocoumarins and the 10th day of the culture period was the proper time for treatment. After 4 days the yields of bergaptol, bergapten and xanthotoxin in suspension cells from petiole were enhanced to 2.83,14.04,0.62 mg•L⁻¹ respectively. The biomass and viability of treated suspension cells decreased. At the same time, the activity of antioxidase increased, which indicated that methyl jasmonate induced cell defense. In both in vivo and in vitro conditions, cells from petiole seemed to be more sensitive to methyl jasmonate treatment compared to those from leaf. Bergaptol and xanthotoxin mainly accumulated in medium and cell respectively. Bergapten was detected in both cell and medium. The elicitation treatment only enormously affected the yields but did not significantly involve the distributions of 3 furanocoumarins. This is the first systematic study focusing on the elicitation effects of methyl jasmonate and a series of changes which lead to the increase of furanocoumarins in Ch. smyrnioides cell suspension cultures. Methyl jasmonate appears to be an effective elicitor in the research and further efforts should be made to reveal the mechanism in detail.

Reference Hallucination Score for Medical Artificial Intelligence Chatbots: Development and Usability Study.

BACKGROUND: Artificial intelligence (AI) chatbots have recently gained use in medical practice by health care practitioners. Interestingly, the output of these AI chatbots was found to have varying degrees of hallucination in content and references. Such hallucinations generate doubts about their output and their implementation. OBJECTIVE: The aim of our study was to propose a reference hallucination score (RHS) to evaluate the authenticity of AI chatbots' citations. METHODS: Six AI chatbots were challenged with the same 10 medical prompts, requesting 10 references per prompt. The RHS is composed of 6 bibliographic items and the reference's relevance to prompts' keywords. RHS was calculated for each reference, prompt, and type of prompt (basic vs complex). The average RHS was calculated for each AI chatbot and compared across the different types of prompts and AI chatbots. RESULTS: Bard failed to generate any references. ChatGPT 3.5 and Bing generated the highest RHS (score=11), while Elicit and SciSpace generated the lowest RHS (score=1), and Perplexity generated a middle RHS (score=7). The highest degree of hallucination was observed for reference relevancy to the prompt keywords (308/500, 61.6%), while the lowest was for reference titles (169/500, 33.8%). ChatGPT and Bing had comparable RHS (ß coefficient=-0.069; P=.32), while Perplexity had significantly lower RHS than ChatGPT (ß coefficient=-0.345; P<.001). AI chatbots generally had significantly higher RHS when prompted with scenarios or complex format prompts (ß coefficient=0.486; P<.001). CONCLUSIONS: The variation in RHS underscores the necessity for a robust reference evaluation tool to improve the authenticity of AI chatbots. Further, the variations highlight the importance of verifying their output and citations. Elicit and SciSpace had negligible hallucination, while ChatGPT and Bing had critical hallucination levels. The proposed AI chatbots' RHS could contribute to ongoing efforts to enhance AI's general reliability in medical research.

Assessing Acute Responses to Exercises Performed Within and at the Upper Boundary of Severe Exercise Domain.

Purpose: The highest work-rate that provides maximal oxygen uptake (V˙O2max) may be one of the best exercise stimuli to yield both V˙O2max and lactate accumulation. The aim of this study was to analyze physiological and metabolic acute responses of an exercise modality performed at the upper boundary of the severe exercise domain, and compare those responses with exercise modalities applied within the severe exercise domain. Method: Ten trained male cyclists participated in this study. The V˙O2max, corresponding power output (POVO2max), and the highest work-rate that provides the V˙O2max (IHIGH) were determined by constant work-rate exercises. Cyclists performed three high-intensity interval training (HIIT) strategies as follows; HIIT-1: 4-6 × 3-min at 95% of POVO2max with 1:1 (workout/rest ratio); HIIT-2: 16-18 × 1-min at 105% of POVO2max with 1:1; HIIT-3: 4-7 × 1-2-min at the IHIGH with 1:2. Capillary blood samples were analyzed before, immediately after HIIT sessions, and at the first, third, and fifth minutes of recovery periods. Lactate difference between the highest lactate response and resting status was considered as the peak lactate response for each HIIT modality. Results: Time spent at V˙O2max was greater at HIIT-1 and HIIT-3 (272 ± 127 and 208 ± 111 seconds, respectively; p = 0.155; effect size = 0.43) when compared to the HIIT-2 (~26 seconds; p < 0.001), while there was a greater lactate accumulation at HIIT-3 (~16 mmol·L-1) when compared to HIIT-1 and HIIT-2 (12 and 14 mmol·L-1, respectively; p < 0.001). Conclusions: In conclusion, HIIT-3 performed at IHIGH was successful to provide time spent at V˙O2max with a greater lactate accumulation in a single session.

Effects of mobile-supervised question-driven collaborative dialogues on EFL learners' communication strategy use and academic oral English performance.

This study investigated the effects of mobile-supervised question-driven collaborative dialogues (QDCDs) on reducing lower-intermediate-level English as a foreign language (EFL) participants' tendency of their first language (L1) use in academic collaborative dialogues and on improving their academic foreign language (L2) oral performance. Throughout a whole semester, one group (n = 20) was involved in a mobile-supervised QDCDs intervention and a control group (n = 26) was involved in QDCDs with no supervision. Three semi-open-ended and three closed-ended academic questions were used to elicit pre-and post-study oral performance data from the participants. Independent-samples t-tests showed that after the intervention, the mobile-supervised group outperformed its control counterpart in a statistically significant manner in terms of Non-repeated L2 word production (NRW), T-unit count (TC), and Mean Length of Run after pruning (MLRP). The intervention group also significantly reduced their dependence on their L1-based speaker compensatory communication strategies (SC-CSs) in QDCDs. These results suggest that the intervention group outperformed the control group in their L2 academic oral performance and their language use tendency moves toward the L2 during QDCD. Based on the findings, we conclude that, even though L1 oral output may temporally enhance the quality of lower-intermediate-level EFL learners' tasks, it may inhibit their academic oral proficiency development in the long run. Methods for fragmental bilingual oral output analysis are introduced. Pedagogical implications of the findings for MALL are also discussed.

Potential vestibular pathway impairment in children with recurrent vertigo: An investigation through air-conducted sound and galvanic vestibular stimulation-triggered vestibular evoked myogenic potentials.

Objective: This study aims to investigate the potential vestibular pathway impairment through vestibular evoked myogenic potentials (VEMPs) and to explore the pathophysiological significance of these instrument-based findings in children with recurrent vertigo. Materials and methods: The clinical data of 21 children (mean age 4.67 ± 1.39 years) diagnosed as RVC who met the inclusion criteria of the Bárány Society and 29 healthy children (mean age 4.83 ± 1.34 years) enrolled as the control group from February 2021 to December 2021 were collected and analyzed retrospectively. All the subjects underwent both cervical VEMP (cVEMP) and ocular VEMP (oVEMP) triggered by air-conducted sound (ACS) and galvanic vestibular stimulation (GVS), respectively. The elicit rate, latency, and amplitude asymmetry ratio (AAR) of ACS-cVEMP, ACS-oVEMP, GVS-cVEMP, and GVS-oVEMP were analyzed. Results: (1) The elicit rates of ACS-cVEMP and ACS-oVEMP were similar in the two groups (P > 0.05), as well as GVS-cVEMP and GVS-oVEMP (P > 0.05). (2) P1 and N1 latencies of ACS-cVEMP and GVS-cVEMP in the RVC group were longer than those in the control group (P < 0.05). (3) The N1 latency of ACS-oVEMP in the RVC group was shorter than that in the control group (P < 0.05), while there was no significant difference in the P1 latency of ACS-oVEMP (P > 0.05). The N1 and P1 latencies of GVS-oVEMP were not significantly different (P > 0.05). (4) There was no statistical difference in the AAR of ACS-cVEMP and GVS-cVEMP. Although there was an increased AAR of ACS-oVEMP in the RVC group (P < 0.05), the AAR was within the normal range. However, no statistical difference was found in the AAR of GVS-oVEMP in the two groups (P > 0.05). Conclusion: The latencies of ACS-cVEMP and GVS-cVEMP in children with recurrent vertigo were significantly prolonged compared with those in healthy children, and there was no difference in elicit rates of ACS-cVEMP and GVS-cVEMP, suggesting that there might be potential impairment in the inferior vestibular nerve and the subsequent nerve conduction pathway in RVC.

Hybrid Methodology to Improve Health Status Utility Values Derivation Using EQ-5D-5L and Advanced Multi-Criteria Techniques.

This paper presented a new approach to the calculation of quality-adjusted life years (QALY) based on multi-criteria decision-making (MCDM) methods and using the EQ-5D-5L questionnaire. The health status utility values were calculated through a hybrid methodology. We combined the analytic hierarchy process (AHP), the AHP with a D-number extended fuzzy preference relation (D-AHP), the fuzzy analytic hierarchy process (F-AHP), and the technique for order preference by similarity to the ideal solution (TOPSIS) to obtain individual and aggregated utility values. The preference data were elicited using a sample of individuals from a Colombian university. In all tested methods, the ordinal preferences were consistent, and the weights were compared using the Euclidean distance criterion (EDC). We identified F-AHP-TOPSIS as the optimal method; its benefits were associated with modeling the response options of the EQ-5D in linguistic terms, it gave the best approximation to the initial preferences according to EDC, and it could be used as an alternative to the known prioritization method. This hybrid methodology was particularly useful in certain medical decisions concerned with understanding how a specific person values his or her current health or possible health outcomes from different interventions in small population samples and studies carried out in low- and middle-low-income countries.

Multiple qualitative procedures to elicit reverse culture shock experience.

This study elaborates the research design and methodology to investigate the reverse culture shock (RCS) experience of young Thai tourists in the tourism field. Taking the worldview position of relative ontology and interpretivist/constructivist paradigms, this paper employs qualitative design using multiple research methods, namely, essay writing, graph plotting and semi-structured interview. Essay writing and graph plotting are initially used as pre-interview activities as part of the memory recall procedures. This stage is important because it helps curtail memory distortion and enrich insight into the participant's past RCS experience. The semi-structured interview with young Thai tourists is subsequently conducted to elicit individual perceptual and emotional experiences and coping mechanism after they returned home. The three research methods complement one another to draw out rich travellers' experience in the tourism study and can be beneficial to the extended disciplines of social science and psychology. Advantages of this article include: •Practical and feasible processes for a qualitative study in social science and psychology, particularly when recall of memory is involved.•The ability to gain enriched information of experience.•The ability to elicit emotional aspects from the study of experience through graph plotting.

Neuro-muscular function in the wobbler murine model of primary motor neuronopathy.

The wobbler mouse represents a model for neurodegenerative disease affecting motor neurons. This study explored the importance of fiber type specific changes for the contractile dysfunction of soleus and extensor digitorum longus (EDL) muscles from wobbler mice using a specific inhibitor of force generation by the type II myosin protein. Generally, wobbler condition was associated with ~50% reductions in muscle mass and contractile capacity in both muscles. In soleus, an increase in the relative abundance of type I myosin protein was observed. Since, however, only ~40% of the fibers containing type I myosin had functional innervation whereas almost all fibers containing type II myosin were innervated, the shift toward type I myosin was without significance for the in vivo contractile phenotype. Soleus muscles from wobbler mice were further characterized by a 2-fold increase in the width of the twitches, which was associated with a reduction in the excitation frequency necessary to elicit tetanic contractions. Since the SR Ca(2+) ATPase in wobbler soleus was reduced from 22 ± 5 to 10 ± 2 nmol/g muscle tissue (P=0.0006), the increase in twitch width was most likely caused by delayed recovery of cytosolic Ca(2+). Such changes were not observed in EDL. It is concluded that the shift in myosin protein from type II to type I previously reported in both innervated and denervated wobbler muscles primarily takes place in the population of denervated muscle fibers. Since these muscles do not contribute to force generation, the transition is, therefore, of limited relevance for the contractile phenotype of the muscles. Instead, the slow contractile phenotype of wobbler soleus muscles seemed to be a consequence of reduced SR content of Ca(2+) ATPase.
