Conceptual Frameworks for Conversational Human-AI Interaction (CHAI) in Professional Contexts

/in /by

Artificial intelligence (AI) is revolutionizing sectors like financial services, healthcare, and education, driving unprecedented progress and fostering innovation across domains. In this backdrop, basic conversational interface aka chat emerged as the predominant way to interact with AI systems. However, the current Human-AI (H2AI) conversations are fraught with a host of challenges necessitating a critical exploration into their design, strategy, and implications. Human-AI interaction design is hindered by fragmented and disjointed technology-driven approaches that lack design-led strategies to address emotional, adaptive, and holistic aspects of the field. This systematic study addressed this issue by developing conceptual models and frameworks integrating emotional, adaptive, and holistic social dynamics into Human-AI conversation design in professional settings. The comprehensive literature review spanning communication studies, user experience frameworks, design process models and conversational AI technologies revealed four research gaps. Through a multiple case study analysis across various industries, we developed four significant recommendations to enhance Human-AI interaction design. First, a typology of 12 Conversational Archetypes was established, providing a framework to inform dynamic and purpose led conversations in professional settings. Second, the Adaptive Conversational Interaction Dynamics (ACID) framework was introduced, integrating five dimensions—Conversation Management, Expertise and Competence, Emotional Intelligence, Trust and Credibility, and Personalization—to improve user engagement and satisfaction. Third, the Dynamic Experience Design (DxD) process emphasized a symbiotic approach with User Resonant Design principles and to create emotionally resilient and adaptable AI systems. Finally, the Conversational Human-AI Interaction (CHAI) framework integrated interactional, emotional, and ethical dimensions, ensuring AI systems are empathetic and ethically grounded. These contributions offer a comprehensive approach to designing advanced conversational AI that is responsive and adaptive. Further research needs to be undertaken to validate these frameworks through qualitative studies to ensure applicability across wider contexts, scenarios and cultures.

Bioprospecting of Marine Fungi for Production of Extracellular Protease

/in /by

Proteases from microorganisms have attracted much attention in the last decade because of their gigantic potential in various industrial processes due to their proteolytic activity such as detergent, textile, leather, dairy, and pharmaceutical preparations. However, proteolytic enzymes from microorganisms are preferred in the industrial application of enzymes due to their technical and economic advantages. In the present research work, protease-producing microorganisms were isolated from marine soil samples and screened for protease-producing ability using skim milk agar. Among twenty-three isolates, nine isolates were protease positive indicated by the clear zone around the colony. In quantitative screening, the highest protease activity was observed with JML 15 (144.72 U/ml) and JML 8 (107.92 U/ml) and selected for further investigation. Based on the molecular characterization and phylogenetic studies, the selected isolates were identified as Penicillium lagena JML 8 (PP987316.1) and Penicillium oxalicum JML 15 (PQ160092.1). The results showed that JML 15 and JML 8 had great potential to be used for the production of protease enzymes and upscale for industrial production.

The Influence of Price and Brand Quality on Market Orientation is mediated by Social Media Marketing

/in /by

This research analyzes the factors that influence market orientation in the retail industry, especially supermarkets in Batam City. People tend to want convenience and comfort in shopping, leading to a preference for supermarkets that are clean and modern and provide a variety of products. Batam, as a strategic industrial city, has tight retail competition with the development of minimarkets such as Indomaret and Alfamart. The research used a quantitative method with a questionnaire distributed to 266 respondents, measuring variables such as price, brand loyalty, product quality, service quality, stock, social media marketing, and market orientation. The research results show that price and stock have a significant influence on market orientation, while brand loyalty, service quality and social media marketing have varying influences. Product quality has a significant effect on social media marketing, but social media marketing is not significant on market orientation. The limitation of this research lies in the limited variable focus. It is recommended that further research add variables such as customer satisfaction, purchase intention, and consumer decision to expand understanding of the factors that influence market orientation.

In Thailand, there are limited studies that explore the intentions of Thai youth to undergo facial cosmetic procedures. The research’s purpose is to investigate the reasons that make Thai youth and teenagers undergo facial cosmetic procedures. The correlation between personality traits and the tendency to undergo cosmetic procedures among Thai youth in the Bangkok Metropolitan area was studied using an online questionnaire based on the personalities under the Big Five Inventory-10, including agreeableness, conscientiousness, extraversion, neuroticism, and openness to experience. The Statistical Package for the Social Sciences (SPSS) was used to analyze the data. There are 427 participants in the survey with 70.02% females,an age range of 16-18 and mostly students. The tendency in receiving cosmetic procedures is significantly different between genders among Thai youth. The tendency of receiving cosmetic procedures is significantly different among Thai youth with different amounts of income. Agreeable personalities are significantly different between genders, but there is no correlation between agreeableness and tendency to obtain facial cosmetic procedures, and women are more likely to receive facial cosmetic procedures than men do regardless of agreeableness.

Dirt Score in Large White Yorkshire Piglets during the Postweaning Period Reared on Different Floor Types

/in /by

An experiment was carried out on 24 Large White Yorkshire piglets of either sex at the pig unit of LFC of C.V.Sc., Rajendranagar, Hyderabad from weaning (56days) to 126 days. Piglets were reared on four types of flooring systems i.e., T1 (control group) reared on the concrete floor, T2 rubber mat, T3 elevated slatted floor, and T4 reared on soil floor. The floor space provided was 1.5 m2 per piglet during the post-weaning period. Pig cleanliness was assessed using a five-point scale on 4 anatomical areas: rear, back, and both flanks, and each area was given a score from 0 to 4. The cleanliness score was increased as the age advanced from first to ninth fortnight in all floor types. The overall mean cleanliness scores of LWY piglets maintained on four different floors was 2.21 ± 0.06, 2.57 ± 0.04, 0.63 ± 0.02, and 2.44 ± 0.03 in concrete, rubber mat, elevated slatted, and soil floor respectively. The overall mean dirt score of piglets reared on rubber mat floor was significantly (P<.0.01) higher than the piglets on the elevated slatted floor, but it was comparable with concrete and soil floor.  The higher cleanliness score of the piglets reared on rubber mat floor were dirtier than piglets on concrete and soil floor whereas, the piglets reared on elevated slatted (low score) were cleaner than rubber mat, soil, and concrete floors.
