Current Status and Evolution of Shared Mental Models Based on Bibliometric Analysis

引用

Journal of Systems Science and Information 2024年第4期12卷 433-456页

作者： kristina KONSTANTINOVA Siran FANG Xiaoxu ZHANG School of Economics and Management University of Chinese Academy of Sciences Academy of Mathematics and Systems Science Chinese Academy of Sciences Center for Forecasting Science Chinese Academy of Sciences

The cornerstone of most management research revolves around improving productivity and team performance. A crucial factor influencing team performance is the shared mental model that team members hold regarding task and team member related issues. This concept has garnered increasing attention from scholars, resulting in an abundance of literature. However, there remains a noticeable scarcity of a comprehensive literature review that combines both quantitative and qualitative analyses of shared mental model studies. In order to grasp a comprehensive understanding of the current status and future trends in the area, this study employs a bibliometric approach to review the literature on shared mental models published in the Web of Science Core Collection database from 1992 to 2023. Co-citation analysis is employed to thoroughly scrutinize the structure of this research area, computationally highlighting research hotspots, revealing potential future research directions and applications, as well as pinpointing pivotal turning points and landmarks in the field. Through scientific bibliometric analysis of knowledge structures and emerging trends, this review makes a substantial contribution to the contemporary literature on shared mental models, providing valuable insights for researchers and practitioners in the field.

Development of a Proof-of-Concept Multi-Method Computer Simulation to Support Rural Healthcare Disaster Preparedness Planning

引用

International Journal of Disaster Risk Science 2024年第3期15卷 346-358页

作者： Thomas A.Berg kristina W.Kintziger Julie Suzuki Crumly Scott A.Lawson Carole R.Myers Tracey T.Stansberry College of Nursing University of Tennessee Knoxville Department of Environmental Agricultural and Occupational Health University of Nebraska Medical Center Public Health and Healthcare Oak Ridge Associated Universities

Due to a lack of resources, rural communities often face challenges when planning catastrophic events. This project involved applying systems thinking and model-based systems engineering to develop a proof-of-concept, multi-method computer simulation and then determining whether the simulation could be used to assess the efficacy of disaster planning approaches on health outcomes in rural communities, as a function of primary healthcare. The project focus was a rural or non-urban healthcare system experiencing a natural hazard. Both system dynamics and discrete event models were incorporated to represent subsystem operations, crucial disaster responses, as well as three key response systems: public health, emergency management, and healthcare. The subsystem models included several components: policies/procedures, communications,resources, exercises/drills/training, healthcare space and staff, and the flow of affected people into and through the *** combined simulation can serve as a first step to a more comprehensive approach to helping rural communities achieve more efficient and effective healthcare planning for disaster responses.

Deep phenotyping and genetic characterization of individuals are fundamental to assessing the metabolic status and determining nutrition-specific requirements. This study aimed to ascertain the utmost effectiveness of personalized interventions by aligning dietary adjustments with both the genotype and metabolotype of individuals. Therefore， we assessed here the usefulness of a polygenic score (PGS) characterizing a potential pro-inflammatory profile (PGSi) as a nutrigenetic tool to discern individuals from the Danish PREVENTOMICS cohort that could better respond to precision nutrition (PN) plans， specifically targeted at counteracting the low-grade inflammatory profile typically found in obesity. The cohort followed a PN plan to counteract the pro-inflammatory profile (PNi group) or generic dietary recommendations (Control) for 10 weeks. PGSi was applied for genetic stratification (Low/High). The effects of the intervention on anthropometrics and biomarkers related to inflammatory profile and carbohydrate metabolism were assessed. Around 30% of subjects had a high genetic predisposition to pro-inflammatory status (high-PGSi). These individuals demonstrated the most effective response to the dietary plan， experiencing improved body composition， with significant decreases in body weight (△: -4.84%; p=0.039) and body fat (△: -4.86%; p=0.007)， and beneficial changes in pro- and anti-inflammatory biomarkers， with significant increases in IL-10 (△: 71.3%; p=0.025) and decreases in TNF-α (△: -3.0%; p=0.048)， CRP (△: -31.1%)， ICAM1 (△: -5.8%)， and MCP1 (△: -4.2%) circulating levels， compared to low-PGSi individuals. Both phenotypic and genetic stratification contributed to a better understanding of metabolic heterogeneity in response to diet. This approach allows for refinement of the prediction of individual requirements and potentially for better management of obesity.
