Spatial Coupling Characteristics Between Tourism Point of Interest (POI) and Nighttime Light Data of the Changsha–Zhuzhou–Xiangtan Metropolitan Area, China

Metropolitan areas, as pivotal hubs for global tourism and economic growth, necessitate sustainable spatial planning to balance development with ecological preservation. As critical geospatial datasets, nighttime light (NTL) and point of interest (POI) data enable the robust analysis of urban structural patterns. Building upon coupling coordination theory and polycentric spatial frameworks, this study investigates the spatial interdependencies between tourism POI and NTL data in China’s Changsha–Zhuzhou–Xiangtan Metropolitan Area (CZTMA). Key findings reveal high spatial coupling homogeneity, with three urban cores exhibiting radial value attenuation from city centers toward the tri-city intersection; concentric zonation patterns where NTL-dominant rings encircle high-coupling nuclei, contrasting with sporadic POI-intensive clusters in peri-urban towns; and sector-specific luminosity responses, where sightseeing infrastructure demonstrates the strongest localized NTL impacts through multiscale geographically weighted regression (MGWR). These findings establish a novel “data fusion-spatial coupling-governance” analytical framework and provide actionable insights for policymakers to harmonize tourism-driven urbanization with ecological resilience, contributing to United Nations Sustainable Development Goal (SDG) 11 (Sustainable Cities).

Rossby waves under time-varying shear with the complete Coriolis force

Large-scale Rossby waves are of great significance in influencing the weather and climate system due to the Coriolis force. In this paper, we derive a variable coefficient extended Korteweg–de Vries model to describe large-scale Rossby waves. This model is obtained from the potential vorticity equation, which incorporates the complete Coriolis force, using the Gardner–Morikawa coordinate transformation and perturbation theory. Subsequently, we obtain N-soliton solutions and breather solutions with horizontal Coriolis parameters through the Hirota bilinear theory. Moreover, based on different basic flows, we analyze the evolution of the amplitudes of Rossby waves, encompassing solitons, breathers, and their interactions. The results reveal that the horizontal component of the Coriolis force impacts the propagation trajectory of the solitons, potentially transforming elevation solitons into depression solitons during their propagation. Furthermore, the horizontal Coriolis parameters can modify the polarity of Rossby wave amplitudes and cause blockages to move in a zonal direction. The findings also suggest that the beta effect, the background westerly wind, and the horizontal component of the Coriolis force all influence the strength and evolution of the dipole blockage. In particular, a cotangent time-varying shear flow can lead to the transition from monopole blockage to dipole blockage. It is hoped that these discoveries will be useful in the study of atmospheric and oceanic Rossby waves.

A Singular Theory of Sensorimotor Coordination: On Targeted Motions in Space.

Gravity has long been purported to serve a unique role in sensorimotor coordination, but the specific mechanisms underlying gravity-based visuomotor realignment remain elusive. In this study, astronauts (nine males, two females) performed targeted hand movements with eyes open or closed, both on the ground and in weightlessness. Measurements revealed systematic drift in hand-path orientation seen only when eyes were closed and only in very specific conditions with respect to gravity. In weightlessness, drift in path orientation was observed in two postures (seated, supine) for two different movement axes (longitudinal, sagittal); on Earth, such drift was only observed during longitudinal (horizontal) movements performed in the supine posture. In addition to providing clear evidence that gravitational cues play a fundamental role in sensorimotor coordination, these unique observations lead us to propose an "inverted pendulum" hypothesis to explain the saliency of the gravity vector for eye-hand coordination-and why eye-hand coordination is altered during body tilt or in weightlessness.

Exploring Adaptation of Transportation Policy to Revolution Challenges: Evolution of Transportation Services and the Concept of Next-generation Solutions

This paper explores how transportation policy can respond to the transportation revolution driven by the diversification of business models through technological innovations, such as the Internet of Things (IoT) and Artificial Intelligence (AI), as well as the transformation of transportation equipment into information terminals. First, the evolution of transportation services and the concept of Mobility as a Service (MaaS) are organized to clarify the meaning of next-generation transportation services. Using a historical approach to transportation research and empirical knowledge of transportation coordination theory during the previous transportation revolution (marked by the emergence of automobiles and airplanes), this study examines the policy implications of MaaS through the concept of “interpretation circulation.” Finally, it summarizes the current status and challenges in implementing the Japanese version of MaaS and suggests future directions.

Interweaving academic insights: advancing university knowledge management through a strategic data fabric framework

Analysis of the Operation Mechanism of Rural Governance and the Realisation Path of Participatory Governance Based on Calculus Theory

Abstract With the development of the market economy, new farmers’ cooperative economic organisations have flourished, and with their organisational appeal, linkage of economic interests and attraction, they have brought together and driven a large number of farmers, accumulated rich social capital, become the emerging subjects of rural governance, and influenced and changed the existential ecology of rural governance. Based on the perspective of new farmers’ cooperative economic organisations, this paper provides a relatively comprehensive and systematic exploration of rural governance embedded in new farmers’ cooperative economic organisations with the help of coordination theory, institutional theory and the utility function in calculus theory. The specific operation, motivation, and guarantee mechanisms under the organization’s participation in rural governance are empirically examined. The mean value of the composite index of the level of rural governance under the participation of NPCE organisations is 0.633, with a coefficient of variation of 0.144. It is found that the participation of the new farmers’ cooperative economic organisations in rural governance is a stage-by-stage development trend. In the long run, rural governance will eventually shift to a pattern of multiple co-governance, led by the market, guided by the government, and directed by village organizations.

E-supply chain coordination and performance impacts: An empirical investigation

ABSTRACT This study addresses the critical need for coordinating electronic supply chain (E-SC) practices to maximize benefits for manufacturing firms. Despite existing literature, empirical studies have often overlooked the performance implications of such coordination. Using coordination theory, we argue that enhancing business value from E-SC investments requires integrating internal and external E-SC practices. We test three models to evaluate how coordinated practices impact operational and business performance, employing structural equation modeling on survey data from Omani manufacturing firms. The results confirm that effective coordination of internal and external E-SC practices mediates improved performance outcomes. This paper is the first empirical research to explore the mediating role of these coordinated practices in manufacturing contexts, highlighting several implications for the effective deployment and adoption of E-SC practices to achieve superior operational and business performance.

AN EXAMINATION OF RELATIONAL COORDINATION AMONG PAID AND FAMILY CAREGIVERS IN THE ARIC COHORT

Abstract The oldest-old (ages 85+) are disproportionately at risk for impaired function and reliant on support from caregivers. However, studies of caregiving typically fail to comprehensively enumerate and assess the capacity of both family and paid caregivers, shared care networks, and change over time. In this session we will describe the conceptualization and development of ARIC Cares, a caregiving study that will be embedded within the Atherosclerosis Risk in Communities Study (ARIC), a multisite prospective cohort of ~4,000 individuals ages 81-101 that has been characterized for >30 years. Existing studies of how caregiver factors relate to outcomes for older adults generally evaluate a limited set of measures specific to family caregivers (e.g., relationship to older adult). The role that paid caregivers play in meeting care needs in the community is consistently undervalued and less well studied. ARIC Cares will simultaneously assess family and paid caregivers and utilize the theory of relational coordination for understanding the dynamics of caregiving teams. ARIC Cares, which will focus on the end-of-life period and examine outcomes for older adults and their caregivers, will enumerate older adults’ care networks at 6-month intervals, in 4 diverse communities. Rigorous evidence regarding the caregiving experience, particularly focused on how teams of family and paid caregivers work together, could inform initiatives to improve quality of life among older adults and their caregivers. An understanding of these networks is critical as serious illness care, including complex dementia care, increasingly shifts to community settings where coordination between family and paid caregivers is vital.

일가정양립 법제도 영역의 정책조정에 대한 탐색적 연구

This study diagnoses the legislative linkage of parental leave and work-family balance support policies based on policy coordination theory and derives improvement tasks. To this end, the contents of five laws, including the “Act on Equal Employment for Both Sexes,” the “Employment Insurance Act,” the “Framework Act on Healthy Families,” the “Act on the Promotion of Creation of Family-Friendly Social Environment,” and the “Framework Act on Low Fertility and Aging Society” were analyzed in terms of policy goals, institutional means, and administrative systems. The results show that while related laws share the comprehensive policy goal of supporting workers' work-family balance, the setting and coordination of specific policy priorities are insufficient. In addition, there is a lack of linkage between individual policy instruments, and communication and cooperation between ministries and between central and local governments are limited. Therefore, this study proposes measures to improve the legal system for the integrated implementation of work-family balance policies, such as establishing a policy coordination governance system, reorganizing the system centered on service users, operating a pan-governmental policy council, and strengthening linkages of services at the local level. This study suggests that it is time for work-family balance policies, which have focused on quantitative growth, to seek qualitative leaps.

Finite-time control design for permanent magnet synchronous motor speed regulation system

This paper considers the finite-time speed regulation problem of permanent magnet synchronous motor (PMSM) servo system. Based on homogeneous system theory, a finite-time proportional-integral controller is first constructed for the d-axis current loop system, such that the desired current can be tracked in finite time. To overcome the influence of the unmatched load torque disturbance of the second-order model for the speed regulation system, a nonlinear integral dynamic is introduced. Then, based on an appropriate coordination and homogeneous system theory, a new finite-time proportional-integral-derivative controller is constructed. Strict theoretical analysis based on Lyapunov stability theory is provided to verify the finite-time stability of the corresponding closed-loop system. Finally, numerical simulation and experimental results are conducted to validate the effectiveness of the proposed finite-time control method.

Research on the Simplified Calculation Model and Parameter Analysis of Large-Size PBL-Stiffened Steel–Concrete Joints

To investigate the design principles and simplified calculation model of large-size PBL-stiffened steel–concrete joints, this study uses a Y-shaped rigid frame-tied arch composite bridge as an engineering background. Based on deformation coordination theory, a combination of theoretical analysis and numerical simulation was employed to derive a simplified calculation model that accounts for boundary conditions such as the stiffness of steel beam end restraints and the local bearing effect of the bearing plate. Parametric analysis of the steel–concrete joint was conducted. The results indicate that the derived simplified calculation model exhibits good accuracy and is suitable for calculating force transfer in various components of the steel–concrete joint under different boundary conditions. Using the simplified model, the effects of parameters such as steel–concrete joint length, connector stiffness, and structural axial stiffness on the axial force transfer in primary force-bearing components (connectors and bearing plates) were studied. The findings reveal that an excessively long steel–concrete joint does not effectively reduce maximum shear force; variations in connector stiffness primarily affect connectors farther from the bearing plate without changing the shear force distribution. Increasing the axial stiffness of the steel structure within a certain range can improve the maximum shear force in connectors, whereas increasing the axial stiffness of the concrete structure has the opposite effect.

Seeing the Whole Together Through Relational Mapping: A Method for Engaging in Complex Systems Change

Complex global challenges cut across organizational and sectoral boundaries, increasing calls for holistic responses. Seeing the whole across diverse stakeholders is challenging for participants in complex systems, yet doing so is essential for engaging effectively in systems change. A promising new method known as relational mapping, based on relational coordination theory, has been used to facilitate complex systems change. Here, we propose that relational mapping can be applied to help participants (1) see the whole in relation to the parts, (2) share their explicit and tacit knowledge, (3) engage in dialogue across distinct perspectives supported by the map as a boundary object, (4) reduce the impact of power differences, and (5) prepare to co-design interventions from multiple perspectives. This paper presents an illustrative case of relational mapping in the context of public administration in a South Carolina community engaging in complex systems change. Our analysis suggests a set of boundary conditions for the success of relational mapping, including the willingness of participants to seek integrative solutions to a conflict or problem and facilitation that is attentive to differential power and status among stakeholders. We conclude that relational mapping is a powerful, theoretically grounded method that enables the visual assessment of multi-level stakeholder relationships, preparing participants to engage in complex systems change and then present a template for use of relational mapping more broadly.

From data silos to seamless integration and coordination: a data-asset centric approach to smart hospital facility management

PurposeExisting hospital building operations involve numerous information technology applications and complex building systems; therefore, an intelligent facility management (FM) platform is required to ensure their continuous operation. To address the persistent issues of data silos, inefficient data interoperability, and workflow incoordination that have been identified in the current body of FM practice and literature, the present study develops a data-asset (DA) centric FM platform specifically designed for hospital buildings.Design/methodology/approachThis study proposes a semi-customized approach to develop the DA-centric FM platform for hospital buildings. To elucidate the precise function requirements of the hospital FM platform, focus group interviews are employed. By seamlessly integrating the as-built BIM model, IoT sensor data and FM workflow data, the BIM-based DA model with a data transfer mechanism is developed. The development of the FM platform with function modules in a case study is guided by a five-tier architecture and the coordination theory (CT). The case study provides an in-depth introduction to the applications of DA management, space management and maintenance management modules.FindingsThe capabilities of the developed DA-centric hospital FM platform are validated through the case application and user satisfaction survey, which assess data quality, automation level, operation efficiency, flexibility and functionality. For hospital FM activities, this DA-centric FM platform realizes data integration and seamless transformation, optimizes workflow coordination and enhances operation performance.Originality/valueThe initial scholarly contribution is the establishment of the BIM-based DA model, which serves as the data middle platform for continuous data integration, transmission and sharing within the FM platform. Subsequently, under the guidance of the CT, the business process of function modules is designed, improving the intra-module and inter-module workflow coordination. The developed DA-centric FM system along with its performance benchmarking application, assists facility managers and decision-makers in implementing smart operations for hospital buildings and achieving the management goals of safety, efficiency, energy savings and convenience.

Performance evaluation of industry-education integration in higher education from the perspective of coupling coordination-an empirical study based on Chongqing.

The coupling coordination between higher education and regional industries is an effective way to enhance the performance of industry-education integration and an important driving force for promoting sustainable economic and social development. This article aims to evaluate the performance level of industry-education integration in higher education from the perspective of coupling coordination between industry and education, and to analyze its sustainable development trends. To achieve this, a framework for the industry-education complex system is constructed based on the theory of coupling coordination, and a performance evaluation model for industry-education integration is established. The "structure-conduct-performance" (S-C-P) analysis paradigm of industrial organization theory is used to design a performance evaluation indicator system, and the entropy weight method is applied to assign weights to the indicator system. Empirical research is conducted on Chongqing based on statistical data from 2000 to 2022. The results show that: (1) During the sample period, the construction effectiveness of industry-education integration in higher education in Chongqing is relatively significant, and the coordination level between regional industries and higher education continues to rise. (2) The orderly development level of the two subsystems of regional industries and higher education alternately rises, jointly promoting the continuous improvement of the performance level of industry-education integration, which is the main driving factor for performance improvement. (3) The stagnation of the coupling strength between regional industries and higher education is a key obstacle to further improving the performance of industry-education integration. Industry-education integration is a systematic project that should be promoted collaboratively from the perspectives of the regional industrial subsystem, higher education subsystem, industry-education complex system, and external environment to continuously enhance the performance level.

Reconciling Accuracy and Feasibility for Barrierless Reaction Steps by the PCS/DDCI/MC-PDFT Protocol: Methane and Ethylene Dissociations as Case Studies.

Several enhancements have been introduced into state-of-the-art computational protocols for the treatment of barrierless reaction steps in the framework of variable reaction coordinate variational transition state theory. The first step is the synergistic integration of the Iterative Difference Dedicated Configuration Interaction (I-DDCI) and Pisa Composite Scheme, which defines a reduced cost, yet very accurate, computational workflow. This approach provides a near black box tool for obtaining 1D reference potentials. Then, a general strategy has been devised for tuning the level of theory used in Monte Carlo (MC) sampling, employing Multiconfiguration Pair Density Functional Theory (MC-PDFT) with dynamically adjusted Hartree-Fock exchange. Concurrently, partial geometry optimizations during the MC simulations account for the coupling between the reaction coordinates and conserved modes. The protocol closely approaches full size consistency and yields highly accurate results, with several test computations suggesting rapid convergence of the I-DDCI correction with the basis set dimensions. The capabilities of the new platform are illustrated by two case studies (the hydrogen dissociation from CH4 and C2H4), which highlight its flexibility in handling different carbon hybridizations (sp3 and sp2). The remarkable accuracy of the computed rate constants confirms the robustness of the proposed method. Together with their intrinsic interest, these results pave the way for systematic investigations of complex gas-phase reactions through a reliable, user-friendly tool accessible to specialists and nonspecialists alike.

A review of coordination compounds: structure, stability, and biological significance

Abstract Coordination compounds are molecules that contain one or more metal centers bound to ligands. Ligands can be atoms, ions, or molecules that transfer electrons to the metal. These compounds can be charged or neutral. When charged, neighboring counter-ions help stabilize the complex. The metal ion is located at the center of a complex ion, surrounded by other molecules or ions known as ligands. Ligands can be thought of as covalently bonded to the core ion through coordination. Understanding coordination theory in chemistry provides insight into the geometric shape of complexes and the structure of coordination compounds, which consist of a central atom or molecule connected to surrounding atoms or compounds. Inorganic coordination compounds exhibit different properties and are used in synthesizing organic molecules. The coordination of chemicals is vital for the survival of living organisms. Metal complexes are also essential for various biological processes, with many enzymes, known as metalloenzymes, being composed of metal complexes. These metal complexes occur naturally.
