Repetition for real-time coordination of action: Lexical and non-lexical vocalizations in collaborative time management

Repetition has often been argued to be a semiotic device that iconically signifies ‘more content’, such as intensity and plurality. However, through multimodal interaction analysis of materials in English, Estonian, and Swedish, this paper demonstrates how self-repetition is used to coordinate actions across participants and temporally organize the ongoing activity. The data are taken from infant mealtimes, pilates classes, dance training, boardgames, rock climbing, and opera rehearsals. Repetition of both lexical and non-lexical tokens can prolong, postpone, and generally organize segments of action as well as co-create rhythms and moves in a moment-by-moment reflexive relationship with other (non-vocalizing) participants. A crucial feature of repetitions is that they can be flexibly extended to fit the other’s public performance, its launching, continuation, and projectable completion. We argue that the iconicity of repetition emerges through its indexical relationship to other bodies, as a real-time jointly achieved phenomenon.

Hesperetin Inhibits Bladder Cancer Cell Proliferation and Promotes Apoptosis and Cycle Arrest by PI3K/AKT/FoxO3a and ER Stress-mitochondria Pathways.

Hesperetin (HSE) is a natural flavonoid derived from the hydrolysis of Hesperidin, which is mainly found in traditional natural Chinese herbs, such as Chenpi and Hovenia caryophyllus. HSE displays anti-inflammatory and antioxidant activities. However, its potential mechanism of action on bladder cancer (BLCA) remains unknown. The aim of this study was to investigate the potential mechanism of action of HSE on BLCA cells. Network pharmacology analysis was used to construct a composite target network, combined with Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis to identify HSE-induced cell death patterns and signaling pathway alterations. Cytotoxicity evaluation was determined by CCK-8 assay. A clone formation assay was performed to assess cell proliferative capacity. Scratch and Transwell assays were performed to evaluate cell migration and invasion ability. Hoechst 33342 staining was visualized to observe morphological features of apoptosis. Apoptosis, cycle distribution, reactive oxygen species (ROS) generation, and mitochondrial membrane potential (MMP) changes were examined by flow cytometry. Western blot analysis was performed to analyze the expression of key proteins associated with cell proliferation, apoptosis, cycle block, PI3K/AKT/FoxO3a and endoplasmic reticulum (ER) stress-mitochondrial pathways. Network pharmacology analysis was performed to identify 155 potential candidate targets of HSE-BLCA, and further topological analysis was performed to obtain 34 hub-gene. Enrichment analysis yielded patterns of death and key pathways, revealing that the anti-BLCA effect of HSE may be related to the positive regulation of PI3K/AKT/FoxO3a and ER stress-mitochondrial pathways. in vitro results showed that HSE blocked cell proliferation, migration, and invasion in a concentration-dependent manner and triggered apoptosis, G0/G1 phase blockade, ROS production, and MMP depolarization. In addition, Western blot results showed that HSE downregulated phosphorylated (p)-3-phosphoinositide-dependent kinase-1 (PI3K), phosphorylated (p)-AKT serine/threonine kinase 1 (AKT), phosphorylated (p)-Forkhead box O 3a (FoxO3a), anti-apoptotic proteins, proliferation-associated proteins, and cell cycle promoters, whereas the levels of proteins related to the expression of cell cycle regulators, pro-apoptotic proteins, and ER stress-mitochondrial pathway were up-regulated in BLCA cells by the intervention of HSE. PI3K agonist (YS-49) and ER stress inhibitor (4-PBA) partially or completely reversed HSE-mediated proliferation, apoptosis, and cycle blockade in BLCA cells. The anticancer effects of HSE in BLCA may be attributed to its coordination of actions, inhibiting cell proliferation, migration, and invasion, inducing apoptosis, G0/G1 phase arrest, generating reactive oxygen species, causing MMP loss, and engaging the caspase protein family. These actions are likely mediated through the PI3K/AKT/FoxO3a and ER stress-mitochondrial pathways. Thus, our findings suggest that HSE is a promising novel therapeutic candidate for the prevention and treatment of BLCA.

Analysis of Coordination Mechanisms during Collaborative Problem-Solving on an Interactive Tabletop Display

AbstractCoordination is an important aspect of group work. Previous studies have shown how collocated multi-user interfaces, such as interactive tabletops, support coordination by providing a shared space that enhances workspace awareness. However, only little is known about the coordination processes that occur during problem-solving on such shared devices and how the design of features and interaction techniques can impact coordination behaviour. In this paper we analyse users’ coordination mechanisms during joint manipulation tasks in Orbitia, an interactive tabletop-based problem-solving activity. The proposed design integrates a series of “breaches” seeking to challenge participants’ collaboration by confronting them to different limitations. We report on a case study with five groups of three users (N = 15), jointly solving tasks while facing different challenges related to the activity interface and the environment. By analysing 135 min of video material along with their transcripts, we identified nine different coordination mechanisms that relate to either coordination of information or coordination of actions. By exploring the occurrences of these mechanisms, we found that sharing unsolicited task-relevant information is a common coordination behaviour that can be observed at interactive tabletops, and that with breaches, more explicit coordination in the form of direct requests, orders, or shadowing is used.

Why did the “world of the 1960s” disappear? About the reasons for the decline of the youth protest movement in late 60s of the XX century in the countries of Western Europe and the USA

The article is about the reasons of the decline of the Western European and USA youth protest movement in late 60s of the 20th century. According to the authors, the main reasons for the decline of the Movement are: the spontaneity of the protests, the absents of the joint coordination of actions, mistrust political institutions, the narrowness and limitations of ideas and slogans). The change of attitude towards the youth by the government circles and public of the Western countries in the early 1970s played an important role in the minimization of protest activity. As the result of it was the development of a fundamentally new youth policy based on the “whip and gingerbread” method: on the one hand, there was a strengthening of the repressions against riots participants, and on the other hand, the involvement of youths representative into political, state, business and public institutions with the aim of integration began protest activists in public life. Finally, the new trends in the social and political development of the Western countries in early 1970s become the significant factor in the decline of the protest movement. Such trends included changes in economic, political and cultural interactions in countries of Western Europe and USA, in particular the deterioration of the economic situation, as well as the extension of the social elite at the expense of students and graduates of technical and economic faculties. Finally, the new trends in the social and political development of the Western countries in early 1970s becаme the significant factor in the decline of the protest movement, in particular the deterioration of the economic situation, as well as the expansion of the social elite at the expense of students and graduates of technical and economic faculties. This contributed to the further erosion of the social base of the protests and the focus of youth on their careers.

The latest approaches and technologies to increase the competitiveness of aviation enterprises in modern conditions

The article discusses the essence of the concept of enterprise competitiveness management, encompassing all enterprise management processes, such as production, sale of products, provision of services, and others. It has been identified that the spectrum of existing research on scientific approaches to competitiveness management requires some structuring and refinement, taking into account the latest trends and the specifics of the activities of aviation enterprises in modern conditions. A unique perspective on structuring scientific approaches to managing the competitiveness of aviation enterprises has been proposed, according to which the discussed approaches are categorized depending on the object, target parameters, scientific directions, innovative technologies, and combined objects. The advantage of such structuring lies in a better understanding of the specifics of existing approaches and the identification of innovative scientific approaches to enterprise competitiveness management that require further research. Special attention has been paid to the study of key aspects and specifics of the logistic approach, which involves finding a compromise and balance of interests and responsibilities, consistency and coordination of actions, subordination of partial to general, and measuring the results of activities not only from the perspective of resource savings but also the magnitude of losses caused by irrational actions of chain participants. The logistic approach to managing the competitiveness of aviation enterprises lies in the implementation of the supply chain management concept, aimed at effectively servicing demand and creating additional value for consumers, and realizes a customer-oriented approach to competitiveness management. Direct tools of the logistic approach that can be effective in managing aviation logistic processes have been identified in the article, such as ESG technologies, CALS technologies, Agile approach, IoT, Blockchain, Artificial Intelligence, robotic systems. The advantages of these tools and their application areas are indicated. Thus, the use of various approaches and technologies will enable aviation enterprises to find optimal solutions to enhance their competitiveness in modern conditions.

A catalogue of Galactic GEMS: Globular cluster Extra-tidal Mock Stars

ABSTRACT This work presents the Globular cluster Extra-tidal Mock Star (GEMS) catalogue of extra-tidal stars and binaries created via three-body dynamical encounters in globular cluster cores. Using the particle-spray code Corespray, we sample $N=50\, 000$ extra-tidal stars and escaped recoil binaries for 159 Galactic globular clusters. Sky positions, kinematics, stellar properties, and escape information are provided for all simulated stars. Stellar orbits are integrated in seven different static and time-varying Milky Way gravitational potential models where the structure of the disc, perturbations from the Large Magellanic Cloud and the mass and sphericity of the Milky Way’s dark matter halo are all investigated. We find that the action coordinates of the mock extra-tidal stars are largely Galactic model independent, where minor offsets and broadening of the distributions between models are likely due to interactions with substructure. Importantly, we also report the first evidence for stellar stream contamination by globular cluster core stars and binaries for clusters with pericentre radii larger than five kiloparsecs. Finally, we provide a quantitative tool that uses action coordinates to match field stars to host clusters with probabilities. Ultimately, combining data from the GEMS catalogue with information of observed stars will allow for association of extra-tidal field stars with any Galactic globular cluster; a requisite tool for understanding population-level dynamics and evolution of clusters in the Milky Way.

Supporting disaster relief operations through RFID: enabling visibility and coordination

PurposeIn the aftermath of disasters, humanitarian actors need to coordinate their activities based on accurate information about the disaster site, its surrounding environment, the victims and survivors and the supply of and demand for relief supplies. In this study, the authors examine the characteristics of radio frequency identification (RFID) technology and those of disaster relief operations to achieve information visibility and actor coordination for effective and efficient humanitarian relief operations.Design/methodology/approachBuilding on the contingent resource-based view (CRBV), the authors present a model of task-technology fit (TTF) that explains how the use of RFID can improve visibility and coordination. Survey data were collected from humanitarian practitioners in India, and partial least squares (PLS) analysis was used to analyze the model.FindingsThe characteristics of both RFID technology and disaster relief operations significantly influence TTF, and TTF predicts RFID usage in disaster relief operations, providing visibility and coordination. TTF is also a mediator between the characteristics of RFID technology and disaster relief operations and between visibility and coordination.Social implicationsThe many recent humanitarian disasters have demonstrated the critical importance of effective and efficient humanitarian supply chain and logistics strategies and operations in assisting disaster-affected populations. The active and appropriate use of technology, including RFID, can help make disaster response more effective and efficient.Originality/valueHumanitarian actors value RFID technology because of its ability to improve the visibility and coordination of relief operations. This study brings a new perspective to the benefits of RFID technology and sheds light on its antecedents. The study thus expands the understanding of technology in humanitarian operations.

ШЛЯХИ ВИРІШЕННЯ ЛОГІСТИЧНИХ ПРОБЛЕМ ПРИЧОРНОМОРСЬКОГО РЕГІОНУ УКРАЇНИ НА ТЛІ РОСІЙСЬКОЇ БЛОКАДИ ЧОРНОМОРСЬКИХ ПОРТІВ

The article is devoted to the analysis of logistical problems caused for Ukraine and the world by the Russian blockade of the Black Sea and sea routes of the Black Sea region. The author describes in detail the negative consequences of the blockade (a sharp reduction in the export of Ukrainian grain, an increase in world food prices, the threat of a food crisis in the countries of Africa and Asia, economic losses for Ukraine), explores ways to solve this problem, for example, the organization of one's own grain corridor with the help of increasing military presence in certain parts of the Black Sea, as well as the use of alternative ways of transporting products through river ports, railways and roads, compares the economic feasibility and general capabilities of Ukraine and its allies in providing cargo transportation, calculates the total effect of simultaneous use as the Ukrainian "grain corridor" itself, as well as a set of possible alternative modes of transportation. The article reveals the main problems of using alternative methods of transportation of export products of Ukraine, as well as possible ways to solve these problems. The author emphasizes the significant economic losses that Ukraine received from the blockade of the Black Sea by the Russians, primarily because the export of food from our country is a rather important source of filling the state treasury with foreign currency, which makes it possible to restrain possible, large inflation in wartime conditions, and to reduce currency interventions by the National Bank of Ukraine. The author also describes in detail the military maneuvers used by the representatives of the armed forces of Ukraine to reduce the presence of the Black Sea Fleet of the Russian Federation in the western part of the water area, such as: the sinking of the cruiser "Moskva", the return to the world of control of gas and oil production facilities, as well as the liberation of the island "Zmiiny". It was emphasized that the illegal Russian blockade of the Black Sea is a serious challenge for Ukraine and the world. Overcoming it will require joint efforts and coordination of actions at the international level.

Evaluación del Impacto Territorial, Análisis de Costes y Beneficios y principio de No Causar Daños Significativos para el diseño de obras y planes sostenibles

Economic, financial, and spatial analytical models are known to be integral parts of large territorial works and plans. Cost Benefit Analysis (CBA) and, newly, Territorial Impact Assessment (TIA) and Do Not Significant Harms principle (DNSH) are required to support the decision-making and evaluation process underlying climate change, initial strategic investment confirmation and final reporting. Looking at them from an economic-geographical perspective and drawing inspiration from ongoing experiences in Europe and Italy, methodological and operational guidelines are suggested in the paper to address this issue, so that both the environmental and social costs are reflected in the costs/prices/returns and in the mitigation of the public works impacts, creating a strong link between economy, territory, and environment, so that externalities can become internalities. The underlying thesis is that, knowing the territorial impacts generated by the TIA and the sustainable consistency of the project with the DNSH taxonomy, it is possible to adopt compensatory and mitigation actions, including in the related CBAs; and, at the same time, to minimise the costs resulting from the lack of policy coordination in territorial action between regional and local plans, both horizontal and vertical, when large infrastructure projects come from top-down decision as in the case of Recovery and Resilience Facility plan

ІНСТИТУЦІЙНЕ ЗАБЕЗПЕЧЕННЯ УПРАВЛІННЯ ПОБУТОВИМИ ВІДХОДАМИ

The article examines the main results of the legislative reform in Ukraineʼs municipal waste management sector. It identifies key issues hindering the effective implementation of new legislative norms, such as bureaucratic obstacles, insufficient funding, and the ongoing war. The roles of the national, regional, and local levels of government in the municipal waste management process are analyzed, highlighting the necessity of their interaction. The importance of coordinating actions among all stakeholders to ensure sustainable development and effective municipal waste management is emphasized. Ukraine’s Constitution, adopted in 1996, laid the foundation for a legal state and established fundamental principles of environmental safety, including the right to a safe environment and the state’s duty to maintain ecological balance. However, the previous Waste Management Law, despite being in effect for over 20 years, was ineffective due to a lack of systematic approach, poor coordination, and outdated infrastructure. In response to these challenges, the government initiated a comprehensive legislative reform to align with European standards and improve coordination. The new Waste Management Law, adopted in 2023, aims to address these issues. However, many necessary changes are still in progress, delayed by bureaucratic obstacles and the ongoing war, which has shifted government priorities towards national security. A critical challenge remains the coordination of actions between different levels of government and waste management entities. Effective waste management requires close interaction between national, regional, and local levels, encompassing infrastructure development, waste collection, transportation, and resource allocation. Such coordination is crucial for achieving sustainable development and environmental safety in Ukraine. The article underscores the need for special procedures to accelerate the approval of critically important environmental legislation. While international organizations often push necessary decisions, aligning national strategies with European integration and funding conditions, the active role of national, regional, and local authorities is essential. Improved cooperation and communication among all levels of government and stakeholders can significantly enhance the efficiency of municipal waste management systems in Ukraine.

Механизмы зрелости регионального инвестиционного стандарта как фактор повышения инвестиционной активности территорий Российской Федерации

The research relevance is determined by the need to assess the potential of transformations in the activities of public authorities to attract investment in regions and municipalities. The article considers the processes of dynamic changes in the mechanism of the regional investment standard, determined by the investment needs of the country's regions and implemented in the form of elements of fine-tuning the current mechanism. The authors determine the results of the implementation of the second-generation regional investment standard and identify the reserves for the development of its tools, substantiate the processes of transformation and maturity which meet modern macroeconomic challenges and priority goals of economic growth. The maturity mechanisms of the third-generation regional investment standard are briefly characterized. The correlation of new elements of regional and municipal investment standards is determined. The problem field of interfacing these mechanisms in the process of their implementation is outlined. At the stage of unification of elements of the municipal investment standard and coordination of actions of regions and municipalities to increase investment activity, generalization of regional experience in order to identify successful practices for their further replication is of practical interest. The conditions of applicability of the regional investment standard maturity mechanisms for increasing the investment activity of territories are: unification of approaches to the implementation of elements of the municipal investment standard; interfacing of elements of regional and municipal investment standards in order to create conditions for the implementation of proactive investment strategy of municipalities; generalization and replication of successful practices of territories on the integration of the municipal standard in the system of regional investment policy. The results of implementing the regional investment standard should be: the dynamics and structure of investments (growth of the volume of investments); increase (taking into account possible expansion) of the number of investors; growth of the degree of trust and satisfaction of business with actions of the authorities.

ENVIRONMENTAL GEO-INFORMATIONAL MONITORING SYSTEM FOR THE CIVIL AND FIRE SAFETY SERVICES OF UKRAINE

Background.The purpose of the work is the development of a new ecological and geo-informational system for monitoring emergency situations, which allows quick predicting the consequences of various natural and man-made hazards at the stage of preventing their occurrence. This applies to possible cases of destruction on territories where there is a threat of flooding and, accordingly, the protection of coasts, structures, roads on mountain slopes, bridges, tunnels and dams built on soils with certain geological and geophysical characteristics, as well as the occurrence and spread of fires and pollution of air, water and soil with harmful substances associated with them. Methods. To implement the methods, available and purchased licensed software is used, creating convenient algorithms for solving practical tasks of civil protection. Information processing based on the used software packages that allow quickly processing large amounts of information, reducing the level of poor processing and data distortion. Results. An ecological and geo-informational monitoring system has been developed, designed to ensure the coordination of actions of civil and fire protection services in order to increase the efficiency of responding to emergency situations of natural and manmade origin. By conducting experiments, model results were obtained, which make possible to theoretically calculate and determine the critical permissible stress-deformed states of the soil massif in the area of engineering structures, bridge structures, to warn about the possible destruction of the massif due to excess stress and deformation under the action of loads. Proposed localization of fire-hazardous zones based on satellite data. As part of the developed system for space monitoring of forest fires, satellite information is used, in particular, the AVHRR radiometer of the Terra satellite. On its basis, a temperature map of the regions of Ukraine was formed. Conclusions. The geo-informational monitoring system was created to prevent the risks of emergency situations (including the destruction of slopes, fires, etc.) using software products, creating databases for mapping potentially dangerous objects. Its application will make it possible to assess the consequences of possible emergency situations of a natural and man-made nature and minimize their negative impact on the environment. The developed geo-information system can be used to coordinate the actions of civil and fire protection services, as well as increase the efficiency of emergency and rescue measures.

Política Ambiental Brasileira: responsabilidade compartilhada e desmantelamento

Abstract The article reviews Brazilian environmental policy, observing its central mechanisms, arguing that these are based on a conception of shared responsibility in the care for nature that has recently been undermined. From three approaches of political theory that discuss the problems of coordination of action, deliberation, and environmental justice, we analyze the institutional mechanisms of responsibility as protection, participation, and control, observing their relevance and justification for environmental policy. The article uses empirical documentary data to reflect on the potentials of the environmental policy model in the face of the possible implications of its deformation, concluding that the shared character of responsibility in environmental policy is the central focus of the changes that have been occurring, which puts an important democratic dimension at risk

ПРОГНОЗ ФАКТОРОВ, ОКАЗЫВАЮЩИХ ВЛИЯНИЕ НА ПОКАЗАТЕЛИ ИННОВАЦИОННОЙ АКТИВНОСТИ РЕГИОНОВ РОССИИ

the article examines the problem of limitations of existing rating models in forecasting and analyzing the development of innovation processes in a regional context due to limited possibilities for integrating various factors, such as educational systems and financial instruments. The need to develop and implement new forecast models that take into account multiple aspects related to education and the financial component of regional development is emphasized. The study also addresses the importance of socio-economic development in determining the readiness of regions to introduce innovations and create an innovative economic environment. The article presents an analysis of the factors influencing the innovative development of regions, with an emphasis on the level of monopolization of the market environment as an important factor affecting the dynamics of innovation, and also puts forward proposals for stimulating technological innovation and ensuring their financial support to improve financial stability at the state and regional levels. Using econometric modeling methods, the authors assess the impact of various variables. Studying the impact of these factors on the dependent variable allows us to determine their significance for the economic process and the development of resource management strategies. It is shown that investments in innovative research, human resources, educational structure and technological parameters of production have a significant impact on innovative activity. The study is conducted using econometric modeling techniques, including multiple linear regression and short regression models to identify significant factors. Models are checked for compliance with the conditions of the Gauss-Markov theorem, heteroscedasticity and autocorrelation of residuals using appropriate statistical tests. The results of the analysis confirm the statistical significance and adequacy of the models, and also allow us to identify key factors. At the same time, opportunities for improving the coordination of actions to develop the innovative potential of regions are identified based on the results of econometric modeling.

Statistical match reports of the 2022 volleyball World Championship in the context of network analysis with Gephi

Background and Study Aim. Modern volleyball teams participating in tournaments provide extensive statistical data about their actions. These data are available for analysis and represent a valuable source for assessing the potential and future success of both individual athletes and teams as a whole. In this context, tools such as Gephi become particularly valuable for visualizing and analyzing events at high-level tournaments. Our study aims to create and analyze network models of interaction among men's volleyball teams during the qualifying matches of the 2022 World Championship using the Gephi software.
 Materials and Methods. For the research, data were obtained from a volleyball statistics website renowned for its extensive database. The study centered on Group C, comprising the teams: Poland, USA, Mexico, and Bulgaria. Data from six matches were extracted into Microsoft Excel tables and then converted into CSV format. The data from these tables were processed using the PyCharm programming environment and Python code. Visualization and analysis of the data were conducted using Gephi.
 Results. The results of the data processing highlight the professional expertise of the teams. The average values for all primary metrics underscore the teams' proficiency in executing fundamental actions at an elevated level. Eigenvector centrality helps determine the significance of nodes in the graph. The graph's density is 0.601, suggesting a relatively dense network of connections within the team. This indicates that volleyball players frequently engage with one another and share information on the court. Such extensive interaction can lead to enhanced coordination and efficiency in team actions. The parameter ε has a value of 1.0E-4, denoting high computational precision. The average interaction degree among volleyball players stands at 46.244. This measure denotes the interaction intensity among team members, hinting at the overall court activity. The modularity measure is 0.483, which signals the structural organization of the graph rooted in modularity. The graph comprises 5 modular communities, hinting at shared characteristics and cohesion among players within these groups. The HITS (Hyperlink-Induced Topic Search) metric assesses the node significance in the graph in terms of hubs and authorities. High HITS values pinpoint pivotal players acting as hubs, signifying their numerous connections with fellow teammates. Such players are crucial for facilitating information flow and coordination within the squad.
 Conclusions. Utilizing statistical match reports in volleyball, combined with the Gephi software, offers a deeper insight into the dynamics of player interactions. This aids in pinpointing key players, refining team strategies, and enhancing court coordination. Coaches are advised to leverage these tools for an in-depth evaluation of gameplay instances and to make informed decisions. Network analysis methodologies might soon be indispensable tools in the contemporary coaching toolkit.

The Structure of Network Administration on the Example of the Organization Market Surveillance Regarding Product Safety in the European Union

This article examines how product surveillance actors operate in the EU’s network structure, with a focus on forms of cooperation. Specifically, the study explores coordination systems adopted in market surveillance to demonstrate the network structure’s suitability for implementing the European Union’s policy on product safety assurance. The paper aims to demonstrate that in the context of the rapidly evolving e-commerce industry and the rise in cross-border sales of goods to the EU, market surveillance is ensured through a legal framework that involves cooperation between surveillance authorities and economic operators at both the national and EU level, within a network structure. The effectiveness and efficiency of this approach is established through the coordination of actions and sharing of information among the entities involved.

MANAGEMENT MODEL OF CORPORATE TRADE SYSTEM

The purpose of the article is to develop a model for managing a corporate trading system and define the principles that ensure its use. Methodology. The research methodology is based on the dialectical and systemic approach, i.e., the activities of the components of the business system are considered in their interconnection and interdependence. The methods of multidimensional logic, formalisation, structural synthesis, modelling and scientific generalisation are used to develop the management model of the business system. Results. The evolution of the business trading system reflects changes in space and time. It is impossible to change the scale of its activities without introducing managerial and organisational innovations. Corporate management is based on a three-level hierarchical structure: shareholders, board of directors and top management. The effectiveness of corporate management in commerce is determined by the degree of centralisation of management decisions. Corporate management and its senior executives ensure the achievement of the system's objectives, control and plan its development. A unified strategic management centre carries out strategic management of business units and internal coordination of actions, change management, while at the same time giving them the right to independent operational management. Separation of strategic and operational management subsystems allows to create a management system combining strategic objectives and performance parameters. Practical implications. The practical results can serve as a basis for further research on ways to improve the strategic and operational management of business units that are part of the corporate trading system, taking into account changes in the internal and external environment. Value/Originality. The proposed model of corporate trading system management allows to better understand the essence of the management process, provides strategic management of their activities from a single strategic management centre and gives the right to independent operational management.

Scale-up Integrated Care for Chronic Diseases in Belgium: a process evaluation of policy dialogues and roadmap interventions

Background. The goal of more integrated care has been on the Belgium health care policy agenda since 2007 with the start of disease specific care trajectories, reports on chronic care and pilot projects at local level. While there is consensus on what needs to be done, the process of how it should be done is much more uncertain. Scale-up of integrated care is complex, because it requires multi-stakeholder action and intersectoral coordination at individual healthcare practice, organizational, and political/system levels, and tailoring to the context in which it is delivered. There is little research on how to scale-up such complex and adaptive interventions.
 The SCUBY project aimed to contribute to scale-up of integrated care through development of evidence-based roadmaps and policy dialogues. This evaluation study examines the SCUBY scale-up intervention, by looking at its implementation outcomes, mechanisms of impact and the interaction with the political, policy and societal circumstances in the Belgium context.
 Methods. The ‘process evaluation for complex interventions’ by the MRC was the evaluation framework. Policy dialogues were defined as the SCUBY-team engagements with key stakeholders to develop and implement roadmaps. They comprised structured formal events, one-to-one interactions with key stakeholders, workshops, consultations, and joining ongoing dialogues of stakeholder networks. The roadmap was a scale-up strategy and included activities, a timeline and a description of the evidence base and key partners/stakeholders involved (change team). Data collection tools included policy dialogue reporting forms and surveys, key informant interviews, policy document review and a project diary. Descriptive and thematic analyses are conducted, together with a policy mapping. 
 Results. The SCUBY team conducted 79 meetings classified as policy dialogues, most of them being small group meetings or network meetings organized by partners. SCUBY organized 6 major policy dialogues and invited a mix of beneficiaries, health system administration representatives, policy makers (from federal and regional level), health care providers and their representative organizations, people involved in organization and coordination of care, care users, and scientific stakeholders. Three themes emerged as being the most important areas for the roadmap: A) primary care practice organization (change management and advocating for primary care nurses); B) data and monitoring (chronic care indicators at primary care practice level and for population health management in Primary Care Zones); and C) healthcare financing (budget for chronic care that stimulates quality and new provider payment models). The roadmap comprised subthemes, with internal objectives (to be reached with our project resources) and external objectives (beyond out sphere of control) and activities. 
 Discussion. Our findings emphasize the importance of adopting a collaborative, networking approach via the organization of various small-size and bigger-size policy dialogues, in order to create real-world impact, by building synergies and coalitions and our researcher team generating boundary spanning skills, as more proximal outcomes. The variation in progress made per roadmap theme was anticipated because of our level of involvement, expertise and resources available. The change team had to find the right balance in the trade-off between relevance and feasibility of certain scale-up strategies.
