The article's purpose was to econometric substantiate the peculiarities of achieving a synergistic effect and sources of economies of scale for participants in entrepreneurial networks, for example, industrial enterprises in Ukraine. The regression analysis method has been used to identify sources of economies of scale of production, which change affects the efficiency of enterprises. With the elasticity coefficient, the features of the manifestation of the effect of economies of scale for 106 network and non-network enterprises were determined, taking into account the organizational life cycle of the development. It was revealed that, despite the ephemeral nature of the economies of scale, network enterprises are characterized by longer nature as a component of the synergistic effect of production activities and a decrease in costs, regardless of the development cycle of the organization. The results obtained can be useful as a basis for strategic planning in business integration.

The relevance of the study is due to the gradual replacement of hierarchical integration structures with network ones, which allows participants to form additional synergistic effects. This trend requires the development of new management methods for complex polysubject formations that unite diverse participants. The purpose of the article is to substantiate the methodology of adaptive management of industrial ecosystems, through the directed distribution of income generated by additional synergistic effects. The research methodology is based on the model of performance index normalization, which allows the subject of management to set the priority and levels of change in the income of participants in the integration network structure. The results of the study make it possible to assess the structure and dynamics of the income allocation of the integrative structure participants, to draw a conclusion about the distribution of income received through synergistic effects with a obvious asymmetry. The obtained results of ranking the change in the share of income based on the parameter of measuring the increase in the share of income made it possible to compare the existing values with the reference ranking of the increase in income within the framework of compliance with two strategic vectors for the development of integrative structures: commercial feasibility and development of the territory.

The formation of blockchain industrial ecology can help improve the open and efficient value synergy network, and this paper seeks to clarify the value relationship among industrial units and the trend of synergistic evolution of blockchain industrial ecosystem. Based on value co-creation theory, the blockchain industrial ecosystem synergy evolution process is analyzed, and the composite system synergy model is used to empirically investigate the evolution synergy of China’s blockchain industrial ecosystem from 2015 to 2020. The results show that: although the development level of China’s blockchain industry ecosystem continues to improve, it is still at a low level, and the policy-driven effect is obvious. There is a large disparity in the orderliness level of each subsystem of the blockchain industry ecosystem, and the industrial integration and application implementation are in a good situation, while the blockchain enterprises, located in the value pivot subsystem, are in a relatively tough position, and China’s blockchain industry ecosystem is overall in a state of reconciliation and has not yet formed a synergistic effect. Handling the synergistic relationship between the government, the market and other value-supporting units, and blockchain enterprises is the top priority for further promoting the synergistic evolution of the blockchain industry ecosystem.

This paper describes the use of neural networks to compute the orientation of a part from the output signals of an inertial sensor which is a device for determining the location of parts by measuring their inertial parameters. The paper investigates an approach for increasing the accuracy of the computed orientation. This involves employing a group of neural networks and combining their outputs. The paper presents the results obtained for several neural network combinations. These show that the accuracy achieved in a combined system is higher than that of its individual components provided the number of components is not too large.

The development of the digital economy in the modern world requires solving the issue of security of Industrial Internet of Things (IIoT) applications. A large number of distributed, network-based, IIoT devices managed by intelligent programs (software agents) require protection. A successful attack on any IIoT device will lead to hacking of the IIoT application and to large financial losses, as well as to the termination of the IIoT application, therefore, the research topic is relevant. The purpose of this article is to radically solve the security problem of the IIoT application by developing a blockchain architecture of the application. The authors were tasked with investigating all aspects of the blockchain system that ensure the security of IIoT application devices. The peculiarity of the blockchain system is that its participants are software agents that control the application devices. As a result of the research, the concept of the blockchain architecture of the IIoT application is proposed. He mechanisms of consensus of intelligent programs of IIoT devices as equal active participants of the blockchain network are investigated. The consensus mechanism and the cryptographic system of the distributed registry of the blockchain network increase the information security of the IIoT application. The synergistic effect of the blockchain system and intelligent systems of software agents of IIoT application devices significantly increases the efficiency of the solution. Intelligent systems of software agents and IIoT applications are effectively trained on the blockchain platform, and as a result, we get a decentralized supercomputer in the form of a blockchain system.

Full textAbstract:
Although tourism has increasingly become an important activity with wide influences on the economic, social, and spatial development of a city, knowledge and interest mostly remain on its industrial performance and promotion. The synergy between tourism and city development is largely overlooked in many cases, resulting in suboptimal design and planning of city tourism activities and unfledged potentials of city development. The aim of the paper is to propose a view of tourism–industrial complex based on a synergistic perspective in order to clarify the systematic characteristics of urban tourism in an integrated, sustainable manner. Availing of bibliometric methods and drawing on city/urban tourism literature, this paper proposes a concept of tourism–industrial complex to cover current complicated and various tourism activities that are embedded in cities at diverse levels regardless of social, economic, and spatial factors. Then, four types of tourism–industrial complexes are proposed, including demand-driven, resource-dependent, externally forced, and hybrid-driven models. Due to the networked connectivity of urban tourism, urban backgrounds, tourism industry, and external circumstances all contribute to a coupling the tourism city development system. The results provide theoretical constructs and policy recommendations for optimization and sustainable city and tourism development.

Full textAbstract:
Purpose The synergistic effect of functionalization of multi-walled carbon nanotubes (CNT) using KMnO4 oxidation and initial tensile deformation on the electrical resistance of nanotube network/polyurethane composite subjected to elongation was studied. Design/methodology/approach Though the initial deformation irreversibly changed the arrangement of carbon nanotube network, subsequent cyclic elongation confirmed stable resistance values. The increased strain-dependent resistance of stimulated nanotube network/polyurethane composite was demonstrated by monitoring vibration of tambour leather after a bead impact and finger flexion. Findings The results showed a tenfold composite resistance increase for the composite prepared from KMnO4 oxidized nanotubes, quantified by a so-called gauge factor, from a value of about 20 in comparison to the network prepared from pristine nanotubes. This is a substantial increase, which ranks the stimulated composite among materials with the highest electromechanical response. Originality/value The results in this paper are new and have not been published yet. The paper combines different ideas which are developed together. It presents a new concept of synergistic effect of CNT oxidation and application of pre-strain simulation. Oxidation and pre-strain increases by several times the sensitivity of the tested composites which are predetermined for use as strain sensors of various sizes and shapes.

Full textAbstract:
Under the green goals of the carbon peak and carbon neutrality, understanding how to develop the economy with high quality is an important issue facing regional development. Based on the years 2000, 2010, and 2020, this paper studies the industrial function connection path and economic network characteristics of the Hexi Corridor through an urban flow model, dominant flow analysis, modified gravity model, and social network analysis method, and puts forward an economic synergistic development model. It is of great significance to strengthen the urban connection in the Hexi Corridor and give full play to the overall competitive advantage. The results are as follows. (1) The overall function of the urban agglomeration is weak, the outward function of manufacturing is outstanding, the complementary network is highly complicated and evolving, and the environment and public service and tourism industry have apparent advantages. (2) The backbone correlation axes of the “three industries” show the characteristics of a closed triangular connection, dual-core linkage development, and multi-center multi-axis interaction. (3) The economic network has a greater agglomeration effect than diffusion effect, with prominent grouping characteristics, forming a network structure of “one man, three vices, and many nodes” and a significant spatial proximity effect. (4) Based on geographical proximity, the “one axis, four circles, multiple points, and multiple channels” synergistic development model, which breaks administrative barriers, becomes the endogenous driving force for the evolution of the economic network.

Full textAbstract:
Industrial Symbiosis (IS) is a systematic and collective (business) approach to optimizing the use of materials and energy among cross-sectoral industries in order to initiate and exhaust extended cascading systems; it is associated with (synergistic) environmental, technical, social, and economic benefits. For monitoring and controlling the development and progress of an IS system, an indicator system must be set up to standardize and assess the IS (sustainability) performance. This study aims to present a quantitative indicator system to enable the tracking of set sustainability targets of an IS system in Industrial Parks (IPs) for goal-directed IS management. The presented guiding framework encourages IP members in IS systems to set sustainability objectives and to evaluate and track their performance over time with a quantitative indicator system. In particular, established and (partly) internationally standardized methods—such as Material Flow Analysis (MFA), Material Flow Cost Accounting (MFCA), Social Network Analysis (SNA), and Life Cycle Assessment (LCA)—are used in order to place the indicator system on a solid and robust foundation and to adequately meet the multi-faceted sustainability perspectives in the form of a combinatorial application for deriving suitable quantitative indicators for all three (environmental, economic, social) dimensions of sustainability. The indicator system, once embedded in an Information Technology (IT)-supported IS tool, contributes crucially to the technology-enabled environment of IS systems, driving sustainability trajectories.

Full textAbstract:
Under the new development pattern, the penetration and integration between industries is becoming increasingly active, constantly promoting the rationalisation and heightening of the entire industrial structure and structuring new convergent industrial bodies. To explore the degree of integration between the digital economy and the logistics industry, this paper uses input-output models and social network analysis to empirically analyse the level of industrial integration between the core industries of China’s digital economy and the logistics industry during the period 2007–2017. The level of integration between the core industries of China’s digital economy and the logistics industry is measured, and its spatial and temporal characteristics are also measured and analysed. The analysis showed that (1) the degree of integration between the two industries is low, but with changes over time, the degree of integration will follow an upwards trend; the overall level of integration is increasing with the development of the core industries of the digital economy; the growth rate is significant, and developed regions have a clear advantage because of the intensity of integration. (2) The direction of industrial integration linkages is basically stable, with the pointing characteristics of adjacent provinces, and the spatial distribution shows a pattern of diffusion from the central region to the eastern and western regions. Overall, the integration shows an economic radiation effect, but there are large differences between the north and south. (3) It is easier for adjacent provinces to form the same cohesive subgroup in a network and develop together. At the same time, the integration network shows a clear pattern of marginal-semimmarginalization. The study enriches and improves the research status of China’s digital economy industry convergence, and provides theoretical support for the formulation of policies related to the synergistic development of China’s digital economy and logistics industry.

Due to the difference in pollutants discharged, along with heterogeneous abatement technology, the structural and model design of the economic production system needs to consider these differences. This study first proposes a network slacks-based model (SBM) to address the inefficiency of the production system after considering pollutant abatement technology heterogeneity for different kinds of pollutant. Then, we employ the model to study the inefficiency of the Chinese industrial production system, analyzing the inefficiency in the stages of economic production and pollutant treatment. Furthermore, the regional distribution of inefficiencies concerning SO2 (NOx) generation (emission) are discussed and compared. The results show that only the joint reduction of NOx in two sub-stages simultaneously is feasible, and the synergistic pollutant reductions seems limited.

In recent years, the urban rail transit network architecture has gradually grown, the contradiction between rail transit passenger flow and transport load has been deepening, and its carrying capacity has also been tested. Passenger flow risk has become the most important source of risk in rail transit. The key to restricting rail transit service quality is how to effectively monitor and manage rail transit passenger flow and provide accurate and convenient early warning to staff. In order to effectively manage the complex passenger flow scene, the premise is to distinguish the real-time state of its moving target. The time series data feature extraction and LSTM data fusion were used to analyze the traffic data sequence in the multilevel rail transit network model. The multilevel rail transit integration of the Internet of things is modeled by the method of data fusion. It can be seen from the experimental data that in the data fusion mode, the network comprehensive evaluation prediction value fitting effect can quickly converge, and the error rate is less than 4%. By comparing the mean square error (MSE) and mean absolute error (MAE) data of the traditional method and the experimental method used in this paper through two different datasets, it was understood that the MAE under the data fusion method was reduced by 8 compared with the traditional method, and the MSE was decreased by 33, indicating that this method can bring better simulation effect to the model. The improvement of the synergistic and complementary functional network and the acceleration of the efficient and convenient flow of elements are the inevitable results of the integration of multilayer rail transit in the metropolitan area.

In the context of China’s “double carbon” goal, pollution and carbon reduction is a consensus. As a demonstration area and model area for China’s development, how to take the lead in realizing the synergistic improvement of pollution and carbon reduction and embark on a green and low-carbon development path with Chinese characteristics is a common concern of the scientific community and the public. However, each city in Guangdong-Hong Kong-Macao Greater Bay Area (GBA) is different regarding resource endowment, energy structure, development conditions, and technical level. The efficiency, ability, and potential of pollution and carbon reduction must differ. The mission objectives, methods, and methods of promoting the “double carbon” work are also different. Only by considering it from the perspective of system collaboration can the “double carbon” work be safe and sustainable. The study proposes that we can, from the dynamic perspective of the production network and industrial transfer, integrate multi-source and multi-mode data and use a multi-scale evaluation method to analyze the multi-dimensional features and driving factors of the interaction effect of pollution and carbon reduction in GBA. The research results can help cities in GBA to understand their weak links in pollution and carbon reduction in a timely, comprehensive, and accurate manner. In addition, this study is conducive to providing decision-making reference for China to formulate regional synergistic effects.

Abstract To improve the thermal stability, ZF-GO (graphene oxide (GO) modified by zinc ferrite (ZF)) is prepared. In view of the anti-dripping function of ZF-GO and flame retardant effect of ammonium polyphosphate (APP), the influence of ZF-GO, APP, mixture of ZF-GO and APP on combustion performance, thermal stability and mechanical properties of polylactic acid (PLA) is investigated. Results show that the modification of GO by ZF significantly improves the residue of ZFGO by 34.7%. The char-forming capability and unique network structure of ZF-GO prevent the melt dripping of PLA. Although APP can increase the limiting oxygen index of PLA, there is still melt dripping. The combination of ZF-GO and APP improves the residual yield of 94PLA/3ZF-GO/3APP by 4.3 times relative to pure PLA, and the UL-94 level reaches V-0. The two additives show synergistic char-forming effect, and there is both physical carbonization and chemical carbonization. The incorporated fillers can decrease the total heat release (THR) of PLA composites. Specifically, the THR and peak value of heat release rate of 94PLA/3ZF-GO/3APP decrease by 21.2% and 53.9%, respectively. For the PLA/ZF-GO/APP system, plenty of residues and the anti-dripping network structure are key factors to get good flame retardancy. Addition of ZFGO and APP reduces the tensile strength, but the tensile elongation of the modified PLA composites is improved. 94PLA/ 3ZF-GO/3APP shows good integrated performance.

Purpose Industrial symbiosis (IS) is basically a synergistic association between two or more industries or businesses wherein the waste or by-product of one industry becomes the raw material or immediate material of another industry. IS is believed to bring in significant benefits to the organizations. Thus, the purpose of this paper is to evaluate the competitiveness attained through IS. Design/methodology/approach Analytic hierarchy process was adopted to analyze the various organizational competitiveness of IS implementation. The conceptual model was developed to understand the interrelationship between 14 outcomes and 5 organizational competitiveness which are identified from the literature review. The attainment of these five organizational competitiveness was evaluated by computing the global priority score of the outcomes. Findings The global priority score suggests that the organizational collaboration (0.19) is the important output. Further, collective learning and growth (44 percent) have been identified as the important competitiveness attained through the implementation of IS. Practical implications The relationship matrix developed can be used by the practicing managers/researchers to understand the various interactions. Thus, systematic decision making and guidance for future implementation studies will be ensured. Originality/value In the past, few authors discussed the conceptualization of IS; however, the impact of IS on the organizational performance was not extensively studied. Therefore, a conceptual model was proposed to analyze the attainment of various competitiveness through the participation of industrial symbiosis network. Further, based on the computed scores, the relationship matrix developed between outcomes and organizational competitiveness is one of the significant contributions of this work.

Purpose: The purpose of this study is to develop the theory of regional economics in the context of the cluster organization of its petrochemical complex.
Methodology: The research methodology includes the use of cluster analysis and network planning of performance indicators of the petrochemical complex of the Republic of Tatarstan.
Findings: It was found that over seven years of the existence of petrochemical cluster in the Republic of Tatarstan, no synergistic effects were achieved because of its activities. At the same time, significant financial resources were allocated to the cluster organization of petrochemical complex in this region and an administrative apparatus was created. The very concept of cluster development of the region in science and practice has long proved its viability in many countries, such as the Republic of Tatarstan since Michael Porter. This is because the Soviet times is provided with a highly developed industrial base and inexpensive labor in the field of petrochemical technologies, and the training of professional specialists in the region is provided by a concentration of higher education institutions.
Implications: The economic and mathematical approaches used in this study enable it to single out the forms of activity in the cluster that enable it to increase its efficiency to the greatest extent with the least costs. Comprehensive network planning of cluster innovation based on graphical and potential methods presented in the study provide competitive advantages to small- and medium-sized companies.

The agricultural sector is the driver and “point of growth” of the national economy of Ukraine. Agriculture accounts for an average of 16% of gross value added in some regions and plays a key role in ensuring food security. However, the current conditions of martial law in Ukraine have led to problems in the organization of logistics activities of enterprises of the agro-industrial complex as a result of non-fulfillment of the terms of contracts; the emergence of risks of disruption of the sowing campaign; decrease in final harvest indicators and the level of food security; decrease in the volume of export deliveries of agricultural products; disruption of food supply chains; lack of adequate financing and logistics infrastructure facilities; insufficient effective use of marketing management tools and a network approach in the process of distributing agricultural products to the final consumer; increase in transaction costs, etc. Therefore, the purpose of this article is to study modern challenges, threats, trends and barriers in the organization of international logistics activities of agrarian enterprises in the conditions of war. The article theoretically summarizes and systematizes conceptual approaches to determining the economic essence of the concepts of “foreign economic activity” and “international logistics”. A statistical analysis of the main indicators of the development of foreign economic activity of enterprises of the agro-industrial complex of Ukraine in the pre-war period was performed. Barriers that inhibit the effective organization of international logistics activities of agrarian enterprises in wartime have been identified. Priority directions for eliminating existing barriers that prevent the organization of foreign economic logistics activities are proposed, the essence of which is to activate network interaction and partnership relations based on the creation of agrocluster structures; unification of small farms for the proper execution of contracts, as well as joint activity in the agrarian sphere of two or more companies and different groups of stakeholders to achieve a common goal and a synergistic effect.

ABSTRACTHigh-cell-density fermentation for industrial production of chemicals can impose numerous stresses on cells due to high substrate, product, and by-product concentrations; high osmolarity; reactive oxygen species; and elevated temperatures. There is a need to develop platform strains of industrial microorganisms that are more tolerant toward these typical processing conditions. In this study, the growth of six industrially relevant strains ofEscherichia coliwas characterized under eight stress conditions representative of fed-batch fermentation, and strains W and BL21(DE3) were selected as platforms for transposon (Tn) mutagenesis due to favorable resistance characteristics. Selection experiments, followed by either targeted or genome-wide next-generation-sequencing-based Tn insertion site determination, were performed to identify mutants with improved growth properties under a subset of three stress conditions and two combinations of individual stresses. A subset of the identified loss-of-function mutants were selected for a combinatorial approach, where strains with combinations of two and three gene deletions were systematically constructed and tested for single and multistress resistance. These approaches allowed identification of (i) strain-background-specific stress resistance phenotypes, (ii) novel gene deletion mutants inE. colithat confer single and multistress resistance in a strain-background-dependent manner, and (iii) synergistic effects of multiple gene deletions that confer improved resistance over single deletions. The results of this study underscore the suboptimality and strain-specific variability of the genetic network regulating growth under stressful conditions and suggest that further exploration of the combinatorial gene deletion space in multiple strain backgrounds is needed for optimizing strains for microbial bioprocessing applications.

In this paper, a flame-retardant, UV-cured coating was prepared on the fiber composites’ (FC) surface via a thiol-ene click reaction using pentaerythritol tetra(3-mercaptopropionate) (PETMP), triallyl cyanurate (TAC), and 2-hydroxyethyl methacrylate phosphate (PM-2). The synergistic effectiveness of phosphorus (P), nitrogen (N), and sulfur (S) was studied in detail by changing the proportion of these reactants. Sample S4(N3P2)6, with a molar ratio of N and P elements of 3:2, and the thiol and vinyl groups of 4:6 had the highest LOI value (28.6%) and was self-extinguishing in the horizontal combustion test. It had the lowest peak heat release rate (PHRR) value (279.25 kW/m2) and total smoke production (2.18 m2). Moreover, the thermogravimetric analysis (TG) showed that the decomposition process of the coated composites was delayed. The conversion rate of the double bond and the thiol of S4(N3P2)6 was 100% and 92.0%, respectively, which showed that the cross-linked network structure was successfully formed. The tensile strength and the flexural strength of coated composites improved, and the transparency of the coating can reach 90%. These characteristics showed that the UV-cured coatings could be used in industrial production to effectively prevent fires.

Introduction. Modern post-coronavirus conditions of economic development indicate that one of the strategic prospects for sustainable development of Ukraine's regions is the further spread of the progressive global trend “Industry 4.0”, including industrial clusters. Clusters, as new forms of spatial organization of production, characterized by powerful mobilization opportunities and high competitiveness in global and national markets are recognized as important elements in the development of regional innovation ecosystems. They play an important role in promoting the shift and development of industrial parks. Therefore, cluster issues are relevant in all its manifestations, including at the level of research on the genesis of cluster theory from its inception to the formation of the modern (“classical”) variant. Purpose. The aim of the article is to analyse the genesis and evolution of the theory of economic clusters from the XVIII century (stage of origin, which is associated with the ideas of J. Tunen) and the 90s of XX century (emergence of modern cluster theory – M. Porter). Research methods. The article used the historical method, logical-abstract, methods of analysis and synthesis. Results. The article emphasizes that the concept of “cluster” is inherent not only in economics. A thorough analysis of economic scientific sources gives grounds to claim that the first developments in cluster theory can be traced in the works of economists of various fields and schools. However, most researchers believe that the founders of cluster theory were J. Tunen and A. Marshall. In its modern form, cluster theory began to take shape in the 80's and 90's of the XX century. The ancestor of cluster theory is considered to be the famous American scientist M. Porter. It was found that M. Porter in his research uses several approaches to the interpretation of the concept of “cluster” – geographical, network, synergistic and so on. It is established that the essence and content of cluster theory M. Porter reveals through the model “Diamond”, which includes four interrelated components: factor conditions; state of demand; related and supporting industries (clusters); strategy, structure and rivalry of the firm. It is determined that the development of industrial clusters (according to M. Porter) is significantly influenced by the public and private sectors, social structure, initiatives related to the activities of the industrial cluster. The advantages and disadvantages of P. Porter's cluster theory are determined and the model of an industrial cluster is developed. Conclusion. The analysis shows that cluster ideas among scientists appear in almost all economic fields and schools, regardless of the historical period of their existence. The advantages of this form of association were known in the early twentieth century. It is established that the founder of modern cluster theory M. Porter during its creation on the basis of the concept of competitive advantage, generated different approaches and theoretical achievements of economic scientific thought (primarily spatial, innovative and network scientific theories). An important aspect of M. Porter's industrial cluster model is the synergetic effect, based on which industrial clusters through economic means (productivity, innovation, new business creation), affect competitiveness, which ultimately ensures the development of the state economy.

Purpose The purpose of this paper is to focus on the operation strategy of high-performance alliance portfolios by analyzing the effect of alliance portfolios on the performance of focal firms, using post-structuralism of social network theory and contingency theory. In detail, this paper refines alliance portfolios into three dimensions, and studies the moderating role of context on the relation between alliance portfolios and firm performance. Design/methodology/approach The empirical study was carried out with second-hand data gathered from Internal Revenue Service. In total, this paper gathered data from 506 focal firms in Zhejiang Province from 2001 to 2010 as the sample to test the hypotheses. Findings Based on the empirical results, the authors find the positive effect of relational dimension (weak alliance portfolios) and partner dimension (the diversity of partners) on performance. The effect of the former will become weaker with the increasing environmental dynamic, while the effect of the latter will become stronger. However, the structural dimension (alliance portfolios size) and relational dimension (new partners) have the negative effect on performance. And the negative effect will become stronger under high environmental dynamic. Moreover, the negative effect of non-local partners on performance becomes stronger when the environmental dynamic is high. Research limitations/implications The paper reveals that with the industry transformation caused by “internet +,” companies have been required go beyond traditional dyadic alliance management perspective. That is to say, individual alliance relationship should be seen as a part of a much broader picture of alliance portfolio. As such, the framework may help companies to manage their alliance portfolios by matching high-performance alliance portfolios to the external environment to produce a synergistic effect (Lea et al., 2006; Tritos et al., 2013; Keith et al., 2014) taking the characteristics of the configuration of alliance portfolios into consideration. Originality/value The paper presents a model that explains the effect of three dimensions of alliance portfolios on the performance of focal firms in different contexts through empirical study. This paper also integrates post-structuralism of social network theory and contingency theory to enable the understanding on the configuration of alliance portfolios.

The study is devoted to defining the essential content of integration as a process, revealing the features of integrated associations in terms of their structure, taking into account the specifics of agro-industrial production. The theoretical basis of the analysis was the understanding of the economic entities’ integration as a multi-level process of systemic transformation, which implies qualitative changes at each stage of integration growth. A concepts differentiation of the “subject” and “subjective factor” is presented based on the meaning understanding of the subject as a structure element of integrated associations. It is recognized that the economic entity acts as a carrier of certain properties and potentials, in particular – integrative, and subjective factor – the action of the subjects aimed at achieving a specific goal. In order to provide a methodological apparatus for qualitative systematic analysis of potential types, forms and methods of forming integrated associations of agricultural production enterprises, taking into account the specific objectives of the association, a typology of integration was proposed, which included decentralized integration, partially centralized integration and centralized integration. The levels of economic entities integration according to the elements that are part of the integration group are highlighted: the level of enterprise interaction, the level of corporate interaction, the level of industry interaction. Structural peculiarities of integrated structures functioning of agroindustrial production on cluster bases (based on rationalization of transformations in the field of interbranch exchange, structural reorganization and innovation-investment modernization of the enterprises-members of the unions, improvement of the level of economic efficiency and competitiveness due to obtaining synergistic effects of economic interaction) and on the basis of strategic alliances are disclosed. Network connections in the cluster structures development with an emphasis on the integration degree of these connections subjects are explored. The strategic management imperative of the integration structural parameters in the agro-food complex is formulated – the corporate structures organization in the form of industrial and social clusters, which is the nucleus around which suppliers, enterprises and consumers of other industries are closely connected with the cluster core of the territorial-industrial complex. Keywords: agro-industry, agrarian enterprises, integrated alliances, clusters, strategic alliances.

Full textAbstract:
Water is an indispensable strategic resource for biological and social development. The problem of oily wastewater pollution originating from oil spillages, industrial discharge and domestic oil pollution has become an extremely serious international challenge. At present, numerous superwetting materials have been applied to effectively separate oil and water. However, most of these materials are difficult to scale and their large–scale application is limited by cost and environmental protection. Herein, a simple, environmentally friendly strategy including sol–gel, freeze–drying and surface hydrophobic modification is presented to fabricate a bamboo cellulose foam with special wetting characteristics. The bamboo cellulose foam is superhydrophobic, with a water contact angle of 160°, and it has the superoleophilic property of instantaneous oil absorption. Owing to the synergistic effect of the three–dimensional network structure of the superhydrophobic bamboo cellulose foam and its hydrophobic composition, it has an excellent oil–absorption performance of 11.5 g/g~37.5 g/g for various types of oil, as well as good recyclability, with an oil (1,2–dichloroethane) absorption capacity of up to 31.5 g/g after 10 cycles. In addition, the prepared cellulose–based foam exhibits an outstanding performance in terms of acid and alkali corrosion resistance. Importantly, owing to bamboo cellulose being a biodegradable, low–cost, natural polymer material that can be easily modified, superhydrophobic/superoleophilic bamboo cellulose foam has great application potential in the field of oily wastewater treatment.

Purpose The purpose of this study is to present a highly stretchable and flexible strain sensor with simple and low cost of fabrication process and excellent dynamic characteristics, which make it suitable for human motion monitoring under large strain and high frequency. Design/methodology/approach The strain sensor was fabricated using the rubber/latex polymer as elastic carrier and single-walled carbon nanotubes (SWCNTs)/carbon black (CB) as a synergistic conductive network. The rubber/latex polymer was pre-treated in naphtha and then soaked in SWCNTs/CB/silicon rubber composite solution. The strain sensing and other performance of the sensor were measured and human motion tracking applications were tried. Findings These strain sensors based on aforementioned materials display high stretchability (500 per cent), excellent flexibility, fast response (approximately 45 ms), low creep (3.1 per cent at 100 per cent strain), temperature and humidity independence, superior stability and reproducibility during approximately 5,000 stretch/release cycles. Furthermore, the authors used these composites as human motion sensors, effectively monitoring joint motion, indicating that the stretchable strain sensor based on the rubber/latex polymer and the synergetic effects of mixed SWCNTs and CB could have promising applications in flexible and wearable devices for human motion tracking. Originality/value This paper presents a low-cost and a new type of strain sensor with excellent performance that can open up new fields of applications in flexible, stretchable and wearable electronics, especially in human motion tracking applications where very large strain should be accommodated by the strain sensor.

Full textAbstract:
The article aims to study the management of the innovative economy in the context of sustainable development within an institutional and matrix clusterization model in the context of adaptive human resource management, the digitalization of the agricultural and food sphere and adaptation to the COVID-19 pandemic. Methods. The following special methods of scientific cognition were used in the research process: historical-logical method; method of systematization, classification and theoretical generalization; method of institutional analysis; method of system analysis; method of logical analysis and synthesis; method of graphic analysis. Results. The evolution of the effect of collaboration and achievement of synergy within clusters under different types of economic systems has been determined. It is shown that in a post-industrial economy there is a very strong effect of intra-cluster collaboration, which is due to the dominance of a super competitive environment and mutually beneficial cooperation between government, business and science. The formation of institutional and matrix clusterization in the system of the innovation economy is proposed. It is shown that the effectiveness of institutional and matrix clusterization is ensured by a high degree of its stakeholder communicativeness. Practical contribution. The directions and ways of development of clustering of innovative entrepreneurship, combining the characteristics of effective network cooperation with the participation of large leading enterprises in the form of cluster models "wheel and spokes", "satellite" cluster, provide an opportunity to plan at the macro, meso and micro levels innovation clusters taking into account the strategic priorities of economic development. Prospects for further research. Technological, human, material and information exchange with the changing external environment is constantly taking place in the innovation cluster. Such environment is characterized by a set of economic entities with which innovation, material and information interchange (innovation, products, personnel, services, finance, marketing communications, etc.) takes place constantly. The main feature of institutional and matrix clusterization is the emergence of synergistic effect and, as a consequence, the formation of mutually beneficial cooperation in the network system.

Full textAbstract:
In the era of tourism 4.0, the subjective preferences and experiences of tourists directly affects the future development of scenic spots. Among them, 5A scenic spots represent China’s world-class boutique tourist scenic ranking, which pays more attention to humanization and detailing, and better reflect tourists’ general psychological demand for tourist attractions. Therefore, it becomes an important scientific issue to explore the spatial and temporal characteristics of 5A tourists’ preferences and their deeper reasons. China’s eastern coastal provinces have played a very important role in promoting regional tourism culture, promoting regional economic development, and building a strong coastal province. Taking Jiangsu as an example, this study introduces the standard deviation ellipse and kernel density estimation to explore the characteristics and trends of tourist preference clustering in 5A scenic spots and their internal and external driving mechanisms from 2012–2021, which is based on a new perspective of geotemporal dynamic analysis. The empirical results show that: (1) the network attention of 5A scenic spots in Jiangsu generally showed a “barb-type” trend in 2012–2021, the highest network attention is concentrated in April and October, accounting for 82%, and tourists pay the most attention to cultural relics scenic spots, peaking on Sunday; (2) the tourist preference for 5A scenic spots in Jiangsu shows a relative clustering distribution pattern in general, with a slightly higher clustering trend in the northwest-southeast direction than in the northeast-southwest direction. Furthermore, the nucleus of the density values range from 0 to 115.43, showing the spatial pattern of “one belt and two cores”; (3) the internal driving factors include the types, the culture nature, the characteristics nature, the spatial proximity, and the infrastructure of scenic spots, and the external driving factors include geographical location, industrial development policy, climate comfort, economic development level, traffic accessibility, and the impact of COVID-19 epidemic. On this basis, this study puts forward feasible suggestions for improving scenic area management and increasing the reception capacity, so as to provide fine scientific guidelines for the high-quality development of 5A scenic spots in Jiangsu and provide reference for further enhancing the attractiveness of 5A scenic spots and their synergistic development in the eastern coastal provinces.

Full textAbstract:
In this study, the structure, electrical and thermal properties of ten polymer compositions based on polylactic acid (PLA), low-cost industrial graphene nanoplates (GNP) and multi-walled carbon nanotubes (MWCNT) in mono-filler PLA/MWCNT and PLA/GNP systems with 0–6 wt.% filler content were investigated. Filler dispersion was further improved by combining these two carbon nanofillers with different geometric shapes and aspect ratios in hybrid bi-filler nanocomposites. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy exhibited uniform dispersion of nanoparticles in a polymer matrix. The obtained results have shown that for the mono-filler systems with MWCNT or GNP, the electrical conductivity increased with decades. Moreover, a small synergistic effect was observed in the GNP/MWCNT/PLA bi-filler hybrid composites when combining GNP and CNT at a ratio of 3% GNP/3% CNT and 1.5% GNP:4.5% CNT, showing higher electrical conductivity with respect to the systems incorporating individual CNTs and GNPs at the same overall filler concentration. This improvement was attributed to the interaction between CNTs and GNPs limiting GNP aggregation and bridging adjacent graphene platelets thus, forming a more efficient network. Thermal conductivity increases with higher filler content; this effect was more pronounced for the mono-filler composites based on PLA and GNP due to the ability of graphene to better transfer the heat. Morphological analysis carried out by electron microscopy (SEM, TEM) and Raman indicated that the nanocomposites present smaller and more homogeneous filler aggregates. The well-dispersed nanofillers also lead to a microstructure which is able to better enhance the electron and heat transfer and maximize the electrical and thermal properties. The obtained composites are suitable for the production of a multifunctional filament with improved electrical and thermal properties for different fused deposition modelling (FDM) 3D printing applications and also present a low production cost, which could potentially increase the competitiveness of this promising market niche.

Full textAbstract:
The new pattern of “dual circulation” is a new development model for China to seek mutual promotion between international and domestic markets in the new era. In this context, this paper explores the synergistic relationship between two-way FDI and its impact mechanism on the improvement of China’s manufacturing innovation capability. By taking 27 segments of the Chinese manufacturing industry as data samples from 2003 to 2018, we use the Granger cause, orthogonalized impulse response function, and physical capacity coupling system to verify the two-way FDI synergistic development relationship in the Chinese manufacturing industry and measure its degree of synergy. In addition, we empirically explore the mediating role of industrial structure upgrading in the impact of two-way FDI synergistic development on innovation capability in the Chinese manufacturing industry, and further analyze the industrial heterogeneity of this mediating role among labor-intensive, capital-intensive, and technology-intensive manufacturing segments. The study finds that firstly, there are different degrees of synergistic development in the Chinese manufacturing segments, and this synergistic development significantly contributes to the innovation capability and industrial structure upgrading of the Chinese manufacturing industry. Secondly, industrial structure upgrading of the Chinese manufacturing industry plays an essential mediating effect in the innovation-driving process of the two-way FDI synergistic development, and the mediating effect shows significant industrial heterogeneity. More specifically, the mediating effects in labor-intensive and technology-intensive industries are significantly positive, and the mediating effect in technology-intensive industries is more prominent. However, the mediating effect in capital-intensive industries is significantly negative. The paper provides empirical evidence to clarify the innovation-driving mechanism of the two-way FDI synergistic development in China’s manufacturing industry from the perspective of the new development pattern of “dual circulation” and provides valuable references for research in related fields.

In the context of the world economy, air transport today, among other characteristics, is characterized by high technological complexity of vehicles, increasing the safety of air transport, strengthening measures to protect aviation from acts of unlawful interference and development of modern multimodal transport technologies and infrastructure for various modes of transport. Due to the global trend, unmanned aerial vehicles have become widespread in various areas and sectors of the world economy. Meanwhile, the issue of energy security as a component of aviation security at airfields and specialized enterprises in their operation, storage and maintenance remains unresolved. The problem of this work is the synthesis of the method of determining the potential of dispersed energy sources in aviation enterprises. Combining the parallel operation of dispersed generation and network will give a synergistic effect - the emergence of new properties that were not in the components, which is manifested, in particular, in increasing factors influencing energy performance, irregularity of the total load schedule of integrated systems, reducing its unevenness in daily, weekly and seasonal sections, reducing the dependence of the frequency of electric current on power balance fluctuations. In previous studies, the authors justify the positive effect of the introduction of sources of dispersed generation in industrial enterprises, namely modularity, reliability, local governance, reducing the negative impact on the environment and short start-up period. Given the complexity of the technological process and the specifics of the operation of electrical equipment of aviation enterprises, an urgent scientific and practical task is to develop a method for determining the potential of dispersed energy sources in these enterprises. To determine the potential of sources of dispersed generation in aviation enterprises, it is necessary to have as complete and clear data on electricity supply and power consumption of electrical equipment of these enterprises during the day, as well as data on electricity consumption in the power grid, operation and load consumption. At aviation enterprises, the introduction of dispersed generation based on renewable energy sources into the general structure of power supply systems is relevant and possible. The proposed method of determining the potential of dispersed energy sources in the conditions of aviation enterprises will allow to effectively implement dispersed generation in the power supply structure of aviation enterprises.

Topicality. Current high socioeconomic (public) request for recreational and tourist services and the inadequate use of available natural resources in Ukraine as recreational make it necessary to find directions for diversification of their rational use for expanding recreational and tourist activities and related species.Aim and tasks. Purpose of the article is to determine the conceptual approaches to the diversification processes development in the use of natural resources around the territory of Kuyalnitsky estuary, that are aimed at revealing its potential and expansion of business activities of enterprises and districts in general.Research results. According to the analysis of financial and economic indicators of administrative units (Bilyaivskyi, Ivanivsky and Limansky districts), adjacent to the Kuyalnitsky estuary, and the aim, the authors conclude that the traditional use of natural resources in agriculture and industry does not provide the proper level of socio-economic development of the districts and they are not financially self-sufficient. Consequently, the economic activity in the Kuyalnitsky estuary basin is focused on agriculture and industrial production, but this territory diversification of the natural resource potential use in the direction of recreational and tourist activity as an alternative to existing types of production is required. The processes of diversification will consist in the production of environmentally friendly products and services to meet the needs of recreational activities, as recreational activity will contribute to increasing demand for them. To start diversification of economic activities types, which will provide synergistic effect and increase economic indicators of the development of areas around the Kuyalnitsky estuary is proposed. Among the areas of natural resources diversification of the estuary, it is proposed to consider the development of a network of sanatorium and resort establishments, enterprises of cosmetic products creation, as well as beauty salons with the use of the resource potential of the Kuyalnitsky estuary (brine, mud, salt, blue clay, phyto-preparations).Conclusions. The districts located around the Kuyalnitsky estuary have rich recreational natural resources, but do not use them fully in economic activity. In fact, there is only one sanatorium that uses mud and peloids of the estuary. The budgets of these districts do not cover their expenditures and receive subsidies from the regional budget, and the lack of proper implementation of the environmental legislation has led to the almost critical environmental situation of the Kuyalnitsky estuary. In order to improve the current situation, the authors propose to direct economic activities diversification processes of economic entities for the tourism development, in particular, rural, green, ecological, cognitive with the provision of medical services on the basis of unique mud of the estuary, taking into account ecosystem and polyfunctional approaches that will ensure the use , preservation and protection of a unique natural object.

Full textAbstract:
Industrialization is indispensable for socio-economic development but poses far-reaching implications for resources and the environment. Consequently, industrial symbiosis-based collaborations are gaining recognition as a viable strategy to manage resource consumption for mitigating environmental distress. However, these types of synergistic collaborations are more prevalent in developed regions and are linked to larger-sized industries. Admittedly, such collaborative partnerships are less focused in developing regions and small- to medium-size enterprises (SMEs). This calls for discovering the potentials for synergistic partnerships among the small and medium scaled industrial entities in developing economies. Therefore, the study was designed to identify, assess and explore the prospects of symbiotic collaborations among SMEs in Pakistan. Moreover, the inputs are equally relevant for developing and expanding such productive associations in developing regions. Data regarding inputs and outputs was collected from sixty-one (61) SMEs through field survey during the year 2019. It was processed and analyzed to uncover existing and potential synergies among SMEs. The significant findings transpired that the majority of collaborative linkages are bilateral and are driven to maximize economic gains. However, informal networks of recyclers and absence of a stringent regulatory regime are the ground realities in developing/transforming economies. These factors symptomatically interfere with the process of formal/informal exchanges between and among firms. Furthermore, it was observed that the lack of awareness and impulsiveness of SMEs, as well as the inconsistent supply of by-products, act as barriers for such partnerships in developing countries. It calls for proactive engagements and facilitations from the state institutions through policy instruments. The study addresses a broad audience including industrialists, investors, policy makers and researchers engaged in IS studies. Moreover, the inputs will provide impetus for stimulating eco-industrial progress in developing regions such as Pakistan.

Promoting the initiative and subjectivity of the two main bodies of schools and enterprises, as well as fully exploiting their synergy in practice, is a necessary prerequisite for reflecting the benefits of school-enterprise integration, and without it, China’s vocational education cannot improve the quality of professional and technical personnel training. Simultaneously, it allows for high-level economic and social development. This is also the focus and challenge of current vocational and technical education reform and innovation. We discovered that the integration of industry and education, as well as school-enterprise cooperation, has made significant progress in City C’s higher vocational colleges through questionnaire surveys and on-site interviews: the cooperation mechanism has been steadily established and innovated, the talent joint training model is diverse; the level of cooperation between the two parties has been continuously improved; the benefits of enterprise cooperation are complementary, and s The current situation is “schools are hot and enterprises are hot,” and both supply and demand are booming, contrary to the empirical view that the education industry integrates “schools are hot and enterprises are cold.” The engineering talent training industry-education integration collaboration model is to establish and combine multiple case studies to illustrate its application scenarios, and then propose the characteristics of the collaboration model and the level analysis of the collaboration elements based on different systems, dynamics, and dynamic training models. This study collects data through questionnaire surveys and investigates the synergistic elements using the fs QCA empirical analysis method. These synergistic elements can help the integration project be more effective. Reproducible guidance is provided by various types of integration projects. Finally, in light of the current state of talent training in the integration of production and education, this research suggests three countermeasures: government optimization of top-level design, hierarchical implementation of the collaborative main model, and project implementation scope to coordinate school and enterprise path selection.

Civil infrastructures such as bridges, buildings, and pipelines ensure society's economic and industrial prosperity. Specifically, pipe networks assure the transportation of primary commodities such as water, oil, and natural gas. The quantitative and early detection of defects in pipes is critical in order to avoid severe consequences. As a result of high-profile accidents and economic downturn, research and development in the area of pipeline inspection has focused mainly on gas and oil pipelines. Due to the low cost of water, the development of nondestructive inspection (NDI) and structural health monitoring (SHM) technologies for fresh water mains and sewers has received the least attention. Moreover, the technical challenges associated with the practical deployment of monitoring system demand synergistic interaction across several disciplines, which may limit the transition from laboratory to real structures. This paper presents an overview of the most used NDI/SHM technologies for freshwater pipes and sewers. The challenges that said infrastructures pose with respect to oil and natural gas pipeline networks will be discussed. Finally, the methodologies that can be translated into SHM approaches are highlighted.

We are very pleased and honored to have an opportunity to publish a new journal the "International Journal of Advanced Computational Intelligence" (JACI). The JACI is a new, bimonthly journal covering the field of computer science. This journal focuses on advanced computational intelligence, including the synergetic integration of neural networks, fuzzy logic and evolutionary computations, in order to assist in fostering the application of intelligent systems to industry. This new field is called computational intelligence or soft computing. It has already been studied by many researchers, but no single, integrated journal exists anywhere in the world. This new journal gives readers the state of art of the theory and application of Advanced Computational Intelligence. The Topics include, but are not limited to: Fuzzy Logic, Neural Networks, GA and Evolutionary Computation, Hybrid Systems, Network Systems, Multimedia, the Human Interface, Biologically-Inspired Evolutionary Systems, Artificial Life, Chaos, Fractal, Wavelet Analysis, Scientific Applications and Industrial Applications. The journal, JACI, is supported by many researchers and scientific organizations, e.g., the International Fuzzy Systems Association (IFSA), the Japan Society of Fuzzy Theory and Systems (SOFT), the Brazilian Society of Automatics (SBA) and The Society of Instrument and Control Engineers (SICE), and we are currently negotiating with the John von Neumann Computer Society (in Hungary). Our policy is to have world-wide communication with many societies and researchers in this field. We would appreciate it if those organizations and people who have an interest in co-sponsorship or have proposals for special issues in this journal, as well as paper submissions, could contact us. Finally our special thanks go to the editorial office of Fuji Technology Press Ltd., especially to its president, Mr. K. Hayashi, and to the editor, Mr. Y. Inoue, for their efforts in publishing this new journal. Lotti A. Zadeh The publication of the International Journal of Advanced Computational Intelligence (JACI) is an important milestone in the advancement of our understanding of how intelligent systems can be conceived, designed, built, and deployed. When one first hears of computational intelligence, a question that naturally arises is: What is the difference, if any, between computational intelligence (CI) and artificial intelligence (AI)? As one who has witnessed the births of both AI and CI, I should like to suggest an answer. As a branch of science and technology, artificial intelligence was born about four decades ago. From the outset, AI was based on classical logic and symbol manipulation. Numerical computations were not welcomed and probabilistic techniques were proscribed. Mainstream AI continued to evolve in this spirit, with symbol manipulation still occupying the center of the stage, but not to the degree that it did in the past. Today, probabilistic techniques and neurocomputing are not unwelcome, but the focus is on distributed intelligence, agents, man-machine interfaces, and networking. With the passage of time, it became increasing clear that symbol manipulation is quite limited in its ability to serve as a foundation for the design of intelligent systems, especially in the realms of robotics, computer vision, motion planning, speech recognition, handwriting recognition, fault diagnosis, planning, and related fields. The inability of mainstream AI to live up to expectations in these application areas has led in the mid-eighties to feelings of disenchantment and widespread questioning of the effectiveness of AI's armamentarium. It was at this point that the name computational intelligence was employed by Professor Nick Cercone of Simon Fraser University in British Columbia to start a new journal named Computational Intelligence -a journal that was, and still is, intended to provide a broader conceptual framework for the conception and design of intelligent systems than was provided by mainstream AI. Another important development took place. The concept of soft computing (SC) was introduced in 1990-91 to describe an association of computing methodologies centering on fuzzy logic (FL), neurocomputing (NC), genetic (or evolutionary) computing (GC), and probabilistic computing (PC). In essence, soft computing differs from traditional hard computing in that it is tolerant of imprecision, uncertainty and partial truth. The basic guiding principle of SC is: Exploit the tolerance for imprecision, uncertainty, and partial truth to achieve tractability, robustness, low solution cost, and better rapport with reality. More recently, the concept of computational intelligence had reemerged with a meaning that is substantially different from that which it had in the past. More specifically, in its new sense, CI, like AI, is concerned with the conception, design, and deployment of intelligent systems. However, unlike mainstream AI, CI methodology is based not on predicate logic and symbol manipulation but on the methodologies of soft computing and, more particularly, on fuzzy logic, neurocomputing, genetic(evolutionary) computing, and probabilistic computing. In this sense, computational intelligence and soft computing are closely linked but not identical. In basic ways, the importance of computational intelligence derives in large measure from the effectiveness of the techniques of fuzzy logic, neurocomputing, genetic (evolutionary) computing, and probabilistic computing in the conception and design of information/intelligent systems, as defined in the statements of the aims and scope of the new journal of Advanced Computational Intelligence. There is one important aspect of both computational intelligence and soft computing that should be stressed. The methodologies which lie at the center of CI and SC, namely, FL, NC, genetic (evolutionary) computing, and PC are for the most part complementary and synergistic, rather than competitive. Thus, in many applications, the effectiveness of FL, NC, GC, and PC can be enhanced by employing them in combination, rather than in isolation. Intelligent systems in which FL, NC, GC, and PC are used in combination are frequently referred to as hybrid intelligent systems. Such systems are likely to become the norm in the not distant future. The ubiquity of hybrid intelligent systems is likely to have a profound impact on the ways in which information/intelligent systems are conceived, designed, built, and interacted with. At this juncture, the most visible hybrid intelligent systems are so-called neurofuzzy systems, which are for the most part fuzzy-rule-based systems in which neural network techniques are employed for system identification, rule induction, and tuning. The concept of neurofuzzy systems was originated by Japanese scientists and engineers in the late eighties, and in recent years has found a wide variety of applications, especially in the realms of industrial control, consumer products, and financial engineering. Today, we are beginning to see a widening of the range of applications of computational intelligence centered on the use of neurofuzzy, fuzzy-genetic, neurogenetic, neurochaotic and neuro-fuzzy-genetic systems. The editors-in-chief of Advanced Computational Intelligence, Professors Fukuda and Hirota, have played and are continuing to play majors roles both nationally and internationally in the development of fuzzy logic, soft computing, and computational intelligence. They deserve our thanks and congratulations for conceiving the International Journal of Advanced Computational Intelligence and making it a reality. International in both spirit and practice, JACI is certain to make a major contribution in the years ahead to the advancement of the science and technology of man-made information/intelligence systems -- systems that are at the center of the information revolution, which is having a profound impact on the ways in which we live, communicate, and interact with the real world.

This paper uses Northwest China as an example to present an in-depth study and analysis of river valley cities’ spatial structure and city form in the context of artificial intelligence. The paper focuses on alleviating the “core-edge” spatial structure locking effect, achieving the “industry-space” scale effect and cooperation, solving the problem of endogenous dynamics to promote regional and urban development, and promoting various main functional areas based on the derivation discussion and spatial growth model selection. The study focuses on the exploration of paths to alleviate the “core-edge” spatial structure’s locking effect, realize the scale effect and cooperation ability of “industry-space,” solve the problem of endogenous power to promote regional and urban development, and promote the new urbanization path of different main functional areas based on the discussion and spatial growth mode selection. We measure the evolution characteristics of industrial and spatial elements and the level of intersystem synergistic development to address the spatial growth and industrial transformation of the northwest region urban agglomeration in the special development period, discover the defects of the northwest China urban agglomeration’s spatial growth, and select the appropriate spatial growth model in the foreseeable spatial and temporal scope. The new city spatial form in the northwest region, which strengthens regional characteristics, is the spatial form combined with the new city plan form in two dimensions. This paper investigates the relationship between regional characteristics and urban spatial carriers by developing spatial planning design ideas and methods that reflect the regional characteristics of new cities in the northwest region, in order to improve the spatial quality of new cities in the northwest region and their sense of belonging to the city, provide a new spatial expansion idea for small cities in river valleys in the Qinling Mountains of southern Shaanxi, and enrich the spatial quality of new cities in the northwest region.

Purpose This paper aims to examine how various academic disciplines shape the field of event portfolio management. Given the complex nature of portfolios comprising different genres that are studied separately from their respective disciplinary realms, the academic event portfolio landscape remains fragmented. This is against the nature of portfolios, which requires inter-disciplinarity and novel integration of genres, stakeholders and perspectives. Design/methodology/approach Based on a scoping literature review, this conceptual paper sets up a common ground for the academic study and industrial development of event portfolio management. Findings A comprehensive view of event portfolio literature across disciplines reveals its hypostasis as a compound transdisciplinary field. The authors suggest a set of foundational premises whereby they identify 22 principal thematic areas that comprise this emerging field. Practical implications The establishment of event portfolio management as a distinct field will help in the osmosis and diffusion of new ideas, models and best practices to run and leverage portfolios. The portfolio perspective highlights the need for cohesive learning to design comprehensive systems of events, implement joint strategies, solidify social networks, coordinate multiple stakeholders and develop methods of holistic evaluation. Originality/value By examining comprehensively event portfolio management as a transdisciplinary field, the authors have been able to identify principal research directions and priorities. This comprehensive analysis provides a synergistic ground, which at this embryonic stage of development, can be used to set out joint trajectories and reciprocal foci across the whole span of scholarship studying planned series of events.

Full textAbstract:
The unique high-frigid environment and poor natural conditions of Qinghai–Tibet Plateau (QTP) have limited sustainable economic and social development. The construction of the beautiful QTP is a concrete implementation of the United Nations Sustainable Development Goals. However, identifying the progress and system coupling relationships of beautiful QTP construction entails some barriers due to data and methodological issues. To evaluate beautiful QTP construction and achieve a coordinated development regime, this paper employs an analytic hierarchy process and coupling model to quantify the comprehensive index and the coupling relationships of five subsystems (i.e., ecological environment, cultural inheritance, social harmony, industrial development, and institutional perfection) based on point of interest (POI) data, which are highly accurate, containing quantity and location information. Meanwhile, spatial autocorrelation analysis is conducted on the comprehensive index and coupling coordination degree for identifying the spatial clustering characteristics of the two. Results show that the progress of the beautiful QTP construction in most counties are under a very low or low level. For the system coupling perspective, 86% of counties are under the coupling stage indicating a strong interaction among the subsystems. However, coordination is out of harmony in most counties. For the spatial clustering characteristics, the comprehensive index and the system coupling relationships of beautiful QTP construction show a positive spatial correlation, indicating an aggregation effect. The aggregation is mostly “low–low” and “high–high” aggregation indicating the spatial differences and regional imbalances. The government should adopt measures to make the five subsystems of beautiful QTP construction more synergistic to achieve the sustainable development of the QTP. Our study formed a sample case of special areas where statistical data are scarce while constructing a technical framework of Beautiful China construction that is applicable to these areas. The findings of this study can serve as a reference for improving the beautiful QTP or other similar areas of construction.

"Exploring Industry 4.0 technologies to enable circular economy practices in a manufacturing context." Journal of Manufacturing Technology Management 30, no. 3 (April 15, 2019): 607–27. http://dx.doi.org/10.1108/jmtm-03-2018-0071.
Full textAbstract:
Purpose The purpose of this paper is to explore how rising technologies from Industry 4.0 can be integrated with circular economy (CE) practices to establish a business model that reuses and recycles wasted material such as scrap metal or e-waste. Design/methodology/approach The qualitative research method was deployed in three stages. Stage 1 was a literature review of concepts, successful factors and barriers related to the transition towards a CE along with sustainable supply chain management, smart production systems and additive manufacturing (AM). Stage 2 comprised a conceptual framework to integrate and evaluate the synergistic potential among these concepts. Finally, stage 3 validated the proposed model by collecting rich qualitative data based on semi-structured interviews with managers, researchers and professors of operations management to gather insightful and relevant information. Findings The outcome of the study is the recommendation of a circular model to reuse scrap electronic devices, integrating web technologies, reverse logistics and AM to support CE practices. Results suggest a positive influence from improving business sustainability by reinserting waste into the supply chain to manufacture products on demand. Research limitations/implications The impact of reusing wasted materials to manufacture new products is relevant to minimising resource consumption and negative environmental impacts. Furthermore, it avoids hazardous materials ending up in landfills or in the oceans, seriously threatening life in ecosystems. In addition, reuse of wasted material enables the development of local business networks that generate jobs and improve economic performance. Practical implications First, the impact of reusing materials to manufacture new products minimises resource consumption and negative environmental impacts. The circular model also encourages keeping hazardous materials that seriously threaten life in ecosystems out of landfills and oceans. For this study, it was found that most urban waste is plastic and cast iron, leaving room for improvement in increasing recycling of scrap metal and similar materials. Second, the circular business model promotes a culture of reusing and recycling and motivates the development of collection and processing techniques for urban waste through the use of three-dimensional (3D) printing technologies and Industry 4.0. In this way, the involved stakeholders are focused on the technical parts of recycling and can be better dedicated to research, development and innovation because many of the processes will be automated. Social implications The purpose of this study was to explore how Industry 4.0 technologies are integrated with CE practices. This allows for the proposal of a circular business model for recycling waste and delivering new products, significantly reducing resource consumption and optimising natural resources. In a first stage, the circular business model can be used to recycle electronic scrap, with the proposed integration of web technologies, reverse logistics and AM as a technological platform to support the model. These have several environmental, sociotechnical and economic implications for society. Originality/value The sociotechnical aspects are directly impacted by the circular smart production system (CSPS) management model, since it creates a new culture of reuse and recycling techniques for urban waste using 3D printing technologies, as well as Industry 4.0 concepts to increase production on demand and automate manufacturing processes. The tendency of the CSPS model is to contribute to deployment CE in the manufacture of new products or parts with AM approaches, generating a new path of supply and demand for society.

Abstract Inspired by the interesting natural antimicrobial properties of honey, biohybrid composite materials containing a low-fouling polymer hydrogel network and an encapsulated antimicrobial peroxide-producing enzyme have been developed. These synergistically combine both passive and active mechanisms for reducing microbial bacterial colonization. The mechanical properties of these materials were assessed using compressive mechanical analysis, which revealed these hydrogels possessed tunable mechanical properties with Young’s moduli ranging from 5 to 500 kPa. The long-term enzymatic activities of these materials were also assessed over a 1-month period using colorimetric assays. Finally, the passive low-fouling properties and active antimicrobial activity against a leading opportunistic pathogen, Staphylococcus epidermidis, were confirmed using bacterial cell counting and bacterial adhesion assays. This study resulted in non-adhesive substrate-permeable antimicrobial materials, which could reduce the viability of planktonic bacteria by greater than 7 logs. It is envisaged these new biohybrid materials will be important for reducing bacterial adherence in a range of industrial applications.

Full textAbstract:
The study of the practice of inter-organizational network interaction of enterprises has shown that one of the main reasons for the emergence is the need to set up adequate to the modern needs of the system of consumer value. Therefore, the network approach to the study of quasi-integration relations become popular in economics and management increasingly. The purpose of the article was to evaluate the synergetic effect of network interaction of enterprises using improving methodological tools for quantitative assessment of the effectiveness of quasi-integration. According to the results of the research, the methodical toolkit of quantitative estimation of the synergetic effect of network interaction of the enterprises has been improved on the basis of the system of indicators and a technique of calculation of an integrated indicator of synergy. When assessing the synergetic effect, the emphasis has been on the indicators of competitiveness of enterprises, which according to the results of the using method of a graph, which shows the relationship of indicators to assess the effectiveness of network interaction, was the resultant and reflected the impact to other indicators. The advantages of advanced methodological tools are the objectivity of evaluation, quantitative expression of the effect through the growth of individual performance indicators, integrated assessment of their overall change, and suitability for use in domestic business conditions. The synergetic effect for the enterprises of the mechanical engineering in the Kharkiv region has been estimated for the period of 2015-2019, using the improved method what have testified to the highest efficiency of network interaction management within the industrial group «Ukrainian Industrial Energy Company». The lowest synergetic effect was demonstrated by the enterprises that are part of the State Concern Ukroboronprom. For most of these companies, the synergistic effect has been determined as negative or non-existence. The value of the obtained results in this research lies in the methodological level - as a tool to assess the synergetic effect, and practical - as a basis for the development of tactical and strategic measures for improving the management of business networks in mechanical engineering.
