Along with the developing of flexible electronics, there is a strong interest in high performance flexible energy storage materials. As natural carbohydrate polymer, cellulose fibers have potential applications in the area due to their biodegradability and flexibility. However, their conductive and electrochemical properties are impossible to meet the demands of practical applications. In this study, cellulose fibers were combined with polyaniline to develop novel paper-based supercapacitor electrode material. Cellulose fibers were firstly coordinated to Cu(II) and subsequently involved in polymerization of polyaniline. Not only the mass loading of polyaniline was significantly increased, but also an impressive area specific capacitance (2767 mF/cm2 at 1 mA/cm2) was achieved. The developed strategy is efficient, environmentally friendly, and has implications for the development of cellulosic paper-based advanced functional materials.

This paper asks whether, and if so how, it is possible to design a system characterised by coordination across sectors and levels of governance aimed at governing AMR. The ambition is, firstly, to analyse how coordination problems materialise in the governing of the AMR problem, and secondly, with an emphasis on the structure of decision-making and communication processes, to probe into how coordination of AMR governance is achieved. The paper’s focus is on Norway, which stands out as one of the better performing countries for AMR governance. Drawing on literature on coordination and governance, the paper argues that effective coordination of AMR governance is more likely to follow a ‘bottom-up’ sequencing pattern. It thus provides a study of the systems for governing AMR in a multi-level setting. Through public documents, literature and interviews with key officials involved in AMR management, the paper illustrates the importance of – and organisational barriers to – inter-sectoral cooperation and coordinated strategies and actions at different levels of governance.

With the rapid expansion of the flexible electronics market, it is critical to develop high-performance flexible energy storage electrode materials. Cellulose fibers, which are sustainable, low cost, and flexible, fully meet the requirements of flexible electrode materials, but they are electrically insulating and cause a decrease in energy density. In this study, high-performance paper-based flexible electrode materials (PANI:SSA/Zr-CFs) were prepared with cellulose fibers and polyaniline. A high mass loading of polyaniline was wrapped on zirconia hydroxide-modified cellulose fibers under metal-organic acid coordination through a facile in situ chemical polymerization process. The increase in mass loading of PANI on cellulose fibers not only improves the electrical conductivity but also enhances the area-specific capacitance of the flexible electrodes. The results of electrochemical tests show that the area specific capacitance of the PANI:SSA/Zr-CFs electrode is 4181 mF/cm2 at 1 mA/cm2, which is more than two times higher than that of the electrode with PANI on pristine CFs. This work provides a new strategy for the design and manufacture of high-performance flexible electronic electrodes based on cellulose fibers. [ABSTRACT FROM AUTHOR]

Background: The aim of the study was to investigate the effectiveness of telerehabilitation-based balance and coordination exercises on balance confidence, fall efficacy, and functional independence in stroke patients. Methods: A double-blind, randomized controlled trial was conducted on 30 stroke patients (15 in the telerehabilitation-based group and 15 in the paper-based control group). The telerehabilitation group received video-based exercise training, while the control group received paper-based exercise training. Fear of falling (FES-I), balance (ABC), self-management (SSEQ) and satisfaction with telemedicine (TSQ) were evaluated before and six weeks after treatment. Results: The results of the present study showed that both telerehabilitation-based video training and paperbased exercise prescription methods were effective in terms of balance confidence, fall efficiency and stroke-specific functional independence (p<0.05). Besides, telerehabilitation-based video training was more effective in balance confidence (p=0.042) and functional independence (0.018). In addition, the satisfaction of individuals in the telerehabilitation group with the telerehabilitation application was above average (59.73±8.15). Conclusion: Telerehabilitation-based video exercises in stroke patients may provide additional advantages in terms of balance confidence and fall efficiency. In addition, individuals with stroke were satisfied with the remote rehabilitation application. [ABSTRACT FROM AUTHOR]

A research gap exists in the understanding of multi-level governance for watersheds in Kenya under the current devolved framework. This paper uses the Migori River watershed as a case study to elaborate on the institutional arrangement in the management of the watershed and how it influences the nature and level of coordination among the actors involved. The data was collected through semi-structured interviews and content analysis of secondary data. The target institutions were selected based on existing policy and legal frameworks, press releases, and published administrative reports. Respondents for the semi-structured interviews were identified through purposive and snowball sampling techniques. The qualitative data was then analysed through content analysis. After analysis of the nature of coordination, a panel of experts rated each coordination dimension based on a comparison between the findings and the baseline indicators. The results on the structure and roles of institutions revealed adequate representation of the river basin management actors, but the associations among actors are weak due to overlapping mandates and gaps in the administration processes of river basin management programs. Coordination exists, but it is not all-encompassing; whereas efforts to collaborate were noted, they were inconsistent and tended to be on a per-need basis due to a lack of a common forum for stakeholder interactions and a common management plan for a clear vision and direction of actors' activities. There is an unclear delineation of roles in the institutional structure and thus causing institutional complexity, which further undermines coordination. To address the coordination gaps, the paper recommends the creation of a management council for the watershed to provide a central forum for the stakeholders' interaction, with a designated lead agency that organizes and facilitates meetings, oversees communications, and manages any emerging challenges, gaps and opportunities in collective actions.

The transformer grounding is typically inserted across a transformer or generator's ground. In a transformer and generator, this ground is often used to reduce the current of a disturbance from phase to earth. During a ground fault in a transformer, a very high current can flow, posing a danger to equipment and personnel. By connecting a resistor between the neutral point of the transformer and ground, the NGR limits this fault current. In the following paper, the protection mechanism of two high-voltage to medium-voltage transformers which connected in parallel during routine operation as well as in emergency situations will be explored. Protecting two parallel transformers with two different neutral grounding resistors involves ensuring proper coordination of protective devices to detect and isolate faults while minimizing damage to equipment and ensuring system stability. Another scenario under discussion involves a generator linked to the medium-voltage (MV) system, which distinct had a distinct ground value. A short circuit occurring in different neutral grounding resistor (NGR) systems refers to a fault scenario where more than one transformer or generator linked in parallelly, each with its own NGR of varying resistance values. This situation poses challenges for protection coordination and fault current distribution. To address this issue, a protective scheme is suggested, which modifies its configurations according to the operational status of the system. [ABSTRACT FROM AUTHOR]

This article explores the balance, and the shift in balance, between technologies and practices that coordinate work. The empirical data stems from a primarily qualitative study of a Norwegian shipyard in a phase of transition, where new models of collaboration emerge due to changes in the company environment. The article highlights the interplay between formal and informal articulation work, as well as the role of coordinative IT artifacts in this regard. With this background, the findings show that the balance (between coordinative technologies and practices) shifts depending on circumstances. Thus, the more formal coordination gains importance as transitions increases the need for detailed instructions. The findings also show that the existing IT infrastructure (the legacy) lacks the granularity as a coordinative artifact to facilitate necessary change in the organizational work arrangement, and how the workers cope with such issues. Based on this, the paper provides insights into how articulation work and its sociomaterial aspects develops over time in the interplay of organizational and technological change (or lack thereof).

AbstractThis paper deals with practices of personal mobility in public space, such as walking, passing-by and queuing, and their intelligible, recognizable and intersubjectively coordinated character. People co-exist in public places without having to explain their conduct in so-many-words; they smoothly navigate by coordinating their bodies and mobile trajectories without collisions; they queue without any instructions and differentiate between who joins the queue and who projects to butt in the queue. This article addresses the intelligibility of walking trajectories in public space, how they are bodily achieved and visibly interpreted. It reflects on mobility by relying on the notion of
public in two different but complementary perspectives: a) by reference to mobility in the context of public places such as parks, squares, and streets; b) by reference to the public intelligibility and recognizability of mobile actions in social interaction. The convergence between these two notions ofpublic enables us to investigate how mobile social actions are formed (maderecognizable ) and how they are ascribed (actuallyrecognized ) by co-present unacquainted persons in public space. The analysis draws on video recordings of mobile trajectories in streets, pathways, and squares. [ABSTRACT FROM AUTHOR]- Published

Increasing resilience to flooding is a complex process that requires horizontal and vertical coordination between institutions in policy making and implementation. This paper explores the effect of institutional coordination on managing flood risk in two cities plagued by flooding. Our results show that efforts on building urban flood resilience can be undermined by lack of proper coordination between urban development, water management and land use planning. We find that this complexity is magnified by the emergence of the concept of resilience as an urban development goal that is increasingly pursued by various authorities, but that is inherently contested in practice.

Assous, Michaël and Carret, Vincent
- Abstract
AbstractThis paper documents an early fork in the development of macroeconomics, by examining a debate between the Dutch economists Jan Tinbergen and Johan Koopmans. In a 1932 paper, Tinbergen argued that two firms could be stuck in a “bad” equilibrium in the absence of a coordinated action to incrase employment. Koopmans replied with a paper demonstrating that multiple equilibria in an exchange economy could not be ranked on the basis of their productive efficiency. This debate contributed to a larger turn away from dynamising the general equilibrium model, towards the new field of macrodynamics, with long-ranging consequences for the field.

This paper focuses on a two-stage coordination strategy for distributed storage systems located at the end-user level. A first day-ahead commitment stage lies on the Alternating Direction Method of Multipliers adapted to a decentralized problem in which the followers and leaders exchange prices (Lagrangian)/quantities information over iterations. Then a three-step coordination is proposed for real-time control to guarantee a fast convergence while trying to remain as close as possible to the profiles scheduled in the look-ahead stage. Specific attention is attached to the end-users' objective function and their willingness to respond to coordinator signals. A layout of up to 100 households is simulated with the performances assessed regarding the trade-off between loss of revenue and global objective improvements. The impacts of load and solar generation forecasts errors are also investigated along with the effect of storage parameters. Obtained results highlight the need for a trade-off between the targeted objective in the look-ahead phase, and the confidence that it can be fulfilled in real-time. [ABSTRACT FROM AUTHOR]

Strategies based on performance measurement and feedback are commonly used to support quality improvement among nurses. These strategies require practice change, which, for nurses, rely to a large extent on their capacity to coordinate with each other effectively. However, the levers for coordinated action are difficult to mobilize. This discussion paper offers a theoretical reflection on the challenges related to coordinating nurses' actions in the context of practice changes initiated by performance measurement and feedback strategies. We explore how Jürgen Habermas' theory of Communicative Action may shed light on the issues underlying nurses' collective actions and self‐determination in practice change and the implications for the design of strategies based on performance measurement and feedback. Based on this theory, we propose differences between communicative and functional coordination according to the nature of the actions and the purposes involved. The domains of action underlying these coordination processes, which Habermas referred to as the lifeworld and the system, are then used to draw a parallel with aspects of nursing practice. Further exploration of these concepts allows us to consider the tensions between the demands of the system and the self‐determination of nurses within their practice. [ABSTRACT FROM AUTHOR]

Living systems at any given moment enact a very constrained set of end‐directed and contextually appropriate actions that are self‐initiated from among innumerable possible alternatives. However, these constrained actions are not necessarily because the system has reduced its sensitivities to themselves and their surroundings. Quite the contrary, living systems are continually open to novel and unanticipated stimulations that require a physiology of coordination. To address these competing demands, this paper offers a novel heuristic model informed by neuroscience, systems theory, biology and sign study to explain how organisms situated in diverse, complex and ever‐changing environments might draw upon the sparse order made available by 'relevant noise'. This emergent order facilitates coordination, habituation and, ultimately, understanding of the world and its relevant affordances. Inspired by the burgeoning field of coordination dynamics and physiologist Denis Noble's concept of 'biological relativity', this model proposes a view of coordination on the neuronal level that is neither sequential nor stochastic, but instead implements a causal logic of phasic alignment, such that an organism's learned and inherited sets of diverse biological affinities and sympathies can be resolved into a continuous and complex range of patterns that will implement the kind of novel orientations and radical generativity required of such organisms to adaptively explore their environments and to learn from their experiences.

[Gd(HP‐DO3A)] (gadoteridol) as an active compound of ProHance® is a widely employed contrast agent in clinical MRI scans in the last 30 years. Recent concerns about the long‐term retention of gadolinium‐based contrast agents (GBCAs) led to a deeper investigation of the structural features underlying the integrity of the paramagnetic metal complex. Several human and nonclinical studies have noted marked differences among the macrocyclic GBCAs, with the least retention of Gd traces and most rapid elimination consistently being reported for [Gd(HP‐DO3A)]. It was deemed of interest to assess how minor structural/electronic changes associated to the ligand structure may affect basic properties of the metal complex with several [Gd(HP‐DO3A)] analogues synthesized and characterized in the last years. We recently reported that the closest homolog of [Gd(HP‐DO3A)], i. e.: [Gd(HB‐DO3A)], in which a (±)‐2‐hydroxy‐1‐propyl pendant arm is replaced by a (±)‐2‐hydroxy‐1‐butyl moiety, showed a significantly different retention behaviour in the model interaction with collagen, despite the apparently very minor structural difference. In this paper we report a comprehensive study of the structural, thermodynamic, kinetic and relaxation properties of [Gd(HB‐DO3A)], compared to the parent [Gd(HP‐DO3A)] and to other closely related macrocyclic GBCAs to assess whether very minor structural changes can modulate the physico‐chemical properties of Gd3+ complexes.

In this paper is present the procedure for introducing the coordination of light signals at five intersections on the Boulevard "St. Kliment Ohridski" in Skopje. The primary purpose of a traffic signal is to assign the right-of-way to intersecting traffic streams for the purpose of ensuring that all streams are served safely and without excessive delay. A properly designed and timed signalized intersection will minimize fuel consumption, delay, and stops without having an adverse effect on safety. Travelers will realize one or more of the following benefits at intersections where the traffic signal is needed, properly designed, and well timed: orderly movement of traffic, increase in the traffic-carrying capacity of the intersection, reduction in the frequency and severity of certain types of crashes, progressed traffic when traveling in a coordinated signal system, and interruption of heavy traffic flow to provide safe opportunities for minor movements. Coordinated signal timing synchronizes traffic movements and manages the progression speed of specific modes where uninterrupted flow is desired along a corridor. While traditionally applied to increase vehicular traffic flow and reduce peak-hour delay, coordinated signal timing can also be optimized for slower speeds, creating an uninterrupted flow for bicyclists or low vehicle progression speeds for a pedestrian-friendly downtown. Signals may also be timed to coordinate transit headways along routes where regular transit service is consistent and has low variability. Coordination of traffic signals can reduce the number of stops along a corridor and provide for a continuous flow of traffic at the target speed. Progression speeds should be set at or below the target speed, rather than existing 85th percentile speeds. [ABSTRACT FROM AUTHOR]

17. Imperfect coordination in DSGE models: The resurgence of Keynes in mainstream macroeconomics.

Clerc, Pierrick and Dos Santos Ferreira, Rodolphe
- Abstract
AbstractThe imperfect coordination of expectations and actions is a central theme running through Keynes’s
General Theory . Incorporating this theme into mainstream macroeconomics, however, has proved to be a difficult endeavour. In particular, attempts to accommodate coordination failures within Dynamic Stochastic General Equilibrium (DSGE) models through multiple equilibria and “dynamic” indeterminacy, while promising in the 1990s, were gradually abandoned in the 2000s. Since then, the “New Keynesian” framework has come to dominate macroeconomic modelling. And since the coordination of agents is not at issue in this latter framework, mainstream macroeconomics has seemed to leave the coordination theme out of its focus, if not its scope. In this paper, we challenge this perception and argue that the coordination theme is actually alive and well. We especially present two recent research programmes which, while belonging to the DSGE paradigm, give pride of place to coordination failures and share a common objective: providing, within the class of DSGE models, an alternative to the New Keynesian framework that would involve the most important ideas emerging from Keynes’sGeneral Theory .

• Country ownership is one of the four guiding principles for the Immunization Agenda 2030. • There is little practical guidance on what country ownership is and how to operationalize it. • Measles and rubella programs are used to illustrate country ownership in operation. • Five elements of country ownership - commitment, coordination, capacity, community participation, and accountability - are described. • Our work is a useful guide for immunization program strategy development. Country-owned, as opposed to donor-driven, is a principle within the development sector that recognizes the centrality of countries' leadership, systems, and resources in executing programs and achieving sustainable development. In alignment with this notion, the Immunization Agenda 2030 was developed with country ownership as one of four core principles of the ambitious ten-year plan. This means that the success of immunization programs, including those with eradication and elimination goals such as polio, measles, and rubella, and those with broader equity goals to "leave no one behind" on immunization, would be largely driven by country systems. In this paper we deconstruct country ownership into five operational principles: commitment, coordination, capacity, community participation, and accountability. Through this lens, we illustrate how two countries, Nepal and Nigeria, have exemplified country ownership in their measles and rubella elimination programs and we infer the ways in which country ownership drives system performance and sustains program efforts.

AbstractThis paper elaborates on four different reasons why the assumption of continual dynamic stochastic general equilibrium, which is now standard in mainstream macroeconomics but is not used in agent based macro, makes a macro model less useful: (1) it assumes away most coordination problems, (2) it hides possible instabilities, (3) it makes money look unimportant, and (4) it makes inflation look trivial.

Grassé[26] coined the term stigmergy (previous work directs and triggers new building actions) to describe a mechanism of decentralized pathway of information flow in social insects. In general, all kinds of multi-agent groups require coordination for their effort and it seems that stigmergy is a very powerful means to coordinate activity over great spans of time and space in a wide variety of systems. In a situation in which many individuals contribute to a collective effort, such as building a nest, stimuli provided by the emerging structure itself can provide a rich source of information for the working insects. The current article provides a detailed review of this stigmergic paradigm in the building behavior of paper wasps to show how stigmergy influenced the understanding of mechanisms and evolution of a particular biological system. The most important feature to understand is how local stimuli are organized in space and time to ensure the emergence of a coherent adaptive structure and to explain how workers could act independently yet respond to stimuli provided through the common medium of the environment of the colony.

The paper revises etymologies of Croatian adversative conjunction ali, commonly associated with Polish ale. Even though both lexemes contain a conjunction a, they are composed of a question particle li and restrictive particle le respectively. Old Croatian, Serbian, and modern Slovenian disjunctive function of ali seems to be unrelated to the adversative function, which might have evolved directly from rhetorical questions. The paper shows what such change could look like, in line with the pragmatics of rhetorical questions and adversative coordination, Old Church Slavonic examples, and the uses in Old Croatian texts.

Interval demand is becoming more common than ever before, since the variation bounds of uncertain demand are only required in practice, and they could be obtained through only a small amount of uncertain information. The goal of this paper is to analyze the optimal decision and coordination of a competitive dual-channel supply chain under an interval uncertain demand. For this purpose, we establish a centralized decision model and a wholesale price contract model under both interval demand and channel competition, respectively. Meanwhile, both the satisfaction degree of interval and the order relation of interval number are proposed to convert interval uncertain optimization problems to deterministic ones. Then, we derive the optimal pricing decisions, ordering quantities, and performances of partners and the supply chain system. Meanwhile, a revenue sharing contract is proposed to coordinate the competitive dual-channel supply chain under interval demand. Moreover, we found that the bounds of interval demand and channel sensitivities affect the optimal strategies and revenue sharing contract under interval uncertainty. Finally, we present a numerical analysis to illustrate the proposed results in this paper and conduct sensitivity analyses. The findings of this paper provide important references for decision makers and managers to make scientific decisions in an interval uncertain environment. [ABSTRACT FROM AUTHOR]

With the penetration of distributed resources into power distribution networks, power distribution networks are transforming into active distribution networks with a high proportion of distributed generations and power electronic equipment. Efficient modeling and simulation methods are essential to perform dynamic response analysis. In order to satisfy the fast/steady/slow multiple time-scale simulation requirements of active distribution networks, a fast/medium/slow time partition model and a network decoupling method for short line characteristic lines is proposed in this paper. Through the decomposition coordination simulation method, the network is decomposed into multiple regions that can be simulated in parallel. Based on the interconnection of fiber optic network cards, a multi-rate parallel simulation and synchronization strategy is proposed, which significantly improves the simulation speed of active distribution networks while ensuring simulation accuracy. The numerical experiments have been conducted based on a modified IEEE 33-bus and a PG&E 69-bus, and simulation results show the feasibility of the proposed method. The verification results of the example show that using adaptive variable-step-size multi-rate parallel simulation technology can increase the subnet computation-time balance rate and simulation acceleration ratio to 119.90% and 121.31% in the same rate-parallel mode.

This paper focuses on the actions and partnerships established between members of the State Secretariats of Health and Social Assistance in Rio de Janeiro and other organizations in the health and assistance areas to respond to the health emergency triggered by the congenital Zika virus syndrome between 2015 and 2018. Some characteristics of the context were: a severe economic crisis, the erosion of the governance capacities of the state political authorities as well and scarce technicalscientific knowledge about the epidemic. The study was grounded on an analysis of documents related to the topic, 17 semi-structured interviews with managers and professionals from the two secretariats. Interview scripts focused on intersectoral actions and processes of cooperation and coordination within and between organizations.

Today, supply chain finance is a very important topic. Traditional supply chains rely on banks to support the related financing activities and services. With the emergence of blockchain technology, more and more companies in different industries have considered using it to support supply chain finance. In this paper, we study supply chain financing problems in supply chains selling fashionable products. Modeling under the standard newsvendor problem setting with a single manufacturer and a single retailer employing a revenue sharing contract, we develop analytical models for both the traditional and blockchain-supported supply chains. We derive the optimal contracting and quantity decisions in each supply chain with Nash bargaining between the manufacturer and retailer. We analytically show how the revenue sharing contract can coordinate both types of supply chains. We then compare the optimal systems performances between the two supply chains. We prove that the blockchain-supported supply chain incurs a lower level of operational risk than the traditional supply chain. We have shown that if the service fees by banks are sufficiently high, adopting blockchain technology is a mean-risk dominating policy which brings a higher expected profit and a lower risk for the supply chain and its members. For robustness checking, we examine other commonly seen supply chain contracts and alternative risk measures, and analytically reveal that the results remain valid. [ABSTRACT FROM AUTHOR]

In this paper, we study cooperation and coordination in a threshold public goods game with asymmetric players where players have different endowments e i , productivities p i , and rewards r i . In general, this game has a defective Nash equilibrium (NE), in which no one contributes, and multiple cooperative NEs, in which the group's collective contribution equals the threshold. We then study how multiple dimensions of inequality influence people's cooperation and coordination. We show that heterogeneity in e i p i can promote cooperation in the sense that the existence condition of the defective NE becomes stricter. Furthermore, players with higher e i p i are likely to contribute more at a cooperative NE in terms of collective contribution (i.e., absolute contribution multiplied by productivity).

The present paper explores the nexus of coordination and referential dependencies, focusing on sentences such as 'Max and Lucie talked about him', in which it is hardly possible for Max and him to be co-valued. Previous accounts claim that such referential dependencies are in fact possible on a collective reading. It will be demonstrated here, however, that informants consistently judge the co-valued reading in such cases to be either strongly marginal or unavailable, regardless of whether a collective or distributive reading obtains. It is claimed that the manner in which referential dependencies interact with coordinate structures can be addressed insightfully in terms of 'predicate-valent' structures (as opposed to 'predicate-argument structures'). A constraint in this regard will be proposed: the 'Conjunct Referential Dependency Constraint' (CRDC). The CRDC is couched in a Dependency Grammar (DG) approach to syntax. [ABSTRACT FROM AUTHOR]

The data revolution has resulted in discussions in the statistical community on the future of official statistics. Will official statistics survive as a brand, or will such statistics drown in the flow of data and statistics from new sources and actors, including misused statistics and fake news? The COVID-19 pandemic has been an additional driver for discussion. There is a need to maintain the quality of official statistics and highlight the value of such statistics for the users as a basis for – and supplement to – other statistics and information. It is at the same time important to implement new developments to improve and keep up the relevance of official statistics. Key pillars today are statistical legislation, quality frameworks and core values defining requirements for official statistics. Possibilities are linked to new statistics, use of new data sources and possible extended roles of the statistical institutes within coordination, collaboration, and data stewardship. The paper addresses these issues in the light of trends in official statistics since the UN Fundamental Principles of Official Statistics were formulated about 30 years ago. Quality challenges for statistics and dilemmas in defining the roles of statistical institutes are considered. The paper includes examples from Statistics Norway. [ABSTRACT FROM AUTHOR]

- Abstract
The development of scientific research in the Guangdong-Hong Kong-Macao Greater Bay Area is unbalanced and inadequate, and its contribution to technological innovation is insufficient to meet the huge demand for industrial innovation in the Greater Bay Area. This paper tries to clarify the coordination relationship between scientific research and industrial innovation in the Guangdong-Hong Kong-Macao Greater Bay Area since 1997 by constructing the scientific research-industrial innovation coordination data sets, correlation index and relative development index for ten industries in the area. This paper analyzes the evolution and interaction rules of scientific research and industrial innovation in the Guangdong-Hong Kong-Macao Greater Bay Area, and puts forward corresponding countermeasures. The research found that scientific research and industrial innovation in the Guangdong-Hong Kong-Macao Greater Bay Area showed an overall upward trend while the coordinating level varies from industry to industry. Among the ten industries analyzed in this paper, communication technology and integrated circuit have reached a high level of coordination; marine engineering equipment is still in the primary coordination stage; and other industries are at a good level of coordination. The scale advantage and competitive advantage of scientific research are dynamic for the improvement of coordination level, which suggests that we should combine the scale effect and competitive advantage of innovation, pay high attention to originality and leadership, and strive to form the special and preponderant advantage of regional scientific research.

One of the primary tasks of organisations is to find a way to use the knowledge they have at their disposal. From this perspective, organisations have three critical tasks; to manage their employees' personal knowledge, make personal knowledge of employees available for their colleagues, and find how to use the knowledge embedded in artefacts and procedures. Coordination and organising are managerial activities through which organisations orchestrate their employees' work and knowledge and balance reliability and adaptability. Coordination is a horizontal process of orchestration of individual activities and knowledge by rules, guidelines, normative or spontaneous emergent activities of individuals and organising is a vertical process through which organisations make their decisions. This paper aims to discuss how different arrangements of coordination and organising influence work with knowledge. The paper explains the potential, advantages and disadvantages of different arrangements of coordination and organising for work with knowledge and provides examples of organisations that use these arrangements in practice.

This paper investigates a green supply chain (GSC) consisting of one manufacturer and one retailer who possesses private demand forecast information. To promote green consumption, the government may provide subsidies to consumers. Within a dynamic game where the manufacturer serves as the leader and the retailer acts as the follower, three cases are examined: centralized decision, decentralized decision with and without demand forecast information sharing between the retailer and the manufacturer. We mainly examine the value of information sharing on the decisions of a GSC in the context of government subsidies for consumers. We find that: (i) demand forecast information sharing benefits the manufacturer but damages the retailer; (ii) if the predicted value is higher than the determinate part of the demand, the manufacturer is willing to choose a higher green degree of products in the case with information sharing compared with that without information sharing; otherwise, the manufacturer is willing to choose a lower green degree of products; (iii) a two-part tariff contract is appropriate to coordinate the GSC and it is effective in increasing the green degree of products; (iv) information sharing benefits the GSC if the green production efficiency is high enough; (v) the ex-ante social welfare always increases with information accuracy. Finally, numerical analyses are conducted to verify the above findings. [ABSTRACT FROM AUTHOR]

RANDOM variables - Abstract
In the first part of this paper we develop some theorems in linear algebra applicable to information theory when all random variables involved are linear functions of the individual bits of a source of independent bits. We say that a collection of subspaces of a vector space are coordinated if the vector space has a basis such that each subspace is spanned by its intersection with the basis. We measure the failure of a collection of subspaces to be coordinated by an invariant that we call the discoordination of the family. We develop some foundational results regarding discoordination. In particular, these results give a number of new formulas involving three subspaces of a vector space. We then apply a number of our results, along with a method of Tian to obtain some new lower bounds in a special case of the basic coded caching problem. In terms of the usual notation for these problems, we show that for N = 3 documents and K = 3 caches, we have 6 M + 5 R ≥ 11 for a scheme that achieves the memory-rate pair (M , R) , assuming the scheme is linear.

- Abstract
Abstract \nPoints of interest This paper uses a neo-institutional perspective to examine possibilities and obstacles for participation in coordinated individual planning (CIP) for people with intellectual disabilities. CIP is a tool for interprofessional and interorganizational coordination with the objective of creating a joint plan for a person needing cohesive care. Participation by the service-user is considered important for effective coordination but involving someone with an intellectual disability may require special adaptations. A thematic analysis of interviews with 17 professionals from different organizations in Sweden reveals that service user participation is considered an important goal by professionals, but also that it is difficult to put into practice. The results indicate that CIP is characterized by tensions and policy-practice decoupling that limit the service-users’ possibilities for participation. Different organisations and professionals sometimes give support to one individual. They need to coordinate this support. It is necessary for service-users to be involved in coordinated planning of the support and care they need. The study analyses how professionals experience participation in coordinated planning when the service-user has an intellectual disability. The study found that coordinated planning can be difficult to adapt for service-user participation. The study found a gap between ideals and practice caused by the organizations’ rules, norms, and structures. The findings reveal a risk of focusing on changing the service-user’s behaviour or situation rather than addressing problems within the organizations.

Cultural Heritage Projects (CHP) are complex activities that involve multiple and heterogeneous actors attempting to harmonize their different and diverse ontological and epistemological perspectives, while simultaneously coordinating and sharing knowledge about heritage objects. Projects involve a multitude of related data, information, and knowledge, and require information technologies for coordination. In this context, the socio-technical approach to designing information systems (IS) has become widely adopted but it is contradictory in knowledge coordination scenarios in which heritage experts and coordination technologies form inseparable sociomaterial assemblages that evolve through routines and affordances, depending on the contextual dimensions of particular projects. This paper adopts a design science approach to present the sociomaterial design of a Knowledge Management System (KMS) for cultural heritage projects. The KMS aims to overcome coordination issues for sharing knowledge within and between heritage projects. Evaluation results outline that the KMS provides enhanced knowledge access and visualization, greater flexibility in sharing practices, and improved decision-making capabilities. The designed system meets the specific requirements of an international knowledge sharing network and introduces innovative design and coordination insights that can be successfully deployed in heritage projects and networks with similar coordination and collaborative features.

As Richard Day pointed out, an evolutionary approach focuses on the characterization of the way economies function when they work out of equilibrium and represents their capacity to change structure. Our paper aims at providing the basis of the analysis of qualitative change as learning process whose evolution is not predetermined but depends on what happens along the way, that is, on the recurrent distortions in the time structure of productive capacity due to co-ordination failures. Qualitative change is a change that implies a structural modification, which can only be brought about through a process in real, irreversible time. Physical, human, and financial capital are complementary in this process of reshaping and may constrain each other. Viability of the disequilibrium process depends then on the interaction between behaviors and policies. [ABSTRACT FROM AUTHOR]

Most European Administrative Networks (EANs) have been operational for over two decades. Yet, our understanding of their evolution is limited. How do EANs evolve? I formulate two hypotheses, premised on the notion that networks help actors address collective action problems by establishing social capital, whose distribution in the network changes over time to respond to changed circumstances. Using a Bayesian network model of the structure of the Council of European Energy Regulators (CEER) at two-time points (1998 and 2014), this paper shows that regulatory relationships shifted from being focused on learning to be aimed at achieving compromise in order to influence European policy-making. Rather than functional, static devices of rule harmonization, EANs are dynamic social networks that adapt to their changing environment. The paper provides a theoretical background and empirical approach to understand and analyse EANs evolution in different sectors. [ABSTRACT FROM AUTHOR]

In times of crisis, governments have strong incentives to influence banks' credit allocation because the survival of the economy depends on it. How do governments make banks 'play along'? This paper focuses on the state-guaranteed credit programs (SGCPs) that have been implemented to help firms survive the COVID-19 crisis. Governments' capacity to save the economy depends on banks' capacity to grant credit to struggling firms (which they would not be naturally inclined to do in the context of a global pandemic). All governments thus face the same challenge: How do they make sure that state-guaranteed loans reach their desired target and on what terms? Based on a comparative analysis of the elaboration and implementation of SGCPs in France and Germany, this paper shows that historically-rooted institutionalized modes of coordination between state and bank actors have largely shaped the terms of the SGCPs in these two countries.

Purpose: The purpose is to expand our understanding of different organizational group interactions in crises and extend the Competing Values Framework of organizational culture into three first responder groups – firefighters, police and emergency medical technicians. Because unique organizational culture is a critical element in the success or failure of any organization, when organizations combine during crisis, failure often results. The authors examined the cultures of first responders in a crisis to determine whether differences in cultural type might explain some failures. Design/methodology/approach: Using the Competing Values Framework for organizational culture, the authors examined literature on the three first responder cultures. The literature is available on the failure of these organizations to work together in crisis, but little on the deep organizational reasons for these failures. Findings: In view of the different challenges each profession faces and ways they organize to address those challenges, self-directed coordination of these three distinct groups may be optimal, rather than an overall system of command and control. This can be visualized when the authors examine the three cultures using the Competing Values Framework. The authors discuss specific reasons for problems in crisis coordination and give suggestions on coping with three or more different cultures. Research limitations/implications: This is a literature review and conceptual paper. A meta-analysis of incidences would be helpful. Practical implications: When disparate organizations work together, culture may interfere with cooperation and coordination. Taking organizational culture into account will enable operations with less friction. In this paper, the authors explain why. Social implications: Lack of cooperation and coordination among firefighters, police and EMTs could create loss of life or property. Understanding potential cultural differences will help the disparate groups work together better. Originality/value: The authors examine organizational culture differences in detail as a reason for the failures of coordination of first responders in crisis. In addition, the authors extend the Competing Values Framework to these essential groups of first responders. The authors are the first to propose a taxonomy of culture for these three groups, based on the Competing Values Framework. [ABSTRACT FROM AUTHOR]

This paper aims to analyze the impacts of a backup agreement contract on the performance of a small agricultural producers' citrus supply chain. A backup agreement contract, which ensures for each echelon that a quantity of products will be bought independently of real demand, is proposed to coordinate a three-echelon supply chain, aimed at improving income. After presenting an overview of the literature that shows various coordination mechanisms but no backup agreement proposals for supply chain coordination, this paper develops a decentralized three-echelon supply chain facing stochastic customer demand and includes the backup agreement as a coordination mechanism to guarantee a balanced relationship between the chain members. The model is tested in a real case study in Colombia, and a sensitivity analysis is provided. Results show that a backup agreement contract coordinates the small agricultural producers' supply chain and improves income for each echelon, especially for the small producer. However, the economic mechanism complexity can limit coordination among echelons, mainly because of a lack of trust and consolidated supply capacity from small farmers. The foregoing requires the development of an associative structure by small producers, which is proposed as future research work. [ABSTRACT FROM AUTHOR]

The fast development of urban built-up areas in China is causing many problems, such as pollution, congestion, etc. How to effectively evaluate the coordination between urban areas and environmental problems has been attracting many scholars worldwide. This paper intends to discover this "secretary" through investigating the built-up areas and their accompanied economic and environmental factors over almost 30 years (1992 to 2020) in Nanjing, China. DMSP/OLS nighttime lights images from 1992 to 2013 and the NPP/VIIRS nighttime lights images from 2012 to 2022 are used for extraction of built-up areas. A spatiotemporal evolution model is established to evaluate whether the built-up areas have developed in coordination and the relationship between urban built-up areas and various factors, including compactness, the fractal dimension, boundary and shape changes, exhaust emissions, and the production of general industrial solid waste, which was further investigated to ascertain whether there was coordination or not. The investigated results discovered that Nanjing's built-up areas had maintained continuous growth from 1992 to 2020, with the compactness of built-up areas gradually decreasing from 0.42 to 0.23 and the built-up differentiation dimension changing from 1.31 to 1.39, demonstrating that built-up areas had gradually moved from a loose pattern to a compact pattern and from irregular development to balanced development in all directions. The macro model of the coordination index change trend is 0.847 from 1995 to 2020, which indicates that the coordination between urban built-up areas of development and their environments has been improving; however, the reduction in urban green space, the increase in waste emissions, and the increased production of general industrial solid waste has raised questions regarding sustainable development.

With this paper we want to contribute to the debate on the usage of vocational training as a tool to promote the integration of disadvantaged groups. We focus in particular on programmes that target refugees and highlight the organisational and coordination challenges that must be addressed in order to develop such programmes. Relying on knowledge developed by scholars of collective skill formation and by those who have studied policy coordination, we develop a number of hypotheses that can account for the successful implementation of this type of programmes. We then test our hypotheses against an example taken from Switzerland, consisting of a one-year pre-apprenticeship dual training programme adopted in 2018. We argue that its win-win quality, the flexibility with which it was managed and possibly also the political salience of the issue of refugee integration at the time, were the key factors explaining its successful adoption.

This paper examines the crisis management learning by the Norwegian government after the COVID-19 pandemic by focusing on types of learning based on the concepts of governance capacity and legitimacy. Using unique interview data with 36 elite administrative and political executives in Norway, the study finds varied learning by the involved actors, and most learning about coordination between ministries and agencies, which are amplified by the lack of knowledge related to analytical capacity. The study contributes to advance the analytical understanding of crisis management learning and provides insight into what a high performing government in the pandemic attempts to learn.

Van Duijn and colleagues propose that minimal cognition can be understood in terms of sensorimotor coordination – that is the coordination between sensory apparatus of an organism and the motor processes that move it around the environment (2006). Despite there being much to recommend this account it still faces some challenges. For example, it does not accord with the intuition that there are cognitive processes that have little to do with sensorimotor coupling, it relies on a strong distinction between metabolic and cognitive processes, and perhaps counterintuitively it denies cognition to plants but grants it to the bacteria on their roots that perform various functions for them. Moreover, it is difficult to see how to account for cognition over the transition from single to multicellular organisms. This paper proposes taking a more radical view of cognition to be what happens in swarms – the coordination of multiple processes through the traces of their actions in the environment. Key to this approach is the observation that the structure of the environment plays an active coordinative role and that this structure results in part from the actions of the system that it helps coordinate. Systems develop sensitivity to the appropriate trace variables in the environment. Viewed as collections of processes bacteria, biofilms, plants, animals can be viewed as cognitive systems in this framework and it has the potential to be applied to the social world.

Time plays an integral role in understanding how the social is possible. However, most discussions of sociological classical thinkers—such as Georg Simmel—remain starkly underexplored in terms of their theories' temporal presuppositions. While most responses to Simmel's work credit him for his major contributions to the sociology of space, in this paper I aim to systematically reconstruct his explicit and implicit temporal assumptions and explore how these inform some of his social-theoretical writings and his sharp temporal diagnosis of modernity. For this purpose, I re-evaluate some of his central works using a theory distinction between social-theory, which aims to answer what constitutes the social, versus theory-of-society, where the key focus is what form or forms human societies have taken so far, and especially what form modern society takes. By offering a new reading of Simmel's philosophical and sociological writings, I formulate a comprehensive social theory of time, in which time is both located within individual consciousness and reciprocally mediated by a culturally fixed and supra-individual timeframe, thus highlighting the temporal tensions between individual flexibility and social standardization and coordination. Simmel's diagnosis of modernity reveals a conceptualization of time in spatialized terms, a monetization of time, and an acceleration of life. [ABSTRACT FROM AUTHOR]

This paper studies the impact of bilateral participation strategy on the dynamic emission-reducing behaviors and associated performance of low-carbon supply chains using differential game models. We first consider a dyadic supply chain comprising one supplier and one manufacturer in the base model and derive the equilibrium solutions of dynamic emission abatement in decentralized and centralized systems, respectively. In the decentralized supply chain, we consider both unilateral sharing and bilateral participation contracts and examine the feedback equilibrium strategies and trajectories of emission abatement of all parties. By comparison, we find that the bilateral contract leads to lower emission abatement and higher profits of all players and the system than that under unilateral sharing contract. Meanwhile, we show that the properly-designed bilateral participation contract can coordinate the decentralized dyadic supply chain. By extending the base model, we further figure out the equilibria and optimal trajectories for the dynamic cooperative emission abatement and the associated mechanism design in a supply chain with two competing suppliers and one manufacturer. Interestingly, we find that the bilateral participation contract can also coordinate the competing channels with competitive or complementary components at the upstream level. We uncover that the bilateral participation contract is effective in coordinating supply chains with dynamic cooperative emission abatement since it can overcome the disadvantage of uneven distribution of emission-reducing capability endowments among chain members. Finally, we also conduct computational and sensitivity analyses to illustrate the previous results. These findings provide potential implications for firms' dynamic cooperation in emission abatement.

The paper examines distributed extraction coordinations, in which different elements move out of conjuncts of a single coordination, as in Which book and which magazine did Mary buy and Amy read respectively, from a crosslinguistic perspective. A number of properties of such coordinations are discussed, which includes showing that they are also subject to the ATB requirement, which will shed light on the nature of the ATB phenomenon itself. It is also shown that there is a rather strong restriction on distributed extractions which confines such extractions to one context and completely excludes one type of movement, in particular head-movement, from participating in them. The higher coordination is shown to be formed during the derivation and to be semantically expletive. Distributed extraction constructions are also shown to have consequences for the proper analysis of a number of phenomena, including subject-oriented anaphors, right node raising, toughconstructions, agreement, and clausal structure. Regarding subject-oriented anaphors, the paper teases apart different approaches to subject-oriented anaphors based on constructions where different elements fill SpecvP and SpecTP (the latter undergoes agreement with T and the former binds subjectoriented anaphors).

Background: Children with neurodisability (ND) represent a significant population with a demonstrated need for coordinated support. Patient navigation has a primary focus on: facilitating access to and connection amongst fragmented systems; as well as the provision of educational and emotional support. Given the distinct needs of children with ND and their families, programs built upon such core concepts could be of great benefit. The diversity of terminology encompassing navigation-related concepts and activities (e.g., care coordination, case management, family support), however, presents challenges to both practice and research. This scoping review examined the terminology and descriptions provided within published articles on navigation-type models for children with ND and their families.Methods: The scoping review was conducted according to the Joanna Briggs Institute methodology. A preliminary search was completed on PubMed (NCBI), MEDLINE (Ovid) and CINAHL (EBSCO) to identify initial search terms, upon which a full search strategy was developed and executed in MEDLINE (Ovid) and CINAHL (EBSCO). After screening records according to our inclusion and exclusion criteria, a full-text review of relevant articles was conducted and data extracted using a researcher-developed tool. Under close supervision by the research team, study selection was primarily performed by one author.Results: Of the 2597 papers identified, 33 were included in the final review. From the included papers, a total of 49 terms were extracted, 20 of which were unique. Across the diversity of terminology observed, articles provided detailed and rich descriptions characterized by four central domains, namely: (i) what navigation-related resources, supports and services aim to facilitate and (ii) provide; (iii) descriptions of their intended outcomes; as well as (iv) guiding principles.Conclusions: This scoping review addresses a gap in our knowledge related to the specification of patient navigation and related supports as applied to the specific context of children with ND and their families. Given the particular needs of this population, we propose an empirically-informed integrative model that synthesizes the findings from this scoping review. We suggest that this framework can be used as a guide to the mindful characterization of how supports aiming to connect children and families to needed service are termed and described within future research and in practice.

Recovered papers contain several chromophores, such as wood lignin and dyes. These have to be eliminated during paper recycling in order to produce white paper. Hydrogen peroxide under alkaline conditions is generally used to decolorize lignin, but its effect on dyes is limited. Copper(II)-phenanthroline (Cu-Phen) complexes can activate the oxidation of lignin by hydrogen peroxide. Hydrogen peroxide may also be activated during recycled fiber bleaching, thus enhancing its color-stripping efficiency towards unoxidizable azo dyes. The purpose of this paper was to determine the effect of Cu-Phen complexes on a model azo dye, Direct Red 81 (DR81), in aqueous solution. Different Cu-Phen solutions (with different initial Cu:Phen molar ratios) were prepared and mixed with the dye at different pHs. The geochemical computer program PHREEQC allowed precise calculation of the theoretical distribution between different possible coordinates (CuPhenOH+, Cu(Phen)22+, CuPhen(OH)2, Cu(Phen)32+, etc.) depending on pH and initial concentrations. UV-vis spectroscopic measurements were correlated with the major species theoretically present in each condition. The UV absorbance of the system was mainly attributed to the Cu-Phen complex and the visible absorbance was only due to the dye. Cu-Phen appeared to reduce the color intensity of the DR81 dye aqueous solution under specific conditions (more effective at pH 10.7 with Cu:Phen = 1:1), probably owing to the occurrence of a coordination phenomenon between DR81 and Cu-Phen. Hence, the ligand competition between phenanthroline and hydroxide ions would be disturbed by a third competitor, which is the dye molecule. Further investigation proved that the DR81 dye is able to form a complex with copper-phenanthroline, leading to partial color-stripping. This new “color-stripping effect” may be a new opportunity in paper and textile industries for wastewater treatment. [ABSTRACT FROM AUTHOR]

This paper investigates how interprofessional emergency teams manage to achieve simultaneous start (and end) of a joint activity by counting "one, two, three" as a 'projection device' during drills of mass casualty incidents (MCIs). Situations are analyzed in which they move an (simulated) injured person onto a stretcher either because the person is trapped under a car or is transferred to a stretcher in the emergency hospital. Counting allows the participants to synchronize several actions, carry out last-minute adjustments, and perform a coordinated action simultaneously, here, on "three." This is achieved in situations with limited visibility, via the rhythm of counting, and the list organization of the number sequence "One, two, three." This possibility of projecting relatively precisely the starting point of the joint action contrasts with situations in which counting "One, two, three" is instead used as an orientational frame that suggests the start of the action sometime after "two." • Counting "One, two, three!" is investigated as a phenomenon of micro-coordination in interprofessional emergency teams.. • Counting "One, two, three!" is a practice for organizing and projecting a simultaneous start and end of coordinated actions. • Conditions for the projection device to be functional: ad hoc teams, time pressure, not harm persons, limited visual access.. • SIt is part of a sequential interactional pattern: announcement, focusing/checking, initiation, coordinated action, comments. • Projective potential for the start : announcement, list/enumeration, establishment of a recognizable rhythm via two beats. • Projective potential for the end : prosodic contour contributing to project the lengths and thus the endpoint of the action. • "Two" is a pivotal point: it allows for precisely timed last-minute adjustments and interruptions by team leader/members. • Sometimes, counting "one, two, three" is used only as an orientational frame which points to effects of intercorporeality.
