Qualitative analysis of the coupling effect of fluid velocity distribution in microchannels on the performance of water-cooling lithium-ion batteries system

ABSTRACT Lithium-ion batteries are the direct power sources of electric vehicles, but their high heat flux density restricts their development. Microchannel heat sinks (MCHS) can assist in heat dissipation to overcome this. The distribution of fluid velocity among microchannels has a considerable effect on the performance of MCHS for a water-cooling lithium-ion batteries system. In this paper, a new microchannel heat sink with high depth to width aspect ratio is proposed and the influence of four different aspect ratios on the distribution of fluid velocity among microchannels and heat transfer performance of MCHS was numerically studied by computational fluid dynamics (CFD). The results showed that at the same inlet flow rate, the larger the aspect ratio of the microchannels, the better the uniformity of the internal fluid velocity. The heat performance of microchannel structures with four different aspect ratios for a water-cooling lithium-ion batteries is further investigated experimentally. Compared with the simulation results of the fluid velocity distribution, the coupling effect between the fluid velocity distribution in the microchannels and the heat dissipation performance of a water-cooling lithium-ion batteries is analyzed. The results fully demonstrated that a larger aspect ratio of the microchannels results in a better heat dissipation performance on the surface of the lithium-ion batteries. Optimizing the aspect ratio of the microchannels to facilitate a relatively uniform velocity distribution to improve heat dissipation performance of the water-cooling system may be a key factor to be considered, which provides a new idea for passive thermal management of batteries.

Self-Powered, Flexible, Wireless and Intelligent Human Health Management System Based on Natural Recyclable Materials.

Combining wearable sensors with modern technologies such as internet of things and big data to monitor or intervene in obesity-induced chronic diseases, such as obstructive sleep apnea, type II diabetes, cardiovascular diseases, and Alzheimer's disease, is of great significance to the self-health management of human beings. This study designed a loofah-conducting graphite four friction layer enhanced triboelectric nanogenerator (LG-TENG) and developed a health management system for human motion recognition and early warning of sleep breathing abnormalities. By uniformly spraying and depositing conductive graphite on the surface of the loofah and the elastic film cross-interlocking bending structure design, the signal strength of the LG-TENG has been improved by 390%. The stable output signal is still maintained after 1500 s of continuous operation at a frequency of 2 Hz. LG-TENG can realize accurate motion analysis by muscle contraction state. Combining different deep learning models resulted in 98.1% accuracy in recognizing seven categories of displacement speeds for an individual and 96.46% accuracy in recognizing seven categories of displacement speeds for three individuals. In addition, the sleep breathing monitoring early warning system was developed by integrating Bluetooth wireless transmission and upper computer analysis technology. This system aims to analyze and provide real-time warnings for sleep-breathing abnormalities. This research promotes an innovation of TENG technology based on the advantages of natural materials, recyclability and low cost. It offers new ideas for self-health management and scientific exercise for obese people, showing a broad application prospect.

It Takes a Village: Translating Management Ideas through an Ecology of Roles

AbstractAlthough research has provided valuable insights into how management ideas circulate across contexts and undergo translation, the prevailing focus remains on the one‐directional journey from idea suppliers to adopting entities. In contrast, we advance an ecology of roles perspective to capture the dynamic relationships between multiple actors and roles in the translation process. To develop our argument, we draw from a 10‐year case study examining how the US‐born management idea of the leadership pipeline was translated into a domesticated version in Denmark, which became widely adopted but also contested and renewed. In analysing this case, we show how the same actors assumed an array of interdependent roles that dynamically shifted over time to circulate the idea. We identify three characteristics of an ecology of translation roles: multiplicity of roles, morphing of roles, and reciprocal authorization of roles. By advancing an ecology of roles perspective, our study contributes novel insights to the expanding literature on translation and recent work on translation ecosystems.

How intelligence organisations innovate

ABSTRACT Practitioners and academics recognize the importance of innovative intelligence organisations. However, we know little about how intelligence organisations innovate and what challenges they are being confronted with. Drawing upon intelligence studies as well as innovation and organisational studies this paper forwards a conceptual framework to answer the question: how do intelligence organisations innovate? To address this, we introduce the concept of innovation capability, an organisation’s potential to innovate. The paper identifies seven attributes of innovation capability and explores these attributes within intelligence organisations. The attributes are: (1) vision and strategy, (2) competence base, (3) organisational intelligence, (4) creativity and idea management, (5) organisational structure, (6) culture and climate and (7) management of technology. The paper concludes with an agenda for further research.

Phosphogypsum with Rice Cultivation Driven Saline-Alkali Soil Remediation Alters the Microbial Community Structure.

The improvement of saline-alkali land plays a key role in ensuring food security and promoting agricultural development. Saline soils modifies the response of the soil microbial community, but research is still limited. The effects of applying phosphogypsum with rice cultivation (PRC) on soil physicochemical properties and bacterial community in soda saline-alkali paddy fields in Songnen Plain, China were studied. The results showed that the PRC significantly improved the physicochemical properties of soil, significantly reduced the salinity, increased the utilization efficiency of carbon, nitrogen, and phosphorus, and significantly increased the activities of urease and phosphatase. The activities of urease and phosphatase were significantly correlated with the contents of total organic carbon and total carbon. A redundancy analysis showed that pH, AP, ESP, HCO3-, and Na+ were dominant factors in determining the bacterial community structure. The results showed that PRC could improve soil quality and enhance the ecosystem functionality of soda saline-alkali paddy fields by increasing nutrient content, stimulating soil enzyme activity, and regulating bacterial community improvement. After many years of PRC, the soda-alkali soil paddy field still develops continuously and healthily, which will provide a new idea for sustainable land use management and agricultural development.

Research and application of the method of measuring the effective utilization coefficient of irrigation water on farmland

Abstract Under the guidance of the new water management idea of “water conservation priority, spatial balance, system management, and two-handed effort,” the National Water Conservation Action Plan released in 2019 puts forward the key task requirements of “double control of total intensity,” in which the effective utilization coefficient of irrigation water in farmland is one of the indicators of water intensity control. The effective utilization coefficient of irrigation water is one of the water intensity control indicators. At present, there are practical difficulties in measuring the effective utilization coefficient of irrigation water in farmland, such as the low measurement rate of water consumption in the current irrigation area, the high input equipment and manpower requirements, and the difficulty in accurately measuring the net irrigation water absorbed by crops. Therefore, this paper proposed the method of “field monitoring - remote sensing inversion - a comprehensive analysis of data.” The method of “field monitoring - remote sensing inversion - econometric model construction - comprehensive analysis” was proposed in this paper, which can obtain gross irrigation water utilizing field monitoring, overcome the difficulty of accurate monitoring of net irrigation water using remote sensing, and carried out a comprehensive analysis, to realize the scientific, effective and rapid calculation of effective utilization coefficient of irrigation water. This method was applied to the Meixian District, Guangdong Province, and the research results show that it not only generates reliable measurement data but also alleviates workload. Furthermore, it offers scientific measurement techniques for water use efficiency indicators, facilitating the achievement of “dual control over total volume and intensity.” This paper provides an important technical basis for the rational allocation of water consumption and scientific approval of water use plans and supports the assessment of the effectiveness of water-saving irrigation development and the reasonable evaluation of the water-saving potential of farmland irrigation, thus providing a basis for local government departments at all levels to make planning, scientific decision-making, and macro-management.

Ретроспективный анализ научных взглядов о государственно-общественном управлении образованием на материале eLibrary.ru

Introduction. Since 2000 up. to the present time, there has been an increase in scientific and applied public interest in the role of state and public education management (SPEM). This period is associated with a change in scientific, pedagogical and management ideas in SPEM, which allows for a retrospective analysis of scientific views on the problem, based on publications in the Russian scientific electronic library eLibrary.ru for the specified period. The purpose is to study and summarize scientific views on the state and public management of the education system in our country for the period 2000-2024 to determine further littlestudied directions for the development of state educational institutions. Materials and methods. Using a retrospective analysis of publications from the Russian scientific electronic library eLibrary.ru, recognizing and describing the stages of publication activity of Russian researchers on the problems of state-public education management, which are associated with the stages of development and implementation of the SPEM reform, are named. Based on a comparative analysis, the theoretical foundations of the organization of SPEM in the Russian Federation, general and specific approaches to the practical organization of SPEM at the regional and national level, and modern views on the topic were identified. Results. Systematization of information made it possible to identify the current state of knowledge of the problem, and to determine possible directions for further research of SPEM in the Russian education system. A three-stage periodization of scientific research into the SPEM model in Russia is proposed. Conclusions are drawn about the validity of the proposed periodization, and the problems of implementing state-public educational management at the present stage, little studied in the scientific literature are noted. Among the problems of implementing state education educational institutions that have been little studied in the scientific literature at the present stage, the following are noted: modern forms of management of an educational organization in the conditions of state education educational institutions, the potential of state educational institutions for the civil and patriotic education of students, features of the development of the digital educational space of school self-government in the state education educational institution system, mentoring technologies in working with schoolchildren in conditions of state and public school management.

Evaluating the Effect of Implementing an Integrated Management Approach During the Transition of a Scientific and Practical Institution to the Performance of R&D Projects

The research objective was to evaluate the effect of implementing a set of management decisions during the transition of a scientific and practical institution from research to R&D projects. We carried out a longitudinal sociological study using the double-survey method. The survey was conducted before and after the implementation of a structured set of systemic measures to improve the efficiency of R&D activities. We have implemented this set because of the transition of our institution from the stage of research work to the stage of both research and development projects. Ideas of matrix and participative management were included in this set of measures. The survey assessed employees’ awareness of the 2023–2025 R&D plan, their needs to implement the plan and job satisfaction score as well as the level of their understanding of risks and their impact on the possibility to fulfill the plan. Due to the deployment of a set of systemic measures, employees’ awareness of participation in the R&D plan implementation increased from 73.6% to 90.0%, and their awareness of the plan’s content grew from 50.0% to 76.0%. A consequence of the implementation of participative management was that employees became aware of their needs to fulfill the plan as well as of the risks of not reaching its targets. Their satisfaction with the plan implementation conditions increased from 69.0% to 77.0% and the confidence in the possibility to implement the plan successfully grew from 55.0% to 92.0%. Matrix management allowed for a timely assessment of the organization’s future needs and increasing the research staff. This resulted in meeting the 2023 targets. Long-term planning of research work is a necessary component for the development of a scientific and practical institution, the organization of knowledge-intensive production and the reduction of the time between the acquisition of new knowledge and the creation of products and technologies and their entry into the market. The uniquely designed set of systemic measures increases not only the efficiency of research work, but also the performance of the employees, promotes their professional development and creates conditions for their personal advancement.

Mapping data-driven management in accounting: the premise and promise of the debate and how to move beyond

Purpose This paper aims to point to the shift in the temporal orientation, going from reporting on the past to creating insights about the future, which might be suggestive of perennial managerial attempts to push the boundaries of bounded rationality. Design/methodology/approach In this essay, the authors want to critically engage with the concept of “data-driven management” in the context of digitalization. To do so, they sketch the edges of current discourses around the emerging idea of data-driven management and its relationship with the inner workings of organizations from an accounting perspective. They question the often-times supposed objectivity and increased rationality of the concept and instead introduce the idea of becoming “data-curious” (before being data-driven). Findings The authors observe that this push also seems to be accompanied by trends of individualized decision-making and prevailing hopes of technology to solve organizational problems. They therefore suggest that it is valuable for current debates to take a moment to give attention, in practice and in research, to the role of temporality, benefits of collective decision-making and changes in professions (of accountants). Originality/value The aim of this paper is to spark curiosity and engagement with the phenomenon of data-driven management by outlining a novel set of potential future pathways of research and point towards methods that might help studying the questions arising for a data-curious approach.

Current compliance challenges and how to address them from an expert perspective

Compliance departments face a variety of challenges in these days. Constantly new legal requirements and new regulations give an idea of the problems compliance managers in companies are confronted with. The aim of this paper is not only to analyze the various challenges in the area of compliance, but also how these can be met in practice. The author uses the qualitative research approach of expert interviews and underpins the research with the theoretical derivation using the resource-based view (RBV) and dynamic capabilities approach. The results show that the experts' opinions on the challenges are largely in agreement, while the different ways in which the experts approach the problems suggest that there does not seem to be one right solution for tackling the issues in the future. It is particularly interesting that possible approaches such as "creativity”, “flexibility “and “agility" also correspond with the theoretical derivation of the topic, according to which dynamic capabilities seem to be decisive for companies' competitive advantage in an ever-changing environment. The paper contributes to a better understanding of the current compliance situation in practice and at the same time points out very interesting new research needs, e.g. how possible solutions to overcome compliance challenges could be implemented.

A dynamic pythagorean exponent: Applications to baseball and structural modeling in risk management

AbstractThe famous Pythagorean theorem relating a team's winning percentage over a season to it's total runs scored and surrendered has been the subject of much attention, in both popular culture and academia. In academia, a main focus has been to find the optimal value for the exponent in the formula, originally taken to be 2 in Bill James' work. The optimal value has been obtained in many published works via regression or other statistical estimation techniques, and calibrated to various sports to reflect the type of play in each sport. In this short article, we borrow from ideas in quantitative finance and risk management to estimate the distribution of these Pythagorean exponents, viewing them as random variables that can evolve over time. We carry out our analysis in a manner similar to that of implied volatility from the Black‐Scholes formula. We present the result of our analysis of 150 years of team data via the Lahman package in R, and also provide dynamic models for an evolving measure of the Pythagorean exponent. This includes suggestions for modeling credit default as well as contract valuation in sports via macro variables in connection with historically implied parameters.

Network governance and reflexivity in fisheries management: a case study of Northern Ireland

ABSTRACT Network governance arrangements, wherein resource users are empowered, are vital for ocean sustainability. These arrangements are critical to implementing innovative practices, particularly those developed to address the negative impacts of top-down management. The adoption of networked governance can foster resource management capacity and equitable decision-making. Research has focused on social ties within networks but has provided a somewhat limited account of how networks evolve to instil novel practices. To implement new practices, networks must engage in reflexive governance. Reflexivity is underpinned by actors’ receptivity to change and network learning. Actors’ receptivity to change relates to whether they acknowledge past failures and how novel management ideas become accepted. Network learning is the degree of change instigated by actors’ reflexive processes. Drawing on the receptivity and network learning theories, and informed by semi-structured interviews, an assessment was conducted on how a fisheries management network in Northern Ireland has reflexively evolved to implement new practices. Findings illustrate that the network has reflexively redesigned how they collaborate, share knowledge, and contribute to policymaking. Demonstrating single– and double-loop learning, these developments have been derived from reflections on the failure of past processes and the instigation of more co-creative processes that benefit all network actors.

The role of OR5, which is highly expressed in the winged grain aphid Sitobion miscanthi, in specific recognition of EBF

Winged parthenogenetic aphids are mainly responsible for migration and dispersal. Aphid alarm pheromone (E)-β-Farnesene (EBF) has dual effects on repelling and stimulating wing differentiation in aphids. Previous studies have shown that the odorant coreceptor SmisOrco is involved in the perception of EBF by S. miscanthi; however, its EBF-specific odorant receptor (OR) and the difference between winged and wingless aphids remain unclear. In this study, the Xenopus oocyte expression system and RNAi technology were used to detect the transmission of EBF signals, and it was found that the olfactory receptor SmisOR5 is an EBF-specific OR in S. miscanthi and is specifically highly expressed in the antennae of winged aphids. Furthermore, when OR5 was silenced with dsRNA, the repellent effect of EBF was weakened, and aphids showed more active aimless movements. Therefore, as a specific OR for EBF, the high expression level of SmisOR5 in winged aphids suggests a molecular basis for its high sensitivity to EBF. This study advances our understanding of the molecular mechanisms of aphid EBF perception and provides novel ideas for effective management and prevention of the migration of winged aphids.

Abstract. The evolution of management ideas has been shaped by advancements spanning from ancient times to the present. Nevertheless, it is widely acknowledged that remnants of historical methods and practices persist in contemporary management approaches. The foundation of numerous management phenomena and theories in the contemporary era has been attempted to be elucidated by drawing upon ideas and practices that may be traced back to previous epochs, including ancient times. This study utilized secondary data and employed a compilation strategy. The objective of the study is to conduct a comparative analysis of the comprehension of management and society in the Sumerian, Egyptian, and Greek civilizations, which hold significant importance in ancient history. An attempt has been made to ascertain how the concept of management was developed in these three civilizations, the reasons that influenced management, and to identify and compare the key characteristics of management in each culture. The study aims to elucidate the disparities in governance and social structure among the three civilizations. The collected data have led to the conclusion that the geography of a civilization's settlement and the cultural and religious values of its society play a crucial role in shaping the system of government.

A new methodology for reducing carbon emissions using multi-renewable energy systems and artificial intelligence

Microgrid cost management is a significant difficulty because the energy generated by microgrids is typically derived from a variety of renewable and non-renewable sources. Furthermore, in order to meet the requirements of freed energy markets and secure load demand, a link between the microgrid and the national grid is always preferred. For all of these reasons, in order to minimize operating expenses, it is imperative to design a smart energy management unit to regulate various energy resources inside the microgrid. In this study, a smart unit idea for multi-source microgrid operation and cost management is presented. The proposed unit utilizes the Improved Artificial Rabbits Optimization Algorithm (IAROA) which is used to optimize the cost of operation based on current load demand, energy prices and generation capacities. Also, a comparison between the optimization outcomes obtained results is implemented using Honey Badger Algorithm (HBA), and Whale Optimization Algorithm (WOA). The results prove the applicability and feasibility of the proposed method for the demand management system in SMG. The price after applying HBA is 6244.5783 (ID). But after applying the Whale Optimization Algorithm, the cost is found 4283.9755 (ID), and after applying the Artificial Rabbits Optimization Algorithm, the cost is found 1227.4482 (ID). By comparing the proposed method with conventional method, the whale optimization algorithm saved 31.396 % per day, and the proposed artificial rabbit's optimization algorithm saved 80.3437 % per day. From the obtained results the proposed algorithm gives superior performance.
