This paper aims to forecast the future development of UIC technology according to the changes of IPC in different time periods. The findings also provide a theoretical basis for the UIC policymakers of energy-saving environmental protection industry.

The present study will take energy-saving technology as an example, through using a two-mode network analysis method to build the four-stage IPC code UIC innovation-technology network, researching UIC innovation network applicant heterogeneity, UIC technology network and technology relevance.

Through the establishment of UIC innovation-technology two-mode network, namely, applicant node CN and IPC node TN, this paper analyzes the important applicants, focal technologies, correlation of focal technologies and the development trends of energy saving technology in the future by using the related theories and methods of two-mode network.

At present, only about 11% of energy-saving enterprises in China have R&D activities. The government needs to implement top-level design, improve industrial policies, strengthen investment in technology R&D and build a platform for technological innovation in energy-saving industries to support the R&D of common and key technologies in energy-saving industries.

We often hear questions like “What must that leader have been thinking?” “What possessed her to do that?” “That leader needs to give his head a shake!” or “It is so disappointing to see the pain caused by one wrong-headed and self-serving leader!” This chapter describes how leaders may subtly fall into rationalization, self-justification, foolishness, and callous indifference through maleficent internal narratives. How is it that leaders who have found the favor of others in the service of a great cause (i.e., the education of children and youth) find themselves sucked into clearly wrong or unthinkably bad actions? In this chapter, vicious (non-virtuous) thinking, inner political churnings, unconscious reinforcement of systemic evil, and hurtful ways of influencing others are explored, named, and challenged.

This study aims to investigate the differential roles of self-esteem and co-rumination in the mediated relationship between abusive supervision and knowledge hiding via psychological safety.

The study used a three-wave time-lagged design and data were collected from 388 full-time employees in India.

The results show that psychological safety mediated the impact abusive supervision had on knowledge hiding. Further, this impact was weakened by higher self-esteem as employees with higher self-esteem were less affected by the impact of abusive supervision on psychological safety and knowledge hiding; but this impact was amplified by more co-rumination as employees who co-ruminated more were also more affected by abusive supervision in psychological safety and knowledge hiding.

A cross-sectional design and the use of self-reported questionnaires are a few limitations of this study.

This study took a purposeful deviation from the traditional path of organizational justice to the study of abusive supervision and psychological safety and endeavored an alternate route, one of resource conservation. Further, employees have diverse reasons that heighten or dampen their inclination to hide knowledge from others in the workplace. The study examines co-rumination and self-esteem as possible boundary conditions.

The purpose of this paper is to critically review the existing research on the intersection between war and international business (IB) and to map out a future research agenda.

Drawing on corporate examples and extant literature within IB, political science and international relations, the paper provides an introduction to the main concepts of war, a review of the IB research on war and provides a critical future research agenda.

The review of the multiple strands of war-related research in IB generally reveals an understudied area. Among other biases, prior research has focused on inter-state wars and has relatively unexplored foreign direct investment (FDI) and non-FDI within civil wars. Furthermore, previous studies offer little attention to how IB and multinational companies contribute to the emergence and development of wars.

The paper develops an analytical and critical research agenda for future research to examine the relationship between war and IB. This includes a set of questions for each of the three major phases of war: pre-conflict, armed violence and post-conflict. To the best of my knowledge, this has not been done before in the context of IB research.

The purpose of this paper is to investigate the relationship between housing finance institutional related variables and financial related variables of low-income earners in Bauchi Local Government Area, Bauchi, Nigeria.

In this study, quantitative research approach was adopted. Self-administered structured questionnaires were used to collect information from 500 primary school teachers in Bauchi Local Government Area, Bauchi, Nigeria. A correlation analysis was carried out to find the relationship between housing finance institutional contexts and finance contexts to low-income earners in the study area using SPSS Version 23 software.

The findings shows that the low-income earners were more concerned with the accessibility and affordability on housing ownership, and it also showed that performance and effectiveness of the housing finance institutions were of paramount importance to housing ownership for the low-income earners in the study area.

The finance institutions are the prime consumer of these research findings. The participants in the finance institutions are going to benefit from the low-income earners’ housing ownership development.

The paper also emphasized that the finance institutions should make the housing finance loan accessible and affordable to the low-income earners to meet their dream to sustainable housing ownership.

This study aims to analyse the association between country-level ethical judgement and earnings management and the role that firm-level enforcement and the quality of accounting standards play in this association.

The analyses are based on a sample of 45,889 firm-year observations from 34 countries between 1998 and 2018. Based on the World Values Survey questionnaire, this study constructs a comprehensive index of the ethical judgement of each country.

The empirical findings suggest that firms from countries where ethically suspect behaviours are less acceptable are associated with lower levels of accruals-based earnings management and that firm-level enforcement and the quality of accounting standards dampen such association.

The results contribute to the debate about ethical issues in the accounting profession in an international context, adding to the sustainable development debate given that the creation of long-term value for firms is intrinsically related to business ethics and good quality financial reporting.

When it is known that countries’ ethically-related judgements reduce the level of earnings management, actions can be taken by regulators and other stakeholders to build fairer societies with a more sustainable view, given that the quality of the financial reporting is inextricably linked to how income and wealth are distributed.

While previous literature documents that ethical judgement at both the individual and organizational levels matter as key determinants of the way managers are involved with unethical accounting practices, this study investigates the role of ethical judgement at the country level in explaining earnings management.

The purpose of this study is to use the corrected stress field theory to derive the shear capacity of geopolymer concrete beams (GPC) and consider the shear-span ratio as a major factor affecting the shear capacity. This research aims to provide guidance for studying the shear capacity of GPC and to observe how the failure modes of beams change with the variation of the shear-span ratio, thereby discovering underlying patterns.

Three test beams with shear span ratios of 1.5, 2.0 and 2.5 are investigated in this paper. For GPC beams with shear-span ratios of 1.5, 2.0 and 2.5, ultimate capacities are 337kN, 235kN and 195kN, respectively. Transitioning from 1.5 to 2.0 results in a 30% decrease in capacity, a reduction of 102kN. Moving from 2.0 to 2.5 sees a 17% decrease, with a loss of 40KN in capacity. A shear capacity formula, derived from modified compression field theory and considering concrete shear strength, stirrups and aggregate interlocking force, was validated through finite element modeling. Additionally, models with shear ratios of 1 and 3 were created to observe crack propagation patterns.

For GPC beams with shear-span ratios of 1.5, 2.0 and 2.5, ultimate capacities of 337KN, 235KN and 195KN are achieved, respectively. A reduction in capacity of 102KN occurs when transitioning from 1.5 to 2.0 and a decrease of 40KN is observed when moving from 2.0 to 2.5. The average test-to-theory ratio, at 1.015 with a variance of 0.001, demonstrates strong agreement. ABAQUS models beams with ratios ranging from 1.0 to 3.0, revealing crack trends indicative of reduced crack angles with higher ratios. The failure mode observed in the models aligns with experimental results.

This article provides a reference for the shear bearing capacity formula of geopolymer reinforced concrete (GRC) beams, addressing the limited research in this area. Additionally, an exponential model incorporating the shear-span ratio as a variable was employed to calculate the shear capacity, based on previous studies. Moreover, the analysis of shear capacity results integrated literature from prior research. By fitting previous experimental data to the proposed formula, the accuracy of this study's derived formula was further validated, with theoretical values aligning well with experimental results. Additionally, guidance is offered for utilizing ABAQUS in simulating the failure process of GRC beams.

Island attack and defense, emergency rescue, scientific research, civilian fisheries and other fields are inseparable from timely, high-quality underwater communications. However light and other electromagnetic waves are severely attenuated in water, acoustic is currently the only energy carrier that can transmit signals over long distances in water. However, the complex water environment and serious interference bring serious challenges to underwater activities using underwater acoustic sensors-hydroacoustic transducers. Thus, this paper aims to develop a class of high reception sensitivity hydroacoustic transducer structures to provide research and utilization ideas for related scholars.

The electromechanical coupling coefficient is improved by converting the thickness vibration mode of the piezoelectric ceramic into the longitudinal vibration mode of the piezoelectric pillars array, and no polymer is added between the piezoelectric pillars array to reduce lateral coupling as well as internal friction, which can thus reduce the energy losses. Radial stacking in parallel can also enhance the charge generated through the positive piezoelectric effect. The optimal parameters of the structure are determined by equivalent circuit method and finite element analysis, and a hydroacoustic transducer of this structure is fabricated finally.

According to the standard test procedure, the hydroacoustic transducer was tested in water. The tests show that the conductance curve of the stacked high-sensitivity hydroacoustic transducer tested in the air is in good agreement with the simulation results. The resonant frequency is about 118 kHz, and the receiver sensitivity is −166 dB. The stacked material hydroacoustic transducer is in the high-frequency range and has a much higher sensitivity (−166 dB) than many types of hydroacoustic transducers fabricated by piezoelectric ceramic (less than −200 dB).

Although the stacked high-sensitivity hydroacoustic transducer that the authors have fabricated has a performance improvement, it has a limitation. The hollow design of the pillar arrays increases the reception stress on each pillar, and the imposed pressure comes from water also increases simultaneously, so the depth of water that the stacked high-sensitivity hydroacoustic transducer can operate in may be slightly shallower than that made of a pure piezoelectric ceramic block or a piezoelectric ceramic material with polymer added. This will be a problem to be solved in a future deployment.

Whether it is marine scientific research or in various fields such as civil recreation and fishing, hydroacoustic communication and necessary underwater exploration are indispensable for acoustic waves. The hydroacoustic transducer is the sensor that sends and receives sound waves, so a lot of water equipment, such as yachts, sonar buoys, and so on, cannot be separated from the hydroacoustic transducer. In addition, the complexity of the water environment also requires a good performance of the hydroacoustic transducer to facilitate the convenience and effectiveness of subsequent signal processing. Therefore, hydroacoustic transducers have great market and commercial value.

Hydroacoustic transducers are not only of great commercial value but also have a significant impact on the military as well as on people’s livelihood. As we all know, in the area of submarine communication and underwater exploration, sonar is the main force. The performance of the hydroacoustic transducer directly affects the performance of the hydroacoustic signal processing system, and ultimately directly determines the success or failure of the mission. In addition, the large-scale replacement of hydroacoustic transducers on equipment requires the concerted efforts of a large number of practitioners, such as material scientists, structural scientists, mathematicians and so on. Therefore, the rise of hydroacoustic transducers has given rise to a large number of learning positions as well as employment positions.

To enhance the reception sensitivity of the hydroacoustic transducer, the authors have optimized the existing hydroacoustic transducer materials and structures to propose a stacked sensitive element, which can effectively enhance the electromechanical conversion coefficient of the piezoelectric material. Furthermore, the authors have manufactured a hydroacoustic transducer using the proposed stacked sensitive element. The test results of the hydroacoustic transducer also show that the designed stacked sensitive element is of great help to enhance the reception sensitivity of the hydroacoustic transducer.
