Abstract

Purpose

The purpose of this paper is to study the reliability of sintered nano-silver joints on bare copper substrates during high-temperature storage (HTS).

Design/methodology/approach

In this study, HTS at 250 °C was carried out to investigate the reliability of nano-silver sintered joints. Combining the evolution of the microstructure and shear strength of the joints, the degradation mechanisms of joints performance were characterized.

Findings

The results indicated that the degradation of the shear properties of sintered nano-silver joints on copper substrates was attributed to copper oxidation at the silver/copper interface and interdiffusion of interfacial elements. The joints decreased by approximately 57.4% compared to the original joints after aging for 500 h. In addition, severe coarsening of the silver structure was also an important cause for joints failure during HTS.

Originality/value

This paper provides a comparison of quantitative and mechanistic evaluation of sintered silver joints on bare copper substrates during HTS, which is of great importance in promoting the development of sintered silver technology.

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

Abstract

Purpose

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

Design/methodology/approach

The sensor structure is formed by a long period fiber grating cascaded with a section of thin-core fiber. The long period fiber grating is fabricated on single mode fiber, followed by a section of 20-mm length thin-core fiber which is a modal interferometer.

Findings

Cladding mode interference between long period fiber grating and thin-core fiber modal interferometer is weak in the experimental investigation. Both of these two cladding mode type fiber devices are sensitive to surrounding RI and temperature. So the RI and temperature can be measured simultaneously by monitoring the spectral characteristics of the compound sensor. The sensitivity is calibrated and sensor matrix is provided in the experiment.

Originality/value

This proposed fiber sensor is simple, tough, cost-effective and suitable for discriminate the liquid RI and temperature with high sensitivity.

Abstract

Purpose

This paper aims to study the effect of isosceles triangle micro concave texture with different parameters on the performance of oil seal to obtain a reasonable combination of parameters.

Design/methodology/approach

Based on the theory of elastohydrodynamic lubrication, a numerical model is established by coupling the texture parameters of isosceles triangle with concave lip with the two-dimensional average Reynolds equation considering surface roughness.

Findings

The results show that there is an optimal combination of parameters to improve the performance of the oil seal. When hp = 5µm-6.5 µm, a = 110°−130°, O = 1.4, C = 1.6 mm-2.2 mm, the oil seal with isosceles triangle micro concave texture can show good lubrication characteristics, friction characteristics and sealing ability.

Originality/value

The model provides a new idea for the design of new oil seal products and provides a theoretical support for the application of surface texture technology in the sealing field in the future.

Abstract

Purpose

Following Hovland’s persuasion theory, this paper aims to develop a conceptual model and analyzes characteristics of online political deliberation behavior from three aspects (i.e. information, situation and manager). Based on the whole interactive process of online political deliberation, this paper aims to reveal the key points that affect the response effect of the government from the persuasive perspective of online political consultation.

Design/methodology/approach

Based on more than 40,000 netizens’ posts and government responses from 2011 to the first half of 2019 of the Chinese political platform, this paper used the text analysis and machine learning methods to extract measurement variables of online political deliberation characteristics and the econometrics analysis method to conduct empirical research.

Findings

The results showed that the textual information, political environment and identity of the political objects affect the effectiveness of government response. Furthermore, for different position categories of political officials, the length of political texts, topic categories and emotional tendencies have different effects on the response effectiveness. Additionally, the effect of political time on the effectiveness of response differs.

Originality/value

The findings will help ascertain the characteristics of online political deliberation behavior that affect how effective government response is and provide a theoretical basis for why the public should express their political concerns.

Abstract

Purpose

The purpose of this paper is to report the results of a qualitative study exploring the conditions associated with the creation, preservation and transmission of Shuishu archives in China, and the crises today in their preservation and transmission and the reasons behind them. It also proposes activation mechanisms to shift Shuishu archives from jeopardized collective memory to preservable cultural memory.

Design/methodology/approach

Semi-structured interviews and ethnographic fieldwork were conducted over the course of a month in 2015.

Findings

The creation, preservation and transmission of Shuishu archives in the community of the Shui rely upon the community’s closed system. But this system has been broken as a result of modernization and wide use of new media in China. To preserve and transmit Shuishu archives to future generations, there needs to be mutual trust and equitable cooperation between government archives and the Shuishushi. The “cultural consciousness” of the Shui needs to be stimulated, and more members of the Shui and the whole of society need to participate in the preservation and transmission of this distinctive memory.

Practical implications

The study can provide a provocative example for education in preservation and LIS about community culture and archiving, and the preservation of social memory, identity and culture. The activation mechanisms seek to aid in the preservation and transmission of Shuishu archives and other similar community memory.

Originality/value

The study uses semi-structured interviews and ethnographic methodology to develop a rich understanding of the history and the status quo of the preservation and transmission of Shuishu archives. It redefines Shuishu archives and sheds light on the roles government archives should play in the preservation and transmission of Shuishu archives.

Abstract

Purpose

The purpose of this paper is to provide a brief yet insightful survey of papers in the first issue of Chinese Management Studies. In the process, the founding Editor focuses on the key concepts and how scholars may further extend and build on the research undertaken.

Design/methodology/approach

The Editor provides a snapshot of the research undertaken in the papers selected for this issue. Instead of simply summarizing the work undertaken, the Editor, where it is highly appropriate, incorporates aspects of underlying Chinese culture. For instance, how the Confucian concept of the doctrine of mean – very broad as it is in scope – is supported in research reported here. Also, in contradiction to what authors may have argued on meaningfulness of work per se, to highlight an old Chinese adage: for example, 工字不出头 (gong-zhi-bu-chu-tuo). A literal translation into English will fail to render the true intent of the phrase. What it means is that the Chinese character for “work” implies a much deeper meaning: The horizontal line on top of the vertical limits the potential of future growth. Other concepts are visualized for ease of readers grasping the key concepts.

Findings

The series of papers here highlight the significance of research into managerial behaviors (negatively, tax aggression and abuse of power for self-enrichment), meaningfulness of work, reading of timeless Chinese novels, innovation (ZTE) and the knowledge organization, changing and transforming China and of Russian-Chinese (Taiwan) strategic alliances. The insights gained through these intensive research efforts ought to be shared with scholars globally.

Social implications

The research in this issue has wide practical relevance as in highlighting the critical importance of a range of topics: Jiang Hu organizing theory, managerial behaviors, innovation and knowledge, Russo-Chinese strategic alliances, fit in strategic management and China-in-transition. This paper ties these together for the reader.

Originality/value

Through a review of these papers, the Editor provides insights for scholars on the possibilities for extending the frontiers of research on Chinese management. Where relevant the Editor highlights additionally, perspectives from deeply rooted Chinese beliefs, values and philosophy.

Abstract

Purpose

The integration of the digital economy and the real economy has been a key focus in promoting digital economic development. It denotes a comprehensive digital transformation of national economic activities regarding technological infrastructure and production modes, which is crucial for establishing a modern economic system, advancing industrial infrastructure and modernizing industrial chains.

Design/methodology/approach

Firstly, the study delves into the internal logic behind the emergence of the new development dynamic resulting from digital technology's evolution. Secondly, it explores the mechanism of mutual promotion and support between the new development dynamic and the digital economy based on China's shift in focus from international engagement to the domestic economy during different stages of industrialization. Subsequently, it analyzes the characteristics and critical factors of digital economy development and examines the macro-, meso- and micro-level constraints on these factors. Finally, the paper explores approaches to promoting digital economy development while constructing the new development dynamic and provides relevant policy suggestions.

Findings

The construction of the new development dynamic and the development of the digital economy are inextricably linked, and only by mutually reinforcing each other can they provide an inexhaustible impetus for China's high-quality economic development.

Originality/value

The new development dynamic and the digital economy development form an indivisible whole. The new development dynamic creates the necessary conditions for digital economy development and promotes the formation of digital production modes. In turn, the development of the digital economy should strive to improve the mainstay position of the domestic economy, enhance the synergy between the domestic economy and international engagement, upgrade value chains while improving the supply and the industrial chains in China and ensure a parallel increase in labor income alongside improved productivity.

This paper aims to identify how house price affects household consumption.

Abstract

Purpose

This paper aims to identify how house price affects household consumption.

Design/methodology/approach

The authors use a micro-level data set that tracks the house price and consumption of a vast number of households over a period of four years. OLS regression is the main econometric method.

Findings

The authors document robust evidence that an increase in house prices stimulates household consumption, regardless of whether a household owns or rents. Moreover, the authors find that both acquiring and losing homeownership negatively affects household consumption. Further investigation suggests significant regional heterogeneity in the relationship between house prices and household consumption.

Originality/value

This is one of the first studies examining the relationship between house price and household consumption in China using micro-level data. Given the uniqueness of the Chinese housing market and China’s fast-growing consumption rate, the study contributes new evidence to the long-lasting debate.

Abstract

Purpose

The purpose of this paper is to examine how corporate and nonprofit leaders partner on public relations for corporate social responsibility (CSR) programs.

Design/methodology/approach

Through semi-structured interviews across the USA, and stretching into Europe and South America, leaders (n=24) from US-based corporations top-ranked for corporate citizenship, and the nonprofit organizations with which they have developed CSR programs, shared insights and best practices.

Findings

Corporate and nonprofit leaders who collaborate on CSR programs spoke independently about several essential shared values, including community-focused collaboration, fiscal responsibility, and strategic alignment. How they described their CSR partnerships reflects a mutual commitment to a distributed leadership model, which involves the need to span organizational boundaries, share unique expertise across levels and roles, and sustain long-term relationships. Consistent with prior research, this study also suggests that communication leaders in both corporations and nonprofit organizations leverage transactional (process-focused) and transformational (people-focused) leadership styles, as they work to build and foster these long-term partnerships.

Research limitations/implications

The findings pinpoint how principles of the distributed leadership model come to life across CSR partnerships and contribute to the success of such partnerships. Corporations and their nonprofit partners must mutually focus on spanning, sharing, and sustaining as they build programs together. These shared principles exemplify a distributed leadership model and help define what CSR partnership truly means.

Originality/value

This study looks at CSR programs beyond just the perspective of the corporation and the public, taking into account the critical role the nonprofit organization plays as a partner in some CSR programming, and within a distributed leadership model.

Abstract

Purpose

The purpose of this paper is to present age-based replacement models subject to shocks and failure rate in order to determine the optimal replacement cycle. As a result, according to system reliability, maintenance costs of the system are to be minimized.

Design/methodology/approach

First, the modeling with respect to assumptions and two major factors (shocks and failure rate) is done. Second, by using of MATLAB the optimal parameters are obtained. Finally, analysis of results and comparison of models are done.

Findings

Analysis of results shows all models provide optimal replacement cycle and at this time, cost rate of the system by considering the reliability rate is minimal. Also with an increase of one unit to two units, reliability rate increases much higher than the rate of cost.

Originality/value

This work provides models that in addition to considering the failure rate (internal factors), also shocks as an external factor have been considered. By considering these two factors more comprehensive and adaptable models have been proposed.
