Abstract

Purpose

To reduce the influence of temperature on MEMS gyroscope, this paper aims to propose a temperature drift compensation method based on variational modal decomposition (VMD), time-frequency peak filter (TFPF), mind evolutionary algorithm (MEA) and BP neural network.

Design/methodology/approach

First, VMD decomposes gyro’s temperature drift sequence to obtain multiple intrinsic mode functions (IMF) with different center frequencies and then Sample entropy calculates, according to the complexity of the signals, they are divided into three categories, namely, noise signals, mixed signals and temperature drift signals. Then, TFPF denoises the mixed-signal, the noise signal is directly removed and the denoised sub-sequence is reconstructed, which is used as training data to train the MEA optimized BP to obtain a temperature drift compensation model. Finally, the gyro’s temperature characteristic sequence is processed by the trained model.

Findings

The experimental result proved the superiority of this method, the bias stability value of the compensation signal is 1.279 × 10–3°/h and the angular velocity random walk value is 2.132 × 10–5°/h/vHz, which is improved compared to the 3.361°/h and 1.673 × 10–2°/h/vHz of the original output signal of the gyro.

Originality/value

This study proposes a multi-dimensional processing method, which treats different noises separately, effectively protects the low-frequency characteristics and provides a high-precision training set for drift modeling. TFPF can be optimized by SEVMD parallel processing in reducing noise and retaining static characteristics, MEA algorithm can search for better threshold and connection weight of BP network and improve the model’s compensation effect.

Abstract

Purpose

This paper aims to provide an overview for the main project details of the China Academic Digital Library (CADL) with focused introduction on China Academic Library and Information System (CALIS), China Academic Digital Library and Information System (CADLIS), China‐America Digital Academic Library (CADAL) and China Academic Humanities and Social Sciences Library (CASHL).

Design/methodology/approach

The paper first gives a literary review on CADL and then analyzes the existed and existing problems of China digital library construction using graphical presentation and tabular comparison.

Findings

After reviewing CADL and the major related projects developed in the last decade, it is shown that the digital library (DL) construction effort in China is divided into three phases: concept introduction phase, technical exploration phase, and application deployment phase. The first phase of CADL gave a solid preparation in terms of concept introduction while the DL soon began to be recognized and accepted as a practical proposal among industries. In the second phase, various potential technologies for DL realization were substantially investigated, tested, and implemented. The related projects cover subjects including DL architecture, information retrieval, information description, digitization, e‐Book, Digital Rights Management, etc. During the last phase, standards, protocols and specifications that help DL to interoperate with one another were widely discussed and deployed.

Originality/value

This paper expatiates on the background, development and future trend of the CADL project for the first time in the literature. It is concluded that researchers and the public from China as well as other countries thus may benefit from both positive and improvable DL construction experiences.

Abstract

Purpose

The purpose of this paper is to provide an insight into the determinants of the customers’ attitude and behavioural intention to use Internet banking services, paying special attention to the role of perceived risk, trust, enjoyment, website design and social influence.

Design/methodology/approach

A research model grounded on the technology acceptance model (TAM) reflecting the effects of trust, perceived risk, perceived enjoyment, perceived website design and social influence on TAM constructs is proposed. The structural equation modelling technique is used to analyse a sample of 697 individual Internet banking users in India through an online survey.

Findings

The results of data analysis confirm some of the hypotheses drawn from the literature. Consistent with some of the other studies, perceived usefulness, perceived ease of use, trust and perceived enjoyment are found to be immediate direct determinants of customers’ attitude towards using Internet banking. Attitude, perceived risk, perceived enjoyment and trust determine the customers’ behavioural intentions to use Internet banking. Although the direct effect of perceived website design is significant only on perceived ease of use, its indirect effects are significant on perceived usefulness, attitude and behavioural intentions. Furthermore, perceived enjoyment exerts both direct and indirect effects on perceived usefulness but exerts only direct effect on perceived ease of use.

Research limitations/implications

Generalizability of the research is a practical limitation in consumer research studies and the present study is not an exception to that. The current study focused only on some technological, behavioural and attitudinal factors, and many customer-specific factors and other psychographic and behavioural factors such as cost, perceived value, service quality and satisfaction, which can provide more significant insight into the adoption process, are not a part of the scope of the study.

Practical implications

This research specifies the implications in three perspectives, viz., theoretical, methodological and managerial. Furthermore, this study provides the practical recommendations to enhance customer trust and guidelines to reduce perceived risk. The most significant implication for the banking sector is that apart from offering useful and user-friendly services, they need to build a trusting relationship with customers.

Originality/value

This study extends existing body of Internet banking literature by incorporating trust and risk perceptions. The effects of website design and perceived enjoyment on Internet banking acceptance have been examined and were found to be significant in the Indian context. In addition, it enables us to contribute to the current literature on the emerging Indian Internet banking services (IBS) market, which is largely under-researched.

Abstract

Purpose

This study proposes a multilevel framework to test the mechanisms and boundary conditions of the relationships between positive group affective tone (PGAT) and individual/team creativity.

Design/Methodology/Approach

Data are collected from 122 research and development (R&D) teams (including 305 members and 122 team leaders). Hierarchical linear modeling analyses and hierarchical regression analyses are performed to test hypotheses.

Findings

The results show that PGAT facilitates individual creativity via enhanced work engagement, and increases team creativity via team information exchange. Supporting the substituting perspective, we found that the positive indirect effects of PGAT on individual/team creativity were attenuated when supervisory support is high.

Research Limitations/Implications

Although all variables were collected at the same time and the individual-level variables were collected from the same source, our findings highlight the mechanisms explaining the beneficial effects of PGAT on individual/team creativity, and how supervisory support can substitute for such effects.

Practical Implications

In order to make the individuals and teams more creative, the organizations need to promote PGAT via the selection of appropriated leader and members or team social events. Moreover, supervisors support is particularly salient in enhancing team creativity when PGAT is low.

Originality/Value

This study is the one of the first study to test the motivational/social mechanisms linking the relationship between PGAT and individual/team creativity, and the competing theoretical perspectives regarding how supervisory support can moderate the PGAT–creativity linkage.

Abstract

Purpose

This study aims to investigate dynamic relations among office property price indices of 10 major cities in China for the years 2005–2021.

Design/methodology/approach

Using monthly data, the authors adopt vector error correction modeling and the directed acyclic graph for the characterization of contemporaneous causality among the 10 indices.

Findings

The PC algorithm identifies the causal pattern, and the linear non-Gaussian acyclic model algorithm further determines the causal path from which we perform innovation accounting analysis. Sophisticated price dynamics are found in price adjustment processes following price shocks, which are generally dominated by the top tier of cities.

Originality/value

This suggests that policies on office property prices, in the long run, might need to be planned with particular attention paid to the top tier of cities.

Abstract

Purpose

Criticality cognitions regarding the same workplace event often differ between leaders and employees. Nevertheless, its consequences on employee work outcomes remain unknown. In this study, we draw on cognitive dissonance theory to examine how and why leader–employee differences in cognitions of workplace event criticality impact employee job-related outcomes.

Design/methodology/approach

Wu used multilevel polynomial regression analyses from a time-lagged, multi-source field study with 145 leader–employee dyads to test our proposed model.

Findings

Leader–employee differences in cognitions of workplace event criticality can bring both benefits and perils to employees. Specifically, such differences can cause employee rumination, which in turn leads to an increase in both employee voice and fatigue.

Originality/value

This study contributes to the event and cognitive discrepancy literature in four ways. First, prior event studies largely adopted a singular employee perspective for investigation (e.g. Chen et al., 2021; Lin et al., 2021). By examining the impacts of event criticality from the dual perspective of leaders and employees, we attain a more comprehensive understanding of the implications of workplace events in organizational life. Second, extant studies have predominantly focused on the dark side of cognitive discrepancy (e.g. Bashshur et al., 2011; Erdogan et al., 2004; Grandey et al., 2013). Our study reveals that leader–employee differences in criticality cognitions can have both a bright and a dark side on employee outcomes, offering a more balanced and dialectical view of the consequences of cognitive discrepancy. Third, drawing on cognitive dissonance theory, we introduce employee rumination as an underlying mechanism to explain the impacts of leader–employee differences in criticality cognitions on employee voice and fatigue. Finally, while prior cognitive dissonance research has primarily employed an intrapersonal perspective (e.g. Sivanathan et al., 2008; Pugh et al., 2011; Grandey et al., 2013), our study adopts an interpersonal lens and underscores that interpersonal differences in cognitions can also serve as an example of cognitive discrepancy to instigate internal dissonance processes. By doing so, we enrich our understanding of cognitive dissonance theory.

Abstract

Purpose

Drawing on follower-centric leadership theory, the study examines the role of perceived homophily between the leader and the follower, follower's individual-level power distance orientation (PDO) and follower's perceived employability in moderating the effects of authoritarian and benevolent paternalistic leadership (BPL) on followers' turnover intentions.

Design/methodology/approach

The study analyzes a sample of 403 white-collar Russian employees.

Findings

Whereas both leadership styles generally decrease followers' turnover intentions, they operate differently. Authoritarian leadership (AL) is more effective among followers with higher follower-leader homophily and PDO, whereas BPL is effective only among followers with low perceived homophily and PDO, and more effective among followers with higher perceived employability.

Originality/value

The study extends research on non-participative styles of leadership, their effects and boundary conditions.

Abstract

Purpose

Nurses' turnover intention has become a major issue in developing countries with high power distance cultures. Therefore, the authors attempt to investigate how turnover intention among nurses' can be reduced through paternalistic leadership (PL). The authors further investigate the mediating role of job satisfaction between the associations of benevolent, moral and authoritarian dimensions of PL with turnover intention. Finally, the authors examined perceived organizational support (POS) as a conditional variable between job satisfaction and turnover intention.

Design/methodology/approach

The authors collected data from 374 nurses working in public and private hospitals of high power distance culture using a questionnaire-based survey on convenience basis.

Findings

Structural equation modeling confirms that benevolent and moral dimensions of PL positively affect nurses' job satisfaction which helps them reduce their turnover intention. While the authoritarian dimension of PL negatively affects job satisfaction to further enhance their turnover intention. In addition, the authors noted POS as a conditional variable to trigger the negative effect of job satisfaction on turnover intention.

Research limitations/implications

The authors used a cross-sectional design to collect responses and ensured the absence of common method variance through Harman's Single factor test.

Originality/value

This study identified the mechanism (job satisfaction and POS) through which benevolent, moral and authoritative dimensions of PL predict turnover intention among nurses working in high power distance culture.

研究目的

護士有離職意向,在擁有高權力距離文化的發展中國家,已成為一個重大的問題。因此,我們擬探討如何可以透過採用家長式領導、把護士離職的意欲減低,繼而研究工作滿足感,在離職意向與家長式領導中仁慈、道德和獨裁這三個層面的關係中所起的中介作用。最後,我們就組織支持感,作為是工作滿足感與離職意向之間的一個條件變數,進行了研究。

研究設計/方法/理念

本研究透過採用在便利的基礎上進行的問卷調查,從374名在高權力距離文化的公營和私營醫院內工作的護士取得數據,進行分析。

研究結果

結構方程模型證實了家長式領導中的仁慈和道德這兩個層面,會對可減低護士離職意欲的工作滿足感,產生積極的影響。家長式領導中的獨裁層面、則會對護士的工作滿足程度產生負面的影響,繼而增強其離職意欲。而且,我們確認了組織支持感是一個會增強工作滿足感與離職意向之間負相聯的條件變數。

研究的局限/啟示

我們以橫斷面的設計法來收集回應,並透過採用哈曼 (Harman) 的單因素檢定法,來確保共同方法變異不會存在。

研究的原創性/價值

本研究確定了一個 (工作滿足感與組織支持感) 機制,透過這機制,家長式領導中的仁慈、道德和獨裁這三個層面可預測於高權力距離文化工作的護士的離職意向。
