Abstract

Purpose

Employee voice has emerged as a strong predictor of positive organizational outcomes. Grounding the theoretical model in resource-based theory; this study conceptualizes how high-performance work system (HPWS) can enhance organizational innovation of small and medium enterprises (SMEs) through voice behaviors. Specifically, the purpose of this paper is to empirically test if employee voice mediates the relationship between HPWS and organizational innovation.

Design/methodology/approach

This study used a quantitative strategy and cross-sectional survey method for the collection of data from SMEs operating in Pakistan. A list of SMEs was obtained from the federal government organization responsible for the development of SMEs in Pakistan. A self-administered structured questionnaire was distributed and 239 randomly selected SMEs responded to the survey.

Findings

Findings confirmed the conceptualized model and revealed that HPWS was significantly and positively related to employee voice and organizational innovation. Employee voice was found as a significant predictor of organizational innovation and mediating factor in the relationship between HPWS and organizational innovation.

Research limitations/implications

This study is limited in terms of variables included in the conceptual model and relatively small size of the sample that was derived from a single federal organization. More variables and SMEs can be included in future studies to get broader results and, potentially, better findings.

Practical implications

SME managers/owners can design HR function in such a way that employees will be encouraged to raise their voice and participate more in the organization. Scholars should study voice behaviors distinct from citizenship behaviors.

Originality/value

This study is the first of its kind to conceptualize the relationship between HPWS, employee voice, and organizational innovation in SMEs of Pakistan.

Abstract

Purpose

This study aims to examine the influence of voluntary disclosure on bank value in Pakistan, considering the moderating effect of corporate governance characteristics: ownership control, board independence and board size.

Design/methodology/approach

The study uses data from 20 listed Pakistani banks for the period 2011–2021. The estimation contains robust fixed effect and its assumptions, and a model of standard error with panel corrections.

Findings

The findings revealed a weak positive impact of voluntary disclosure on bank value. However, the increase in the number of independent directors strengthens the positive impact of voluntary disclosure on a bank’s value. Conversely, increasing the ownership concentration, and board size (other than independent directors) may strongly decrease the impact of voluntary disclosure on a bank’s value in Pakistan.

Research limitations/implications

The study’s limitations include its exclusive focus on the Pakistani banking industry. Future research should take into account newer contexts and data. The findings suggest that future research should investigate the topic in various contexts, including a comparison of Islamic and conventional banks.

Practical implications

The practical implications for Pakistani banks emphasize transparency, board composition and ownership structure. In terms of managerial implications, using independent directors, aligning ownership interests and addressing disclosure challenges are highlighted.

Originality/value

Focusing on independent directors, ownership concentration and board size, this study enhances knowledge of the impact of voluntary disclosure on bank value in Pakistan. It contributes to agency theory and the literature in this domain.

Abstract

Purpose

In this paper, the authors investigate whether an independent and gender-diverse compensation committee strengthens the relationship between top managers' pay and firm performance in Chinese companies. The authors also investigate whether the independent compensation committee composed of all male directors is effective in designing the optimal contract for executives.

Design/methodology/approach

The authors use data from A-share listed companies on the Shenzhen and Shanghai stock exchanges from 2005 to 2015. As a baseline methodology, the authors use pooled ordinary least square (OLS) regression to draw inferences. In addition, cluster OLS regression, two-stage least square regression, the two-stage Heckman test and the propensity score matching method are also used to control for endogeneity issues.

Findings

The authors find evidence that an independent or gender-diverse compensation committee strengthens the link between top managers' pay and firm performance; that the presence of a woman on the compensation committee enhances the positive influence of committee independence on this relationship; that a compensation committee's independence or gender diversity is more effective in designing top managers' compensation in legal-person-controlled firms than they are in state-controlled firms; that gender diversity on the compensation committee is negatively associated with top managers' total pay; and that an independent compensation committee pays top managers more.

Practical implications

The study results highlight the role of an independent compensation committee in designing optimal contracts for top managers. The authors provide empirical evidence that a woman on the compensation committee strengthens its objectivity in determining top managers' compensation. The study finding supports regulatory bodies' recommendations regarding independent and women directors.

Social implications

The study findings contribute to the recent debate about gender equality around the globe. Given the discrimination against women, many regulatory bodies mandate a quota for women on corporate boards. The study findings support the regulatory bodies' recommendations by highlighting the economic benefit of having women in top management positions.

Originality/value

This study contributes to literature by investigating the largely overlooked questions of whether having a gender-diverse or independent compensation committee strengthens the relationship between top managers' pay and firm performance; whether an independent compensation committee is more efficient in setting executives' pay when it is gender-diverse; and whether the effect of independent directors and female directors on top managers' compensation varies based on the firm's ownership structure. Overall, the main contribution of the study is that the authors provide robust empirical evidence in support of the managerial power axiom.

Abstract

Purpose

This study aims to investigate whether the presence of female directors on audit committees affects audit fees in Chinese listed companies. This study also investigates whether the audit committee’s gender diversity moderates the relationship between the firm’s inherent situational factors (e.g. audit complexity and firm risk) and audit fees. Finally, this study investigates whether the effect of the audit committee’s gender diversity on audit fees varies with within-country institutional contingencies (e.g. state-owned enterprises [SOEs] vs non-SOEs and firms that are located in more developed regions vs firms that are located in less developed regions)

Design/methodology/approach

This study used the data of all A-share listed companies on the Shanghai and Shenzhen stock exchanges for the period from 2009 to 2015. The authors use ordinary least squares regression as a baseline methodology, along with firm fixed effect, Deference in Deference method, two-stage least squares regression, two-stage Heckman model and generalized method of moments models to control for the possible issue of endogeneity.

Findings

The study’s findings suggest that the presence of female directors on the audit committee improves internal monitoring and communication, which reduce the perceived audit risk and the need for assurances from external auditors. The results also suggest that female directors demand high-quality audits and further assurance from external auditors when the firm is more complex and riskier. In addition, the results suggest that within-country, institutional factors play significant role in shaping the governance role of gender-diverse audit committee.

Practical implications

The study contributes to the agency theory by providing evidence that the interaction between agency theory and corporate governance “board composition” generates an effective monitoring mechanism and contributing to the institutional theory by finding that role of female directors on audit committee varies from context to another. In addition, this study contributes to literature review of gender diversity in the boardroom by finding the economic benefit of having female directors on audit committee. Finally, this study has implications for policy-makers in promoting regulations to legalize women presence on the board, to external auditors in assessing control risk during planning the audit, to those who responsible for appointing audit committee members.

Originality/value

The authors extend earlier studies by providing novel evidence on the relationship between gender-diverse audit committees and audit fees in terms of both the supply- and demand-side perspectives; that female directors moderate the relationship between firm inherent situational factors (e.g. audit complexity and firm risk) and audit fees; and that the effect of audit committees’ gender diversity on audit fees varies with sub-national institutional contingencies.

Abstract

Purpose

This paper aims to examine whether CEO succession with gender change (male to female) affects audit fees in the Chinese setting. In addition, this study examines whether the relationship exists in both types of ownership, i.e. non-state-owned enterprises (SOEs) and SOEs.

Design/methodology/approach

This study uses data from all A-share non-financial firms listed on both the Shanghai Stock Exchange (SSE) and Shenzhen Stock Exchange (SZSE) for the period 2009 to 2015. To draw inferences, this study uses pooled ordinary least squares regression as a baseline technique. This study performs sub-sample analyzes for robustness. To account for endogeneity, this study uses three techniques including firm fixed-effects regression, the two-step Heckman model and the system generalized method of moments (GMM).

Findings

This study documents a significantly negative relationship between CEO succession with gender change and audit fees. However, the negative effect of CEO succession on audit fees is more pronounced in non-SOEs than SOEs. This study also finds, in additional analyzes, a strong negative effect of female CEO succession on audit fees in sub-sample of large, high-risk, high-performance and firms audited by non-big auditors. The main finding is robust across three endogeneity techniques.

Practical implications

The findings add to the ongoing debate about the underrepresentation of women in key executive positions such as CEO. The results suggest that CEO succession from male to female has a favorable effect on the quality of internal monitoring mechanisms (due to the superior monitoring skills of women) and enhances the quality of financial reporting. The study has practical implications for regulatory bodies and corporate decision-makers; this study encourages them to look into considering women in the executive succession framework.

Originality/value

This study contributes to the literature by exploring the effect of CEO succession with gender change (male to female) on audit fees in the context of China and the existence of this relationship in non-SOEs and SOEs.

Abstract

Purpose

This study aims to investigate the question concerning whether tournament incentives motivate chief executive officers (CEOs) to be socially responsible.

Design/methodology/approach

Data from all A-share Chinese companies listed on the Shanghai and Shenzhen stock exchanges for the period from 2010 to 2015 are used. To draw inferences from the data, ordinary least squares (OLS) regression and cluster OLS are used as a baseline methodology. To control for the possible issue of endogeneity, firm-fixed-effects regression, two-stage least squares regression and propensity score matching are used.

Findings

A reliable evidence is found that tournament incentives motivate CEOs to be more socially responsible. Additional analysis reveals that the positive effect of CEO tournament incentives on corporate social responsibility performance (CSRP) is more pronounced in state-owned firms than it is in non-state-owned firms. The study’s findings are consistent with tournament theory and the conventional wisdom hypothesis, which proposes that better incentives lead to competitiveness, which improves financial and social performance.

Practical implications

The study’s findings have implications for companies and regulators who wish to enhance CSRP by giving tournament incentives to top managers. Investment in social responsibility may reduce the conflict between executives and employees and improve the corporate culture.

Originality/value

This study contributes to the existing literature by providing the first evidence that CEOs’ tournament incentives play a vital role in CSRP. The study’s findings contribute to tournament theory.

Abstract

Purpose

The purpose of this paper is to evaluate the prevalence and antibiograms of bacteria isolated from various fresh fruit juices at a local market in Faisalabad.

Design/methodology/approach

Fresh fruit juice samples (n=125) were randomly collected using aseptic technique. Each sample (10 mL) was serially diluted with 90 mL of sterile peptone water, from 1×10−1 to 1×10−5. Each dilution was then used to inoculate nutrient agar by surface spread plating. Aerobic colony counts (ACCs) were determined by colony counting. The isolates were sub-cultured on blood and MacConkey agar. Preliminary identification was achieved on the basis of colony morphology and culture characteristic, and confirmed by API® 20E, 20NE, and API® Staph testing. Antimicrobial susceptibility testing was carried out using the Kirby-Bauer disk diffusion assay, per CLSI 2015 guidelines.

Findings

The mean ACC ranged from 2.0×106 CFU/mL to 4.93×106 CFU/mL, with the highest ACC determined for orange juice. Overall, 153 polymicrobial were identified in 125 samples; 103 of these were Gram-negative rods (GNR) and 28 were Gram-positive cocci (GPC). Escherichia coli (n=38), Klebsiella pneumoniae (n=32) and Pseudomonas aeruginosa (n=24) were the predominant GNR; Staphylococcus aureus (n=28) was the predominant GPC. Antibiogram analysis revealed that all GNR were resistant to ampicillin. However, most E. coli isolates were resistant to ceftazidime (72.4 percent of isolates), and ceftriaxone and cefepime (68.9 percent), while most K. pneumoniae isolates were resistant to cefepime (72 percent) and ceftriaxone (64 percent). All S. aureus isolates were resistant to penicillin, while most (64 percent) were resistant to piperacillin; the most effective drugs against bacteria were vancomycin and imipenem.

Practical implications

The findings suggest that the local government regulatory food and public health authorities should take immediate emergency measures. Appropriate surveillance studies and periodic monitoring of food items should be regularly performed to safeguard public health.

Originality/value

The current study revealed the prevalence of multidrug-resistant bacteria in freshly prepared fruit juices sold by local street vendors.

Abstract

Purpose

This study aims to investigate the research productivity of library and information science (LIS) authors affiliated with the 22 countries of the Arab League. It also identifies the top countries, organizations, authors, journals, natures of collaboration, and frequently used keywords in LIS research in the Arab world.

Design/methodology/approach

Bibliometric methods were used to evaluate the research performance of the authors affiliated with library organizations in the Arab region. The Elsevier Scopus database was selected for data retrieval. A comprehensive search strategy was adopted to retrieve 863 publications contributed by LIS authors affiliated with the Arab countries. VOS viewer, Biblioshiny, BiblioAnalyitics, Microsoft Access and Microsoft Excel were used for data visualization and analysis.

Findings

This paper presents the dynamics and the state of the LIS research in the Arab region published between 1951 and 2021. The results of the study have highlighted an upward trend in the growth of the publications, especially in the past four years. The largest number of studies were published in the year 2020. The country-wise analysis ranked Kuwait and Saudi Arabia as the top LIS research producing countries with five and four researchers, respectively. The Kuwait University, the King Fahd University of Petroleum and Minerals and the Imam Abdulrahman Bin Faisal University were the three most productive organizations. Academic libraries, social media, bibliometrics, information-seeking behavior, information literacy and knowledge management were identified as the major areas of interest for the researchers. Internet and open access were topics that had gained recent popularity, while the digital library, research data management, green librarianship, link data, cloud computing, library leadership, library automation and artificial intelligence were identified as areas requiring further attention. Furthermore, the single-author pattern was found to be the most preferred pattern.

Practical implications

The findings of this study would help prospective researchers in choosing the neglected areas of research that require further investigation. They would also help policymakers in identifying factors that need more attention and allocation of research funds.

Originality/value

To the best of the authors’ knowledge, this is the first comprehensive bibliometric study that presents a holistic picture of the LIS research in the Arab region.

Abstract

Purpose

Multilevel inverter (MLI) is an established design approach for inverter applications in medium-voltage and high-voltage range of applications. An asymmetric design synthesizes multiple DC input voltage sources of unequal magnitudes to generate a high-quality staircase sinewave comprising a large number of steps or levels. However, the implications of using sources of unequal magnitudes results in the requirements of a large variety of inverter switches and higher magnitudes of the total blocking voltage (TBV) rating of the inverter, which increase the cost. The purpose of this study is to present a solution based on algorithms for establishing DC source magnitudes and other design parameters.

Design/methodology/approach

The approach used in this study is to develop algorithms that bring an asymmetric cascaded MLI (ACMLI) design close to symmetric design. This approach then reduces the variety of switch ratings and minimizes the TBV of the inverter. Thus, the benefits of both asymmetric design (generation of a large number of voltage levels in the output waveform) and symmetric design (modularity) are achieved. The proposed algorithms can be applied to a number of ACMLI topologies, including classical cascaded H-bridge (CHB). The effectiveness of the proposed algorithms is validated by simulation in Matlab-Simulink and experimental setup.

Findings

Two new algorithms are proposed that reduce the number of variety of switches to just three. The variety can further be reduced to two under a specified condition. The algorithms are compared with the existing ones, and the results are promising in minimizing the TBV rating of the inverter, which results in cost reduction as well. For a specific case of four CHBs, the proposed Algorithm-1 produced 27% and Algorithm-2 produced 53% higher levels. Moreover, the presented algorithms produced minimum values of the TBV and resulted in minimum cost of inverter.

Originality/value

The proposed algorithms are novel in structure and have achieved the targeted values of minimized switch variety and reduced TBV ratings. Due to less variety, the inverter achieves a near symmetric design, which enables to attain the added advantages of modularity and reduced difference of power sharing among the DC sources.

Abstract

Purpose

Nowadays, it is hard to retain a knowledge monopoly since tacit knowledge has become essential for innovation and organizational effectiveness (ORP). This study analyzed the role of product innovation as a mediator in the relationship between the tacit knowledge management process (TKMP) and organizational performance. In addition, two moderating variables were examined: (1) Affective trust (AFT) between the tacit knowledge management process and product innovation relationship and (2) Task efficiency in product innovation and organizational performance (ORP) relationship.

Design/methodology/approach

Around 344 questionnaires were collected from various Chinese regions between February and April 2023 to conduct this study. The regression, mediation and moderation analyses on lower and higher-order data were evaluated using the SmartPLS approach.

Findings

The results validate that product innovation mediates the connection between managing tacit knowledge and the organization’s performance. Affective trust also plays a positive moderating role between tacit knowledge and product innovation. These results provide valuable theoretical and practical insights, substantiating various direct, indirect, mediate, and moderated effects hypotheses.

Research limitations/implications

The scope of the study was restricted to manufacturing companies; however, further research may broaden the model’s scope to include other industries. Furthermore, future research should continue to explore the role of task efficiency in the innovation process and identify strategies for enhancing task efficiency in organizations.

Practical implications

The study establishes the significance of effectively managing tacit knowledge for fostering product innovation. Company managers and leaders can promote employee trust, enhancing innovation capabilities and overall organizational effectiveness.

Originality/value

This study, involving dual moderation, explores the connections between processes of managing tacit knowledge, product innovation and organizational performance. It addresses research gaps, enriching the understanding of managing tacit knowledge, leading to organizational innovation and performance improvements. The study also highlights how affective trust is vital in strengthening the connection between TKMP and product innovation.
