Abstract

Purpose

For ranking aggregation in crowdsourcing task, the key issue is how to select the optimal working group with a given number of workers to optimize the performance of their aggregation. Performance prediction for ranking aggregation can solve this issue effectively. However, the performance prediction effect for ranking aggregation varies greatly due to the different influencing factors selected. Although questions on why and how data fusion methods perform well have been thoroughly discussed in the past, there is a lack of insight about how to select influencing factors to predict the performance and how much can be improved of.

Design/methodology/approach

In this paper, performance prediction of multivariable linear regression based on the optimal influencing factors for ranking aggregation in crowdsourcing task is studied. An influencing factor optimization selection method based on stepwise regression (IFOS-SR) is proposed to screen the optimal influencing factors. A working group selection model based on the optimal influencing factors is built to select the optimal working group with a given number of workers.

Findings

The proposed approach can identify the optimal influencing factors of ranking aggregation, predict the aggregation performance more accurately than the state-of-the-art methods and select the optimal working group with a given number of workers.

Originality/value

To find out under which condition data fusion method may lead to performance improvement for ranking aggregation in crowdsourcing task, the optimal influencing factors are identified by the IFOS-SR method. This paper presents an analysis of the behavior of the linear combination method and the CombSUM method based on the optimal influencing factors, and optimizes the task assignment with a given number of workers by the optimal working group selection method.

Abstract

Purpose

Develop a comprehensive framework for assessing the knowledge organization systems (KOSs), including the taxonomy of Wikipedia and the ontologies of Wikidata, with a specific focus on enhancing management and retrieval with a gender nonbinary perspective.

Design/methodology/approach

This study employs heuristic and inspection methods to assess Wikipedia’s KOS, ensuring compliance with international standards. It evaluates the efficiency of retrieving non-masculine gender-related articles using the Catalan Wikipedian category scheme, identifying limitations. Additionally, a novel assessment of Wikidata ontologies examines their structure and coverage of gender-related properties, comparing them to Wikipedia’s taxonomy for advantages and enhancements.

Findings

This study evaluates Wikipedia’s taxonomy and Wikidata’s ontologies, establishing evaluation criteria for gender-based categorization and exploring their structural effectiveness. The evaluation process suggests that Wikidata ontologies may offer a viable solution to address Wikipedia’s categorization challenges.

Originality/value

The assessment of Wikipedia categories (taxonomy) based on KOS standards leads to the conclusion that there is ample room for improvement, not only in matters concerning gender identity but also in the overall KOS to enhance search and retrieval for users. These findings bear relevance for the design of tools to support information retrieval on knowledge-rich websites, as they assist users in exploring topics and concepts.

Abstract

Purpose

New product development (NPD) projects are strategically important for firms’ operations but suffer from high failure rates. Leadership is a key factor for project success. However, in contrast to positive project leadership, project managers’ knowledge hiding has received little attention. Drawing on the input-mediator-output (IMO) framework and model of work team resilience, we explored the effect of project managers’ destructive knowledge hiding (i.e. evasive hiding and playing dumb) on project team performance (i.e. efficiency and effectiveness) and the serial indirect effect through team psychological safety and transactive memory systems.

Design/methodology/approach

We conducted a time-lagged multiple-sourcing investigation of Chinese high-tech firms and tested the hypotheses using data collected from 105 NPD project teams.

Findings

Our findings demonstrated that project managers’ knowledge hiding negatively affects NPD project team performance and indirectly negatively affects transactive memory systems through team psychological safety. Moreover, project managers’ knowledge hiding exerts a negative indirect effect on team performance through team psychological safety and transactive memory systems in serial.

Originality/value

This study contributes to the literature on operations management (OM) by broadening our understanding of the connection between project managers' destructive knowledge hiding and the failure of NPD projects. In providing such insight, it also offers practical guidance for overcoming team-level obstacles arising from project managers' knowledge hiding.

Abstract

Purpose

The study aims to explore the effectiveness of performance-oriented practices like high-performance work practices (HPWPs) in higher education (HE), given its explicit focus on performance these days.

Design/methodology/approach

The study uses hierarchical linear modeling using statistical package for social sciences (SPSS 22.0) to test the hypotheses. An intertwined framework of the ability–motivation–opportunity (AMO) model and the job demand-resources (JD-R) model was proposed. The study considered strategic hiring, recognition and participatory decision-making as ability, motivation and opportunity-enhancing practices respectively. Further, the study addressed the impact of institutional level moderators, like administrative workload (AWL) and support staff (SS).

Findings

The findings based on the responses of 385 faculties and 443 students from 36 Indian institutes, indicated that HPWPs enhanced the education performance (EP) of HE institutes. Further, results revealed that both AWL and SS had differential effects on the relationship between HPWPs and EP. Contrary to authors’ expectations, SS showed a negative effect of the relationship between HPWPs and EP.

Research limitations/implications

The increased AWL was debilitating the beneficial effects HPWPs. The negative interaction effect of SS sheds light on the hidden issues surrounding SS in HE institutes. Based on findings, the study offered important theoretical and practical implications.

Originality/value

To the best of authors’ knowledge, the impact of innovative human resource (HR) practices in academia remains relatively under-researched, and the current study is an attempt to fill this void.

Abstract

Purpose

China's Belt and Road Initiative (BRI) is the most ambitious investment strategy for infrastructural development belonging to the significant potential for stimulating regional economic growth in Asia, Europe and Africa. This study aims to investigate the impact of infrastructure on spurring inward foreign direct investment (FDI) within the purview of human capital, GDP per capita, foreign aid, trade, domestic investment, population and institutional quality in BRI countries.

Design/methodology/approach

In doing so, the authors analyze panel data from 2000 to 2019 within the framework of the system generalized method of movement (GMM) approach for 66 BRI countries from Europe, Asia, Africa and the Middle East.

Findings

The investigated results demonstrate that aggregate and disaggregate infrastructure indices, e.g. transport, telecommunications, financial and energy infrastructures, are the driving forces in attracting foreign direct investment (FDI) in the BRI countries. In addition, control variables (i.e. institutional quality, human capital, trade, domestic investment, foreign aid and GDP per capita) play an essential role in spurring FDI inflows.

Originality/value

The authors’ study uniquely investigates both the pre- (2000–2012) and post- (2013–2019) BRI scenarios using the aggregate and disaggregate infrastructural components from the perspectives of full and clustered sample regions, such as Asia, Europe, Africa and the Middle East. The study provides several policy implications.

Abstract

Purpose

This study examines the relationship of principals’ systems thinking (PST) to student outcomes of academic achievement and school violence. The investigation relies on the contingency theory, according to which effective leadership is contingent on the nature of the situational influences to which managers are exposed. Specifically, the study investigates the influence of school structure – bureaucratic vs organic – on the relationship between PST and student outcomes of academic achievement and school violence after accounting for students’ socioeconomic backgrounds and principals' demographics.

Design/methodology/approach

A three-source survey design with self-reported and non-self-reported data was used, with a sample of 423 participants from 71 elementary schools in Israel. The sample included senior management team members and teachers. The data were aggregated at the school level of analysis.

Findings

Hierarchical regression analyses showed that organic school structure moderates the relationship between PST and student academic achievement, and bureaucratic school structure moderates the relationship between PST and school violence beyond the impact of students’ socioeconomic backgrounds.

Originality/value

This study provides important evidence for the benefits of aligning PST with school structure for improving student outcomes beyond the impact of students’ socioeconomic backgrounds. In addition, the study suggests principal system thinking leadership to achieve effective student outcomes that circumvent the effects of inequality on disadvantaged student groups.

Abstract

Czechia's economic growth is substantially dependent on foreign trade. An independent monetary policy in a managed floating exchange rate regime gives a unique perspective on the effects of the exchange rate on foreign trade. This chapter evaluates the effects of exchange rate development on different sectors of Czechia's foreign trade. Using disaggregated data based on trading partner and product category, the period from 1999 to 2020 is analyzed. Czechia's 10 major trading partners are included in the estimation. The relationship between exchange rates and foreign trade is assessed through a Johansen cointegration approach and modified vector error correction model. The results of the Johansen cointegration test indicate that the majority of the aggregate bilateral trade balances are in a long-term relationship with Czechia's gross domestic product (GDP), foreign GDP and exchange rate movements. The J-curve is proved only in chemicals and related products traded with France, manufactured goods traded with Italy and Slovakia and mineral fuels and lubricants traded with the Netherlands.

Abstract

Purpose

The purpose of the present study is to investigate the extent to which female and male university students from low-income countries express different entrepreneurial intentions. Specifically, the study empirically tests whether the anticipated financial returns to entrepreneurship versus salaried employment, or the perceived barriers to entrepreneurship exert a stronger influence on the relationship between gender and entrepreneurial intentions.

Design/methodology/approach

To test the relationship of anticipated rewards versus barriers to entrepreneurship on gender and entrepreneurial intention, the study uses new data from a field survey in Sierra Leone and employs multiple mediation analyses.

Findings

The authors find that the relationship between gender and entrepreneurial intentions operates through the mediator of perceptions of the financial returns to entrepreneurship but not perceived barriers to entrepreneurship.

Research limitations/implications

The authors study intent, not behavior, acknowledging that cognitive intent is a powerful predictor of later behavior. Implications for future research on entrepreneurship in the African context are discussed.

Practical implications

The results from this study can be applied to both pedagogic and business settings in the field of entrepreneurship, with concrete implications for policymakers.

Originality/value

Results suggest that the gender gap in entrepreneurial intentions (EI) for science, technology, engineering and mathematics (STEM)- and business-educated students in Sierra Leone is predominantly influenced by anticipated financial returns to occupational choices, as opposed to perceived barriers to entrepreneurship, a more frequently studied antecedent to EI.

Abstract

Purpose

Trust plays a crucial role in overcoming uncertainty and reducing risks. Uncovering the trust mechanism in the sharing economy may enable sharing platforms to design more effective marketing strategies. However, existing studies have inconsistent conclusions on the trust mechanism in the sharing economy. Therefore, this study aims to investigate the antecedents and consequences of different dimensions of trust (trust in platform and trust in peers) in the sharing economy.

Design/methodology/approach

First, we conducted a meta-analysis of 57 related articles. We tested 13 antecedents of trust in platform (e.g. economic benefits, enjoyment, and information quality) and eight antecedents of trust in peers (e.g. offline service quality and providers’ reputation), as well as their consequences. Then, we conducted subgroup analyses to test the moderating effects of economic development level (Developed vs Developing), gender (Female-dominant vs Male-dominant), platform type (Accommodation vs Transportation), role type (Obtainers vs Providers), and uncertainty avoidance (Strong vs Weak).

Findings

The results confirm that all antecedents and consequences significantly affect trust in platform or peers to varying degrees. Moreover, trust in platform greatly enhances trust in peers. Besides, the results of the moderating effect analyses demonstrate the variability of antecedents and consequences of trust under different subgroups.

Originality/value

This paper provides a clear and holistic view of the trust mechanism in the sharing economy from an object-based trust perspective. The findings may offer insights into trust-building in the sharing economy.

Abstract

Purpose

Drawing on the transformational leadership theory, this study empirically tests the relationship between individual-focused transformational leadership (IFTL) (i.e. individualized consideration and intellectual stimulation) and change-oriented organizational citizenship behavior (Ch-OCB), proposing the mediating mechanism of job crafting. Also, this study examines the moderating role of employee resilience on the relationship between job crafting and Ch-OCB.

Design/methodology/approach

A nested data model using a 4-wave time-lagged sample of 210 employees–supervisors dyads from Indian information technology (IT) organizations was tested using hierarchical linear modeling.

Findings

The study results showed a significant association between IFTL and Ch-OCB. Furthermore, job crafting mediated the relationship between IFTL and Ch-OCB. Additionally, the findings indicate that the positive relationship between job crafting and Ch-OCB was found to be stronger when employee resilience levels were higher.

Practical implications

The study offers significant practical implications to managers, counselors and human resource management (HRM) practitioners for stimulating Ch-OCB. The study findings would aid HRM practitioners in designing individualized-oriented leadership programs to encourage employees to exhibit proactive job-crafting behavior, further augmenting Ch-OCB.

Originality/value

This paper adds to the existing transformational leadership literature by proposing new pathways through which IFTL stimulates job crafting, further leading to enhanced Ch-OCB. Mainly, research studies need to shed more light on leadership characteristics that influence employees' proactive and adaptive work behavior, i.e. job crafting and Ch-OCB. Essentially, this study examined the underlying mechanism through which IFTL relates to employees' Ch-OCB.
