Abstract

Purpose

The purpose of this paper is to explore the curvilinear relationship between workplace ostracism (supervisor ostracism and co-worker ostracism) and knowledge hoarding by using the conservation of resources theory. In addition, the paper predicts one possible situational context (political skill) that may influence employees’ reaction to ostracism.

Design/methodology/approach

Using a two-wave research design, the authors collected data from 240 samples in a Chinese diversified company. Hierarchical regression models were used to test the hypotheses.

Findings

The authors found that the relationship between workplace ostracism (supervisor ostracism and co-worker ostracism) and knowledge hoarding was U-shaped. Moreover, political skill moderated the linkage between workplace ostracism and knowledge hoarding such that the U-shaped association was stronger for people higher, rather than lower, in political skill.

Originality/value

By exploring a curvilinear relationship between ostracism and knowledge hoarding, the study enriches the knowledge hoarding literature by adding a substantive predictor of knowledge hoarding. The findings can also extend the workplace ostracism literature by providing a new conceptual analysis of interpreting the inconsistent findings involving the influence of workplace ostracism. Moreover, identifying political skill as a moderator can gain a better understanding of when and why an ostracized employee’s knowledge hoarding behavior can be less likely.

Abstract

Purpose

The fuzziness and complexity of evaluation information are common phenomenon in practical decision-making problem, interval neutrosophic sets (INSs) is a power tool to deal with ambiguous information. Similarity measure plays an important role in judging the degree between ideal and each alternative in decision-making process, the purpose of this paper is to establish a multi-criteria decision-making method based on similarity measure under INSs.

Design/methodology/approach

Based on an extension of existing cosine similarity, this paper first introduces an improved cosine similarity measure between interval neutosophic numbers, which considers the degrees of the truth membership, the indeterminacy membership and the falsity membership of the evaluation values. And then a multi-criteria decision-making method is established based on the improved cosine similarity measure, in which the ordered weighted averaging (OWA) is adopted to aggregate the neutrosophic information related to each alternative. Finally, an example on supplier selection is given to illustrate the feasibility and practicality of the presented decision-making method.

Findings

In the whole process of research and practice, it was realized that the application field of the proposed similarity measure theory still should be expanded, and the development of interval number theory is one of further research direction.

Originality/value

The main contributions of this paper are as follows: this study presents an improved cosine similarity measure under INSs, in which the weights of the three independent components of an interval number are taken into account; OWA are adopted to aggregate the neutrosophic information related to each alternative; and a multi-criteria decision-making method using the proposed similarity is developed under INSs.

Abstract

Purpose

The application of the traditional failure mode and effects analysis (FMEA) technique has been widely questioned in evaluation information, risk factor weights and robustness of results. This paper develops a novel FMEA framework with extended MULTIMOORA method under interval-valued Pythagorean fuzzy environment to solve these problems.

Design/methodology/approach

This paper introduces innovatively interval-value Pythagorean fuzzy weighted averaging (IVPFWA) operator, Tchebycheff metric distance and interval-value Pythagorean fuzzy weighted geometric (IVPFWG) operator into the MULTIMOORA submethods to obtain the risk ranking order for emergencies. Finally, an illustrative case is provided to demonstrate the practicality and feasibility of the novel fuzzy FMEA framework.

Findings

The feasibility and validity of the proposed method are verified by comparing with the existing methods. The calculation results indicate that the proposed method is more consistent with the actual situation of project and has more reference value.

Practical implications

The research results can provide supporting information for risk management decisions and offer decision-making basis for formulation of the follow-up emergency control and disposal scheme, which has certain guiding significance for the practical popularization and application of risk management strategies in the infrastructure projects.

Originality/value

A novel approach using FMEA with extended MULTIMOORA method is developed under IVPF environment, which considers weights of risk factors and experts. The method proposed has significantly improved the integrity of information in expert evaluation and the robustness of results.

Abstract

Purpose

The purpose of this paper is to examine the curvilinear relationship between knowledge leadership and knowledge hiding and the moderating role of psychological ownership on influencing the curvilinear relationship.

Design/methodology/approach

In total, 403 data were collected from participants in a high-technology company via a two-wave survey. Hierarchical regression analyses were used to test the hypotheses.

Findings

Results revealed an inverted U-shaped relationship between knowledge leadership and knowledge hiding. The employees exhibited more knowledge hiding in a moderate level of knowledge leadership than in lower and higher levels of knowledge leadership. Moreover, psychological ownership significantly moderated the curvilinear relationship such that the inverted U-shaped relationship was more pronounced among employees with high psychological ownership.

Practical implications

Employees’ reaction to knowledge leadership may vary from different levels of knowledge leadership. Moreover, organizations should boost employees’ psychological ownership especially for the collective identity that helps them own knowledge as “ours.”

Originality/value

This study extends both the leadership and knowledge management behavior literatures.

Abstract

Purpose

This study aims to research the influence of non-probabilistic design variables on interval robust optimization of electric multiple units (EMU) brake module, therefore obtain the reasonable of design variables of the EMU brake module.

Design/methodology/approach

A robust optimization model of the EMU brake module based on interval analysis is established. This model also considers the dimension tolerance of design variables, and it uses symmetric tolerance to describe the uncertainty of design variables. The interval order relation and possibility degree of interval number are employed to deal with the uncertainty of objective function and constraint condition, respectively. On this basis, a multiobjective robust optimization model in view of interval analysis is established and applied to the robust optimization of the EMU brake module.

Findings

Compared with the traditional method and the method proposed in the reference, the maximum stress fluctuation of the EMU brake module structure is smaller after using the method proposed in this paper, which indicates that the robustness of the maximum stress of the structure has been improved. In addition, the weight and strength of the structure meet the design requirements. It shows that this method and model introduced in this research have certain feasibility.

Originality/value

This study is the first attempt to apply the robust optimization model based on interval analysis to the optimization of EMU structure and obtain the optimal solution set that meets the design requirements. Therefore, this study provides an idea for nonprobabilistic robust optimization of the EMU structure.

Abstract

Purpose

This study aims to examine the moderating effects of psychological entitlement and perceived organizational support (POS) on the relationship between work connectivity behavior after-hours (WCBA) and job satisfaction.

Design/methodology/approach

Data were collected from 217 full-time employees of an Internet company in China at two points in time separated by about one month. Hierarchical regression and simple slope analyses were conducted to test hypotheses.

Findings

The results showed that WCBA was negatively related to job satisfaction and that this relationship could be mitigated by POS. Moreover, psychological entitlement aggravated this relationship, and this aggravating effect was stronger when POS was at low levels.

Practical implications

Managers should avoid intervening employees' nonwork domains too much. If this is unavoidable, managers should provide adequate organizational support to help employees cope with the challenges brought by WCBA. Besides, managers need to pay close attention to highly entitled employees and take measures to modify their expectations.

Originality/value

First, this study enriches the understanding of what WCBA is and how WCBA works by investigating the influencing mechanism of WCBA from the perspectives of effort–reward imbalance and job demands–resources. Second, by verifying the moderating effects of psychological entitlement and POS, this study provides insights into the boundaries of the WCBA–job satisfaction relationship. Third, this study contributes to the literature on psychological entitlement by identifying its one applicable condition.

Abstract

Purpose

To achieve sustainability for a construction project requires the achievement of economic, environmental and social sustainability at the same time. The economic sustainability of a project should be built into the stipulated cost. The unbalanced bidding always contribute cost overrun for a construction project. The purpose of this paper is to develop a method for identifying unbalanced bidding.

Design/methodology/approach

The problem of identifying unbalanced bidding is a comprehensive evaluation problem. All line items and bidders in bills of quantities are evaluation factors and evaluation objects, respectively, and the engineer’s estimated prices are considered as the evaluation benchmarks. The weights of these factors are determined through integrating the entropy weight method and the analytic hierarchy model, which consider subjective and objective factors in the weighting process.

Findings

The proposed model can be used to quantitatively evaluate unbalanced bids. The identification process can be analyzed within a short period, specifically with the aid of Microsoft Excel, reducing delays in awarding contracts. The results show that the model will support owners as they efficiently and effectively identify unbalanced bids in the bid evaluation stage to mitigate the negative consequences of unbalanced bidding.

Practical implications

A case study is given to verify the feasibility and practicability of the proposed method, which not only assists owners in efficiently and effectively identifying unbalanced bidding, but also promotes the economic sustainability of construction projects.

Originality/value

The fuzzy comprehensive evaluation method is used to detect unbalanced bidding, allowing owners to be objective as they identify and reduce unbalanced bidding at the procurement stage.

Abstract

Purpose

In recent years, with the increasingly serious urban water environmental pollution, the government has exerted considerable effort to promote the comprehensive improvement of the water environment and conducted numerous urban water environment treatment public–private partnership (PPP) projects (UWETP-PPP). The sustainability assessment of UWETP-PPP has important theoretical and practical significance for the public and private sectors to systematically evaluate the sustainability of projects and promote the sustainable development of projects. Therefore, the purpose of this paper is to advance a method to evaluate the sustainability of UWETP-PPP.

Design/methodology/approach

The paper adopted fuzzy logic method to evaluate the sustainability of UWETP-PPP. First, this paper constructed the sustainability assessment indicator system of UWETP-PPP. Second, this paper determined the appropriate linguistic scale for assessing the performance ratings and importance weights of UWETP-PPP sustainability indicators and collected experts’ evaluations of the project through questionnaires. Then, the linguistic variables were approximated as fuzzy numbers through the concept of fuzzy theory. Finally, the sustainability of the project was determined and the weak sustainability aspects of the project were identified by calculation.

Findings

The feasibility of this method was verified by a specific case. And, the results of the case study showed that the UWETP-PPP in Xuchang City, China, was sustainable, and the indicators of weak sustainability of the project were identified, namely, internal return ratio (IRR), sustainable cash flow, provision of employment opportunities, energy efficiency, comprehensive use of water resources, use of innovation materials, renewal of project facilities, adoption of advanced engineering technology, use of construction waste and waste recycling and reuse. This paper also proposed corresponding suggestions for further improving the sustainability of the UWETP-PPP in Xuchang City, China.

Originality/value

This paper makes two contributions: first, the fuzzy logic method is applied to provide new ideas for a sustainability assessment of UWETP-PPP, and the assessment results facilitate ways to monitor and estimate the degree of sustainability. Second, the identified indicators of weak sustainability provide useful references for the public and private sectors regarding implementing appropriate measures to improve the sustainability level of UWETP-PPP.

Abstract

Purpose

During the early 1970s, faced with the serious demographic situation, China began to fully implement the policy of family planning in urban and rural regions. Nowadays, the problems of pension and medical care for aged parents confronted by the first generation of the one‐child family have begun to gradually appear. Meanwhile, China's population and the family planning are also faced with some problems that are difficult to solve, including unbalanced fertility rate of urban and rural population, the gender imbalance, the difficulty of the risk diversification in a one‐child family, as well as the profound contradiction between the stability of the family planning policy and the drive of administrative measures. Therefore, it is necessary to establish the integrated‐scheduled life security system of the one‐child family in urban and rural areas, in order to overcome the problems and to promote the transformation of the family planning policy. The purpose of this paper is to discuss the life security system for China's one‐child families.

Design/methodology/approach

The life security system for the one‐child family proposed by this paper consists of three issues: the basic security based on the level of social security, the additional security of the policy insurance and the supplementary security of the commercial insurance. The paper begins with the history of the family planning policy in the first section and then go through some relevant articles regarding complementary measures such as maternity insurance, rural endowment insurance that only focused on one aspect of issues associated with the family planning. In section three, four typical problems are listed for the purpose of following discussion of corresponding solutions which are full of deficiency in section four. In part five, the integrated planning of the life security system for Chinese one‐child family is elaborated with risk and fund management. In the last part, we conclude that the family planning policy maintains stable, whereas measures to be taken are adjusted along with changeable new problems.

Findings

The policy insurance plays an increasingly important role in dealing with the life security of older people in one‐child families. It may be better to promote the kind of insurance.

Originality/value

The paper comprehensively discusses the life security system for Chinese families in compliance with the family planning policy.
