Abstract

Purpose

To strengthen the correlation analysis on risk factors of drug production safety and reduce the influence due to fuzzy judgments, a safety risk assessment method based on Grey-Analytic Network Process (G-ANP) is proposed.

Design/methodology/approach

First, an index system evaluating drug production safety risk is constructed according to the “Good Manufacture Practice of Medical Products,” next the influence weight of each risk index is derived by using the Analytic Network Process, then the grey number of each risk index is determined by further utilizing the grey statistical theory, and finally the risk level of drug production is obtained.

Findings

An empirical study is conducted and the results support the feasibility and practicability to use G-ANP method for drug production safety risk evaluation. The results of the case show that it is feasible and practical to use G-ANP method for drug production safety risk evaluation.

Originality/value

The innovation lies in the use of G-ANP method to fully consider the interdependence and interaction between the risk factors of drug production safety, which improves the objectivity in judging the risk level of drug production and provides a scientific basis for pharmaceutical manufacturers to formulate further decisions and management in the case of insufficient quantification of risk factors. Based on the findings, more targeted suggestions are made to reduce the production risk of pharmaceutical enterprises.

Abstract

Purpose

The purpose of this paper is to examine the causal relationship between Chinese housing and stock markets. The authors discuss the three transmission mechanisms between the two markets: wealth effect, modern portfolio theory and credit-price effect. Moreover, the authors focus on the effects of inflation on the relationship between the two markets.

Design/methodology/approach

This paper uses wavelet analysis to test the housing and stock markets relationship both in the frequency domain and time domain.

Findings

The empirical results indicate that housing prices have a positive effect on stock prices, and these have the same effect on housing prices. Moreover, this positive effect means that stock prices have a wealth effect on housing prices and these have a credit-price effect on stock prices.

Research limitations/implications

These results provide information to financial institutions and individual investors in China to assist them in constructing investment portfolios within these two asset markets.

Originality/value

The authors first use wavelet analysis to analyze Chinese housing and stock markets and to provide information both on the frequency domain and time domain. Moreover, the authors take the inflation factor as a control variable in the causal relationship between the housing and stock markets.

Abstract

Purpose

In the digital workplace, enterprise social media (ESM) are widely used for work and social purposes, which may afford employees resources to build their career adaptability. However, limited theoretical evidence is about how to build career adaptability through different ESM uses (work-oriented ESM use and socialization-oriented ESM use). This study thus aims to enrich the theoretical understanding of the relationship between different ESM uses and career adaptability by examining the different mediating mechanisms of role clarity and psychological closeness and the moderating effect of mindfulness based on affordance theory.

Design/methodology/approach

SPSS PROCESS and AMOS were used to analyze the data collected from 209 full-time employees at three-time points.

Findings

Our results showed that work-oriented ESM use exerts a positive effect on employees’ career adaptability via role clarity, while socialization-oriented ESM use has a positive effect on employees’ career adaptability via psychological closeness. Mindfulness strengthens the positive effect of work-oriented ESM use on career adaptability via role clarity.

Practical implications

Managers need to notice that both work-oriented and socialization-oriented ESM use can benefit employees, but there are different effecting mechanisms of ESM use for work and social purposes, and organizations should keep cultivating the mindfulness of employees.

Originality/value

This study contributes to the ESM literature by investigating two different influencing mechanisms of ESM uses on employees’ career adaptability and the moderating effects of mindfulness.

Abstract

Purpose

This paper aims to develop an algorithm to study the impact of dynamic resource disruption on project makespan and provide a suitable resource disruption ratio for various complex industrial and emergency projects.

Design/methodology/approach

This paper addresses the RCPSP in dynamic environments, which assumes resources will be disrupted randomly, that is, the information about resource disruption is not known in advance. To this end, a reactive scheduling model is proposed for the case of random dynamic disruptions of resources. To solve the reactive scheduling model, a hybrid genetic algorithm with a variable neighborhood search is proposed.

Findings

The results obtained on the PSLIB instances prove the performance advantage of the algorithm; through sensitivity analysis, it can be obtained, the project makespan increases exponentially as the number of disruptions increase. Furthermore, if more than 50% of the project's resources are randomly disrupted, the project makespan will be significantly impacted.

Originality/value

The paper focuses on the impact of dynamic resource disruptions on project makespan. Few studies have considered stochastic, dynamic resource uncertainty. In addition, this research proposes a reasonable scheduling algorithm for the research problem, and the conclusions drawn from the research provide decision support for project managers.
