Abstract
Purpose
Abundant studies of outpatient visits apply traditional recurrent neural network (RNN) approaches; more recent methods, such as the deep long short-term memory (DLSTM) model, have yet to be implemented in efforts to forecast key hospital data. Therefore, the current study aims to reports on an application of the DLSTM model to forecast multiple streams of healthcare data.
Design/methodology/approach
As the most advanced machine learning (ML) method, static and dynamic DLSTM models aim to forecast time-series data, such as daily patient visits. With a comparative analysis conducted in a high-level, urban Chinese hospital, this study tests the proposed DLSTM model against several widely used time-series analyses as reference models.
Findings
The empirical results show that the static DLSTM approach outperforms seasonal autoregressive integrated moving averages (SARIMA), single and multiple RNN, deep gated recurrent units (DGRU), traditional long short-term memory (LSTM) and dynamic DLSTM, with smaller mean absolute, root mean square, mean absolute percentage and root mean square percentage errors (RMSPE). In particular, static DLSTM outperforms all other models for predicting daily patient visits, the number of daily medical examinations and prescriptions.
Practical implications
With these results, hospitals can achieve more precise predictions of outpatient visits, medical examinations and prescriptions, which can inform hospitals' construction plans and increase the efficiency with which the hospitals manage relevant information.
Originality/value
To address a persistent gap in smart hospital and ML literature, this study offers evidence of the best forecasting models with a comparative analysis. The study extends predictive methods for forecasting patient visits, medical examinations and prescriptions and advances insights into smart hospitals by testing a state-of-the-art, deep learning neural network method.

Abstract
Purpose
Drawing on engagement theory, this study aims to examine how leader–member relationships, including on-work relationship (leader–member exchange [LMX]) and off-work relationship (leader–member guanxi [LMG]), influence employees’ promotive and prohibitive voice. Furthermore, the study uses procedural justice as the moderator to distinguish the effects of LMG and LMX on employees’ psychological states and voice through a mediated moderation model.
Design/methodology/approach
The authors use a sample from a private and local company in Southern China to test their theoretical model.
Findings
The study finds that both LMG and LMX have positive effects on employees’ voice behavior through employees’ psychological states (psychological meaningfulness and psychological safety).
Research limitations/implications
In a Chinese context, leaders have a more direct and powerful influence on employees than their counterparts in the Western society. Thus, the findings of LMX and LMG may not be generalizable to a Western context. A possible extension is to examine and compare the effects of social context (e.g., off-work leader–member relationship) on voice between the East and the West.
Practical implications
One important implication is that off-work relationship should be used by managers to encourage employee voice.
Originality/value
This study enriches the antecedents of voice with a new dimension of leader–member relationship, namely, LMG.

Abstract
Purpose
This paper aims to describe a numerical simulation method of ice accretion on BO105 helicopter blades for predicting the effects of trailing edge flap deflection on ice accretion.
Design/methodology/approach
A numerical simulation method of ice accretion is established based on Myers model. Next, the shape and location of ice accretion of NACA0012 airfoil are calculated, and a comparison between calculated results and experimental data is made to validate the method. This method is used to investigate the effect of trailing edge flap deflection on ice accretion of a rotor blade.
Findings
The numerical method is feasible and effective to study the ice accretion on helicopter rotor blades. The downward deflection of the trailing edge flap affects the shape of the ice.
Practical implications
This method can be further used to predict the ice accretion in actual flights of the helicopters with multielement airfoils.
Originality/value
The numerical simulation method here can lay a foundation of the research about helicopter flight performance in icing condition through predicting the shape and location of ice accretion on rotor blades.

Abstract
Purpose
The purpose of this paper is to fill important gaps by using the attachment theory and examining the effects of supervisors’ early family environment on their behaviors toward subordinates and subordinates’ responses.
Design/methodology/approach
The authors used samples of 334 supervisor–subordinate pairs from a manufacturing company.
Findings
The study finds that supervisors’ harmonious family environment has a positive influence on subordinates’ responses (job satisfaction, work-to-family enrichment and task performance) through the effect of supervisors’ positive working model and caregiving behavior. On the contrast, supervisors’ conflicting family environment has a negative influence on subordinates’ responses through the effect of supervisors’ negative working model and aggressive behavior.
Originality/value
Existing studies mainly explore the influence of organizational environment on supervisors’ treatment of their subordinates. However, few have examined the relationship between supervisors’ early family environment and their treatment of their subordinates.

Abstract
Purpose
This paper aims to solve the problems molybdenum disulfide (MoS2) nanosheets suffer from inadequate dispersion stability and form a weak lubricating film on the friction surface, which severely limits their application as lubricant additives.
Design/methodology/approach
MoS2/C60 nanocomposites were prepared by synthesizing molybdenum disulfide (MoS2) nanosheets on the surface of hydrochloric acid-activated fullerenes (C60) by in situ hydrothermal method. The composition, structure and morphology of MoS2/C60 nanocomposites were characterized. Through the high-frequency reciprocating tribology test, its potential as a lubricant additive was evaluated.
Findings
MoS2/C60 nanocomposites that were prepared showed good dispersion in dioctyl sebacate (DOS). When 0.5 Wt.% MoS2/C60 was added, the friction reduction performance and wear resistance improved by 54.5% and 62.7%, respectively.
Originality/value
MoS2/C60 composite nanoparticles were prepared by in-situ formation of MoS2 nanosheets on the surface of C60 activated by HCl through hydrothermal method and were used as potential lubricating oil additives.
