Abstract
Purpose
The purpose of this paper is to investigate the role of consumers’ expectations and their antecedents on beliefs, attitude and behavioral intentions when they respond to new corporate social responsibility (CSR) information about a service firm.
Design/methodology/approach
Empirically, the authors measure prior beliefs, and then calibrate how those beliefs change in response to a piece of news. The authors develop a conceptual model articulating the nature and antecedents of three types of expectations: would, could and should. The authors use structural equation modeling to test how these expectations influence the consumer evaluation process.
Findings
The results show that the effect of could expectations on the evaluation process is felt via their influence on would expectations; that is, would expectations fully mediate the relationship between could expectations and attitude toward news. Similarly, attitude toward news fully mediates the relationship between would and should expectations and updated beliefs about the firm.
Research limitations/implications
In the selected service industry, the findings show that expectations are mediated by the new information that consumers receive when they are updating their prior beliefs. The authors demonstrate the ability to understand the antecedents of expectations, which provides a vehicle by which the organization can influence the consumer evaluation process.
Practical implications
In practice, managers can identify the antecedents of consumer expectations and thus influence the reference points against which those consumers will evaluate news about their product.
Social implications
CSR has important implications for multiple stakeholders and the authors calibrate the determinants of how news about the organization’s performance on it may affect consumer decision processes.
Originality/value
The paper introduces “could” expectations into the services literature, examines the antecedents of the different types of expectations, and studies how their effect is felt through the evaluation process.

Abstract
Purpose
The purpose of this paper is to investigate damaging processes in TaN thin film absorbers under action of high-voltage electrical pulse of nanosecond duration. Despite having mechanical origin of crack opening, estimation based on the readings from oscillograms shows uncharacteristically high velocities of the crack propagation.
Design/methodology/approach
Microscopic images of damaged absorbers showing the final result of the damaging process provided initial information about its geometrical peculiarities. Then, to clarify the dynamics of the process, the authors create the model of the crack, having elements of self-similarities and multiple stage opening. The influence of heating induced by current concentration at crack tip and of magnetic stress of this concentrated current are both included in the model.
Findings
Using physical parameters of TaN layers with flowing current and performing calculations the authors define the conditions required to initiate the damaging process and to sustain it. Danger of such damage is relevant for high-Tc superconducting thin films after their switching to normal state which is induced by the high-voltage pulse.
Practical implications
There were made recommendations to manufactures aiming to improve electrical durability of the absorbers in an effort to prevent the damaging influence of power nanosecond electrical pulses.
Originality/value
Three stage opening model implies the appearance of zone of high-energy dissipation that can lead to detonation-like destruction of the film and, therefore, explain the high velocities of crack propagation.

Abstract
Purpose
This paper aims to explore the motivation and job satisfaction of employees in the hospitality industry in Dubai, using Herzberg’s two-factor theory of motivation.
Design/methodology/approach
This qualitative research encompassed 20 interviews with employees at four different job levels from a 4-star hotel in Dubai, selected through purposive and quota sampling.
Findings
Findings show that achievement, recognition and responsibility are essential motivators. However, these were sources of dissatisfaction amongst employees from the lower job levels. Leader quality is crucial to hygiene. Moreover, it is a key motivator and a powerful source of job satisfaction.
Research limitations/implications
This cross-sectional study entailed a small sample size of 20 employees from one hotel in Dubai. Therefore, the only generalisation to theory is permitted and not to a broader population, such as hospitality workers from other hotels in Dubai or any of the other six United Arab Emirates.
Practical implications
The two specific human resource programmes and practices presented in this paper can exert a positive influence on employees’ motivation and job satisfaction. This, in turn, will bring the hotel in a strong position to compete for motivated and competent human capital to deliver high quality guest services to gain a competitive advantage in the hospitality industry in Dubai.
Originality/value
This paper contributes to the literature first, by identifying the type of motivation of the hotel’s employees as follows: “prosocial motivation”, evoked by satisfaction with motivators and hygienes. Second, by presenting a “Satisfier and Hygiene model for Prosocial Motivation and Job Satisfaction”, illustrating the reciprocal relation between prosocial motivation and job satisfaction.

Abstract
Outlines previous research on company failure prediction and discusses some of the methodological issues involved. Extends an earlier study (Tan 1997) using artificial neural networks (ANN) to predict financial distress in Australian credit unions by extending the forecast period of the models, presents the results and compares them with probit model results. Finds the ANN models generally at least as good as the probit, although both types improved their accuracy rates (for Type I and Type II errors) when early warning signals were included. Believes ANN “is a promising technique” although more research is required, and suggests some avenues for this.

Abstract
Purpose
A high-fidelity simulation platform helps to verify the feasibility of the controller and reduce the cost of subsequent experiments. Therefore, this paper aims to design a high-fidelity hardware-in-the-loop (HIL) simulation platform for the tail-sitter vehicles.
Design/methodology/approach
The component breakdown approach is used to develop a more reliable model. Thruster dynamics and ground contact force are also modeled. Accurate aerodynamic coefficients are obtained through wind tunnel tests. This simulation system adopts a mode transition method to achieve continuous simulation for all flight modes.
Findings
Simulation results are in good agreement with the flight log and successfully predict the state of the vehicle.
Originality/value
First, the effects of the propeller slipstream are considered. Second, most researchers ignore the parasitic drag caused by the landing gear and other appendages, which is discussed in this study. Third, a ground contact model is implemented to allow a realistic simulation of the takeoff and landing phases. Fourth, complete wind tunnel tests are conducted to obtain more accurate aerodynamic coefficients. Finally, a mode transition method is deployed in the HIL simulation system to achieve continuous simulation for all flight modes.

This paper aims to design a global controller that is operational throughout all flight modes and less dependent on an accurate model.
Abstract
Purpose
This paper aims to design a global controller that is operational throughout all flight modes and less dependent on an accurate model.
Design/methodology/approach
By adopting the interconnection and damping assignment passivity-based control (IDA-PBC) technology and compensating extra inputs for handling the unknown dynamics and time-varying disturbances, a model-free control (MFC)-based global controller is proposed.
Findings
Test results indicate that the designed controllers are more suitable for actual flight as they have smaller position tracking errors and energy consumption in all flight phases than the excellent model-free controller intelligent-PID.
Practical implications
The designed global controller, which works in all flight modes without adjusting its structure and parameters, can realize a stable and accurate tracking control of a tail-sitter and improve the resistance to unknown disturbances and model uncertainties.
Originality/value
The newly-designed controller is considered as an enhanced version of the traditional MFC. It further improves the control effect by using the poorly known dynamics of the system and choosing the IDA-PBC as the control auxiliary input. This method eliminates the unnecessary dynamics to continuously stabilize the vehicle with suitable energy consumption covering its entire flight envelope.

Abstract
Purpose
The authors examine whether Chinese banks use loan loss provisions (LLPs) for capital management, income smoothing and signaling purposes, and assess the effect of the recent regulatory changes following the implementation of Chinese Basel III on such behavior.
Design/methodology/approach
The authors use a unique set of hand-collected data on bank capital combined with financial data downloaded from the China Stock Market and Accounting Research (CSMAR) database. Multivariate regression models are used to test our hypotheses.
Findings
The authors find that while there is no evidence to suggest capital management practice before the Chinese Basel III, the implementation of the new regulations induced listed banks to manage tier-1 capital via LLPs. The authors also find strong support that Chinese banks engage in income smoothing via LLPs management, and there is no change in such tendency following the issuance of Chinese Basel III. Lastly, the authors do not find support for the signaling behavior by Chinese banks using LLPs.
Practical implications
The authors’ evidence suggests that elevated tier-1 capital and provisioning requirements may induce capital management by banks, which indicates a potential unintended effect brought forth by the new Basel regulations.
Originality/value
To the best of authors’ knowledge, this study is the first to examine Chinese banks' behavior relating to LLPs in terms of capital management, income smoothing and signaling. In particular, the authors use a sample containing a large number of Chinese commercial banks – previously a major data issue in other studies.

Abstract
Purpose
Installing a tight tolerant stepped shaft is not a trivial task for an industrial robot. If all peg-hole constraints are complete, the cascaded peg-in-hole task can be simplified into several independent stages and accomplished one by one. However, if some of the constraints are incomplete, the cross stage interference will bring additional difficulties. This paper aims to discuss the cascaded peg-in-hole problem with incomplete constraints.
Design/methodology/approach
In this paper, the problem is formulated according to geometric parameters of the stepped shaft and completeness of the corresponding hole. The possible jamming type is modeled and analyzed. A contact modeling and control strategy is proposed to compensate the peg postures under incomplete constraints.
Findings
The above methods are implemented on an experiment platform and the results verify the effectiveness of the proposed robotic assembly strategy.
Originality/value
Based on force/torque sensor, a hybrid control strategy for incomplete constraints cascaded peg-in-hole assembly problem is proposed.

Abstract
Purpose
The provision of meals has long been regarded as an essential part of treatment of hospitalized patients complementing medical procedures and nursing management. Today, despite changes in the health-care landscape, which focused on improving the quality and efficiency of hospital care, malnutrition among inpatient was still a common worldwide concern.
Design/methodology/approach
This was a multi-centre, randomized study conducted in 21 study sites comprising 21 state and specialist government hospitals under the Ministry of Health, Malaysia. The sample size for this study was calculated with purposive sampling method, followed by proportionate sampling to determine the random sample size of each of the study sites. The total sample size required for this study was 2,759 subjects. A validated data collection form was used in the study.
Findings
Only 32.2 % and 37.6 % of subjects achieved adequate energy and protein intake, respectively, during their admission to medical ward. The study result showed that the overall mean energy and protein intake was 794.6 ± 487.8 kcal and 35.2 ± 24.3 g, respectively. The estimated energy (p = 0.001) and protein (p = 0.001) intake of all study sites was significantly lower compared to the adequacy value.
Research limitations/implications
The adequacy intake in this study was only carried out in medical wards, thus reproducible result among other wards in different study sites could not be confirmed. Besides, this study assumed that the portion eaten by subjects during lunch and dinner was the same, and therefore, either one was recorded together with breakfast and either lunch or dinner to represent a subject’s daily intake.
Originality/value
This was the first nationwide study to report the adequacy of energy and protein intake of patients receiving therapeutic diets in the government hospital setting in Malaysia.
