Abstract
Looks at consumer research in Greater China including Mainland China, Hong Kong and Taiwan. Maps out the contributions within this area and guides future research. Examines the state of the art over the 1979‐97 period, with particular emphasis on the topics that have been researched, the extent of the theory development in the field and the methodologies used in conducting research. Uses content analysis to review 75 relevant articles. Suggests that, while a considerable breadth of topics have been researched, there remains much to be done, there is further room for theoretical development in Chinese consumer behaviour studies; and the methodologies used need improvement and further refinement.

Abstract
One reason for the slow adoption rate of Electronic Fund Transfer at Point‐of‐Sale (EFTPoS) is that consumers perceive that EFTPoS has a higher level of risk than other traditional payment methods. Makes use of a concept in consumer behaviour and perceived risk to study the differences of consumers′ risk perceptions among alternative payment methods and whether these perceptions will be affected by the size of purchase and EFTPoS usage experience. The major findings are: (1) EFTPoS has the lowest physical risk and highest financial risk, the credit card has the lowest psychological risk and highest time loss risk, while cash has the highest physical risk and lowest performance risk; (2) Physical risk, financial risk and time loss risk for cash payment are significantly higher when the purchase is large, while performance risk for EFTPoS and credit card payment is significantly higher when the purchase is small; and (3) users of EFTPoS have a significantly higher level of perceived financial and time loss risk than non‐users, while non‐users have higher level of psychological risk. The overall finding is that the risk profile of EFTPoS is similar to that of the credit card but significantly different from cash.

This paper is focused on determining the asymmetric effects of exchange rate on money demand function in Nigeria.
Abstract
Purpose
This paper is focused on determining the asymmetric effects of exchange rate on money demand function in Nigeria.
Design/methodology/approach
It employs the empirical model of Baumol–Tobin. Baumol (1952), which was founded on the opportunity and transaction cost of holding money. Monetary aggregates, M1, M2 and M3, are used for the real money balances based on the nonlinear Autoregressive Distributed Lag bound testing procedure.
Findings
The results indicate that the positive and negative partial sum of exchange rate changes differ in magnitude and size, supporting the hypothesis of asymmetric effects of exchange rate changes on the demand for money in Nigeria.
Originality/value
This is the first paper to consider the new broad money aggregate (M3).

Abstract
Purpose
This paper aims to investigate the profile of the wind speed of a Cameroonian city for the very first time, as there is a growing trend for new wind energy installations in the West region of Cameroon. Two well-known artificial neural networks, namely, multi-layer perceptron (MLP) and nonlinear autoregressive network with exogenous inputs (NARX), were used to model the wind speed profile of the city of Bapouh in the West-region of Cameroon.
Design/methodology/approach
In this work, the profile of the wind speed of a Cameroonian city was investigated for the very first time since there is a growing trend for new wind energy installations in the West region of Cameroon. Two well-known artificial neural networks namely multi-layer perceptron (MLP) and nonlinear autoregressive network with exogenous inputs (NARX) were used to model the wind speed profile of the city of Bapouh in the West-region of Cameroon. The meteorological data were collected every 10 min, at a height of 50 m from the NASA website over a period of two months from December 1, 2016 to January 31, 2017. The performance of the model was evaluated using some well-known statistical tools, such as root mean square error (RMSE), mean absolute error (MAE) and mean absolute percentage error (MAPE). The input variables of the model were the mean wind speed, wind direction, maximum pressure, maximum temperature, time and relative humidity. The maximum wind speed was used as the output of the network. For optimal prediction, the influence of meteorological variables was investigated. The hyperbolic tangent sigmoid (Tansig) and linear (Purelin) were used as activation functions, and it was shown that the combination of wind direction, maximum pressure, maximum relative humidity and time as input variables is the best combination.
Findings
Maximum pressure, maximum relative humidity and time as input variables is the best combination. The correlation between MLP and NARX was computed. It was found that the MLP has the highest correlation when compared to NARX.
Originality/value
Two well-known artificial neural networks namely multi-layer perceptron (MLP) and nonlinear autoregressive network with exogenous inputs (NARX) were used to model the wind speed profile.

This study reinvestigates the validity of the Phillips curve in Nigeria for the period 1980–2020 by considering the asymmetric nexus between unemployment and inflation.
Abstract
Purpose
This study reinvestigates the validity of the Phillips curve in Nigeria for the period 1980–2020 by considering the asymmetric nexus between unemployment and inflation.
Design/methodology/approach
The nonlinear autoregressive distributed lag (NARDL) technique was used to decompose the unemployment variable into two components: tight and loosened labour markets.
Findings
The empirical outcome shows that unemployment has a significant negative effect on inflation when the labour market is tight and a weakly negative and significant effect on inflation when the labour market is loose. The study confirms an asymmetric Phillips curve in Nigeria since the positive (tight) unemployment rate exerts a greater effect on inflation than the negative (loosened) unemployment rate.
Practical implications
The findings of this study have important implications for implementing monetary policy in Nigeria.
Originality/value
To the best of the authors’ knowledge, this is the first study to investigate the existence of a nonlinear Phillip curve in Nigeria.

Abstract
This paper shows how the perceptions of people regarding five dimensions of workplace spirituality (team’s sense of community, alignment with organizational values, sense of contribution to society, enjoyment at work, and opportunities for inner life) predict affective, normative, and continuance commitment, as well as self‐reported individual performance. One sample in Portugal and another in Brazil were collected. The findings show that employees’ perceptions of workplace spirituality predict significant variance of commitment and individual performance in both samples. The empirical evidence suggests that workplace spirituality is a pertinent construct for researchers and an important concern to be taken into account by managers.

Abstract
Purpose
Using public universities as research setting, this study explored whether perception of the prevalence of instrumental ethical climate (IEC) differ among employees based on their gender, age, education levels, job tenure and status.
Design/methodology/approach
Structured survey questionnaires were used in collecting data, and responses from a final sample of 101 senior level university employees were used in the analysis.
Findings
Results of independent t-tests and one-way analysis of variance (ANOVA) showed that although participants had a high overall perception of the presence of IEC in their organisations, statistically significant differences in perception were only found for the gender and education level groups. Furthermore, this research concludes that females are more perceptive of, and sensitive to, the existence of unethical decision-making conditions in their work place, compared to males employees; and that employees with low levels of education are more likely to perceive stronger levels of IECs in their work environment, compared to their more educated counterparts.
Research limitations/implications
Although the sample size is large enough for the kind of inferential analytical method employed in this study, it may not be representative of all the public universities in Nigeria. Furthermore, given that private organisations may encourage different ethical work climates than public establishments, the generalisability of our findings is limited.
Practical implications
To reduce unethical practices in public universities, more women should be encouraged to take up top decision-making positions.
Originality/value
Compared to the general business and public service fields, the current study is one of very few studies that empirically examined individual-level antecedents of ethical climate in African Universities.
