Abstract
In this study, the authors investigate methods of sequential analysis to test prospectively for the existence of a unit root against stationary or explosive states in a p-th order autoregressive (AR) process monitored over time. Our sequential sampling schemes use stopping times based on the observed Fisher information of a local-to-unity parameter. In contrast to the Dickey–Fuller (DF) test statistic, the sequential test statistic has asymptotic normality. The authors derive the joint limit of the test statistic and the stopping time, which can be characterized using a 3/2-dimensional Bessel process driven by a time-changed Brownian motion. The authors obtain their limiting joint Laplace transform and density function under the null and local alternatives. In addition, simulations are conducted to show that the theoretical results are valid.

Abstract
Purpose
The purpose of paper is to investigate the institutional features of the leasehold system of Hong Kong, which is predicated on the freedom of contract as an institutional arrangement for land management and planning that promotes sustainable development.
Design/methodology/approach
The approach is analytical, using concepts of property rights informed by Coasian neo‐institutional economics and the ideas of Yu et al. on the Schumpeterian process in innovation.
Findings
It was demonstrated that the post‐contractual imposition of statutory planning control on the leasehold land management system in Hong Kong has adversely affected and adaptability of the leasehold system in achieving sustainability.
Research limitations/implications
This paper encourages a reinterpretation of statutory zoning in areas with a leasehold system and the reception of the land lease as a basis for innovations that help promote sustainable development.
Practical implications
This paper warns against legislative activism in planning controls as that can destroy or erode the basis for innovations that help promote sustainable development.
Originality/value
Using the idea of innovations of Yu et al. and Lai and Lorne, this paper further develops Lai theory of “planning by contract” as an alternative to “planning by edict”.

Abstract
Purpose
In this paper, the authors examined the changes in labour unrest and labour quality brought by high labour standards over a considerable period in Taiwan. Then, the authors studied the role of these changes in predicting the inflow of foreign direct investment (IFDI) in the country. To test the role, the authors measured the differences in effects of the two changes on wages, working hours and employment opportunities of skilled female and skilled male workers in FDI-intensive and non-intensive industries.
Design/methodology/approach
Using a model built on pooled cross-sectional time-series data from 1999 to 2012, the authors measured the effect of changes in labour unrest and the presence of skilled workers on the net inflow of FDI. Using data from the Manpower Utilisation Survey (MUS), the authors applied differences–in–Differences-in--ddifferences- (DDD) and differences–in–Differences-in-ddifferences-in--differences- (DDDD) estimation methods to test the effect of changes in labour unrest and labour quality on three labour market outcomes, namely wages, working hours and job opportunities of skilled workforce.
Findings
Increasing labour unrest affected the employment opportunities of almost every unemployed person seeking skilled jobs in Taiwan. When the authors compared the adverse effect of high labour standards on employment opportunities and working hours, the authors found women looking for skilled jobs in foreign-owned firms to be the worst affected. Besides, foreign firms paid different wages to skilled educated men than what foreign firms' domestic counterparts paid to skilled educated men employed in Taiwanese firms.
Practical implications
An in-depth analysis of changes in labour unrest and presence of skilled workers because of high labour standards and the extent to which such changes helped the nation to attract FDI should be useful to policymakers interested in understanding the impact of legislative measures and policy reforms on labour market outcomes across industry types, which matter to foreign investors. If changes in labour unrest and labour quality influenced the inflow of FDI more to firms in one set of industries than the others, the same should have a bearing on revamping of future enactment and enforcement in Taiwan.
Originality/value
Current study findings would not only provide broad lessons to policymakers in Taiwan but findings of the authors' country case study should be able to guide growing economies that are equally careful whilst raising the labour standards as most fear that high labour standards can deter inflow of FDI because of increasing labour cost.

Abstract
Purpose
Females with autism spectrum disorder (ASD) may display superficial social skills which may mask their ASD symptomology impacting on the identification of the disorder – known as the “camouflage” hypothesis. Compared to males with ASD, it is increasingly recognised that females with ASD have a stronger ability to imitate behaviour which is socially acceptable, particularly those females who have higher cognitive abilities (i.e. intelligence considered to be within the normal range) (Ehlers and Gillberg, 1993). The paper aims to discuss this issue.
Design/methodology/approach
This paper will explore the literature on camouflaging or masking behaviour in females with ASD. A systematic PRISMA review was conducted.
Findings
The capacity to “camouflage” social difficulties in social situations is considered to be one of the main features of the female phenotype of ASD (e.g. Kenyon, 2014). Social imitation or camouflaging enables some level of success and coping, which results in some females never receiving a diagnosis of ASD. They typically may not exhibit any observable functional impairments. However, under the surface of the camouflage, females may experience high levels of subjective stress, anxiety and exhaustion and a need to re-charge or recuperate by withdrawing from any social interaction.
Research limitations/implications
There is relatively little understanding and knowledge of the female phenotype of ASD. This lack of understanding and knowledge impacts significantly on the ability to identify females with ASD (Lai et al., 2015; Bargiela et al., 2016), which can have a number of negative consequence (Adamou et al., 2018; National Collaborating Centre for Mental Health (UK), 2012).
Practical implications
There is a need for the development of a camouflaging measure.
Originality/value
There is a real need for further research exploring the positive and negative impact of the phenomenon of “camouflaging”, or “pretending to be normal” in females with ASD.

Abstract
The objective of this study is to investigate how country risk, different political actions from the government and bureaucratic behavior influence the activities in industry supply chains (SCs) in emerging markets. The main objective of this study is to investigate the influence of these external stakeholders’ elements to the demand-side and supply-side drivers and barriers for improving competitiveness of Ready-Made Garment (RMG) industry in the way of analyzing supply chain. Considering the phenomenon of recent change in the RMG business environment and the competitiveness issues this study uses the principles of stakeholder and resource dependence theory and aims to find out some factors which influence to make an efficient supply chain for improving competitiveness. The RMG industry of Bangladesh is the case application of this study. Following a positivist paradigm, this study adopts a two phase sequential mixed-method research design consisting of qualitative and quantitative approaches. A tentative research model is developed first based on extensive literature review. Qualitative field study is then carried out to fine tune the initial research model. Findings from the qualitative method are also used to develop measures and instruments for the next phase of quantitative method. A survey is carried out with sample of top and middle level executives of different garment companies of Dhaka city in Bangladesh and the collected quantitative data are analyzed by partial least square-based structural equation modeling. The findings support eight hypotheses. From the analysis the external stakeholders’ elements like bureaucratic behavior and country risk have significant influence to the barriers. From the internal stakeholders’ point of view the manufacturers’ and buyers’ drivers have significant influence on the competitiveness. Therefore, stakeholders need to take proper action to reduce the barriers and increase the drivers, as the drivers have positive influence to improve competitiveness.
This study has both theoretical and practical contributions. This study represents an important contribution to the theory by integrating two theoretical perceptions to identify factors of the RMG industry’s SC that affect the competitiveness of the RMG industry. This research study contributes to the understanding of both external and internal stakeholders of national and international perspectives in the RMG (textile and clothing) business. It combines the insights of stakeholder and resource dependence theories along with the concept of the SC in improving effectiveness. In a practical sense, this study certainly contributes to the Bangladeshi RMG industry. In accordance with the desire of the RMG manufacturers, the research has shown that some influential constructs of the RMG industry’s SC affect the competitiveness of the RMG industry. The outcome of the study is useful for various stakeholders of the Bangladeshi RMG industry sector ranging from the government to various private organizations. The applications of this study are extendable through further adaptation in other industries and various geographic contexts.

Abstract
Smart card-based E-payment systems are receiving increasing attention as the number of implementations is witnessed on the rise globally. Understanding of user adoption behavior of E-payment systems that employ smart card technology becomes a research area that is of particular value and interest to both IS researchers and professionals. However, research interest focuses mostly on why a smart card-based E-payment system results in a failure or how the system could have grown into a success. This signals the fact that researchers have not had much opportunity to critically review a smart card-based E-payment system that has gained wide support and overcome the hurdle of critical mass adoption. The Octopus in Hong Kong has provided a rare opportunity for investigating smart card-based E-payment system because of its unprecedented success. This research seeks to thoroughly analyze the Octopus from technology adoption behavior perspectives.
Cultural impacts on adoption behavior are one of the key areas that this research posits to investigate. Since the present research is conducted in Hong Kong where a majority of population is Chinese ethnicity and yet is westernized in a number of aspects, assuming that users in Hong Kong are characterized by eastern or western culture is less useful. Explicit cultural characteristics at individual level are tapped into here instead of applying generalization of cultural beliefs to users to more accurately reflect cultural bias. In this vein, the technology acceptance model (TAM) is adapted, extended, and tested for its applicability cross-culturally in Hong Kong on the Octopus. Four cultural dimensions developed by Hofstede are included in this study, namely uncertainty avoidance, masculinity, individualism, and Confucian Dynamism (long-term orientation), to explore their influence on usage behavior through the mediation of perceived usefulness.
TAM is also integrated with the innovation diffusion theory (IDT) to borrow two constructs in relation to innovative characteristics, namely relative advantage and compatibility, in order to enhance the explanatory power of the proposed research model. Besides, the normative accountability of the research model is strengthened by embracing two social influences, namely subjective norm and image. As the last antecedent to perceived usefulness, prior experience serves to bring in the time variation factor to allow level of prior experience to exert both direct and moderating effects on perceived usefulness.
The resulting research model is analyzed by partial least squares (PLS)-based Structural Equation Modeling (SEM) approach. The research findings reveal that all cultural dimensions demonstrate direct effect on perceived usefulness though the influence of uncertainty avoidance is found marginally significant. Other constructs on innovative characteristics and social influences are validated to be significant as hypothesized. Prior experience does indeed significantly moderate the two influences that perceived usefulness receives from relative advantage and compatibility, respectively. The research model has demonstrated convincing explanatory power and so may be employed for further studies in other contexts. In particular, cultural effects play a key role in contributing to the uniqueness of the model, enabling it to be an effective tool to help critically understand increasingly internationalized IS system development and implementation efforts. This research also suggests several practical implications in view of the findings that could better inform managerial decisions for designing, implementing, or promoting smart card-based E-payment system.

Abstract
The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.
The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.
In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.
The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.

Abstract
Purpose
The purpose of this paper is to develop a hypothesis for evaluating the potential contribution of planning conditions to protect the environment by reducing environmental complaints (ECs) in an institutional context of growing communicative planning and interpret the results of an empirical study using two received hypotheses in terms of sustainable development in the light of the actual participation of the public in influencing the formulation of planning conditions.
Design/methodology/approach
The hypothesis is tested using Environmental Protection Department EC and Planning Department zoning data. In addition, field observation of the conduct the Town Planning Board in their open sessions is made over a period of 27 months.
Findings
The hypothesis about the frequency of planning permissions and the incidence of ECs using the “received” model of Lai is refuted. The results for testing Lai's model on the relationship between Comprehensive Development Area zoning and ECs are indecisive. Though a negative correlation between zoning and complaints is established, the strength of such correlation is insignificant for each of the specified periods.
Research limitations/implications
The promise of communicative theorists about empowering the public in planning has yet to be fulfilled in terms of contribution to the shaping of planning conditions. Official suppression of addresses of locations of the occurrence of ECs does not allow the ideal hypothesis to be tested.
Practical implications
Subject to further and better qualitative research, the limitations of the new public participation law in planning for shaping planning conditions are revealed by an examination of observed facts about the time spent by the Town Planning Board in decision making and the nature of the planning conditions imposed in response to public comments.
Originality/value
The paper demonstrates an approach to evaluate the direct means of measuring the relationship between externalities and zoning with a view to interpret the contribution of planning conditions to sustainable development.

Abstract
Purpose
The purpose of this paper is to find the optimal power structure that drives green practices in the supply chain and coordinate the costs and benefits of green practices in supply chain under different power structures.
Design/methodology/approach
This paper developed a supply chain of one supplier and one manufacturer, in which the supplier and the manufacturer are responsible for the “greening” of products. Then, the game theory modeling method is used to explore the influence of different power structures on green practices in the supply chain. Finally, the authors developed a green cost-sharing contract made by the leader; regarding optimal supply chain profits and green performance, the proposed contracts and the non-coordination situation are compared and tested by a numerical simulation.
Findings
The increase of the green practice difficulty of any member in the supply chain will not only reduce the greenness of products at that stage but will also reduce the green investment of the supply chain partner. Becoming a channel leader does not necessarily mean being more profitable than being a follower, and when the green practice difficulty of the leader is less than a certain threshold, ceding dominant power to the follower may benefit both sides. A green cost-sharing contract made by the leader is not necessarily beneficial to all enterprises.
Originality/value
This paper helps to better understand the role of the power relation in realizing the industry's green goals and helps decision-makers to achieve win-win cooperation by adjusting power relations and optimizing green cost-sharing contracts.
