The purpose of this paper is to examine the impact of applying two classical controller strategies, including two proportional (P) controllers with two feedback loops and one proportional–integral–derivative (PID) controller with one feedback loop, on the order and inventory performance within a production-inventory control system.

The simulation experiments of the dynamics behaviour of the production-inventory control system are conducted using a model based on control theory techniques. The Laplace transformation of an Order–Up–To (OUT) model is obtained using a state-space approach, and then the state-space representation is used to design and simulate a controlled model. The simulations of each model with two control configurations are tested by subjecting the system to a random retail sales pattern. The performance of inventory level is quantified by using the Integral of Absolute Error (IAE), whereas the bullwhip effect is measured by using the Variance ratio (Var).

The simulation results show that one PID controller with one feedback loop outperforms two P controllers with two feedback loops at reducing the bullwhip effect and regulating the inventory level.

The production-inventory control system is broken down into three components, namely: the forecasting mechanism, controller strategy and production-inventory process. A state-space approach is adopted to design and simulate the different controller strategy.

The purpose of this study is to propose a new dynamic model of a production-inventory control system. The objective of the new model is to maximise the flexibility of the system so that it can be used by decision makers to design inventory systems that adopt various strategies that provide a balance between reducing the bullwhip effect and improving the responsiveness of inventory performance.

The proposed production-inventory control system is modelled and analysed via control theory and simulations. The production-inventory feedback control system is modelled through continuous time differential equations. The simulation experiments design is conducted by using the state-space model of the system. The Automatic Pipeline Inventory and Order-Based Production Control System (APIOBPCS) model is used as a benchmark production-inventory control system.

The results showed that the Two Automatic Pipelines, Inventory and Order-Based Production Control System (2APIOBPCS) model outperforms APIOBPCS in terms of reducing the bullwhip effect. However, the 2APIOBPCS model has a negative impact on Customer Service Level. Therefore, with careful parameter setting, it is possible to design control decisions to be suitably responsive while generating smooth order patterns and obtain the best trade-off of the two objectives.

This research is limited to the dynamics of single-echelon production-inventory control systems with zero desired inventory level.

This present model is an extension and improvement to Towill’s (1982) and John et al.’s (1994) work, since it presents a new dynamic model of a production-inventory control system which utilises an additional flow of information to improve the efficiency of order rate decisions.

This paper aims to optimise the dynamic performance of production–inventory control systems in terms of minimisation variance ratio between the order rate and the consumption, and minimisation the integral of absolute error between the actual and the target level of inventory by incorporating the Pareto optimality into particle swarm optimisation (PSO).

The production–inventory control system is modelled and optimised via control theory and simulations. The dynamics of a production–inventory control system are modelled through continuous time differential equations and Laplace transformations. The simulation design is conducted by using the state–space model of the system. The results of multi-objective particle swarm optimisation (MOPSO) are compared with published results obtained from weighted genetic algorithm (WGA) optimisation.

The results obtained from the MOPSO optimisation process ensure that the performance is systematically better than the WGA in terms of reducing the order variability (bullwhip effect) and improving the inventory responsiveness (customer service level) under the same operational conditions.

This research is limited to optimising the dynamics of a single product, single-retailer single-manufacturer process with zero desired inventory level.

PSO is widely used and popular in many industrial applications. This research shows a unique application of PSO in optimising the dynamic performance of production–inventory control systems.

Cross-border e-commerce live streaming morphs into an epidemic shopping scenario, yet there is a paucity of research on impulse purchasing in this context. The purpose of this study is to empirically investigate the adoption motivation of cross-border e-commerce live streaming and its influence mechanism on intrinsic response and purchase impulse and to highlight the mediating role of browsing behavior.

Based on the use and gratification lens, a new conceptualization model is established to captivate the theoretical relationships between perceived stimuli, individual attitudes, browsing behavior and impulsive purchases. A questionnaire survey was used to collect cross-sectional data from 427 Malaysian consumers and the estimated framework was validated through AMOS-structural equation modeling technique.

The findings confirm that perceived interactivity, perceived information usefulness and perceived enjoyment significantly influenced positive attitudes toward live-streaming, which in turn induced impulsive purchases; however, perceived affective gratification did not stimulate positive attitudes. Consumers’ utilitarian browsing had a stronger effect on impulse purchases than hedonic browsing and utilitarian browsing behavior mediated the relationship between positive attitudes and impulse buying; however, hedonic browsing had neither a direct nor a mediating effect on impulsive purchases.

This research enhances the literature on the impact of cross-border e-commerce live streaming, an emerging technology, on consumer behavior and offers managerial implications for e-commerce practitioners to gain insights into consumer impulse purchasing behavior.

The findings revamp conventional knowledge and provide new angles for understanding the formation mechanisms of impulse purchases, motivations for virtual media use and browsing behavior mediating effects in the context of live streaming.

The 1896 presidential election between William Jennings Bryan and William McKinley has new salience in the wake of the 2016 presidential contest. We provide the first systematic analysis of presidential voting in 1896, combining county-level returns with economic, financial, and demographic data. We show that Bryan did well where interest rates were high, railroad penetration was low, and crop prices had declined. We show that further declines in crop prices or increases in interest rates would have been enough to tip the Electoral College in Bryan’s favor. But to change the outcome, the additional changes would have had to be large.

Ambient advertising is a unique, intimate and non-traditional form of communication between the product and the consumer; and uses all physical and environmental elements leading to stronger customer engagement. The purpose of this paper is to explore the innovations in ambient advertising including flash mob dancing, use of structures, posters, props, bus tickets, supermarket floors, shopping carts, bank receipts, animals, and other strange and unusual venues in developed economies (e.g. the USA) vs emerging economies (e.g. India).

The research proposes relationship strength (R)-inherent drama (I)-prodigious execution (P) or R-I-P conceptual framework to measure ambient advertising and delves into the R-I-P constructs of ambient advertising.

The results of Study 1 demonstrate that consumers’ global consumption orientation positively influences their attitudes toward ambient advertising. Results from Studies 2 and 3 exhibit interesting comparisons of innovations in ambient advertising between the USA and India; which improves understanding of globalization of ambient advertising in both developed and emerging economies. Relationship strength (R) between the product and the customer strengthens ad believability in both developed and emerging economies; while inherent dramatic surprise (I) displays contrasting results for developed and emerging economies. Prodigious execution (P) results in ad irritation for developed economies while it has no impact for emerging economies.

Overall R-I-P constructs of ambient advertising strengthen brand and ad attitudes and purchase intentions. The research has strong implications for advertising innovations in the USA vis-à-vis India, and demonstrates stronger implications of advertising internationalization across developed and emerging economies.

The research is valuable in the context of emerging and developed economies of the world with respect to ambient advertising. The research explores the trends in ambient advertising and develops measures for testing perceptions of consumers in various world markets toward ambient advertising. The world economies exhibit varying levels of acceptance and appreciation to the global emerging advertising trends, and this presents a huge challenge to the companies worldwide.

This paper aims to give a brief review on behavioral economics and behavioral finance and discusses some of the previous research on agents' utility functions, applicable risk measures, diversification strategies and portfolio optimization.

The authors also cover related disciplines such as trading rules, contagion and various econometric aspects.

While scholars could first develop theoretical models in behavioral economics and behavioral finance, they subsequently may develop corresponding statistical and econometric models, this finally includes simulation studies to examine whether the estimators or statistics have good power and size. This all helps us to better understand financial and economic decision-making from a descriptive standpoint.

The research paper is original.

The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.

The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

Connectedness is essential for student success in online learning. By projecting themselves as real people through video, instructors support connectedness. In this chapter, researchers apply the theory of social presence (Garrison, Anderson, & Archer, 2000) to case studies from two public higher education institutions: a four-year university and a large research university. Analysis identifies video as a humanizing element of online courses. Findings suggest video could be used in a variety of ways (e.g., video lectures, synchronous office hours, weekly overview videos), and no single use of video was perceived to be more or less effective in developing social presence and humanizing the learning experience. However, participants especially perceived connectedness when video was used in a variety of ways. Students from the second case study validated a perception of connectedness to the instructor that faculty in our first case study hoped to achieve. However, one instructor’s perception of disconnect illustrates that video is just one of several pedagogical practices necessary to create a satisfying learning experience for both students and instructors. While video is not the only way to establish social presence, findings suggest video is an effective practice toward creating a humanized and connected online learning community.

Findings from a comparative qualitative study with parents in the USA and China increase the understanding of experiences of adults with autism in both countries.

Semi-Structured interviews were conducted with families in the USA and in China. In total, 18 families participated in the study – 7 in the USA, 11 in China.

Analysis of the comparative data led to the emergence of three overarching themes, expressing both similarities and differences in experiences: 1) transition to adult services plays out differently in the two nations, 2) parent advocacy and efforts in supporting and securing services for their children are strong in both countries but are also defined by the variability in access to services and 3) due to the scarcity of adult services in their country, Chinese parents express significantly more worries about their own aging and mortality as compared with USA parents.

Practical implications and directions for future research are discussed.

By examining the experiences of families of adults with autism in the USA and China, the research reveals themes that would not be visible in a single-nation study.
