When it comes to the high accuracy autonomous motion of the mobile robot, it is challenging to effectively control the robot to follow the desired trajectory and transport the payload simultaneously, especially for the cloud robot system. In this paper, a flexible trajectory tracking control scheme is developed via iterative learning control to manage a distributed cloud robot (BIT-6NAZA) under the payload delivery scenarios.

Considering the relationship of six-wheeled independent steering in the BIT-6NAZA robot, an iterative learning controller is implemented for reliable trajectory tracking with the payload transportation. Meanwhile, the stability analysis of the system ensures the effective convergence of the algorithm.

Finally, to evaluate the developed method, some demonstrations, including the different motion models and tracking control, are presented both in simulation and experiment. It can achieve flexible tracking performance of the designed composite algorithm.

This paper provides a feasible method for the trajectory tracking control in the cloud robot system and simultaneously promotes the robot application in practical engineering.

Process models are a valuable tool in the design and configuration of enterprises. However, current modeling techniques have shortcomings that prevent them from fully supporting the analysis required to design an enterprise. This is especially true when considering the needs of modeling highly distributed and temporary multi‐company enterprises such as fractal or virtual enterprises. This paper presents a modeling scheme that supports a process‐centered approach to the analysis and design of both conventional and extended enterprises. Using a holon‐based approach to model the components of an enterprise, it allows for the development of integrated business rule, activity, resource, business process, and organizational views of the enterprise using the IDEF suite of modeling methods. The scheme is built around a central IDEF5 model of the enterprise from which the other views are extracted. The paper also describes the technique for developing an enterprise model using the scheme.

Entrepreneurship and leadership may flow from the same genealogical source and the appearance of separation of the two constructs may be due to differences in the contexts through which the root phenomenon flows. Entrepreneurship and leadership are figuratively different manifestations of the need to create. To better understand the origin of entrepreneurship and leadership, research must first focus on the combinations or hierarchy of traits that are necessary, but perhaps not sufficient, to stimulate the two constructs. Factors that trigger a drive to create or take initiative within the individual in the context of a particular circumstance should be identified, and the situational factors that move the individual toward more traditional leader or classic entrepreneurial-type behaviors need to be understood.

Set in a Mexican-American community of a US Gulf Coast state, the purpose of this paper was to describe how three young siblings and their family members constructed their spiritual, ethnic and communicative identities within the context of a virtual family literacy program during COVID-19.

This project was approached as an illustrative case study that focused on one family’s engagement with a children’s book in which the protagonists retell the legend of the Catholic patroness of the Americas, Our Lady of Guadalupe.

The case study illustrates how the children's spiritual/religious identities were inseparably intertwined with their home literacy practices and their identities as communicators with others. The children’s everyday spiritual/religious practices, routines and activities motivated familial conversations and dialogue that engage and support children’s literacy development.

Although there is a large corpus of scholarship about secular early literacy program for families with preschool children, there are few that describe the recognition and inclusion of families’ spiritual/religious identities.

This study aimed to examine factors associated with electronic cigarette use among adolescents aged 15–19 in Jakarta, Indonesia.

The study was a school-based survey involving 1,318 students from 14 high schools in Jakarta. A multistage cluster sampling methodology was used. The authors used the chi-square test and multiple logistic regression to examine the association between electronic cigarette use and sociodemographic, social influences, health risk perceptions, availability, affordability and conventional cigarette smoking status.

Overall, 6.3% of females and 29% of males reported ever having used electronic cigarettes. Electronic cigarette use was independently associated with sex, school locations, conventional cigarette smoking status, peer use, availability and perceptions that electronic cigarettes aid conventional cigarette smoking cessation. Compared with non-smokers, lifetime (AOR: 8.740, 95% CI: 5.126–14.901) and current conventional cigarette smokers (AOR: 18.380, 95% CI: 10.577–31.938) were more likely to use electronic cigarettes.

The use of electronic cigarettes among adolescents was considerably high in this study. Therefore, the tobacco control policy should be extended to regulate the marketing and use of all types of tobacco products and not just conventional cigarettes.

The study explored beyond individual lifestyle factors that contributed to electronic cigarette use in Indonesia such as affordability, school locations and availability of electronic cigarettes. These issues have not been specifically discussed in previous studies.

As the quality of the environment decreases, enterprises and consumers' awareness of environmental protection is constantly improving. More and more enterprises begin to increase their investment in carbon emission reduction and attract environmentally friendly consumers to buy low-carbon products through advertising. The purpose of this paper is to utilize a realistic differential game model to provide dynamic carbon emission reduction strategies, advertising strategies and cooperation methods for complex supply chain members from a long-term perspective.

This paper uses the extend Vidale-Wolfe model (V-W model) to discuss the dynamic joint emission reduction strategy in the supply chain.

(1) When consumers' awareness of environmental protection increases, on the whole, carbon emission reduction and profit of products show an upward trend. (2) From a long-term perspective, the manufacturer's advertising subsidy to one of the retailers is the best choice. If the strength of the two retailers is unbalanced, the manufacturer will choose to cooperate with the dominant retailer. (3) Advertising, as a marketing means for retailers to promote low-carbon products, can alleviate the adverse effects of prisoner's dilemma in a semi-cooperative state, but it cannot achieve the Pareto optimization result.

This paper focuses on the analysis of the situation that when the manufacturer is the leader and thinks that consumers are active advocates of low-carbon products.

The results of this paper can provide theoretical basis for the joint emission strategy of supply chain members in low-carbon environment.

This empirical study examined links between entrepreneurial personality traits and perception of new venture opportunity in a sample of 207 respondents. Four entrepreneurial personality traits were included to predict respondents℉ perception of new venture opportunity. They are (1) achievement motivation, (2) locus of control, (3) risk propensity, and (4) proactivity.The results of multiple regression analysis show that three of the four entrepreneurial personality traits‐locus of control, risk propensity, and proactivity‐related significantly to perception of new venture opportunity in expected directions. Among the three personality traits, proactivity was found to have the strongest influence over entrepreneurial perception. No significant relationship was found between achievement motivation and perception of new venture opportunity. Among six control variables, only work experience was found to influence perception of new venture opportunity. This study explored links between entrepreneurial personalities and cognition and its results suggest that a combination of trait and cognition approaches contributes to a better understanding of entrepreneurial decision-making process. Both theoretical and practical implications were discussed.

In this research a group of Iranian entrepreneurs was studied using survey questionnaires as well as interviews. The entrepreneurs' locus of control and their perceptions regarding major problems facing them were examined. The results indicated that our sample overall had internal locus of control. The significance of this finding in the context of a religiously dominated culture is discussed. The entrepreneurs also indicated the lack of market information and government role as major hurdles facing entrepreneurial activities.

Recent interest in social entrepreneurship among young people has led to a heightened interest in new research. Few studies, however, have yet to investigate motivators of involvement, particularly from countries that are new to social entrepreneurship. The current study set out to better understand this phenomenon among young social entrepreneurs in Malaysia. In-depth one-to-one interviews with 12 young entrepreneurs were carried out to collect the data. Four themes and ten sub-themes emerged from the interviews, including early life experience (childhood experience and family experience), inspiration from clients and colleagues (interactions with the target group and exposure to social entrepreneurs), work-related experience (volunteer experience and job-related experience), and personal meaning (contribute back to society, desire for more meaning in life, and personal passions). The implications for policy-makers and interested parties are outlined in regard to enhancing participation and interest among youth for social entrepreneurship.
