Companies increasingly have to adapt new technology and design new business models to retain their competitive advantage in highly dynamic environments. The increasing pervasiveness of the Internet of things (IoT) has offered great potential in many different areas of application to lead or complement new business models. However, business models based on largely static, single firm or historical information architectures are facing challenges in today's more dynamic environment as new ways of creating value arise across industries and between firms, clients and other stakeholders. Embracing the business ecosystem concept is now becoming critical in order to realize business opportunities or business model potential. This paper focuses on the elaboration of the business ecosystem concept in the IoT business model environment, from both academic and practitioners' perspectives, to analyse how IoT business models are connected to the underlying business ecosystem. We analyse three cases from the elevator industry to explain how different business models are employed in connection with business and IoT ecosystems, as well as their challenges and possible options to overcome these challenges.

Introduction: This article describes the process and evaluation of a smoking cessation support programme for mental health clients in Sydney.Aim: The objective of the study was to assess a group-based smoking cessation support model for community mental health clients.Methods: Two community mental health services participated; 29 clients received free NRT products and weekly education for 12 weeks on: effects of smoking, nicotine dependence, NRT use, withdrawal process and the benefits of quitting. Evaluation included face-to-face interviews, telephone or postal survey using a semi-structured questionnaire.Results: The baseline (n = 29) and follow-up (n = 14) surveys showed reduction in the number of cigarettes (30 to 21) smoked a day (55% vs. 36%). At one month 47% (n = 19) were confident about stopping smoking permanently whereas 19% (n = 14) reported the same after six months. Participants reported concerns of health effects, illness, physical symptoms (77% n = 27) and financial cost (93% n = 27) were the motivating factors in quitting. None of the findings was statistically significant.Conclusions: Community based interventions to address the rate of smoking in this group is needed. Financial and health benefits can be used as motivating factors, and integration of smoking cessation assistance in treatment and rehabilitation of mental health consumers would be useful.

Background According to the theory of compensating differentials, caregivers with high levels of intrinsic motivation should exhibit a higher-than-average satisfaction with their pay. Whereas studies conducted in Western countries have provided empirical evidence for the theory of compensating differentials in various care settings, few studies have been conducted in China that focus on caregivers employed in residential homes for the elderly (RHE). The sociodemographic characteristics of caregivers in China different significantly from their counterparts in Western countries. Purpose This study was developed to analyze the mediating role of job burnout to assess the influence of intrinsic motivation on pay satisfaction among caregivers in RHE. Methods Structural equation modeling was used to examine the influences of intrinsic motivation on pay satisfaction in a sample of 1,212 caregivers employed in RHE in China by analyzing the mediating role of job burnout. Results Intrinsic motivation was found to relate positively to pay satisfaction (β = .11, p < .05). Negative relationships were identified between intrinsic motivation and job burnout (β = −.46, p < .01) and between job burnout and pay satisfaction (β = −.13, p < .01). Job burnout was found to have a significant mediating effect on the relationship between intrinsic motivation and pay satisfaction (β = .06, p < .01). Conclusions/Implications for Practice A significant relationship was found between intrinsic motivation and pay satisfaction, with job burnout playing a mediating role in caregivers employed in RHE in China. This research has profound implications for nursing education, practice, and research. First, greater efforts should be focused on instilling nursing values in nursing students to foster intrinsic motivation. Second, nonpecuniary rewards may be offered to caregivers to acknowledge the values of care work and strengthen intrinsic motivation. Third, a supportive working climate should be fostered to reduce job burnout. Fourth, caregivers should be informed of their rights to decent pay and their right to bargain collectively through unions. Fifth, appropriate public policies should be implemented to provide pay for caregivers at levels that recognize and appreciate their intrinsic motivation.

With the widespread application of location-based service (LBS) technology in the urban Internet of Things, urban transportation has become a research hotspot. One key issue of urban transportation is the nearest neighbor search of moving objects along a road network. The fast-updating operations of moving objects along a road network suppress the query response time of urban services. Thus, a tree-indexed searching method is proposed to quickly find the answers to user-defined queries on frequently updating road networks. First, a novel index structure, called the double tree-hash index, is designed to reorganize the corresponding relationships of moving objects and road networks. Second, an index-enhanced search algorithm is proposed to quickly find the k -nearest neighbors of moving objects along the road network. Finally, an experiment shows that compared with state-of-the-art algorithms, our algorithm shows a significant improvement in search efficiency on frequently updating road networks.
