PM10 is one of the most dangerous air pollutants which is harmful to the ecological system and human health. Accurate forecasting of PM10 concentration makes it easier for the government to make efficient decisions and policies. However, the PM10 concentration, particularly, the emerging short-term concentration has high uncertainties as it is often impacted by many factors and also time varying. Above all, a new methodology which can overcome such difficulties is needed.

The grey system theory is used to build the short-term PM10 forecasting model. The Euler polynomial is used as a driving term of the proposed grey model, and then the convolutional solution is applied to make the new model computationally feasible. The grey wolf optimizer is used to select the optimal nonlinear parameters of the proposed model.

The introduction of the Euler polynomial makes the new model more flexible and more general as it can yield several other conventional grey models under certain conditions. The new model presents significantly higher performance, is more accurate and also more stable, than the six existing grey models in three real-world cases and the case of short-term PM10 forecasting in Tianjin China.

With high performance in the real-world case in Tianjin China, the proposed model appears to have high potential to accurately forecast the PM10 concentration in big cities of China. Therefore, it can be considered as a decision-making support tool in the near future.

This is the first work introducing the Euler polynomial to the grey system models, and a more general formulation of existing grey models is also obtained. The modelling pattern used in this paper can be used as an example for building other similar nonlinear grey models. The practical example of short-term PM10 forecasting in Tianjin China is also presented for the first time.

In this qualitative study, we explore 31 preservice teachers’ generative trajectories including how they built on instructional practices learned in the service-learning project, the university methods course, and the field-based experience. We addressed the question: In what ways does participating in a semester-long field-based university course combined with a service-learning program shape preservice teachers’ views about effective literacy practices for emergent bilinguals? We identified four themes in our analysis: importance of choice in literacy pedagogy; learning from and with our students; freedom to apply course methods and ideas; and growing confidence and align them with Ball’s (2009) generative change model and the four processes of change – metacognitive awareness, ideological becoming, internalization, and efficacy.

We found the preservice teachers’ ability to develop an awareness of diversity grew from their work with students both in their field-block experience and writing club. These opportunities provided them with a layering of learning – from course readings, collaborating with teachers, to problem solving and creating lessons that specifically met their students’ needs. By moving in and out of different contexts, preservice teachers developed generative knowledge about ways to support writing for emergent bilinguals. Likewise, they became keenly aware of their own experiences and beliefs. Implications include the importance of providing a variety of opportunities for preservice teachers to work directly with students. This should be accompanied by written and verbal discussions to examine and critique their experiences and ideologies in relation to students’ language and literacy needs.

Studies which look at disaster affected people’s use of communications technologies often fail to take into account people’s communication rights in their analyses, particularly their right to freedom of expression. The purpose of this paper is to draw attention to this issue by exploring the link between freedom of expression, community participation and disaster risk reduction in the use of digital feedback channels offered by aid and government agencies in the aftermath of Typhoon Haiyan.

Ethnographic fieldwork was undertaken in the Philippines between 2014 and 2015 in Tacloban City and Sabay Island, both in the Visayas, which have been affected by Typhoon Haiyan. A total of 101 in-depth interviews were conducted with affected people, local and national officials, community leaders, civil society groups, telecommunications companies and humanitarian agencies.

The interviews reveal that majority of disaster-affected Filipinos chose not to engage with formal feedback platforms offered by government and aid agencies out of fear of giving critical feedback to those in authority. They were concerned about the possibility of losing their entitlement to aid, of being reprimanded by government officers, and of the threat to their lives and of their loved ones if they expressed criticism to the government’s recovery efforts. Nonetheless, 15 per cent used backchannels while 10 per cent availed of the formal means to express their views about the recovery.

The paper sought to draw links between people’s lack of engagement with the formal feedback mechanisms offered by government and aid agencies in the wake of Haiyan and the restrictive sociopolitical environment in the Philippines. Further research could be undertaken to examine how freedom of expression plays a role in disaster prevention and mitigation. Research into this area could potentially provide concrete steps to help prevent the occurrence of disasters and mitigate their impacts.

Freedom of expression and its place in disaster risk reduction is rarely explored in disaster studies. The paper addresses this oversight by examining the lack of engagement by communities affected by Haiyan with digital feedback channels provided by aid agencies and government. The findings suggest that despite the provisions for community participation in DRR under the Philippine Disaster Law, people are prevented to express criticism and dissent which puts into question the spirit and purpose of the law.

In the 1982, ruling of Plyler v. Doe the Supreme Court of the United States ruled that undocumented children cannot be denied a public education. Yet, as this chapter is being written in 2015, states across the United States have passed statutes preventing the education of these children and by practical extension documented children and their families. A package of Executive Actions by President Obama in November of 2014 modestly benefited and impacted the rights of undocumented immigrants, but did not challenge the state laws affecting school children and university students. In this chapter, we will review the rights to education of immigrant children. We will review the national scene as it stands amidst confusion in the absence of meaningful immigration reform by the U.S. Congress and the puzzle of the states arbitrarily denying rights flowing from the Fifth and Fourteenth Amendments of the United States Constitution, carefully articulated in Plyler. We intend to present a blunt portrait of rights denied and children left behind.

The paper presents the development of a continuous improvement process for the customer relations department at Severn Trent Water in the UK. In‐company research was carried out to identify the main barriers to continuous improvement in the areas of leadership, training, communication, motivation, teamwork, and change management. The study concluded that the company should develop an organisational culture and management style to support continuous improvement of daily working processes, and that change should be managed against the achievement of appropriate quality targets. A continuous improvement process was developed based on a structured problem‐solving model incorporating the application of established quality tools, to be applied by problem solving teams from the customer relations department. It was recommended that the team members should be trained in the problem solving process, and the related quality tools and techniques. Also, management should lead and support this approach by concentrating on team (rather than individual) performance achievement.

The study aims to identify, analyse and develop a model for measuring the inter-relationship and interaction among the inter-partner factors. International joint ventures (IJVs) literature has scantly studied the interactions and inter-relationships among the inter-partner factors of IJVs performance. To address this gap, this research creates a hierarchical relationship framework among the inter-partner factors of IJVs performance.

The comprehensive literature review is used to identify the factors and possible relationships between the factors and IJVs performance. M-TISM (modified total interpretive structural modelling) methodology is used to examine the relationship among the factors of IJVs performance.

This study highlights 12 inter-partner factors that affect IJVs performance. The results suggest that size asymmetry, commitment, goal incongruency, competitive overlap, trust, control, the interdependency of resources, cooperation, economic distance, cultural distance, geographical distance and administrative distance significantly impact IJVs performance. Commitment is found to be a linkage variable as it has high dependence and driving power. Goal incongruency and competitive overlap have high driving power.

This study gives a proposed list of critical inter-partner factors for policymakers and practitioners to consider when developing rules or recommendations to improve IJVs performance. The focus of policymakers should be on economic and geographical distance, followed by cultural distance, competitive overlap, goal incongruency, size asymmetry and administrative distance to improve inter-relationship among the partners in IJVs. The work contributes to the academician by presenting a modified TISM model that highlights the significance of ambidexterity in driving the performance of IJVs.

This study fills a gap in the literature by analysing the interactions among the inter-partner parameters that influence the performance of IJVs. It offers insights into the variables, such as driver dependence and the relationships between the variables.

Interest in reverse innovation (RI) is increasing. According to the authors’ review, more than 350 reliable sources (scientific publications, academic books and working papers) examine or at least discuss the concept. As RI gains popularity among academic authors, some discrepancies have started to appear. This wealth of publications could impact prior advancements related to understanding of the phenomenon. The purpose of this paper is to decrease fragmentation and focus on identifying and understanding RI.

A systematic review of RI was conducted. The review conformed to a rigorous set of core principles: it was systematic (organized according to a method designed to address the review questions), transparent (explicitly stated), reproducible and updatable, and synthesized (summarized the evidence relating to the review question).

This systematic review provides an improved theoretical and practical framework for the concept of RI. In terms of theory, the authors have demonstrated that the idea behind the concept is not entirely new. A consensus on the definition of RI is not reached in the literature, and descriptions in organizational theory contexts are sometimes misleading. The authors analyzed all the various definitions provided in the literature. From a practical point of view, the authors have explained the academic interest in RI in relation to organizational strategy, in particular the context in which strategies are adopted. The concept of RI has significant managerial implications, and the authors have proposed a conceptual framework to help managers understand and grasp the implications of RI. Finally, the authors have provided suggestions for future research on RI.

To the best of the authors’ knowledge, this is the first exhaustive literature review on RI.
