Being at the heart of modern pulp mills, continuous pulp digesters have attracted much attention from the research community. In this article, a comprehensive review in the area of modeling, control and diagnostics of continuous pulp digesters is conducted. The evolution of research focus within these areas is followed and discussed. Particular effort has been devoted to identifying the state-of-the-art and the research gap in a summarized way. Finally, the current and future research directions in the areas have been analyzed and discussed. To date, digester modeling following the Purdue approach, Kappa number control using model predictive controllers and health index-based diagnostic approaches by utilizing different statistical methods have dominated the field. While the rising research interest within the field is evident, we anticipate further developments in advanced sensors and integration of these sensors for improving model prediction and controller performance; and the exploration of different AI-based approaches will be at the core of future research.

Research Gap

PurposeThis study conceptualises the construct – green competencies. The concept is in the niche stage and needs further elaboration. Hence, to address the research gap, this study follows the steps proposed by Tranfield et al. (2003). The major part of the study comprises descriptive analysis and thematic analysis. Descriptive analysis of the selected 66 articles was examined with the classification framework, which contains year-wise distribution, journal-wise distribution, the focus of the concept, the economic sector, and dimensions of sustainable development. The paper conducts a thematic analysis of the following research questions. What are the green competencies and their conceptual definition? What are their dimensions?Design/methodology/approachThis paper applies a systematic literature review of green competencies literature, extends the state-of-the-art using the natural resource-based view, and discusses future research directions for academicians and practitioners.FindingsIn recent years, there was considerable interest in green competencies (GC), as reflected in the surge of articles published in this genre. This paper asserts that green competencies are a multidimensional construct comprised of green knowledge, green skills, green abilities, green attitudes, green behaviours, and green awareness.Originality/valueDespite the significance of green competencies, there has been a dearth of study to define the constructs and identify the dimensions. Hence, this study addresses the literature gap by conceptualisation and discusses dimensions of the construct.

Research Gap

Recent political developments suggest that political followership has played increasingly vital roles in modern democratic politics. However, scholarship seemingly lacks proper conceptual and methodological tools for analysing why and how citizens follow their leaders, and what the role of this relationship is in personalised politics and political leadership. Addressing the research gap, this article turns to generic leadership studies for help and introduces its follower-centric models into the field of political science. This venture opens with a review and comparison of some of the different perspectives about political followers in the scholarship on political leadership and personalisation, taking account of their limitations. It then moves on to assess follower-centric models and their empirical results, focusing on observers’ perceptions about the characteristics and behaviours of leaders in the attribution of leadership. Based on these models, the article offers a balanced perspective about leader–follower relations. Recommendations for future research directions are presented in the concluding sections.

Innovation in formal and practical learning is an accepted progression and its adoption in learning methodologies is a sign that a respective society is open to new technologies, ideas, and, thus, to advancement. The latest innovation in teaching is the use of Augmented Reality. Applications using this technology have been deployed successfully in STEM(Science, Technology, Engineering, and Mathematics) education for delivering the practical and creative parts of the education. Since Augmented Reality technology has already a large volume of published studies about education that reports advantages, limitations, effectiveness, and challenges of AR in education, classifying these projects will allow for a review of the success of Augmented Reality integration in the different educational settings and discover current challenges and future research areas.<div>The main findings of this paper are the generation of a detailed taxonomy of the current literature which outlines the current challenges, the use of this taxonomy to identify future research areas, and finally to report on the development of two case studies that can highlight the first steps need to address these research areas. The result of this research ultimately is to detail the research gap that is needed to be filled to facilitate real-time touchless hand interaction, kinesthetic learning, machine learning agents with a remote learning pedagogy.</div>
