The capacity of coal to adsorb methane is greatly affected by temperature and, in recent years, temperature-dependent adsorption has been studied by many researchers. Even so, comprehensive conclusions have not been reached and conflicting experimental results are common. This paper reviews the current state of research regarding the temperature-dependent adsorption of methane in coal and catalogs the conclusions from experiments conducted on that subject by 28 researchers, as published between 1995 and 2017. Probability theory and statistics are used to show that the conclusion generally accepted by most researchers is that the amount of methane adsorbed by coal decreases with increasing temperature. It is highly likely that the Langmuir volume decreases as the temperature rises, and it is also probable that the Langmuir pressure increases at higher temperatures. Equations are presented that express the relationships between methane adsorption, Langmuir volume, Langmuir pressure, and temperature. Future research should be directed toward determining the relationship between Langmuir pressure and temperature. The results of the study presented herein provide a theoretical basis for predicting the gas content in coal seams and improving the efficiency of coalbed methane development.

PurposeThe purpose of this paper is to systematise the current state of research on the association between companies’ corporate social responsibility (CSR) engagement and financial analysts’ company assessment. Additionally, it aims to identify fruitful directions for future research that contribute to a further exploration of the link between CSR and financial analysts.Design/methodology/approachThis study reviews and synthesises existing research on CSR and financial analysts. Based on the research question, “What is the relationship between CSR engagement and financial analysts’ metrics?,” the authors conduct a systematic literature review. The authors search three major databases and use an extensive search term to ensure exhaustive coverage of the field. The paper then systemises the current state of research and identifies knowledge gaps and potential directions for future research.FindingsThe review of existing research shows that several studies confirm a positive link between CSR performance and analyst coverage, suggesting that external monitoring through analysts incentivises companies to enhance their CSR engagement. Further, results indicate that a company’s involvement in “sin” industries is linked to lower analyst coverage. Besides, a higher level of CSR disclosure is positively associated with analyst forecast accuracy, thus indicating that the provision of CSR-related information is linked to an enhanced information environment. High levels of CSR performance are associated with more positive recommendations from analysts. However, recent surveys and interview studies on analysts’ perceptions of CSR fail to uniformly support an increasing interest in CSR.Research limitations/implicationsFor a better understanding of the link between CSR engagement and financial analysts, two fruitful directions for future research are observed. First, future research designs should clearly differentiate between CSR disclosure and CSR performance and take account of interdependencies between them. Second, studies should address behavioural insights into how analysts process information and the influence of individual analyst characteristics on the link between CSR engagement and an analyst’s assessment of a company.Originality/valueThis study is the first to review the literature on the relationship between CSR and financial analysts. The association between CSR and financial analysts is particularly interesting given the pivotal role financial analysts play as information intermediaries in financial markets. This study delivers an in-depth understanding of existing studies and their theoretical underpinnings. Based on the existing literature, this paper develops innovative directions for future research.

Power is a crucial concept for international relations scholars. Of particular importance for those interested in understanding foreign policy is knowing how power manifests as national capabilities. Understanding the relationship between power and capabilities allows for comparison and contrast of the various foreign policy tools leaders have at their disposal as they attempt to achieve their goals. Despite the importance of power, scholars still debate the best means for conceptualizing and operationalizing the concept. The all-encompassing nature of power makes it difficult to focus on a single characteristic. This article focuses on three main aspects of power: military, economic, and soft power. Each section gives an overview into the current state of research into the various aspects of power. The discussion on military power emphasizes operationalizing military might and issues with innovation. The section on economics focuses on economics as a source of power and a tool for coercion. Finally, the last section focuses on noncoercive aspects of power, better known as soft power. The article ends with some suggestions for future research.

The last 15 years has seen a tremendous growth in research on structural priming among second language (L2) speakers. Structural priming is the phenomenon whereby speakers are more likely to repeat a structure they have recently heard or produced. Research on L2 structural priming speaks to key issues regarding the underlying linguistic and cognitive mechanisms that support L2 acquisition and use, and the extent to which lexical and grammatical information are shared across an L2 speaker’s languages. As the number of researchers investigating L2 priming and its implications for L2 learning continues to grow, it is important to assess the current state of research in this area and establish directions for continued inquiry. The goal of the current review is to provide an overview of recent research on within-language L2 structural priming, with an eye towards the open questions that remain.

AbstractDue to the fast-paced nature of the software industry and the success of small agile projects, researchers and practitioners are interested in scaling agile processes to larger projects. Agile software development (ASD) has been growing in popularity for over two decades. With the success of small-scale agile transformation, organizations started to focus on scaling agile. There is a scarcity of literature in this field making it harder to find plausible evidence to identify the science behind large scale agile transformation. The objective of this paper is to present a better understanding of the current state of research in the field of scaled agile transformation and explore research gaps. This tertiary study identifies seven relevant peer reviewed studies and reports research findings and future research avenues.

PTSD can develop in the aftermath of traumatic incidents like combat, sexual abuse, or life threatening accidents. Unfortunately, there are still no biomarkers for this debilitating anxiety disorder in clinical use. Anyhow, there are numerous studies describing potential PTSD biomarkers, some of which might progress to the point of practical use in the future. Here, we outline and comment on some of the most prominent findings on potential imaging, psychological, endocrine, and molecular PTSD biomarkers and classify them into risk, disease, and therapy markers. Since for most of these potential PTSD markers a causal role in PTSD has been demonstrated or at least postulated, this review also gives an overview on the current state of research on PTSD pathobiology.

PurposeThe purpose of this paper is to provide a systematic review of articles on sport published in leading business studies journals within marketing, organisational studies and strategy.Design/methodology/approachBased on a review of 38 identified articles within the subfields of marketing, strategy and organisation studies published between 2000 and 2015, the articles’ topical, theoretical and methodological orientation within the studied subfields were analysed followed by a cross-subfield analysis.FindingsThe authors identify considerable differences in topical, theoretical and methodological orientation among the studied subfields’ associated articles. Overall, the authors also find that articles across all subfields tend to be focussed on contributing to mature theory, even though the subfield of marketing in particular exhibits contributions to nascent theory in contrast to organisation studies and strategy.Originality/valueThis paper contributes by illustrating the current state of research that is devoted or related to the phenomenon of sport within three subfields in business studies. Furthermore, the authors discuss the role played by leading business studies journalsvis-à-vissport sector-specific journals and offer avenues for future research.

Purpose-Mindfulness training is an emerging area in the field of research. There has been increased interest in this area on account of its usefulness to manage stress and prevent burnout. Yet there is limited research in the said area. Most research has either empirically examined the relationship of mindfulness training and burnout with other variables or it is a systematic review of literature in a sub-domain in that area. In this study, bibliometric analysis of Scopus listed publications is used to visualize the relationships between mindfulness training and burnout. Bibliographic coupling using VoSViewer was performed on the 87 Scopus publications obtained by using the keywords "mindfulness training" and "burnout". The application of bibliographic coupling resulted in 6 clusters. The themes of these 6 clusters as well as details of the top publications are examined in detail to understand the state of research in the area. Purpose: Mindfulness as a concept emerges from Buddhist principles. Mindfulness training is an emerging area of research, particularly in the context of its usefulness in managingstress and also in preventing burnout. In this research paper, the authors aim to systematically present the research in the field of mindfulness training and burnout with reference to most cited publications, countries, journals that are contributing the most to said area of research. Design/Methodology: This study analyses bibliometrically the links between mindfulness training and burnout for the listed publications in Scopus. For this research paper, the open software VOSviewer (van Eck and Waltman, 2010) was used to analyse the coupling of research papers in the area of mindfulness training and burnout to visualize the publications in this area in terms of the authorship. In this case, bibliographic coupling was carried out using VoSViewer with the sample of 87 Scopus publications obtained by using the keywords "mindfulness training" and "burnout". Findings/Conclusion: The bibliographic coupling analysis revealed six clusters. The overall structure of the cluster are: Cluster 2 ( 760), Cluster 1(462), Cluster 3 (300), Cluster 4 (296), Cluster 5 (159) and Cluster 6 (25). The critical papers that link the clusters are Roeser et al., (2013), Mackenzie , Poulin, Seidman-Carlson (2006a), Fortney et al., (2013, p.412), Dobkin, Hutchinson (2013), Moody et al., (2013) and O'Mahony et al., (2017). The application of bibliographic coupling resulted in 6 clusters. The themes of these 6 clusters are - Mindfulness Training Formats, Stress management & well-being, Mindfulness Training and work outcomes, Mindfulness training for Medical professionals and students and Facilitators of Mindfulness Training and end user benefits. Originality/Contribution/Value: This technique can be useful in understanding the evolution of research in the area. Given that this is an emerging area of research this paper can be useful to future researchers to visualize current research in the area and to identify areas of future research.

Health-related research is broad, diverse, and fragmented theoretically, methodologically, and across disciplines. The understanding and improvement of human health would be accelerated by establishing a universal and deep framework integrating varied undertakings. This framework is evolutionary theory, the most powerful explanatory system in the life sciences and the only framework that can unify knowledge in otherwise disparate fields of human research. Darwinian medicine has already made considerable progress in the practical understanding of human physiology and other areas informing medical care. Within evolutionary theory, life history theory in particular holds the promise of promoting understanding of variation in behavioral patterns related to health and why they vary consistent with environmental conditions. This chapter describes the current state of research exemplifying an evolutionary approach to health-related psychology and behavior and outlines directions for future research and intervention efforts.

There remains great interest in understanding the relationship between visual impairment (VI) and autism spectrum disorder (ASD) due to the extraordinarily high prevalence of ASD in blind and visually impaired children. The broad variability across individuals and assessment methodologies have made it difficult to understand whether autistic-like symptoms shown by some children with VI might reflect the influence of the visual deficit, or represent a primary neurodevelopmental condition that occurs independently of the VI itself. In the absence of a valid methodology adapted for the visually impaired population, diagnosis of ASD in children with VI is often based on non-objective clinical impression, with inconclusive prevalence data. In this review, we discuss the current state of knowledge and suggest directions for future research.

AbstractAlgorithmic decision-making is becoming increasingly common as a new source of advice in HR recruitment and HR development. While firms implement algorithmic decision-making to save costs as well as increase efficiency and objectivity, algorithmic decision-making might also lead to the unfair treatment of certain groups of people, implicit discrimination, and perceived unfairness. Current knowledge about the threats of unfairness and (implicit) discrimination by algorithmic decision-making is mostly unexplored in the human resource management context. Our goal is to clarify the current state of research related to HR recruitment and HR development, identify research gaps, and provide crucial future research directions. Based on a systematic review of 36 journal articles from 2014 to 2020, we present some applications of algorithmic decision-making and evaluate the possible pitfalls in these two essential HR functions. In doing this, we inform researchers and practitioners, offer important theoretical and practical implications, and suggest fruitful avenues for future research.
