Variation Iteration Method

PurposeIn this article, the authors consider the following nonlinear singular boundary value problem (SBVP) known as Lane–Emden equations, −u″(t)-(α/t) u′(t) = g(t, u), 0 < t < 1 where α ≥ 1 subject to two-point and three-point boundary conditions. The authors propose to develop a novel method to solve the class of Lane–Emden equations.Design/methodology/approachThe authors improve the modified variation iteration method (VIM) proposed in [JAAC, 9(4) 1242–1260 (2019)], which greatly accelerates the convergence and reduces the computational task.FindingsThe findings revealed that either exact or highly accurate approximate solutions of Lane–Emden equations can be computed with the proposed method.Originality/valueNovel modification is made in the VIM that provides either exact or highly accurate approximate solutions of Lane-Emden equations, which does not exist in the literature.

Purpose – The purpose of this paper is to explore Chinese food safety issues by analysing select incidents within he Chinese agricultural marketing system. Design/methodology/approach – A marketing utility framework is utilized to discuss some of the major food safety incidents in China and potential solutions are explored. Findings – The paper finds that food safety issues arise from problems of asymmetric information which leads to the profit seeking behaviour of agents distorting rather than enhancing the creation of one of the four types or marketing utility (time, form, place and possession). Additionally, structural causes found within the Chinese food marketing system have contributed to the food safety problems. Research limitations/implications – This is not an empirical research with numerical data. Originality/value – This study is one of the first to address Chinese food safety problems from an agricultural marketing utility perspective. Key anecdotes are used to support the claims made in this study.

Purpose – This study aims to ascertain the trends and changes of how academic libraries market and deliver information literacy (IL) on the web. Design/methodology/approach – The author compares the findings from two separate studies that scanned the Web sites for IL-related activities in 2009 and 2012, respectively. Findings – Academic libraries intensified their efforts to promote and deliver IL on the web between 2009 and 2012. There was a significant increase in IL-related activities on the web in the three-year period. Practical implications – The findings describe the status quo and changes in IL-related activities on the libraries’ Web sites. This information may help librarians to know what they have been doing and if there is space for improvement. Originality/value – This is the only study that spans three years in measuring the progress librarians made in marketing and delivering IL on the Web.

Purpose The paper aims to rediscover the subtle heart and discuss its importance in relation to conversations regarding sustainability. Design/methodology/approach Based on the imaginal approach of the author’s doctoral research, this paper is informed by the discourse of transpersonal psychology, attempting to open a space through which it becomes possible to perceive the heart differently. Findings This paper discusses the idea that knowledge as generated through the heart has been rendered subservient to knowledge generated through the mind/brain through a dominant/medical narrative (Bound Alberti, 2012). This means that the heart’s wisdom and the heart’s benevolent qualities cannot gain traction at the level at which decisions are made in society. Research limitations/implications While the heart is not unproblematic, and can carry notions of moral superiority, this paper is written as an appeal to create safe enough spaces to bring the heart back into conversation at the level of political discourse. Practical implications This paper suggests that it is the approach of the heart, the qualities and characteristics that the heart embodies, and the different way of being in the world that the heart makes possible, which could play an important role in guiding us towards a more sustainable world. When taken seriously, the heart offers a way of engaging with, and thinking about, ideas of relationship, wholeness and interconnection – all of which have been identified as important by numerous scholars in relation to engaging with global challenges (de Witt, 2016). Social implications This paper suggests that it is the approach of the heart and the different way of being in the world that the heart makes possible, which could play an important role in guiding humanity towards a more sustainable world. Originality/value Since the late 1900s, scholars have been calling for creative thinking in relation to engaging with the myriad of issues facing our planet, and this paper is written as a response to that call – creating a platform for the heart to speak and making a case for its importance in conversations relating to sustainability.

Purpose This paper aims to effectively achieve endmembers and relative abundances simultaneously in hyperspectral image unmixing yield. Hyperspectral unmixing, which is an important step before image classification and recognition, is a challenging issue because of the limited resolution of image sensors and the complex diversity of nature. Unmixing can be performed using different methods, such as blind source separation and semi-supervised spectral unmixing. However, these methods have disadvantages such as inaccurate results or the need for the spectral library to be known a priori. Design/methodology/approach This paper proposes a novel method for hyperspectral unmixing called fuzzy c-means unmixing, which achieves endmembers and relative abundance through repeated iteration analysis at the same time. Findings Experimental results demonstrate that the proposed method can effectively implement hyperspectral unmixing with high accuracy. Originality/value The proposed method present an effective framework for the challenging field of hyperspectral image unmixing.

Purpose The purpose of this paper is to assess the recent emergence of contemporary art in Asia from a macro, sociocultural perspective. Design/methodology/approach This commentary is based on secondary research and recent visits to contemporary art centres in major cities across Asia. Findings The author argues that contemporary art in Asia emerges by extension of the Western contemporary art world and suggests that more must be done if Asia is to create a contemporary art world that is both internationally recognised and distinct from its Western precedent. Originality/value This commentary debunks the hyperbole surrounding contemporary art in Asia as a regional phenomenon and provides a critical examination of the global (power) dynamics at play.

Purpose This paper aims to examine whether agency costs predict disciplinary takeover likelihood for the UK listed companies between 1986 and 2015. Design/methodology/approach Using survival analysis, the approach is to identify candidates for disciplinary takeover on the basis of Tobin’s Q (TQ), which is consistent with the approach advocated by Manne (1965). This study then examines how indicators of agency costs affect takeover likelihood within the set of disciplinary candidates. Findings This paper provides evidence of the effectiveness of TQ, rather than excess return, in identifying disciplinary takeover candidates. Takeover hazard for disciplinary candidates is higher for companies with higher levels of asset utilization and sales growth in particular. Companies with stronger agency problems are relatively less susceptible to disciplinary takeover. Practical implications Given the UK context of the study, where anti-takeover provisions are disallowed and when compared to findings of US studies, the results imply some support for the effectiveness of an open merger policy. Originality/value While the connection between takeover likelihood and the market for corporate control has been made in previous studies, the study adopts a more explicit agency theory framework than previous studies of takeover likelihood. A key component of the contribution follows from differentiating candidates for disciplinary takeovers from other forms of mergers and acquisitions.

Purpose A review of literature revealed that many publications on efforts at combatting money laundering focus on two frameworks, namely, legal/legislative and institutional, while overlooking the third and equally important framework – the “regulatory/ supervisory framework.” This paper aims to eradicate the dearth in literature with regards to this third and seldom acknowledged framework and it aims at filling that gap. Design/methodology/approach The analysis took the form of a desk study, which distinguished the three frameworks for combatting money laundering and provided a comprehensive list of the main actors in each regime within the Nigerian legal context. The Money Laundering (Prevention and Prohibition) Act, 2016 was examined in detail. Findings Three categories of regulators were identified and discussed in this paper: the supervisory bodies that regulate the activities of financial institutions, namely, Central Bank of Nigeria, Securities and Exchange Commission and Nigerian Insurance Commission; The Bureau for Money Laundering Control which supervises – designated non-financial institutions and businesses; the Attorney General of the Federation; and (Self-Regulatory Organizations. The Attorney General of the Federation was identified as the prime regulator within the context of the 2016 Act. Suggestions on how the regulators could make the most of their roles were made in the concluding part. Research limitations/implications This paper only considered the Nigerian legal context and only the extant law – the Money Laundering (Prevention and Prohibition) Act, 2016 was critically examined. Originality/value The findings in this paper and the writing approach are original.

Purpose This paper aims to ask whether the implementation of the expanded auditor’s report, which included a requirement to disclose key audit matters (KAMs) in Thailand since 2016, has improved audit quality. Design/methodology/approach To answer this question, the authors examined audit quality two years before and two years after its adoption by analysing 1,519 firm-year observations obtained from 312 companies. The authors applied logistic regression analyses to the firm-year observations. Findings The authors found some weak evidence that KAMs disclosure improved audit quality because of auditors putting more effort into their audits and audits being performed thoroughly after the implementation of KAMs. Interestingly, the number of disclosed KAMs and the most common types of disclosed KAMs are not associated with audit quality. Only disclosed KAMs related to acquisitions are more informative because the presence of this type of disclosed KAMs signals the greater likelihood of financial restatements being made in a later year. Originality/value Unlike previous studies on the impact of KAMs disclosure on audit quality, which used discretionary accruals as proxy for audit quality, this study used the occurrence of financial restatements.

Purpose – The purpose of this study is to understand how board composition and independent non-executive director (INED) disclosures have changed in light of the global financial crisis (GFC) from an accountability perspective. Design/methodology/approach – Content analysis techniques were undertaken on a random sample of 75 publicly listed companies across two time periods, 2005 and 2010. Findings – The findings highlighted increased INED board membership and increased skill and experience disclosure across all board positions, with the most significant increase being the INED position. The results support the notion that firms are attempting to restore their accountability relationships post-GFC through more transparent mechanisms of governance. However, concerns are also raised in the way individual companies are meeting the ASX Corporate Governance independence requirements. Research limitations/implications – The results raise questions as to whether firms have implemented these changes to ensure effective governance and accountability responsibilities, or simply to give the appearance of good governance. Originality/value – Little attention has been given in the literature to the characteristics of INEDs and whether board changes have been made in the wake of corporate and financial crises. The findings from this study contribute to an understanding of board composition and disclosures pre- and post-GFC.

Purpose This study aims to empirically investigate the effects of labor displacement on US management consulting (MC) firms. Design/methodology/approach This paper leverages standard linear regressions to identify and discuss correlations between progresses made in terms of labor displacement and the evolution of MC firms performance indicators. Findings In the context of US MC practices, the study shows that for every percent of work displaced, production costs are reduced by $3.7/h on average. It also highlights that as prices also go down by $3.3/h on average per percent of work displaced, off/near-shoring increases MC practices profitability. Displacing labor is yet a transformation that occurs mainly in very large firms (i.e. more than 1,000+ employees) and its full potential takes more than 4–5 years to realize. Originality/value This study provides new empirical benchmarks of the effect of labor displacement on MC firms. This study shows how long off/near-shoring takes to reach its full maturity.
