Purpose The purpose of this paper is to present an overview of the flash crash, and explain why and how it happened. Design/methodology/approach The author summarizes several studies suggesting various perspectives on the flash crash and its causes. Furthermore, the author highlights recently proposed and introduced improvements and regulations to reduce the risk of having similar market collapses in the future. Findings It is an overview paper that highlights the state of the art on the subject. Research limitations/implications Paper does not report any research findings of the author. Practical implications High-frequency trading (HFT) along with its pros and cons is the new normal for most of the current electronic trading activity in the markets. It is well recognized by the experts that HFT may have its important shortcomings whenever the rules and regulations are not up to date to match the technological progress offering faster computational and execution capabilities. Social implications HFT has created a societal discussion about its benefits and potential deficiencies as the common practice for trading due to potentially unequal access to market data by various categories of participants. Such arguments help the regulators to develop improvements to reduce the market risk and nurture more robust and fair markets for all. Originality/value The paper has a tutorial value and summarizes the current state of HFT. The readers of more interest are guided to the most relevant literature for further reading.

The Subject

Purpose The purpose of this paper is to explore the current state of popular modern methods of construction (MMC) and pre-manufactured construction in the construction industry and propose a framework for future implications for practice and future research. Design/methodology/approach This technical paper is based on a narrative review of the extant literature on the subject. First, the Scopus search engine was used to retrieve relevant papers on MMC, offsite and pre-manufactured construction. Second, institutional literature such as reports by industry professional and trade bodies, literature from leading technology firms and contractors with experience of MMC were extracted. These two strands of literature were synthesised and a comprehensive discussion on the topic was provided. Findings Results show that journal publications on MMC and pre-manufactured construction have increased in the past decade. The paper found significant advances in the development of premanufactured and offsite construction approaches with many benefits. Offsite and pre-manufactured construction are viable and sustainable systems currently suitable for wider adoption as the mainstream construction method. Research limitations/implications This technical paper based on an integrative review of relevant literature could have benefitted from interviews of professionals with experience of offsite and pre-manufacture techniques and from wider availability of current academic publications on the subject. Validation of the framework has not been undertaken. Originality/value Not much-published work has been undertaken on the current state of development globally and the viability of these construction approaches. This paper evaluates evidence from academic and industry sources to address this gap. A framework has been developed which can help the industry’s industrialisation drive.

Purpose Despite the potential of SMEs in economic development, their activities have remained largely unsustainable in Nigeria. These enterprises are constrained by a number of challenges- high cost of production, poor power supply, high infrastructural deficit etc. which have made there operations largely unproductive. The purpose of this paper is to examine the effects of production subcontracting forms on the sustenance of small and medium enterprises as a panacea for achieving the targets of goal 8 of sustainable development goals (SDGs) in Enugu State, Nigeria. Design/methodology/approach The paper adopted a number of methods comprising of field observations, a reference to relevant literature and a questionnaire survey of 96 SMEs. The paper also adopted a quantitative approach comprising of simple descriptive statistics of mean and standard deviation as well as regression analysis to analyze the data. Findings This paper found that the three forms of production subcontracting (supplier, specialized and capacity subcontracting) identified in the paper were used by SMEs to achieve sustenance (cost reduction, risk reduction and access to resources) in their operations. The paper suggests that the sustenance of SMEs through the utilisation of the different forms of subcontracting can become a strategy towards achieving the targets of SDG 8 in Nigeria. Practical implications This paper has shown that the prevalent high cost of production and ever-increasing production risks, which are the common features of SMEs in Nigeria, can be mitigated through the various forms of production subcontracting analysed in this paper. SMEs, through seminars, workshops, entrepreneurship and business fares, can be encouraged to take up this strategy, considering its ability to address their various operational bottlenecks. Originality/value This study adds to the limited available evidence concerning the effects of subcontracting forms on the sustenance of SMEs in Nigeria. This study is the first to consider subcontracting forms and how they have led to sustenance SMEs in Nigeria.

PurposeThis study updates and extends the current work on the issue of accuracy of property valuation. The paper investigates the factors that contribute to property valuation inaccuracy and examines different strategies to achieve greater accuracy in practice.Design/methodology/approachAn online questionnaire was designed and administered on the Australian Property Institute (API) registered valuers, attempting to examine their perceptions on the current state of valuation accuracy in Australia. The variables/statements from responses are ranked overall and compared for differences by the characteristics of respondents.FindingsUsing mean rating point, the survey ranked three factors; inexperience valuers, the selection, interpretation and use of comparable evidence in property valuation exercise and the complexity of the subject property in terms of design, age, material specification and state of repairs as the most significant factors currently affecting valuation inaccuracy. The results of a Chi-square test did not, however, show a significant statistical relationship between respondents' profile and the perception on the comparative importance of the factors identified. Except for valuers' age and inexperience valuers and valuers' educational qualification and inexperience valuers and the selection, interpretation and use of comparable evidence in property valuation exercise. Also, the three highly ranked strategies for reducing the level of inaccuracy are: developing a global mindset, use of advanced methodology and training valuers on market forecasting skills.Practical implicationsIn order for valuers to provide state-of-the-art service to the public and to remain relevant, there is a need to accurately and reliably estimate valuation figures. Hence, the strategies highlighted in this study could be considered in a bid to reduce property valuation inaccuracy in practice.Originality/valueThis study provides an updated overview of the issue of property valuation inaccuracy in the Australia valuation practice and examines the strategies to reduce it.

Purpose The paper is intended as an extension of the literature dealing with the Islamic accounting standards issued by the Accounting Auditing Organization for Islamic Financial Institutions (AAOIFI) and still not adopted in Tunisia. Its major aim is to investigate the Tunisian accountants’ basic knowledge and perceptions of Islamic accounting. The study has been designed for the sake of the Tunisian accountants’ predisposition to adhere to the AAOIFI standards, as a population directly concerned by an eventual adoption of such standards. Design/methodology/approach The paper opted for an exploratory study using a questionnaire survey based on the relevant literature. The questionnaire has included items pertaining to demographic areas, information sources, basic knowledge, key differences, valuation concepts, obstacles and advantages, educational and training needs regarding Islamic accounting. The conducted study has involved data collected from the part of 200 practitioners across a number of organizations and audit firms, sited at different regions and locations of the country, employing accounting graduates. Findings The reached findings suggest that even though Tunisian practitioners are not well aware of most of the AAOIFI standards’ pertaining topics, proponents of stand-alone AAOIFI standards, apart from IFRS, appear to outnumber its opponents. In this context, lack of training programs arranged by professional bodies is considered as the most serious impediment facing the implementation of the standards. Research limitations/implications In addition to the usual limitations associated with any survey research (particularly non-response bias and desirability bias), there, also, lies a sample related limitation, as the sample turns out to involve, essentially the private/corporate sector. Pertinent organizations, as the IFI’s, appear to be not well represented in the sample. Practical implications The results reached through this study would have some implications on the regulatory bodies, academicians and professionals. Thus, for the AAOIFI standards to be successfully implemented in Tunisia, entirety of concerned parties should take part in improving and consolidating the situation. Social implications Ultimately, studying differences in the views of jurisdictions, either those who have adopted the AAOIFI standards or those who have not, might provide certain guidelines to standard setters for potential revisions. Originality/value Few short articles have previously exanimate the perceptions and knowledge of accounting professionals on Islamic accounting issues, there is a scarcity of research regarding the subject. To the author’s knowledge, this paper is one of the rare studies of Islamic accounting in Tunisia.

PurposeThe purpose of the paper is to explore the meaning of HR analytics and introduce the HR analytics cycle as a proactive and systematic process for ethically gathering, analyzing, communicating and using evidence-based HR research and analytical insights to help organizations achieve their strategic objectives.Design/methodology/approachConceptual review of the current state and meaning of HR analytics. Using the HR analytics cycle as a framework, the authors describe a seven-step process for building evidence-based and ethical HR analytics capabilities.FindingsHR analytics is a nascent discipline and there are a multitude of monikers and competing definitions. With few exceptions, these definitions lack emphasis on evidence-based practice (i.e. the use of scientific research findings in adopting HR practices), ethical practice (i.e. ethically gathering and using HR data and insights) and the role of broader HR research and experimentation. More importantly, there are no practical models or frameworks available to help guide HR leaders and practitioners in doing HR analytics work.Practical implicationsThe HR analytics cycle encompasses a broader range of HR analytics practices and data sources including HR research and experimentation in the context of social, behavioral and organizational science.Originality/valueThis paper introduces the HR analytics cycle as a practical seven-step approach for making HR analytics work in organizations.

PurposeScholars are increasingly acknowledging the importance of conversations in the management of complex projects. Defining dialectics as “the art of purposeful conversation”, this paper aims to rationalise the somewhat disorganised field of dialectics by developing a categoreal scheme.Design/methodology/approachThe authors refer to the current state of research into the conversational aspects of complex projects, and examine the historical development of, and philosophical and scholarly commentary on, the dialectical method.FindingsThe categories the authors propose are the Socratic, Conversational, Fichtean and Peircean. They differ in relation to the subject matter of the dialectic; their vulnerability to environmental influences; the degree of structure they require for optimal performance; and the situations in which they might most profitably be applied.Research limitations/implicationsA single categoreal scheme is rarely the last word, and the authors invite other scholars to explore the field in a similar way.Practical implicationsThe scheme proposed here is intended to enhance the project manager's approach to conversations, by referring to the specific virtues and limitations of each of the categories.Social implicationsThe informed use of dialectics may help to ameliorate the significant damage done to organisations and economies around the world by failed and underperforming projects.Originality/valueThe authors present the first categorisation of the field, with the aim of equipping the practitioner to think about dialectical approaches in a more systematic way.
