PurposeThe aim of this article was to analyze how the presence of the elements that constitute organizational links are related to sensemaking in a cooperative system of medical work.Design/methodology/approachA content analysis was conducted following interviews with the managers of the cooperative, which is a member of the Brazilian cooperative system and one of the largest in the world. This analysis enabled the systematization of the categories that were identified through the coding of responses, aided by Atlas.ti 8.0 software.FindingsAfter the analysis, it was possible to resize the constitutive elements identified in the specialized literature into three categories: identification, cooperation and recognition. The proposed resizing does not preclude the presence of the constitutive elements identified in the analysis, but it evidences the presence of these elements in a contextualized manner, suggesting a model of an organic organizational link that is dependent on the relationship between subject–object (organization), in which the different perceptions of meanings affect identification, and this can strengthen or weaken the link in a constant process of resignification.Originality/valueWith regard to its theoretical relevance, the work helps to bring concepts related to organizational links and sensemaking closer together as a process in the realm of intersubjectivity. This provides evidence of the presence of constituent elements of ties in a contextualized manner, demonstrating that the interpretation of managers aids sensemaking in a process of circularity and resignification.

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 This paper aims at understanding the dynamics underlying toleration as a complex social phenomenon and its pattern on Facebook during the June 30th revolution in Egypt. Thanks to the huge advances in ICT, internet-mediated research (IMR) has become one of the most prominent research methodologies in social sciences. Discussions on social network sites cannot be neglected in studying the dynamics complex and emerging social phenomena such as changes in public opinion, culture, attitudes and virtues. Design/methodology/approach To fulfill this aim, the researchers used web content analysis as a method inside IMR paradigm to analyze the discussions on Tamarrod’s Facebook page in the period from June 30th to July 5th and to examine the emerging overall pattern of toleration. Findings The results show indications that toleration is inherent in the Egyptian culture, and that the Egyptian society still keeps its reputation as a highly tolerant society, even in crises periods where tensions are witnessed everywhere. Moreover, the results also show that the web content analysis process proposed in this study is highly reliable and valid. Originality/value The importance of the study lies in introducing a computational and empirical approach to analyze web content in a semi-automated way and proving its validity and reliability to study social phenomena such as toleration.

Purpose The prevalence of domestic violence in Nigeria may be described as epidemic. To address this scourge, several pieces of legislation have been enacted in the past decade at state and federal levels in Nigeria. The purpose of this study is to evaluate the emerging legislation on domestic violence. This paper thus examines the contents of these laws in a bid to determine the potential of these laws to prevent domestic violence, deter perpetrators from further incidents, punish perpetrators, compensate survivors and provide them with the necessary interventions for their rehabilitation. Design/methodology/approach The approach adopted is a content analysis of the provisions of the legislation, using salient parameters that have been drawn from documented best practices, specifically the key components for framing of domestic violence legislation around the world. Findings The author finds that while there is significant attempt in extant legislation to ensure that women are protected within domestic relationships, there are still gaps. Further, the protections are uneven across the states. In addition, there are systemic and contextual challenges that hamper the effectiveness of existing legislation in Nigeria in providing the necessary protections to women. Originality/value This study analyses the provisions of some of the legislation currently in place to protect persons from domestic violence. The impact, potential effect and overall utility of these pieces of legislation continue to require examination.

Purpose The purpose of this paper is to provide the current state of knowledge about the Flash Crash. It has been one of the remarkable events of the decade and its causes are still a matter of debate. Design/methodology/approach This paper reviews the literature since the early days to most recent findings, and critically compares the most important hypotheses about the possible causes of the crisis. Findings Among the causes of the Flash Crash, the literature has propsed the following: a large selling program triggering the sales wave, small but not negligible delays suffered by the exchange computers, the micro-structure of the financial markets, the price fall leading to margin cover and forced sales, some types of feedback loops leading to downward price spiral, stop-loss orders coupled with scarce liquidity that triggered price reduction. On its turn leading to further stop-loss activation, the use of Intermarket Sweep Orders, that is, orders that sacrificed search for the best price to speed of execution, and dumb algorithms. Originality/value The results of the previous section are condensed in a set of policy implications and recommendations.

Purpose Business Process Management (BPM) is key for successful organisational management. However, BPM techniques are often criticized for their inability to deal with continuous and significant change and uncertainty. Following recent calls to make BPM more agile and flexible towards change, this study presents the results of a systematic literature review (SLR) of agile concepts in BPM. Analysing and synthesising previous works and drawing on agility research in the field of IS, this paper introduces a framework for agile BPM. Integrating different components that define agility in the context of BPM, this framework offers a number of important implications. On the theoretical side, the authors argue that the concept of agile BPM departs in some important ways from traditional BPM research. This, in turn, points to various opportunities for future research. On the practical side, the authors suggest that emerging technologies, such as process mining, embody important features that help organisations to be more responsive to change. The paper aims to discuss these issues. Design/methodology/approach To assess the state of the art of agility in the BPM research, the authors conducted an SLR. More specifically, the authors drew on the approach of vom Brocke et al. (2009, 2015), which consists of five steps: defining the scope of the review; conceptualising the topic; searching for literature; analysing and synthesising literature; and developing a research agenda. Findings This study presents the results of a systematic review of agile concepts in BPM. This study then proposes a resulting research framework that can be used to strengthen the concept of agile BPM and provides an agenda for research in this rapidly growing and increasingly necessary area of BPM. Originality/value In this paper, the authors establish a shared understanding of agile BPM and develop an agile BPM framework that represents the current state as well as implications for research and practice in agile BPM.

Purpose The purpose of this paper is to discuss the current state-of-the-art in additive manufacturing, more commonly known as 3D printing, from the business perspectives. The primary drivers behind the development of the associated technologies are considered along with features that limit growth. Design/methodology/approach The approach is a personal perspective, based on approximately 25-years study of the development of the associated technologies and applications. Findings The discussion has found that the technology is still growing healthily, but with an understanding that there are numerous application areas that should be considered separately. Some areas are significantly more mature than others and success in some areas does not guarantee success in others. Originality/value This viewpoint has been prepared for the current state-of-the-art and can be compared with earlier viewpoints to see how things may have changed in the past. This should be of value to those interested to explore how the technology has developed in recent times and how it may move into the future.

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.

Purpose Fog computing is a new field of research and has emerged as a complement to the cloud which can mitigate the problems inherent to the cloud computing model such as unreliable latency, bandwidth constraints, security and mobility. This paper aims to provide detailed survey in the field of fog computing covering the current state-of-the-art in fog computing. Design/methodology/approach Cloud was developed for IT and not for Internet of Things (IoT); as a result, cloud is unable to meet the computing, storage, control and networking demands of the IoT applications. Fog is a companion for the cloud and aims to extend the cloud capabilities to the edge of the network. Findings Lack of survey papers in the area of fog computing was an important motivational factor for writing this paper. This paper highlights the capabilities of the fog computing and where it fits in between IoT and cloud. This paper has also presented architecture of the fog computing model and its characteristics. Finally, the challenges in the field of fog computing have been discussed in detail which need to be overcome to realize its full potential. Originality/value This paper presents the current state-of-the-art in fog computing. Lack of such papers increases the importance of this paper. It also includes challenges and opportunities in the fog computing and various possible solutions to overcome those challenges.
