Abstract
A numerical analysis of the micromechanical behaviour of a granular material is described using a new program MASOM based on Cundall's discrete element method. In the analysis the individual grains which make up the material are taken to be deformable 2D polygons of arbitrary size and shape. Contact forces between the grains are calculated according to Mindlin's solution for frictional contact between elastic bodies. The material in each grain is taken to be linear elastic but limited by the fracture strength of the material. Fracture is permitted along any one of a number of candidate fracture planes if an associated compressive load tending to split the gain reaches a critical level. Fragments of fractured grains are carried until they become too small to track using the explicit time integration algorithm used to advance the solution. The MASOM program is able to consider a number of different classes of elements and different types of contact between the various classes. Thus, in addition to the granular material the program can also model containers and loading devices. The program is used to simulate uniaxial and triaxial compression tests for geological materials. The results are shown to give results for stress‐strain and stress difference versus pressure which are in qualitative agreement with test data. The numerical results reveal a very complex micromechanical behaviour in granular materials, including highly variable and rather unstable load paths and a very inhomogeneous load distribution within a representative sample of the material. A video of the response of a typical frictional material to applied loads shows an interesting localized effect near sample boundaries involving crowding together of grains which cannot be observed using conventional static field plots.

Abstract
This chapter explores the emergence, growth, and current status of the sociology of sport in Canada. Such an endeavour includes acknowledging the work and efforts of Canadian scholars – whether Canadian by birth or naturalization or just as a result of their geographic location – who have contributed to the vibrant and robust academic discipline that is the sociology of sport in Canadian institutions coast-to-coast, and who have advanced the socio-cultural study of sport globally in substantial ways. This chapter does not provide an exhaustive description and analysis of the past and present states of the sociology of sport in Canada; in fact, it is important to note that an in-depth, critical and comprehensive analysis of our field in Canada is sorely lacking. Rather, this chapter aims to highlight the major historical drivers (both in terms of people and trends) of the field in Canada; provide a snapshot of the sociology of sport in Canada currently; and put forth some ideas as to future opportunities and challenges for the field in Canada.

Abstract
Sociology of sport in China has evolved from being an “exotic” subject to a localized subject over the past 35 years. It is closely associated with social changes, sports policy and athletic achievement of China. As a discipline of humanitarian and social sciences of sport, it is taught in virtually all universities with sports majors. There are about 500 scholars specializing in sport sociology in the country. Textbooks written by Chinese and foreign scholars are published. Academic papers on sport sociology are often published in the 15 accredited core sports journals. The most productive authors are from universities and the developed provinces and municipalities. The established research areas of sport sociology are extensive. These include national identity, athlete mobility, Olympic legacy, sport for all, sports industry issues, feminist studies, community sport, sport for the aged and disabled, etc. However, there are few studies with critical analysis and only a few in the areas of sport and religion, sport and race, and deviance in sport in China. Various kinds of financial support at different levels are available in the country. Empirical research is common with literature review, questionnaire, case study, and interview being the most frequently used methods. However, sport sociology is not considered as a major topic but as a research direction and it is not accepted widely by mainstream sociology. The future of sport sociology is promising, but not without challenges.

Abstract
Purpose
This paper provides a structured literature review of blockchain in accounting. The authors identify current trends, analyse and critique the key topics of research and discuss the future of this nascent field of inquiry.
Design/methodology/approach
This study’s analysis combined a structured literature review with citation analysis, topic modelling using a machine learning approach and a manual review of selected articles. The corpus comprised 153 academic papers from two ranked journal lists, the Association of Business Schools (ABS) and the Australian Business Deans Council (ABDC), and from the Social Science Research Network (SSRN). From this, the authors analysed and critiqued the current and future research trends in the four most predominant topics of research in blockchain for accounting.
Findings
Blockchain is not yet a mainstream accounting topic, and most of the current literature is normative. The four most commonly discussed areas of blockchain include the changing role of accountants; new challenges for auditors; opportunities and challenges of blockchain technology application; and the regulation of cryptoassets. While blockchain will likely be disruptive to accounting and auditing, there will still be a need for these roles. With the sheer volume of information that blockchain records, both professions may shift out of the back-office toward higher-profile advisory roles where accountants try to align competitive intelligence with business strategy, and auditors are called on ex ante to verify transactions and even whole ecosystems.
Research limitations/implications
The authors identify several challenges that will need to be examined in future research. Challenges include skilling up for a new paradigm, the logistical issues associated with managing and monitoring multiple parties all contributing to various public and private blockchains, and the pressing need for legal frameworks to regulate cryptoassets.
Practical implications
The possibilities that blockchain brings to information disclosure, fraud detection and overcoming the threat of shadow dealings in developing countries all contribute to the importance of further investigation into blockchain in accounting.
Originality/value
The authors’ structured literature review uniquely identifies critical research topics for developing future research directions related to blockchain in accounting.

Abstract
This chapter analyzes the development of the relationship between the social sciences and sport in Argentina – from its first steps, to the present, and to possible future issues. The description of Arbena (1999) from the last part of twentieth century about the situation of the social sciences and sport in Latin America in general and Argentina in particular could not be more precise:
Latin America has produced little scholarly analysis of sport and society, though information and insights are found in other types of writings, journalistic accounts such as club histories and popular biographies. What has been focused on soccer normally treats only the author’s own country, and is rarely available in English. Nowhere does a single author or academic group dominate. (Arbena, 2000, p. 548)

We also make reference to how the anthropologist Eduardo Archetti breaks that mold described by Arbena and how he becomes the undisputed referent in the study of the social sciences and sport in Argentina, and how his immense contribution is recognized in the region. We analyze the present status of this topic, its major changes, the development that the area has undergone so far, and the issues that are being studied today. Moreover, we mention the importance of sociology of sport in the academic field and its formalization. Finally, this chapter also considers possible future trends in the sociology of sport in Argentina.

Abstract
Martial arts and combat sports (MACS) are supported on ritualistic practices which often encompass hazing creating environments where catastrophic masculinities prevail. These forms of masculinities are strengthened inside MACS’ world resonating with masculinities spread out in wider society. We consider this to be the situation found in Brazilian society. With this study, our aim is to analyse how hazing practices in MACS contribute to the production of a socially legitimised catastrophic masculinity in Brazil. Catastrophic masculinity appears as a new concept proposed by Andrade (2022) to define a hegemonic, toxic and tragic form of masculinity spread in Brazil attached to a political power project. We carried out two qualitative empirical pieces of research that focused on three martial arts. These were ethnographic (participant-) observations of various events, training sessions, belt examination and competition and interviews with men participants. Supported by the presented data, we argue that hazing practices end up acting as a means of reproducing the catastrophic masculinity fighters perform in the dojo. They learn and resonate with a pedagogy that requires them to conform to and follow hierarchies through the repetition of the word ‘oss’ as a symbol of submission to arbitrariness. Hazing constitutes, instantiates and reproduces catastrophic masculinity and originates in the same (social) catastrophic masculinity.
