An accelerometer is a device that measures force due to gravity or a change in speed or direction of travel. This paper describes accelerometers and their application in other disciplines and, by way of an example, explores the utility of accelerometers for studying aggression. We end with a discussion of additional ways accelerometers might be used in group processes research.

We first review the use of accelerometers in other disciplines. We then present the results of four studies that demonstrate the use of accelerometers to measure aggression. Study 1 establishes the measure’s concurrent validity. Study 2 concerns its stability and representative reliability. Study 3 seeks to establish the measure’s predictive validity by associating it with an existing measure. Study 4 demonstrates the ability of accelerometers to address a sociological research question.

In Studies 1 and 2, we find that accelerometers can be used to differentiate between distinct levels of aggression. In Study 3, we find that men’s average peak acceleration correlates with a previously validated measure of aggression. Study 4 uses accelerometers to reproduce a well-established finding in the aggression literature.

We conclude that accelerometers are a flexible tool for group processes’ researchers and social scientists more broadly. Our findings should prove useful to social scientists interested in measuring aggression or in employing accelerometers in their work.

Although there has been much psychological research about children's sibling relations, it has been a neglected area of study in sociology (exceptions are Brannen et al., 2000; Kosonen, 1996; Mauthner, 2002). This paper, based on empirical research on siblings in Scotland, explores the nature of the generational power structure within families from children's perspectives. Childhood is a relational concept which forms part of the generational order. Alanen explains this as “a complex set of social processes through which people become (are constructed as) ‘children’ while other people become (are constructed as) ‘adults’” (2001, pp. 20, 21). Generational processes shape the nature of child-parent relations (Mayall, 2002). Alanen states that:one position (such as the parental position) cannot exist without the other (child) position; also what parenting is – that is, action in the position of a parent – is dependent on its relation to the action “performed” in the child position, and a change in one part is tied to change in the other (Alanen, 2001, p. 19).In other words, child-parent relations are based on the understanding that childhood is relational with parenthood (see also Mayall, 2002). Alanen (2001) argues that the social construction of childhood and adulthood involves a process, including the agency of both children and adults, which she refers to as a set of “practices”:It is through such practices that the two generational categories of children and adults are recurrently produced and therefore they stand in relations of connection and interaction, of interdependence (Alanen, 2001, p. 21).These practices of generationing may be “childing” practices through which people are constructed as children or “adulting” practices through which a distinct adult position is produced. The ways in which children in the present study talked about the differences between their relationships with their parents and their siblings indicated that there are a range of generationing practices that take place within families. They referred to particular kinds of behaviour that were acceptable to engage in with other children (in this case with their siblings) but not with their parents. Overwhelmingly the key issue which children highlighted as distinct between their relations with parents and siblings was the differential nature of power in these relationships. Whilst it is not surprising that children perceive the distribution of power to be more unequal between children and parents than between siblings, the aim of this paper is to explore the nature of this power and how it is experienced from children's point of view. In particular the paper discusses the ways in which children perceive child-parent relations compared with their sibling relationships in relation to the giving and receiving of power within the home.

This chapter explores how eight children from five Bolivian migrant families living in Madrid perceive their participation within their families. Children understand their participation as taking responsibility for domestic chores and taking care of younger siblings. Children's ideas of participation are associated with their school experience and are about simply having a voice in everyday mundane interactions with adults and peers.

Parents' cultural values, power and authority dominate decisions in the family. These children were born in Spain and practices in their family homes are influenced by their parent's strong cultural ties with Bolivia. The data collected show that the lives of these children and their views of participation need to be understood beyond the binary of the Global North and Global South (Twum-Danso Imoh et al., 2019).

The research employed the ‘routes of participation’, a playful and creative research method that aimed to empower children to explore their ‘interdependent agency’ (Abebe, 2019) and the meaning of participation within the context of their family lives. We conclude that any successful intervention with children needs to understand the meaning of what children say in relation to the various situations in which they live. Listening to children's voices and paying attention to the language that they use in their everyday lives should continue to be the basis of child-centred research and child-centred practice. The chapter encourages to reflect on the value of culturally grounded playful activities to understand children's agentic experiences and their contribution that they can make to their own lives.

Purpose: Analysis and systematisation of global trends in the transformation of DSSs from the standpoint of solving their global and local problems and determining the central axioms of setting up and supporting business processes in DSSs.

Need of the Study: Decision Support Systems (DSSs) are the basis of doing business in an enterprise by automating business processes, keeping accounting and reducing various risks associated with complexity, labour-intensiveness, slow execution time and, therefore, potential loss of profit. In recent decades, the rapid development of DSSs has led to the emergence of complex enterprise information system architectures. At the same time, many local business processes are not implemented or are partially implemented. In Ukraine, such techniques include VAT accounting.

Methodology: The study is based on the literature analysis, Internet resources and practical experience obtained during the SAP ERP system implementation projects. Particular attention is paid to developing information systems architecture to solve the problems enterprises face during their growth. Thanks to the analysis of the example of the realisation of the Internet sales process and the induction method, the axioms of automation of business processes in accounting systems were formed.

Findings: Regardless of the qualitative and quantitative transformation, modern DSSs still cannot solve all the enterprise’s problems, mainly due to the use of paper documents and the diversity of national legislation. By the example of the SAP ERP system, the optimal implementation of the business process of VAT liabilities was proposed by Ukrainian legislation for sales below cost price.

Practical Implications: Compliance with the established axioms of automation of business processes will reduce the cost of resources for their implementation, maintenance and correction of potential errors and, therefore, will provide an opportunity to process more transactions. Implementing the proposed algorithm for calculating VAT liabilities in SAP ERP for sales below the cost price will simplify the existing process and enable the fulfilment of other requirements within the framework of current legislation.

Purpose – The broader aim of this research is twofold. First, we aim to better understand how the business computer was conceptualized and used within U.S. industry. Second, this research investigates the role of social factors such as relational structure, institutional entrepreneurs, and position in the formation of conceptualizations of new technologies.

Design/methodological/approach – This paper is theoretically motivated in the sense that it responds to the lack of attention to the failure of institutional entrepreneurs to change belief systems. Through detailed archival, network, and descriptive statistical analysis, the paper shows how the failed institutional entrepreneur fits conventional explanations for success. The paper then analyzes two matched cases, comparing the insurance industry's rejection of the institutional entrepreneur with manufacturing's acceptance, in order to identify what is missing in current explanations of institutional entrepreneurs.

Findings – Our analysis reveals that the role of the audience structure in interpreting the institutional entrepreneur's message influences the change outcome. In our case, the institutional entrepreneur's view of the computer as a brain that supported decision-oriented applications did not fit with views of the insurance groups who had centralized authority over interpreting the computer. Because manufacturing had less centralized control in its discourse around the computer, there were fewer constraints on assimilation, allowing the entrepreneur's views to resonate with some of the occupational groups.

Research limitations/implications – This paper develops a theoretical approach to institutional entrepreneurship that situates the entrepreneurial efforts of individual actors within a system characterized by the structure of its audience and subject to distinct historical macro-structural processes that present significant obstacles to the realization of their entrepreneurial projects.

It is unclear from Canadian case law what the appropriate legal standards of care and regulation should be in athlete injury cases. This chapter provides an overview of existing legal standards and explores the question of participant liability in sport, especially ice hockey. It reviews the applicability of tort law, including both intentional torts and unintentional torts, and considers the applicability and impact of the notion of ‘volenti non fit injuria’ (or voluntary assumption of risk).

The chapter is based on a review of Canadian case law.

Canadian courts have adopted varying standards whereby it is seemingly easier to prove negligence in certain provinces than others. We discuss the implications of these conflicting jurisdictional standards and the need for clearer and more consistent legal guidelines. Further, we show why appropriate legal standards should extend beyond purely objective and legalistic interpretations to more subjective and sociological factors that place sports violence and sports injury in social context.
