The idea of implementing supply chain management (SCM) principles for the construction industry was embraced by construction stakeholders to enhance the sector's performance. The analysis from the literature revealed that the implementation of SCM in the construction industry enhances the industry's value in terms of cost-saving, time savings, material management, risk management and others. The construction supply chain (CSC) can be managed using the pull or push system. This chapter also discusses the origin and proliferation of SCM into the construction industry. The chapter revealed that the concept of SCM has passed through five different eras: the creation era, the use of ERP, globalisation stage, specialisation stage and electronic stage. The findings from the literature revealed that we are presently in the fourth industrial revolution (4IR) era. At this stage, the SCM witnesses the adoption of technologies and principles driven by the 4IR. This chapter also revealed that the practice of SCM in the construction industry is centred around integration, collaboration, communication and the structure of the supply chain (SC). The forms and challenges hindering the adoption of these practices were also discussed extensively in this chapter.

This chapter presented the model for the effective practice of construction supply chain management (CSCM) in the fourth industrial revolution (4IR) era. The model was developed after discovering that the failure of adopting the 4IR component has hindered the synchronisation of construction supply chain (CSC) activities. While some stakeholders are willing to manage their CSC under the 4IR era, most have no clue how to go about it. Most stakeholders are familiar with an existing practice built around collaboration, integration, supply chain structure and trust. This chapter bridges the gap by introducing organisational culture and 4IR components for modelling the CSCM in the 4IR era. The model was backed and grounded with a robust theoretical framework. The theories include social identity theory, change theory and resource-based view theory. It was discovered that the organisational culture adopted by construction stakeholders determines their willingness to embrace the 4IR component for the management of CSC. The 4IR components were divided into smart management, virtualisation and cyber-physical systems. The chapter recommended that the practice of SCM in the Nigerian construction industry should be modelled around the six constructs that were used in developing the model for this study.

In response to widespread concerns about health and fairness within elite sport, the World Anti-Doping Agency (WADA) was established as an organization to tackle the use of performance enhancing drugs in sport. Whilst significant efforts have been made to regulate performance enhancement in the context of elite sport, the use of prohibited substances continues to persist. Doping rules are now potentially applicable across sporting levels, not just within elite sport. The WADA has further formalized its jurisdiction in recreational sport by defining the term ‘recreational athlete’ for the purposes of their regulation within and by the 2021 WADA Code. The extension of Anti-Doping Policy into recreational sport broadens the scope of anti-doping's regulatory framework but is consistent in its health protection rationale, and its attempt to preserve sporting integrity. There are, however, a number of ethical concerns associated with the application of Anti-Doping Policy within recreational sport. Anti-doping policy was originally designed exclusively for elite athletes and although amendments have been made within the revised 2021 World Anti-Doping Code, it is unclear whether this extension is justifiable or operationalizable on a global scale. This chapter pays particular attention to the 2021 WADA Code revisions and draws attention to the role of anti-doping policy within recreational sport. Here we raise some ethical concerns associated with the 2021 WADA Code and critically examine the implications for recreational athletes.

This chapter introduces the main aims and ambition with the anthology, which is to bring together research from diverse perspectives on doping and Image and Performance Enhancing Drug (IPED) use. The chapter highlights existing but often backgrounded links between sport and fitness doping research and present a re-reading of the cultural history of doping through which simplistic divisions, such as that between sport and fitness, are deconstructed. Further, by unbinding the hegemonic divide between sports doping and fitness doping, new insights (and themes) concerning anti-doping, health and risk, new emerging doping spaces and the gendering of this field of research are brought to the fore. These themes are then used as point of departure when introducing the different chapters and scholars that contribute to the volume at hand.

This chapter uses a dataset of heights calculated from the femurs of skeletal remains to explore the development of stature in England across the last two millennia. We find that heights increased during the Roman period and then steadily fell during the “Dark Ages” in the early medieval period. At the turn of the first millennium, heights grew rapidly, but after 1200 they started to decline coinciding with the agricultural depression, the Great Famine, and the Black Death. Then they recovered to reach a plateau which they maintained for almost 300 years, before falling on the eve of industrialization. The data show that average heights in England in the early nineteenth century were comparable to those in Roman times, and that average heights reported between 1400 and 1700 were similar to those of the twentieth century. This chapter also discusses the association of heights across time with some potential determinants and correlates (real wages, inequality, food supply, climate change, and expectation of life), showing that in the long run heights change with these variables, and that in certain periods, notably the thirteenth and fourteenth centuries, the associations are observable over the shorter run as well. We also examine potential biases surrounding the use of skeletal remains.
