Investigations into new technologies, employment and working conditions are timeless and consequently have occupied research, public policy, and popular fiction for centuries. However, in addition to the uncertainty created by the introduction of new technologies, the current coronavirus pandemic, with its associated impact on health and the economy, has led to increased volatility across the globe. The global medical crisis arising from the worldwide spread of COVID-19 is predicted to lead to a global economic crisis and subsequent deep depression. The resultant economic, social and political repercussions are likely to be felt for years or even decades to come, equalling the great depression of the last century. Consequently, it is difficult to make long-term accurate predictions about the impact of new technologies on industry, society, and labour. In this context, the aim of this introductory article to the themed volume is to consider the potential challenges and opportunities associated with the Fourth Industrial Revolution technologies and potential impacts on work and workplaces. This introductory article comprises an international collection of research that examines the impact of technological change on employment and working conditions with consideration given to the additional impacts of the COVID-19 crisis.

This article explores critical shifts in the governance of religion amid massive urbanization and technological advances in contemporary China. Since the turn of the millennium, along with rapid urban transformation, the Chinese state has greatly expanded its reach into and surveillance of religious communities. At the same time, tensions between state initiatives and religious communities have come to the forefront of public attention. So far, scholarly attention has mostly focused on the repression of religious communities, especially Christians. The goal of this article is to highlight broader transitions in the ways religion is governed in China and to reflect on how these transitions should be understood alongside the government's social and political agendas. The advancement of technologies and the extension of the bureaucratic system to maintain control of a rapidly urbanizing society, I argue, have brought about a “technological turn” of secularism in China, which will have a far-reaching impact on religious life.

This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm field trials for varietal evaluation and demonstration purposes.

This article considers the role of civil society in the development of new standards around weapons. The broad but informal roles that civil society has undertaken are contrasted with the relatively narrow review mechanisms adopted by states in fulfilment of their legal obligations. Such review mechanisms are also considered in the context of wider thinking about processes by which society considers new technologies that may be adopted into the public sphere. The article concludes that formalized review mechanisms, such as those undertaken in terms of Article 36 of Additional Protocol I (1977) of the Geneva Conventions of 1949, should be a focus of civil society attention in their own right as part of efforts to strengthen standard-setting in relation to emerging military technologies.

The benefits of employing computed tomography (CT) into the planning process of radiotherapy has been well established over the last 20 years. The cross sectional images provide invaluable information that enable clinicians to plan patients treatment with confidence. More recently there has been the development of the CT-simulator (CT-sim), however its place in the clinical setting has still to be established.

One of the most anticipated questions is “will the CT-simulator replace the present conventional treatment simulator as a tool for simulation?” There appear to be tremendous reasons why it should, but there are also many issues that need to be addressed.

This discussions aims to critically assess the practical and technical aspects of the new technology, by means of reviewing published literature. The aim is to decipher whether its introduction into the planning process is realistic and appropriate for all radiotherapy patients, and whether it has the possibility to replace the treatment simulator.

Issues concerned with image production, simulation (virtual), planning, cost, quality assurance (QA) and patient criteria (i.e. radical and palliative patients) have been reviewed. The Study concludes that the CT-sim has the realistic possibility to dramatically improve the treatment intent of all radiotherapy patients. Although there are situations where the treatment simulator appears to supersede the CT-sim, there still appears to be a place for it within the planning process.

Research plots that are large enough to accommodate regular farm machinery are thought to contain too much field variation to allow reliable interpretation of experimental results. This study was conducted to determine whether experimental error was controlled on a wide variety of agricultural field trials that used plots larger than normally used by researchers. The investigation included trials conducted on an experiment station and trials conducted on actual commercial farms. The planning and management of the experiments ranged from those completely conducted by university researchers to those completely done by farmers.

The level of experimental error in all the trials was well within the limits normally accepted by researchers in agronomy. Plots ranging in length from 125 to 1200 feet and as wide as one or two passes of standard farm machinery gave experimental results that were statistically sound. Statistical requirements for randomization and replication were all met.

The ability to use large plots and farmer participation enhances the testing of new technology on farms. This leads to new opportunities to test crop production factors in a systems setting under actual farm conditions. The statistical reliability of the on-farm designs analyzed in this study should increase cooperation among researchers, extension workers, and farmers in research activities.
