Though there is a large potential market for laser robots for sheet‐metal cutting, there are still functional problems to be overcome.

Interrelations of writings in a complex field such as studies of science, technology and society, turn out to be highly patterned when data on author co‐citations are statistically analysed and mapped. For both authors and specialities, the maps reveal structures of subject matter and intellectual impact, based on the perceptions of hundreds of citers since 1972. A new tool thus is available to historians and others concerned with a field's intellectual development.

Detrimental impacts on social and ecological well-being of excessive fashion consumption and production practices are posing threats on future generations. Therefore, the need for sustainable solutions and endorsing them through social marketing efforts is more urgent than ever. From the consumption angle, this study aims to explore the driving forces behind consumers’ restless desire for the new and the growing need to consume sustainably.

This paper is conceptual in nature, and through a review of the literature in fashion, consumer, sustainability and social marketing studies, it examines why consumer desire for the new is so profound and how it conflicts with sustainability goals of the fashions industry. With a macrosocial approach, it reveals how multiple constituents of the fashion system can contribute toward sustainability goals.

This study explains consumers’ psychological and social needs driving their restless desire for the new and the role of fast fashion companies fuelling this desire. It also discusses the consequences of excessive fashion consumption and presents social marketing solutions at micro, meso and macro levels with upstream and downstream effects toward sustainability goals.

Considering the increasing consciousness about the negative impacts of excessive fashion consumption, this study suggests both practical and social implications that are associated with multiple stakeholders including consumers, fashion companies and public policymakers.

This study reveals in detail the challenges and potential social marketing solutions at micro, meso and macro levels, concerning the conflict between consumers’ restless desire for the new and the pressing need to consume more sustainably.

This paper aims to shed light into money laundering using bitcoin. Digital payment methods are increasingly used by criminals to launder money obtained through cybercrime. As many forms of cybercrime are motivated by profit, a solid cash-out strategy is required to ensure that crime proceeds end up with the criminals themselves without an incriminating money trail. The authors examine how cybercrime proceeds can be laundered using services that are offered on the Dark Web.

Focusing on service-percentages and reputation-mechanisms in underground bitcoin laundering services, this paper presents the results of a cash-out experiment in which five mixing and five exchange services are included.

Some of the examined services provide an excellent, professional and well-reviewed service at competitive cost. Whereas others turned out to be scams, accepting bitcoin but returning nothing in return.

The authors discuss what these findings mean to law enforcement, and how bitcoin laundering chains could be disrupted.

These cash-out strategies are increasingly facilitated by cryptocurrencies, mainly bitcoin. Bitcoins are already relatively anonymous, but with the rise of specialised bitcoin money laundering services on the Dark Web, laundering money in the form of bitcoins becomes available to a wider audience.
