The rise of the gig economy is disrupting business models across the globe. Platforms’ digital work intermediation has had a profound impact on traditional conceptions of the employment relationship. The completion of ‘tasks’, ‘gigs’, or ‘rides’ in the (digital) crowd fundamentally challenges our understanding of work in modern labour markets: gone are the stable employment relationships between firms and workers, replaced by a world in which everybody can be ‘their own boss’ and enjoy the rewards—and face the risks—of independent businesses. Is this the future of work? What are the benefits and challenges of crowdsourced work? How can we protect consumers and workers without stifling innovation? Humans as a Service provides a detailed account of the growth and operation of gig-economy platforms, and develops a blueprint for solutions to the problems facing on-demand workers, platforms, and their customers. Following a brief introduction to the growth and operation of on-demand platforms across the world, the book scrutinizes competing narratives about ‘gig’ work. Drawing on a wide range of case studies, it explores how claims of ‘disruptive innovation’ and ‘micro-entrepreneurship’ often obscure the realities of precarious work under strict algorithmic surveillance, and the return to a business model that has existed for centuries. Humans as a Service shows how employment law can address many of these problems: gigs, tasks, and rides are work—and should be regulated as such. A concluding chapter demonstrates the broader benefits of a level playing field for consumers, taxpayers, and innovative entrepreneurs.

AbstractNocardia species are an uncommon but important cause of keratitis. The purpose of this review is to discus previous published papers relation to the epidemiology, etiology, diagnosis and management of Nocardia keratitis. Nocardia asteroides is the most frequently reported from Nocardia keratitis. Pain, photophobia, blepharospasm and lid swelling are mainly clinical manifestations. Usual risk factors for Nocardia keratitis are trauma, surgery, corticosteroids, and contact lens wear. Several antibiotics were used for treatment of Nocardia infection but according to studies, topical amikacin is the drug of choice for Nocardia keratitis. Topical steroid should not prescribe in these patients. In conclusion, although Nocardia keratitis is rare, early diagnosis and treatment are essential to prevent any scar formation and preserve a good visual acuity.

AbstractDigital technology is playing an increasingly visible role in the organisation of many people’s work—as well as large parts of their lives more broadly. The concerns of emancipatory technology studies, or other critical accounts of technology, are often focused on finding alternative uses of technology. In many workplace contexts—from call centres to platform work—the imperatives of capital are deeply written into these technologies. Yet at the same time, many capitalist technologies are playing a key role facilitating emerging workers’ struggles. For example, in the case study examined here, Deliveroo drivers rely on communication technologies like WhatsApp to organise against algorithmic management. Drawing on an ongoing workers’ inquiry, this paper seeks to consider what a workerist approach to digital technology can add to these debates. The paper outlines the challenges and opportunities for a “digital workers’ inquiry,” considering how this approach combines research with organising. The argument is divided into two main parts: first, the need for inquiries in digital work and the importance of these and second, how the process of inquiry and co-research (and the methods these involve) can be adapted and refined with digital technology. By starting the critique of technology from the workplace, this paper proposes a workerist account of how technologies can be destroyed or re-appropriated, starting from a reading of workers’ struggle.

PurposeThis article aims to discuss how concepts from the analog world apply to a purely digital environment, and look in particular at how authenticity needs to be viewed in the digital world in order to make some form of validation possible.Design/methodology/approachThe article describes authenticity and integrity in the analog world and looks at how to measure it in a digital environment.FindingsAuthenticity in the digital world generally means, in a purely technical sense, that a document's integrity has been checked using mathematical algorithms against other copies on independently managed servers, and that provenance records show that the document has a clearly established succession from a clearly defined original. Readers should recognize that this is different than how one defines authenticity and integrity in the analog world.Originality/valueMost of the key issues surrounding digital authenticity have not yet been tested, but they will be when the economic value of an authentic digital work reaches the courts.
