Before electricity, night was something akin to the deep sea: just as we could not descend much below the water surface, we also could not investigate the night for more than a short distance, and for a short period of time. Things changed with two inventions: the Bathysphere to plumb the ocean floor, and electricity to light the night for sustained exploration. Exploration led to dominance, and night has become indistinguishable from day in many parts of the world. The benefits of electric light are myriad, but so too are the possible detriments of loss of dark at night, including poor sleep, obesity, diabetes, cancer, and mood disorders. Our primordial physiological adaptation to the night and day cycle is being flummoxed by the maladaptive signals coming from electric lighting around the clock. The topic of sleep and health has finally attained scientific respect, but dark and health is not yet fully appreciated.

Chapter 1 explores Woolf’s writings up to the end of 1925 in relation to scientific ideas on wave-particle duality, providing the ‘retrospect of Woolf’s earlier novels’ which Michael Whitworth has suggested shows that she was working ‘in anticipation of the physicists’. The chapter as a whole challenges this idea of anticipation, showing that Woolf was actually working in parallel with physicists, philosophers, and artists in the early twentieth century, all of whom were starting to question dualistic models and instead beginning to develop complementary ones. A retrospect on wave-particle duality is also provided, making reference to Max Planck’s work on quanta and Albert Einstein’s development of light quanta. This chapter pays close attention to Woolf’s writing of light and her use of conjunctions, suggesting that Woolf was increasingly looking to write ‘both/and’ rather than ‘either/or’. Among other texts, it considers Night and Day, Mrs Dalloway, and ‘Sketch of the Past’.

Automatic sleep staging based on inter-beat fluctuations and motion signals recorded through a pressure bed sensor during sleep is presented. The analysis of the sleep was based on the three major divisions of the sleep time: Wake, non-rapid eye movement (nREM) and rapid eye movement (REM) sleep stages. Twelve sleep recordings, from six females working alternate shift, with their respective annotations were used in the study. Six recordings were acquired during the night and six during the day after a night shift. A Time-Variant Autoregressive Model was used to extract features from inter-beat fluctuations which later were fed to a Support Vector Machine classifier. Accuracy, Kappa index, and percentage in wake, REM and nREM were used as performance measures. Comparison between the automatic sleep staging detection and the standard clinical annotations, shows mean values of [Formula: see text]% for accuracy [Formula: see text] for kappa index, and mean errors of 5% for sleep stages. The performance measures were similar for night and day sleep recordings. In this sample of recordings, the results suggest that inter-beat fluctuations and motions acquired in non-obtrusive way carried valuable information related to the sleep macrostructure and could be used to support to the experts in extensive evaluation and monitoring of sleep.

Abstract This essay considers the unworldly setting of Jean Rolin’s novel Ormuz (2013), composed around the attempt by a shadowy character named Wax to swim across the Strait of Hormuz. This twenty-one-nautical-mile-wide stretch of sea separating Iran from the Arabian Peninsula, through which is shipped 35 percent of the world’s petroleum, is a waterway of the utmost geopolitical importance, its harbors built not for dreamy swimmers but for giant oil tankers and the elaborate maritime-military infrastructure assuring their passage. Such a setting would seem to stand as a bleak other to the novel as genre. Yet if one thinks of the history of the novel as inseparable from that of carbon capitalism (as Amitav Ghosh has argued), such a claim is reversed—this site where powerful strategic interests drive the flow of oil, capital, and power is the place of the continual making and unmaking, by night and day, of the world order, and thereby of the modern novel. The essay reflects on what Wax’s weird wager—as an emblem for a remarkable narrative wager—may owe to such intertexts as Google, Descartes’s Meditations, and Jules Verne’s Tour du monde, and argues for reading Ormuz as an ecological novel for our times.

Between 1915 and 1923, Virginia Woolf published her first three novels (The Voyage Out, Night and Day, and Jacob’s Room) as well as some of her most iconic essays and stories. This chapter examines that work with particular attention to how Woolf’s early fiction describes modern novels, placing it in conversation with her essays on the modern novel. Woolf turned repeatedly to the problem of how to achieve the freedoms of a new modernity, and her early work struggles to imagine a new kind of novel while acknowledging that this new kind of novel does not exist: not quite yet. This chapter examines Woolf’s deliberately undetermined vision of modernity, tracing how her early work persistently ponders and imagines what a new era of writing will offer even as she refuses to specify and delimit what has yet to come to pass.

Focusing on the period up to 1924, this chapter explores Virginia Woolf’s engagement with London as much-loved home, as literary subject (from Night and Day to Jacob’s Room and Mrs Dalloway), and as professional milieu. It considers Woolf’s roots in Hyde Park Gate, her move from Kensington to Bloomsbury after the death of her father, Leslie Stephen, and the establishment of the Bloomsbury Group. At the same time, this chapter widens the lens to look at the larger London literary scene. This was a resource to which Woolf gained access through a large network of friends, including, but not limited to, other Bloomsbury Group members, and professional contacts acquired through her work as publisher along with Leonard Woolf at the Hogarth Press. The chapter closes with Woolf’s move back into the ‘centre of things’ in Bloomsbury in 1924 as both she and the press began to outgrow Richmond.
