Blue Light Hours


Book Description

“Astonishingly beautiful . . . It’s a revelation.”—Jenny Offill, New York Times bestselling author of Weather One of Electric Literature’s “75 Books by Women of Color to Read in 2024” From the National Book Award-winning translator, an atmospheric and wise debut novel of a young Brazilian woman’s first year in America, a continent away from her lonely mother, and the relationship they build over Skype calls across borders In a small dorm room at a liberal arts college in Vermont, a young woman settles into the warm blue light of her desk lamp before calling the mother she left behind in northeastern Brazil. Four thousand miles apart and bound by the angular confines of a Skype window, they ask each other a simple question: what’s the news? Offscreen, little about their lives seems newsworthy. The daughter writes her papers in the library at midnight, eats in the dining hall with the other international students, and raises her hand in class to speak in a language the mother cannot understand. The mother meanwhile preoccupies herself with natural disasters, her increasingly poor health, and the heartbreaking possibility that her daughter might not return to the apartment where they have always lived together. Yet in the blue glow of their computers, the two women develop new rituals of intimacy and caretaking, from drinking whiskey together in the middle of the night to keeping watch as one slides into sleep. As the warm colors of New England autumn fade into an endless winter snow, each realizes that the promise of spring might mean difficult endings rather than hopeful beginnings. Expanded from a story originally published in The New Yorker, and in elegant prose that recalls the work of Sigrid Nunez, Katie Kitamura, and Rachel Khong, Bruna Dantas Lobato paints a powerful portrait of a mother and a daughter coming of age together and apart and explores the profound sacrifices and freedoms that come with leaving a home to make a new one somewhere else.




Neuronal Input Pathways to the Brain's Biological Clock and their Functional Significance


Book Description

Rhythmic changes in physiology and behaviour within a 24 h period occur in living organisms on earth to meet the challenges associated with the daily changes in the external environment. The circadian pacemaker responsible for the temporal internal organisation and the generation of endogenous rhythms of approximately 24 h is located in the hypothalamic suprachiasmatic nucleus (SCN) in mammals. The endogenous period generated by the pacemaker is close to, but generally not equal to 24 h and the biological clock therefore needs to be daily adjusted (entrained) by external cues. The daily alteration of light and darkness due to the rotation of our planet on its own axis in relation to the sun is the most prominent "zeitgeber" which adjusts the phase of the circadian rhythms to the astronomical day length, a process known as photoentrainment. In mammals, light is perceived only through photoreceptors located in the retina. Light information is mediated to the SCN via the retinohypothalamic tract (RHT) by activation of the classical photoreceptor system of rods and cones and a more recently identified system of intrinsic photosensitive retinal ganglion cells (ipRGCs) using melanopsin as a photopigment.

Sleepiness and Human Impact Assessment


Book Description

The World Health Organization supports tools and initiatives in Health Impact Assessment to dynamically improve health and well-being across different sectors. Human Impact Assessment (HuIA) is a relatively new concept. It describes an integrated process that encompasses both Health Impact Assessment and Social Impact Assessment and is used to anticipate the effects of programs, projects and decisions on human health and welfare. Sleep occupies approximately one-third of our lives, but its human impact remains largely unrecognized. The prevalence of excessive sleepiness is recognized to be increasing in industrialized societies. Without doubt, sleepiness and fatigue have high costs in terms of both lives lost and socioeconomic impact. For example, the National Highway Traffic Safety Administration estimates that up to 4% of all fatal crashes are caused by drowsy drivers and that as many as 100,000 deaths per year in the United States may be due to fatigue-related medical errors. Sleepiness and Human Impact Assessment provides a uniquely comprehensive exploration of many different facets of sleepiness in our 24-hour society from the new HuIA point of view. Among the covered issues are the physiology and pathophysiology of sleep, its relationship to daytime alertness, fatigue and drugs, the relevance of sleep-related fatigue in various occupational settings and public safety. This book will be of assistance to physicians, occupational health professionals, ergonomists, researchers and decision-makers as they strive to understand the full significance of sleepiness and to create a culture of accountability in everyday life without sleep-related risks.
