Facing Fear is the inspiring true story of Lisa Blair, who on 25 July 2017 became the first woman to sail solo around Antarctica. She very nearly didn’t live to tell the tale. Seventy-two days into her circumnavigation, when Lisa was more than 1000 nautical miles from land, the mast of Climate Action Now came crashing down in a ferocious storm. In freezing conditions, Lisa battled massive waves and gale-force winds, fighting through the night to save her life and her boat. Following her ordeal, Lisa relied on her unbreakable spirit to beat the odds and complete her world record. With unwavering focus and determination, she sailed home, completing her journey after 183 days. This is the story of her remarkable voyage.
This book provides an empirical and philosophical investigation of self-tracking practices. In recent years, there has been an explosion of apps and devices that enable the data capturing and monitoring of everyday activities, behaviours and habits. Encouraged by movements such as the Quantified Self, a growing number of people are embracing this culture of quantification and tracking in the spirit of improving their health and wellbeing. The aim of this book is to enhance understanding of this fast-growing trend, bringing together scholars who are working at the forefront of the critical study of self-tracking practices. Each chapter provides a different conceptual lens through which one can examine these practices, while grounding the discussion in relevant empirical examples. From phenomenology to discourse analysis, from questions of identity, privacy and agency to issues of surveillance and tracking at the workplace, this edited collection takes on a wide, and yet focused, approach to the timely topic of self-tracking. It constitutes a useful companion for scholars, students and everyday users interested in the Quantified Self phenomenon.

An enchanting collection containing books four, five, and six of #1 New York Times bestselling author Julia Quinn’s beloved Regency-set Bridgerton novels—Romancing Mister Bridgerton; To Sir Phillip, with Love; and When He Was Wicked—now a series created by Shondaland for Netflix. Romancing Mister Bridgerton Penelope Featherington has secretly adored her best friend’s brother from afar for forever—until she stumbles across Colin Bridgerton’s deepest secret and fears she doesn't know him at all. Meanwhile, Colin is tired of his reputation as an empty-headed charmer and of the notorious gossip columnist Lady Whistledown. Upon his return to London, he discovers everything has changed—especially Penelope Featherington! The girl who was always simply there suddenly haunts his dreams. When he discovers that Penelope has secrets of her own, this elusive bachelor must decide . . . is she his biggest threat or his promise of a happy ending? To Sir Phillip, With Love Sir Phillip knew that Eloise Bridgerton was a spinster, and so he’d proposed, figuring she’d be timid and desperate to marry. Except . . . she wasn’t. And all he wanted to do was kiss her . . . As for Eloise, she couldn’t marry a man she had never met! Yet, she found herself in a carriage on her way to meet her perfect match.

But that was then . . . Now Michael is the earl and Francesca is free, but she still sees him as a dear friend. Michael dares not profess his love . . . until one dangerous night, passion proves stronger than even the most wicked of secrets . . .
This book guides animal ecologists, biologists and wildlife and data managers through a step-by-step procedure to build their own advanced software platforms to manage and process wildlife tracking data. This unique, problem-solving-oriented guide focuses on how to extract the most from GPS animal tracking data, while preventing error propagation and optimizing analysis performance. Based on the open source PostgreSQL/PostGIS spatial database, the software platform will allow researchers and managers to integrate and harmonize GPS tracking data together with animal characteristics, environmental data sets, including remote sensing image time series, and other bio-logged data, such as acceleration data. Moreover, the book shows how the powerful R statistical environment can be integrated into the software platform, either connecting the database with R, or embedding the same tools in the database through the PostgreSQL extension Pl/R. The client/server architecture allows users to remotely connect a number of software applications that can be used as a database front end, including GIS software and WebGIS. Each chapter offers a real-world data management and processing problem that is discussed in its biological context; solutions are proposed and exemplified through ad hoc SQL code, progressively exploring the potential of spatial database functions applied to the respective wildlife tracking case. Finally, wildlife tracking management issues are discussed in the increasingly widespread framework of collaborative science and data sharing. GPS animal telemetry data from a real study, freely available online, are used to demonstrate the proposed examples. This book is also suitable for undergraduate and graduate students, if accompanied by the basics of databases.
