In Ten Trips neuropsychologist Andy Mitchell takes ten different
psychedelic drugs in ten different settings, puncturing the hype
while providing the fullest picture yet of their limitlessly
fascinating possibilities. Once demonised and still largely
illegal, psychedelic drugs are now officially a 'breakthrough
therapy', used to treat depression, trauma and addiction and to
enhance well-being. But as neuropsychologist Andy Mitchell shows in
this deeply serious yet wildly entertaining investigation, this
approach misses what is so strange and valuable about them: the
psychedelic experience itself. In Ten Trips he takes ten different
compounds, some famous, others obscure, journeying from a
neuroimaging lab in London to the Colombian Amazon via Silicon
Valley and his friend's basement kitchen. His encounters with
scientists and gangsters, venture capitalists and con-men,
psychonauts and shamans provide a panoramic view of psychedelics
today: their capacity for healing but also trauma, for
transcendence and corruption, profundity and hilarity. By removing
psychedelics from their indigenous and underground cultures, we
risk losing the very things we need to harness them. To make them
safe or normal might ultimately destroy what makes them potent.
That potential is indeed great, not as an antidote to mental
illness - none exists - but as a way of changing our whole
perspective on mental health and flourishing. Ten Trips is a
dazzling, perception-shifting odyssey that shows how psychedelics
can re-enchant us with the world.
Learn how to get better answers in map analysis when you use
spatial measurements and statistics. Spatial measurements and
statistics give you a powerful way to analyze geospatial data, but
you don't need to understand complex mathematical theories to apply
statistical tools and get meaningful results in your projects. The
Esri Guide to GIS Analysis, Volume 2: Spatial Measurements and
Statistics, second edition, builds on Volume 1 by taking you to the
next step of GIS analysis. Learn to answer such questions as, how
are features distributed? What is the pattern created by a set of
features? Where can clusters be found? This book introduces readers
to basic statistical concepts and some of the most common spatial
statistics tasks: measuring distributions, identifying patterns and
clusters, and analyzing relationships. Updated with the latest and
most useful software tools and revised explanations, each chapter
in The Esri Guide to GIS Analysis, Volume 2 is organized to answer
basic questions about the topic. Explore how spatial statistical
tools can be applied in a range of disciplines, from public health
to habitat conservation. Learn how to quantify patterns beyond
visualizing them in maps. Examine spatial clusters through an
updated chapter on identifying clusters. Use The Esri Guide to GIS
Analysis, Volume 2, second edition, to understand the statistical
methods and tools that can move your work past mapping and
visualization to more quantitative statistical assessment.
A neuropsychologist takes ten different psychedelic drugs in this
panoramic, profound and wildly entertaining investigation.
'Original and thrilling' Mike Jay, author of Psychonauts 'Utterly
compelling' Mark Miodownik, author of Stuff Matters 'A hair-raising
hurtle of a ride' Henry Shukman, author of One Blade of Grass 'The
psychedelic world has been waiting for this book' Professor Erika
Dyck Psychedelics may have made a comeback but they still remain a
mystery. They are now a 'breakthrough therapy' for mental illness
but the truth is we have only a vague idea how they work and there
is a limit to what science alone can reveal. To have any hope of
understanding them fully, we need first to broaden our view -
dramatically - of what they are. In this daring,
perception-shifting odyssey, clinical neuropsychologist Andy
Mitchell takes ten different drugs in ten different settings,
journeying from a neuroimaging lab in London to the Colombian
Amazon via Silicon Valley and his friend's basement kitchen. His
encounters with scientists and gangsters, venture capitalists and
con men, psychonauts and shamans, as well as with the drugs
themselves, reveal the reality of psychedelics in all their
richness, darkness, hilarity, wonder and strangeness. We see that
the drive to extract these substances from their indigenous and
underground cultures comes with risk as well as opportunity, and
that to make them safe or normal might ultimately destroy what
makes them potent. We also see, more vividly than ever before, what
makes them so rapturously enchanting and confounding. 'Beguiling,
captivating, mind-expanding. It's impossible to read this book and
not be tempted to replicate some of its wild, sanity-stretching
forays into the peculiarities of human perception' Stuart Ritchie,
author of Science Fictions 'A dazzling, timely book, as deep and
poignant as it is madcap and hilarious' Mark Lythgoe, Director of
the Centre for Advanced Biomedical Imaging, University College
London
Do more with your GIS and understand the foundation of spatial
analysis: geographic patterns and relationships. A geographic
information system (GIS) enables so much more than mapping. A GIS
inherently enables spatial analysis that can give you a better
understanding of your geographic data. GIS analysis reveals answers
to questions like: Where is it? Where's the most and least? How
much is where? What's inside? What's nearby? What's changed But how
do you get started? The second edition of The Esri Guide to GIS
Analysis, Volume 1 shows how and more. With easier to read maps and
text, The Esri Guide to GIS Analysis, Volume 1, second edition,
dives beneath the surface of mapping, beyond displaying data to
using it to reveal geographic insights. Learn the basic concepts of
spatial analysis and GIS. Build on that understanding with
essential map-building skills to unveil and display patterns and
relationships. The Esri Guide to GIS Analysis, Volume 1, second
edition, also includes a guide to online lessons that reinforce the
concepts and demonstrate GIS application. Written for both new and
experienced GIS users using an easy to follow format, the second
edition of The Esri Guide to GIS Analysis, Volume 1 helps you build
a foundation of the basic tasks needed to handle a wide range of
analysis applications and prepares you for more advanced GIS
skills.
The third volume in the Esri Guide to GIS Analysis series, Modeling
Suitability, Movement, and Interaction describes practical
applications of modeling concepts in a geographic information
system (GIS). Modeling allows users to explore different scenarios
and the impacts of various options, before making a decision.This
book covers a broad range of methods for spatial interaction, site
selection, routing, and scheduling, and explains the theory behind
them so users can better interpret the analysis results. It also
describes how a particular method is implemented within a GIS. With
full-color maps and illustrations and sample applications, this
book will help students studying GIS and professional GIS analysts
better use models to evaluate locations and analyze movement
