One of the most striking features of the 21st century is the widespread adoption of information technology in every aspect of the modern life of individuals, society, or nation-states.When compared to land, sea, air, and space, cyberspace has unique features. Its ""geography"" is easily modified, oceans and mountains are hard to be changed, but entire cyberspace regions can be turned on or off with a button click. Moreover, anonymity, the low cost of acquiring or developing offensive capabilities, and the plausible deniability of actions have turned this dimension into a theater of operations for nation-states.This book does not focus on the worst-case scenario where cyber offensive actions will revolutionize war. Instead, it intends to provide empirical analysis regarding the current state of cyber conflict. This book presents evidence of 29 countries engaging in state-sponsored actions and 85 nations acquiring cyber offensive technologies from private vendors. The numbers challenge the average perception of concentration of cyber capabilities in a few ""traditional"" actors.Cyberspace provides alternatives for the bargaining and interactions to nation-states below the threshold of the use of force. As a result, actors can achieve strategic outcomes and influence the balance of power without resorting to an armed attack and minimizing the risk of a military or nuclear response from their targets.

The Gospel Coaltion Award of DistinctionChristian LivingOutreach Resource of the YearThe digital age is in the business of commodifying our attention. The technologies of our day are determined to keep us scrolling and swiping at all costs, plugged into a feedback loop of impatience, comparison, outrage, and contempt. Blind to the dangers, we enjoy its temporary pleasures, unaware of the damage to our souls.Jay Kims Analog Church explored the ways the digital age and its values affect the life of the church. In Analog Christian, he asks the same question of Christian discipleship. As the digital age inclines us to discontentment, fragility, and foolishness, how are followers of Jesus to respond? What is the theological basis for living in creative resistance to the forces of our day? How can Christians cultivate the contentment, resilience, and wisdom to not only survive but to thrive as we navigate the specific challenges of our age?

John Wilson did more than anyone else to prevent and cure blindness, and help blind people, throughout the world between the 1940s and his death in 1999. In addition, he made a significant contribution to the cause of disabled people in general. His achievements deserve comparison with those of other charismatic figures such as Helen Keller and Albert Schweitzer. A man of action and unflagging energy, with exceptional determination, imagination and compassion, and analytical and organizational ability, he changed millions of peoples lives for the better by developing systems and techniques for preventing and curing blindness, and by spurring on the process by which blind people have come to be able to play a full, active and creative role in society. His story is a moving one. Blinded himself in a school experiment in 1931 at the age of twelve, he went on to read law at Oxford. After joining the National Institute for the Blind as an administrator, he took part in 1946-7 in an epic government-sponsored tour of the African and Middle Eastern territories in what was then the British Empire that lasted nine months, studying the intractable problems of blindness there. It led to the formation of what was to become the Royal Commonwealth Society for the Blind, now known as Sight Savers International. In the wake of his sustained campaigns for the cure and prevention of blindness, above all in Africa and the Indian sub-continent, underpinned by the indomitable support of his wife Jean, John Wilson became a leading activist and mentor for blind and disabled people both at the UN and world-wide; and he was to found further important institutions such as the International Agency for the Prevention of Blindness and Impact, which focusses on the universal challenge of avoidable disability. He was an enthusiastic globe-trotter, a powerful orator, a much-loved member of his family and a highly respected friend and colleague of large numbers of people with whom he worked across the continents. This inspiring tale of how one remarkable man travelled the world and transformed countless lives will have a strong appeal to the general public. It will also be of direct interest to people involved in charities and other institutions, particularly those concerned with blindness and disability. Meticulously researched, it is primarily based on John Wilsons Braille diaries and his other papers, the records at Sight Savers and interviews in many different countries with people who knew him. Lord Colin Low, chairman, Royal National Institute of the Blind: I have just finished reading Blindness and the Visionary and felt I must write and tell you how enthralling I found it...[it is] an absolutely splendid addition to the literature on blindness, in every way worthy of its subject. Ramachanda Pararajasegaram, consultant to World Health Organization, in International Agency for the Prevention of Blindness Review: ...the story, related with sensitivity and objectivity, of a unique personality destined...to become a globally renowned voice, rendering a clarion call to action, against avoidable disablement...I have had immense enjoyment reading this book, which has deepened my understanding even better of the humanity behind John Wilson. I feel re-inspired, re-enthused and re-energized to help carry out what we have collaboratively pledged to do...No reader would fail to be inspired by this book on [his] life and work, so expertly put together by John Coles...

Die Grundprinzipien der Hygiene umzusetzen war eine der segensreichsten Leistungen unserer Zivilisation. Doch dann wurde der Krieg gegen die Keime zum Grundprinzip der Medizin erhoben. Bewaffnet mit Antibiotika, Impfungen & Co bekampfen wir Viren und Bakterien und ubersehen dabei, dass wir selbst aus solchen Mikroben bestehen dem Mikrobiom, das eng mit unserem Immun- und Nervensystem kooperiert und fur den Korper gleichbedeutend ist wie ein lebenswichtiges Organ. Bert Ehgartner (Die Akte Aluminium) beschreibt, wie uns eine fehlgeleitete Medizin in die Hygienefalle tappen lasst und welch dramatische Auswirkungen der Krieg gegen die Keime auf unsere Gesundheit hat. Bert Ehgartners bewundernswert grundlich recherchiertes Buch ist ein Appell zum Friedensschluss: Um einen Weg aus der Sackgasse einer immer teureren und letztlich vergeblichen Eskalation zu finden, muss die moderne Medizin umdenken. Bakterien und Viren sind nicht die Achse des Bosen, der mit Desinfektion, Antibiotika und Impfungen zu Leibe geruckt werden muss. Langfristige Gesundheit erfordert vielmehr eine Symbiose mit diesen kleinen Helfern. Ich bin begeistert von diesem Buch!Martin Hirte, Kinderarzt und Bestsellerautor (Impfen Pro & Contra)

The initial impetus for his research was the book series Ether-Physics and-Philosophy Volume 1-4 (German edition) by Prof Alfred Evert, last published in 2011. Using basic mathematics, he identifies false assumptions and is questioning nothing less than our common astrophysical world model. Today, it seems undisputed that our universe must contain some dark matter and that the vacuum is filled with infinite energies. Highly admired academics and despised lunatics speculate about parallel worlds and the possibility of multiple dimensions. Esotericism and science equally work with vague definitions and often wrong assumptions. As a non-academic amateur, Christian Frambs doubts were growing the more he researched the fundaments of our dominant and very rarely questioned astrophysical explanation of the world. The authors brother - an experienced Navigator and Mariner - convinced Christian Frambs to write an essay covering his thoughts, analyses, questions and alternative conclusions. Rewriting the proverb that an apple doesnt just fall far from the tree describes the spirit of his work. The key element and basis of his suggestion of another alternative world model is the good old and widely forgotten physical concept of the ether. The Key Statements of this publication: - All perceptions are illusionary projections of reality. - Only two facts are undoubted: There must be SOMETHING and MOTION. - The ether-theorem is based on just these two hypotheses: a single real substance which is vibrating in itself. - Many different movement patterns represent the phenomena, from the photon, electron and atom to the stars and galaxies. - There are no fixed particles. In analogy to sound, only the structures of MOTION are wandering forward within the ether. - Gravity only exists in the immediate vicinity of a celestial body, but its cause is not based on mass. - There are also no forces attracting the mass; the Earth, for example, drifts passively in an ether-whirlpool around the Sun. - The geostationary satellites, for example, provide clear proof, as they are contrary to the usual laws constantly dancing around. - Everything is made of ONE. This ancient wisdom/spiritual concept becomes a physical/scientific reality: The homogeneous ether fills the universe without gaps, and all phenomena are only movements within this medium. - New approaches for a more understandable and plausible world model are presented.

Weltweit sinkt die mentale Leistungsfahigkeit, insbesondere schon bei jungen Menschen, wahrend die Depressionsraten dramatisch steigen. Jeder Vierzigste leidet mittlerweile an Alzheimer, und das bei rapide sinkendem Erkrankungsalter. Doch die Ursachen dafur werden nicht beseitigt, ganz im Gegenteil. Kann das nur Zufall sein?Das indoktrinierte Gehirn prasentiert einen weitgehend unbekannten, wirkmachtigen neurobiologischen Mechanismus, dessen meist unbemerkte, aber mannigfache Storung diesen katastrophalen Entwicklungen zugrunde liegt.Dr. Michael Nehls, Mediziner und international renommierter Molekulargenetiker, legt in diesem Buch eine erschutternde Indizienkette dar, die darauf hinweist, dass sich hinter diesen zahlreichen negativen Einflussen ein gezielter, meisterhaft ausgefuhrter Angriff auf unsere Individualitat verbirgt mit dem Ziel, den Menschen ihre Fahigkeit zum selbststandigen Denken zu nehmen.Doch es ist noch nicht zu spat. Indem Nehls diese gehirnschadlichen Prozesse aufdeckt und individuell umsetzbare Gegenmanahmen beschreibt, bringt er Licht und Hoffnung in dieses schicksalhafte Kapitel der Menschheitsgeschichte. In diesem wird sich nichts Geringeres entscheiden als die Frage, ob unsere Spezies ihre Menschlichkeit und ihre schopferische Kraft bewahren kann oder ob sie diese unwiederbringlich verlieren wird.

Una exploración profundamente original de los grandes enigmas que la ciencia aún no ha podido resolver. La ciencia ha transformado nuestra vida más allá de lo imaginable. Nos ha llevado al espacio, ha descifrado el genoma humano y ha creado maquinas que aprenden. Pero, en su nucleo, persisten misterios que ningun avance ha conseguido despejar. Sonia Contera, catedratica de Fisica en Oxford y una de las cientificas mas influyentes del panorama internacional, nos invita a explorar esas fronteras del conocimiento donde las ecuaciones se detienen y comienza el asombro. Desde los enigmas de la fisica cuantica, el origen de la vida y el misterio del envejecimiento, hasta los retos de la inteligencia artificial y la conciencia, Contera revela como cada intento de respuesta ha cambiado nuestra forma de entender el universo... y a nosotros mismos. Un viaje fascinante y accesible por los desafios mas profundos de la ciencia contemporanea y por las preguntas que seguiran marcando el futuro de la humanidad.
