First, there were two independent clinical psychologists who were present or on call 24 hours a day. They had the power to intervene and to remove anyone from the study if they thought they were in distress.
Second, we had paramedics and security guards on hand and ready to intervene at a moment’s notice if anything untoward happened in the study.
Third, the study was constantly monitored by members of a five-person independent ethics panel. This was chaired by a Member of Parliament and also included members of the Holocaust Educational Trust, the Howard League for Penal Reform, the BBC’s Independent Editorial Policy Unit and a senior academic psychologist. This committee had the power to change the way the study as a whole was run and to terminate it if they had ethical concerns.

La revolución industrial de Alemania se produjo en el siglo XIX, luego del proceso de industrialización que ya venía desarrollando Inglaterra. Esta última facilitó la revolución que Alemania viviría ya que invirtió capitales, maquinaria y debió abastecerse de mano de obra especializada, y se radicó con más fuerzas ya que las regiones de Alemania contaban con variados recursos naturales. Este acontecimiento trajo consecuencias políticas y por supuesto económicas, las que influyeron de forma importante en todos los aspectos.
Espero que ayude
I would say : landslides, tsunamis, and liquefaction.
