Case 5: becky, age 42, was brought in by local law enforcement after she was found running naked through the town park. when asked what she was doing, she said that it "felt good to be free." when the police asked her to come with them, she became combative and had to be handcuffed. she continued to hiss and spit at the officers until arriving at the hospital, where she smiled broadly and yelled, "home sweet home! " during your interview with her, she seems very excitable but pleasant. she mentions that her run through the park was a celebration. when you ask what she is celebrating, she says that she has been feeling rather down for the past two weeks, but that today she felt great and decided to celebrate with a run. what diagnosis and symptoms would you give becky?

Answer and explanation:

By reading these lines above, considering the scenario described and they behaviour of the patients, I can deduce that what she decided to do was something purely out of impulse. She acted on impulse after a massive feeling of joy that overcame her after having two bad emotionally weeks. Also, she acts nicely in a moment and then agressively changes her behaviours from one second to another. I would guess that the pacient has bipolar disorder.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
