PROBLEM: Somewhere in harbourside Sydney, Australia, a family lives within a high-rise apartment building where the mother is preparing a meal and listening to the radio. Her fourteen year old daughter (Jenny Agutter) and six year old son (Luc Roeg) swim in the building's pool overlooking a view of the ocean while their father (John Meillon), deep in troubled thought, watches them from their balcony.One day, the father takes his children, still in their school uniforms, on a picnic into the Outback. He parks the car and reads while his daughter sets up a blanket with their lunch. Her brother plays nearby with his water gun and toy soldiers. Suddenly, and for reasons unclear to his children, the father announces it is time to go and brandishes a gun, firing several shots at them. The boy thinks it all to be a game but his sister understands the danger and shields her brother as they run from their mad father. She watches in horror as her father returns to the car and sets it on fire before seating himself within and putting a bullet into his head. Quickly, and keeping her brother's eyes averted, the girl retrieves their radio, a scarf, and what food she can carry before setting off into the wilderness with her brother.The siblings walk for hours under the hot sun, calmed by irrelevant radio broadcasts, and walking past a host of wild creatures. Come nightfall, they make a crude camp for themselves, much to the boy's delight. In the morning, the girl leads them up a rocky hillside where she hopes to find some bearings. However, she can see nothing but a broad spanse of wilderness. When they finish their lemonade, the girl opens a can of vegetables from which they drink the juice. Recalling an uncle's story of military training, the girl suggests they eat salt to retain water and surmises to her brother that they may spend some time in the desert. She remains stoic, but wary, while her brother is blissfully unaware of their situation, remaining entertained by the radio and his toys. Eventually, after becoming filthy and tired, they come upon a lone tree standing over a pool of water where parakeets flock and feast on fallen fruit. The boy puts on in his mouth and proclaims that it 'tastes lovely'. They wash in the water and the girl scolds her brother to take care of his clothes so they will last. When he asks if they are lost, the girl replies that they are not, trying to remain chipper. They sleep to the sounds of the radio as night animals stir around them.In the morning, the girl wakes to find that their water hole has dried up and the fruit has either been eaten or spoiled. The girl decides to remain where they are, hoping that the water will return. As they nap in the hot sun, the boy spots an aborigine youth (David Gulpilil) pursuing an animal for food. They make contact and the children attempt to communicate with the aborigine boy. However, he does not understand their language and merely stares at them with curiosity. The girl repeats their need for water but the word is incomprehensible to the aborigine. When her brother mimics drinking, the aborigine understands and shows them how to dig for water using a hollow tube to drink through. Assuming that he will lead them to civilization, the siblings accompany the aborigine, unaware that he is on a 'walkabout', a coming-of-age journey that every male aborigine youth must take alone in order to be initiated as an adult in his tribe.As they travel the Outback, the aborigine kills and harvests food for them, giving them all plenty to eat and drink. The move from the desert to greener pastures and forests where wildlife becomes plentiful. When the boy becomes sunburnt from going shirtless, the aborigine rubs pig fat on his back to alleviate the burn. While communication between them remains limited, the trio share food and play together, though cultural differences are evident; the boy attempts to share his toy soldiers with the aborigine, but he finds no use for them and tosses

SOLUTION: What does the Aboriginal boy hunt down ?

PROBLEM: The Web site for the Anxiety Disorders Association of America (ADAA) receives more than 5 million visits per month and thus represents a unique medium for the study of anxiety disorders. ADAA Web site users from October 2002 to January 2003 were invited to complete a survey oriented toward trauma history and psychiatric sequelae. A diagnostic approximation of posttraumatic stress disorder (PTSD) was based on responses to the Trauma Questionnaire, the Davidson Trauma Scale, and questions about impairment. The Connor-Davidson Resilience Scale was also used. Variables were tested for their association with PTSD. Among 1558 participants, 87% had a history of trauma, and 38% had current PTSD. The population was comprised predominantly of white middle-class women, half of whom were married. More than 90% were first-time users of the site. Factors associated with PTSD included death of, or harm to, a loved one; personal history of incest, rape, or physical abuse; lower age; lower income; unemployment; missed work; increased medical care; dissatisfaction with psychotropic medication; depressive symptoms; and lower resilience. In this selective convenience sample, there were high rates of traumatization and PTSD. The demographics of this group are similar to those seen in previously studied populations that had contacted the ADAA. Furthermore, the factors associated with PTSD were like those in many community surveys. The ADAA Web site has the opportunity to benefit large numbers of highly distressed individuals.

SOLUTION: Symptoms of which disorder are evaluated with the Davidson Trauma Scale?

PROBLEM: Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials. A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress. Compression squeezes rocks together, causing rocks to fold or fracture (break) (Figure 1.1). Compression is the most common stress at convergent plate boundaries. Stress caused these rocks to fracture. Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is called shear (Figure 1.2). Shear stress is the most common stress at transform plate boundaries. Shearing in rocks. The white quartz vein has been elongated by shear. When stress causes a material to change shape, it has undergone strain or deformation. Deformed rocks are common in geologically active areas. A rocks response to stress depends on the rock type, the surrounding temperature, the pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress. Rocks have three possible responses to increasing stress (illustrated in Figure 1.3): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks. Under what conditions do you think a rock is more likely to fracture? Is it more likely to break deep within Earths crust or at the surface? What if the stress applied is sharp rather than gradual? At the Earths surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically. Sudden stress, such as a hit with a hammer, is more likely to make a rock break. Stress applied over time often leads to plastic deformation. Click image to the left or use the URL below. URL:
