Input: Consider Input: Does everyone want a challenging job? In spite of all the attention focused by the media, academicians, and social scientists on human potential and the needs of individuals, there is no evidence to support that the vast majority of workers want challenging jobs. Some individuals prefer highly complex and challenging jobs; others develop in simple, routine work. The individual-difference variable that seems to gain the greatest support for explaining who prefers a challenging job and who doesn't is the strength of an individual's needs for personal growth and self-direction at work. Individuals with these higher-order growth needs are more responsive for challenging work. What percentage of ordinary workers actually desire higher-order need satisfactions and will respond positively to challenging jobs? No current data is available, but a study from the 1970s estimated the figure at about 15%. Even after adjusting for changing work attitudes and the growth in white-collar jobs, it seems unlikely that the number today exceeds 40%. The strongest voice advocating challenging jobs has not been workers--it's been professors, social science researchers, and media people. Professors, researchers, and journalists undoubtedly made their career choices, to some degree, because they wanted jobs that gave them autonomy, recognition and challenge. That, of course, is their choice. But for them, to force their needs onto the workforce in general is presumptuous . Not every employee is looking for a challenging job. Many workers meet their higher-order need off the job. There are 168 hours in every individual's week. Work rarely consumes more than 30% of this time. That leaves considerable opportunities, even for individuals with strong growth needs, to find higher-order need satisfaction outside the workplace. So don't feel you have a responsibility to create challenging jobs for all your employees. For many people, work is something that will never excite or challenge them. And they don't expect to find their growth opportunities at work. Work is merely something they have to do to pay their bills. They can find challenges outside of work on the golf course, fishing, at their local pub, with their friends in social clubs, with their family, and the like.

Output: What makes people choose challenging jobs?


Input: Consider Input: Almost all surfaces reflect some of the light that strikes them. The still water of the lake in Figure 22.9 reflects almost all of the light that strikes it. The reflected light forms an image of nearby objects. An image is a copy of an object that is formed by reflected or refracted light. If a surface is extremely smooth, like very still water, then an image formed by reflection is sharp and clear. This is called regular reflection. If the surface is even slightly rough, an image may not form, or if there is an image, it is blurry or fuzzy. This is called diffuse reflection. Both types of reflection are represented in Figure 22.10. You can also see animations of both types of reflection at this URL: [Link] In Figure 22.10, the waves of light are represented by arrows called rays. Rays that strike the surface are referred to as incident rays, and rays that reflect off the surface are known as reflected rays. In regular reflection, all the rays are reflected in the same direction. This explains why regular reflection forms a clear image. In diffuse reflection, in contrast, the rays are reflected in many different directions. This is why diffuse reflection forms, at best, a blurry image. One thing is true of both regular and diffuse reflection. The angle at which the reflected rays bounce off the surface is equal to the angle at which the incident rays strike the surface. This is the law of reflection, and it applies to the reflection of all light. The law is illustrated in Figure 22.11 and in the animation at this URL: Mirrors are usually made of glass with a shiny metal backing that reflects all the light that strikes it. Mirrors may have flat or curved surfaces. The shape of a mirrors surface determines the type of image the mirror forms. For example, the image may be real or virtual. A real image forms in front of a mirror where reflected light rays actually meet. It is a true image that could be projected on a screen. A virtual image appears to be on the other side of the mirror. Of course, reflected rays dont actually go behind a mirror, so a virtual image doesnt really exist. It just appears to exist to the human eye and brain. Most mirrors are plane mirrors. A plane mirror has a flat reflective surface and forms only virtual images. The image formed by a plane mirror is also life sized. But something is different about the image compared with the real object in front of the mirror. Left and right are reversed. Look at the man shaving in Figure 22.12. He is using his right hand to hold the razor, but his image appears to be holding the razor in the left hand. Almost all plane mirrors reverse left and right in this way. Some mirrors have a curved rather than flat surface. Curved mirrors can be concave or convex. A concave mirror is shaped like the inside of a bowl. This type of mirror forms either real or virtual images, depending on where the object is placed relative to the focal point. The focal point is the point in front of the mirror where the reflected rays intersect. You can see how concave mirrors form images in Figure 22.13 and in the interactive animation at the URL below. The animation allows you to move an object to see how its position affects the image. Concave mirrors are used behind car headlights. They focus the light and make it brighter. They are also used in some telescopes. The other type of curved mirror, a convex mirror, is shaped like the outside of a bowl. This type of mirror forms only virtual images. The image is always right-side up and smaller than the actual object, which makes the object appear farther away than it really is. You can see how a convex mirror forms an image in Figure 22.14 and in the animation at the URL below. Because of their shape, convex mirrors can gather and reflect light from a wide area. This is why they are used as side mirrors on cars. They give the driver a wider view of the area around the vehicle

Output: Concave mirrors are used


Input: Consider Input: Prologue: (narrated by Orson Welles) A small airplane with no one on board was flying along the Mediterranean coast near Barcelona . . . Opening shot shows an empty airplane in flight.Credits roll.At night, between the containers on a Naples pier, first we see a man running, then another, staggering, (Gregoire Aslan), who falls and we see a knife plunged on his back. Guy Van Stratten (Robert Arden) and his girlfriend Mily (Patricia Medina) happen upon the wounded man, and at once offer to stay with him and call for help. The dying man says no, no police, as I am dying anyway, in thanks for being good to me, listen, before I die I will give you some names that are worth millions. Find Gregory Arkadin, tell him you know about me, Bracco, and also about Sophie. In the confusion and noise of arriving police, Sophie's last name is garbled as Bracco dies.Guy is arrested for tobacco smuggling and put in prison for three months. Upon his release, he and Mily resolve to find out why that combination of names is valuable.Gregory Arkadin (Orson Welles) is a multimillionaire business magnate whose whereabouts are known, so Guy and Mily proceed to Cannes, but Arkadin has an enormous staff of bodyguards in charge of keeping riffraff away, so Guy can't get to him. Guy gets lucky as someone points out Arkadin's pretty daughter Raina (Paola Mori) to him. As he approaches, she is talking to her constant companion, the Marquess of Rutleigh (Jack Watling) and he says he is afraid to meet her father. Guy politely interrupts the conversation saying he would love to meet her father, and his daring strikes a chord with her, although she rebuffs his advances and warns that she is constantly watched by a large team of her father's employees.Guy has a conversation with Mily, telling her he will follow Raina and make advances to her in an attempt to get to Arkadin. Mily is a voluptuous cabaret entertainer who finds gigs easily, so she will try to become an entertainer for Arkadin, who throws big parties all the time.Guy keeps tailing Raina, finds out she will be driving to Spain, and persists in talking to her until she lets him ride along. On the ride, he is charming and she begins to fall for him.At their destination [Segovia], where Arkadin resides in the spectacular castle [the Alcazar], Guy manages to continue courting Raina while seeing the sights and observing a night parade of black-hooded men doing penance. As he kisses her and she warns that her father will destroy him if he is proved a fortune seeker, he vows he will never ever ask her to marry him. This enhances his attractiveness to Raina.Mily, meantime, sees enough that she feels jealous. If Guy is trying for a relationship with Raina, she will try for a relationship with Arkadin himself.Soon after at a masquerade ball at the castle, Guy enters as a guest and Mily has wangled a singing gig. As Guy enters, the camera follows him and the scale and magnificence of the party are a shocking display of wealth.Guy finally meets the mysterious billionaire Gregory Arkadin, and after a few remarks Arkadin leads him into Raina's cavernous bedroom to talk. He tells Guy he loves his daughter intensely and will do anything to protect Raina from unscrupulous, shady suitors. He shows Guy a dossier on his life, labeled Confidential Report, where Guy's many previous run-ins with the law and other unflattering facts are detailed. Guy is not intimidated but challenges Arkadin instead, claiming that if someone were to investigate Arkadin in a similar way, plenty of dirt would show up, and he himself would not look good.After an instant of reflection, Arkadin offers Guy a deal, that he investigate Arkadin's past and prepare a confidential report on him. Arkadin claims he had amnesia and knows nothing about his own life up to the time when he found himself wandering in Zurich during the winter of 1927 carrying a briefcase with 200,000 Swiss Francs. After some
