“Adobe Consulting Services (ACS), a provider of HR software application systems, prides itself on the variety of benefits it offers employees. In addition to healthcare, pension, and vacation benefits, the company also offers an attractive family-friendly benefits package including flexible schedules, child and elder care assistance, counseling services, adoption assistance, and extended parental leave. Unfortunately, in recent months, the company’s progressive work/life policy has experienced a backlash from several employees, as the following case illustrates.　 In March 2002, Teresa Wheatly was hired by Adobe as a software accounts manager. With excellent administrative and technical skills, plus four years of experience at Adaptable Software, Adobe’s main competitor, Teresa became a valued addition to the company’s marketing team. As a single mother with two grade-school children. Teresa received permission to take Fridays off. She was also allowed to leave work early or come in late to meet the demands of her children. Teresa is one of eleven software account managers at Adobe.The problem for Adobe, and particularly Janis Blancero, director of marketing, began in the fall of 2002. On September 15, Dorothy McShee, citing “personal reasons”-which she refused to discuss-requested a four-day work-week for which she was wiring to take a 20 percent cut in pay. When Dorothy asked for the reduce work schedule, she sarcastically quipped, “1 hope I don’t have to have kids to get this time off.” On October 3, Juan Batista, a world-class marathon runner, requested a flexible work hours arrangement in order to accommodate his morning and afternoon training schedule, Juan is registered to run the London, England, marathon in May 2003. Just prior to Juan’s request, Susan Woolf asked for, and was granted, an extended maternity leave to begin after the birth of her first child in December. if these unex-peeled requests were not enough, Blancero has heard comments from senior account managers about how some employees seem to get “special privileges,” while the managers work long hours that often require them to meet around-the-clock customer demands. Janis has adequate reason to believe that there is hidden tension over the company’s flexible work hours program. Currently, Adobe has no formal policy on flexible schedules. Furthermore, with the company’s growth in business combined with the increasing workload of software account managers and the constant service demands of some customers, Biancero realizes that she simply cannot grant all the time-off requests of her employees.QUESTIONS1. Do managers like Janis Blancero face a more complicated decision when evaluating the personal requests of employees versus evaluating employees’ individual work performance? Explain.2. a. Should Adobe establish a policy for granting flexible work schedules? Explain.b. If you answered yes, what might that policy contain?3. If you were tunis Blancero, how would you resolve this dilemma? Explain. ”

1. For radio transmission in free space, signal power is reduced in proportion to the square ofthe distance from the source, where as in wire transmission, the attenuation is a fixednumber of dB per kilometer. The following table is used to show the dB reduction relative tosome reference for free space radio and uniform wire. Fill in the missing numbers tocomplete the table.2 . What is the difference between QPSK and offset QPSK?3. A modified NRZ code known as enhanced-NRZ (E-NRZ) is sometimes used for highdensity magnetic tape recording. E-NRZ encoding entails separating the NRZ-L data stream into7-bit words; inverting bits 2,3, 6,and 7; and adding one parity bit to each word. The parity bit ischosen to make the total number of 1s in the 8-bit word an odd count. What are the advantages ofE-NRZ over NRZ-L? Any disadvantages?4.5.6 For the bit stream 01001110, sketch the waveforms for each of the codes of table 5.2. Assume that the signal level for the preceding bit for NRZI was high; the most recent preceding 1 bit (AMI) has a negative voltage; and the most recent preceeding 0 bit (pseudoternary) has a negative voltage.5. the voice signal must be used to modulate a higher (carrier) frequency for which the naturalantenna size is smaller/a. What is the length of an antenna one-half wavelength long for sending radio at 300Hz?b. An alternative is to use a modulation scheme for transmitting the voice signal bymodulating a carrier frequency, so that the bandwidth of the signal is a narrow bandcentered on the carrier frequency. Suppose we would like a half-wave antenna tohave a length of 1 m. What carrier frequency would we use?6. For radio transmission in free space, signal power is reduced in proportion to the square of the distance from the source, where as in wire transmission, the attenuation is a fixed number of dB per kilometer. The following table is used to show the dB reduction relative to some reference for free space radio and uniform wire. Fill in the missing numbers to complete the table.7. Suppose a ray of visible light passes from the atmosphere into water at an angle to the horizontal of 30o. What is the angle of the ray in the water? Note: At standard atmospheric conditions at the earth’s surface, a reasonable value for the refractive index is 1.0003. typical value of refractive index is 4/3
