Super, Osborne, Walsh, Brown, and Niles (1992) indicated that the life-career rainbow is the “development and unfolding of the life career of a person from birth until death.” Holland utilized personality trait theory to identify six types of individuals on the basis of their vocational interests. In high school, we are tested and counseled on potential career and college prospects. We even attend college with a career goal in mind. Interest in a particular career may not be the same as entering that type of career field. There are many factors that influence career choice and continuing in that career.

  • Search the Internet for more information on the life-career rainbow and explain how it may fit into the lifespan perspective of adult development. On the basis of your personal observations and experiences, describe why Super’s life-span theory of career development may or may not be accurate.
  • Describe Holland’s personality types. Explain how his theory is used to help individuals find their vocational interests. Using specific examples, describe the strengths and weaknesses of the theory.
  • Explain the idea that throughout adult life, an individual may often be defined by his or her career (doctor, lawyer, store manager, nurse, etc.). Describe, using your personal observations and experiences, how an individual’s career choice may affect him or her throughout life.

YOU BE THE CONSULTANT – Snow and Soda: A Profitable MixThere is an unlimited amount of useful knowledge and information to gain from any company in any industry. The Crowley family has proved that many times over by borrowing techniques used in their bottling plant (Polar Beverages), applying those to their ski area (Wachusett Mountain), and vice versa.A key factor for the success of both operations is filling unused capacity. An hour of unused or inefficient production time in the bottling plant has the same effect as an hour of unused or inefficient time on the ski slopes. The ski area was able to fill its idle capacity by targeting a number of diversified markets that use the slopes at different times of the day and week. The bottling plant was able to fill its idle capacity by reshaping the size of its bottles to better pack trucks.On the surface, companies in different industries may appear to have little in common. The entrepreneur recognizes the opportunities of technology transfer–applying the lessons learned in one business and applying those same principles to assorted others.————————————————————————————————Q1.

What is the difference between statistical significance and practical significance? Why is statistical significance not necessarily of practical important difference to a business decision? Provide an example of this.I need a comment (verify solution) in 25-75 words from the response given below from the question listed above.”Statistical significance refers to the unlikelihood that mean differences observed in the sample have occurred due to sampling error. Practical significance looks at whether the difference is large enough to be of value in a practical sense.” Statistical refers to the null hypothesis where as the practical lays out the calculations and conclusions. Some reasons why statistical is not of the most importance is because “Tests of statistical significance rarely tell us about the importance of a research result and effect size tells us about magnitude of difference, which is important, but it is difficult for practice-oriented practitioners to comprehend.” If a sample is taken of such few numbers, it will not provide any real evidence towards whether the null hypothesis is really correct or not. There needs to be a greater amount of ‘n’ for the evidence to be practical. The link provided helps at spelling it out more. Still a little confused with this chapter but this may help some of you.
