1. Illustrate and explain the Human Capital approach to education decisions. How does the Signalling approach fundamentally differ from the Human Capital approach?
2. Explain and illustrate two methods that unions can use to raise the wage rate for their members.

3. Classical economic theory treats unions as monopolies that create inefficiencies in the economy. Explain and illustrate how these inefficiencies are created in both the labour and product markets.

4. Explain and illustrate the cross sector effects that may occur due to unions.
   

5. Explain and illustrate how unions may increase efficiencies in monopsonistic markets.

A competing commercial effort to sequence the human genome was initiated by the company Celera in 1997. How was their approach different from the Human Genome Project?

• A. Libraries of individual chromosomes were generated and overlapping clones were isolated before sequencing.
• B. They used sequence tagged sites (STS) and expression sequence tags (EST) to order contigs prior to sequencing.
• C. They sequenced the entire genome from one female donor.
• D. They generated overlapping clones from YAC and BAC libraries that were identified by hybridization and organized into long contiguous stretches called contigs.
• E. They used a whole-genome shotgun sequencing method that eliminates the step of assembling a physical map of the genome.

Even though there are cases of Down syndrome that are more severe than others, why do we treat all people born with Down syndrome as if they are the same as each other? Why is this question Important to you as a member of society? Detail the major developments in social science thinking that drive questions regarding the individual. Explain how finding the answer to the question might impact other around you. Detail the major developments in social science thinking that drive questions regarding studying others. Explain why studying human behavior and identity is a valuable human endeavor. Detail the major developments in social science thinking that support the study of advancement of the social sciences as necessary and valuable.

The length of human pregnancies is approximately normal distributed with mean =266 days and Standard Deviation = 16 days ( 20 points ) . Exercise 8.1 What is the probability a randomly selected pregnancy lasts less than 260 days? Suppose a random sample of 20 pregnancies is obtained. Describe the sample distribution the sampling distribution of sample mean of human pregnancies. What is the probability that a random sample of 20 pregnancies has a mean gestation period of 260 days or less? What is probability that a random sample of 50 pregnancies has a mean gestation period of 260 days or less? What is the probability a random sample of size 15 will have a mean gestation period within 10 days of the mean?

write an argumentative essay consisting of a solid,
clearly articulated thesis statement, reasons and evidence supporting the thesis statement, and a logical

As technology evolves and new machines with new abilities are being invented, human beings are
becoming used to stagnancy and a labor-free lifestyle. They rely on these gadgets and machines more
than they rely on their own abilities and capabilities. As a result, human talent is gradually
disappearing and machine talent is taking its place. Do you agree or disagree with this statement?
Support your stance with logical reasons, evidence and data.

1. a) State the Wolff’s law of the transformation of bone. b) What is the fundamental idea in the trajectorial theory of bone structure? c) Discuss in detail the composition and structure of bone explaining why the different bone tissues are organized differently. d) Explain why the bones of the human body are stronger in resisting compression than tension and shear. e) In the human femur, bone tissue is strongest in resisting compressive force, approximately half as strong in resisting tensile force, and only about one-fifth as strong in resisting shear force. If a tensile force of 8000N is sufficient to produce a fracture, how much compressive force will produce a fracture? How much shear force will produce a fracture?

Alex, who is married and the father of four, is age 45 and expect to work to age 65. He earns $70,000 per year and expects annual salary increases of 5%. Alex expects inflation to be 4% over his working life. His personal consumption is earl to 10% of after tax earnings, and his combined federal and state marginal tax bracket is 20%. Human Life Approach

(a) calculate the family’s share of earnings

(b) Calculate work life expectancy

(c) calculate the future value of the family’s share of earnings (FSE) over Alex’s work life expectancy (WLE)

(d) determine the human life value (HLV)

Financial Needs Approach

Human Resource Management (HRM) takes a strategic approach in developing and maintaining a qualified workforce to gain a competitive advantage. The role of a Human Resource Manager in the strategic process is to focus on the specific areas that will contribute to the overall effectiveness of the organization. If you were an HR Manager, on which would you focus? Give a rationale for your choice.

• Knowledge workers: Seeking individuals who have the skillset to perform the specific functions of the job.
• Financial Crisis: Ensuring the organization can meet financial obligations when the external environment (economy, laws) negatively affects the organization and prevents it from meeting forecasts for annual sales.
• Ethically and socially responsible to the needs of society.
• Work life balance for all employees.
