A research associate working for Intragene Therapeutics prepares an investigative PCR reaction to screen human tissue samples for specific mutations. He uses 55 ng of genomic DNA from one tissue sample in a single PCR reaction, to amplify a 1,246 bp fragment. The PCR protocol requires a final concentration for two primers of 1.5 uM each, and a final concentration of 180 uM for dNTPs, in a total PCR reaction volume of 65 uL. During the PCR process, the fragment is amplified for 33 cycles. He quantifies the amount of PCR products to be 74 ng/uL.

Question: How many copies of the fragment are produced in his PCR reaction? Assume that the target sequence is present in only one copy in the genome, as in a haploid human genome.

Jane earns more money than Janet, despite the fact that they have the exact same level of human capital and are very similar workers, and work at the exact same job. In fact, the only noticeable difference between them is that Jane grew up in Gardinia and Janet grew up in Trackton.

You speak to their employer, who says "Most of my customers are from Gardinia, and there's an intense sports rivalry there, so a lot of them don't want to be helped by someone from Trackton. So I offered Janet a lower wage than Jane."

This is an example of wage differentials on the basis of...

Select one:

a. human capital

b. signaling

c. taste-based discrimination

d. statistical discrimination

e. unions

f. compensating differentials

Dear staff:

This is Yu.zhou. May anybody who is good at the Health Professionalism class and had read the book entitled "The Immortal Life of Henrietta Lacks" help me with the question below. I would like the questions be answered as one or several paragraphs. Thank you, sincerely.

Based on the book "The Immortal Life of Henrietta Lacks", answer the questions below:

Ownership of genetic material is still a vexed issue. Many human genes have been patented and a battle is currently being fought through the U.S. courts between doctors and a biotech company owning the patents for genes used in breast cancer research screening. What are your thoughts about research and patents in this now “profit making” industry? Is there an ethical way to create a finance structure for medical advancement that honors human contribution and why?

Many government programs (for example, controlling of hazardous pollutants in drinking water, improving nuclear power plant safety) are aimed to save human life as well as to reduce chronic illness, mortality and hospitalization. Given that government has several programs, how resources should be allocated among these programs depends on the value of human life. So an estimate of the value of life to society is necessary and such estimates are required by federal regulations for benefit-cost analysis.

Think about decisions made by medical personnel when they face shortage of Artificial Lung machines and PPE at hospitals in the U.S. Who gets to (stay alive and have a chance to survive) and who doesn't get one and dies?

So how is life to be valued? Simple answer -- life is priceless. But is it useful for decision making?

How do you think?

Foreign investors will be reluctant to invest in poor countries if their poverty is due to their poor human capital. Because a country lacks skilled workers, it will be difficult to use more advanced technology and machines. So the rate of return on the machine is very low and that explains why capital flows more to rich countries than to poor ones. Well-educated poor countries are more likely to have human resources flowing to rich ones. "Well-educated Indians transfer 14.4 times as much to the US as uneducated Indians," “the skilled would want to move to poor countries, because the skilled wage differential is actually in favor of the rich countries. An engineer in Bombay earns $2,300 per year; an engineer in New York earns $55,000 a year ”

One of the questions on a survey asked adults a series of questions on attitudes toward automation. The results showed that 2,973 out of 4,135 respondents are worried about a future in which robots and computers can do many human jobs; 2,774are worried about the development of algorithms that can evaluate and hire job candidates; and 2,236 are worried about the development of driverless vehicles. (Round your answers to four decimal places.)

(a)

Develop a point estimate of the proportion of respondents who are worried about a future in which robots and computer can do many human jobs.

(b)

Develop a point estimate of the proportion of respondents who are worried that the development of algorithms that can evaluate and hire job candidates.

(c)

Develop a point estimate of the proportion of respondents who are worried about the development of driverless vehicles.

Needs analysis focuses on thoroughly gathering, prioritising and documenting an organisation’s HR information requirements. The purpose of needs analysis is to collect and document information that is related to making changes connected to:
* The current system performance issues
* A new systems application and tasks
*And any opportunities perceived to benefit the business.
An effective needs analysis consists of five stages. You are the HR manager of Leo Enterprise. The organisation is embarking on a HR system migration in order to keep up with technology trends as well as providing an effective human resources department. The IT systems analyst requires your input on the Observation and Exploration stages of the Needs Analysis. Conduct stage 2 and 3 of the needs analysis process of the organisation’s human resources information requirements, to serve as necessary input for the subsequent design and implementation of the new HR Information System.

The length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with mean 262 days and standard deviation 20 days.

Use a normal z-table to answer all questions below. If not,your answers may be marked as incorrect due to rounding issues.

(a) What proportion of pregnancies last less than 270 days (about 9 months)?
(Use 4 decimal places)

(b) What proportion of pregnancies last between 240 and 270 days (roughly between 8 months and 9 months)?
(Use 4 decimal places)

(c) The longest 20% of pregnancies last  days or longer. (Round to an integer.)

(d) What are the quartiles of the distribution of lengths of human pregnancies?

Q1 = __ days (Round to an integer.)
Q3 = ___ days (Round to an integer.)

Monkey knockouts? ANDi is the first step on the path to developing a knockout monkey that could be a better animal model for studying diseases and their treatments. Genetically modified primates could potentially be used to study breast cancer, HIV, and any number of diseases. However, not everyone agrees that creating a knockout monkey should be a scientific goal. Some point out that mice, and even zebrafish, share the majority of human genes and have been used effectively in research. Others argue that a knockout monkey could present a threat to public health because a pathogen might leap from the study animals to the human population. Others are uncomfortable with the use of primates in any sort of research due to their close relationship to humans. What do you think? Should we press forward to develop a knockout monkey?
