E-books, an online book retailer, has two operating departments—corporate sales and consumer sales—and two support departments—human resources and information systems. Each sales department conducts merchandising and marketing operations independently. E-books uses number of employees to allocate human resources costs and processing time to allocate information systems costs. The following data are available for September 2017:
|
Support Departments |
Operating Departments |

The company allocates the Human Resources Department cost using the budgeted number of employees in each department. The costs of Information systems department are allocated to other departments using the number of minutes of information processing time for those departments.
a) Allocate the costs of the support departments to the operating departments using the reciprocal cost allocation method

The different interpretations which were given for Human Resource Management produced two Schools of Thoughts – the Soft and the Hard Versions. They are considered as two main models of HRM. The soft version focuses on human’s side and the hard part on the job. One of the first explicit statements of the Human Resource Management concept was framed by the Michigan School of Thought under the leadership of Fombrun et al in 1984. The model was also known as the “Matching model”. This model also shows that there is a tight fit between the organization strategy, the organization structure and the Human Resource Management system. Fombrum et al have argued that in this model the practices of HRM is made up of the human resource cycle comprising of 4 generic processes that need to be performed in mostly all organisations. They are:
1) Selection,
(2) Appraisal,
(3) Rewards,
(4) Development.
Considering these four processes, describe clearly with examples how they are implemented and managed in organisations to justify that they are making full-use of HRM activities for their success and competitiveness. Substantiate your descriptions with examples. You can refer to any existing enterprise.

Traditionally, human resource management practices were developed and administered by the organization’s human resource department. Line managers/supervisors are now playing a major role in developing and implementing HRM practices.
Why do you think non-HR managers are becoming more involved and what do you see as the main benefits for more involvement in HR from managers and supervisors?

Epidemiologists study the occurrence and transmieeion
of human diseases on a global scale. this is no easy task since
pathogens, or disease-causing organisms are everywhere. it is
virtually impossible to avoid coming into contact with a
potentially pathogenic microorganism in the modern world.
INFLAMMATION: PLEASE provide background about a disease-causing
microbe. is it a virus, bacterium, etc.? what are the symptoms of
the disease.
Describe the impact of this microbe on human health. why would this
disease be of concern to epidemiologists? what is the prevalence of
the disease in the human population?
describe any treatments available for the disease. include
vaccinations and chemotherapeutic treatment options.
in your option, would the innate immune system or the adaptive
immune system be more effective at fighting off this
infection?
this must be written 800 to a 1000 words.

Discuss the Extinction Risks for Coral Reefs as a result
of Coral Bleaching.
Coral reef ecosystems around the globe are threatened by human
interferences and climate
change. This has led to many scientists conducting studies on
global coral reef ecosystems to gain
a better understanding of the cause and effects of coral reef
damage.
We will take four opportunities to engage in discussion on the
selective topic such as :origins,human impacts, biodiversity,
environmental factors and algal diversity . You will identify the
significant that associates the topic and overall
invertebrates.
Key connections:
Climate change; global warming, symbioses, diversity Important,
human impact, and coral reef conservation.
Important Questions:
Can it be reversed? Or can coral habitats be restored?
Examples of resources: Primary literature information.

Microbiology Final Assessment Preparation
Highlight the important concepts of microbe-human interaction in health and in infection and disease.
Outline and discuss the body’s immune system: 1st Line of Immunity, 2nd Line of Immunity and 3rd Line of Immunity (specific or acquired immunity).
Explain the phenotypic, genotypic, and immunologic methods to identify pathogens and diagnose infections.
Discuss in detail the structure and disease process of the pathogens associated with human disease including Gram (+) and Gram (-) cocci, Gram (+) and Gram (-) bacilli and miscellaneous bacterial pathogens.
Discuss in detail the structure and disease process of the pathogens associated with human disease including fungi, parasites, and viruses.
Discuss at least 3 important topics related to the course content for Modules 6-9 as a tool to prepare for the final assessment.

Erythromycin is an antibiotic used to treat bacterial infections, by binding in front of the A site on the 50S subunit of a ribosome.
Why is Erythromycin effective against bacterial infections while causing minimal side effects on human cells?
Group of answer choices
1Bacterial ribosomes are 80S; cytoplasmic ribosomes in eukaryotes are 70S (so the drug will only target the bacterial ribosome)
2.Bacterial ribosomes are 70S; cytoplasmic ribosomes in eukaryotes are 80S (so the drug will only target the bacterial ribosome)
3.Erythromycin targets both bacterial and human cell structures
4.Human cells do not have cell walls
Which of the following processes is directly inhibited by this drug?
Group of answer choices
replication
translation
transcription
horizontal gene transfer

The Buckaneer Clinic has two service departments (Human Resources and Information Resources) and two "production" departments (In-patient Treatment and Out-patient Treatment). The service departments service the "production" departments as well as each other, and studies have shown that Information Resources provides the greater amount of service. Which of the following allocations would occur if Buckaneer uses the direct method of cost allocation?
Multiple Choice
Information Resources cost would be allocated to In-patient Treatment.
Information Resources cost would be allocated to Human Resources.
Human Resources cost would be allocated to Information Resources.
In-patient Treatment cost would be allocated to Out-patient Treatment.
Out-patient Treatment cost would be allocated to Information Resources.
