Research Methods

For this assignment, you will define the research objectives and develop the research questions and hypotheses to set the stage for the Sun Coast Remediation research project.(SeeAttached)

You will utilize this

template

(SeeAttached) to complete the Unit II assignment.

Be sure to include the following sections in your submission, and remember to use APA-formatted section headings and subheadings.

• Introduction
• Research problems
• Research objectives: Refer to the Introduction and Statement of Problems sections provided in the Unit II Assignment Template to make explicit statements as to the objectives of this study. For example, “One objective of this research study is to determine the direction (either positive or negative) and the strength of relationships between ABC Company’s various consumer promotions and sales revenue. This objective is intended to determine which promotions may be more effective and strategically important.” Research objectives should be discussed for each problem identified.
• Research questions and hypotheses: Provide research questions and null and alternative hypotheses that align with the research objectives and problems. For example:

  RQ1: What is the relationship between Promotion 1 and sales revenue?

  Ho1 (null hypothesis): There is no statistically significant correlation between Promotion 1 (independent variable) and sales revenue (dependent variable).
  Ha1 (alternative hypothesis): There is a statistically significant correlation between Promotion 1 and sales revenue.

  RQ2: What is the relationship between Promotion 2 and sales revenue?

  Ho2: There is no statistically significant correlation between Promotion 2 and sales revenue.
  Ha2: There is a statistically significant correlation between Promotion 2 and sales revenue.

  RQ3: Are there differences in return on investment (ROI) between the various promotions?

  Ho3: There are no statistically significant differences in ROI between Promotion 1 and Promotion 2.
  Ha3: There are statistically significant differences in ROI between Promotion 1 and Promotion 2.

The title and reference pages do not count toward the page requirement for this assignment. This assignment should be a minimum of two pages in length, follow APA-style formatting and guidelines, and use references and citations as necessary.

Sun Coast Remediation Literature Review

According to Akintoye et al. (2016), the long-term exposure to particulate matter such as soot, fly ash, asbestos, pollen, smog, mold spores, bacteria, and virus found in polluted areas or could cause health issues. The nature of work that the Sun Coast employees do is to clean areas contaminated by the above mentioned toxic material, which means that they are exposed to them in their daily activities. Exposure to this particulate matter could cause lung cancer cardiopulmonary mortality. Particulate matter that the PM of below 10 microns is very harmful as they can be inhaled, causing complications to the respiratory system, which is one of the risk factors facing the Sun Coast employees.

High levels of lead exposure on human beings could harm their health. The employees of Sun Coast carry out contracts with an organization that aims at remediating sites that have been contaminated by Lead, which means that they are exposed to the substance for an extended period at high levels. According to Fenga et al. (2017), occupational exposure to lead can cause immunological effects on human beings as high levels of Lead present in the human system or blood affects how the body’s immune system responds to various factors and diseases causing organisms. The Effect of Lead on the immune system makes the individuals prone to allergies, infectious diseases, reproductive system, cardiovascular and nervous system problems that threaten their lives.

Gan, W. Q., & Mannino, D. M. (2018). Occupational noise exposure, bilateral high-frequency hearing loss, and blood pressure. Journal of occupational and environmental medicine, 60(5), 462-468.

According to Gan & Mannino (2018), exposure to occupational noise could lead to hearing loss and heightened blood pressure. Sun Coast render to their clients involves using the heavy machine, which makes the working environment noisy for the employees. Gan & Mannino (2018) states that a working environment with noise levels exceeding 120 decibels (dB) could harm the people working there, and with time it would cause them to lose their hearing ability. The high level of noise exposure that the Sun Coast employees are exposed to could also heighten diastolic blood pressure. The high level of noise and vibrations caused by the Sun Coast employees’ heavy equipment causes an increase in heart rate, elevating blood pressure that might lead to hypertension, threatening their lives.

Inconsistency in the reruns on investment is a massive problem in businesses where investors do not get the expected returns of how much resources they have invested in a business. Sun Coast has a problem with the inconsistency of return of profit from its different business lines, which can be caused by the dedication of energy and resources to some business lines and not the others and the competition in the field of operation. When a company with different lines invests a lot in some lines, they tend to give high returns than those with little resources. The competition in the field might also affect how some business lines perform due to many competitors reducing the chances of some lines securing a contract that will bring high returns.

The article Using Beta Coefficients to Impute Missing Correlations in Meta-Analysis Research states that meta-analysis is becoming a widely used research strategy in the contemporary world. The best part about this research methodology is that it allows researchers to dig up for missing data in research, which results in more accurate results. It is a challenge when using meta-analysis if the preliminary study done on a topic does not report a correlation between factors and variables of interest. The article will enable the collection of sufficient data on the issue with sun coast, which will allow a conclusive and all-inclusive result that will make the results reached are viable.

Employees need to be thoroughly trained and tested before they are sent to the field, especially in organizations such as the Sun Coast, where they deal with life-threatening toxic materials. Training of new employees is vital to ensure that they have the skills and the knowledge of carrying out their duties and operations in the safest way possible (Sorensen et al., 2018). Enhanced employees’ training ensures that they become more productive and prevents injuries and accidents in their place of work. Although new employees’ training might be costly and time-consuming, it is worth compared to the effects that might come as a result of not training employees.
