UNIT II SCHOLARLY ACTIVITY 2
Abstract
In this scholarly activity, as the director of Sun Coast for their safety and health department, I
will be identifying six research problems, objectives and questions (with one null hypothesis and
one alternative hypothesis per question). These will be used as part of the final research product
to determine the needed implementation measures I am being asked to develop as result of the
research.
Key Words: Research, Problem, Objective, Questions, Hypothesis, Null, Alternative.

Unit II Scholarly Activity
Introduction
As the new director for safety and health of Sun Coast, I am expected to develop and
research questions and hypotheses that will assist in the implementation of measures that will
meet business strategic goals such as reducing the costs associated with long-term litigation from
injuries and illness related to employment and the nature of our services.
The following business problems were identified by the leadership of Sun Coast:
Particulate Matter, Safety Training Effectiveness, Sound Level Exposure, New Employee
Training, Lead Exposure and Return on Investment. These problems are the priority of Sun Coast
and will require and the use of quantitative research data available to determine what will be my
best course of action recommendations.
Research Problems
Six business problems were identified:
Particulate Matter (PM)
There is a concern that job-site particle pollution is adversely impacting employee health.
Although respirators are required in certain environments, PM varies in size depending on the
project and job site. PM that is between 10 and 2.5 microns can float in the air for minutes to
hours (e.g., asbestos, mold spores, pollen, cement dust, fly ash), while PM that is less than 2.5
microns can float in the air for hours to weeks (e.g. bacteria, viruses, oil smoke, smog, soot). Due
to the smaller size of PM that is less than 2.5 microns, it is potentially more harmful than PM
that is between 10 and 2.5 since the conditions are more suitable for inhalation. PM that is less
than 2.5 is also able to be inhaled into the deeper regions of the lungs, potentially causing more
deleterious health effects. It would be helpful to understand if there is a relationship between PM

size and employee health. PM air quality data have been collected from 103 job sites, which is
recorded in microns. Data are also available for average annual sick days per employee per job-
site.
