Item Standardizing training performance to enhance California hazardous materials responder proficiency(2013)Regulatory agencies define target performance for capabilities of hazardous materials (HAZMAT) response agencies, but do not specify standardized proficiency for individuals. This study examines training requirements and performs an analysis of training methodologies in a sample of agencies in California. A survey garnered data on their analysis, design, development, implementation and evaluation of training programs. The results reveal perceived inconsistencies in proficiency across jurisdictions but none within responding agencies when compared to expected task performance requirements. Further research and guidance is needed on standardized proficiency as well as on the development of HAZMAT training programs across the state.Item Stability of urine ethyl glucuronide(2008)The detection of ethyl glucuronide (EtG) in urine samples is an important tool for monitoring the compliance of offenders on probation. As a non-volatile, water-soluble, direct metabolite of ethanol, it has become one of the fastest emerging biomarkers for proof of alcohol consumption. This investigation was conducted to: insure that urine samples positive for EtG remained stabile at room temperature for up to 10 days; to discover whether or not the type of alcohol consumed affects EtG stability; and finally, if EtG is spontaneously produced in negative samples that are stored at room temperature for 10 days. Subjects included 6 volunteers asked to consume mixed drinks, 6 volunteers asked to consume wine, 6 volunteers asked to consume beer, and 6 volunteers asked to abstain from alcohol consumption for 7 days. The last 6 volunteers were broken into 2 groups. One group of 3 was asked to avoid any products containing ethyl alcohol, such as vanilla, certain mouthwashes, soaps, and deodorants. The other 3 were allowed to continue use of these products. All 24 volunteers provided 80mLs of midstream urine to be monitored, through duplicate quantitative testing by GCMS, for a 10 day period while being stored at room temperature.Item Strategies of design and management of stormwater for Carnation Avenue the city of Imperial Beach, California(2004)Uncontrolled storm water and surface runoff can cause significant environment damage. Flooding is 6 obvious example of a storm water problem, with the accompanying loss of property and some times, human life. Even when the amount of storm water runoff is not enough to be characterized as a flood, water pollution problems can be severe, particularly from soil erosion and sediments. Storm water runoff is a major non point source of water pollutants, including fertilizers, pesticides, oil, organic and other substances. Land development and urbanization increases the frequency and severity of these problems. Technical personnel involved in the design and construction of new residential, commercial, or industrial land use facilities must take stapes to reduce the harmful environmental impacts of storm water runoff.Item The study of how to improve the employees' work efficiency at SDPW(2012)The aim of this research is to find factors which impact employees’ working production and efficiency at Sony Digital Products (Wuxi) Co. Ltd (SDPW), and provide recommendations to improve worker production efficiency. In the last thirteen months, the researchers conducted extensive research into project management knowledge. Considering the various factors that affect work efficiency, the two research questions that are answered in this study: What are the factors that impact employee’s working efficiency at SDPW? Among these factors, which are the three major factors that have maximum influence? Thirty four managers and engineers from SDPW completed a survey that measured whether the implementation of a new time management strategy at SDPW is necessary to improve work production and efficiency. The research team analyzed the results of this work efficiency inspection survey conducted at SDPW to rank the major factors which seriously impacted employees’ productivity and efficiency. For analyzing the degree of influence of each factor, the researchers used three useful index formulas called importance index, frequent index, and severity index respectively. The results of the survey showed that early morning meetings, lack of personal planning and scheduling, and using the computer to do personal things were the three major factors at SDPW where works waste their time. From this research, findings indicate that time management is a precisely dynamic process that is both unique and complex, depending on a number of factors such as the personal and company factors. Therefore, some new time management strategies are required to be conducted at SDPW for improving work efficiency.Item State gun laws and firearm homicide rates across age groups(2016)The primary goal of study was to gain insight into the relationship between state gun laws and firearm homicide rates. To do this, the Brady Campaign's Annual State Scorecard was used to assign a score for each state based on the number of gun control laws. These scores were then matched to each state's firearm homicide rate to determine a correlation coefficient. The correlation between the two variables was found to be very weak. The same analysis was then performed five times with the homicide victim population broken into five separate groups based on victim age. The results of these five analyses demonstrated that as victim age increased, a stronger correlation between the two variables can be observed.
