The Effect of Trauma on the Mental Health of Forensic Scientists

The purpose of this thesis was to determine the existence of any correlation between forensic scientists experiencing trauma and levels of mental health disorders, such as anxiety, depression, and PTSD. A survey created in Qualtrics with demographic questions and measurement questionnaires for each mental health disorder was utilized for this study. While there was little statistical analysis due to a small sample size, results showed a correlation between experiencing anxiety and PTSD. Research also illustrated that there were no respondents that reported having no level of the mental health disorders listed. Keywords: forensic scientist, trauma, mental health, anxiety, depression, PTS

Water, Waste and Quality Management During Preparation and Processing of Vegetables

The research was designed to test and/or develop new systems of washing, peeling and blanching, develop methods of utilization of solid wastes, and find ways to reduce wastestrength of effluent without affecting quality of vegetables for processing. The highest wastestrength of effluent from vegetable processing in the region was found in plants that were canning Irish potatoes, dry beans and hominy. The high volumes of water used for washing spinach and leafy greens and the physical damage to the washed product is one of the major problems. Repetitive washing of spinach in the same water did not affect quality as long as there was sufficient rinsing after the second wash. The levels of COD, TSS, TS, SS, PO4 and NO3 did not build up to prohibitive levels by the reuse of water as long as adequate make-up water was added. Steam blanching, which leaches out much less soluble constituents, can be substituted for water blanching by using appropriate times and temperature for different vegetables. The greater retention of nutrients in steam blanched vegetables was demonstrated in different vegetables grown and processed under different conditions. Data from research on the canning of dry beans indicated that the high wastestrength can be reduced by shortening the soaking time, controlling the temperature of soaking and processing without blanching without changing the quality appreciably. It appears that the present method of hominy preparation and processing can be altered to reduce pollution. By dipping corn in 10% lye solution, followed by heating and scrubbing, corn can be peeled and bleached efficiently. Most of the heavy solid waste can be isolated before the final rinse of the peeled corn. The prototype leafy greens washing system decreased the use of water by 70% on spinach, turnip greens and mustard. Water quality data showed that wastestrength of the effluent from washing was reduced over 50%, as compared to industrial washers, primarily due to less physical breakage. Less nutrients were leached out in greens washed by the experimental washer than the industrial washer. High alkalinity solid wastes from peeling Irish and sweet potatoes can be fermented and stored as long as 9 months without any great change in carbohydrates and total dry matter. There was an increase in sugar content and a decrease in starch content during fermentation. The quality of the sweet potato waste appeared to be excellent after storage when mold inhibitor was sprayed on vats. Irish potato waste storage created more odor problems unless the fermentation temperature was controlled at 25 to 30°C

Factors Affecting the Removal of Suspended and Dissolved Solids in High Strength Wastewater from Vegetable Processing

Fifty or more individual factorial experiments were designed to study the effectiveness of physical-chemical and micro-biological treatments in removal of suspended and dissolved solids in effluent from potatoes, hominy, dry beans and other vegetables. The wastewaters were obtained from local processing plants and treated with 3 to 5 inorganic salts, 13 polymers, and 3 or more pH levels during 12 months. Also, selected strains of yeast and fungi were used to assimilate the effluent. Individual inorganic salts were more effective on a certain vegetable effluent than others. Polymers (anionic and cationic) were more effective in coagulating suspended solids in combination with salts than either alone. Different polymers and concentrations of polymers in combination with salts were required for each effluent tested. Saccharonyces fibuliger was the most effective yeast for reducing total solids and chemical oxygen demand in potatoes. Actively fermenting systems were capable of 90% or more reduction after centrifugation. The fungi Neurospora sitophila and Trichoderma viride assimilated the total and dissolved solids more rapidly in effluents from potato and hominy processing than any of the other fungi studied

Hit Me with your Best Shot: A Critical Analysis of the Resistance to Vaccine Utilization

Vaccines have provided humans protection from infectious diseases for centuries, yet the vaccination rate in the United States fails to come near one-hundred percent, allowing vaccine-preventable diseases to re-emerge in communities across the nation. Vaccines have proven to be a safe and effective method in preventing the spread of infectious disease, but vaccine resistance remains high due to false information perpetuated by anti-vaxxers, greatly impacting the vaccination rate in our country. This thesis, by means of a literature review, provides a critical analysis the resistance to vaccine utilization in the United States to determine what policy recommendations and interventions can be made to reduce the resistance to vaccines and increase the vaccination rate in our country. Vaccine hesitancy has been around ever since the creation of the first vaccine and as the years went on, the modern anti-vaxx movement gained ground, voicing concerns over the ingredients in vaccines, the number of vaccines children receive in their first year, and the belief of the myth that vaccines cause autism. Even after medical science and years of research have validated the safety of vaccines and have shown no link to autism, vaccine hesitancy is still an issue as anti-vaxxers push to receive exemptions for medical, religious or philosophical reasons. Several states offer these types of exemptions, furthering the low vaccination rates in the United States and putting citizens’ health and safety at risk. The findings of the critical analysis were comparable to the literature review: compulsory vaccine laws have proven to be a successful solution to increase vaccination rates; however, these laws are left up to the states, allowing many individuals to go unvaccinated as only Mississippi, West Virginia, and California do not allow religious and philosophical exemptions. In order to address the low vaccination rates in the United States, policy interventions must be made through the states, the federal government, health care providers, and community and government-based organizations to increase the vaccination rate in our country through measures intended to increase vaccine compliance. Without these policy interventions, our nation and our world will never be free from the threat of vaccine-preventable infectious diseases

Femtosecond photoelectron and photoion spectrometer with vacuum ultraviolet probe pulses

We describe a setup to study ultrafast dynamics in gas-phase molecules using time-resolved photoelectron and photoion spectroscopy. The vacuum ultraviolet (VUV) probe pulses are generated via strong field high-order harmonic generation from infrared femtosecond laser pulses. The band pass characteristic in transmission of thin indium (In) metal foil is exploited to isolate the $9^{\text{th}}$ harmonic of the 800 nm fundamental (H9, 14 eV, 89 nm) from all other high harmonics. The $9^{\text{th}}$ harmonic is obtained with high conversion efficiencies and has sufficient photon energy to access the complete set of valence electron levels in most molecules. The setup also allows for direct comparison of VUV single-photon probe with 800 nm multi-photon probe without influencing the delay of excitation and probe pulse or the beam geometry. We use a magnetic bottle spectrometer with high collection efficiency for electrons, serving at the same time as a time of flight spectrometer for ions. Characterization measurements on Xe reveal the spectral width of H9 to be $190\pm60$ meV and a photon flux of $\sim1\cdot10^{7}$ photons/pulse after spectral filtering. As a first application, we investigate the S$_1$ excitation of perylene using time-resolved ion spectra obtained with multi-photon probing and time-resolved electron spectra from VUV single-photon probing. The time resolution extracted from cross-correlation measurements is $65\pm10$ fs for both probing schemes and the pulse duration of H9 is found to be $35\pm8$ fs

Academic Misconduct: Methods of Influencing Undergraduates\u27 Perceptions of the Seriousness and Frequency of Cheating.

Academic misconduct is a problem that all institutions of higher education experience. Because few incidents are worthy of national attention, the media create the impression that cheating is rare. The truth is that, depending on the source, up to 75% of college students admit having cheated on exams, papers, and other academic activities. One approach to promoting ethical behavior on campus is a framework based on student development theories. William Kibler of Texas A&M University has created a comprehensive program which includes intervention strategies designed to promote an ethos that nurtures academic integrity. Two components in this plan are a written honor code and the communication of behavioral expectations. This study focused on those two components and their potential to influence undergraduates\u27 perceptions of the seriousness and frequency of cheating at Louisiana State University (LSU). The experiment consisted of a single-factor multiple treatment design with four treatments. The treatments, or independent variables, are (1) presentation by the classroom instructor, (2) distribution of the written code of student conduct, (3) showing a video using student actors, and (4) no-treatment control. The dependent variables were the perception of the seriousness of cheating and of the frequency of cheating at LSU. A self-report survey was administered to four sample groups. The data collected from 674 subjects were analyzed by an ANOVA, the Tukey\u27s (HSD) Test, a simple frequency count/percent, and an ANOVA item analysis. On the analysis of items relating to seriousness of cheating, two patterns emerged. One illustrates the influence of the instructor and the other, the lack of influence of having students read the code of conduct. The item analysis relating to frequency of cheating revealed a significant statistical difference between the instructor\u27s group and the group which saw the video. These data indicate that the communication of expectations by the instructor is the most effective means of influencing student perceptions. That is good news for institutions unable, due to personnel or fiscal constraints, to create the comprehensive program Kibler outlines. It is both effective and inexpensive to utilize the power of faculty to promote an atmosphere of academic integrity
