The psychological nature of conscience in Freudian theory

Thesis (Ph.D.)--Boston UniversityThis dissertation attempts to investigate the psychological nature of the conscience in Freudian theory and evaluate it in the light of certain neo-Freudian and non-Freudian findings. Special attention is given to the original work of Sigmund Freud and particular emphasis is placed on his concept of the super-ego, In psychological literature conscience is generally referred to as the super-ego. For Freud, the super-ego comes into being through the psychic processes of repression, identification and introjection. Its central task is that of playing the role within the personality once occupied by the parental or other authorities. The super-ego tends to accent the harshness, severity and restrictiveness of the parents far more than their love and kindness. Other Freudians, notably Bergler, Flugel, Klein and Jones expand Freud's early theories of conscience as a stern and punitive tendency in personality. They see the ideal self-image as of little value and rooted in unrealistic expectations [TRUNCATED

Assessment of Excess Thyroid Cancer Risk Following a Hypothetical Radiological Incident in Louisiana and Best-Case Risk Reduction Achieved by Thyroid Blockade

Radioactive isotopes of iodine are produced by nuclear power plants as a byproduct of nuclear fission reactions. If these isotopes are released into the environment, such as during a breach of containment, they constitute a health risk to exposed individuals. To mitigate the risk of thyroid cancer due to exposure to radioactive iodine, “iodide prophylaxis,” also known as “thyroid blockade,” can be used, usually by administration of potassium iodide (KI). In some areas of the world, KI has been provided to the general public by their governments as a precautionary measure against potential nuclear power plant incidents. However, in the state of Louisiana, only evacuation and sheltering of the general public are the planned response to such incidents. The question of whether Louisiana’s government should provide KI to the public is a question of risk management. This project’s risk assessment provides a framework for determining radiation risk from radioiodine release from a nuclear power plant, enabling an assessment of the potential benefit of providing KI to the general public in Louisiana. In this assessment, a hypothetical radiological incident of similar severity to the Fukushima accident was modeled for a nuclear power plant in Louisiana. Environmental transport of discharged radioactive iodine was modeled with a Gaussian plume model. Thyroid dose was calculated using representative parameters from International Commission on Radiological Protection Publication 71. Age- and sex-specific values of excess relative risk, lifetime attributable risk, and excess lifetime thyroid cancers were calculated. Lastly, the number of excess lifetime thyroid cancers mitigated by thyroid blockade was estimated through two separate approaches. This assessment found that a plume traveling over highly populated parishes near the power plant could result in approximately 200 excess lifetime thyroid cancers over all age groups. The largest number would likely occur in females exposed as children. Thyroid blockade could potentially mitigate 80 or more of the excess cancers. These results suggest that more comprehensive assessments of KI distribution in Louisiana may be warranted

Quantified Uncertainty in Thermodynamic Modeling for Materials Design

Phase fractions, compositions and energies of the stable phases as a function of macroscopic composition, temperature, and pressure (X-T-P) are the principle correlations needed for the design of new materials and improvement of existing materials. They are the outcomes of thermodynamic modeling based on the CALculation of PHAse Diagrams (CALPHAD) approach. The accuracy of CALPHAD predictions vary widely in X-T-P space due to experimental error, model inadequacy and unequal data coverage. In response, researchers have developed frameworks to quantify the uncertainty of thermodynamic property model parameters and propagate it to phase diagram predictions. In previous studies, uncertainty was represented as intervals on phase boundaries (with respect to composition) or invariant reactions (with respect to temperature) and was unable to represent the uncertainty in eutectoid reactions or in the stability of phase regions. In this work, we propose a suite of tools that leverages samples from the multivariate model parameter distribution to represent uncertainty in forms that surpass previous limitations and are well suited to materials design. These representations include the distribution of phase diagrams and their features, as well as the dependence of phase stability and the distributions of phase fraction, composition activity and Gibbs energy on X-T-P location - irrespective of the total number of components. Most critically, the new methodology allows the material designer to interrogate a certain composition and temperature domain and get in return the probability of different phases to be stable, which can positively impact materials design
