Thesis (Ph.D.)--Boston University. / The effects of aggressive film content upon the aggressiveness of young children and upon their identification choices of persons who might serve as models conduct is becoming a major question with the behavioral sciences and the public charge. There has occurred a renewed interest in the effect of film content with increase of television in the viewing habits of children. Most of the available media from which to draw observations concerning mass media were published twenty or so years ago. These data were acquired when motion picture films were still a novelty in the behavior of children and when television was non-existent. The effect of the film upon the behavior of present day children should differ as the viewing counts and general amount of exposure to films has changed. [Truncated]

Thesis (Ph.D.)--Boston University. / Reason as the instrument of philosophy is under attack at the present from the standpoint of psychology, critical philosophy, the experience of evil, science, and existentialism. Rationalism as deduction no longer is an adequate concept of reason. This dissertation investigates the nonrationalistic content of reason required to supplement deductive rationalism in order to develop a coherent and synoptic view of reason as the instrument of philosophy in current times. Mind is defined as the sum total of consciousness, with emphasis upon the unity of the self. [TRUNCATED]

Thesis (Ph.D.)--Boston University. / The purpose of the studies presented in this paper was to attempt to elucidate the nature of the substance contained in staphylococcal culture filtrates which are responsible for their ability to hemolyze mammalian erythrocytes, particularly those of the sheep and the rabbit. The work was centered upon the selection of strains capable of producing filtrates of potent hemolytic activity; a study of several methods or hemotoxin production to improve this ability, and of filtration to ensure minimal loss of hemotoxic fractions; the standardization of a spectrophotometric method for accurate determinations or 50% hemolytic end-points; the definition or conditions required for separation of the hemolytic principles from culture filtrates and for their optimum yield and purity; and some of the properties or the hemalysins. A review of the literature concerning the various phases of the problem is given. Many methods have been described for the production of staphylococcal toxins, the more recent of these involving the use or chemically defined liquid media. It has been generally agreed that strains of Staphylococcus aureus also require the presence of CO2 in the atmosphere for adequate production of the hemolysins. Opinions have differed, however, as to the amount of CO2 required, and also concerning the length of the culture period required for peak toxin production. [TRUNCATED]
