The Effect of Learning-Set Acquisition on the IQs of Disadvantaged Preschool Children

Description: General learning ability is a combination of many relatively independent abilities, some of which have not yet been identified and studied experimentally. The acquisition of learning sets, a learning ability which has received considerable attention in the literature, involves the ability to solve single problems, generalize their solutions, transfer such information from one problem to another, and form concepts. Learning set is the acquired ability to solve a particular kind of problem. Discr… more

Effect of Light and Other Environmental Factors on Growth and Carotenogenesis of Corynebacterium Species Strain 7E1C

Description: This investigation studies effects of environmental factors on growth and carotenogenesis in Corynebacterium strain 7ElC. Changes in pH were found to effect growth more than carotenogenesis. However, certain nutrients or long incubation periods stimulated carotenoid formation more than growth. Dark conditions in a mineral salts-glucose medium stimulated growth, but minimized carotenogenesis. Tryptic soy broth or yeast extract elicited carotenogenesis in darkness. Although brief light exposure d… more

The Effect of Light on Carotenoid Synthesis in Corynebacterium 7E1C

Description: The effects of light, light "mimicking" chemicals, and protein synthesis inhibitors on the photo-induced carotenogenesis of Corynebacterium 7EIC were studied. Changes in the dosage of fluorescent light applied to dark grown cells showed a dose related carotenogenic response. Maintaining the same dosage but varying the wavelength of monochromatic light revealed that light with a wavelength of 280 to 450nm was responsible for photo-induction. It further showed a peak of photo-induction between th… more

Effect of Loneliness on Older Adults' Death Anxiety

Description: Previous research, as well as theory, has supported the existence of a relationship between death anxiety and loneliness in older adults but a causal examination has not been possible until now. A hypothesized model was developed which states that loneliness will lead to death anxiety mediated by cultural worldview. Longitudinal data was analyzed using Structural Equation Modeling in order to more fully explore this potentially causal relationship. The primary model was supported suggesting tha… more

The Effect of Long-Term Moderate Amounts of Ethanol on Paraventricular Nuclei Activity on Cold Stressed Adult Rats

Description: The effects of moderate, long-term intake of ethanol on the hypothalamic response to cold stress were examined. The long-term experimental animals were given .25 ml of 28% ethanol or .25 ml of water orally once a day, five days a week for fourteen months. A stainless steel electrode was then surgically implanted into the paraventricular nucleus, after which the animal was subjected to cold stress (-150 C, 10 min.). Recordings were taken in the forms of frequency and activity. The data clearly i… more

The Effect of Maternal Employment on the Sex Role Orientation of Adolescents

Description: The sex-role orientation was determined for 352 high school seniors in Plano, Texas. Using maternal employment status as the independent variable, the students were divided according to full-time employed mothers or full-time homemaker mothers. Results indicated that adolescents of employed mothers had a more liberal sex-role orientation and attitude towards the division of household tasks than adolescents of homemaker mothers. When male and female scores were analyzed separately, the order fro… more

The Effect of Media Constituents on Growth and Pigment Production of Mycobacterium Phlei, Pseudomonas Fluorescens, Pseudomonas Aeruginosa, and Staphylococcus Citreus

Description: Little is known concerning the production and significance of bacterial pigments. There is seemingly an open field for studying the effects produced by varying the nutritive content of culture media upon which organisms are grown. This has led to an especial interest in, and the purpose of this investigation.

The Effect of Membership in the Council of Adult and Experiential Learning on the Quality of Prior Learning Assessment Services in Senior Level Institutions Accredited by the Southern Association of Schools and Colleges

Description: Over the past 20 years there has been a dramatic increase in the number of adults enrolling in institutions of higher education across America. Adult students presently constitute nearly one-half of all undergraduate enrollment. This influx of adults has generated interest in nontraditional programs, including external degree programs, degree completion programs, and prior learning assessment programs. The purpose of this study was to determine if an association existed between membership in th… more

The Effect of Memory Requirement on Schema Learning

Description: A number of previous investigations have suggested that schema learning would be more readily facilitated by a recognition task than a reproduction task due to the increased memory requirement of the reproduction task. Differential memory requirements of 0, 4, 8, 16 and 32 seconds were imposed on 50 Ss in a recognition task to determine if increased memory requirements improved schema learning in the same mode as the reproduction task. The results indicated no significant improvement in schema … more

The Effect of Menthol on Nicotine Metabolism: a Cross Species Evaluation

Description: The effect of menthol on nicotine metabolism was examined in liver S9 fractions of four different species and in the in vivo mouse model. The purpose of this study was to investigate three parameters: (1) biotransformation of nicotine to cotinine in various species (human, mouse, rat and trout) using in vitro methods; (2) to determine if the addition of menthol with nicotine altered biotransformation of nicotine to cotinine; (3) and to assess similar parameters in an in vivo mouse model.

The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain

Description: The purpose of this study was to evaluate the effect of mode and intensity on VO2 kinetics in the severe intensity domain. Seventeen participants completed 3-7 tests each on a cycle ergometer and treadmill. For each test, Tfatigue, VO2max, Tmean response, VO2GAIN, TVO2max and T@VO2max were determined. Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue . VO2max values were higher in running. The VO2 response profile was faster for running than cycl… more
