The Effects of Long Term Modernate Ethanol Intake on Plasma Levels of ACTH, Beta Endorphin, and Corticosterone in Rats

Description: The effects of single injections and daily oral administration of ethanol on plasma levels of ACTH, beta endorphin, and corticosterone in response to cold stress were examined. The long-term experimental animals were given 0.25 ml of 28% ethanol or water orally once a day, five days a week, for fourteen months. Plasma levels of ACTH, beta endorphin, and corticosterone were lower in alcohol-treated rats as compared with water-treated rats when exposed to cold stress. The effects of a single inje… more

The Effects of Low-Intensity Exercise on Neurocognitive Function

Description: Acute aerobic exercise exerts a small beneficial effect on cognition. Much of the research to date has focused on cognitive changes following a bout of exercise, while little is currently known about changes in cognitive performance during exercise. The limited research that has been conducted suggests either positive, negative, or no effects on cognitive performance during exercise. Thus, the primary purpose of this study was to examine the effects of low-intensity cycling on cognitive functio… more

The Effects of Lower Body Negative Pressure on the Cardiovascular System: The Relationships of Gender and Aerobic Fitness

Description: Sixteen males and sixteen females were recruited for this study; eight of each gender were aerobically trained athletes; the remaining eight were untrained control subjects. Each subject performed a maximal exercise stress test for aerobic capacity (VO2max). On a separate day the blood volume and the cardiovascular responses to progressive (0 to -50 torr) lower body negative pressure (LBNP) were determined. The female subjects were observed to be significantly more tolerant of the LBNP than th… more

Effects of Lysolecithin on Macrophages

Description: The effect of lysolecithin on the macrophage was studied using five macrophage function assays. The results of indicate that lyso lecithin is a macrophage activating agent which causes enhanced cell spreading, increased phagocytosis of sheep erythrocytes, heightened membrane activity in the presence of damaged autologous red blood cells, chemotaxis, and vigorous phagocytosis and intracellular killing of Staphylococcus albus.

Effects of Macrophyte Functional Diversity on Taxonomic and Functional Diversity and Stability of Tropical Floodplain Fish Assemblages

Description: Multiple dimensions of biodiversity within and across producer and consumer guilds in the food web affect an ecosystem’s functionality and stability. Tropical and subtropical aquatic ecosystems, which are extremely diverse, have received much less attention than terrestrial ecosystems in regards to the effects of biodiversity on ecosystem functioning. We conducted a field experiment that tested for effects of macrophyte functional diversity on diversity and stability of associated fish assembl… more

The Effects of Mainstreaming on the Self-Concept of Physically Handicapped Children

Description: The Piers-Harris Self-Concept Scale for Children, the Florida Key: A Scale to Inter Learner Self-Concept, and the Walker Problem Behavior Identification Checklist were used to assess the self-concepts of 18 ambulatory physically handicapped children between the ages of 6 and 12 years. Data were analysed via one-sample t-tests. The hypothesis that mainstreamed handicapped children would exhibit somewhat lower self-concept than their nonhandicapped peers was not supported. In fact, some mainstrea… more

Effects of Male and Female Speech Styles on the Perceptions of Clinical Psychologists

Description: Previous research suggests that gender-appropriate and gender-inappropriate use of sex-linked linguistic markers alters subjects' perceptions of the speaker. The present study examined the effects of male and female speech styles on clients' perceptions,. Undergraduates (N = 160) listened to audiotapes of clinical psychologists introducing the same client to psychotherapy. Clinician gender and sex-linked linguistic markers were manipulated. The results suggested that sex-stereotypes of males, f… more

Effects of Managerial Risk Propensity and Risk Perception on Contract Selection: Revisiting the Risk Neutrality Assumption of Transaction Cost Economics (TCE)

Description: Contract selection is at the forefront of risk management and mitigation, yet it is an underrepresented area of research in supply chain management field as well as the influences of individual-level risk propensity and risk perception on supply chain decision-making processes. This dissertation explores effects of managerial risk propensity and risk perception on contract selection through the theoretical lens of Transaction Cost Economics (TCE), using a vignette-based experimental research de… more

Effects of Manifest Anxiety Upon a Measure of Memory Span

Description: This study will attempt to verify the Hullian drive theory, E = f(HxD), as others have done before, but with one exception. The H, or habit strength, will be held to be neutral so that the E, or excitatory potentials, will be a function of drive alone. Without any habit to reinforce, any increase in excitatory potential can be related directly to increase in drive. Four hypotheses were investigated: The first hypothesis was that the HA, or high-anxiety groups, will also be the high-drive groups… more

The Effects of Mastery, Competitive and Cooperative Goals on Performance in Simple and Complex Sport Skills

Description: The present study investigated the effects of different goal and feedback conditions on performance of a basketball field goal shooting task and a more complex one-on-one offensive basketball task. Subjects (N = 100) were matched, based on pre-test performance, into one of five conditions: competitive goal, cooperative goal, mastery goal, "do your best" with feedback, and "do your best" without feedback. Results indicated the competitive group was significantly better than the "do your best" wi… more

Effects of Maternal Aerobic Exercise on Selected Pregnancy Outcomes in Nulliparas

Description: This study evaluated the effects of participation in aerobic exercise on pregnancy outcomes. Pregnancy outcomes included type of delivery, length of labor, gestational age, neonatal birth weight, and maternal weight gain. The 137 nulliparas were categorized as active (N=44) or sedentary (N=93) based on self-reported aerobic exercise. Findings from this study suggest that pregnant women who were active during pregnancy were more likely to have vaginal deliveries than sedentary women. No signific… more

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness

Description: Previous research indicates that women are judged on the amount of food eaten and that both men and women are judged on the type of food eaten. This study is an attempt to determine whether meal size or type predominantly accounts for these findings on the variables of masculinity, femininity, attractiveness, thinness, fitness, and likability. Physical activity was also included to determine its effect on these variable. Subjects used were 313 undergraduate students. Results indicate that meal … more

The Effects of Media Exposure on Body Satisfaction, Beliefs About Attractiveness, Mood and Bulimic Symptomatology Among College Women

Description: The research of Stice et al. (1994) and Stice and Shaw (1994) proposed several mechanisms that may mediate the adverse effects of media exposure to the thin ideal including internalization of the thin-ideal, negative affect, and body dissatisfaction. The purpose of this study was to extend initial research of Stice and Shaw (1994) by incorporating two forms of media (e.g., TV and Magazines) to assess the effects of exposure to the media portrayal of ideal body shape on women's mood, body satisf… more

Effects of Methanol, Atrazine, and Copper on the Ultrastructure of Pseudokirchneriella Subcapitata (Selenastrum Capricornutum).

Description: The toxicity of methanol, atrazine, and copper to Pseudokirchneriella subcapitata (Korshikov) Hindák historically referred to as Selenastrum capricornutum Printz were determined following 96 hrs growth in a modified Goram's growth media. Methanol and atrazine inhibited fluorescence readings in the cultures by 50% (IC50) at concentrations of 2% and 82 µg/l respectively. These toxicity values compared favorably to other published reports. The IC50 for copper was 160 µg/l which is substantially … more
