The purpose of this study was to test the hypothesis that self-reported physical activity (PA) levels quantified from the International Physical Activity Questionnaire (IPAQ) could be used to improve the prediction of percent body fat (%BF) measured by dual-energy X-ray absorptiometry (DXA) from body mass index (BMI), gender, and race in White and Black college students. A total of 278 students, aged 18 24 yr, volunteered to participate. There were 133 males (85 White and 48 Black) and 145 females (77 White and 68 Black). Total activity levels were quantified in MET-hours per week (MET-hrswk-1) using the IPAQ short form. Height and weight were measured and BMI values calculated (kgm-2). Percent fat was assessed using DXA. Regression analysis was used to determine the impact of MET-hrswk-1 on the relationship between %BF and BMI, taking gender and race into account. The prediction sum of squares (PRESS) statistic was used to cross-validate the models. Mean (± SD) values were as follows: MET-hrswk-1 37.4 ± 21.9, %BF 24.5 ± 9.3%, and BMI 24.4 ± 4.1 kgm-2. Percent body fat was significantly correlated with MET-hrswk-1 (r = -0.44, p < 0.0001) and BMI (r = 0.38, p < 0.0001). Stepwise regression analysis of a reduced model with BMI, gender and race produced an R2 value of 0.81 (root mean square error [RMSE] = 4.07). The full model with MET-hrswk-1 marginally improved the prediction of %BF (R2 = 0.83, RMSE = 3.87). When cross-validated, the corresponding PRESS statistic for the reduced and full model was 4.10 and 3.90, respectively. These results suggest that %BF can be predicted with greater precision and accuracy in a college-aged population when MET-hrswk-1 are included in addition to BMI, gender, and race.

The importance of images as a means of persuasion in advertisements, with few exceptions, has been viewed as secondary to copy (text) in advertisements. Even though images play an important part in the communication of messages for fashion apparel, research to develop an understanding of how images influence consumers is needed. Hypotheses were developed to test the proposition that viewersâ level of advertisement and fashion involvement would be moderated by type of advertisement treatment for a fashion product considered controversial: (1) copy and image, (2) copy only, and (3) image only. <br> Involvement, as a state that can be measured along a continuum, served as the theoretical framework. The Revised Personal Involvement Inventory (RPII) was used to measure advertisement involvement. The Fashion Involvement Index (FII) was used to measure fashion involvement as a function of product involvement. Both scales had dimensions that provided additional information to test an overall state of involvement. <br> A mail survey was conducted of a sample of 1,200 women with intended household income of $75,000 or higher, living in eight major metropolitan areas of the United States. The response rate was 23%. In general, the respondents were highly educated; over 30 years of age; white, not of Hispanic origin; married; full-time employed professionals; and affluent. Hypotheses were tested using multiple regression (MR) and Pearson correlation analyses. Variation in advertisement treatment produced no moderating effects on involvement with the advertisement. Age was the only demographic characteristic found to moderate the relationship between fashion involvement and involvement with the advertisement as measured on the pleasure dimension of the RPII. There were significant relationships between fashion involvement and ownership of leather products and between level of advertisement involvement and ownership of leather products. Results also showed significant relationships between fashion involvement and media exposure and between advertisement involvement and media exposure. Results in this study contribute to an understanding of the role of images in print advertisements for fashion apparel and further support the external validity of advertisement involvement as measured by the RPII and fashion involvement theory as measured by the FII.

The purpose of the study was to measure the current level of communicative initiations exhibited by children enrolled in the LSU preschool program. Child communication was categorized as specific, unclear, or negative. These descriptors referred to peers ability to interpret the target childs communication. Additionally, peer responses were recorded as either positive or negative based on their reaction to the target childs communication. Children identified with either low levels of communicative initiation or unclear/negative communications were targeted for the intervention. Single-subject research methods were used to record each childs communicative behaviors. A least-to-most assistive prompting (Horner & Keilitz, 1975) intervention was applied as teacher mediation in the form of coaching. All three children demonstrated an increase in their specific communication toward peers when the LtM teacher prompting intervention was applied; additionally, increases in positive peer responses were also observed.

In a teacher-directed activity, such as whole group, children can learn new skills by following the teachers directions and/or model the teachers behaviors. The National Association for the Education of Young Children Developmentally Appropriate Practices provides several recommended practices for creating a community of learners. When teachers follow these strategies they are providing multiple opportunities to engage children (Bredekamp & Copple, 1997). When used appropriately, whole group instruction can be very effective when teaching and can be used at various times of the day. Whole group instruction builds a sense of community among the classroom. The purpose of this study is two fold: 1) to establish normative data to determine typical levels of correspondence with recommended practice and typical levels of child task engagement during whole group instruction 2) to modify the whole group activity to determine if child task engagement is impacted. This identifies the levels of task engagement of children during whole group instruction, while concurrently describing the whole group instruction in terms of recommended practice for preschool. The purpose is to determine if the identified criteria for recommended practice in whole group instruction will impact child task engagement during this activity. The settings for the targeted classrooms were three preschool classrooms. Each of the three classrooms was selected based on their performance as compared to the normative data in Phase One. These three classrooms had the highest amount of children exhibiting low levels of task engagement and low number of recommended practice for whole group instruction. Results indicated that when each of the teachers increased their adherence to the recommended practice in whole group instruction, childrens task engagement was observed to increase.

Resistant starch (RS) is fermentable dietary fiber. It has been shown that inclusion of resistant starch in the diet causes decreased body fat accumulation and altered gut hormone profile. Gut hormone has complex effect on neuropeptides expression in the brain hypothalamic area which is regarded as key factors in regulation of energy homeostasis. In this project, thereby, it is proposed that 1) the hypothalamic neuropeptide Y (NPY), agouti-related peptide (AgRP) and pro-opiomelanocortin (POMC) mRNA expression may be altered by RS feeding; 2) afferent vagal nerves might be involved in this process. Animal experiment was conducted to investigate the hypothesis. The rats were injected intraperitoneally with capsaicin to destroy unmyelinated small vagal afferent nerve fibers. The cholecystokinin food suppression test was performed to validate the effectiveness of the capsaicin treatment. Then, capsaicin treated rats and vehicle treated rats were subdivided into a control diet or a resistant starch diet group, and fed the corresponding diet for 65 days. At the end of study, body fat, food intake, plasma peptide YY (PYY) and glucagon-like peptide -1 (GLP-1), and hypothalamic pro-opiomelanocortin, neuropeptide Y, agouti-related peptide gene expressions were measured. Resistant starch fed rats had decreased body fat, increased POMC expression in the hypothalamic arcuate nucleus, and elevated plasma PYY and GLP-1 in both the capsaicin and vehicle treated rats. Hypothalamic NPY, AgRP gene expressions and food intake were not changed by resistant starch or capsaicin. Therefore, destruction of the capsaicin sensitive afferent nerves did not alter the response to resistant starch in rats. The conclusion is that dietary resistant starch might reduce body fat through increasing the hypothalamic POMC expression and vagal afferent nerves are not involved in this process.

Obesity is one of the most pressing public health concerns in Louisiana. There are numerous reasons believed to be major contributors to the obesity epidemic, one of which is dietary habits. The purpose of this study was to investigate and identify the dietary patterns of southern Louisiana residents. A self administered, semi-quantitative questionnaire was used. Subjects (n=308) were recruited from Louisiana State University (LSU). Results suggested that it is possible to describe the dietary patterns of a southern Louisiana population. Compared to whites, the percentage of African Americans who were served or consumed fried fish, rice, red beans and rice, and fried chicken was significantly higher. Men were more likely to have consumed or been served fried chicken, hamburgers, steak, and meatloaf compared to women. The most frequently consumed or served foods included breakfast cereal, luncheon meat sandwiches, spaghetti, vegetables, baked chicken and wild game meat. Results from this study could be used to develop diets, nutrition education material, and interventions that are tailored specifically to this region.

The study examined the possibility of relationships between caregiver sensitivity across multiple caregivers during the childs first three years of life and both childrens later perceived peer acceptance and childrens later perceived maternal acceptance. Data were collected from 26 children, aged between 5 and 8-years old, and the 32 unique caregivers that the children had experienced during their first 36 months in child care. Assessments were made using the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPC, Harter & Pike, 1984) and the Caregiver Interaction Scale (CIS, Arnett, 1989). Correlations were calculated among the 7 primary variables for the children: number of unique caregivers, number of snapshots (i.e., points of time at which caregiver data was collected), age in months at testing, peer acceptance, maternal acceptance, average level of caregiver sensitivity, and rate of change of caregiver sensitivity. Significant positive correlations were found between perceived peer acceptance and perceived maternal acceptance. No statistically significant relationships were found among the remaining variables; that is, the measures of cumulative caregiver sensitivity did not predict the childrens later perceptions of peer acceptance or of maternal acceptance. Possible explanations for the absence of statistically significant relationships are discussed.

The purpose of the study was to examine the relationship between childrens experiences of caregiver sensitivity during the first three years of their life and their later self-perceptions of cognitive competence and cognitive performance. Caregiver sensitivity was measured using data that had been collected with the Caregiver Interaction Scale (CIS, Arnett, 1989) during an earlier longitudinal study, the Baton Rouge Early Care Study (BRECES; Pierce & Benedict, 2007). Measures of cognitive competence were derived using the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (Harter & Pike, 1984) and measures of cognitive performance were derived using the Peabody Picture Vocabulary Test (Dunn & Dunn, 1997). Data were collected from 26 children for whom the researchers had measures of caregiver sensitivity for a minimum of 18 months. Bivariate correlations and t-tests were used to examine the relationship between childrens cumulative level of sensitivity experienced during the first 36 months of child care and the predicted outcomes. No statistically significant relationships were found.

The purpose of these studies was to determine whether weight status, nutrient intake, and dietary adequacy were associated with breakfast consumption patterns. A representative sample of African American (AA) children and adolescents who participated in 1999-2002 National Health and Nutrition Examination Survey (NHANES) was used in a secondary data analysis. Participants were first grouped by age: 1-12 years of age (y) (n=1,389), 13-18 y (n = 988) and then by breakfast consumption category: breakfast skippers, ready-to-eat cereal (RTEC) consumers, and other breakfast consumers. A single multiple-pass 24-hour dietary recall was conducted using computer-assisted software to record dietary intake. To estimate dietary adequacy, the mean adequacy ratio (MAR) was calculated by expressing micronutrient intake as a percentage of the Estimated Average Requirement , truncated to no more than 100%, and averaged over 13 micronutrients: vitamins A, E, C, B1, B2, B6, B12; niacin; folate; phosphorus; magnesium; iron; and zinc. Sample-weighted data were used in all statistical analyses. In children, 7.4% of AA 1-5 y and 16.9% of AA 6-12 y, respectively, skipped breakfast while RTEC consumers included 45% and 38%, respectively. In AA 13-18 y, 36.8% skipped breakfast and 19.4% consumed RTEC at breakfast. Ready-to-eat cereal consumers 1-12 y had the lowest mean body mass index (BMI) (p≤0.05) and mean waist circumference (WC) (p≤0.05). They also had the highest mean intakes of vitamins A, B-6, and B-12; thiamin; riboflavin; niacin; folate; calcium; iron; and zinc; highest MAR (p≤0.05); and the highest intake of carbohydrates and total sugars, and the lowest intakes of total fat (p≤0.05). RTEC consumers 13-18 y had lower mean WC (p≤0.05) and BMI (p≤0.05) than breakfast skippers. Adolescent RTEC consumers and other breakfast consumers had higher mean energy intakes than breakfast skippers (p≤0.05) and had the highest MAR, while breakfast skippers had the lowest MAR (p<0.05). Adolescent RTEC breakfast consumers had higher intakes of vitamins A, B-6, B-12; thiamin; riboflavin, niacin; folate; and minerals calcium, phosphorus, magnesium, iron, zinc, and potassium than breakfast skippers and other breakfast consumers (p<0.05). Consuming an RTEC breakfast was associated with improved weight, nutrient intake, and dietary adequacy in AA children and adolescents.

The results of a content and historical analysis of American postmortem photographs from 1840 to 1900 found in Sleeping Beauty: Memorial Photography in America and Sleeping Beauty II: Grief, Bereavement and The Family In Memorial Photography American & European Traditions by Stanley Burns (1990 and 2002) indicate that day dress was the most popular form of postmortem dress depicted in the photographs. A comparison of the findings from this examination of the dress of 89 deceased individuals depicted in 84 postmortem photographs with descriptions of dress based on nineteenth century archaeological burial remains and portraits of living individuals indicates that deceased individuals were most often photographed and buried in their Sundays finest or nicest items of day dress. Deceased individuals were most likely photographed in their burial dress and the appearance gave the impression of a respectable final portrait. Postmortem dress was described and categorized by decades from 1840 to 1900 and by age and gender including adult male, adult female, child male, child female and infants. Postmortem dress was compared to period photographs, illustrations, and descriptions of extant burial dress. Relationships were examined between postmortem dress and nineteenth century cultural belief systems. Differences in postmortem dress are closely associated with differences in the dates of the photographs and the age and gender of deceased individuals. Day dress, the most popular category of postmortem dress, followed fashion cycles over time and differences in postmortem dress were associated with differences in fashionable dress styles during the period. Postmortem dress depicted in postmortem photographs was influenced by many societal and individual level factors. Many of the customs and beliefs held by individuals, families, and friends in the nineteenth century influenced choices of postmortem dress. Postmortem dress is a reflection of nineteenth century American culture and the study of postmortem dress leads to a better understanding of customs and beliefs associated with this period.
