Identifying Motivation Toward Healthy Behavior in Overweight and Obese Pregnant Women
No full textAbstract: Identifying Motivation Toward Healthy Behavior in Overweight and Obese Pregnant Women Background: Overweight and obese pregnancies are a growing health concern with long-term maternal and child health implications. Current interventions reflect few successful results in meeting or maintaining gestation weight gain guidelines in this population. Motivation represents a factor shown to impact health behavior modification in relationship to diet and exercise, resulting in improved weight management. Aims: The goal of this study is to examine factors influencing motivation reported by overweight and obese pregnant women to embrace healthy behaviors during pregnancy. The specific aims include to: 1) Determine obese and overweight pregnant women's perceived motivation 2) Examine the influence of perceived competence, autonomy support in the health care climate, relatedness, and attitude toward weight gain in pregnancy on motivation 3) Examine motivation in relationship to other factors, i.e. parity, age, marital status, employment status, ethnicity, planned or unplanned pregnancy and BMI 4) Ascertain an in-depth knowledge of obese and overweight pregnant women's perceptions of motivation and healthy behaviors. Methods: This research uses an embedded mixed methods descriptive correlational comparative design. Five Likert scale instruments were used to measure the quantitative data including four instruments developed using the Self-Determination Theory including, the Basic Psychological Needs scale, the Health Care Climate scale, the Perceived Competence scale, and the Self Treatment Regulation scale; the Attitudes Toward Weight Gain in Pregnancy scale represents the fifth scale utilized. Recorded semi-structured interviews ensued over 20-40 minutes to acquire qualitative data using an approximate 20% subset of the overall sample. Data Analysis: Quantitative analysis included descriptive statistics and correlations to look for significant relationships between the independent variables and the dependent variable motivation. Multivariate multiple regression will be used to demonstrate the strongest predictors in complete sample. Qualitative analysis included categorization and coding of the audio text, finding themes among the participants' stories, and extracting direct quotes to support findings. Results: The sample to date includes 65 (goal n=80) women with singleton pregnancies, 14 of which participated in semi-structured interviews. Preliminary findings indicate the mean on a scale of 0-6 for the DV Relative Autonomous Motivation Index related to diet (RAMI) is 3.092 and RAMI: exercise is 3.335. These two dependent variables are significantly correlated with each other and with a number of independent variables including perceived competence, need for autonomy, need for relatedness, and attitude about pregnancy weight gain. The healthcare climate related to exercise is significantly correlated to exercise motivation, however there is not a correlation between the healthcare climate and diet motivation. Content analysis from the interviews revealed four themes, support, listening, need for accurate information, and doing what is best for the baby.Discussion: Overweight pregnant women have indicated they are motivated toward healthy behaviors, perceive themselves as competent, and have positive views of their providers and weight gain during pregnancy, however this does not translate into healthy weight status during pregnancy. Further research needs to identify the disconnection in order to create effective and sustainable interventions to achieve healthy pregnancy weight.This Research Day material is made accessible to the global community via the web
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
