Provision of Maternal Breastmilk in the Neonatal Intensive Care Unit: A Grounded Theory Analysis
Get PDFDespite the importance of providing hospitalized extremely preterm (EP, \u3c 32 weeks gestation) very low birth weight (VLBW, \u3c 1500 grams) infants with mother’s own milk (MOM), a low percentage of neonates are discharged receiving MOM. The purpose of this study was to explore the experience of mothers of EP VLBW infants and related breastmilk provision in the neonatal intensive care unit (NICU) to develop a general theory of maternal breastmilk provision. This grounded theory study implemented classical qualitative methods. Transcribed maternal interviews were analyzed using the web-based data management and analysis platform of Dedoose. A total of 30 mothers, recruited within a large Midwestern hospital’s NICU, were included in this study. Ten participants provided longitudinal data, while 20 provided data at one-time point. Participants were primarily 22-25 years old (30%, n=10), Black (61%, n=20), multiparous (55%, n=18), living with the father of the baby (36%, n=12), and gave birth via Cesarean section (70%, n=23). Interview analyses yielded three core constructs: maternal psychosocial experiences, maternal cognitive experiences, and infant health. We hypothesized that these core constructs impact maternal breastmilk provision through the mediating factor of maternal health. The psychosocial construct encompasses relationships, responsibilities, resources, bonding, and control. The construct of cognition was categorized into knowledge level and initial breastfeeding intentions. Individual theme co-occurrence, chronological distribution of thematic influence, and general conclusions are pending, as they will be derived from code co-occurrence findings and a chronological understanding of the themes. Limitations include the use of a single hospital site for data collection and the hospital’s high level of support for lactating mothers. Future research should explore prominent themes that emerge from this study and their chronological impact on MOM provision. Nurses should implement evidence-based interventions related to these themes to support breastfeeding mothers of EP VLBW infants
Maternal Provision of Mother\u27s Milk and Birth Trauma in the Neonatal Intensive Care Unit: A Grounded Theory Analysis
Get PDFLess than half of very low birth weight (VLBW, \u3c 1500 grams) infants are discharged from the neonatal intensive care unit (NICU) receiving mother’s own milk (MOM), despite its demonstrated importance. Nevertheless, few studies have explored the impact of maternal perceived trauma (MPT) on infant feeding outcomes. The purpose of this study is to describe MPT among mothers of hospitalized VLBW infants and examine infant feeding outcomes with MPT. This analysis is derived from a grounded theory study exploring the maternal provision of milk among a convenience sample of mothers with VLBW infants at a Midwest NICU. This study utilized semi-structured interviews and content analysis to identify common themes (n=30). Data were analyzed using Dedoose, web-based data management and analytical software. A preliminary analysis identified trauma as a prominent theme. Trauma was defined as a mother’s perceived inability to process an experience at the time of the event, a lack of understanding during the time of an event, and the rapid decline of either maternal or infant health. The occurrence of MPT (n=865) was reported most frequently in women described as Black (46%), multipara (57%), married (75%), and ages \u3e 30 (57%). The MPT frequency was greater with cesarean (54%) and hypertensive (71%) births. The MPT frequency with MOM was 63%, but only 23% with exclusive MOM at discharge. This study’s limitations include using a single hospital location and only English-speaking mothers, making the results less generalizable. Additionally, the interviewer’s Latina racial identity may have led to a sense of kinship with some mothers. A better understanding of MPT and those at risk for MPT will allow providers the opportunity to identify interventions to increase MOM feedings at discharge proactively
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
