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
Impact of the Changes in Health Care on Nursing Roles Over the Past Five Decades: An Integrative Review
No full textBackground: Dean Emeritus Lucy Harris wrote a book in 1973 outlining the history and struggles of Texas Christian University's Harris College of Nursing, while also posing challenges for nursing in the future. Five decades after the publishing of Dean Harris' work, a Harris College graduate, former faculty, and now adjunct faculty member completed a new book to address Dr. Harris' challenges and discuss changes in Harris College from 1973 to 2018. Purpose: The purpose of this integrative review is to identify changes in health care and discuss how they have impacted nursing roles over the past five decades. Methods: Numerous health care-related databases and nursing journals were searched to find information on changes in health care and nursing roles over the past five decades. Forty-seven pertinent articles were selected based on inclusion and exclusion criteria and appraised using the Johns Hopkins Evidence Based Practice Research and Non-Research Appraisal Form. Findings: Health care policy, technology, structure, and payment systems have changed vastly over the past five decades to create a more equitable, safe, and higher-quality health care environment. Nurses have responded to these changes by becoming better advocates for their own safety, increasing their autonomy in patient care, and championing initiatives and polices to improve patient safety. Conclusion: A multitude of changes in health care structure and function have occurred over the past five decades, which triggered changes in nursing roles. Consequently, progression of nursing roles indicates the responsiveness of the nursing profession to health care changes. Implications for Nursing: Although nurses have responded to health care changes well overall, progress is still needed in improving nursing education on patient care technology and reducing the nursing shortage. Further research is needed into topics discussed in this article as well
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
Reliability of the Short Tool in Measuring Infant Feeding Factors Among Mothers of Infants in the Neonatal Intensive Care Unit
No full textExtensive research has determined breastfeeding provides widespread benefits, including protection against disease for a newborn, decreased postpartum complications for a mother, and a cost-effective safe lifestyle choice for the environment. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for six months as the normative standard for infant feeding (Eidelman et al., 2012). Likewise, The World Health Organization (WHO) has reaffirmed the AAP's Breastfeeding Policy and states "breastfeeding is the normal way of providing young infants with the nutrients they need for healthy growth and development" (WHO, 2011). In the Neonatal Intensive Care Unit (NICU), the choice to breastfeed is affected by many factors including parental stress, access to lactation consultant education, and the health of the critically ill newborn. Researchers have exhausted literature and concluded no tool exists to measure the factors that influence a woman's decision to breastfeed an infant in the NICU. Therefore, the investigators created a 32 item questionnaire to measure factors affecting breastfeeding. The original long-form tool was created and a preliminary round of data was collected. The Texas Health Fort Worth (THFW) team used regression and factor analysis to create a short-form measure with 15 items. This new short-form tool was distributed amongst the same population of mothers with infants in the THFW NICU. Finally, the tool's psychometric properties will be analyzed and with success, this tool can be administered to mothers across the nation to determine barriers to infant feeding in the NICU
Development of a Tool to Measure Factors Affecting Breastfeeding in the Neonatal Intensive Care Unit
No full textExtensive research has been done investigating the benefits breastfeeding provides for both the baby and the mother and there is enough evidence to encourage mothers to breastfeed if possible for at least six months. Much less is known about the mother's experience with breastfeeding in general and in specific situations, like in the NICU. The studies previously completed on barriers to breastfeeding in the NICU have identified several barriers that mothers trying to breastfeed may face (Boucher, Brazal, Graham-Certosini, Carnaghan-Sherrard, & Feeley, 2011; Callen, Pinelli, Atkinson, & Saigal, 2005; Myers & Rubarth, 2013). There have also been several tools developed measuring the experience, self-confidence, and motivation of mothers trying to breastfeed (Cleveland & McCrone, 2005; Leff, Jefferis, & Gagne, 1994; Wheeler & Dennis, 2012). There has yet to be a tool developed to measure specific barriers faced by breastfeeding mothers in the NICU, which is what this study aims to accomplish. This literature review is the first step in developing a tool that can measure the barriers to breastfeeding in mothers with an infant in the NICU. The tool was developed using a pilot study that included cognitive interviewing and will be followed by a larger study including 380 participants. The tool's psychometric properties will be analyzed and the predictive validity of the measure will be evaluated by the feeding method used at discharge. With success, this tool can be used widely to help eliminate barriers for mothers globally
Successful Transitions or Opportunities for Improved Care
No full textTransitioning young adult (YA) survivors of pediatric cancer to the adult care setting is a multifactorial challenge. A successful transition considers the educational, social, developmental, and emotional needs of the survivor. With the number of childhood cancer survivors on the rise, health care providers need to standardize the transition process. The current literature has identified several barriers to transition, but the components of a successful transition still demand attention. The purpose of this study was to gain further insight from YA survivors about their transition experience. Participants were eligible for recruitment if they were eighteen years of age or older and were no longer receiving pediatric oncology services. The total sample included 50 participants. Participants completed a demographic data form and a medical care survey. The medical care survey included "yes/no" questions concerning the consistency and quality of the participants' follow-up care and an open-ended response question regarding the success of the participant's transition from pediatric to adult focused care. Within the sample of participants, 54% of participants responded that their transition out of their pediatric facility was successful, and 40% of participants responded that their transition was unsuccessful. Further analysis of quantitative and qualitative data identified that pediatric oncology providers successfully educate YA survivors about the risk factors related to their cancer diagnosis and treatment. Though survivors are aware of risk factors, there remains a lack of knowledge about the importance of risk-based, long-term follow-up care. The investigators of the current study concluded that YA survivors perceive transition as a complex life requiring a comprehensive approach
Evidence-Based Guidelines Development for the Successful Transition of Young Adult Childhood Cancer Survivors to Adult Care Providers
No full textCurrently, there is a lack of support for pediatric cancer survivors as they transition to adult care. The student researcher outlined this discovery through an extensive review and synthesis of the literature. The major areas of concern for both survivors and care providers (pediatric and adult) are lack of communication between providers and survivors, support for survivors, and education of the survivors. The student researcher used the findings from the review of pertinent literature to create the transition guidelines of survivors based on the American Academy of Pediatric Got Transition Model (AAP, 2014). To facilitate implementation of these guidelines, the student researcher created a workbook for the Life After Cancer Program at Cook Children's Health Care System in Fort Worth. Such guidelines are important because they will help to facilitate a successful transition rate of pediatric oncology survivors to adult care providers
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
