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
AFRICAN AMERICAN WOMEN'S PERCEPTIONS, EXPERIENCES, AND MEANING ASSOCIATED WITH BREAST CANCER SCREENING IN RURAL EASTERN NORTH CAROLINA
No full textThis qualitative study addressed the research question, what are the perspectives and experiences related to breast cancer and breast cancer screening of African American women residing in rural eastern North Carolina? A literature review indicated little research related to the perceptions and experiences of rural African American women about breast cancer and breast cancer screening. In a previously conducted unpublished larger study (Burke, Barrett, & Cherry, 2009), the perspectives of women from rural North Carolina about breast cancer and breast cancer screening were collected by means of focus group interviews. The researcher in the present study conducted a qualitative analysis of data from a sub-set of focus group interviews that involved African American women. A qualitative approach in this study afforded an opportunity to gain insight into African American women's experiences and views regarding breast cancer and breast cancer screening. The researcher analyzed transcripts from three focus group interviews that involved 17 African American women residing in rural eastern North Carolina. Five themes that emerged from the data were: knowledge and beliefs about breast cancer, influences on breast cancer screening behaviors, personal experience with screening, emotional reactions to discussing breast cancer and breast cancer screening, and promoting breast cancer screening. Key findings related to these emergent themes included a self-perceived low level of knowledge about breast cancer, cultural views about various causes of breast cancer, perspectives about mammograms, perceived barriers to breast cancer screening, the influence of faith on breast cancer and breast cancer screening, personal experiences with breast cancer screening, fear as a commonly shared reaction to breast cancer and breast cancer screening, and best practices for promoting breast cancer awareness and education. The researcher identified a need for future research on the topic of minority health in rural populations, specifically around breast cancer screenings and preventive health. An analysis of a sub-set of qualitative data provided by African American women and a comparison of findings with the research literature led the researcher to recommend that tailored health education be provided African American women on the topic of breast cancer and breast cancer screening.M.A
Integrative Health Coaching : A Phenomenology of Clients' Discoveries
No full textThe field of health coaching has experienced significant growth in response to the social and economic burden of chronic disease. Integrative health coaching (IHC) applies the principles of integrative medicine and a motivational coaching process to engage clients with attaining self-determined goals. The literature at the time of this study had not examined clients' experiences and meanings in the developing health promotion practice. The purpose of this study was to describe the lived experience of IHC for adult clients who sought the coaching intervention to address a chronic health condition. The researcher applied a phenomenological approach in the study. Nine participants voluntarily responded to a UMCIRB approved study announcement distributed to clients by integrative health coaches at Duke Integrative Medicine. The collection of qualitative data occurred through in-depth and photo-elicitation interviews. Analysis entailed Moustakas' process of phenomenological reduction and coding using qualitative software. Study participants acknowledged the difficulty of lifestyle change and readiness to improve their health. Their participation in IHC involved building intrinsic motivation to attain self-defined goals with the support of the coach-client relationship. The essence of clients' IHC experience was engagement in transformational change. Study participants' descriptions revealed four key structures: a) the integrative medicine framework; b) the health coaching process; c) the sense of transformational change; and, d) engagement. The study findings described client engagement in a health coaching process that uniquely applied mindfulness and integrative medicine practices. This study contributes to an understanding of the dynamics of mindfulness and integrative medicine in the emerging health coaching practice. The nine IHC clients' experiences provide insights for health professionals who seek to engage persons living with chronic health conditions in a process that supports their self-determined efforts toward goal attainment and realizing health and well-being.

Perceptions About Vaccination by Obstetricians and Gynecologists : A Phenomenological Approach
No full textBackground - The field of immunizations has grown in recent years with the introduction of new vaccines for adolescents and adults. Despite these advances, adolescents and adults are often under-immunized and may be susceptible to the effects of harmful diseases. A need exists to expand venues in which adolescents and adults can receive vaccines, and to educate health care providers about the existence and importance of administering immunizations to these age groups. In particular, obstetrician-gynecologists (OB/GYNs) are in a unique position to make a significant impact on immunization education and vaccination rates for women of all ages. Yet, researchers know little about their vaccination practices and opinions about immunizations.M.A
THE MEANING AND LIVED EXPERIENCE OF DEPLOYMENT AS PERCEIVED BY MILITARY OFFICERS' SPOUSES/PARTNERS
No full textThis study addressed the question, "What is the lived experience of and meaning held by military officers' spouses/partners regarding multiple, year-long or longer deployments of their active duty military wife/partner in the post-9/11 era?" A literature review indicated a paucity of information about this relatively new phenomenon and that the impact on spouses/partners warranted investigation. Study findings provide insight for health professionals about the stressors experienced and coping mechanisms utilized by military officer spouses/partners during repeated yearlong or longer deployment. The findings afford an in-depth understanding of the complex and emerging issues faced by these individuals. The researcher used Max van Manen's approach to hermeneutic phenomenology to guide the study. This approach focused on employing individuals' reflections on their experiences to reach an understanding of the deeper meaning of the experience. The essence of the experience was ambiguous loss and resilience. The researcher used purposive sampling to recruit seven participants who were spouses of military officer spouses for five and seventeen years and who experienced between two and six spousal/partner deployments. Strategies to address study credibility included methodological congruence, triangulation, thick description, prolonged engagement in the field, continuing search for disconfirming evidence, verbatim transcription, engagement in reflexivity, maintenance of an audit trail, and data saturation. Data were coded and analyzed for patterns and themes in an effort to identify the essence of participants' lived experience. M.A
