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
Diet and exercise intervention adherence and health-related outcomes among older long-term breast, prostate, and colorectal cancer survivors
Get PDFGiven the numerous benefits of a healthy diet and exercise for cancer survivors, there has been an increase in the number of lifestyle intervention trials for this population in recent years. However, the extent to which adherence to a diet and exercise intervention predicts health-related outcomes among cancer survivors is currently unknown. To address this question, data from the Reach out to ENhancE Wellness in Older Cancer Survivors (RENEW) diet and exercise intervention trial were analyzed. RENEW was a yearlong telephone and mailed print intervention for 641 older (≥65 years of age), overweight (body mass index: 25.0-39.9), long-term (≥ years post-diagnosis) survivors of colorectal, breast, and prostate cancer. Participants were randomized to the diet and exercise intervention or a delayed-intervention control condition. The RENEW telephone counseling sessions were based on determinants of behavior derived from Social Cognitive Theory (SCT) (e.g., building social support, enhancing self-efficacy). These factors have been hypothesized to improve health behaviors, which in turn should improve health outcomes. Thus, drawing on SCT and prior diet and exercise research with cancer survivors, I hypothesized that telephone counseling session attendance would be indirectly related to health-related outcomes (i.e., physical function, basic and advanced lower extremity function, mental health, and body mass index) through intervention-period strength and endurance exercise and dietary behavior (i.e., fruit and vegetable intake, saturated fat intake). The proposed model showed good fit to the data; however, not all of the hypothesized relationships were supported. Specifically, increased telephone counseling session attendance was related to engagement in all of the health behaviors over the intervention period. In turn, (a) increased endurance exercise was related to improvement in all of the health-related outcomes with the exception of mental health; (b) increased strength exercise was solely related to improved mental health; (c) increased fruit and vegetable intake was only related to improved basic lower extremity function; and (d) saturated fat intake was not related to any of the health-related outcomes. Taken together, these findings suggest that SCT determinants of behavior and the importance of session attendance should continue to be emphasized in diet and exercise interventions. Continued exploration of the relationship between adherence to a diet and exercise intervention and health-related outcomes will inform the development of more cost-effective and efficacious interventions for cancer and other medical populations
Associations between Coping Skills Practice and Symptom Change in a Psychosocial Symptom Management Intervention for Lung Cancer Patients and Their Family Caregivers
Get PDFLittle research has explored the degree to which specific intervention components predict improved health outcomes for cancer patients and their family caregivers. The present study examined relations of intervention components (i.e., coping skills) to symptoms in a telephone symptom management (TSM) intervention delivered concurrently to symptomatic lung cancer patients and their family caregivers. Guided by Social Cognitive Theory (SCT) and cognitive behavioral therapy (CBT) frameworks, patient-caregiver dyads were taught coping skills including: a mindfulness exercise (i.e., noticing sounds and thoughts), pursed lips breathing, guided imagery, cognitive restructuring, and assertive communication. Symptom measures were administered at baseline and 2 and 6 weeks post-intervention. The measures assessed patient and caregiver depressive and anxiety symptoms as well as patient pain severity, distress related to breathlessness, and fatigue interference. Data were examined from patient-caregiver dyads enrolled in TSM (N = 51 dyads). Patients and caregivers were predominantly female (55% and 73%, respectively) and Caucasian (87%). The average patient was 63 years of age (SD = 8) and the average caregiver was 56 years of age (SD = 14). Seven autoregressive panel models tested relations of coping skills to symptoms. All models had at least adequate fit to the data (χ 2 ps \u3e 0.05, RMSEA values \u3c 0.06). For patients, more assertive communication practice during the intervention was related to less pain severity, fatigue interference, and depressive and anxiety symptoms at 6 weeks post-intervention. Additionally, more guided imagery practice during the intervention was related to less fatigue interference and anxiety at 6 weeks post-intervention. In contrast, more cognitive restructuring practice during the intervention was related to more distress related to breathlessness and depressive and anxiety symptoms at 6 weeks post-intervention. Similarly, more practice of a mindfulness exercise during the intervention was related to more fatigue interference and anxiety at 6 weeks post-intervention. For caregivers, more guided imagery practice was related to more anxiety at 2 weeks post-intervention. All other pathways from coping skills to symptoms at 2 and 6 weeks post-intervention were non-significant for both patients and caregivers. Findings suggest intervention effectiveness may have been reduced by competing effects of certain coping skills. For lung cancer patients, future studies should consider focusing on assertive communication and guided imagery, as these two coping skills were most consistently associated with reduced symptoms. However, more studies are needed to better understand these findings and particular caution should be used when applying CBT-based interventions that have not been validated in lung cancer populations
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
