The Logics of and Strategies to Enhance Generalization of Mixed Methods Research Findings
No full textDecision tree for identifying pertinent integration procedures and joint displays in mixed methods research
Full text linkAims: To propose a decision tree for identifying appropriate integration procedures and joint displays for achieving integration in mixed methods studies. Design: A methodological discussion. Data Sources: Methodological literature including mixed methods textbooks, methodological reviews and studies published in the last 10 years (2012–2022). Implications for Nursing: Mixed methods are instrumental to study complex nursing care processes and health-human phenomena. Nurse researchers can use this decision tree to choose the most appropriate integration procedures to overcome the integration challenge when designing and conducting mixed methods nursing studies. Conclusion: Integration procedures and joint displays are the most widely used methods for tackling the integration challenge in mixed methods research (MMR). The multifaceted and contingent nature of these methods are beneficial for their tailored and adapted use at the data collection, analysis, interpretation and reporting levels. The use of the most pertinent integration procedures and joint displays is critical for ensuring quality in MMR. Impact: A growing methodological literature on MMR offers a wide range of integration procedures and techniques. Therefore, choosing appropriate integration procedures and analysis methods can be challenging for nurse researchers interested in conducting mixed methods studies. A decision tree is developed outlining 14 integration procedures and their corresponding mixed methods designs, purposes and joint displays. Examples of mixed methods studies in the discipline of nursing are presented to illustrate the implementation of the integration procedures. The decision tree can serve as a straightforward methodological tool for decision making in MMR. Nurse researchers can effectively use this decision tree for research and teaching purposes.

A Placebo-Controlled Trial of PCI for Stable Angina
No full textIn the editorial accompanying the article by Rajkumar and colleagues (Dec. 21 issue)1 on the results of the ORBITA-2 trial involving the use of percutaneous coronary intervention (PCI) in patients with stable angina, White2 begins with a flawed premise: “The primary aim of treating patients with stable angina is to decrease symptoms and improve quality of life.” That is not the primary aim of treating these patients. Relieving angina is important, but the real priority in the management of stable angina is the provision of appropriate medical therapy to reduce the risk of myocardial infarction and sudden death. Thus, we continue our orbit around PCI. Many patients undergo stent implantation at the same time that we have not made the systematic changes that are necessary to ensure that every patient receives appropriate medical therapy. That is what must be changed.
The follow-up of the ORBITA-2 trial lasted only 12 weeks, and the between-group differences in the frequency of angina were modest. Five years into the COURAGE trial,3 74% of patients in the PCI group and 72% of those in the medical-therapy group were free from angina. The new orbit? Appropriate medical therapy first, followed by PCI if angina is not sufficiently relieved
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
Building integrated photovoltaic in heritage contexts award: an overview of best practices in Italy and Switzerland
No full textThe widespread of photovoltaic (PV) technology has led to high-performance products and systems during recent years. This allowed an expansion of PV application scope enormously, especially in listed buildings and natural landscapes subject to different forms of protection. Despite that, there are still many doubts and supposed limitations regarding their applicability by stakeholders involved in the construction process. Best practices and applications help to spread the applicability of the PV technology in historic buildings, conservation areas and cultural landscapes. For this purpose, the "Special Award for Solar Architecture in Heritage Contexts" developed within the framework of the Interreg project "BIPV meets history" aims at awarding the more significant Italian-Swiss BIPV case studies in historical buildings and heritage landscapes. This research work offers an overview of the 85 projects nominated for the award. The best projects are described and analysed to define the state of the art and criteria and technologies used for PV integration in architecturally sensitive areas to raise awareness to all stakeholders involved. The trade-off between cutting-edge technology and design expertise can lead to the perfect balance between historic buildings or high-value
contexts preservation and contemporary needs and lifestyles
