Origins, methods and advances in qualitative meta-synthesis
Qualitative research is a broad term encompassing many methods. Critiques of the field of qualitative research argue that while individual studies provide rich descriptions and insights, the absence of connections drawn between studies limits their usefulness. In response, qualitative metaâsynthesis serves as a design to interpret and synthesise qualitative findings across individual studies. More than a broad summary, metaâsyntheses do not aim merely to summarise all available data; rather, qualitative metaâsyntheses present new perspectives on topics through interpreting findings from different qualitative studies to create âthirdâlevelâ findings for the advancement of both knowledge and theory. The diversity of opinion on qualitative metaâsynthesis is mirrored in its practice. Several different approaches to qualitative metaâsynthesis have emerged, with most connected to the metaâethnographic procedures originally outlined in 1988. This paper: (1) discusses the key philosophical and methodological issues in the literature on qualitative metaâsynthesis, (2) highlights key methods that are used in qualitative metaâsynthesis, and (3) offers an overview of where the field is going. Examples from the last four years of qualitative metaâsyntheses highlight some of this design's current contributions and future usefulness for research in the field of education

Racial and Imperial Thinking in International Theory and Politics: Truman, Attlee and the Korean War
- Connects the background ideas of race and empire to world politics
- Uses case of Truman and Attlee in the Korean War
- Argues that liberal-realist internationalistsâ assumptions about the US-led post-war order obscure those background ideas and fail to understand the character of the post-war order
- Argues liberal-realist internationalism is akin to a legitimating ideology rather than an explanatory theory
- Argues that such failings render liberal internationalism inadequate to explain or prescribe ways for the United States/West to manage the ârise of the restâ today
This article connects the background ideas of race and empire to world politics by looking at the world views and actions of Truman and Attlee in the Korean War. The article argues that liberal-realist internationalistsâ assumptions about the US-led post-war order obscure those background ideas and fail to understand the character of the post-war order. I consider two kinds of âbackground ideasââpolicy-makersâ and those embedded in liberal internationalism. Put together, these ideas render liberal-realist internationalism akin to a legitimating ideology rather than an explanatory theory. More broadly, and in the longer run, such failure to comprehend the character of the post-war order, and the roles of race, empire and periphery war in it, renders the theory inadequate to explain or prescribe ways for the United States/West to manage the ârise of the restâ today
The perceived impact of location privacy: A web-based survey of public health perspectives and requirements in the UK and Canada
<p>Abstract</p> <p>Background</p> <p>The "place-consciousness" of public health professionals is on the rise as spatial analyses and Geographic Information Systems (GIS) are rapidly becoming key components of their toolbox. However, "place" is most useful at its most precise, granular scale â which increases identification risks, thereby clashing with privacy issues. This paper describes the views and requirements of public health professionals in Canada and the UK on privacy issues and spatial data, as collected through a web-based survey.</p> <p>Methods</p> <p>Perceptions on the impact of privacy were collected through a web-based survey administered between November 2006 and January 2007. The survey targeted government, non-government and academic GIS labs and research groups involved in public health, as well as public health units (Canada), ministries, and observatories (UK). Potential participants were invited to participate through personally addressed, standardised emails.</p> <p>Results</p> <p>Of 112 invitees in Canada and 75 in the UK, 66 and 28 participated in the survey, respectively. The completion proportion for Canada was 91%, and 86% for the UK. No response differences were observed between the two countries. Ninety three percent of participants indicated a requirement for personally identifiable data (PID) in their public health activities, including geographic information. Privacy was identified as an obstacle to public health practice by 71% of respondents. The overall self-rated median score for knowledge of privacy legislation and policies was 7 out of 10. Those who rated their knowledge of privacy as high (at the median or above) also rated it significantly more severe as an obstacle to research (<it>P </it>< 0.001). The most critical cause cited by participants in both countries was bureaucracy.</p> <p>Conclusion</p> <p>The clash between PID requirements â including granular geography â and limitations imposed by privacy and its associated bureaucracy require immediate attention and solutions, particularly given the increasing utilisation of GIS in public health. Solutions include harmonization of privacy legislation with public health requirements, bureaucratic simplification, increased multidisciplinary discourse, education, and development of toolsets, algorithms and guidelines for using and reporting on disaggregate data.</p
Omega-3 fatty acids in high-risk cardiovascular patients: a meta-analysis of randomized controlled trials
<p>Abstract</p> <p>Background</p> <p>Multiple randomized controlled trials (RCTs) have examined the cardiovascular effects of omega-3 fatty acids and have provided unexplained conflicting results. A meta-analysis of these RCTs to estimate efficacy and safety and potential sources of heterogeneity may be helpful.</p> <p>Methods</p> <p>The Cochrane library, MEDLINE, and EMBASE were systematically searched to identify all interventional trials of omega-3 fatty acids compared to placebo or usual diet in high-risk cardiovascular patients. The primary outcome was all-cause mortality and secondary outcomes were coronary restenosis following percutaneous coronary intervention and safety. Meta-analyses were carried out using Bayesian random-effects models, and heterogeneity was examined using meta-regression.</p> <p>Results</p> <p>A total of 29 RCTs (n = 35,144) met our inclusion criteria, with 25 reporting mortality and 14 reporting restenosis. Omega-3 fatty acids were not associated with a statistically significant decreased mortality (relative risk [RR] = 0.88, 95% Credible Interval [CrI] = 0.64, 1.03) or with restenosis prevention (RR = 0.89, 95% CrI = 0.72, 1.06), though the probability of some benefit remains high (0.93 and 0.90, respectively). However in meta-regressions, there was a >90% probability that larger studies and those with longer follow-up were associated with smaller benefits. No serious safety issues were identified.</p> <p>Conclusions</p> <p>Although not reaching conventional statistical significance, the evidence to date suggests that omega-3 fatty acids may result in a modest reduction in mortality and restenosis. However, caution must be exercised in interpreting these benefits as results were attenuated in higher quality studies, suggesting that bias may be at least partially responsible. Additional high quality studies are required to clarify the role of omega-3 fatty acid supplementation for the secondary prevention of cardiovascular disease.</p

Recent progress in understanding and predicting Atlantic decadal climate variability
Recent Atlantic climate prediction studies are an exciting new contribution to an extensive body of research on Atlantic decadal variability and predictability that has long emphasized the unique role of the Atlantic Ocean in modulating the surface climate. We present a survey of the foundations and frontiers in our understanding of Atlantic variability mechanisms, the role of the Atlantic Meridional Overturning Circulation (AMOC), and our present capacity for putting that understanding into practice in actual climate prediction systems

Inflammatory biomarkers in Alzheimer's disease plasma
Introduction: Plasma biomarkers for Alzheimer's disease (AD)diagnosis/stratification are a âHoly Grailâ of AD research and intensively sought; however, there are no well-established plasma markers. Methods: A hypothesis-led plasma biomarker search was conducted in the context of international multicenter studies. The discovery phase measured 53 inflammatory proteins in elderly control (CTL; 259), mild cognitive impairment (MCI; 199), and AD (262)subjects from AddNeuroMed. Results: Ten analytes showed significant intergroup differences. Logistic regression identified five (FB, FH, sCR1, MCP-1, eotaxin-1)that, age/APOΔ4 adjusted, optimally differentiated AD and CTL (AUC: 0.79), and three (sCR1, MCP-1, eotaxin-1)that optimally differentiated AD and MCI (AUC: 0.74). These models replicated in an independent cohort (EMIF; AUC 0.81 and 0.67). Two analytes (FB, FH)plus age predicted MCI progression to AD (AUC: 0.71). Discussion: Plasma markers of inflammation and complement dysregulation support diagnosis and outcome prediction in AD and MCI. Further replication is needed before clinical translation
Regulator Vulnerabilities to Political Pressure and Political Tie Intensity: The Moderating Effects of Regulatory and Political Distance
This study applies the institution-based view and neo-institutional theory in addressing how managerial perceptions of regulator vulnerabilities to political pressure, and institutional distance, influence intensification of political ties. Our analysis of 181 wholly owned foreign subsidiary (WOFSs) operating in the Philippines suggests that managerial perceptions of regulator vulnerability to political pressures positively enhance the intensification of political ties. Our results also reveal that regulatory distance and, more importantly, the simultaneous presence of political and regulatory distance diminish the positive relationship between managerial perceptions of regulator vulnerability to political pressures and a WOFSâs propensity to enhance the intensification of political ties. Managerial implications and future research directions are discusse
