Mapping the qualitative evidence base on the use of research evidence in health policy-making: a systematic review

BACKGROUND; : The use of research evidence in health policy-making is a popular line of inquiry for scholars of public health and policy studies, with qualitative methods constituting the dominant strategy in this area. Research on this subject has been criticized for, among other things, disproportionately focusing on high-income countries; overemphasizing 'barriers and facilitators' related to evidence use to the neglect of other, less descriptive concerns; relying on descriptive, rather than in-depth explanatory designs; and failing to draw on insights from political/policy studies theories and concepts. We aimed to comprehensively map the global, peer-reviewed qualitative literature on the use of research evidence in health policy-making and to provide a descriptive overview of the geographic, temporal, methodological, and theoretical characteristics of this body of literature.; METHODS; : We conducted a systematic review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched nine electronic databases, hand-searched 11 health- and policy-related journals, and systematically scanned the reference lists of included studies and previous reviews. No language, date or geographic limitations were imposed.; RESULTS; : The review identified 319 qualitative studies on a diverse array of topics related to the use of evidence in health policy-making, spanning 72 countries and published over a nearly 40 year period. A majority of these studies were conducted in high-income countries, but a growing proportion of the research output in this area is now coming from low- and middle-income countries, especially from sub-Saharan Africa. While over half of all studies did not use an identifiable theory or framework, and only one fifth of studies used a theory or conceptual framework drawn from policy studies or political science, we found some evidence that theory-driven and explanatory (eg, comparative case study) designs are becoming more common in this literature. Investigations of the barriers and facilitators related to evidence use constitute a large proportion but by no means a majority of the work in this area.; CONCLUSION; : This review provides a bird's eye mapping of the peer reviewed qualitative research on evidence-to-policy processes, and has identified key features of - and gaps within - this body of literature that will hopefully inform, and improve, research in this area moving forward

Photodefinition of channel waveguide in electro-optic polymer

Polymers with optically active nonlinear chromophores have been shown to have a promising future in low cost and high speed electro–optic device applications. However, a main question of concern is the photochemical stability of the chromophores for long term application. The chromophore TCVDPA with a benzene bridge between a tricyanovinyl acceptor and an amino donor has been reported to have high photochemical stability combined with high electro-optic activity. In the current work direct waveguide definition of the host polymer SU-8, a negative photoresist, containing this chromophore by masked UV exposure followed by development, has been demonstrated. This was possible by utilizing the chromophore low absorption window in the UV region that allows crosslinking of the host polymer by exposing to UV light followed by thermal curing

Highly Promising Method for the Decontamination of Europium from Americium Using an Extraction Chromatography Resin Containing a Tripodal Diglycolamide and SO₃Ph-BTP as Eluent

Separation of Am3+ from Eu3+ was demonstrated by extraction column chromatography using a tripodal diglycolamide ligand (T-DGA). A clean separation was achieved by selective complexation of Am3+ in the feed with 2,6-bis(5,6-di(sulfophenyl)-1,2,4-triazin-3-yl)pyridine (SO3Ph-BTP) with a separation factor of about 2000. The extraction chromatography resin material with particle size in the range of 175-250 μm contained only 7.4% T-DGA ligand (53 μmol/g) and is one of the most efficient materials used for this purpose until date. Parameters such as feed acidity and SO3Ph-BTP concentration were varied, while keeping the other parameters constant for getting the best optimized condition for the separation of Am3+ from Eu3+ ions. The optimized feed condition was 0.1 M HNO3 containing 10 mM SO3Ph-BTP for the clean separation of Am3+ from the Eu3+ fraction. In the feed solution containing Eu3+ and Am3+, the latter was complexed with SO3Ph-BTP and, therefore, was not retained on the column, whereas the uncomplexed Eu3+ could be efficiently held onto the column. Finally, the loaded Eu3+ from the column was eluted with 0.1 M HEDTA (N-(2-hydroxyethyl)ethylenediamine-N,N′,N′-triacetic acid), giving a sharp and narrow elution curve. The radiation stability of the resin was excellent up to 1000 KGy gamma dose, and an identical separation efficiency of the resin was noted with the irradiated resin column, as was obtained with the pristine resin.</p
