Internationale Rekrutierung und Migration von Ärztinnen, Ärzten und Personal in Gesundheitsfachberufen: ein qualitatives Scoping Review der Public Health Literatur

Background

The international recruitment and migration of health workers has long been debated in the health policy literature. This study assesses to what extent the ethics of international recruitment are targeted in existing public health peer-reviewed literature, with a focus on concepts and in-depth consideration within articles. It further critically discusses hidden implications of this discourse regarding equity-creating health policy.

Methods

We conducted a qualitative scoping literature review searching the databases PubMed and Web of Science. Articles were assessed for quality using the Critical Appraisal Skills Program (CASP) checklist for qualitative research. Drawing on a thematic analysis approach, common themes across the sample were identified, coded and analyzed.

Results

A total of 17 articles were included in the analysis after searches and quality appraisal. These articles predominantly targeted nursing professions and physicians, and were written mainly by authors working in the Global North. Thematic analysis revealed that ethics are generally discussed in connection with overviews regarding the situation of health systems as well as regarding inequities between countries. Their focus lies more on migration between countries than between regions within a country. Proposed solutions are usually of an economic nature and range from global financial equalization between countries to national improvements in working conditions. Creative evaluation schemes for these solutions are rarely discussed in depth. Overall, the academic ethics discussion focuses predominantly on the health systems level, and views migration of health workers as problematic.

Conclusions

Our results suggest that academic research operates and aims to inform policy within the current system, without necessarily proposing fundamental changes to the status quo. Thus, an ethics discourse of health workforce recruitment may serve to increase awareness of inequalities without supporting radical change. Further research into intersectional aspects of health worker migration, including gender and ethnicity, may be useful for the discussion on inequities.

Quantifying ambivalence towards sustainable intensification: an exploration of the UK public’s values

Sustainable intensification (SI) has been proposed as a solution to meeting the challenge of feeding a growing global population under increasing land pressure. This paper explores the level of ambivalence felt towards SI and towards experts promoting SI based solutions to meet food security. A web-based experiment was conducted with 600 respondents who had varying degrees of knowledge about food security issues. We found a diversity of public ambivalence towards sustainable intensification and a high level of felt ambivalence towards experts promoting SI as a solution to global food security. High levels of ambivalence towards experts seemed to influence how messages on global food security were accepted. Moreover, within the respondents here sustainable consumption and greater equity ranked higher than production based sustainable intensification solutions. This paper represents the first application of the psychological construct of ambivalence applied to the topic of sustainable intensification and we argue this helps to localise the debate around SI as it offers the opportunity to capture or disentangle responses towards food security issues.     

It’s not all written on the robot’s face

Past work on creating robots that can make convincing emotional expressions has concentrated on the quality of those expressions, and on assessing people’s ability to recognize them in neutral contexts, without any strong emotional valence. It would be interesting to find out whether observers’ judgments of the facial cues of a robot would be affected by a surrounding emotional context. This paper takes its inspiration from the contextual effects found on our interpretation of the expressions on human faces and computer avatars, and looks at the extent to which they also apply to the interpretation of the facial expressions of a mechanical robot head. The kinds of contexts that affect the recognition of robot emotional expressions, the circumstances under which such contextual effects occur, and the relationship between emotions and the surrounding situation, are observed and analyzed. Design implications for believable emotional robots are drawn.     

Superparamagnetic Ag@Co‐Nanocomposites on Granulated Cation Exchange Polymeric Matrices with Enhanced Antibacterial Activity for the Environmentally Safe Purification of Water

Cation exchange polymeric matrices are widely used in water treatment protocols to reduce the mineral content of hard waters, even for human consumption. However, they are not antibacterial and flowing bacteria can be trapped in their structures and proliferate, thus acting as microbial contamination sources. Here, Ag@Co‐nanoparticles (Ag@Co‐NPs) with a low‐cost superparamagnetic Co⁰‐core and an antibacterial Ag‐shell are synthesized on granulated cation exchange polymeric matrices under soft reaction conditions. The presence of these NPs provides the final nanocomposite (NC) with additional functionalities (superparamagnetism and antibacterial activity) making it ideal for water purification applications. Ag@Co‐NPs are synthesized in situ on four cation exchange polymeric matrices containing either strong (sulfonic) or weak (carboxylic) acid functional groups homogeneously distributed (C‐type) or concentrated on an external shell (SST‐type) by the intermatrix synthesis (IMS) method. The NCs are characterized (metal content, NP size and distribution, metal oxidative state, and metal release) and evaluated for water purification applications.     

Effect of rheology and humic acids on the transport of environmental fluids: Potential implications for soil remediation revealed through microfluidics

This study investigated the potential effect of shear rheology and humic acids (HA) on the subsurface transport of polymeric fluids used for the remediation of contaminants. Polymeric fluids were prepared with guar, scleroglucan, and carboxymethyl cellulose (CMC). Guar fluids can be used to suspend reactive particles for contaminant degradation. Fluids prepared with 2.5 g/L of guar in water were viscous, and the crosslinker borax (1 g/L) made them viscoelastic. Microfluidics experiments showed that the increase in elasticity blocked the flow of guar in 350 μm channels. Guar, CMC, or scleroglucan fluids containing sodium thiosulfate can be used to trap toxic Cr(VI) in the subsurface and reduce it to harmless Cr(III). Trapping of Cr(VI) is achieved by the gelation of the fluids upon contact with chromium. Before mixing with chromium, HA did not affect the flow of CMC, guar, and scleroglucan in microfluidic channels. Quartz-crystal microbalance with dissipation monitoring experiments indicates that HA reduced sorption of guar onto silica, potentially promoting the transport of guar fluids in sandy aquifers. While HA slightly decreased the rate of gelation of CMC and scleroglucan upon contact with chromium, it did not affect the fast gelation rate of guar. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
