Process-evaluation of tropospheric humidity simulated by general circulation models using water vapor isotopic observations: 2. Using isotopic diagnostics to understand the mid and upper tropospheric moist bias in the tropics and subtropics

Evaluating the representation of processes controlling tropical and subtropical tropospheric relative humidity (RH) in atmospheric general circulation models (GCMs) is crucial to assess the credibility of predicted climate changes. GCMs have long exhibited a moist bias in the tropical and subtropical mid and upper troposphere, which could be due to the mis-representation of cloud processes or of the large-scale circulation, or to excessive diffusion during water vapor transport. The goal of this study is to use observations of the water vapor isotopic ratio to understand the cause of this bias. We compare the three-dimensional distribution of the water vapor isotopic ratio measured from space and ground to that simulated by several versions of the isotopic GCM LMDZ. We show that the combined evaluation of RH and of the water vapor isotopic composition makes it possible to discriminate the most likely cause of RH biases. Models characterized either by an excessive vertical diffusion, an excessive convective detrainment or an underestimated in situ cloud condensation will all produce a moist bias in the free troposphere. However, only an excessive vertical diffusion can lead to a reversed seasonality of the free tropospheric isotopic composition in the subtropics compared to observations. Comparing seven isotopic GCMs suggests that the moist bias found in many GCMs in the mid and upper troposphere most frequently results from an excessive diffusion during vertical water vapor transport. This study demonstrates the added value of water vapor isotopic measurements for interpreting shortcomings in the simulation of RH by climate models

Using the Electronic Health Record in Nursing Research: Challenges and Opportunities

Changes in the patient record from the paper to the electronic health record format present challenges and opportunities for the nurse researcher. Current use of data from the electronic health record is in a state of flux. Novel data analytic techniques and massive data sets provide new opportunities for nursing science. Realization of a strong electronic data output future relies on meeting challenges of system use and operability, data presentation, and privacy. Nurse researchers need to rethink aspects of proposal development. Joining ongoing national efforts aimed at creating usable data output is encouraged as a means to affect system design. Working to address challenges and embrace opportunities will help grow the science in a way that answers important patient care questions

Religion, securitization and anti-immigration attitudes: the case of Greece

This article revisits securitization theory of the Copenhagen School by addressing an empirical overemphasis on political actors and offering a quantitative extension to typically qualitative assessments of the theory. Using Greece as a case study, it explores the dynamics of competition and the relative discursive power of two actors, political and religious elites, regarding migration. After first documenting a divergence in the two actors’ rhetoric through discourse analysis, it proceeds to measure the relative impact of their discourses on public immigration attitudes, employing structural equation modelling of European Social Survey data. Findings demonstrate that exposure to the securitizing religious discourse through church attendance immunizes citizens from the softening effect of the political message. This, in turn, explains the survival of the security frame on migration in Greece, even as political elites begin to move towards the desecuritized pole of the continuum. Crucially, the analysis of this case suggests that a methodological synthesis of qualitative and quantitative research methods to study securitization is possible despite limitations. The authors call for greater efforts to combine the two methods which would allow for a better understanding of securitization and desecuritization processes
