Transversality of the logarithmic divergences in the Classical Finite Temperature SU(N) Self-Energy

We show that the logarithmic divergences that appear in the classical approximation of the finite temperature SU(N) self-energy are transverse. We use the Ward identities in linear gauges and the fact that the superficial degree of divergence d of a classical diagram only depends on the number of loops l via d=2-l. We comment on the relevance of this result to the construction of a low-energy effective theory beyond HTLs.Comment: 5 pages, 1 figure, REVTE

Uncovering communication strategies used in language-discordant consultations with people who are migrants: Qualitative interviews with healthcare providers

Background: Global migration has led to a sharp increase in the number of language-discordant consultations (LDCs) in healthcare. Evidence on how healthcare providers (HCPs) meet migrant patients' needs while mitigating language barriers is lacking.Design: Using purposive and snowball sampling, we recruited twenty-seven Dutch HCPs (Mage = 45.07, SD = 11.46) and conducted semi-structured interviews to collect qualitative, open-ended data for identifying the communication strategies used with migrant patients in LDCs. We analysed the transcripts using deductive and inductive approaches (e.g., constant comparative method from Grounded Theory). Final pattern codes (i.e., key themes) were discussed among the research team until mutual agreement had been achieved.Results: Five key themes emerged from the analyses: HCPs often ‘got-by’ with (1) instrumental and (2) affective communication strategies used in language-concordant consultations to start medical consultations. When some instrumental communication strategies were deemed ineffective (e.g., lingua franca, gesturing, etc.) to bridge language barriers, HCPs turned to (3) incorporating digital tools (e.g., Google Translate). When HCPs were unable to communicate with migrant patients at all, (4) informal, ad-hoc and professional interpreters were involved. Finally, HCPs often (5) involved additional support to engage migrant patients to engage in treatment-related behaviours.Discussion and Conclusions: Our results highlight the importance of raising awareness among HCPs about using various combinations of different strategies. The development of a guideline indicating the optimal combination of communication strategies for different medical consultation goals may be useful in reshaping the current communication behaviour of HCPs in LDCs.Patient or Public Contribution: HCPs were the study population involved in this qualitative study. Refugee health advisors, general practitioners and linguistic specialists (i.e., members of the Right2Health consortium) with experience with the Dutch healthcare system were involved throughout the development of this research. This includes a review of the research question, participant information sheet and interview topic guide as well as providing interpretations of the data and feedback to this manuscript

Testing the effects on information use by older versus younger women of modality and narration style in a hospital report card

BACKGROUND: Hospital report cards (HRCs) are usually presented in a textual and factual format, likely hampering information processing. OBJECTIVE: This study aimed to investigate the effects of audiovisual and narrative information in HRCs on user responses, and to test differences between older and younger women. DESIGN: A 2 (modality [textual vs. audiovisual]) × 3 (narration style [factual vs. process narrative vs. experience narrative]) online experiment was conducted. Information about breast cancer care was used as a case example. Age (younger [<65] vs. older [≥65]) was included as a potential effect modifier. SETTING AND PARTICIPANTS: A total of 631 disease‐naïve women (M (age) = 56.06) completed an online survey. The outcomes were perceived cognitive load, satisfaction, comprehension, information recall and decisional conflict. Data were analysed using AN(C)OVAs. RESULTS: Audiovisual (vs. textual) information resulted in higher information satisfaction across age groups, but was associated with lower comprehension in older women. An experience narrative (vs. factual information) increased satisfaction with attractiveness and emotional support of the information only in older women. A three‐way interaction effect was found, suggesting that older women were most satisfied with the comprehensibility of audiovisual factual or textual process narrative information. Younger women were most satisfied with the comprehensibility of audiovisual process narrative or textual factual information. DISCUSSION AND CONCLUSION: Audiovisual and narrative information in an HRC showed beneficial effects on satisfaction measures. In particular, audiovisual information could be incorporated into HRCs to increase satisfaction with information. PUBLIC CONTRIBUTION: Lay persons helped in optimizing the visuals used in the stimulus materials by checking for clarity
