In the process of life course transitions, relations between the self and the world transform, which can according to Hartmut Rosa be framed as resonance. This article focuses on the retirement transition and thus on the exit from gainful employment as one of the central spheres of our world relationship in late modernity. It raises the following questions: How do experiences of resonance change in the course of the retirement transition? Does the loss of gainful employment lead to disruptions or even the absence of resonance in terms of alienation? And which role do dimensions of social inequality, such as gender, income, education or mental health status play for resonance transformations in the transition to retirement? In terms of a reflexive mixed-methods design, this article combines quantitative panel data from the German Ageing Survey (2008–17) with a qualitative longitudinal study from the project “Doing Retiring” (2017–21). Our results show that the transition from work to retirement entails a specific “resonance choreography” that comprises a phase of disaffection (lack of resonance) at the end of one’s working life followed by a liminal phase in which people search for intensified experiences of resonance. We outline practices in which transitioning subjects seek out resonance, and the experiences they make within this process according to their social positions. We thereby find that the desire for resonance tends to be beyond intentional resonance management which manifests in products and services like coaching or wellness. In our conclusions, we discuss how resonance theory and retirement research/life course research can be fruitfully combined, but also highlight the methodological challenges the operationalization of resonance entails.
Aim: Left ventricular non-compaction (LVNC) is perceived as a rare high-risk cardiomyopathy characterized by excess left ventricular (LV) trabeculation. However, there is increasing evidence contesting the clinical significance of LV hyper-trabeculation and the existence of LVNC as a distinct cardiomyopathy. The aim of this study is to assess the association of LV trabeculation extent with cardiovascular morbidity and all-cause mortality in patients undergoing clinical cardiac magnetic resonance (CMR) scans across 57 European centers from the EuroCMR registry.
Methods and Results: We studied 822 randomly selected cases from the EuroCMR registry. Image acquisition was according to international guidelines. We manually segmented images for LV chamber quantification and measurement of LV trabeculation (as per Petersen criteria). We report the association between LV trabeculation extent and important cardiovascular morbidities (stroke, atrial fibrillation, heart failure) and all-cause mortality prospectively recorded over 404 ± 82 days of follow-up. Maximal non-compaction to compaction ratio (NC/C) was mean (standard deviation) 1.81 ± 0.67, from these, 17% were above the threshold for hyper-trabeculation (NC/C > 2.3). LV trabeculation extent was not associated with increased risk of the defined outcomes (morbidities, mortality, LV CMR indices) in the whole cohort, or in sub-analyses of individuals without ischaemic heart disease, or those with NC/C > 2.3.
Conclusion: Among 882 patients undergoing clinical CMR, excess LV trabeculation was not associated with a range of important cardiovascular morbidities or all-cause mortality over ~12 months of prospective follow-up. These findings suggest that LV hyper-trabeculation alone is not an indicator for worse cardiovascular prognosis.
The D-meson spectral density at finite temperature is obtained within a self-consistent coupled-channel approach. For the bare meson–baryon interaction, a separable potential is taken, whose parameters are fixed by the position and width of the Λc(2593) resonance. The quasiparticle peak stays close to the free D-meson mass, indicating a small change in the effective mass for finite density and temperature. Furthermore, the spectral density develops a considerable width due to the coupled-channel structure. Our results indicate that the medium modifications for the D-mesons in nucleus-nucleus collisions at FAIR (GSI) will be dominantly on the width and not, as previously expected, on the mass.
