Political ideology and the rewriting of history in fifteenth-century Flanders

Medieval views on rulers from the past were often politically instrumentalised in the service of contemporary interests. In the recent historiography on medieval Flanders, the reconstruction of how 'historical truth' changed over time to cater for topical needs has primarily been examined from the perspective of 'social' or 'communicative' memories, which were orally transmitted over a short period of time. This line of research followed the dominant 'communicative memory' paradigm. However, historians have paid far less systematic attention to the question how urban elites and state officials used histories that went farther back in time and dealt with the 'high politics' of princes and rulers to assert (rebellious) political ideologies of the moment. In this vast topic of research, historians are dealing with histories that were transmitted through manuscripts and not through oral communication. Instead of relying on the 'communicative memory' - paradigm, which allows historians to consider how the recent past has been ideologically reconstructed, this article examines how late fifteenth-century Flemish urban elites rewrote, interpolated, deformed and manipulated histories from a more distant past to shape a functional 'cultural memory' (in the sense of Jan Assmann's definition) that influenced a society's ideological vision on history. Taking the political speech of Willem Zoete (1488) and the late fifteenth-century popular and widespread Flemish historiographical Middle Dutch corpus, the Excellente Cronike van Vlaenderen, as a starting point, this article shows how rulers from the past served as a vehicle to express contemporary rebellious ideas against the regency of Maximilian of Austria, and how ideological motives and discursive strategies were deployed to advocate the ideology of the 'political contract' between the prince and his subjects, as well as the idea of the 'natural prince'

Microstructural contributions of different polyolefins to the deformation mechanisms of their binary blends

The mixing of polymers, even structurally similar polyolefins, inevitably leads to blend systems with a phase-separated morphology. Fundamentally understanding the changes in mechanical properties and occurring deformation mechanisms of these immiscible polymer blends, is important with respect to potential mechanical recycling. This work focuses on the behavior of binary blends of linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), high-density polyethylene (HDPE), and polypropylene (PP) under tensile deformation and their related changes in crystallinity and morphology. All of these polymers plastically deform by shear yielding. When unmixed, the high crystalline polyolefins HDPE and PP both exhibit a progressive necking phenomenon. LDPE initiates a local neck before material failure, while LLDPE is characterized by a uniform deformation as well as clear strain hardening. LLDPE/LDPE and LLDPE/PP combinations both exhibit a clear-cut matrix switchover. Polymer blends LLDPE/LDPE, LDPE/HDPE, and LDPE/PP show transition forms with features of composing materials. Combining PP in an HDPE matrix causes a radical switch to brittle behavior

Independent academic Data Monitoring Committees for clinical trials in cardiovascular and cardiometabolic diseases.

Data Monitoring Committees (DMCs) play a crucial role in the conducting of clinical trials to ensure the safety of study participants and to maintain a trial's scientific integrity. Generally accepted standards exist for DMC composition and operational conduct. However, some relevant issues are not specifically addressed in current guidance documents, resulting in uncertainties regarding optimal approaches for communication between the DMC, steering committee, and sponsors, release of information, and liability protection for DMC members. The Heart Failure Association (HFA) of the European Society of Cardiology (ESC), in collaboration with the Clinical Trials Unit of the European Heart Agency (EHA) of the ESC convened a meeting of international experts in DMCs for cardiovascular and cardiometabolic clinical trials to identify specific issues and develop steps to resolve challenges faced by DMCs.The main recommendations from the meeting relate to methodological consistency, independence, managing conflicts of interest, liability protection, and training of future DMC members. This paper summarizes the key outcomes from this expert meeting, and describes the core set of activities that might be further developed and ultimately implemented by the ESC, HFA, and other interested ESC constituent bodies. The HFA will continue to work with stakeholders in cardiovascular and cardiometabolic clinical research to promote these goals

Forecasting the path of a laterally propagating dike

An important aspect of eruption forecasting is predicting the path of propagating dikes. We show how lateral dike propagation can be forecast using the minimum potential energy principle. We compare theory to observed propagation paths of dikes originating at the Bárðarbunga volcano, Iceland, in 2014 and 1996, by developing a probability distribution for the most likely propagation path. The observed propagation paths agree well with the model prediction. We find that topography is very important for the model, and our preferred forecasting model considers its influence on the potential energy change of the crust and magma. We tested the influence of topography by running the model assuming no topography and found that the path of the 2014 dike could not be hindcasted. The results suggest that lateral dike propagation is governed not only by deviatoric stresses but also by pressure gradients and gravitational potential energy. Furthermore, the model predicts the formation of curved dikes around cone-shaped structures without the assumption of a local deviatoric stress field. We suggest that a likely eruption site for a laterally propagating dike is in topographic lows. The method presented here is simple and computationally feasible. Our results indicate that this kind of a model can be applied to mitigate volcanic hazards in regions where the tectonic setting promotes formation of laterally propagating vertical intrusive sheets
