The quantum anomaly is written alternatively into a form violating conservation laws or as non-gauge invariant currents seen explicitly on the example of chiral anomaly. By reinterpreting the many-body averaging, the connection to Pauli–Villars regularization is established which gives the anomalous term a new interpretation as arising from quantum fluctuations by many-body correlations at short distances. This is exemplified using an effective many-body quantum potential which realizes quantum Slater sums by classical calculations. It is shown that these quantum potentials avoid the quantum anomaly but approach the same anomalous result by many-body correlations. Consequently, quantum anomalies might be a shortcut way of single-particle field theory to account for many-body effects. This conjecture is also supported since the chiral anomaly can be derived by a completely conserving quantum kinetic theory. A measure for the quality of quantum potentials is suggested to describe these quantum fluctuations in the mean energy. The derived quantum potentials might be used to describe quantum simulations in classical terms.
Background: Currently, to the best of our knowledge, no findings exist concerning the needs of professionals in specialized pediatric palliative care (PPC) regarding electronic health records (EHRs). Several studies have highlighted benefits concerning the use of EHRs in pediatrics. However, usability is strongly affected by the degree of adaptivity to the context of application. The aim of this study is to examine the needs of professionals concerning an EHR in the specialized PPC inpatient and outpatient settings. Methods: A qualitative research design was chosen to address the complex aspects of user demands. Focus group interviews and semi-structured one-on-one interviews were conducted with PPC professionals. N = 23 participants from inpatient and N = 11 participants from outpatient settings of specialized PPC representing various professions took part in the study. Results: The findings could be grouped into four categories: (1) attitude towards the current methods of documentation, (2) attitude towards electronic documentation in general, (3) general requirements for an EHR, and (4) content requirements for an EHR. Conclusions: Professionals in specialized PPC expect and experience many benefits of using electronic documentation. Their requirements for an EHR for inpatient and outpatient settings of PPC are largely consistent with EHRs for pediatrics. However, individual specifications and adaptations are necessary for this particular setting.
This paper presents a seminar concept for the development of communication competence in pre-service vocational education teachers with the aid of video annotations, feedback, and peer microteaching. The seminar is offered within a teacher training program for students taking a master’s degree (MEd) in vocational education at the FH Münster University of Applied Sciences, Germany, and has been conducted three times. The advantages of the seminar concept are manifold. On the one hand, we create a learning environment in which students individually prepare and conduct five peer microteaching lessons in a row and receive prompt and constructive peer feedback on every performance. On the other hand, the quality of feedback improves so that our students are professional feedback providers by the end of the seminar. The provision of teacher feedback alone does not help our students become successful feedback providers. Nor, given the resources available at the university, is it a realistic alternative in terms of time constraints. In addition, due to recordings, the students gain a better insight into their teaching skills since their lessons can be observed and approached from an outside perspective.
Experimental results are presented of a test of the theory of local turbulent heat transfer measurements proposed by Mocikat and Herwig in 2007. A miniaturized multi-layer heat transfer sensor was developed and employed in this study. The new heat transfer sensor was designed to work in air and liquids, and this capability enabled the simultaneous investigation of different Prandtl numbers. Two basic configurations, namely the flow past a blunt plate and the flow past an inclined square cylinder, were investigated in test sections of wind and water tunnels. Convective heat transfer coefficients were obtained through conventional testing (i.e., employing thoroughly heated test objects) and using the new miniaturized sensor approach (i.e., utilizing cold test objects without heating). The main prediction of the Mocikat-Herwig theory that a specific thermal adjustment coefficient of the employed actual miniaturized heat transfer sensor should exist in the fully turbulent flow regime was proven for developed two-dimensional flow. The observed effect of the Prandtl number on this coefficient was in good agreement with the prediction of the asymptotic expansion method. The square cylinder results indicated the inherent limits of the local turbulent heat transfer measurement approach, as suggested by Mocikat and Herwig.
As a salutogenic concept, “consumption corridors” aims to support what is necessary for sustainable wellbeing to be achieved in relation to the Earth system, with a deep consideration for justice and equity. Living in consumption corridors is a representation of everyday life whereby people live within limits, so that all people – now and in the future – can access what is needed to live a good life. In this special issue, a series of scholars and practitioners have come together to further develop the concept, engage with its ethodological implications, and relate it to consumption domains and policy implications. We begin by introducing how the concept emerged, in relation to the complexity of grappling with the societal transformations required for achieving more sustainable forms of consumption. We then present the different contributions, which demonstrate the importance of considering both maximum and minimum consumption standards, the relevance of human-need theories, as well as the difference between achieving wellbeing and the means necessary for doing so. We conclude by opening up to areas that merit further deliberation: how to relate consumption corridors to everyday-life dynamics, but also to the critical question of power relations at play in implementing consumption corridors.
Adhärenz digitaler Interventionen im Gesundheitswesen: Definitionen, Methoden und offene Fragen
(2021)
AbstractMany digital interventions rely on the participation of their users to have a positive impact. In various areas it can be observed that the use of digital interventions is often reduced or fully discontinued by the users after a short period of time. This is seen as one of the main factors that can limit the effectiveness of digital interventions. In this context, the concept of adherence to digital interventions is becoming increasingly important. Adherence to digital interventions is roughly defined as “the degree to which the user followed the program as it was designed,” which can also be paraphrased as “intended use” or “use as it is designed.” However, both the theoretical–conceptual and practical discussions regarding adherence to digital interventions still receive too little attention.The aim of this narrative review article is to shed more light on the concept of adherence to digital interventions and to distinguish it from related concepts. It also discusses the methods and metrics that can be used to operationalize adherence and the predictors that positively influence adherence. Finally, needs for action to better address adherence are considered critically.
