En replaçant les travaux de Philippe Walter dans les cadres historique et théorique des analyses bachelardiennes et durandiennes sur l’imaginaire, Blanca Solares met en évidence les apports spécifiques de ses thèses, tant du point de vue méthodologique que du point de vue idéologique. Cette entreprise de reconstruction des présupposés conceptuels de Philippe Walter permet de souligner l’importance d’une réévaluation en profondeur d’un imaginaire médiéval trop souvent compris à l’aune d’une conception simplificatrice de la christianisation, tout en montrant la nécessité d’une (...) approche nuancée et renouvelée des sources traditionnelles. By putting the work of Philippe Walter in the historical and theoretical contexts of the Bachelard and Durand’s analysis on the imaginary, Blanca Solares highlights the specific contributions of his theses, both from methodological and ideological points of view. This reconstruction effort on the conceptual presuppositions of Philippe Walter serves to accentuate the importance of a thorough revaluation of a medieval imaginary too often understood, at the beginning of a simplified design to the Christianization, while showing the need for a nuanced and renewed approach to traditional sources. Al situar las investigaciones de Philippe Walter dentro del marco histórico-teórico de los análisis de Bachelard y Durand sobre el imaginario, Blanca Solares evidencia sus aportes específicos, tanto metodológicos como ideológicos. Esta labor de reconstrucción de los fundamentos conceptuales de Philippe Walter muestra cuánto importa cambiar el enfoque al imaginario medieval empobrecido por unas aproximaciones a la cristianización demasiado simplificadoras y justifica plenamente una aproximación renovada y fina a las fuentes tradicionales.

Zusammenfassung Die vorliegende qualitative Fallanalyse befasst sich mit dem Einstieg junger Menschen in die Szene der sogenannten Ultras und dessen Bedingungsfaktoren. Dazu wurden zwei problemzentrierte Interviews mit einer weiblichen Anwärterin und einem männlichen Anwärter auf eine Mitgliedschaft in einer Ultra-Gruppe geführt. Es wird den Fragen nachgegangen, wie die AspirantInnen den Einstieg bewältigen und welche Bedeutung der Kategorie des Geschlechts zukommt. Dabei werden die je subjektiven Erwartungen, Prozesse, Bedeutungsgehalte und Konflikte analysiert. Es zeigt sich, dass trotz einiger Parallelen die Einstiegsprozesse sehr (...) unterschiedlich verlaufen. Dabei kommt insbesondere den Kategorien des Geschlechts, des Beziehungsstandes sowie des Alters zentrale Bedeutung zu. Der Beitrag erweitert damit die Forschung über Fußballfangruppen um den wichtigen Prozess des Szenezugangs. (shrink)

BackgroundFunctional neurodiagnostics could allow researchers and clinicians to distinguish more accurately between the unresponsive wakefulness syndrome and the minimally conscious state. It remains unclear how it informs surrogate decision-making.ObjectiveTo explore how the next of kin of patients with disorders of consciousness interpret the results of a functional neurodiagnostics measure and how/why their interpretations influence their attitudes towards medical decisions.Methods and SampleWe conducted problem-centered interviews with seven next of kin of patients with DOC who had undergone a functional HD-EEG examination at (...) a neurological rehabilitation center in Germany. The examination included an auditory oddball paradigm and a motor imagery task to detect hidden awareness. We analyzed the interview transcripts using structuring qualitative content analysis.ResultsRegardless of the diagnostic results, all participants were optimistic of the patients’ meaningful recovery. We hypothesize, that participants deal with the results of examinations according to their belief system. Thus, an unfavorable evaluation of the patient’s state had the potential to destabilize the participant’s belief system. To re-stabilize or to prevent the destabilization of their belief system, participants used different strategies. Participants accepted a “positive” HD-EEG result since it stabilized their belief system.ConclusionWe hypothesize, that a group of next of kin of patients with DOC deals with functional neurodiagnostics results on the basis of the result’s value and their high hope that the patient will recover meaningfully. A psychological mechanism seems to moderate the impact of functional neurodiagnostics on surrogate treatment decisions. (shrink)

Objective: Gait adaptation to environmental challenges is fundamental for independent and safe community ambulation. The possibility of precisely studying gait modulation using standardized protocols of gait analysis closely resembling everyday life scenarios is still an unmet need.Methods: We have developed a fully-immersive virtual reality environment where subjects have to adjust their walking pattern to avoid collision with a virtual agent crossing their gait trajectory. We collected kinematic data of 12 healthy young subjects walking in real world and in the VR (...) environment, both with and without the VA perturbation. The VR environment closely resembled the RW scenario of the gait laboratory. To ensure standardization of the obstacle presentation the starting time speed and trajectory of the VA were defined using the kinematics of the participant as detected online during each walking trial.Results: We did not observe kinematic differences between walking in RW and VR/A-, suggesting that our VR environment per se might not induce significant changes in the locomotor pattern. When facing the VA all subjects consistently reduced stride length and velocity while increasing stride duration. Trunk inclination and mediolateral trajectory deviation also facilitated avoidance of the obstacle.Conclusions: This proof-of-concept study shows that our VR/A+ paradigm effectively induced a timely gait modulation in a standardized immersive and realistic scenario. This protocol could be a powerful research tool to study gait modulation and its derangements in relation to aging and clinical conditions. (shrink)

The COVID-19 pandemic poses a health threat that has dominated media coverage. However, not much is known about individual media use to acquire knowledge about COVID-19. To address this open research question, this study investigated how the perceived threat is linked to media use and how media use is associated with perceived and actual knowledge about COVID-19. In a German online survey conducted between April 16 and April 27, 2020, N = 952 participants provided information on their perceived threat and (...) media use to inform themselves about COVID-19. In this process, they indicated how well they were informed about COVID-19 and subsequently completed a COVID-19 knowledge test. Results indicated that individuals who felt more threatened by COVID-19 used media more often to inform themselves but focused on fewer different media channels. Further, frequent media use was associated with higher perceived knowledge, but not with higher actual knowledge about COVID-19, reflecting an illusion of knowledge. Additionally, using fewer media channels was linked to higher perceived and actual knowledge. Finally, explorative analyses on the use of different media channels revealed that an illusion of knowledge emerged for using social media, public television, and newspapers. Potential explanations for the findings and implications for future research are discussed. (shrink)

Let T1 and T2 be two countable strongly minimal theories with the DMP whose common theory is the theory of vector spaces over a fixed finite field. We show that T1 ∪ T2 has a strongly minimal completion.

Obduktionen waren und sind ein Grundpfeiler der wissenschaftlichen Medizin, so dass von Befürwortern eindringlich eine ausreichend hohe Sektionsfrequenz gefordert wird. Dennoch bestehen vielfach Vorbehalte von Seiten der Patienten und der Angehörigen. In diesem Zusammenhang ergeben sich Konfliktfelder zwischen Aufklärung mit Zustimmung, Allgemeinwohl und Individualrechten. Der vorliegende Beitrag beschäftigt sich exemplarisch mit der Entwicklung der Sektionszahlen an der Universität Göttingen unter dem Wirken des Pathologen und Medizinethikers Georg Benno Gruber (1884-1977). Hierbei werden ethische, gesellschaftliche und politische Einflussfaktoren auf das Sektionswesen während (...) der Zeit der Weimarer Republik, des Nationalsozialismus und im Nachkriegsdeutschland dargestellt, analysiert und in ihrer moralischen Verwendung oder Instrumentalisierung bewertet. Besonderes Augenmerk soll der jeweiligen medizinethischen Fundierung gegeben werden, die Gruber vertrat. Vor diesem Hintergrund zeigt die historische und theoretische Studie wichtige Ansatzpunkte für die heutige medizinethische Diskussion um das Sektionswesen sowie Interessenkonflikte ethisch argumentierender Fachwissenschaftler.

We approach the virtual reality phenomenon by studying its relationship to set theory. This approach offers a characterization of virtual reality in set theoretic terms, and we investigate the case where this is done using the wellfoundedness property. Our hypothesis is that non-wellfounded sets (so-called hypersets) give rise to a different quality of virtual reality than do familiar wellfounded sets. To elaborate this hypothesis, we describe virtual reality through Sommerhoff’s categories of first- and second-order self-awareness; introduced as necessary conditions for (...) consciousness in terms of higher cognitive functions. We then propose a representation of first- and second-order self-awareness through sets, and assume that these sets, which we call events, originally form a collection of wellfounded sets. Strong virtual reality characterizes virtual reality environments which have the limited capacity to create only events associated with wellfounded sets. In contrast, the logically weaker and more general concept of weak virtual reality characterizes collections of virtual reality mediated events altogether forming an entirety larger than any collection of wellfounded sets. By giving reference to Aczel’s hyperset theory we indicate that this definition is not empty because hypersets encompass wellfounded sets already. Moreover, we argue that weak virtual reality could be realized in human history through continued progress in computer technology. Finally, within a more general framework, we use Baltag’s structural theory of sets (STS) to show that within this hyperset theory Sommerhoff’s first- and second-order self-awareness as well as both concepts of virtual reality admit a consistent mathematical representation. To illustrate our ideas, several examples and heuristic arguments are discussed. (shrink)

Our study explores the relationships between psychological and driving-related personality traits, fluid intelligence and cognitive abilities for drivers whose driving licence has been revoked due to intoxicated driving (alcohol and/or drugs). We were able to show that highly significant impacts on cognitive functions derive from the participants’ age and fluid intelligence. In addition, driving-related personality traits such as emotional instability, a sense of responsibility and self-control contributed significantly to some of the cognitive abilities that are important for fitness to drive. (...) Additionally, the mediating effects of fluid intelligence in the model are discussed. Traffic psychologists can use this knowledge in their assessment of drivers, mainly regarding the possible compensation of cognitive deficits regarding the fitness to drive. (shrink)

Problem: Visions of technology, future scenarios, guiding visions represent imaginations of future states of affairs that play a functional role in processes of technological research, development and innovation—e.g. as a means to create attention, communication, coordination, or for the strategic exertion of influence. Since a couple of years there is a growing attention for such imaginations of futures in politics, the economy, research and the civil society. This trend concerns technology assessment as an observer of these processes and a consultant (...) on the implications of technology and innovation. TA faces increasing demands to assess imaginations of futures that circulate in the present and to participate in shaping these through scenarios or foresights. More than ever, this raises the question, which propositions can be made based on these imaginations by TA and how this can be used in advisory practices. Imaginations of futures are relevant for TA not as predictions but in their significance and effectiveness in the present, which need to be understood and assessed.Contents: This discussion paper outlines how present significance and effects of imagined futures in technological research and innovation processes can be conceived and analyzed. In this paper, all forms of imaginations of technology futures will be called “socio-technical futures” because within them technological developments and social changes are interwoven and inseparably interrelated. In this paper, we discuss why TA should analyze socio-technical futures, how such analyses can grasp the societal conditions that are expressed in the imagined futures and how these become effective in processes of technology development, communication, decision making etc. We raise the question which self-reflexive positioning or possible realignment of TA is needed as a response to its increased concern with assessing and even co-producing socio-technical futures. The latter is often demanded regarding the growing attention by politics and publics to imaginations of futures with wide temporal and spatial reach.Addressee of this paper is the TA community in a broader sense. The aim is to sensitize colleagues for the topic and its challenges, to consolidate discussions and to provide theoretical and methodical suggestions for research in TA and related advisory practices with respect to socio-technical futures. This paper has been originally initiated during the workshop “The present of technological futures-theoretical and methodical challenges for Technology Assessment”, in which all of the paper’s authors participated. The contents of this discussion paper are preliminary results that shall initiate and guide further discussions. (shrink)

Throughout most of the 20th century Management Accounting was developed on the premise that it should help managers to decide how best to maximise the short-term financial profits of their businesses. In the emergent Corporate Social Responsibility (CSR) business environment Post, Preston and Sachs1 ask, ‘To whom and for what is the corporation responsible?’. In response to this question we examine publications describing recent changes in the corporate environment, and provide evidence of business decisions being made on the bases of: (...) environmental, societal and other criteria, besides those relating to financial profitability. We question whether such changes in the corporate environment are being reflected in the way that Management Accounting is being taught in business schools today. We provide details of a final year course that we have developed at our university. (shrink)

PurposeTo evaluate the prevalence and treatment patterns of speech and language disorders in Germany.MethodsA retrospective analysis of data collected from 32% of the German population, insured by the statutory German health insurance. We used The International Statistical Classification of Diseases and Related Health Problems, 10th revision, German Modification codes for stuttering, cluttering, and developmental disorders of speech and language to identify prevalent and newly diagnosed cases each year. Prescription and speech therapy reimbursement data were used to evaluate treatment patterns.ResultsIn 2017, (...) 27,977 patients of all ages were diagnosed with stuttering. Stuttering prevalence peaks at age 5 years. Cluttering was diagnosed in 1,800 patients of all ages. Developmental disorders of speech and language were identified in 555,774 AOK-insurants. Treatment data indicate a substantial proportion newly diagnosed stuttering individuals receive treatment, with slightly fewer than 20 sessions per year, on average. We confirmed a previous study showing increased rates of atopic disorders and neurological and psychiatric comorbidities in individuals with stuttering, cluttering, and developmental disorders of speech and language.ConclusionThis is the first nationwide study using health insurance data to analyze the prevalence and newly diagnosed cases of a speech and language disorder. Prevalence and gender ratio data were consistent with the international literature. The crude prevalence of developmental disorders of speech and language increased from 2015 to 2018, whereas the crude prevalence for stuttering remained stable. For cluttering, the numbers were too low to draw reliable conclusions. Proportional treatment allocation for stuttering peaked at 6 years of age, which is the school entrance year, and is later than the prevalence peak of stuttering. (shrink)

The paper starts from a phenomenology of violence that reconsiders the phenomenal contours of the seemingly opposed concepts of violence, on the one hand physical violence and on the other hand structural violence. We argue that the implied definiteness of their reciprocal separableness is not given. Instead, violence should be understood as the negation of sociality. As such, it is closely related to a basic form of trust in relation to people’s self-awareness, and their relation to others and to the (...) world. It operates as a background assumption that can only be grasped ex negativo. Shattered trust is induced by interpersonal violence. That is why we focus on traumatizing and traumatic experiences and its social implications. We argue that such an analysis is only rarely done within the discipline of sociology and we therefore suggest a systematic heuristic to study the social implications of traumata. Researching those implications in turn helps us to understand the phenomenon of violence and (basic) trust alike. (shrink)

Meeting 5G high bandwidth rates, ultra-low latencies, and high reliabilities requires of network infrastructures that automatically increase/decrease the resources based on their customers’ demand. An autonomous and dynamic management of a 5G network infrastructure represents a challenge, as any solution must account for the radio access network, data plane traffic, wavelength allocation, network slicing, and network functions’ orchestration. Furthermore, federation among administrative domains (ADs) must be considered in the network management. Given the increased dynamicity of 5G networks, artificial intelligence/machine learning (...) (AI/ML) solutions are strong candidates able to learn, and take quick provisioning decisions upon fast changes in network conditions. Therefore, this chapter presents an analysis of the state-of-the-art solutions for 5G networks’ management, where AI/ML solutions are discussed and compared with traditional methods. Additionally, the chapter provides a technology overview of both standards, and existing solutions regarding the 5G network management, and directions toward the integration of AI/ML in 5G networks.

The study investigates effects of the implementation of a law authorizing educational leave in Germany on individual participation in adult learning and education (ALE). In 2015, the federal state of Baden-Württemberg introduced the so-calledBildungszeitgesetz, legitimating an exemption for eligible employees of up to 5 days per year with continued payment of salary. Explaining participation in ALE is a central subject of educational research at national and international level. Current theoretical assumptions of rational choice and empirical findings of educational and socio-statistical (...) research suggest that within the general population, individuals’ availability of time affects the decision to participate and therefore lastly determines participation in ALE. However, current academia mainly discusses time as either a prerequisite for learning activities or as an observable outcome of participation and not as an explanatory factor. Furthermore, since recent studies remain on a descriptive level regarding influences of time on participation in ALE, no causal effects of the availability of time on participation are estimated. Hence, our study addresses this research gap by investigating effects of educational policy interventions such as theBildungszeitgesetzon participation in ALE. Policy interventions are ideally suited to examine the significance of time resources for participation, as the implementation of theBildungszeitgesetzprovides a specific timeframe for employees to participate in ALE outside of their working time. Drawing on data from the German National Educational Panel Study, we employ a difference-in-differences estimation strategy with propensity score matching and instrumental variable to identify the direct causal effect of the implementation of theBildungszeitgesetzon participation in ALE (N= 709). This combination toward causal inference controls for observed and unobserved baseline differences as well as heterogeneous treatment effects. The results reveal a non-significant but heterogeneous treatment effect of the implementation of theBildungszeitgesetzon individual participation in ALE. Contrary to our theoretical assumptions derived from rational choice approaches, we cannot confirm the hypothesis that the availability of time resources due to the implementation of theBildungszeitgesetzcauses a positive effect on participation in ALE. Furthermore, the results reveal that the implementation causes decreasing participation rates for younger adults, women and significantly for migrants. (shrink)

Research collaboration promises a useful approach to bridging the gap between research and practice and thus promoting evidence-informed education. This study examines whether information on research collaboration can influence the reception of research knowledge. We assume that the composition of experts from the field and scientists in a research team sends out signals that influence trust in as well as the relevance and applicability of the finding. In a survey experiment with practitioners from the field of adult education the influence (...) of different research team compositions around an identical finding is tested. The results show overall high trust, relevance and applicability ratings with regard to the finding, regardless of the composition of the research team. We discuss the potential importance of additional information about research collaborations for effective knowledge translation and point out the need for more empirical research. (shrink)

In contrast to vertical gene transfer from parent to offspring, horizontal (or lateral) gene transfer moves genetic information between different species. Bacteria and archaea often adapt through horizontal gene transfer. Recent analyses indicate that eukaryotic genomes, too, have acquired numerous genes via horizontal transfer from prokaryotes and other lineages. Based on this we raise the hypothesis that horizontally acquired genes may have contributed more to adaptive evolution of eukaryotes than previously assumed. Current candidate sets of horizontally acquired eukaryotic genes may (...) just be the tip of an iceberg. We have recently shown that adaptation of the thermoacidophilic red alga Galdieria sulphuraria to its hot, acid, toxic‐metal laden, volcanic environment was facilitated by the acquisition of numerous genes from extremophile bacteria and archaea. Other recently published examples of horizontal acquisitions involved in adaptation include ice‐binding proteins in marine algae, enzymes for carotenoid biosynthesis in aphids, and genes involved in fungal metabolism.Editor's suggested further reading in BioEssays Jumping the fine LINE between species: Horizontal transfer of transposable elements in animals catalyses genome evolution Abstract.
