Economic environmental valuation remains a much debated and contested issue. Concerns have been voiced that it is unable to capture the manifold immaterial values of ecosystems due to conceptual and methodological issues. Thus, additional value categories (social values) as well as novel valuation approaches like deliberative (monetary) valuation are areas of growing interest, yet the theoretical foundations are rather weak. Against this background, this article aims to develop a consistent conceptual framework for making sense of social values in economic environmental (...) valuation. Based on a holistic view of society and individuals, the role of institutions, the social environment, culture and transcendental values is emphasised. To synthesise diverging concepts of value into an economic concept and to account for the multidimensionality of social values, the framework consists of three spheres: social, natural and contextual. The novel framework demonstrates that social values may be integrated into a preference-based utility framework when denoting a holistic understanding of social preferences and human embeddedness in nature and society.

Mechanisms for QoS provisioning in communication networks range from flow-based resource reservation schemes, providing QoS guarantees, through QoS differentiation based on reservation aggregation techniques to adaptation of applications, compensating for incomplete reservations. Scalable, aggregation-based reservations can also be combined with adaptations for a more flexible and robust overall QoS provisioning. Adaptation is particularly important in wireless networks, where reservations schemes are more difficult to realize. It is widely accepted that usability of Cellular or Mobile IP can be largely improved if (...) adaptation is incorporated. Adaptation, in turn, depends on coding techniques involved and on user requirements. Those impose certain preferences and ordering relations on QoS hierarchies or degradation paths to be followed along when adaptation is performed. With the advent of MPEG4 coding techniques, more sophisticated adaptation schemes are more likely to be supported in the future. (shrink)

This is not the style an academic should adopt who wants to get a tenured position today. It even took the University of Königsberg fifteen years after Kant had earned his doctoral degree before they appointed him to a chair in philosophy. For those among us who feel already somewhat beyond the time bracket which allows for competition and efficiency, it may be consoling to know that Kant published his Critique of Pure Reason, the Copernican work in philosophy which molded (...) the thought of all centuries to come, at the age of 57. The famous little work which shall provide us with the focal text for this lecture, Kant’s essay On Eternal Peace, appeared in 1795 when he was 71. (shrink)

Contrary to the prevailing opinion the servum in Calpurnius Flaccus’ fourth declamation (ed. Håkanson 4,12) is to be kept very well, whereas the emendations sacrum and tectum are unnecessary and not very convincing.

Der private, sehr gefahrdete Bucherbestand Friedrich Nietzsches gilt als ein besonders interessantes Beispiel einer Schriftstellerbibliothek des 19. Jahrhunderts.

Unilateral spatial neglect is a disorder characterized by the failure to report, respond to, or orient toward the contralateral side of space to a brain lesion. Current assessment methods often fail to discover milder forms, cannot differentiate between unilateral spatial neglect subtypes and lack ecological validity. There is also a need for treatment methods that target subtypes. Immersive virtual reality systems in combination with eye-tracking have the potential to overcome these shortcomings, by providing more naturalistic environments and tasks, with sensitive (...) and detailed measures. This systematic review examines the state of the art of research on these technologies as applied in the assessment and treatment of USN. As we found no studies that combined immersive VR and ET, we reviewed these approaches individually. The review of VR included seven articles, the ET review twelve. The reviews revealed promising results. All included studies found significant group-level differences for several USN measures. In addition, several studies found asymmetric behavior in VR and ET tasks for patients who did not show signs of USN in conventional tests. Particularly promising features were multitasking in complex VR environments and detailed eye-movement analysis. No VR and only a few ET studies attempted to differentiate USN subtypes, although the technologies appeared appropriate. One ET study grouped USN participants using individual heatmaps, and another differentiated between subtypes on drawing tasks. Regarding ecological validity, although no studies tested the prognostic validity of their assessment methods, VR and ET studies utilized naturalistic tasks and stimuli reflecting everyday situations. Technological characteristics, such as the field of view and refresh rate of the head-mounted displays, could be improved, though, to improve ecological validity. We found no studies that utilized VR or ET technologies for USN treatment up until the search date of the 26th of February 2020. In conclusion, VR-ET-based systems show great potential for USN assessment. VR-ET holds great promise for treatment, for example, by monitoring behavior and adapting and tailoring to the individual person’s needs and abilities. Future research should consider developing methods for individual subtypes and differential diagnostics to inform individual treatment programs. (shrink)
