What do the TOSCA guilt and shame scales really measure: Affect or action?
No full textPsychologists have long used the Test of Self-Conscious Affect (TOSCA) as an instrument for empirically distinguishing between trait emotions of guilt and shame. Recent assessments of the internal structure of the TOSCA guilt scale suggest that it may not measure the experience of guilt, but rather motivation to make amends for personal wrongdoing. In contrast, TOSCA shame may better assess the tendency to experience negative self-conscious affect. Previous research did not take into account that TOSCA guilt theoretically should only predict emotions in a situation of wrongdoing; we put this idea to the test in two studies. Experimental, but not control, participants received believable feedback that they had shown involuntary prejudice towards a member of a minority group. In both studies TOSCA guilt predicted reparative action after feedback was given, including expressing non-prejudiced views and recommending financial compensation to the minority group. However, TOSCA guilt had no relationship with feelings of guilt or shame after expressing prejudice. In contrast, TOSCA shame was a better predictor of feelings of guilt, shame and other self-critical emotions, but did not predict compensatory action. These findings suggest motivation rather than emotion as a mechanism behind past findings involving TOSCA guilt
TOSCA neutron spectrometer: The final configuration
No full textThe forward and backward scattering parts (phase 11) of the new neutron spectrometer, TOSCA, replacing the old TFXA and TOSCA (phase 1), have been successfully installed at the ISIS pulsed neutron source. The results show a significant enhancement in the counting rate due to the larger detector area. The improved resolution (to 1.5%-3% of the energy transfer) as compared with the previous instruments (TXFA: 2.5%-3.5%; TOSCA-I: 2%-3.5%) has been achieved by increasing the primary flight path from 12 m to 17 m. A chopper has been added in order to avoid neutron frame overlap and to reduce the fast neutron background. Additional diffraction capability will be installed in the near future. An example of the high resolution that is routinely available is provided by the spectrum of potassium hydrogen phtalate at 20 K
Neutronic developments on TOSCA and VESPA: Progress to date
No full textWe report recent developments regarding the TOSCA (ISIS, UK) and VESPA (ESS, Sweden) neutron broadband chemical spectrometers, both joint ventures between CNR (IT) and ISIS (UK). TOSCA has seen the first major upgrade since it first became operational over fifteen years ago. The new design of the primary spectrometer, which exploits a state-of-the-art, high-m neutron guide and associated chopper system, is boosting the useful neutron flux by over an order of magnitude. Feasibility studies for an upgrade of the secondary spectrometer have been performed, outlining an additional order-of-magnitude gain in performance. In the case of VESPA, the novel characteristics and challenges arising from a long-pulse spallation source such as ESS are part of the drivers of the instrument design. For both the primary and secondary spectrometers, a detailed analysis of expected performance, supported by both simulations and analytical models, is being carried out, also capitalizing from experience on TOSCA. Indeed, for instrument design and optimization, extensive neutron-transport simulations and baseline studies of neutronic response have become a must, along with extensive benchmarking against much-needed experimental data. All these combined efforts represent the first opportunity to benchmark a broadband, high-resolution chemical spectrometer in terms of measured vs. simulated response
TOSCA: a world class inelastic neutron spectrometer
No full textPresent applications are reaching the limitations of the inelastic neutron scattering spectrometer, TFXA at ISIS. The new instrument TOSCA, currently under construction, builds on the strengths of TFXA (a wide energy range, good resolution and ease of operation!, but will have detector banks in forward and backward directions to give a much larger detector area. A longer primary flight path of 17 m will result in a significant improvement in resolution. The open geometry in forward scattering allows a larger range of momentum transfers to be accessed. TOSCA will have a diffraction capability with detectors at a range of angles to provide a good coverage of Q-space and d-plane spacing
TOSCA Lightning: An Integrated Toolchain for Transforming TOSCA Light into Production-Ready Deployment Technologies
No full textThe OASIS standard TOSCA provides a portable means for specifying multi-service applications and automating their deployment. Despite TOSCA is widely used in research, it is currently not supported by the production-ready deployment technologies daily used by practitioners, hence resulting in a gap between the state-of-the-art in research and the state-of-practice in industry. To help bridging this gap, we identified TOSCA Light, a subset of TOSCA enabling the transformation of compliant deployment models to the vast majority of deployment technology-specific models used by practitioners nowadays. In this paper, we demonstrate TOSCA Lightning by two contributions. We (i) present an integrated toolchain for specifying multi-service applications with TOSCA Light and transforming them into different production-ready deployment technologies. Additionally, we (ii) demonstrate the toolchain’s effectiveness based on a third-party application and Kubernetes
The TOSCA incoherent inelastic neutron spectrometer: progress and results
No full textThe back-scattering part (phase I) of the new incoherent inelastic neutron spectrometer, TOSCA, replacing the old TFXA, has been successfully installed at the ISIS pulsed neutron spallation source. The results, owing to the much larger detector area. show a significant enhancement of the counting rate and an improvement of the resolution. In spring 2000, the forward scattering bank (phase II) will be completed and, during the final installation, the whole instrument will be moved; from the present 12 m primary flight path to 17 m. This will result in a large improvement of the overall resolution (fram 2-3% to 1-1.5% of the energy transfer). A chopper will be added in order to avoid neutron frame overlap and to reduce the fast neutron background. In addition, TOSCA will have a diffraction capability
