Methodology Investigation. Software Maturity Model Validation. Phase 2

This study develops a method to measure the performance level of reverse logistics implementation operated by companies engaged in the construction machinery remanufacturing industry. A framework of reverse logistics performance measurement that focuses on the processes and resources is developed using the Capability Maturity Model approach. The framework was designed in three dimensions: front-end, engine, and back-end, with five levels of model maturity, i.e., initial, aware, defined, managed, and optimizing. The assessment was carried out through 25 indicators and model validation was done by implementing the proposed framework on three construction machinery remanufacturing companies in Indonesia. The results show that the three companies were at different maturity levels. Further analysis explains that the front-end dimension has the lowest score of a successful reverse logistics implementation. Therefore, companies that engage in a similar field should focus more on the front-end dimension to improve their overall reverse logistics performance.

Evidence Collection

The process of establishing credibility in computational model predictions via verification and validation (V&V) encompasses a wide range of activities. Those activities are focused on collecting evidence that the model is adequate for the intended application and that the errors and uncertainties are quantified. In this work, we use the predictive capability maturity model (PCMM) as an organizing framework for evidence collection activities and summarizing our credibility assessment. We discuss our approaches to sensitivity analysis, model calibration, model validation, and uncertainty quantification and how they support our assessments in the solution verification, model validation, and uncertainty quantification elements of the PCMM. For completeness, we also include some limited assessment discussion for the remaining PCMM elements. Because the computational cost of performing V&V and the ensuing predictive calculations is substantial, we include discussion of our approach to addressing computational resource considerations, primarily through the use of response surface surrogates and multiple mesh fidelities.

Dissonance Reduction

After having been told they were free to accept or refuse, pupils aged 6–7 and 10–11 (tested individually) were led to agree to taste a soup that looked disgusting (phase 1: initial counter-motivational obligation). Before tasting the soup, they had to state what they thought about it. A week later, they were asked whether they wanted to try out some new needles that had supposedly been invented to make vaccinations less painful. Agreement or refusal to try was noted, along with the size of the needle chosen in case of agreement (phase 2: act generalization). The main findings included (1) a strong dissonance reduction effect in phase 1, especially for the younger children (rationalization), (2) a generalization effect in phase 2 (foot-in-the-door effect), and (3) a facilitatory effect on generalization of internal causal explanations about the initial agreement. The results are discussed in relation to the distinction between rationalization and internalization.

Alzheimer Demenz

Die Blockade von Serotoninrezeptoren, insbesondere des Serotonin-Rezeptortyps 5-HT6, als Zusatztherapie in Kombination mit Cholinesterasehemmer, hat in experimentellen Versuchen sowie in einer Phase-2-Studie positive Effekte bei Demenz gezeigt. Im Rahmen eines Phase-3 Entwicklungsprogramms wurde nun die Effektivität des selektiven Serotoninrezeptor-Antagonisten Idalopirdin bei leichter bis mittelschwerer Alzheimer Demenz geprüft.
