Towards a stakeholder model for the co-production of the public-sector information system by Zita P. Correia

“…</b> The implications of the systemic approach to PSI, are: a) a holistic and open view of the entities and elements involved; b) clarification of the role of each of the stakeholder groups; c) commitment of each group to the public sector information system, and hence co-responsibility for the system. The principle of co-production is applied to the PSI system, by building on lessons from development studies. …”

Solving of Two-Dimensional Unsteady-State Heat-Transfer Inverse Problem Using Finite Difference Method and Model Prediction Control Method by Shoubin Wang, Rui Ni

“…The paper adopts Finite Difference Method (FDM) and Model Predictive Control Method (MPCM) to study the inverse problem in the third-type boundary heat-transfer coefficient involved in the two-dimensional unsteady heat conduction system. The residual principle is introduced to estimate the optimized regularization parameter in the model prediction control method, thereby obtaining a more precise inversion result. …”

Impacts of Thermal Inertia Factor on Adiabatic Decomposition of 40% Mass Content DCP in Ethyl Benzene by Xiaojuan Wu, Liping Chen, Guoning Rao, Wanghua Chen, Ruili Yin

“…DSC experiment showed that ethyl benzene has no effect on the characteristic parameters of thermal decomposition of DCP, such as the temperature of the exothermic peak (Tpeak) and the decomposition energy (Ea), and the thermal decomposition reaction of 40% DCP followed the one-step reaction principle. ARC experiment showed that with the increase of inertia factor (Φ), the measured initial decomposition temperature (Ton) would be higher and the caculated Ea and pre-exponential factor (A) would be greater. …”

From the Criminalization of Substances to the “War on Drugs” Policy: A Century of Prohibitionism in Brazil by José Guilherme Magalhães e Silva, Luís Felipe Zilli, Letícia Godinho de Souza

“…A systematic analysis of national and international legislation reveals that the prohibitionist enterprise was successful in Brazil due to two factors: i) as an ideational set, it was integrated into structuring discursive fields of Brazilian political culture, dialoguing with the stigmatization of marginalized populations and criminalization of their practices; and ii) as an ordering principle of public policy, it has demonstrated remarkable resilience and adaptability, incorporating elements of alternative models into its framework without compromising its fundamental structures. …”
