Economic Theory and the Financial Crisis
Procedia - Social and Behavioral Sciences, 2012 I want to probe in the role of the market in allocating resources in this very preliminary essay. One does not have to see study deeply to that the failure of markets for various kinds of derivative securities to perform properly is an essential element of the current financial crisis. Actually, financial crises are not a new phenomenon. The history of

Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Finding predictors of corruption from European firm level survey data: a random forest approach
Journal of Business Economics and ManagementCorruption remains a significant constraint for firms in Europe, despite ongoing institutional reforms. The main goal of this paper is to obtain a list of firm-level variables that can serve as predictors of corruption perception using a machine ...

Economic Review, 2011 This paper aims to show the evolution of the role and importance of education in economic theory, especially in theoretical approaches to economic development after World War II. In order to find answers and to present a current issue why and how certain countries have made progress while others have regressed in the development process, many theories ...

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers
Advanced Materials, EarlyView.Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
