Purpose This work proposes the ISMRM Raw Data (ISMRMRD) format as a common MR raw data format, which promotes algorithm and data sharing. Methods A file format consisting of a flexible header and tagged frames of k-space data was designed. Application Programming Interfaces were implemented in C/C++, MATLAB, and Python. Converters for Bruker, General Electric, Philips, and Siemens proprietary file formats were implemented in C++. Raw data were collected using MRI scanners from four vendors, converted to ISMRMRD format, and reconstructed using software implemented in three programming languages (C++, MATLAB, Python). Results Images were obtained by reconstructing the raw data from all vendors. The source code, raw data, and images comprising this work are shared online, serving as an example of an image reconstruction project following a paradigm of reproducible research. Conclusion The proposed raw data format solves a practical problem for the MRI community. It may serve as a foundation for reproducible research and collaborations. The ISMRMRD format is a completely open and community-driven format, and the scientific community is invited (including commercial vendors) to participate either as users or developers.

This paper investigates the phenomenon of judicial corruption and incorporates it into Polinsky, A. M. (1980). Strict liability vs. negligence in a market setting. American Economic Review, 70, 363–367 framework so as to analyze the efficiency of the negligence rule. By shedding light on the role of social norms in regard to the phenomenon of judicial corruption, this analysis provides implications for policy. First, more prevalent corruption at the status quo tends to intensify the extent of the corruption itself and, as a result, the effectiveness of the government’s corruption enforcement is greatly lessened. This implies that an excessively lenient policy of corruption may result in an uncontrollable consequence; once corruption becomes rampant, it is costly to bring it down. Of great importance, in the presence of such a corruption effect, the social optimum cannot be achieved based on the negligence rule and the equivalence between the strict liability and negligence rule fails. Secondly, the attitude of the society toward a corrupt judge plays a crucial role in governing the effectiveness of an efficient wage arrangement. If the society can fully accept a corrupt judge, corruption will never be controlled even with the incentive wage scheme.

Recent observations suggest that as performance-related pay has been increasingly used, (i) compensation has grown with labour productivity, and (ii) there has been a rise in income inequality. This study is a theoretical attempt to provide a convincing explanation of these observations. We develop an endogenous growth framework comprising a profit/revenue-sharing scheme that simultaneously governs income inequality and economic growth. Therefore, we show that a share-based scheme can cause the workers to engage in performance pay seeking and, as a result, boost economic growth. Nonetheless, the intensive use of performance pay also results in higher income inequality. Because of the increased use of performance pay, there exists a positive relationship between economic growth and income inequality. While this result contradicts the traditional notion, it is supported by recent empirical studies. Our welfare analysis indicates that a more intensive sharing scheme does not necessarily raise the level of social welfare, even though it is favourable to economic growth. *We are grateful to two anonymous referees for helpful comments and suggestions.
