Abstract:

In bankruptcy prediction, the proportion of events is very low, which is often oversampled to eliminate this bias. In this paper, we study the influence of the event rate on discrimination abilities of bankruptcy prediction models. First the statistical association and significance of public records and firmographics indicators with the bankruptcy were explored. Then the event rate was oversampled from 0.12% to 10%, 20%, 30%, 40%, and 50%, respectively. Seven models were developed, including Logistic Regression, Decision Tree, Random Forest, Gradient Boosting, Support Vector Machine, Bayesian Network, and Neural Network. Under different event rates, models were comprehensively evaluated and compared based on Kolmogorov-Smirnov Statistic, accuracy,F1 score, Type I error, Type II error, and ROC curve on the hold-out dataset with their best probability cut-offs. Results show that Bayesian Network is the most

insensitive to the event rate, while Support Vector Machine is the most sensitive.

 Acceptance of E-procurement in Organisations: Using Structural Equation Modeling (SEM) Muhammed S. Maddi1, Paul Davis2 and John Geraghty3, 1Dublin City University, Ireland & College of economic and Management Bani Walid City University, Libya and 2Dublin City University Business School, Ireland 3Dublin City University Mechanical and Manufacturing Engineering School, Ireland Abstract This research is concerned with the development of a realistic model for e-procurement adoption by organizations and groups observing the Rules of Islamic Sharia (RIS). This model is intended to be based on the behavioural control, subjective norms, and the recognition of the benefits and risks of eprocurement adoption. The developed model, “E-Procurement Adoption Model” (E-PAM), combined and extended two existing models previously used for information technology adoption. Central to the design of the E-PAM is the principle that a realistic model should consider all relevant psychological, social, ...

 Hybrid Encryption Algorithms for Medical Data Storage Security in Cloud Database Author Name Fenghua Zhang，Yaming Chen，Weiming Meng and Qingtao Wu, Henan University of Science and Technology, China Abstract Cloud database are derivatives of Cloud computing. At present, most medical institutions store data in cloud database. Although the cloud database improves the efficiency of use, it also poses a huge impact and challenge to the secure storage of data. The article proposes a hybrid algorithm to solve the data security problem in the hospital cloud database. First, the AES algorithm is improved. The improved algorithm is called P-AES algorithm. The P-AES algorithm is then combined with the RSA algorithm, called a hybrid algorithm. The experimental results show that the hybrid encryption algorithm has the advantages of fast encryption and decryption speed, high security, good processing ability for longer data, and can solve the data security problem in cloud database to a certain...
