This paper investigates the mechanism through which short selling of a bank’s stocks can trigger the failure of the bank. In the model, creditors, who learn information from stock prices, will grow increasingly unsure about the bank’s true fundamentals in facing noisier stock prices; thus a run on the bank is more likely because of creditors’ concave payo¤. Understanding this, speculators condu...

the investigation of dimensional efficiency for branches of maskan bank in resources collection and facilities allocation: approach of super efficiency model with weight restrictions. the scarcity of financial resources of banks, especially in developing countries like as iran, leads to planning for improving efficiency and productivity. improving efficiency needs to performance measurement and...

While many researchers devoted numerous articles to the organizational culture, relatively few articles have been contributed to culture and performance research. The purpose of this study is to shed light on the role of organizational culture on performance. To achieve this goal and in order to measure organizational culture, Denison organizational culture model was used. The components of thi...

design of a logistics network in proper way provides a proper platform for efficient and effective supply chain management. this paper studies a multi-period, multi echelon and multi-product integrated forward-reverse logistics network under uncertainty. first, an efficient complex mixed-integer linear programming (milp) model by considering some real-world assumptions is developed for the inte...

improving time series forecastingaccuracy is an important yet often difficult task.both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. in this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...

This paper presents photonic devices with 3 dB/cm waveguide loss fabricated in an existing commercial electronic 45 nm SOI-CMOS foundry process. By utilizing existing front-end fabrication processes the photonic devices are monolithically integrated with electronics in the same physical device layer as transistors achieving 4 ps logic stage delay, without degradation in transistor performance. ...

the frequent occurrence of currency crises in recent years brought the early warning literature back in the researchers spotlight. in recent years, concept of an early warning system (ews) developed that should be able to identify various costly events, such as currency crises, early enough for policy makers to reduce the costs. this study attempted by using iran's economy quarterly data d...
