Although liability under general tort and contract law principles is not limited to a certain amount, liability arising under a carriage contract is limited by the majority of international transport conventions and national legislatures and, there are certain reasons given to justify the “essential departure from the current rules of civil law” and it is common for the liability of the carrier to be limited under the international regimes regarding transportation. The limitation of liability, which is nowadays considered to be a basic right rather than a privilege, is not a matter of justice, but merely a matter of public policy. Naturally, under modern transport law regimes, willful misconduct is not the only situation whereby the carrier or ship-owner loses his right to limit. Conventions regarding means of transportation, particularly road carriage, also employ provisions for breaking the limits. The aim of this paper is to investigate the effects of willful misconduct and gross negligence of road carrier in CMR, CVR, and COTIF 1999 (CIM and CIV) conventions and for this purpose admitted solutions in said convention is discussed.

Identity crisis in today's architecture has become the concern of the scholars due to its compliance with modernity, inattention to humans' differences and variety in conditions and contexts for creating architecture works as well as its emphasis on the constant preset patterns. In such circumstances, "Iranian-Islamic architecture pattern" has been introduced by several scholars as a solution for reviving the historical and religious identity to architecture and complying it with the related fields. In this regard, the identification of key factors influencing the components of this pattern can affect the definition of this issue. Therefore, this article tries to introduce the components of Islamic-Iranian architecture and determine the consistency of these components with educational content of architecture (particularly, at B.A level). This study has employed a qualitative approach, determined the components of Islamic-Iranian architecture and the consistency of the content of architecture with that components through the simulation research method. The findings show that in the current program of architectural education, the share of training the Islamic principles, personal and social values and contexts is very low compared to the share of training the architecture tools. On the other hand, architectural education has mostly emphasized teaching the architectural tools rather than the fundamentals, which prevents the architecture students to form a holistic insight into the issue.

Today country success in economic, social, political , cultural and tendencies are the hostages and pawns of coherent and dynamic didactic system and approved; The education and didactic programs for qualification improvement and dynamism need to evaluate and scrutiny quantitatively and qualitatively. Current study started with the goal of presenting faculty competency evaluation for the reason of qualitative improvement of Islamic Azad University. Research in term of how to collect and compilation the data is descriptive- survey and in term of goal and target type is practical that by doing general scrutiny in literature and subject history and past, we drawled the theoretical frame and conceptual model in this study. Nominee educational members opinions (faculty members (self- assessment), supervisors (superiors), students (clients) of Fars stat Islamic Azad different universities, are the research society. In this research with researcher evaluation in 24 active units in Fars state, approximately 125000 persons examined. That sample volume selected by the clustered random sampling method (kerjesi and Morgan formula), 380 persons, for the reason of collecting dates we used a researcher questionnaire that its validity confirmed by the specialists and its stability calculated by using the Kronbakh’s Alfa method 0.84.Researche questionnaire includes effective component in competency in five general axis, collects the data. Then with using 360 degree evaluation method, executed. For the data analysis me used descriptive statistic method and elicitation statistic (fact oral analysis, vilkakson and Friedman) that the results of the study as follows: 1.drawing the model of competency evaluation of faculty (main dimension of evaluation indexes of faculty competency’s).2.in the field of evaluation of current situation from the dimensions and competence skill parameters, ethical values, role, personal, favorable status exists. But in the performance and functional dimension and its subcomponents unfavorable status and lower than average level evaluated and the results of ranking of evaluation of dimensions of competency’s of faculty in order the most priority is related to skill dimension and the least priority is related functional and performance dimension.

No unique method has been so far specified for determining the number of neurons in hidden layers of Multi-Layer Perceptron (MLP) neural networks used for prediction. The present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. The data used in the present research for prediction are consumption data of water subscribers in Fasa City of Fars Province (Iran) between the years 2010 to 2013. Ultimately, using the respective data set, the data of the subsequent year 2014 can be predicted. In the present research it was observed that the mean square errors of per data (MSEPD) for the abovementioned algorithms are less than 0.2, indicating a high performance in the neural networks’ prediction. Correlation coefficients using genetic and hill climbing algorithms were respectively equal to 0.891 and 0.759. Thus, GA was able to leave a better effect on optimization of neural network.

Earnings management has inverted the main objective of financial reporting through the distortion of the actual economic performance of companies and prevented the complete transfer of information to market. Given the importance of subject of research, incentives that cause earnings management have been reviewed from various aspects. The main purpose of this research is to examine the relationship between competition in industry and pricing power at product market and earnings management in the companies listed in Tehran stock exchange. For this, modified Lerner index was used to measure pricing power and three middle Lerner indices including industry, reverse number of firms in the industry, four-firm concentration ratio were used as the indices of competition in industry. To measure earnings management, Modified Jones Model was used. The statistical population consists of all the firms listed in Tehran stock exchange. With regard to the considered criteria, 100 companies among 9 industries were selected as sample based on two digit ISIC codes. Findings of research indicate that the companies which enjoy the pricing power at product market less likely manage their earnings. Another finding indicates that earnings management increases by increasing competition in industry. Hence, the investors who intend to invest in competition industry should pay more attention to earnings management.
