Abstract: 

Curriculum as the backbone of the educational system is one of the important factors in creating fundamental changes in the higher education system; The purpose of this research is to explain the effectiveness of entrepreneurship education Model from the Islamic point of view and  the Leader, so that it can be used to examine the curriculum of architecture education in terms of the realization of entrepreneurship components in students. The method of the current research is a mixed exploratory one, which in the qualitative part, by examining the views of the Leader in his articles, books and speeches, descriptive propositions of his thought regarding the effectiveness of entrepreneurship education were extracted with the implication research method. In the quantitative part, the data was analyzed using structural equation method and using SPSS20 and smart PLS software. The findings showed that the Model of entrepreneurship from the Leader'spoint of view can be divided into four main pillars: vision, knowledge, skill and business. And each of these main pillars overlaps with the Model of effectiveness of entrepreneurship education in architecture curriculum. In this way, architecture higher education centers can, in addition to creating entrepreneurship curricula in the field of architecture, by identifying the potentials in the curricula of this field, strengthen the strengths and eliminate the weaknesses in them. This Model, while providing the conditions for the realization of entrepreneurship education in academic fields, provides the context for the implementation of a local Model in the light of Islamic orders.

Abstract: 

To calculate shielding failure of a lightning protection system, several analytical methods such as Electro-Geometric Model and Rolling Sphere Method have been proposed. These methods are used to determine protected and unprotected areas, but they can’t show the frequency of shielding failure to determine more risky areas. In this paper, a new numerical Model is proposed by using Leader Progression Model and Artificial Bee Colony Algorithm to identify the most vulnerable area on complex structures. The Progression of lightning downward Leader, the inception and propagation of upward Leaders are considered step by step until final jump. Structures, air terminals, downward and upward Leaders are Modeled by different shapes of charges, and the electric field in an environment is computed by charge simulation method. Lightning is assumed as artificial bee, and areas with high shielding failure are the best food sources with high nectar amount. So the result produced by ABC algorithm is the most lightning risky area. Finally, lightning performance of an asymmetric structure protection system is evaluated, and based on simulation results the best position of air terminals is determined. The proposed method can be used for protection system design of any complex structure.

Abstract: 

Direct lightning strokes to launch pad damage some vital instruments. Thus, the lightning protection system is used to protect instruments. Calculating the probability of direct lightning strokes is the main consideration in lightning protection system design, however this calculation is not simple since the shape of launch pad is complex. In this paper, a 3-D numerical analysis Model based on Leader Progression Model (LPM) is proposed to calculate the probability of direct lightning strokes to launch pads. The Progression of lightning downward Leader, the inception and propagation of upward Leaders are Modeled step by step until final jump. Launch pad, lightning protection system, downward and upward Leaders are Modeled by different shapes of charges, and the environment electric field is computed using charge simulation method. Then, lightning performance of two actual launch pads are evaluated, and the simulation results are compared. Finally, the high voltage laboratory tests have been achived to validate the proposed protection system design.

Abstract: 

The term "Scientific Leadership" (SL) was first coined by the Supreme Leader during a meeting with Imam Sadegh students on Eid Ghadir in 2005. The aim of this study is to present a systematic Model of "Scientific Leadership" based on the viewpoints of the Supreme Leader, based on a qualitative approach and the use of the Thematic Analysis Method, well suited for recognizing the patterns of data. For this purpose, the content related to SL was extracted from each Supreme Leader's statements about SL. Then through the three stages of the research methodology, 40 main themes in four dimensions of SL including scientific, managerial, cultural, and political dimensions, and five functions of SL including agenda-setting, policy formulation, policy adoption, policy implementation, and policy evaluation, were categorized. After identifying three types of components including concepts (topics and main keywords), dimensions, and functions related to SL, the three-level Model of SL was achieved. The results show that the scientific, cultural, and management dimensions are respectively the most emphasized by the Leadership, and "Policy formulation" is at the top of the functions. Also, "Policy adoption" is the least important function. In the final part, the comparison of research findings with previous similar research and the most important policy suggestions of the research are presented.

Abstract: 

Views, organizational loyalty, membership, humanitarianism, faithfulness, significance and performance feedback, all are vastly related to the moral Leader. But, no one has studied how these 7 features are related to the characteristics of the Leader-follower mutual relations. The aim of this paper is to discuss these relations and to develop a Model for describing them. This research is practical and applied in terms of the aim and descriptive-correlative due to its nature. The data are collected by using questionnaires and statistical population selected from the teachers of Islamic Azad University, Boroujerd Branch. The authors used Pierson method, Regression and Confirmative Factor Analysis to evaluate the hypothesis. The findings represented that the relation-oriented behaviors of a manager or Leader play a fully main role in making a connection between a moral Leader and LMX. However, the other features such as views and organizational loyalty are less important. This paper is the first applied research that tries to study the intricate relations of 7 features of the moral Leader and reciprocal relations of Leader-follower. By using the term "Applied", the authors concluded that the morality of the Leader and Leader-follower mutual relations are two necessities in selecting the Leader and promotion programs.

Abstract: 

The purpose of this article is to present a Model of economic balance in order to achieve economic justice in Islamic society. This research explores the general framework of the Supreme Leader of the Revolution's view on economic balance by inverse index method, then by developing this view, by The method of inferring the theory of Islamic economics, it derives the Model of economic balance with a seven structure. Leadership is at the center of gravity and the top of this Model's pyramid. The intellectual core, the government, the people, the family, the market and the charity make up other components of the Model. Faith and piety are the foundation of the Model structure. The components of the Model play a role in directing the society towards balance depending on the degree of faith and piety. The higher the degree of faith and piety in the components, the faster and more accurate the movement towards balance and the more balanced society will be.
