Abstract
This paper is based on an interpretive ethnography conducted in a public organization ("Edareh"). This paper attempts to achieve some part of the ethnography’s goal to describe how "ideal worker" is socially constructed by the different organization’s stakeholders (managers and employees), so as to stay and to be “advantaged". This goes through the light of analyzing the two key events, that is to say "management changes" and "layoff". At first, drawing on Schneider and Ingram framework, the characteristics of “ideal worker” construct from new managers’ view, their sense making of the employees with this framework and trying to move into the full realization of the construct is expressed. Then, based on social construction efforts on the part of employees, their struggles to stay, to not being fired, and even to get promoted - intended to changing and modifying the new manager’s “ideal worker” construct - is described in the form of a manifesto for staying in “Edareh”.

Abstract
This study aims to investigate and analyze the realization of grounding in the form of foregrounding and back grounding in Persian-children’s narratives according to linguistic devices of aspect (perfective/imperfective) and voice of verb (active/passive) and also the effect of age on using these devices.
To investigate how foregrounding and back grounding are accomplished in Persian-speaking children’s narratives by linguistic devices of aspect (perfective/imperfective) and voice of verb (active/passive) two Hickmann’s (2004) pictorial stories were used. Three groups of school monolingual Persian-speaking children of age 7, 9, 11 and a control group of adults, at age 30 (each group consisting of 10 female subjects) took part in this study. The subjects were tested individually. They were asked to narrate two pictorial stories for one of the researchers. All the narratives (80 narratives, from two pictorial stories) were recorded by a voice recorder. Then, they were transcribed, described and analyzed by SPSS software.
Results showed that the use of perfective and imperfective aspects had a meaningful relationship in the three groups of children, that is, the use of perfect aspect in foreground decreased while that of imperfect aspect increased with an increase in the age. On the contrary, in adult group, the use of perfect aspect in foreground increased but that of imperfect aspect decreased. The same relationship was observed in background. Moreover, the use of active voice of verb was more dominant than that of passive voice of verb in the narratives. No meaningful relationship was observed between the use of passive voice of verb in foreground and background on one hand, and the participants’ age, on the other hand. Based on the results of Chi-square test, there was a significant relationship between perfective and imperfective aspects in foreground and also in background and the age of the narrators (p < 0.05). However, there was no significant relationship between the use of passive voice of verb in foreground and background and the age of the narrators (p < 0.05). Thus, the first two null hypotheses of the study were rejected, and the third one was accepted.

Abstract
The main purpose of this study is to predict the behavior of employees according to perception of possible changes in their organizational resources. This research aims to discover the latent behavioral intentions which individuals showing in common, within an organizational ecosystem through an objective approach. Using sequential exploration strategy, the research was implemented through 5 main steps and research model has been verified by means of experimental and empirical methods. The ecosystem studied in this study, was Iranian state and semi-state banks, which were precisely studied in 416 subjects. Also, in order to obtain a model for predicting the organizational behavior of employees, at first, behavioral intentions were typologized by conservation of resources approach, and then modeled with fixed and random effects in form of mixed equations. Results showed that predictions of human behaviors at the ecological level of resources have great commonalities that can be identified by a resource-based approach. The results also showed that the behavioral intentions of employees in Iranian state and semi-state banks in threatenedsocial support is to be passive, andin the presence of positive or negative perceptual interaction from leader, this tendency could change from " being passive” to "trying to retain" in both cases. Identifying the boundary points of changing behavioral intentions and the distance of employees’“behavioral intention" from these points was another finding of this study that could be a guide for regulating effective interventions of leadersin the studied ecosystem.

Abstract
It’s well known that today’s organizationsens counter the national, regional and international dynamic and complex changes.The survival and development of all organizations require to provide some new methods, alternatives, innovations (new products and services)processes and so on.
Since Corporate entrepreneurship involves promoting the entrepreneurial behaviors in an organization, therefore, the organizations have to consider the "corporate entrepreneurship" as a critical success factor.
In this paper, the authors atlempted to recognize the corporate entrepreneurship obstacles. Thus, organizational culture, supervision and control, attention to short & long term profits and the ways of giving rewards were studied. The obtained results based on the statistical analysis showed that the conservative organization al culture, close supervision and control, attention to short term profits, and giving unappropriate rewards are the fundamental obstacles of corporate entrepreneurship.

Abstract
The aim of this study is to investigate the effect of the addressee’s power and gender on the choice of the type and number of encouragement strategies employed by Persian male and female university students based on Brown and Levinson’s (1987) theory. A number of 60 M.A. students (30 males and 30 females) from the University of Sistan and Baluchestan participated in this study. Discourse completion test and role play technique were utilized as two data gathering instruments. The data were analyzed using the Chi-square and Independent-T test (p<.05). The results indicated there was a significant relationship between the addressee’s power and the type as well as the number of encouragement strategies employed by male and female university students. The most frequent strategy type was the “negative politeness” giving deference for the addressee with higher power (the professor). As to the number of strategies, the most and less frequent ones were the combination of two and nine strategies, respectively. The addressee’s gender had an effect on the type of the strategies used by male students in three situations; while it didn’t have any effect on the number of strategies used by male students and also on the type and number of strategies employed by female students. The most frequent strategy type used by female students was the “positive politeness” and the combination of three strategies for male and female addressees; by male students: “positive politeness” for male addressees and “negative politeness” and the combination of two strategies for female addressees.
1. Introduction
Interpersonal interactions and how they are formed play a significant role in human social life. One way to interact is through using different speech acts. Many factors can involve in making use of politeness principle in interacting and communicating. In life and social interactions, human beings use various speech acts such as request, agreement, disagreement, swearing, giving advice and encouragement in order to express their meaning. One of the most important and effective theories in pragmatics field is Austin’s speech act theory. He believes that every sentence may have a performative feature and also it has an action within it; therefore, every sentence should be considered within its context (Austin, 1962). Employing the speech acts depends on various factors such as language characteristics and socio-cultural frameworks. Among these factors, politeness is one of the crucial factors in interpersonal communications in different societies and cultures. Politeness can be represented in various aspects of behavior based on the factors such as the addressee’s social status, power, and gender in using speech acts. One of the most widely used speech acts among their various range in interpersonal interactions is the encouragement speech act. If this speech act is appropriately used in the right context, it will have important effects on relations between individuals as well as on saving face based on power and gender of the addressee. Thus based on what is mentioned and according to the importance and impact of the encouragement speech act in every person’s social life, the type and number of encouragement strategies and the effect of the addressee’s power and gender on the use of this speech act by Persian language male and female university students can be investigated and analyzed based on Brown and Levinson’s (1987) politeness theory. The research data were gathered via two data collection tools including discourse completion test (DCT) and role-play technique. The hypotheses of the present study are as follows:
1. Due to the addressee’s power, there is a significant difference in the useage of the type of encouragement speech act strategies among Persian-speaking male and female university students.
2. Due to the addressee’s power, there is a significant difference in the usage of the number of encouragement speech act strategies among Persian-speaking male and female university students
3. Due to the addressee’s gender, there is a significant difference in the usage of the type of encouragement speech act strategies among Persian-speaking male and female university students.
4. Due to the addressee’s gender, there is a significant difference in the usage of the number of encouragement speech act strategies among Persian-speaking male and female university students.
2. Literature Review
By considering linguistic, cultural, and social characteristics of language, different speech acts have been examined by many researchers. Rahimpour and Yaghubi Noutash (1999) investigated the impact of gender and subject on speech act in English language learners. Amou Ali Akbari Najafabadi (2007) has conducted a research to examine the Social-interpersonal power and politeness strategies in Persian. Pishgadam and Rasouli (2011) examined the persuasion speech act strategies among Iranian language learners by considering speaker’s gender. Zeynali Dastuyee (2012) studied the effect of addressee’s power and gender on the type and number of apology and refusal strategies employed by Sarawani university students. Shafaghi (2013) investigated the promise speech act and the use of promise in political discourse. Pishghadam and Attaran (2015) studied the speech act of argumentation in English and Persian advertisements. Azarparand (2019) has investigated changes in addressing strategies based on Brown and Levinson's Politeness theory. This case study research has been conducted in Tehran University among Iranian lecturers and students.
3. Methodology
In the present study, the effect of the gender and power of addressee variables on the choice of politeness strategies in encouragement speech act in Persian language is investigated. This study is a descriptive-analytical research. A number of 60 M.A. students (30 males and 30 females) from the University of Sistan and Baluchestan participated in this study. Their age was ranged from 23 to 34 years old. They had an average age of 25 years. All subjects were randomly selected, were monolingual, and Persian-speaking postgraduate students who were studying in different fields of study. Discourse completion test (DCT) and role play technique were utilized as two data gathering devices. The questionnaire which was used in the study was a researcher-made one. The data were analyzed using Chi-square test, Analysis of variance (ANOVA), and Independent T-test.
4. Results
The present study examined the encouragement speech act based on two determining variables including the power and the gender of the addressee in different contexts. The findings of the study show that the addressee’s power can be an important and effective factor in the selection of the type and number of the encouragement strategies. The most frequent strategy type is the “negative politeness” strategy. In addition, the addressee’s power has an effect on the number of the encouragement strategies employed by male and female university students. As the power of the addressee increases, the use of more complex strategies becomes more and simple strategies are utilized in dealing with the addressee with low power. As to the number of the strategies, the most frequent and less frequent ones are the combination of two and nine strategies respectively. The results also indicate that the gender of the addressee affects the type of the encouragement strategies used by male university students while, it doesn’t affect the number of strategies used by male students. It also doesn’t have any effect on the type and number of the strategies used by female university students. Also, data analysis reveals that there is no significant relationship between the addressee’s gender and the number of the encouragement strategies. In other words, the addressee’s gender has no effect on the number of the encouragement strategies used by male and female university students

Abstract
Cold spray is a process which is used in coating industry and manufacturing of new parts. Experimental studies of this process are expensive and also very difficult due to high velocity of particles. Therefore, one effective method to study this process is its computer simulation. Previous works show that the Johnson-Cook hardening law has been usually used for simulation of this process. However, it is unanimously believed that this model is not able to reproduce the material behavior at extremely high strain rates commonly occurred in the cold spray process. Therefore, the simulation results are expected to improve if a suitable material model for extremely high strain rates is used. In this study, the PTW1 model was implemented in ABAQUS commercial finite element package. The cold spray process was then simulated for copper using both the PTW and Johnson-Cook hardening models. A comparison between the simulation and experimental results showed that the PTW model did improve the simulation results. The predicted flow stress by Johnson-Cook model was also shown to be not so sensitive to strain rate at extremely high strain rates.

Abstract
Box-columns are suitable members for structures with moment frames in two directions but performing the internal continuity plate in them causes some practical troubles. Details of the new proposal to alleviate this problem in box-columns is CONXL connection. This connection includes a set of Collar Flange Top (CFT), Collar Flange Bottom (CFB), Collar Corner Top (CCT), Collar Corner Bottom (CCB) and when the depth of the beams is more than 460 mm, Collar Corner Middle (CCM), Collar Web Extension (CWX) (only in the face of beam to column connection) and also a set of diagonal pre-tensioned high strength bolts (45 degrees angle), which collectively make up CONXL node. The bolts and collars performance make up a rigid diaphragm around the column. All collar flanges top and bottom are connected to the beam by means of groove welding with complete joint penetration, and the connection of collar web extension to the beams and that of collars corner to the column walls is made by fillet weld; collar corners are connected to each other through groove weld in factory and the pieces are just assembled in worksite. The objectives of presenting these details are industrializing, removing weld in workplace, removing continuity plate, enhancing quality, speeding up the construction, and simplifying the inspection. Through the distribution of force among collar systems, forces are transmitted from beams to the columns. The aim of this study is to numerically study the seismic behavior of CONXL connection without filler concrete of columns and to reduce the number of collar bolts with different arrangements. In order to reach this purpose, the numerical results of specimens; RBS and Kaiser bolted bracket (KBB) connection are compared to experimental results to verify the modeling and analyzing and good agreement is observed between numerical and experimental data. Afterward nine specimens of CONXL moment connections in box-columns not filled with concrete whit axial force in single, planer and bi-axial loading conditions with different arrangement of bolts are studied and their performances are evaluated. Results showed that seismic behavior of specimens with beam section depths equal or less than W30 series under cyclic loading, even with reducing the number of bolts to 16 numbers, is suitable in the over 0.04 radian rotations. Also, use of 16 numbers of bolts in connections with W30 series of beams, when it would be appropriate that use for corner connections (Single sided loading), and the specifications of ASTM-A36 for beams material to be used. Also, whatever the position of bolts to be outer than in collar flanges, axial strain in the bolts shank is bigger and its slip is less. The optimal position of the bolts is near the middle of the collar flanges. The results also showed that seismic behavior of all specimens with columns without concrete filling is appropriate and the column will remain without any remarkable local buckling in over 0.04 radian inter-story drift angle.

Abstract
Cracks due to manufacturing processes or in-service applications can propagate and cause failure in structures. Therefore, it is of interest to find a suitable fracture assessment method for predicting crack initiation. Main approaches for fracture assessment of structures are global approach and local approach. In the global approach, it is assumed resistance against fracture can be measured by a critical values of a far from crack tip parameter like K or J. In this study, Beremin model of local approach is used for predicting brittle fracture which studies stress and strain fields at the crack tip. The model introduces unknown parameters which have to be calibrated using experimental fracture data. The purpose of this study is evaluating of conventional calibration methods of local approach parameters using the experimental brittle fracture data of three point bending specimens, determining limitations, and finally presenting a new calibration method to produce suitable parameters for predicting brittle fracture of the specimens by using local approach to fracture. This study shows that conventional calibration method using experimental fracture data of three point bending specimens has limitation in some cases. Also, by introducing location parameter of Weibull distribution as a stress triaxiality criteria in Beremin model, a new rational method for predicting brittle fracture of the three point bending specimens with different constraints is presented.

Abstract
There are too many different reasons for organizational project failures. Non-supportive management, internal resistance, and situational changes can be mentioned as some of the most important reasons. In formation sciences (IS) projects follow the same rules. Because of their considerable effect on the quality and quantity of organizational output, this article tries to propose some solutions to minimize the probability of such failures in Iranian organizations. Informatics Services Corporation (ISC) as the largest e-banking company in Iran has been chosen as the case of study. Vensim software (Version 9) was applied to simulate the real situation available in ISC. By testing different solutions, it was conducted that the most effective ones are: continuous training, establishing sustainable management systems via process clarification and procedure deployment, helping to ameliorate contactors' financial condition, and clear written contractual relations instead of verbal agreements in all phases of the projects. The major advantage of this article is its concentration on project gap.

Abstract
Regarding hemodialysis patients’ limitations in consuming different foods, providing them with a product with health-promoting effects is important. The objective of this study was to develop a functional food from whey protein for this disease condition and assess its sensory, chemical, and nutritional characteristics. Fermented and unfermented beverages were prepared as a mixture of whey protein concentrate (8.5%), permeate (1.4 % for fermented), mint flavor (0.01%), vitamin E (0.18%), and water. Ty17A starter was used for the fermented blend. After pasteurization, and homogenization, the blends were stored until the sensory, chemical, and nutritional evaluations were done. Data were analyzed by SPSS Software (version 16). The pH values of the fermented and unfermented beverages were 3.8 and 6.02, respectively. The medians of all sensory attributes were greater than 4 for the fermented and less than 3 for the unfermented beverages (except color). All sensory attributes other than the color were significantly different between beverages (P< 0.05). The overall acceptability of the unfermented beverage was less. No significant nutritional differences were seen between beverages. Some of the nutrients values in the beverages are desirable for hemodialysis patients (Protein: 7.9-8 g 100 g-1, Fat: 0.4%, Trans fatty acids: 2%, Saturated fatty acids: 56.15% Phosphorus: 9.25-9.35 mg 100 g-1, Potassium: 0.0295 %, Sodium: 62.5 mg 100 g-1, and vitamin E: 400 mg 220 mL-1). The microbial counts of both were safe. Vitamin E fortified fermented whey beverage might be a good recommendation for hemodialysis patients because of its protein quality, low fat, phosphorus, sodium, and potassium and high vitamin E contents.

Abstract
Recently, the design and production of biodegradable films have received special attention than synthetic packaging due to the reduction of environmental pollution. The aim of this study was to investigate the effect of Persian gums (1%) and gellan gum (1%) on the physical, mechanical and morphological properties of composite films based on sodium caseinate (10%) as film reinforcing agents. The films were synthesized by solvent evaporation and the effect of each gum on the characteristics of the composite films was evaluated. The results showed that the addition of gums strengthened the composite films. So that the composite films showed mechanical resistance and good barrier properties versus moisture and light. The surface properties and morphology of the films also showed that the gums were well computability to the casein film and formed uniform and stiff films. In addition, composite films had acceptable transparency. Thus, it can be concluded that the use of composite films and the combination of different polysaccharides with protein matrices can improve the properties of the resulting films. On the other hand, by adding antimicrobial and antioxidant agents to biodegradable films, they can be considered as active packaging.

Abstract
Interaction of companies with customers in the form of customer relationship management has changed significantly. Identifying characteristics of different customers and allocating resources to them according to their value to the firm has become one of the main concerns in customer relationship management. The purpose of this paper is to provide an appropriate model for customer segmentation based on some of the most important financial and demographics characteristics influencing factors of customer lifetime value (CLV). The process proposed in this study was performed in Saman insurance company. After determining RFM model indices, which include date, frequency and monetary of purchase, AHP method used for weighting them among 180000 customers. The optimal number of clusters based on the silhouette and impact of RFM indicators was done by using Two-step algorithm and then customers classified through K-Means clustering algorithm. Results provided a platform to analyze the characteristics of customers in three main sections. Also, by prioritizing clusters based on the RFM indices, valuable customers were identified. Finally, some suggestions were presented to the company to improve its customer relationship management system.
