Voluntary turnover has direct and indirect expenses for organizations and for this purpose; it has one of the richest literatures in academic works. Due to the especial role of knowledge workers in organizations, these expenses in knowledge-based organizations are more important and more costly than that of other organizations. One of the latest theories in the field of voluntarily turnover was introduced by Lee and Mitchell (1994) that was named “Unfolding Model of Turnover” to describe the process of decision of voluntary turnover. This theory is distinguished from its similar theories from two main aspects: First, they introduced new elements like shock. Second, they introduced... 

Globalization and high rate development in all categories of scientific fields have become a very substantial motive to make effort in R&D affairs all over the world. Therefore, the high volume of investment in this area and Also the importance and urgency of R&D according to economical development statistics and its mutual and close relation with it specially in context of Iran, it is necessary to establish an effective tool to recognize gaps and bugs of subsystems working in the area using high volume investment so as to improve the position of each section of the total body of industry in this regard.

 

In the modern world of software engineering, software evaluation has earned a special position. The presence of consultation companies in evaluating the software will confirm this specialty. Web technology, as a new trend in computer science, has attracted the attention of many researchers and practitioners. As known nowadays, most of the software solutions are Web-based. Such software is technically called Web application. The methods of evaluating Web application include the use of traditional metrics in software engineering. The intelligence of the Web in computer science has been the core of much research.
This study is intended to use intelligence, as one of the new features of the... 

Monumental structures are cultural and aesthetic bases in every nation, and our duty to maintaining these valuable remnants is obvious clearly. Meanwhile, the vaults have essential role as main elements in the Islamic architecture, and evaluation of their performance as well as retrofitting with regard to placing in earthquake-prone regions has high importance. Therefore, in this dissertation, performance of spherical and pointed domes are evaluated. Hence, 13 traditional Iranian domes are modeled with linear and non-linear material behavior in ABAQUS finite element software to verifying effect of their geometries in seismic performance. Base on Complex behavior of these models, they... 

Textbooks play major roles in education and incorporation of textbooks into the courses can better the outcome of the learning (McGrath, 2006; Sheldon, 1988). Considering the role of textbooks, it seems crucial to examine and evaluate textbooks to select the best material for the educational courses (Tomlinson, 2001). This study focused on the evaluation of the EFL textbook, Prospect 1, which is currently taught at secondary schools of Iran. The researcher intended to evaluate the textbook from the perspectives of both teachers and learners based on the evaluation model proposed by Litz (2005). The participants of the study were 173 learners and 102 teachers who filled out the questionnaires... 

According to Sheldon (1988) textbooks are visible hearts of any English language teaching program. Relevant textbooks are prerequisites of an appropriate teaching and learning situation (Hutchinson & Torres, 1994). Evaluation is helpful for making subsequent informed decisions through providing information on the usefulness and effectiveness of textbooks (Allwright, 1981). The Right Path to English and English Book are two Iranian textbook series that have been prescribed by the Ministry of Education for teaching in public Junior and Senior high schools, respectively. Employing Litz's (2005) questionnaires, attitudes of Iranian learners and teachers were obtained on both the series.... 

Today in many industrial sectors, technology has made significant progress. Investing in advanced manufacturing technologies, especially computer integrated manufacturing systems is essential in order to survive in a competitive environment, improve performance, response to demand fluctuations and increase customer satisfaction. With available technologies and systems in computer integrated manufacturing (CIM) and its related technologies, the application of CIM in manufacturing enterprises is a reality and can meet the need of complicated manufacturing environment. Implementation of these systems brings many tangible and intangible benefits. But, according to several factors that must be... 

The current study aimed at both analyzing and evaluating Prospect course books(2012) with reference to a list of criteria which mainly consisted of: layout and physical appearance, different language skills, vocabulary, grammar, content and supplementary materials. Also a comparison was carried out between Prospect textbooks and Hip Hip hooray 2nd edition (2004) – a globally published ELT textbook taught at many Iranian private language institutes, in the related parts. The study is a qualitative one and makes use of descriptions and comparisons for providing data then content analysis has been used. The results showed that there are some positive points regarding Prospect, including... 

This research investigates the role and effects of knowledge management processes in reducing both cost and waste at the Dorsa Leather Goods Company. This methodology is based on both qualitative and quantitative research methods. The qualitative stage consists of analysis of past research and interviews with all levels of management. This stage leads to identifying knowledge management factors, effective in reducing cost and waste. Subsequently, we identified five main aspects encompassing all the effective aforementioned factors. These aspects are strategic, organizational structure, human resource, organizational culture, and technological infrastructure.The quantitative stage is... 

Automatic Speech Recognition (ASR) systems are a significant part of Personal Assistants in mobile phones. But because of the time-dependent nature of ASR systems, they are computation and memory-intensive tasks. On the other hand, mobile devices utilize a Low-Power design to extend battery life and improve user experience, making them incompatible with heavy-loaded tasks such as ASR systems. For instance, if we run an inference with a 60 seconds audio file on a well-known open-sourced Speech Recognition System named DeepSpeech, it will only take 49 seconds for a desktop PC to generate the results. Still, a mobile phone with ARM64 architecture with the same input file will take 92 seconds to...
