Keywords: Corporation strategy; Market reaction to profit; Strategy of product differentiation; Strategy of expenditure leadership
Leadership strategic characteristics are margin expenditure of low sale with high sale mass, economic expense to criterion ration and main investments in factories and physical properties. While differentiation strategy is followed by high sale margin which is gained by goods quality and realized branding through investment in unobvious properties such as; investment in research part, development and advertisements, the strategic characteristics have twofold effects on investor reaction to published information about corporations. This research investigates the effect of corporation strategy on market reaction to profit in the accepted corporations of Tehran Stock Exchange (TSE). Research statistic population includes 856 accepted corporations in TSE from 2012 to 2016, while 142 corporations have been chosen by systematic deletion as the research statistic sample. The research is “application oriented” in term of its aim, its data are “quantitative”, the research performance time is “sectional”, its performance logic is “deductive”, and it performance method is “descriptive, measuring and casualty”. Paneling data method is used to analyze the research data based-on the research data kind. The findings indicate that corporation strategy has a positive meaningful effect on market reaction to earning, strategy of cost leadership has a positive meaningful effect on market reaction to profit, and differentiation strategy of product has a positive meaningful effect on market reaction to profit. These findings show that corporations that follow strategy of expenditure leadership their profit publications will be explained more generally and more changes will own in average believes of stock price. In the otherwise, profit announcements of corporations that follow strategy of differentiation will be explained by inhomogeneous and lower changes will own in average believes of stock price. The research helps knowledge level gradation about sectional changes of market reaction to profit announcement. Moreover, in this research price reaction convergence and transaction mass reaction to profit announcement have been indicated in the form of anticipation situation.

In current research has already done to investigate the effect of dimensions of Human capital on Marketing Capabilities in Private Banks. Often, human capital is described as intangible assets which can be applied as capital for competitive advantage. Thus, an organization which has strong marketing, has better performance in recognition of customer’ needs and comprehension of factors which influence on customer. This organization can position its trademark as for trademarks of its rivals which can discriminate and use high profitability. The aim of research is to discuss that does human capital influence on marketing capability? The statistical population consists of managers and experts of private banks of Kurdistan province and alpha Cronbach has been used to analyze data. In order to estimate reliability, Kolmogrov-Smirnov test has been used. On discussion the effects of human capital on marketing capability, three hypothesizes were confirmed at confidence level 95% and error 5%. This research confirms that attention to human capital in internal companies increases marketing capability and it is necessary managers and researchers to consider it.

The L-Band ATLAS GNSS service, a new land and maritime survey technique, is described and field check for accuracy in this study. The L-Band ATLAS GNSS system is a Global Based Augmentation System (GSBAS), developed by Hemisphere GNSS Technology, as a service to enhance real-time orbit and clock generation, dual redundant delivery of corrections from ground reference network via commercial communication satellites. Having significant development of mobile internet communication, GNSS receiver navigation software can utilizeL-Band ATLAS service for land survey and civil construction works. This work, GNSS dual frequency (L1/L2) single receiver is operated in L-Band ATLAS system by static and dynamic positioning measurement modes. This paper demonstrates a system test for L-Band ATLAS system in Thailand (Bangkok and Korat test sites) that monitors and assesses the accuracy of positioning measurement during March and April 2018. The accuracy assessments are based on both International GNSS Service (IGS) and local ground reference network of Department of Land (DOL) of Thailand. Real-Time L band positioning measurement outcomes are compared with Post-Processing results from IGS and DOL by using local map projection as Indian 1975 in different UTM zone 47N (Bangkok) and UTM zone 48N (Korat) in Thailand. The accuracy meets the requirement for GIS and Surveying being 4.1 centimeter in horizontal measurement and 32 cm in vertical measurement as comparing post-processing with IGS system and 17 cm in horizontal measurement in comparing with DOL Thailand system. This paper also discusses the system integration and development for improving GNSS accuracy by using currently available international and local Continuously Operating Reference Stations (CORS) services in Thailand.

Keywords: ANN; EMD; EEMD; IMFs; Hilbert–Huang transform (HHT); Kurtosis coefficient non-stationary vibrations; time-frequency
One of the methods for detection faults in structural and mechanical systems is processing vibrational signals extracted from the real system. The Hilbert–Huang transform (HHT) is a new and strong method for analyzing nonlinear and non-stationary vibrations based on time-frequency. This approach is based on decomposing a signal into empirical modes and Hilbert spectral analysis. In the current paper, first, vibrational signals of a roller bearing are decomposed into intrinsic mode functions (IMFs) using ensemble empirical mode decomposition (EEMD) method and IMFs sensitive to impulse are determined by Kurtosis coefficient. Then Kurtosis and standard deviation factors are extracted from the mentioned IMFs and used for training and validating the multi layers perceptron neural network. The results of network trial showed faulty or normal roller bearing and its fault type.

OMany problems of economic potential management in a regional industrial complex are closely associated with the establishment of the effective ways to maximize the use of all potential opportunities. The article suggests the priority directions to identify and mobilize the internal reserves of the regional industrial complex in the depressed republics of the North Caucasus Federal District. The negative state of the basic economic characteristics makes it necessary to conduct a complex of studies on a rational structure development concerning the national economy. These studies are becoming highly relevant with the actualization of globalization processes and the intensification of competition in world markets. This situation makes it necessary to optimize the sectoral composition of the Russian industrial complex. A thorough review of the basic provisions is also necessary in the framework of the implemented industrial policy at all levels. At the same time, it should also be noted that there is half a dozen of RF regions against the background of globalization, which play a significant role in the country economy. All this suggests the need for deep economic research on the development of a regional industrial policy, based on the analysis of regional industrial complex competitiveness level.

Keywords: Strategic gap; Confidence-seeking discourse; Mixed exploratory approach; Least squre; Strauss and Corbin's paradigm model.
Management researchers have long been concerned about the fact that management research has not been widely successful in affecting the management practices. Hambrick argues that the management research mainly aims at decision making and management practices; however, the translation of academic knowledge to measures adopted by managers has practically failed. The present study sought to develop an evidence-based decision-making model in insurance companies. The present study was fundamental and applied in terms of its objective and mixed exploratory research with regard to its nature. In the qualitative part of this study, twenty directors of insurance companies and policy-making experts were selected through purposeful and snowball sampling. Moreover, one hundred seventy directors of active insurance companies participated in the quantitative part to test the model. Structural equation approach and data-based theory was used to analyze the data. Finally, an evidence-based strategic decision-making model was developed according to Strauss and Corbin's paradigm model. Further, the relationships among the research variables were examined using the partial least squares method and the validity of the relationships was confirmed.

Keywords: economic crisis; mountain regions; depressed republics; rural territories; multifunctional development; ecological settlements; sustainable development.
Modern socio-ecological-economic processes of the rural territory functioning in the depressed republics of the North Caucasus make it necessary to rethink the rural community problems and develop new approaches, mechanisms and directions for their recovery and sustainable development. The rural settlements of the mountainous areas in the republics of the North Caucasus Federal District could not fit into market relations and lose their socio-economic purpose catastrophically in the sphere of agrarian relation organization and implementation, which threatens with unpredictable consequences not only for the socio-economic, but also for the political sphere. In these conditions, the strategic task for the future is to conduct structural and functional transformations of rural areas, to develop new qualities and characteristics, which allow to adapt to changing external socio-economic conditions.
