Social Intelligence and Language Proficiency: Are They Related?
Ebrahim Khodadady and Ima Mansori Namaghi
This study explored the relationship between social intelligence and English language proficiency by employing Reading the Mind in the Eyes Test (RMET) developed by Baron-Cohen et al. (2001) and cloze multiple choice item test (CMCIT) designed by Hale et al. (1988) as their representative measures, respectively. The administration of the two tests to 181 undergraduate university students of English Language and Literature and Theology and correlating the scores obtained on the two tests showed that social intelligence is significantly related to language proficiency. When the participants were, however, classified into low, middle and high proficiency groups on the basis of their z-scores on the CMCIT and the social intelligence of these three groups were compared with each other, the mean score of middle and high proficiency groups did not show any significant difference on the RMET and were thus collapsed into one, i.e., middle-high group. The correlational analysis of the scores obtained by low and middle-high proficiency groups on the RMET and CMCIT showed that there is only a significant relationship between the social intelligence and language proficiency of middle-high group. The results are discussed and suggestions are made for future research.

Discrete Shearlet Transform Based Texture Classification Using Block Based Energies
M. Kanchana and P. Varalakshmi
In this paper, an efficient approach for the classification of texture images based on Discrete Shearlet Transform (DST) is proposed. The classification of texture is achieved by extracting block based energy from the shearlet decomposed image. First, the texture image is decomposed by DST at various decomposition levels with multi-directions. Then the proposed block based energy is extracted from each sub-band of the decomposed image. The block size used in the proposed system varies from 4 to 64. These block based energies are used as features to classify the given texture image using robust nearest neighbor classifier. Brodatz database texture images are used to evaluate the proposed method. The performance is compared with state of art techniques involving wavelet transform, gabor transform and statistical features. The results show that the proposed shearlet transform based classification provides better classification accuracy.

Yakut-Binte-Sadek, Mohammad Shahriar, Waheeda Nasreen, Mahboob Hossain and Mohiuddin Ahmed Bhuiyan
In the present study antimicrobial resistance pattern of 32 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) to 17 antimicrobial drugs was done from which 7 multidrug resistant isolates were selected. Amongst the 32 isolates of Staphylococcus aureus 21(66%) were found resistant to amoxicillin, 19(59%) to cloxacillin, 18(56%) to oxacillin, 32(100%) to penicillin G and most surprisingly 15(53%) to vancomycin. They showed maximum (91%) sensitivity to both gentamicin and imipenem, 84% to tetracycline and 81% to ciprofloxacin; moderate sensitivity to neomycin (78%) and rifampicin (75%); low sensitivity to ceftriaxone and chloramphenicol (66%) and erythromycin (53%). Sensitivity showed less than 50% to cephalexin, cephradin, cotrimixazole and methicillin group antibiotics. In this study 1% SDS with acridine orange was used to isolate plasmids from the clinical isolates. Isolates showing resistance to an antimicrobial drug became sensitive to the same antimicrobial when grown in luria broth in presence of 1% SDS and 1% SDS plus acridine orange. The change in sensitivity pattern was to ceftriaxone, cephalexin, cephradine, cotrimoxazole, gentamicin, neomycin, and tetracycline. After gel electrophoresis, plasmid profiles of the isolates showed that those isolates grown in presence of 1% SDS and 1% SDS plus acridine orange were more prominent than those without SDS treatment.

Granular Computing, A Topological Approach for Decision Making
Ad El-Monem M. Kozae and S. A. Saleh
Granular computing can be described as a process that occurs on two steps which are granulation and computation. On the other hand topological structures and its generalizations are constructed using granules, and topological basic concepts are tools for using types of granules to compute quantitive measurements from granules which are, in almost cases,qualtitive concepts. Thus supra topologies as generalized topological structures can be viewed as general mathematical models for qualitative and quantative real life problems.Also,topological facts and concepts are important tools for discovering rules that help in decision making and taking. The concept of supra topological granulation is introduced and studied. This structure is based on granules associated with general binary relation resulted from the available information on the collection of objects in information systems. Approximations based on this type of granulations are given, examples and counterexamples are presented. Also ,we give comparisons between suggested approximations and Yao approximations. Applications example with real valued data is given to indicate the suggested supra granulation method.

A. Karthikeyan, Akanksha Mohan Gupte, Suryalok Sarkar, T. Shankar and Sivacharanreddy.V
PSO (Particle Swarm Optimization) is an efficient cluster based heuristic technique which has proved its competence for solving optimization problems in various fields. PSO can be further extended by implementing Dual Cluster heads in the basis of same algorithm. This dual cluster head strategy is capable of achieving load balancing and extending the re- election cycle of cluster head selection in large Wireless Sensor Network (WSN) thereby resulting in balanced energy consumption throughout the network and extending the network longevity significantly. The main objective of designing any WSN is to achieve energy optimization and enhanced network lifetime. In this paper, is presented a simple but a very effective way to further enhance the performance of the Dual Cluster Head clustering technique using PSO (D-PSO) without increasing much computational complexity in order to achieve considerable improvement in network lifetime.

Shahla Saffarzadeh and Gholamreza Jandaghi
Existence of balance between competitive strategy and supply chain strategy is a company's obligations in the current competitive world, it is proportional to gain and maintain competitive advantage. On the other hand, there are very close ties between structure and strategy. Given the importance of the concept of strategy, and the necessity of considering this important issue in manufacturing industries, the aim of this study is to examine the relationship between competitive and supply chain strategy along with consideration of the role of the organizational structure as a variable affecting this appropriateness in Yazd province food industries of Iran. While, it is considered the impact of structure on performance too. Accordingly, the study is addressed based on Chase model of competitive strategy dimensions, Ballou model of supply chain strategy dimensions, Higginson and Alam model on performance criteria. Moreover, complexity, formalization and centralization are considered as the dimensions of structure. Samples of the study are executives of Yazd food companies and inferential statistics, structural equation modeling, is used to analyze data. Data analysis shows significant causal relationship between competitive strategy and supply chain strategy and performance is changed according to the type of competitive strategy. The results also indicate that the performance does not change depending on supply chain strategy. The role of organizational structure as a moderator of the relationship between competitive and supply chain strategy and its impact on performance is also confirmed.

K.L. Jeyaraj, C. Muralidharan, T. Senthilvelan and S.G. Deshmukh
The response surface methodology (RSM) is helpful in developing a suitable approximation for the true functional relationship between the independent variables and the response variable that may characterize the nature of the process. In this experimental design, four factors were studied. The experiments were conducted according to the layout of rotatable central composite design of 24 factorial design, preferably with 6 center points and 6 axial points. Five response functions values are obtained. Empirical relationships were developed to predict the responses of color fast finish on Article no: 1846 (20s cotton × 20s cotton 108 × 56 3/1 Drill) and shade: Royal blue at the 95 percent confidence level, incorporating color fast finish process parameters. From the estimates of anova, normal probability plots and t-test the significance of all the factors effects, quadratic effects and interaction effects are ensured. Then a feed-forward three-layered back propagation neural network was used with numerical optimization technique namely scaled conjugate gradient learning algorithm. The ANN architecture used for this work is 4-131-1, with 4 corresponding to the input values, 13 to the number neurons in the hidden layer and 1 to the output. The predictive regression model is found to be capable of better predictions of responses of color fast finish. The perfectly designed central composite design is more suitable for the regression analysis in this case than artificial neural network. Also our color fast finish response models are well obliged for the quadratic models. So the regression provides better results in this case.

Muhammad Tariq Khan, Sheraz Ahmed, Naseer Ahmed Khan and Sarfraz Tanvir
Marketing mix is the most fundamental concept of marketing defined as: a set of controllable marketing tools that a company uses to create a desired response in the targeted market. Set of these tools or the elements of marketing mix are the basic, tactical components of a marketing plan. So ‘Marketing Mix’ were also referred and known as the Four P's i.e. product, price, place of distribution, and promotion. But the number of these Ps have increased gradually from 4 to 5, then 6, then 7, then 8 and lastly to 15. This paper, which is based on the extraction from studies of many researchers, tells the story of growth of Ps from 4 to 15.
