Shahzad Ahmad Khan, Yan Liang, Sumaira Shahzad
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.49051
Abstract: Adoption of E-Commerce and Electronic Supply Chain Management (E-SCM) by small and medium enterprises (SMEs) has developed a tremendous performance in business process. SMEs in Pakistan are trying to enhance their competences by adopting a new technology to enter into the global market. The survey was aimed to investigate the current status and future direction of the adoption and benefits of E-Commerce and E-SCM by small and medium enterprises in Pakistan. A mailed questionnaire survey was conducted to collect data from 210 SMEs as samples located in Karachi, Gujranwala and Faisalabad, Pakistan. The results suggest that E-Commerce and E-SCM adoption has a significant, positive influence on SMEs, who have significantly higher average sales growth rate, on-time order management and delivery process than non-adopters. The findings of this study can be useful for SMEs in general as a means of understanding how E-Commerce and E-SCM adoption positively affects the firm’s performance.
An Empirical Study of Perceived Factors Affecting Customer Satisfaction to Re-Purchase Intention in Online Stores in China  [PDF]
Shahzad Ahmad Khan, Yan Liang, Sumaira Shahzad
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.83032
Abstract: Online stores (e-stores) are growing in China. Consumers perceive some factors affecting their satisfaction to re-purchase intention in e-stores. This study investigates the perceived factors affecting customer satisfaction to re-purchase intention in e-stores. The satisfaction toward the online stores channel environment depends on the customer’s perception and also online consumer experiences (OCEs) of the active online shopping stores. From a questionnaire survey, 302 usable data are obtained and hypotheses are tested using multiple regression analysis. The analysis suggests that seven constructs—price, convenience, product information, return policy, financial risk, product risk and delivery risk—are significant with customer satisfaction to re-purchase in e-stores. This study emphasizes that the importance of customer satisfaction provides more benefits and less risk to re-purchase in e-stores. The finding of this study will help e-store’s managers/ owners to understand customer’s perceptions in online shopping stores and their satisfaction.
Quality Enhancement of Corporate Management Systems: An Overview of Best Management Practices  [PDF]
Giron Kamonja, Yan Liang, Muhammad Tayyab Sohail, Shahzad Ahmad Khan
Journal of Service Science and Management (JSSM) , 2014, DOI: 10.4236/jssm.2014.74027
Abstract:

In this my present study, I elaborate different types of management, management staffs, types of managers and leaders along with their capacities of work and their roles in any organization or institute to achieve the desired goal with the help of employees. A study found that most of the CEOs of the 62 major US-based companies spent at least 10 percent of their time in quality enhancement efforts. The critical importance of employees’ involvement in the quality process of an organization is based on the belief that the best process innovation ideas come from the people actually doing the job. Employee involvement in quality efforts can only come about when the employees know that the organization cares for them. Best companies do not just confine education and training to their shop floor employees and managers. Top executives are actively involved in the learning process themselves. Training is the key element of management system. For the smooth run of any organization we always need proper training for all employees including leadership authority.

Quality Improvement in Management System: A Case Study of CCTEC Company China  [PDF]
Giron Kamonja, Yan Liang, Muhammad Tayyab Sohail, Shahzad Ahmad Khan
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.44028
Abstract:

Certain difficulties are inherent in the implementation of the improvement of the quality of service, particularly in the Design Management Department. There is often a difference on the issue of translating vision between senior management and Design Department for service improvement into effective, operational QI programs. Middle managers have a key role to play, but often they are overlooked which leads to undermining their efforts to improve the quality programs offered by senior management. This paper describes the first phase of a PhD research project to determine and develop the role of middle management in successful implementation of quality management programs. A framework for quality improvement implementation, including key issues of importance to middle managers regarding their proactive involvement in QI, is suggested. Finally, the initial implementation of the model in a company is discussed.

Methyl 2-(4-acetamidobenzenesulfonamido)benzoate
Islam Ullah Khan,Shahzad Sharif,Salamat Ali,Waqar Ahmad
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811009500
Abstract: The molecule of the title compound, C16H16N2O5S, has the shape of the letter V but with a small twist; the dihedral angle formed between the benzene rings is 79.66 (9)°. The presence of an intramolecular N—H...O hydrogen bond, leading to an S(6) ring, correlates with the near coplanarity of the carboxylate ester group with the benzene ring to which it is connected. The acetamide residue is slightly twisted out of the plane of its benzene ring [C—C—N—C = 13.1 (3)°]. In the crystal, supramolecular chains along the a axis are mediated by N—H...O hydrogen bonds. These are connected into layers via C—H...O interactions.
catena-Poly[bis(propane-1,3-diaminium) [[aqua(sulfato-κO)bis(sulfato-κ2O,O′)cerate(IV)]-μ-sulfato-κ3O,O′:O′′] dihydrate]
Ali Farooq Meer,Saeed Ahmad,Shahzad Sharif,Islam Ullah Khan
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811008324
Abstract: The CeIV atom in the title salt, {(H3NCH2CH2CH2NH3)2[Ce(SO4)4(H2O)]·2H2O}n, exists in a monocapped square-antiprismatic coordination geometry. The water-coordinated metal atom is bonded to four sulfate ions; one of them is monodentate and two function in a chelating mode. The fourth is also chelating but it uses one of the other two O atoms to bind to an adjacent metal atom, generating a polyanionic chain. The cations are linked to the polyanionic chain as well as to the uncoordinated water molecules, resulting in an O—H...O and N—H...O hydrogen-bonded three-dimensional network.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s160053681003789x
Abstract: The structure of the title sulfonamide, C12H15Cl2NO2S, features a distorted tetrahedral geometry for the S atom [maximum deviation: O—S—O = 120.23 (14)°]. One of the sulfonamide O atoms is coplanar with the benzene ring [C—C—S—O torsion angle = 174.5 (2)°], whereas the other lies well above the plane [C—C—S—O = 57.0 (3)°]. A chair conformation is found for the cyclohexyl ring. In the crystal, supramolecular chains aligned along the c axis are formed via N—H...O hydrogen bonds; these are consolidated in the three-dimensional packing by C—H...O contacts involving the second sulfonamide O atom.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810027698
Abstract: A folded conformation is found for the title compound, C15H16N2O3S, whereby the benzene rings come into close proximity [centroid–centroid distance = 4.0357 (12) and the dihedral angle between them = 24.37 (10)°]. The amide group is coplanar with the benzene ring to which it is bound [C—C—N—C torsion angle = 11.1 (3)°]. In the crystal packing, two-dimensional arrays in the (101) plane are formed via N—H...O hydrogen bonding.
Methyl 2-(2-amino-1,3-thiazol-4-yl)-2-[(Z)-methoxycarbonylmethoxyimino]ethanoate
Shahzad Sharif,M. Nawaz Tahir,Islam Ullah Khan,Sarfraz Ahmad
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809007661
Abstract: In the molecule of the title compound, C9H11N3O5S, the thiazole ring is oriented at dihedral angles of 87.33 (3) and 87.18 (3)° with respect to the planar (r.m.s. deviations 0.0136 and 0.0139 ) methyl ester groups. The dihedral angle between the methyl ester groups is 44.20 (3)°. In the crystal structure, intermolecular N—H...N, N—H...O and C—H...O hydrogen bonds link the molecules along the a axis, through R22(8) and R22(22) ring motifs, forming infinite two-dimensional polymeric sheets. π–π Contacts between the thiazole rings [centroid–centroid distance = 3.536 (2) ] may further stabilize the structure.
