Leader-Member Exchange Quality and employee work behaviours: Mediating Role of Interactional Justice

The study aims to examine the mediating role of interactional justice between LMX quality and employee’s in-role behaviour and citizenship behaviour. Adam’s equity theory and social exchange theory are employed o explain the theoretical framework. Proposed mediation model is tested using time lagged data of 308 responses from service sector of Pakistan. To examine validity of the measures, confirmatory factor analysis has been done. The measurement model produced better indices for five factors. Structure equation modelling technique has been used to test mediation model. Results supported the hypothesis of mediation. Finally managerial implications and future research directions have been discussed. Keywords: LMX quality, Interactional Justice, Organization citizenship behaviour (OCB), In-role behavior (IRB)

Correlation of Fine Needle Aspiration Cytology and Histopathology Diagnosis in the Evaluation of Breast Lumps

Background: A large number of patients have been suffer from breast cancer worldwide and this trend is increasing. It is difficult to determine whether a lump is benign or malignant from clinical assessment; thus, the need for micropic and tissue analysis arises. Methods: This comparative retrospective cross sectional study was conducted in the Department of Pathology, Rehman Medical Institute, Peshawar, Pakistan from January 2006 to March 2013, to determine the value of fine needle aspiration cytology (FNAC) in the diagnosis of breast lump and to compare the result of FNAC with histological diagnosis to assess its accuracy. Results: Seventy-four  cases with breast lumps were presented for FNAC. Of these, 32.4% were reported as a C2 lesion, 4.1% were reported as benign with atypical cells (C3), 8.1% cases were suspicious for malignancy (C4), and 55.4% were positive for malignancy (C5). On histopathology examination, out of 24 cases which were reported as C2 lesions, 95.8% were benign and 4.1% turned out to be invasive ductal carcinoma. Of the cases that presented as C3 lesions, one was diagnosed as benign duct ectasia, one with ductal carcinoma in situ, and one with invasive ductal carcinoma on histopathological examination. The cases that were diagnosed as C4 lesions all turned out to be carcinoma on histopathology.  In this study, FNAC and histopathology diagnoses were strongly correlated [r 0.92, p <0.001]. Conclusion: Diagnosis of breast lump based on FNAC should be practiced as there is high correlation with histopathological finding. FNAC should be used as a routine..

Work Stress of Teachers from Government Girls’ Secondary Schools Karachi

Teacher is a well-known profession all over the world. But now a days crisis of quality education can be prominently seen. Among elements effecting teachers’ productivity “Stress” is one of the core elements raising poor productivity by the teachers. Stress is expanding due to various issues. Although, stress is not always playing a negative role in person’s productivity, as at some levels stress tends to accelerate focus of a person, which makes the productivity better. But unfortunately, in secondary school teachers are confronting some common stress generating elements all over Karachi. Those elements are not impacting their professional life positively. The purpose of this study is to determine the common stress generating elements and their impacts on teachers’ productivity. Going through both qualitative by teachers interview and on the bases of interviews developed lickert scale closed ended questionnaire, distributed to 50 male and female teachers, among which 45 teachers responded. Data was analyzed by SPSS. According to the results there is a need of betterment of some policies on management grounds in order to overcome the stress generating elements.

1-(5-Hydr­oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone: a new monoclinic polymorph

The title compound, C12H12N2O2, crystallized in the monolinic space group P21/n, with two independent mol­ecules (A and B) in the asymmetric unit. This is in contrast to the first monoclinic polymorph reported [Cingolani et al. (2002 ▶). Inorg. Chem. 41, 1151–116], which crystallized in the space group C2/c with one independent mol­ecule per asymmetric unit. The dihedral angles between the two rings differ slightly; in mol­ecule A it is 4.90 (11)° and in mol­ecule B it is 16.05 (13)°. In both mol­ecules, there is an intra­molecular O—H⋯O hydrogen bond involving the hydroxyl substituent and the carbonyl O atom of the adjacent acetyl group. In the crystal structure, mol­ecules A and B are linked via a C—H⋯N inter­action. There are also some weak C—H⋯π inter­actions involving the phenyl ring of mol­ecule A and H atoms of the acetyl groups of both mol­ecules

Indirect Extrusion: A Multifaceted Approach of Sub-surface Tubular Expansion

Extrusion and indirect extrusion is a very old manufacturing process used in multitudes of applications mainly focused on transportation, household and power industries. Indirect extrusion has found an interesting application in petroleum industry, which resulted in resolving many unsolvable issues over the last few decades. The current and expected future global demand for hydrocarbons became a driving force for researchers to find new comprehensive and cheaper solutions for hydrocarbon production. The challenges faced in oil and gas fields, while drilling, constructing and operating new and old vertical/horizontal wells, are many. The use of indirect extrusion for in-situ expansion of sub-surface tubulars used in wells revolutionized the drilling and completion as opposed to one and half decade back. The emergence of solid expandable tubular technology has changed the basics of how we design and construct wells. The original development of the technology was to overcome the challenges faced by the petroleum industry to reach ultra-deep reservoirs, off-shore drilling, drilling in high-pressure/difficult zones and repair/maintenance of old/ageing wells. However, it gained significant interest of researchers and operators in providing solutions to wide-range problems. The development of a computational framework using finite element method (FEM) enabled to determine the force required for expansion and resulting dimensional changes in final product, which is of direct assistance to the field engineers. The effect of friction and stress variations along contact surface is also determined
