    This study analyzes the impact of different governance related variables on the corporate governance disclosure level of Pakistani manufacturing firms. The study period is one year i.e. 2014 and it used a sample of 50 manufacturing firms which are classified into five different categories. The analyses are done through OLS regression. A comprehensive disclosure index consisting the thirty different disclosure items is developed which served as dependent variable. Thirty disclosure items are included in the index according to the disclosure requirements of SECP code of corporate governance. Board independence, managerial ownership, foreign ownership, block holdings and audit firm status are used as corporate governance related independent variables. The results indicate that the CG disclosure level of selected manufacturing firms is positively influenced by board independence, foreign ownership, block holding ownership and audit firm status. However the results of managerial ownership variable are not statically significant and the hypothesis regarding to this variable is rejected. The study found that all the independent variables except managerial ownership are the important determinants of CG disclosure. Keywords: CGD, INDE’s, SEC

    Objectives: Patient satisfaction is a significant marker for estimating the quality of medical services being provided at a clinical facility. It also influences the opportune, proficient, and patient-focused provision of quality medical services. Methods: Data from 768 outdoor patients were collected from four tertiary care hospitals in Islamabad, Pakistan. Half of the patients were from public sector hospitals, while others were from private hospitals. A self-administered questionnaire (Cronbach’s alpha=0.896) was structured for data collection. Using SPSS, descriptive statistics, independent t-test, and Chi-square test were used to analyze data. Results: Overall, 51.4% of patients were satisfied with the services provided to them at hospital Outpatient department. Patients who experienced private sector hospitals (74%) were significantly more satisfied than those who visited the public sector hospitals (29%) (p<0.001). Gender-wise, female patients were more satisfied (58%) than male patients (47%). Insufficient attention of the doctor, the behavior of the supporting staff and inadequate management of disease record were the red flags highlighted by the patients. Conclusion: The current investigation has shown that quality healthcare is significantly associated with economic conditions; patients’ perspective have expressed that the private sector provides satisfactory medical services at a high expense, whereas the public sector is a less expensive alternative but it lags in the provision of high-quality services and patient satisfaction

    Incoherent and Online Dictionary Learning Algorithm for Motion Prediction

    Accurate model development and efficient representations of multivariate trajectories are crucial to understanding the behavioral patterns of pedestrian motion. Most of the existing algorithms use offline learning approaches to learn such motion behaviors. However, these approaches cannot take advantage of the streams of data that are available after training has concluded, and typically are not generalizable to data that they have not seen before. To solve this problem, this paper proposes two algorithms for learning incoherent dictionaries in an offline and online manner by extending the offline augmented semi-non-negative sparse coding (ASNSC) algorithm. We do this by adding a penalty into the objective function to promote dictionary incoherence. A trajectory-modeling application is studied, where we consider the learned atoms of the dictionary as local motion primitives. We use real-world datasets to show that the dictionaries trained by the proposed algorithms have enhanced representation ability and converge quickly as compared to ASNSC. Moreover, the trained dictionaries are well conditioned. In terms of pedestrian trajectory prediction, the proposed methods are shown to be on par (and often better) with the state-of-the-art algorithms in pedestrian trajectory prediction

    Purpose: To synthesize and characterize some new gabapentin Schiff base derivatives, and to assess their antibacterial, antioxidant and antiepileptic activities.Methods: Four Schiff base derivatives of gabapentin, termed G1, G2, G3 and G4, were synthesized by condensation with benzoin, vanillin, acetophenone, and benzophenone, respectively. Their chemical identities were established by FTIR, 1 H NMR and 13C NMR techniques. The new compounds were screened for antibacterial activity using agar well method, antioxidant activity by DPPH assay, and anticonvulsant activity against pentylenetetrazole (PTZ) induced seizures in mice.Results: All the compounds showed antibacterial activity against the test strains to variable degrees, while the parent drug did not exhibit antibacterial activity. The zones of inhibition of compound G2 against Micrococcus luteus (36.2 ± 1.0 mm) and Serratia marcescens (28.2 ± 1.0 mm), and of compound G4 against Stenotrophomonas maltophilia (36.8 ± 1.0 mm) were larger compared to thestandard drug, doxycycline, exhibiting zones of inhibition 28.2 ± 1.3, 28.2 ± 0.9 and 20.0 ± 0.9 mm, respectively. In addition, compounds G1 and G2 possessed significantly greater (p < 0.05) radical scavenging activity (82.3 ± 1.8 and 92.3 ± 2.2 %, respectively) than the precursor drug, gabapentin (63.2± 2.6 %). The seizure scores for compounds G1 (0.7 ± 0.06) and G2 (0.9 ± 0.07) were comparable(p ˃ 0.05) with gabapentin (0.8 ± 0.06), while compounds G3 and G4 were less active (p < 0.05) than gabapentin.Conclusion: Compounds G1 and G2 exhibit good antibacterial and antioxidant activities while retaining the anticonvulsant activity of the parent drug, gabapentin, thus making them suitable candidates for further development for the treatment of neurodegenerative pathologies associated with bacterial infections.

    Background: Hemodialysis patients are vulnerable to infections with Hepatitis B Virus and hepatitis C virus (HCV). Patients who are on maintenance hemodialysis are considered as high-risk group for acquiring hepatitis B virus, resulting in high morbidity and mortality. Therefore, to vaccinate them against the virus is mandatory. Compared to a response rate of over 90% in the normal population, only 50 to 60% of those with end-stage renal disease achieve adequate antibody levels following immunization and the objective of this study was to determine the antibody level after Hepatitis B vaccination in chronic hemodialysis patients. Methods: 118 patients, undergoing chronic hemodialysis (HD) at the dialysis unit of Liaquat National Hospital, fulfilling the inclusion and exclusion criteria were enrolled between April 2013 and September 2013, after taking informed consent and approval from ethical review committee. AntiHbs (Hepatitis B surface antibody) titers were measured. Patients were differentiated as Immune and non immune based on antibody titers, with levels of >10IU/l being considered as immune and levels of <10IU/las non immune. AntiHbs titer was measured by ELISA (Enzyme Linked Immunosorbant Assay). Data was analyzed using SPSS version 14.0 for windows. Chi square test were used to ascertain the statistical significance. P value <0.05 was taken as statistically significant. In addition, the effect of age, gender and duration of Hemodialysis on antibody titer was also observed. Results: Out of 118 patients enrolled, 103 (87.3%) had an adequate antibody response and were considered immune while only 15 patients (12.7%) had an inadequate antibody response rendering them non immune. AntiHbs titers showed no significant co-relation with gender and duration of Hemodialysis therapy(p>0.05), while age was found to have significant correlation as younger age group (<60years) had more immune response (p<0.001). Conclusion: Our study showed a very good antibody response to Hepatitis B vaccination among hemodialysis patients that correlated with age with younger age group having a better response but no correlation to gender and duration of dialysis.
