THE IMPACT OF MOTIVATIONAL FACTORS ON ORGANIZATIONAL LEARNING: A STUDY ON EDUCATION SECTOR OF PAKISTAN

The main purpose of this study is to investigate the motivational factors that affect the organizational learning in the education sector of Pakistan. Self-administrated questionnaire with 5 point Likert scale is used for primary data collection and research journals and articles are used for secondary data collection. The sample size of the study is consisted of hundred academic employees of different educational institutes of Lahore. SPSS is used for measuring the relationships between variables and interpretations of their relationship. Organizational learning mainly depends upon peer cooperation motivational factor. As the peer cooperation increases in an organization, it leads the organization towards learning. Peer cooperation has  a strong effect on organizational learning as a motivational factor in the education sector. A high level of peer cooperation in any organization helps in enhancing its learning. Furthermore, according to data analysis all other motivational factors used in this study i.e. working condition, recognition and reward has very small or no effect on learning of any organization. So, we can conclude that, among four different motivational factors i.e. peer cooperation, working condition, recognition and rewards, only peer cooperation has a strong relationship with organizational learning as compared to other factors

Effect of Medium of Instruction on Students’ Motivation Towards Learning at Secondary Level

The present study aimed to investigate the effect of medium of instruction on students’ motivation towards learning at secondary level. It comprised of 1456 respondents as a sample of the study which were conveniently selected from public and private sector secondary schools from the district Kasur of Punjab province.Motivation scale towards learning by Sultana, (2014) having 20 Likert type items with a reliability coefficient value 0.85 was used for data collection.Findings of the study revealed that the medium of instruction had no significant effect on motivation level of students towards learning. On the basis of gender there was found no significant effect on motivation level. There was significant difference between English and Urdu mediums urban respondents’ motivation level as urban English medium students had significantly higher motivation level than urban Urdu medium students. There was significant difference between English and Urdu mediums rural respondents’ motivation level as rural Urdu medium students had significantly higher motivation level than rural English medium students. It was recommended that the findings of the study should be refined for further implications through further longitudinal studies with more data from other provinces of Pakistan

Effect of Cooperative Learning on Students’ Achievement in English Tenses

The present study aimed to find out the effect of cooperative learning onsecondary school students’ achievement in English tenses. In thisresearch pre-test posttest control group only design was used. On thebasis of 8th grade students’ scores in the subject of English conducted byPunjab Education Commission (PEC), sixty students of ninth grade, whowere enrolled in a public school, were divided into experimental andcontrol groups by using matched-pair technique. A teacher made test wasconducted as pre-test and post-test for both groups. No significantdifference was found in pre-test scores of experimental and controlgroups. The experimental group was treated by STAD (Student TeamAchievement Division) method of cooperative learning while controlgroup was taught by traditional learning under the control condition for aperiod for eight weeks. Analysis of the data revealed the performance ofexperimental group was significantly better than that of control group.Hence, it was concluded that cooperative learning was betterinstructional strategy for increasing the student achievement in Englishtenses. By viewing the information obtained by this study, the secondaryschool English teachers may be in a position to improve their teachingmethodology. Keeping in view the results of the study, curriculumdesigners and policy makers may be able to incorporate cooperativelearning as the methodological aspect of the curriculum. On the wholethe study will be useful for teachers, educationists, curriculumdevelopers, policy makers and educational administrators

Posterior Lumbar Interbody Fusion in Degenerative Lumbar Spine Disease and Risk of Adjacent Segment Disease

Objective:  To determine the chances of adjacent segment disease (ASD) and risk factors after posterior lumbar interbody fusion (PLIF). Material and Methods: 110 patients of both genders with degenerative lumbar instability at L4/5 level were included in my study. We did PLIF in all our patients and followed our patients for one year. The following parameters were measured: the degree of lumbar lordosis, the degree lumbosacral angle, the disc space height and their dynamic angulation and the displacement of L3 over L4. We checked the outcome with the help of the Japanese orthopedic association (JOA) and Oswestry disability index (ODI). We divided the patients into groups A and B; group A includes patients with progression of degeneration at the proximal level (L3-L4), while group B with no progression of disease at proximal level. Results:  The 86 patients (78.18%) were in group A, and 24 patients (21.88%) were in group B. There were no significant difference in radiological parameters of both groups; lumbosacral angle of lordosis, L3 laminar inclination angle, preoperative degenerative changes at proximal level, L4–L5 lordosis and BMD before surgery. The clinically and statistically significant differenceswere of the age of the patients falling in two groups. We found that at the completion of study ODI and JOA were not significantly different in both groups (P >0.05). Conclusion:  Degenerative lumbar disease is an age related disease with no significant effect of radiological degenerations on the final outcome of our patients.No other possible risk factor has a significant effect on outcome

Outcome of Lateral Mass Fixation and Fusion – A Comprehensive Analytical Study of 205 Lateral Mass Screws in 35 Patients at Punjab Institute of Neurosciences

Objective: To see outcome, accuracy and expected complications in passing lateral mass screws in patients with cervical spine injury, degenerative disease at the cervical spine level and neoplastic lesions.Materials and Methods: In this study, 35 patients were included and 205 screws passed in lateral mass patients’age ranged from 12-70 years (25 males and 10 females) with trauma to the cervical spine, degenerative disease at the cervical spine level and Intradural extramedullary benigntumors and extradural malignant neoplasm.Patients less than 12 years and more than 65 years of age,patients with traumatic ruptured disc causingspinal cord compression anteriorly and operated for cervical spine were excluded from our study.In all patients,we did lateral mass fixation with polyaxial screws and rods under fluoroscopic assistance.For assessment of screws trajectory and position, CT scan cervical spine with 3D reconstruction was performed on a first post op day to confirm screw orientation and direction and for fascet, foraminal, foramen transversarium violations.Results: All screws were passed by using Megrel’s trajectories. Not a single patient had nerve root, cord injury nor vertebral artery injury. One patient had screw pullouts requiring reoperation.12 to 14mm size screws were used under fluoro guidance. On postoperative CT cervical spine with 3D reconstruction shows no breach or violations of any foramen transversarium, nerve root injury or neural foramen penetration by screws. In all patients polyaxial screw/rod construct was used. Conclusion: Cervical spine lateral mass fixation with polyaxial screws is a safe and effective technique in expert hands under fluoroscopic assistance

Objective: To asses the outcome of transoral microsurgical excision of anterior placed craniovertebral junction (CVJ) lesions excision followed by posterior craniocervical stabilization. Study Design: Qausi Experimental study. Setting: Department of neurosurgery PINS/Lahore General Hospital, Lahore. from May 2017 to Aug 2018. Inclusion Criteria: Male and Female patients of 12-65 yrs of age with compressive lesion at the ventral aspect of craniovertabral junction. Exclusion Criteria: Lateral and posterolateral lesions, lesion below C2 vertebral body, patient unfit for anaesthesia and surgery. Material and Methods: 12 consecutive patients coming in OPD and emergency department of our unit and fulfilling the inclusion criteria were studied. All patients were prepared for the surgery and written informed consent taken from all our patients. The patients underwent anterior trans oral microsurgical excision of the tumour followed by posterior fixation. Results: Out of 12 patients (range 12–65 years); Rheumatoid arthritis in 1 patient, tumor in 5 patients or trauma in 4 case and basilar invaginations in 2 patients. All my patients had headache (cranial and/or high-cervical pain), 73% of patients presented with quadriparesis, and 29% presented with basal cranial nerves involvements. Anterior decompression followed by posterior craniocervical fixations was done in all patients in same sitting. Out of 5 patients having severe neurological deficits preoperatively 3 improved. The remaining 7 patients have mild to moderate neurological deficits improved gradually throughout the follow-up periods to independent level. Among complications mortality in 1 patient and morbidity in the form of dural tear, CSF leak and infection in 2 patient). Craniocervical instability was seen in one patients after 3 months of surgery. Conclusion: A good surgery with proper decompression at the craniovertebral junction is technically difficult procedure and demands expertise. It needs proper preoperative planning and investigations and adequate decompression and stabilization with proper implants

Ficus benghalensis as Potential Inhibitor of 5α-Reductase for Hair Growth Promotion: In Vitro, In Silico, and In Vivo Evaluation

The screening of hair follicles, dermal papilla cells, and keratinocytes through in vitro, in vivo, and histology has previously been reported to combat alopecia. Ficus benghalensis has been used conventionally to cure skin and hair disorders, although its effect on 5α-reductase II is still unknown. Currently, we aim to analyze the phytotherapeutic impact of F. benghalensis leaf extracts (FBLEs) for promoting hair growth in rabbits along with in vitro inhibition of the steroid isozyme 5α-reductase II. The inhibition of 5α-reductase II by FBLEs was assessed by RP-HPLC, using the NADPH cofactor as the reaction initiator and Minoxin (5%) as a positive control. In silico studies were performed using AutoDock Vina to visualize the interaction between 5α-reductase II and the reported phytoconstituents present in FBLEs. Hair growth in female albino rabbits was investigated by applying an oral dose of the FBLE formulation and control drug to the skin once a day. The skin tissues were examined by histology to see hair follicles. Further, FAAS, FTIR, and antioxidants were performed to check the trace elements and secondary metabolites in the FBLEs. The results of RP-HPLC and the binding energies showed that FBLEs reduced the catalytic activity of 5α-reductase II and improved cell proliferation in rabbits. The statistical analysis (p 70%) suggested that hydroalcoholic FBLE has more potential in increasing hair growth by elongating hair follicle’s anagen phase. FAAS, FTIR, and antioxidant experiments revealed sufficient concentrations of Zn, Cu, K, and Fe, together with the presence of polyphenols and scavenging activity in FBLE. Overall, we found that FBLEs are potent in stimulating hair follicle maturation by reducing the 5α-reductase II action, so they may serve as a principal choice in de novo drug designing to treat hair loss
