The present Ph.D thesis deals with feedforward (open-loop) control methods, in clas- sical and quasi-classical physical systems like nonlinear oscillators, quantum particles in external electromagnetic field etc. We investigate the special case of fast oscillating control when the time of control period is sufficiently less to compare with the typical time of controlled system behavior ( for instance its period of oscillation). We apply mathematical technique specially developed for feedforward control systems such as Lyapunov method and Kapitza averaging. First we demonstrate that the Lyapunov spectrum of Kapitza averaged systems are sufficiently different from the original spectra of non-controlled plants. That means the description of averaged system in the neighborhood of their fixed points does not describe appropriately the original system behavior. Secondly we apply Kapitza averaging procedure to the original systems to derive the correcting terms in their dynamical equations. As a result we demonstrate re-design of original dynamical systems by fast changing control periodical force.

انا

حالات کی اک ضرب نے دیکھو
ایسی رُت بھی کھولی تھی

کہ ہم تم جو یکجاں بہت تھے
دور بہت جا بیٹھے تھے

دل کو پر گماں تھا یہ
غلط نہیں ہے تو پر تجھ سے

اس رُت میں غلط ہو رہا ہے
گردش کا یہ کھیل ہے شاید

دل کی ان زمینوں پہ
جو فاصلے بو رہا ہے

اس سب میں تو بھی تھک گئی تھی
چلتے چلتے رُک گئی تھی

میں بھی ٹھیک تھا اپنے تئیں
رُک گیا تھا میں بھی وئیں

پر تجھ سے یوں بچھڑنے کو
میں نے بہتر سمجھا مرنے کو

اُٹھا میں اپنے کمرے بند سے
تیرے پیروں میں انا دھرنے کو
میں آیا سب ٹھیک کرنے کو

COVID-19 Vaccine Uptake in Pakistan: No Time to Err

COVID 19 pandemic has had a significant impact on social, physical, mental and financial aspects of human life. Among the sickness and despair experienced for last more than a year, COVID vaccination is a ray of hope. The uptake of COVID vaccines has remained low. The government, institutions as well healthcare professionals should take this responsibility of promoting vaccination. A strong will and simple nudges are what it takes to fight the menace of the COVID pandemic.

Relationship Between Workplace Mistreatment and On-Job Behavior Psychological Capital As Moderator

Workplace mistreatment is a workplace stressor which has adverse effect on work outcomes. Due to its inimical consequences, an ample of research has been conducted during last few years to cope mistreatment at workplace. This study investigates the moderating role of psychological capital on the relationship between workplace mistreatment (workplace incivility, abusive supervision, workplace mobbing) and on-job behaviors (job performance, organizational citizenship behavior towards organization, organizational citizenship behavior towards individuals and counterproductive work behavior towards organization, counterproductive behavior towards individuals). Multisource data was collected through questionnaires from faculty members serving in universities in Pakistan. The data for independent variables i.e. workplace mistreatment and moderating variable i.e. psychological capital was collected from 408 faculty members in first step, the data for on-job behaviors (job performance, organizational citizenship behavior towards organization, organization citizenship behavior towards individuals) was collected from their supervisors and data for (counterproductive work behavior towards organization, counterproductive behavior towards individuals) was collected from their peers. The results of the study revealed that workplace mistreatment (workplace incivility, abusive supervision, workplace mobbing) has significant relationship with and job performance, organizational citizenship behavior towards organization, organizational citizenship behavior towards individuals. The results also revealed that psychological capital moderates the relationship between workplace mistreatment (workplace incivility, abusive supervision, workplace mobbing) and job performance, organizational citizenship xvi behavior towards organization, organizational citizenship behavior towards individuals. However, in case of counterproductive work behavior towards organization, counterproductive behavior towards individuals, diverse results are revealed. Guidelines and recommendations are provided to Higher Education Commission, Pakistan and university management to tackle workplace mistreatment in the universities in Pakistan. Future research directions are discussed
