In the present PhD work, three sophisticated models based on the "Engineering" modeling approach have been utilized to conveniently describe and thoroughly analyze details of Lightning events at the CN Tower. Both the CN Tower and the Lightning Channel are represented by a number of connected in series Transmission Line sections in order to account for the variations in the shape of the tower and for plasma processes that take place within the Lightning Channel. A sum of two Heidler functions is used to describe the "uncontaminated" Return Stroke current, which is injected at the attachment point between the CN Tower and the Lightning Channel. Reflections and refractions at all points of mismatched impedances are considered until their contribution becomes less than 1% of the originally injected current wave. In the proposed models, the problem with the current discontinuity at the Lightning Channel front, commonly taken care of by introducing a "turn-on" term when computing radiation fields, is uniquely treated by introducing reflected and transmitted components. For the first time, variable speed of propagation of the Return Stroke current front has been considered and its influence upon the predicted current distributions along the whole Lightning Channel path and upon the radiated distant fields analyzed. Furthermore, as another novelty, computation of the electromagnetic field is accomplished in Cartesian Coordinates. This fact permits to relax the requirement on the verticality of the Lightning Channel, normally imposed in Cylindrical Coordinates. Therefore, it becomes possible to study without difficulty the influence of a slanted Lightning Channel upon the surrounding electromagnetic field. Since the proposed sophisticated Five-Section Model has the capability to represent very closely the structure of the CN Tower and to emulate faithfully the shape of, as well as physical processes within the Lightning Channel, it is believed to have the potential of truthfully reproducing observed fields. The developed modeling approach can be easily adapted to study the anticipated radiated fields at tall structures even before construction.

Against the backdrop of the brain drain-brain gain debate, this thesis explores certain facets of the return migration phenomenon. Drawing on several theories, the decision to return among high skilled migrants is likely to be influenced by the prospect of using their overseas-acquired knowledge to secure a better livelihood back home. While ample consideration is given to motivations to return, the choice of employer and issues adjusting to the work and social surroundings, the main objective of the research is to understand migrants' transfer of overseas-acquired knowledge upon their return to India. Given the interdisciplinary nature of the topic, the scope of the thesis is focused on returnees working in two organizations in New Delhi—Fortis Escorts Hospital and Research Centre (EHIRC) and Tata Consultancy Services' Government Industry Solutions Unit (GISU). Adopting a mixed methods approach, survey data and case interviews are analyzed to address the core research question: “How and in which ways do returnees transfer their newly acquired knowledge, skills and experiences in employing organizations?” A key hypothesis is that returnees' social ties affect the extent and nature of knowledge transfers and thus confer intended benefits and may lead to unintended consequences for their organizations. The analyses pit McPherson's (2001) principle of homophily in social networks against Granovetter's (1973) weak ties hypothesis to grasp the role of returnees in knowledge transfers within EHIRC and GISU. Results drawn from data collected on returnees, non-migrants and transnationals strongly confirm that social ties—strong, intermediate or weak—affect the transfer of knowledge to stakeholders in their organizations. The contribution of this thesis to the existing body of research is to shed light on both the potential and limitations of returnees as a conduit for transferring knowledge, upgrading skills and relaying insights to non-migrants, teams or units in the workplace.

Little is known about time to return to work (TRTW) following planned medical events. This study was a secondary analysis (n=94) to determine predictors of time to return to work following a total knee replacement for osteoarthritis. Significant predictors of delayed TRTW following a knee replacement: 1) use of workplace modifications (in 6wks vs 5 wks) and 2) poor physical function (in 7wks vs 6 wks). These findings have large implications for workers undergoing knee replacement, orthopedic clinicians, and occupational health nurses.

<p>CEO compensation is a relevant topic in today's society that touches both political and economic questions which are of interest for the whole general public.

These variables are collected from each company's annual reports and which we have chosen to focus on the two past years 2007 and 2008, as it is the most recent data. For the principle of our thesis a combination of qualitative and quantitative methods was applied, to best suite the purpose. When finding a sustainable and significant result, regressions of different variables from the annual reports were drawn and the outcomes of these were interpreted and analyzed. Our findings show that turnover is the only variable which indicated any significant p-value in the regressions drawn. Of all regressions three show significance and all arerelated to turnover.
