Remolding a company through a compliance program : the case of Siemens

Abstract : Since at least the 1980's, a growing number of companies have set up an ethics or a compliance program within their organization. However, in the field of study of business management, there is a paucity of research studies concerning these management systems. This observation warranted the present investigation of one company's compliance program. Compliance programs are set up so that individuals working within an organization observe the laws and regulations which pertain to their work. This study used a constructivist grounded theory methodology to examine the process by which a specific compliance program, that of Siemens Canada Limited, was implemented throughout its organization. In conformity with this methodology, instead of proceeding with the investigation in accordance to a particular theoretical framework, the study established a number of theoretical constructs used strictly as reference points. The study's research question was stated as: what are the characteristics of the process by which Siemens' compliance program integrated itself into the existing organizational structure and gained employee acceptance? Data consisted of documents produced by the company and of interviews done with twenty-four managers working for Siemens Canada Limited. The researcher used QSR-Nvivo computer assisted software to code transcripts and to help with analyzing interviews and documents. Triangulation was done by using a number of analysis techniques and by constantly comparing findings with extant theory. A descriptive model of the implementation process grounded in the experience of participants and in the contents of the documents emerged from the data. The process was called "Remolding"; remolding being the core category having emerged. This main process consisted of two sub-processes identified as "embedding" and "appraising." The investigation was able to provide a detailed account of the appraising process. It identified that employees appraised the compliance program according to three facets: the impact of the program on the employee's daily activities, the relationship employees have with the local compliance organization, and the relationship employees have with the corporate ethics identity. The study suggests that a company who is entertaining the idea of implementing a compliance program should consider all three facets. In particular, it suggests that any company interested in designing and implementing a compliance program should pay particular attention to its corporate ethics identity. This is because employee's acceptance of the program is influenced by their comparison of the company's ethics identity to their local ethics identity. Implications of the study suggest that personnel responsible for the development and organizational support of a compliance program should understand the appraisal process by which employees build their relationship with the program. The originality of this study is that it points emphatically that companies must pay special attention in developing a corporate ethics identify which is coherent, well documented and well explained.

Simplified design method for energy dissipating devices in retrofitting of seismically isolated bridges

Abstract: Highway bridges have great values in a country because in case of any natural disaster they may serve as lines to save people’s lives. Being vulnerable under significant seismic loads, different methods can be considered to design resistant highway bridges and rehabilitate the existing ones. In this study, base isolation has been considered as one efficient method in this regards which in some cases reduces significantly the seismic load effects on the structure. By reducing the ductility demand on the structure without a notable increase of strength, the structure is designed to remain elastic under seismic loads. The problem associated with the isolated bridges, especially with elastomeric bearings, can be their excessive displacements under service and seismic loads. This can defy the purpose of using elastomeric bearings for small to medium span typical bridges where expansion joints and clearances may result in significant increase of initial and maintenance cost. Thus, supplementing the structure with dampers with some stiffness can serve as a solution which in turn, however, may increase the structure base shear. The main objective of this thesis is to provide a simplified method for the evaluation of optimal parameters for dampers in isolated bridges. Firstly, performing a parametric study, some directions are given for the use of simple isolation devices such as elastomeric bearings to rehabilitate existing bridges with high importance. Parameters like geometry of the bridge, code provisions and the type of soil on which the structure is constructed have been introduced to a typical two span bridge. It is concluded that the stiffness of the substructure, soil type and special provisions in the code can determine the employment of base isolation for retrofitting of bridges. Secondly, based on the elastic response coefficient of isolated bridges, a simplified design method of dampers for seismically isolated regular highway bridges has been presented in this study. By setting objectives for reduction of displacement and base shear variation, the required stiffness and damping of a hysteretic damper can be determined. By modelling a typical two span bridge, numerical analyses have followed to verify the effectiveness of the method. The method has been used to identify equivalent linear parameters and subsequently, nonlinear parameters of hysteretic damper for various designated scenarios of displacement and base shear requirements. Comparison of the results of the nonlinear numerical model without damper and with damper has shown that the method is sufficiently accurate. Finally, an innovative and simple hysteretic steel damper was designed. Five specimens were fabricated from two steel grades and were tested accompanying a real scale elastomeric isolator in the structural laboratory of the Université de Sherbrooke. The test procedure was to characterize the specimens by cyclic displacement controlled tests and subsequently to test them by real-time dynamic substructuring (RTDS) method. The test results were then used to establish a numerical model of the system which went through nonlinear time history analyses under several earthquakes. The outcome of the experimental and numerical showed an acceptable conformity with the simplified method.
