IT Governance Maturity and Its Impact on Organizational Performance

Nowadays the critical role of using information technology in business activities is well known, and its importance has been proven both in practice and scientifically in various fields. In the current era, the existence of many facilities in the field of IT, as well as the existence of various technologies in business, raises the question in mind that to what extent the use of these technologies will be in line with the business goals of the organization? To achieve long-term goals, organizations develop strategic plans and always try to consider IT-based strategies and choose their IT investment and management as a strategy. How these strategies aligned with each other, identified and measured needs to be explored. ITGI (Information Technology Governance Institute), one of the most reputable authorities in the field of information technology infrastructure, introduced a tool called COBIT. Through monitoring and evaluation of 34 IT processes in four areas of planning, implementation, support, and evaluation, this tool depicts the competitiveness of the organization and aligns business strategies with IT strategies, which is the most important goal of governance Evaluates and measures information technology

Impact of Effective IT Governance on Organizational Performance and Economic Growth in Canada

During the last decade, information technology (IT) has been playing a more important role for organizations in achieving their goals. Recently, information technology governance (ITG) has become a critical issue for many companies in various industries. This study aims to examine the importance of information technology governance on organization success and economic growth in Canada. Structural Equation Modeling (SEM) will be used for testing the developed hypotheses generating from the theoretical framework of the study. The data will be obtained from managers in the Information and Communications Technology (ICT) industry; Samples will be selected from eight provinces of Canada (British Colombia, Ontario, Alberta, Saskatchewan, Manitoba, Nova Scotia, New Brunswick, and Prince Edward Island). This topic of research has considerable significance in Canada; a significant contribution of this study is the construction of a theoretically based model that assimilates the effective information technology governance, and organizational performance, and Economic growth of Canada.  By considering the impact of effective IT governance and organizational performance in the Canadian Information and Communications Technology sector, effective IT governance could improve organization performance which leads to a positive impact on Canadian economic growth

An Improvement on Selective Separation by Applying Ultrasound to Rougher and Re-Cleaner Stages of Copper Flotation

It has been known that the power ultrasound is used as a pretreatment and rarely applied as a simultaneous method to improve grade and recovery during froth flotation processes. This work aimed at investigating the impact of simultaneously used ultrasonic waves under variant operating configurations on the flotation of representative porphyry copper ore during rougher and re-cleaner stages. For this purpose, four different operating outlines were examined as (I) conventional flotation, (II) homogenizer, (III) ultrasonic bath, and (IV) combination of a homogenizer and an ultrasonic bath. The ultrasonic vibration was generated by the homogenizer (21 kHz, 1 kW) in the froth zone and ultrasonic bath (35 kHz, 0.3 kW) in the bulk zone. The rougher and re-cleaner flotation experiments were conducted using Denver-type mechanically agitated cells with 4.2 and 1 L capacities, respectively. The results showed that using the homogenizer (at 0.4 kW) slightly affected the selectivity separation index of chalcopyrite and pyrite, although it positively increased the grade of chalcopyrite from 21.5% to 25.7%. The ultrasonic-assisted flotation experiments with the ultrasonic bath and its combination with the homogenizer (0.4 kW) (i.e., configurations III and IV) led to an increase of approximately 16.1% and 26.9% in the chalcopyrite selectivity index compared to the conventional flotation, respectively. At the cleaning stage, a lower grade of aluminum silicate-based minerals was obtained desirably in every ultrasonic-treated configuration, which was supported with the water recoveries. Finally, applying the homogenizer and its combination with the ultrasonic bath were recommended for re-cleaner and rougher stages, respectively. Further fundamental and practical knowledge gaps required to be studied were highlighted
