Debate emanating from management research and practice has been particularly on the development of a framework that will effectuate organizational performance while addressing external factors. Dynamic capabilities framework has been discussed widely since it incorporates the creation, modification and reconfiguration of assets in an environment characterised by technological advancements. Management capabilities in this case play an important role of recombination of resources and capabilities. Technology orientation is equally of great importance is it lays down ways in which organizations conduct their business activities especially towards customers’ satisfaction, technological development, improvement through learning and entrepreneurial aspects like innovation and risk taking. External environment is critical in every decision making process especially the threat of new entrants if there is a weak intellectual property regime to guard the valuable assets. It is evident that there are a limited number of properly operationalised empirical studies that have been conducted on dynamic capabilities and investigations tend to be case-based and qualitative. Additionally, few studies have not been able to relate and distinguish technology orientation and dynamic capabilities. This study, therefore, seeks to critically examine the role of technology orientation in development of dynamic capabilities which encompass managerial and organizational processes, firm’s endowments and its available strategic alternatives and its attractiveness of opportunities which lie ahead and hence high organizational performance. The need to tighten the dynamic capabilities framework as a basis for extensive empirical research in strategic management has been addressed in this review as it shows a relationship with technology orientation in achieving superior firm performance. Key Words: Dynamic Capabilities, Technology Orientation, Environmental dynamism, Path Dependency

Mitigation of Single Phase Voltage Sag, Swell and Outage Using Voltage Controlled Voltage Source []

In this paper, a single phase sag and swell compensator is realized using a voltage controlled voltage source to mitigate voltage sag and swell in one phase when the voltages in other two phases are in rated condition. Each single phase compensator is constructed using one multi winding transformer, two bidirectional switches, voltage controlled voltage source and a series transformer. As each converter operates independently the compensator can properly compensate single phase voltage sag and swell. They can also compensate long-time voltage sags and swells as the power required for compensation is taken from the grid. For compensation, the other two phase voltages are added using a multi winding transformer. The added voltage is maintained at one end of the series transformer while the other end is connected to a voltage controlled voltage source. The voltage of the voltage controlled voltage source in controlled by the voltage at the phase where the compensation is needed. No modulation technique, controller and filters are required. The simulation results verify that the proposed topology can mitigate single phase voltage sag of 100% and swell of 100% with the THD of 0%.


ABSTRACT Tax compliance refers to the degree to which a tax payer complies (or fails to comply) with tax rules to the country for instance by declaring income, filing a return and paying the tax due in a timely manner. The main objective of this research was to educate (SME’s) on the need to comply with tax payment in the Wa municipality. The survey research method was used for the research. It was used to collect data on the phenomenon with the purpose of employing the data to make more relevant recommendation to improve and enhance the current condition and practice. The study recorded a high rate of tax evasion, this tax non-compliance by SME’s do not receive any punishment as tax laws stipulated. The results of the study suggested that tax knowledge has a positive correlation with tax compliance. The study found that Ghanaian tax payer knows that taxes are the major sources of government revenue as well as the funding of public expenditures; they also have a perception that taxes paid to the government are not used for their intended purposes. The study have concluded based on the evidence that general tax knowledge has a very close relationship with taxpayers’ ability to understand the laws and regulations of taxation, and their ability to comply with them. The study recommends the implementation of Pay as You Earned (PAYE) policy, which makes it difficult to evade tax as deductions are made at source.
