Challenging Environment

Several authors argued that strategic planning is limited and not producing the needed outcomes. In today’s increasingly challenging environment, it is argued that public sector organizations are expected to shift from traditional strategic planning to the strategic management approach in order to achieve their desired outcomes. Previous research has focused almost upon developed, and not on developing countries, for instance, the Kingdom of Bahrain. This study will be the first of its kind to focus on strategic management practices based on the new strategy of Bahrain for 2030. Using quantitative survey method, this paper aims to explore the progress of the transition from strategic planning to the strategic management approach in the public sector of Bahrain, and then the paper explores the elements that are related to successful strategic management approach in these organizations. The findings reveal that the progress in the transition from strategic planning to a strategic management approach in most of the organizations surveyed was limited. However, some of the organizations were found to be at the start of such a transition and this may be a good sign. Additionally, the findings reported many leading edge elements that are closely related to this transition.

In recent years, experimental results obtained by means of the wake survey method have indicated that the viscous drag of a ship model varies with the Froude number; later studies have tended to confirm these findings. The present work was undertaken to establish the validity of this variation. In order to avoid the principal sources of inaccuracy of previous work, modifications to the equipment were made. Also, to obtain viscous drag, the authors applied a refinement of the Betz-Tulin formula.

Identification And Quantification

A methodology has been developed and demonstrated which is capable of determining total amounts of asbestos fibers and fibrils in air ranging from as low as fractional nanograms per cubic meter (ng/m3) of air to several micrograms/m3. The method involves the collection of samples on an absolute filter and provides an unequivocal identification and quantification of the total asbestos contents including fibrils in the collected samples.The developed method depends on the trituration under controlled conditions to reduce the fibers to fibrils, separation of the asbestos fibrils from other collected air particulates (beneficiation), and the use of transmission microscopy for identification and quantification. Its validity has been tested by comparative analyses by neutron activation techniques. It can supply the data needed to set emissions criteria and to serve as a basis for assessing the potential hazard for asbestos pollution to the populace.
