Spearheading Development Culture - A Case Study

The case study is about transforming the organizational culture of Green Field Group of Companies- an agro based business group. Within a small span of time, with the application of technology and scientific methods of land reclamation and use of appropriate agro-forestry cropping schedule, Green Field became quite a successful business venture. Although the founder and promoters of the business duly emphasized on technology related business processes, they overlooked the human organization of business, especially the majority of work force who belonged to the tribal community. Consequently, despite having achieved great success at the initial stage with the help of technology and the allied process, in the long run, the organization failed to deliver. Therefore, attempts were made to address the issues concerning the human resource of the organization. In this process, it was found there was an urgent need for change of human climate to usher in organizational development. With sincere Human Resource Development efforts, a climate of trust and faith could be developed. A sense of harmony prevailed among the work force irrespective of their background and position in the organisation. While undertaking this process, the organization of Green Field learnt to adopt new vision and corporate philosophy. Accordingly there was institutionalisation of people oriented practices which ultimately led to the growth of the organization.

Influence of fines content and initial shear stress on dynamic properties of hydraulic reclaimed soil

The hydraulic placement of sand fill is one of the most important methods of land reclamation. During the reclamation process, losses of fines in sand are induced by the transportation of soil which affects the dynamic properties of the soil materials. In this study, the reclaimed soil in the Yunlin area of Taiwan is adopted as the test material. Different fines contents, different relative densities, and initial stress ratio were taken as test conditions. Resonant column tests were performed to evaluate the shear modulus and damping ratio of the reclaimed soil under initial shear stress. The results show that the maximum shear modulus decreases as the fines content increases. The influences of initial shear stress are discussed. A prediction method for maximum shear modulus under different fines content and initial shear stress is proposed based on empirical equations obtained. The results can be helpful for land reclamation design and assessment.Key words: reclaimed soil, fines content, initial shear stress, dynamic properties.

The skim and burial plough: A new implement for reclamation of radioactively contaminated land

Radionuclides accidentally released to the atmosphere in severe nuclear accidents can give rise to widespread radioactive contamination of land. If no remedial action is taken, the contamination may constitute a long-term external radiation hazard. Similarly, agricultural and dairy produce from the contaminated land may be a source of internal radiation. A newly developed agricultural implement named the ‘kim and burial’ plough has been built and tested and shown to be an effective countermeasure against both of these potential hazards but without the disadvantages of some other land reclamation methods. The new plough skims off a shallow layer of the contaminated top soil and buries it at a depth of about 45 cm without inverting the 5–45 cm horizon. The results are that radiation levels at the soil surface are greatly reduced, the contamination becomes much less available for plant uptake and in most cases there is little or no effect on soil quality. The efficacy of the new plough has been demonstrated under particularly severe field conditions.
