This could be attributed to the fact that the activities of Oil TNCs have continued to unleash untold devastation on the environment of the oil producing communities and its consequences on the local economy and by extension the total obliteration of the livelihood of the inhabitants of the area. Therefore, the Oil TNCs are increasingly becoming conscious of their devastating impact on the ecology of the area and their blatant disregard for the socio-economic development of the host communities. Consequently, the Oil TNCs have come to embrace the idea of executing Corporate Social Responsibility （CSR） projects as a vehicle to intervene meaningfully in order to mitigate the adverse effect of their operations in host communities. This paper attempts a review and analysis of CSR practices of the two major Oil TNCs in Bayelsa State： Shell and Agip in six host communities： Olugboboro, Olugbobiri, Ikebiri 1, Oporoma, Angiama, and Peremabiri in Southern ljaw local government area. The key question explored in this study is： Has the practice of CSR in the Nigerian Niger Delta region by Oil TNCs brought about socio-economic development and drastic reduction in conflict between the host communities and the Oil TNCs？ The paper argues that CSR projects of transnational oil corporations in Nigeria are driven by short-term expediency rather than the long term development needs of host communities through the provision of poor quality social amenities to these communities in order to secure social license to operate. For transnational oil corporations to make positive impact in the Nigerian Niger Delta Region, their CSR projects should be long tern in nature, taking into consideration the sustainable development needs of the local communities. The CSR projects should be in the form of high quality social amenities and environmental rehabilitation and protection, which could serve the needs of the present and future generations.展开更多

To control agricultural pollution effectively,it is needed to implement integration of agricultural and environmental policies,establish environmentally friendly agricultural technology popularizing system,implement integrated planning and management of a basin,and set up and improve legislation to protect agricultural environment.展开更多

When we include special relativity expressed in simplest units, we find that, for particulate matter, the square of rest mass , i.e., angular frequency squared minus wave vector squared. This equation separates into a conservative part and a uniform responsive part. A wave function is derived in manifold rank 4, and from it are derived uncertainties and internal motion. The function solves four anomalies in quantum physics: the point particle with prescribed uncertainties;spooky action at a distance;time dependence that is consistent with the uncertainties;and resonant reduction of the wave packet by localization during measurement. A comparison between contradictory mathematical and physical theories leads to similar empirical conclusions because probability amplitudes express hidden variables. The comparison supplies orthodox postulates that are compared to physical principles that formalize the difference. The method is verified by dual harmonics found in quantized quasi-Bloch waves, where the quantum is physical;not axiomatic.展开更多

At a psychiatric hospital, occupational therapists (OT) made patients with dementia perform vegetable harvesting activities as a part of their treatment. The patients became calmer and began to smile not only after but also before and during harvesting activity. Therefore, this study aimed to measure autonomic nervous system (ANS) responses over time in a female patient in her 80s with moderate Alzheimer’s disease (AD) who had experience in farming when performing harvesting activities. Additionally, this study aimed to consider factors associated with changes in ANS responses over time and to verify the physiological therapeutic effects of harvesting activities. Methods: An OT with more than 10 years of experience and a good relationship with the patient conducted one-on-one sessions with the patient. Harvesting activity was performed in a courtyard with trees. The patient harvested lettuce (three lettuce plants) grown in a planter while sitting on a chair. Additionally, the planter was set up on a desk. ANS responses were measured over time from before to after the activity for different events at six time periods. Changes in the patient’s ANS responses were assessed during each period. Results: With the involvement of environmental factors and OT during harvesting activities, parasympathetic nervous system (PNS) activity significantly increased. This may lead to improved mental stability. Conclusion: The findings of this study indicate that implementing harvesting activities may have a positive effect on the PNS in patients with AD with long-term agricultural experience. However, further studies with a larger sample size and multidimensional evaluations are needed.展开更多
