Impact of Environmental Regulation in a Small Open Economy

Abstract: The paper attempts to examine the impact of change in government regulation about environmental standard on the level of environmental pollution and on the level of social welfare as well as real national income in the developing economy where the manufacturing sector is unable to maintain their pollution level upto maximum permissible level of pollution imposed by the environmental authority. A fine for violation of environmental standard is imposed on the producer of the manufacturing sector. The study also shows that under some reasonable conditions there arises a favourable impact on the level of overall environmental pollution and on the level of social welfare as well as real national income due to relatively stringent government regulation about environmental standard.

Behaviour of a square footing on reinforced soil: an experimental study

Abstract: Several investigations are reported in literature pertaining to the numerical and experimental studies on the behaviour of footings subjected to vertical loads on un- reinforced soil and the reinforced. Several works reported in the literature deal with the use of waste materials in various civil engineering works to enhance certain soil characteristics. Hardly any literature is found on reinforced soil technique using rubbergrids as a reinforcing material for foundation on soft clays. In view of this, experimental investigations are reported on the study of load-deformation behavior of a model square footing on reinforced soil in respect of a two-layered system consisting of clay as sub-grade and mine waste as backfill material. The footing was subjected to axial load. Two different types of reinforcing materials such as Kolon Geogrid (KGR-40) and rubber grids derived out of waste tyres were used in the study. The study revealed appreciable increase in ultimate bearing pressure and decrease in settlement with the provision of single layer reinforcement. Further, rubbergrid performed better than the Geogrid in respect of BCR and SRF. The study underscores significance of solid waste materials such as mine wastes and discarded tyres as effective civil engineering construction materials.

Fragmentation, skill formation and international capital mobility

Abstract: During the last few decades an important feature of the on-going process of globalization is production fragmentation. Owing to the growing importance of international fragmentation of production p...

International Fragmentation in the Presence of Alternative Health Sector Scenario: A Theoretical Analysis

Abstract: This paper attempts to integrate among international fragmentation, trade liberalization and health sector. For this purpose we have considered two different models based on Heckscher-Ohlin-Samuelson general equilibrium structure, with special reference to the health sector. In the first model we have considered four sectors and we have assumed the production process of the health sector can be fragmented. In such a set up we have shown that a movement from a regime of no fragmentation to a regime of fragmentation may lead to an expansion of the health sector. In the second model we have considered three sectors and have assumed that production process of the health sector is fragmented. In that structure we have shown that trade liberalization leads to an increase in the output level of the health sector.

Economic Liberalization and urban unemployment in the presence of informal sector

Abstract: In this paper, we construct a three sector general equilibrium model of a small open economy with informal sector. The paper examines the impact of less protectionist policy on the output levels, factor prices, and the level of urban employment. Here, it has been shown that the urban unemployment rate has been lowered with the contraction of import competing manufacturing sector consequent upon a reduction in tariff. The informal intermediate sector has contracted as well. It is further shown here that there is a possibility of expansion of exportable agricultural sector with increased wage rate. The paper is then extended to introduce foreign capital inflow and examine on the output effects and the level of unemployment. Interestingly, in the extended model urban unemployment is aggravated due to an inflow of foreign capital.

Electrophilicity index within a conceptual DFT framework

Abstract: Conceptual density functional theory provides a method for analyzing the chemical reactivity in terms of different global reactivity descriptors including electrophilicity and their local counterparts like philicity. These concepts’ definitions and various applications that demonstrate their interpretive power are discussed. Global and local electrophilicities are able to account for a wide variety of chemical phenomena.

Impacts of shrimp farming on the coastal environment of Bangladesh and approach for management

Abstract: The frozen food export sector, next to readymade garments sector, is the second largest export earner of Bangladesh. Shrimp, main item of frozen food, is a major contributor in the national economy of Bangladesh since mid 1980s. Although it provides millions of employment and earns more than US$ 445 million annually, it has been facing a host of challenges. Shrimp farming has been associated with a number of negative environmental and social impacts which hinder the sustainable development of this blooming sector. This paper aim to focus on how the shrimp culture in Bangladesh is affecting the adjacent environment as well as society and management approach for it’s sustain ability by means of reviewing the available scientific literatures. It finds the grave socioeconomic impacts including traditional livelihood displacement, loss of land security, food insecurity, marginalization, rural unemployment, social unrest and conflicts in the wake of shrimp culture development in Bangladesh. Similarly, environmental impacts such as mangrove degradation, loss of biodiversity, sedimentation, saltwater intrusion, and pollution and disease outbreaks are found to be the main obstacles for the development of sustainable shrimp farming. Inappropriate management practices and inadequate plans regarding water quality, seed supply, irrigation facilities and fishery resources are the main reasons for these impacts of shrimp farming. The effective management measures to mitigate the adverse environmental impact of shrimp farming development have now become urgent requirement.

Prediction of the fate of organic compounds in the environment from their molecular properties: a review.

Abstract: A comprehensive review of quantitative structure-activity relationships (QSAR) allowing the prediction of the fate of organic compounds in the environment from their molecular properties was done. The considered processes were water dissolution, dissociation, volatilization, retention on soils and sediments (mainly adsorption and desorption), degradation (biotic and abiotic), and absorption by plants. A total of 790 equations involving 686 structural molecular descriptors are reported to estimate 90 environmental parameters related to these processes. A significant number of equations was found for dissociation process (pKa), water dissolution or hydrophobic behavior (especially through the KOW parameter), adsorption to soils and biodegradation. A lack of QSAR was observed to estimate desorption or potential of transfer to water. Among the 686 molecular descriptors, five were found to be dominant in the 790 collected equations and the most generic ones: four quantum-chemical descriptors, the energy of the...
