This study was an attempt to understand how the available alternative source materials, such as oral testimonies can serve as valuable assets to unveiling certain aspects of maritime history in India. A number of themes in maritime history in India failed to get the attention of the generation of historians, because of the paucity of written documents. Unlike in Europe, the penning down of shipping activities was not a concern for the authorities at the port in India. The pamphlets and newsletters declared the scheduled departure of the ship in Europe but, in India, this was done verbally. Therefore, maritime history in India remained marginalised. Hence, in this article, I make an endeavour to perceive how the oral testimonies can help shed some new light on certain aspects of maritime history in India, such as life on the ship, maritime practices, and perceptions among the littoral people in coastal societies. This article also outlines an approach on how the broader question on the transformation of scattered maritime practices among coastal societies can be adapted and transferred into an organised institution of law by the nineteenth century, and how these can be pursued in future. I also suggest in this article that the role of Europeans, especially the British, in the process of transformation, can be investigated further through oral testimonies in corroboration with the colonial archival records.

This survey research based study sought determinants of biogas technology adoption in rural areas of Pakistan. Stratified random sampling technique was employed to select respondents because the population was unknown and heterogeneous in nature. Total 240 respondents (150 biogas users and 120 potential users) were selected and face to face interviewed using a structured, validated and pre-tested questionnaire. Along with descriptive analysis of data logistics regression model was applied to investigate the determinants of biogas adoption. Findings affirmed significant role of socio-economic characteristics  of respondents in the adoption of biogas technology. Empirical findings reported a significant impact of education, the income of households and the number of animals on the adoption of biogas technology. This implies that unit increase in education, income and number of animals will escalate the adoption of biogas technology. Tackling energy crisis, economic benefits, and production of slurry for soil fertility, health gains and environment-friendly nature of biogas were perceived reasons of biogas adoption among the biogas users. Non-government organizations and neighbours were leading motivational factors behind adoption as revealed by users. However, role of electronic media, print media and government institutionsin promoting biogas was reported dismal. This study urge that biogas is valuable alternative source of energy to combat energy crisis. In this way, provision of subsidies, interest free loans and technical backstopping could invoke potential users to adopt biogas technology.

‘Authorities’ considers how the rules of usage are established. It first describes the role of dictionaries, frequently held to be the ultimate authority. It then discusses linguistic academies, governing bodies that make pronouncements about correct usage. An alternative source to the dictionary is the usage guide, which tends to adopt a more prescriptive approach and which focuses on a small subset of frequently disputed points of usage. Other ways of determining acceptability is to turn to examples of actual usage, logic, or etymology. Despite the many controversies concerning correct usage and how it should be established, each of the authorities discussed would agree that there is a single authoritative form of the language, known as Standard English.

The literature related to the financial management acknowledges the significant role that political risk play to determine the financial market development. Further, financial system development (banking and financial markets) competes to provide long-term financing, and this competition might be positive or negative for each other. The aim of this paper is to propose a conceptual model/framework for investigating the role of political risk and financial market on Sukuk market development in Gulf Cooperation Council (GCC). GCC economies depend heavily on oil revenues which makes them subject to oil prices fluctuations. Therefore, GCC’s governments should diversify their economies by looking for Sukuk as an alternative source of financing, to cover their budget deficit, when the price of oil decreases, and reduce their reliance on oil, because Sukuk has advantages compared to the conventional bond particularly in terms of less information asymmetry. The prior studies have mostly focused on firms' characteristics determinants of Sukuk issuances but gave a little consideration to the role of country' characteristics on Sukuk market development. This paper proposes a framework to explain the political risk and financial markets determinants of Sukuk market development with a focus on the GCC countries that have the largest region in terms of the Islamic financial assets. It is anticipated that the outcome will support policymakers to improve the current state of Sukuk market.
