Algae have been used since ancient times as food, fodder, fertilizer and as source of medicine. Nowadays seaweeds represent an unlimited source of the raw materials used in pharmaceutical, food industries, medicine and cosmetics. They are nutritionally valuable as fresh or dried vegetables, or as ingredients in a wide variety of prepared foods. In particular, seaweeds contain significant quantities of protein, lipids, minerals and vitamins. There is limited information about the role of algae and algal metabolites in medicine. Only a few taxa have been studied for their use in medicine. Many traditional cultures report curative powers from selected alga, in particular tropical and subtropica...
This book is intended to construct a basis for the understanding of the rites and practices associated with exorcism, or jinn eviction as it is performed within the maraboutic institution called zawiya. Jinn eviction as it occurs in the maraboutic institution reproduces ideologies and social hierarchies of traditional society through the use of a variety of healing symbols and rituals. These symbols are delved into for the benefit of understanding the perennial cultural foundations of the discourse and practice of power in Morocco. The result is an ethnography of possession that has combined meticulous ethnographic field work with critical discourse analysis.

Thin capitalization rules (TCRs) aim to mitigate profit shifting by multinational corporations (MNCs) but, by raising the cost of capital for affected affiliates, can also negatively affect real investment. Exploiting unique panel data on multinational companies in 34 countries during 2006-2014, we estimate that the size of this adverse investment effect can be large, and dependent on the statutory corporate tax rate and the tightness of the safe-haven ratio. Negative investment effects are more pronounced for highly-levered firms for which TCRs are more likely to be binding.
Using administrative tax records for UK businesses, we document both bunching in annual turnover below the VAT registration threshold and persistent voluntary registration by almost half of the firms below the threshold. We develop a conceptual framework that can simultaneously explain these two apparently conflicting facts. The framework also predicts that higher intermediate input shares, lower product-market competition and a lower share of business to consumer (B2C) sales lead to voluntary registration. The predictions are exactly the opposite for bunching. We test the theory using linked VAT and corporation tax records from 2004-2014, finding empirical support for these predictions.
Developing countries apply numerous sector-specific taxes to telecommunications, whose buoyant revenues and formal enterprises provide a convenient “tax handle”. This paper explores whether there is an economic rationale for sector-specific taxes on telecommunications and, if so, what form they should take to balance the competing goals of promoting connectivity and mobilizing revenues. A survey of the literature finds that limited telecoms competition likely creates rents that could efficiently be taxed. We propose a “pecking order” of sector-specific taxes that could be levied in addition to standard income and value-added taxes, based on capturing rents and minimizing distortions. Taxes that target possible economic rents or profits are preferable, but their administrative challenges may necessitate reliance on service excises at the cost of higher consumer prices and lower connectivity. Taxes on capital inputs and consumer access, which distort production and restrict network access, should be avoided; so should tax incentives, which are not needed to attract foreign capital to tap a local market.
