Women, Possession Trance Cults, and the Extended Nutrient‐Deficiency Hypothesis
(1977) has shown more clearly than I did, in Egypt and elsewhere where it occurs this cult is often associated with the embourgoisement of men and women--involving a curtailment of the latter's freedom (see also Ferchiou 1972:66; Lewis, forthcoming). Finally, while I have no quarrel with Kehoe and Giletti's characterization of my interpretation of possession cults as "political," I have never advocated a monocausal explanation of such protean phenomena. By the same token and contrary to their assertions, I have explicitly pointed out (Lewis 1966:325) that in this context the concepts "center" and "periphery" are relative and ambiguous. If authors choose to recycle the reductionist "explanations" of Marvin Harris and his school, they might at least take the trouble to get their facts right.
Women's Preponderance in Possession Cults: The Calcium-Deficiency Hypothesis Extended
The preponderance of women in spirit possession cults is linked with the likelihood of deficiencies in thiamine, tryptophan-niacin, calcium, and vitamin D in women in Old World traditional societies in which poverty and/or sumptuary rules restrict women's nutrient intakes more than those of men. The higher nutrient needs of pregnant and lactating women may exacerbate the inadequacy of their diets. It is postulated that involuntary symptoms of deficiencies affecting the central nervous system and muscles have been recognized in these societies as manifestations of spirit possession and institutionalized as a means of reducing victims' anxieties and restoring their ability to function normally
Analysis of Macro and Micronutrients in Soils from Palestine Using Ion Exchange Membrane Technology
Ion Exchange membrane technology (IEM) is a method that allowed a single extraction process and a single subsequent measurement of different elements that are available in soil. The values of the available forms of the different macro- and micronutrients obtained by IEM extraction were compared with the values of the soluble form obtained by conventional extraction methods. In surface soil sample, the concentrations of available potassium, nitrate, phosphate, iron and boron were 37.7 mg kg–1, 17.5 mg kg–1, 3.6 mg kg–1, 171.0 μg kg–1, and 4.2 μg kg–1 respectively were greater than that of soluble forms of the same elements which were 7.0 mg kg–1, 9.2 mg kg–1, 0.4 mg kg–1, 109.0 μg kg–1, and 1.9 μg kg–1 respectively.
