This article uses Philadelphia Women Organized Against Rape (WOAR) as a case study to examine the intertwining of the feminist movement against sexual violence and state crime control agencies during the 1970s “war on crime.” Law Enforcement Assistant Administration (LEAA) officials expected the anti-rape organizers they subsidized to promote police reporting to the victims they served. This sharply contracted the terrain of feminist anti-rape activism, particularly for women of color who declined police reporting. Lynn Moncrief, a self-described “Black radical feminist” hired by Philadelphia WOAR using LEAA funds, rejected the mandate to increase police reporting rates. Instead, she devoted her energies to remaking WOAR's praxis with Black women and girls at the center. While LEAA funding tethered the anti-rape movement to the rapidly expanding carceral state of the late twentieth century, the example of Lynn Moncrief and the Third World Caucus of Philadelphia WOAR shows that cooptation was never total.

Linguistic magic can be divided into three major categories: the fiatic, the Orphic and the talismanic. The first category includes the creation of the signified by its signifier, the best example being the creation of the world by divine words. The Orphic category assumes the possibility of enchanting an already existing entity by means of vocal material. Last but not least is the talismanic, based on the drawing of energy by means of language, in order to use this energy for magical purposes. While the fiatic view assumes the complete superiority of the creator over the created object, the Orphic presupposes a certain similarity between the subject-magician and its object, whose role is to understand and follow the instructions of the magician. In these two categories meaning seems to be a crucial part of the magical linguistic activities. In the third category, the talismanic, linguistic powers are used in order summon higher powers which then descend to take possession of it. By talismanic I refer to the inherent ability of an entity, material, a moment in time, or a human act to draw upon these powers. Unlike amulets, which are usually taken to be objects that protect their possessor, the talisman is able to add power.

Municipal solid waste incinerator (MSWI) bottom ash is the slag-like material produced by the incineration of municipal waste and is predominantly composed of glassy constituents, which include inherited manufactured glasses and glasses formed during incineration. Previous results indicate evidence of neoformation of well-ordered clay (illite) from glasses in MSWI bottom ash after 12 y of natural weathering. We investigated the mechanism and conditions of clay formation from glasses during natural weathering using transmission electron microscopy (TEM), experimental leaching experiments and ammonium oxalate extractions. It was concluded that the high surface area and initially high “active” Al and associated Si content predispose the ash to form clay minerals on a relatively short time scale. This work provides evidence that the composition of secondary amorphous aluminosilicate and thus, the type of clay mineral which may form, is determined by the pH of the pore solution rather than by the glass composition. Presumably alternate wetting and drying of the ash during disposal greatly accelerates the formation of well-ordered clays.

X-ray phase analysis of clays is difficult because these materials generally consist of a mixture of different phases, i.e., mixed-layer minerals, individual clay minerals (non mixed-layer), and associated minerals, such as calcite and quartz. The analysis requires knowledge that presently is incorporated in a computer-based expert system. This expert system is capable of a) identification of associated minerals; b) identification of individual clay minerals; c) identification of the nature of the mixed-layer minerals; d) approximate structural characterization of the mixed-layer minerals; and e) precise structural determination of the mixed-layer minerals by comparison of experimental X-ray diffraction (XRD) patterns with calculated patterns for different models. Accuracy of the conclusions drawn by the expert system has been verified with literature data. Programs for the structural characterization of mixed-layer minerals must allow a) modification of the structural characteristics, abundances, and order-disorder distribution of the layers; b) modification of the distribution of the sizes of coherent scattering domains; and c) consideration of mixed-layer clays with more than two components. Two programs were written to calculate the XRD patterns of two- and three-component mixed-layer minerals consisting of any layer type and without any limitation in the order-disorder relationships.

Fine-grained biotite crystals within primary actinolite from a quartz monzonite body of the Bingham Canyon porphyry copper deposit, Utah, consist of 1M, 5M1, and 1Md polytype structures. HRTEM images directly show the stacking sequences of ordered biotite polytypes, stacking faults in ordered polytypes, and stacking sequences in disordered polytypes, if the stacking vectors for the 2:1 layers involve only 0° and ± 120° rotations. The most common type of stacking fault in the 1M biotite is a layer with −120° rotation, followed by a layer with +120° rotation, which corresponds to one unit cell of the 2M1 polytype inserted in the 1M structure. Disordered (or semi-random) biotite is composed primarily of thin domains of the 1M and 2M1 polytypes, with stacking faults. The structure of a new 5-layer (5M1) polytype has been determined from SAED and HRTEM results. The stacking sequence of the polytype is [02022].

A model of structural oscillation among 1M, 2M1, and 3T structural states is proposed to interpret nonperiodic stacking sequences in biotite crystals formed during non-equilibrium crystallization. The model also provides qualitative insights into the structure of complex long-period polytypes and may help to explain intergrowths of ordered and disordered polytypes that form during crystallization far from the equilibrium state.

Along the inner Coastal Plain, kaolinite-metahalloysite-rich, neritic muds of Cretaceous-Eocene age have undergone intense postdepositional alteration in the recharge area of the regional groundwater system. Weathering processes have had the following profound effects on the original sediments: 1) strong compositional and textural modification of both clay and non-clay minerals; 2) whitening of the originally darker sediments by partial removal of organic matter, Fe and Mn; and 3) recrystallization of kaolinite and metahalloysite, most conspicuous where there are coarse stacks and vermiforms. Where the combination of initial sediment composition and alteration intensity was most favorable, these changes have produced important deposits of commercial quality, which now sustain the world's largest kaolin production district. The earliest change was partial sequestration of iron as sulfide and concurrent destruction of some organic matter, mediated by sulfate-reducing bacteria. Subsequent weathering resulted in gradual leaching of alkalies, alkaline earths, iron and silica, and attendant nucleation and growth of minerals compatible with the compositional changes. The existence of several closely spaced erosional unconformities, separated by neritic sediments, is proof that weathering conditions commonly changed at a given site, in response to changes in thickness or lithology of the overlying rocks. Dsyoxic → ← oxic reversals modified both the rate and kind of alteration. (“Dysoxic” refers to molecular oxygen concentration too low to be toxic to anaerobes or cause abiotic oxidation; less extreme than “anoxic”.) Kaolins were produced partly by slower dysoxic weathering in saturated groundwater zones but mainly by more rapid oxic weathering in unsaturated zones, where bauxites also locally formed. Gradual transformation of some sediments to kaolin rarely began and ended in the same epoch. At several places most of the kaolinization (see “Definitions”) took place during Recent time, tens of millions of years after deposition of the sediments. Since the kaolins resulted from postdepositional alteration rather than sedimentary processes, they are better referred to as “Coastal Plain” rather than “sedimentary” kaolins.

Reading the vast panorama of the history of Western medicine in general and psychiatry in particular sheds an interesting light not only on social constructions and representations but also on the perception of the Other by the medical institution. Colonial medicine in its struggle - praiseworthy, moreover - against epidemics, presents an interesting case here. We read in the Colonial Medical Archives at Berlin, that a certain Dr Roesener was sent to Kamerun (Cameroon), a German protectorate, to take charge of the eradication of malaria, hookworm (anchylostoma), filariosa and sleeping sickness. But he also found himself faced with mental illnesses and, in his report of October 1909, reported the case of a sick man of the Dwala tribe claiming to be a friend of the Kaiser and presenting all the symptoms of mental illness. A problem of nosography arose - stemming from the cultural perception of an illness and above all of the Other: did this Dwala merit being mad? To understand the meaning of this question, we must return to the German anthropology of the last century, which made a clear distinction between ‘natural people’ (Naturmenschen) and those that were civilized, who were part of Kultur. Moreover, in this report Roesener used the word Naturmenschen to signify the Dwala. In this perspective, as the doctor notes, mental illness was, in the medical teaching of that time, a disturbance of the mind, a malaise of civilization. The prerequisite for being mentally ill was being implicitly part of a civilization. Mental illness was, moreover, translated in German by Geisteskrankheit, in other words, literally, illness of the mind. Now, the ‘natural person’ (the Dwala) has no civilization and in consequence cannot be sick in his mind. And yet he presented all the symptoms which made him a classic mental patient. Could one apply the nosography proper to illnesses stemming from civilization to ‘natural peoples’? Without resolving the problem which his terminological usage posed, Roesener insistently demanded that Berlin send the logistical means to Cameroon to build a lunatic asylum (Irrenhaus). To the problem of mental fragility that was posed came the answer of incarceration in a society that knew nothing of confinement of its ‘mental patients’, the latter often not being considered as inferior.

The clay mineralogy of tuffs from Yucca Mountain, Nevada, the potential site of the nation's first high-level radioactive waste repository, has been studied in order to understand the alteration history of the rocks and to predict potential future alterations. Bulk-rock samples and clay-mineral separates from three drill holes at Yucca Mountain (USW G-1, USW G-2, and USW GU-3/G-3) were studied using X-ray powder diffraction, and supporting temperature information was obtained using fluid inclusion data from calcite. Twelve K/Ar dates were obtained on illite/smectite (I/S) separated from the tuffs from the two northernmost drill holes, USW G-1 and G-2. The predominant clay minerals in the Yucca Mountain tuffs are interstratified I/S, with minor amounts of chlorite and interstratified chlorite/smectite. The I/S reactions observed as a function of depth are similar to those observed for pelitic rocks; I/S transforms from R = 0 interstratifications through R = 1 and R ≥ 3 interstratifications to illite in USW G-2 and to R ≥ 3 I/S in USW G-1. The R = 0 I/S clays in USW GU-3/G-3 have not significantly transformed. K/Ar dates for the I/S samples average 10.4 my. These data suggest that the rocks at depth in the northern portion of Yucca Mountain were altered 10.0-11 my ago, soon after creation of the Timber Mountain caldera to the north. Both I/S geothermometry and fluid inclusion data suggest that the rocks at depth in USW G-2 were subjected to postdepositional temperatures of at least 275°C, those in USW G-1 reached 200°C, and rocks from USW GU-3/G-3 probably did not exceed 100°C. These data suggest that no significant hydrothermal alteration has occurred since Timber Mountain time, ~ 10.7 my ago.

Estimates of the temperature of formation of illite/smectites yield probable stability limits for several minerals at Yucca Mountain. Clinoptilolite apparently became unstable at about 100°C, mordenite was not a major phase above 130°C, and analcime transformed to albite above 175°-200°C. It appears that cristobalite transformed to quartz at 90°-100°C in USW G-2 but must have reacted at considerably lower temperatures (and for longer times) in USW GU-3/G-3. The reactions with increasing depth appear coupled, and clinoptilolite and cristobalite disappear approximately simultaneously, supporting aqueous silica activity as a controlling variable in the clinoptilolite-to-analcime reaction. The reaction of clinoptilolite to analcime also coincides with the appearance of calcite, chlorite, and interstratified chlorite/smectite. Although the hydrothermal fluids may have been a source for some cations, breakdown of clinoptilolite (and mordenite) probably provided the source of some of the Ca for calcite, Mg for chlorite, K for the I/S found deeper in the section, and Na for analcime and albite.

Using the rocks in USW G-1, G-2, and GU/G-3 as natural analogs to repository-induced thermal alteration suggests that the bulk of the clinoptilolite- and mordenite-bearing rocks in Yucca Mountain will not react to less sorptive phases such as analcime over the required lifetime of the potential repository. The zeolites in zeolite interval I, directly underlying the proposed repository horizon, may transform at the predicted repository temperatures. However, the reaction of clinoptilolite to analcime in interval I may require the transformation of all of the abundant opal-CT and glass to quartz, an unlikely scenario considering the unsaturated nature of these rocks and the predicted temperatures of <100°C.

Israel is a country of many cultures and languages and of several religions. The majority of the population adheres to the Jewish religion. The Moslem and the Christian religions come next in size, in that order. Similarly to many other countries in the region, religion fills a more central role in the public sphere of Israel than in most Western countries. It also influences the private sphere immensely, as for example in the matter of marriages and funerals which in most cases are conducted by state employees who have been appointed by the religious establishments of each of the official religions. We are thus discussing religion in a context where it matters highly. Power, welfare and the very right to reside in the country are connected with religion. Symbols of statehood and collective identity are lent from religious texts, objects and rituals. The symbol of the state, the seven-armed golden candelabra, suggests the memory of the temples of Solomon and Herod where a similar one was standing.

A synergistic mechanism for the retention of organic and inorganic pollutants in clays is discussed in this paper. The mechanism of adsorption of cis- or trans- 1,2-dichloroethylene vapor (CDE or TDE, respectively) by hydrated smectite clay (hectorite) exchanged with Pb2+, Hg2+, Cd2+, Ca2+, Ag+, or Na+ has been investigated by simultaneously measuring chlorohydrocarbon uptake and water desorption isotherm and by recording the infrared (IR) spectrum of the adsorbed phase. Hydrated hectorite saturated with divalent cations adsorbs about 55% more CDE or 35% more TDE than those saturated with monovalent cations. The quantity of chlorohydrocarbon adsorbed is also a function of the hydration of the clay interlayer space. When dehydrated, hectorite does not adsorb CDE or TDE. Upon long outgassing at room temperature or even at 100°C, the characteristic IR bands of clays with adsorbed chlorohydrocarbon, although much weakened, are still observable. The ratio of the amount of water desorbed to the amount of chlorohydrocarbon adsorbed varied from about 0.22 to 0.34. A shift of the center of gravity of the hydration water OH stretching frequency towards a higher wavenumber and of the asymmetric CC1 stretching vibration toward a lower frequency suggest that the formation of hydrogen bonds between CDE or TDE and water is the driving force for adsorption and that the cation-dipole interaction does not play a major role.

This paper sets out to discuss the use and power of music in representing social identities, concentrating on the more specific case of the Brazilian nation, which has made itself a complex and all-embracing socio-political unit in spite of the great diversity and the great inequalities to be found within its borders. It is well known that what appears to be its most uniform feature, the use of a dominant language, is actually quite fragmented, due to the influence of various co-existing systems of production, cultural models and social hierarchies, which change on a daily basis. Although this diversity seems to be underwritten by daily practice and independent of debate and official encouragement, the same cannot be said of the search for national unity. It is obvious in the case of most of the action undertaken with this end in mind, that questions such as exclusion and the imbalance and arbitrariness of power have been eliminated. Besides, certain alert individuals are wary of this insistence on the construction of a nation, since the role of the old national states throughout the world seems to be disintegrating in the face of the proliferation and growing importance of social, economic and cultural relations at a supranational level. It is therefore hardly surprising that the twentieth century is considered to be a milestone in both the rise and fall of efforts to achieve Brazilian national unity. Amongst these efforts, music has played a prominent role, as I shall endeavour to show.

The rapid phase quantification method using X-ray diffraction (XRD) with a position-sensitive detector (PSD), outlined by Cressey and Schofield (1996), has been extended to facilitate mineral phase quantification of clay-bearing samples. In addition, correction factors for differences in matrix absorption effects have been calculated and applied. The method now enables mudrock mineralogy to be quantified rapidly and efficiently. Using this approach overcomes many of the problems hitherto associated with the quantitative analysis of clay minerals, in particular the effects of preferred orientation of crystallites and variable sample-area irradiation, that make the task of quantification extremely difficult by conventional Bragg-Brentano scanning diffractometry.

The Old Turkish inscriptions that were written roughly between the beginning of the eighth and the middle of the ninth century A.D. and represent the first testimonies of a Turkish language, include important information about contacts of the ruling Türks and later the Uighurs, who were also Turkish-speaking, with other peoples inside and outside of their el, i.e., their steppe empire. This information is partly explicit, when, for example, we read about a delegation being sent to the other side, and partly implicit, by which we mean outside influences that we can trace in the texts in different ways.

Chlorite and illite are commonly associated with ubiquitous secondary K-rich feldspar in the rocks located immediately above and below the Precambrian-Paleozoic unconformity in southwestern Ontario, and elsewhere in the mid-continent of North America. This alteration assemblage is attributed to long-distance migration of hot brines driven westward by orogenic processes originating along the eastern seaboard of North America. The δD and δ18O values of chlorite and illite, plus K-Ar dates for secondary K-rich feldspar and illite, were used to determine the nature, origin, and timing of the fluids that altered Precambrian granites and their overlying rocks in southwestern Ontario. The δ18O values of the chlorite-forming fluids are best explained by initial hot brines (≥50°C) evolved mostly from seawater. Secondary K-rich feldspar formation followed shortly thereafter, as the fluids cooled and perhaps mixed with meteoric water. Regional migration of the brines was induced by Taconic orogenic events to the east. The hydrogen and oxygen isotopic compositions for the secondary illite of the early to mid-Carboniferous indicate its crystallization from local meteoric water at low temperatures (40–55°C). Infiltration of local meteoric water into the Paleozoic and uppermost altered Precambrian rocks occurred during uplift, erosion, and subaerial exposure of local arches in southern Ontario. The local basement reactivation and associated secondary illite formation in this portion of the North American hinterland was likely a distal expression of east-coast Acadian and Alleghanian orogenic activity.

The adverse report of the Academy of Sciences, published in 1784, failed to put an end to the proselytism of Mesmer's early followers, nor did it scale down their ambitions to gain scientific recognition. The allure of mystery, the taste for wonders and the call of the unknown prevailed, and throughout that century numerous clashes occurred between the scientific establishment and those demanding its recognition. Their demand was founded not so much on a theoretical construct as on people's personal experiences as actors or witnesses, which were perceived to be true simply because they were nearly always profoundly disturbing. The fact is that, despite the observations of scientists such as Faraday, anyone could put questions to an ecstatic in a state of trance, have a medium summon the dead, or communicate with the “other world” by table-turning. Insofar as it rejected the validity of the most commonly accepted “research programmes”, the challenge to the institutions that were the guarantors of received knowledge was a major one.
