God’s Draaimolen

Het Midden-Oosten kent een lange geschiedenis van religieuze pluriformiteit. Zowel binnen de islam als daarbuiten bestaat er al eeuwenlang veel opvallend variatie in geloof en ritueel. De geschiedenis van het Midden-Oosten toont aan dat monotheïsme niet noodzakelijkerwijze leidt tot uniformiteit en intolerantie. Tegenwoordig staat de religieuze diversiteit in het Midden-Oosten echter onder sterke druk. Deze tekst gaat vooral over de historische omgeving die religieuze pluriformiteit in het Midden-Oosten mogelijk maakte. De rode draad in dit verhaal is het spanningsveld tussen gewenste eenheid en voortgaande pluriformiteit alsook de religieuze reflectie over wat eenheid is en wat daarvan de consequenties voor de samenleving zijn

An immunoassay for the measurement of (1→3)-β-D-glucans in the indoor environment

An inhibition enzyme immunoassay was developed for quantitation of (1→3)-β-D-glucans in the indoor environment. Immunospecific rabbit antibodies were produced by immunization with bovine serum albuminconjugated laminarin.The laminarin calibration curve ranged from 40 to 3000 ng/ml.Another (1→3)-β-D-glucan (curdlan) showed a similar inhibition curve, but was less reactive on a weight basis. Pustulan, presumed to be (1→3)-β-D-glucan, also showed immunoreactivity in the assay. Control experiments indicated that this was due to (1→3)-β-D-glucan structures. Other non-(1→3)-β-D-glucan polysaccharides did not react. (1→3)-β-Dglucan was detectable in dust from a variety of occupational and environmental settings. We conclude that the new assay offers a useful method for indoor (1→3)-β-Dglucan exposure assessment

Health Effects of Airborne Exposures from Concentrated Animal Feeding Operations

Toxic gases, vapors, and particles are emitted from concentrated animal feeding operations (CAFOs) into the general environment. These include ammonia, hydrogen sulfide, carbon dioxide, malodorous vapors, and particles contaminated with a wide range of microorganisms. Little is known about the health risks of exposure to these agents for people living in the surrounding areas. Malodor is one of the predominant concerns, and there is evidence that psychophysiologic changes may occur as a result of exposure to malodorous compounds. There is a paucity of data regarding community adverse health effects related to low-level gas and particulate emissions. Most information comes from studies among workers in CAFO installations. Research over the last decades has shown that microbial exposures, especially endotoxin exposure, are related to deleterious respiratory health effects, of which cross-shift lung function decline and accelerated decline over time are the most pronounced effects. Studies in naïve subjects and workers have shown respiratory inflammatory responses related to the microbial load. This working group, which was part of the Conference on Environmental Health Impacts of Concentrated Animal Feeding Operations: Anticipating Hazards—Searching for Solutions, concluded that there is a great need to evaluate health effects from exposures to the toxic gases, vapors, and particles emitted into the general environment by CAFOs. Research should focus not only on nuisance and odors but also on potential health effects from microbial exposures, concentrating on susceptible subgroups, especially asthmatic children and the elderly, since these exposures have been shown to be related to respiratory health effects among workers in CAFOs

IARC Monographs: 40 Years of Evaluating Carcinogenic Hazards to Humans

Background: Recently, the International Agency for Research on Cancer (IARC) Programme for the Evaluation of Carcinogenic Risks to Humans has been criticized for several of its evaluations, and also for the approach used to perform these evaluations. Some critics have claimed that failures of IARC Working Groups to recognize study weaknesses and biases of Working Group members have led to inappropriate classification of a number of agents as carcinogenic to humans. Objectives: The authors of this Commentary are scientists from various disciplines relevant to the identification and hazard evaluation of human carcinogens. We examined criticisms of the IARC classification process to determine the validity of these concerns. Here, we present the results of that examination, review the history of IARC evaluations, and describe how the IARC evaluations are performed. Discussion: We concluded that these recent criticisms are unconvincing. The procedures employed by IARC to assemble Working Groups of scientists from the various disciplines and the techniques followed to review the literature and perform hazard assessment of various agents provide a balanced evaluation and an appropriate indication of the weight of the evidence. Some disagreement by individual scientists to some evaluations is not evidence of process failure. The review process has been modified over time and will undoubtedly be altered in the future to improve the process. Any process can in theory be improved, and we would support continued review and improvement of the IARC processes. This does not mean, however, that the current procedures are flawed. Conclusions: The IARC Monographs have made, and continue to make, major contributions to the scientific underpinning for societal actions to improve the public’s health

A Wedding Gone Wrong The Rather Worldly Woes of a Rather Wealthy Qādirī Sufi Shaykh. Two 18th Century Documents from the Ottoman Court Records of Ḥamā and Aleppo

A rather intricate legal case took place first in Ḥamā’s and then in Aleppo’s Ottoman Islamic courts around the middle of the 18th century. The setting, the social standing of the individuals involved, and the alleged circumstances of the case all contribute to make clear that this was not just another routine court case. Altogether, the two documents are a good example of the scope and quality of the information preserved in the archives of local courts and they both demonstrate the extent and modes of implementation of Islamic law in a specific Ottoman milieu. The long inventory of personal property in the Aleppo document gives us a good idea of the social status and affluence enjoyed by the plaintiff – a member of the Jīlānī/Qādirī family - and an interesting insight into material culture and what constituted wealth and affluence at the time.
