Int.oduct.on: Pest.cides are current.y an essent.al component.of agricult.ral product.on t.chniques for cont.olling pest. and weeds. In Burkina Faso, non-compliance wit. good pract.ce in t.e use of pest.cides poses a real healt. problem for t.e populat.on. t.is st.dy examines t.e healt. risks associat.d wit. pest.cide management.in rice-growing areas. Mat.rial and Met.ods: A field survey was conduct.d in Bama, involving farmers, focusing on t.eir socio-demographic charact.rist.cs, pest.cide usage, and healt. effect.. Cholinest.rase levels were measured in subsample of farmers using a port.ble device. Dat. were analysed using Microsoft.Excel, calculat.ng means and percent.ges for various pract.ces. Healt. consult.t.ons, prot.ct.on met.ods, and pest.cide management.were st.died. Eryt.rocyt. acet.lcholinest.rase act.vit. was compared before and aft.r t.eat.ent. Dat. were cat.gorised int. classes based on inhibit.on levels, and correlat.on analyses det.rmined relat.onships bet.een variables such as age, years of experience, and cholinest.rase act.vit.. Result.: t.e result. indicat. t.at.rice cult.vat.on is mainly carried out.by a fairly young populat.on, wit. nearly 63% being under t.e age of 50. Common poor pract.ces in pest.cide use include improper st.rage and reuse of left.ver pest.cides. Seven t.pes of pest.cides were ident.fied, including organophosphat.s such as glyphosat., which was used in 26.7% of cases. t.is organophosphat. has result.d in class B poisoning, causing a 30% - 50% reduct.on in eryt.rocyt. cholinest.rase act.vit.. t.e healt. effect. of pest.cide use are felt.by agricult.ral farmers t.rough various sympt.ms of poisoning. Conclusion: t. reduce t.e occurrence of pest.cide poisoning, it.is essent.al t. launch informat.on and awareness campaigns among t.e populat.on and farmers t. promot. safe pract.ces in pest.cide use in Bama, Burkina Faso.

埃拉从不喜欢午睡。当她还是个婴儿时,她会整个下午呆在卧室外面玩玩具。她的母亲告诉她,无论她房间的窗帘有多暗多厚,埃拉都只在外面天黑的时候才会睡觉。在埃拉小学二年级的时候,她已经不记得上次午睡是什么时候了。埃拉晚上睡得很好,但她认为午睡是婴儿和病人才会做的事。但即使埃拉生病了,她也不睡午觉,而是躺在床上看书。

当代西方新唯物主义的共识在于质疑人类中心主义预设,并要求恢复物质自身的活力。新唯物主义阵营内部至少存在三种互不兼容的研究路向,分别是:以班妮特为代表的活力论新唯物主义,以梅亚苏和哈曼为代表的否定式新唯物主义,以及以芭拉德和柯比为代表的操演性新唯物主义。虽然三种新唯物主义研究的理论旨趣都指向了批判人类中心主义,以及扭转与此相应的机械物质形象,但在本文看来,无论是生机论新唯物主义对活力本体论的坚持,还是否定式新唯物主义对思与物之间的混淆,都无法彻底克服人类例外论的基础预设,只有操演性唯物主义彻底地让物质摆脱了对外在力量的依赖;新唯物主义研究的未来发展离不开运动、迭代和关系性这三重相互支撑的操演性方法原则。
