Influence ofAmaranthus hybridus L. allelochemics on oviposition behavior ofSpodoptera exigua andS. eridania (Lepidoptera: Noctuidae)

Common pigweed,Amaranthus hybridus L., is a favorite host of the beet army worm (BAW),Spodoptera exigua L. Chemicals extracted from homogenized pigweed with distilled water, ethanol, or dichloromethane and sprayed back on pigweed deterred oviposition by the BAW. Similarly, water extracts of frass from conspecific larvae or southern armyworm (SAW) larvae,S. eridania (Cramer), fed pigweed leaves and sprayed back on pigweed plants also deterred BAW oviposition, thus confirming that deterrence was due to plant allelochemics rather than specific compounds associated with the metabolic or excretory products of the larvae. Confirmation of the presence of oviposition-deterring chemicals in pigweed was used to explain a previously observed seasonal displacement of BAW by SAW on pigweed in the field.Mention of a commercial or proprietary product does not constitute an endorsement by the USDA.     

东营凹陷南斜坡储集层成岩作用及对储集性能的影响

东营凹陷南斜坡孔店组岩石类型以岩屑长石砂岩为主 ,长石砂岩和岩屑砂岩次之 ,其中岩屑长石砂岩含量超过 90 %。砂岩成岩作用包括压实作用、胶结作用、溶蚀作用、交代作用等 ,其中胶结作用使储层原生孔隙迅速变差 ,而溶蚀作用是次生空隙发育的主要因素。孔店组砂岩成岩作用进入晚成岩A期 ,期间经历了早成岩A期、B期。影响成岩作用的主要因素为构造演化背景、岩石成分、沉积环境、孔隙流体性质等。

Insult, aggression, and the southern culture of honor: An "experimental ethnography."

Three experiments examined how norms characteristic of a "culture of honor" manifest themselves in the cognitions, emotions, behaviors, and physiological reactions of southern White males. Participants were University of Michigan students who grew up in the North or South. In 3 experiments, they were insulted by a confederate who bumped into the participant and called him an "asshole." Compared with northerners (who were relatively unaffected by the insult) southerners were more likely to think their masculine reputation was threatened, more upset (as shown by a rise in cortisol levels), more physiologically primed for aggression (as shown by a rise in testosterone levels), more cognitively primed for aggression, and more likely to engage in aggressive and dominant behavior. Findings highlight the insult–aggression cycle in cultures of honor, in which insults diminish a man's reputation and he tries to restore his status by aggressive or violent behavior.

夏邑县火店南煤勘查区二2煤层煤质评价

夏邑县火店南煤勘查区位于夏邑县城东南25 km。通过对主要可采煤层二₂煤各指标的定量分析表明，勘查区二₂煤属半亮型煤，低灰、低挥发分、特低硫、较高软化温度灰和较高流动温度灰、特高热值的无烟煤三号和贫煤。贫煤可作气化、动力和民用煤；无烟煤除可作动力和民用外，块煤可作化工原料，经过一定加工，粉状煤可供高炉喷吹燃料。     

Comparative analysis of public participation in the EIA process for Thai overseas investment projects: Krabi coal terminal,Hongsa coal power plant,and Dawei special economic zone

While Thai overseas investment projects (TOIPs) have become a key form of development in the region, their environmental impact assessment (EIA) quality has been criticized. This research sought to analyze the differences in EIA practices in terms of public participation (PP) in two TOIPs – the Hongsa coal-fired power plant (Lao PDR) and the Dawei special economic zone (Myanmar) – versus a national-level project, the Krabi coal terminal. For Laos and Myanmar, which did not previously require PP, the Thai consultants did not apply the Thai PP framework, leading to poor public participation index (PPI) scores = 0.02, indicating a negligible PP process. However, the consultant on the Krabi coal terminal claimed to abide by the Thai regulations, yet the PPI scores claimed = 0.81 (substantive rationale), were quite different from those indicated by the affected villagers = 0.39 (instrumental rationale). These villagers’ concerns resulted in conflict between the affected villagers and project owners. Our findings have revealed the true necessity of PP regulation and systems to monitor consultant performance to ensure sustainability of TOIPs in neighboring countries.
