在大学英语教学过程中,对学生英语文化意识的培养应落实到词汇教学,课文讲解和新词追踪等教学环节。     

RFID技术在钢材质量追溯系统中的应用

文章首先简要介绍了无线射频识别RFID技术,探讨了现有的追溯方法在钢材质量管理中的局限性;然后．依据RFID的存储、跟踪、自动识别特性,在生产、运输、仓储、加工和使用等关键节点采集钢材质量属性信息,按操作顺序存储在RFID中;最后建立了一个贯穿于完整钢材供应链的质量安全控制体系,以支持从上游到下游的钢材质量追踪和从下游到上游的质量溯源。系统能有效实现钢材质量信息透明化管理,提升钢材使用工程质量。     

Eyes on the account size: Interactions between attention and budget in consumer choice

The context surrounding a consumer decision, such as one’s overall budget available for purchases, can exert a strong effect on the subjective value of a product. Across three eye-tracking studies, we explore the attentional processes through which budget size influences consumers’ purchasing behavior. Higher budgets increased and sped up purchasing even when items were affordable at all budget sizes. Moreover, attention interacted with budget size to promote purchasing at higher budgets. Finally, individual differences in the magnitude of the budget effect related to attentional patterns: those whose decisions depended more on budget exhibited more budget-price transitions and less variability in search patterns compared to those whose decisions were less dependent on budget. These findings indicate that attention moderates the effect of budgets on purchasing decisions, allowing low budgets to serve as self-control devices and large budgets to generate impulse purchases.
