• Deriving the Meaning of Unknown Words From Multiple Contexts
  作者：Maartje van Daalen-Kapteijns、Marianne Elshout-Mohr、Kees de Glopper

  Students from 11 to 12 years old were invited to derive the meaning of five unknown words, each embedded in three contexts. We focused on the students' proficiency in three activities: decontextualization of the target word meanings from the contexts (decontextualization), testing initial ideas about the word meanings with subsequent contexts (cumulative testing), and formulating dictionary-like definitions

  邀请 11 至 12 岁的学生推导五个未知单词的含义，每个单词都嵌入三个上下文中。我们专注于学生在三项活动中的熟练程度：从上下文中去除目标词的含义（去上下文化），用后续上下文测试对单词含义的初步想法（累积测试），以及制定类似字典的定义（定义）。我们比较了八名语言能力高的学生和八名低语言能力的学生。学生们被单独引导，通过导出目​​标词的含义的过程，同时大声思考。研究表明，即使是语言能力低的年轻学生也能够进行意义推导活动，而这些活动通常归因于语言能力高的成熟学生。

• Effect of Poultry Litter Amendment on Hatchery Waste Composting

  Continuous growth of the poultry industry is accompanied by a need to manage large quantities of by-products such as hatchery wastes. Hatchery wastes contain nonfertile eggs, dead chicks, and broken eggshells. Although rendering plants currently use a portion of hatchery waste, large amounts are sent to landfills, which cost the poultry industry millions of dollars each year. As a potential alternative to landfilling, composting was investigated as a method to convert the nutrient rich waste into a stable product, for beneficial use.,Hatchery waste was. amended with sawdust and yard trimmings and in one treatment with poultry litter (broiler) to determine the feasibility of composting hatchery wastes. Hatchery waste co-composted with poultry litter maintained higher temperatures during,the experiment resulting in higher dry matter and volatile solids and greater losses of nitrogen by the end of the composting process. The composted product containing poultry litter had higher levels of plant nutrients such as P, K, and many of the other micronutrients than the product without poultry litter. Both treatments were effective in eliminating 99.99% of Escherichia coli; however, more Salmonella reduction was observed in the treatment containing poultry litter than the treatment without poultry titter.
