Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.  相似文献

Although much is known about adults’ ability to orient by means of cognitive maps (mental representations of the environment), it is less clear when this important ability emerges in development. In the present study, 97 seven- to 10-year-olds and 26 adults played a video game designed to investigate the ability to orient using cognitive maps. The game required participants to reach target locations as quickly as possible, necessitating the identification and use of novel shortcuts. Seven- and 8-year-olds were less effective than older children and adults in using shortcuts. These findings provide clear evidence of a distinct developmental change around 9 years of age when children begin to proficiently orient and navigate using cognitive maps.  相似文献

It is widely accepted that assessment plays a role in monitoring the development of young children with special needs in early intervention/early childhood settings. The process of assessing young children's language skills often looks for delays within a solid language foundation. However, many children who are deaf or hard of hearing (DHH) may not have a solid language foundation to assess, leading to inaccurate assessment. When we reframe how we assess language skills in children who are DHH, we ensure the assessment provides a comprehensive picture of the child's language development. It is important to modify language assessment tools where necessary while ensuring the assessment stays reliable and valid. It is critical to use multiple assessment tools to monitor the child's progress, including standardized assessments and assessment tools normed for DHH populations. Finally, it is crucial to monitor the child's skills in each language that they are using, regardless of which language is used most often. We explain why each of these factors needs to be considered in the assessment of young children who are DHH, will discuss the challenges of assessing this population, and will provide solutions to some of the challenges of assessing language skills in of young children who are DHH.  相似文献

In this essay, Polly Graham addresses a current instantiation of what might be called self‐loss within education in the United States. Graham observes that, in her experience, many students and educators, whether decidedly or without reflection, conform to superficial schooling practices that circumscribe the possibility of receiving affirmations for the sense of self we implicitly know to be authentic. Through narrative, she puts forward the possibility of “educational love” as a counter to the fundamental insecurity associated with habits of acting in conformance with superficial, alienated, school‐determined identity criteria. The question of “repetition” in a Kierkegaardian sense invites the reader to resist the logic of standardization — which assumes and valorizes comparability and reliability from an outsider perspective — in favor of a consideration of generalizability as embedded within the intimacy of a particular relation. As such, educational love is resonance rather than dictation.  相似文献

Handwriting is still a prominent mode for composing for both children and adults As a result, it is important that developing writers acquire fluent and legible handwriting. This article examines the five investigations that were presented in this special issue on handwriting instruction, providing a summary of their collective contributions as well as the limitations of each paper.  相似文献

Athletes need excellent vision to perform well in their sports, and many athletes have turned to vision training programs as a way to augment their traditional training regimen. The growing practice of ‘sports vision training’ relies on the notion that practice with demanding visual perceptual, cognitive, or oculomotor tasks can improve the ability to process and respond to what is seen, thereby improving sport performance. This enterprise is not necessarily new, but has been advanced greatly in the past few years by new digital technology that can be deployed during natural training activities, by perceptual-learning-inspired training programs, and by virtual reality simulations that can recreate and augment sporting contexts to promote certain sports-specific visual and cognitive abilities. These improved abilities may, in turn, instill a competitive advantage on the playing field, underscoring the potential value of these approaches. This article reviews emerging approaches, technologies and trends in sports vision training. Where available, critical review of supporting research is provided.  相似文献
