The problem of observing the state of a linear finite dimensional system in the presence of unknown disturbance noise is considered. Necessary and sufficient conditions are developed for the existence of a minimal order observer capable of producing an asymptotic estimate of the state of the given system. The approach used leads to a computationally attractive procedure for obtaining an observer having specified eigenvalues. 相似文献

A model is presented regarding associations between economic strain, support from spouse, and quality of parenting. The model was tested using a sample of 451 2-parent families, each of which included a seventh grader (age 12-13). Parent and adolescent reports, as well as observational ratings, were used as indicators of constructs. Analysis using structural equation modeling procedures indicated that level of spouse support was positively related to supportive parenting, whereas economic strain operated to undermine parental involvement. As posited, economic strain produced its effect through a direct relation with parenting and indirectly through its association with spouse support. These findings held for mothers and fathers, regardless of the gender of the child. Spouse support moderated the impact of economic strain on supportive parenting for mothers but not fathers. Possible explanations for this gender difference are presented. 相似文献

To investigate how source of event information influences children's event representations, 5- and 6-year-old children were exposed to a novel event through direct experience, observation, or a story. 2 of the 4 scenes comprising the event contained actions that were logically organized, and the remaining 2 scenes contained actions that were arbitrary in their organization. Children received either 1 or 3 exposures to the event. For children receiving multiple exposures, 2 scenes contained actions that varied across exposures. A few days following their last exposure, children were asked to verbally recall and reenact the event. Reports were generally more complete, organized, and accurate when the event was directly experienced compared to when it was observed or heard about through a story. However, the impact of information source interacted with interview (recall, reenactment) and number of event exposures. Furthermore, children's sensitivity to event structure was dependent on information source and exposure. These results highlight the importance of information source in the formation of children's event representations. 相似文献

Mordechai Gordon 《Educational theory》2007,57(1):37-52
A bstract . In this essay, Mordechai Gordon explores the significance of Rilke's challenge to "live the questions" and embrace uncertainty with respect to the quest for certainty in education. The quest for certainty in education refers to our desire to gain a sense of psychological security and more control over a field that is fundamentally indeterminate. This quest implies an unwillingness to live with the inherent complexities and risks of education. After exploring the meaning and import of Rilke's challenge and comparing it to the position of Socrates, Gordon uses Rilke's insight to analyze a specific educational experience and then discusses some of its educational implications for teacher education. 相似文献

Recent research has highlighted the complexity of the battered child syndrome. Clinical experience suggests that treatment of troubled families is a long-term process, draining financial resources of agencies and emotional resources of professionals. The need to provide support and case consultation to professionals working in the area of child abuse and neglect evolved in the establishment, in 1968, of the Suspected Child Abuse and Neglect (SCAN) Program at Children's Hospital, Pittsburgh, Pennsylvania. This program provides an effective method of intervention through identification, consultation, referral and follow-up of at-risk families. Weekly meetings offer multi-disciplinary case coordination, treatment recommendations, and a channel of communication for representatives of community agencies. This paper traces the history and present status of the SCAN Program, as well as the role of SCAN as a force for change of community attitudes. 相似文献

Within the field of intellectual disability, progressive policy thinking in Wales has led to an emphasis on the tailoring of services to individual needs and wants of service users, especially through individual planning processes and the creation of service packages. Using an adapted structure‐process‐outcome evaluation model, research is reported about how informal supporters appraise service quality. Based on a survey of 752 families, the first phase of the research reported here has been concerned with charting relationships between personal characteristics of users, service process factors and appraisals by informal supporters of service quality. The findings suggest the importance of key service process factors to an understanding of dimensions of service quality. 相似文献
