The purpose of this single-subject longitudinal study was to examine the Spanish and English biliterate development of U.S. Latino Spanish/English speaking students, who we call emerging bilingual students, as they participated in an innovative biliteracy instructional program titled Literacy Squared®. Findings indicate that across the three years of the study, participating students made gains in Spanish and English reading and writing. This study provides support for Literacy Squared as an innovative biliterate program. Further, the study provides evidence for the need to consider alternative methods to document Latino Spanish/English students’ biliteracy development such as through the use of biliterate trajectories. 相似文献

Knowledge sharing is an acknowledged pre-requisite for effective knowledge management. There is an extensive literature upon knowledge sharing practices and potential barriers. There is increasing recognition of the value of knowledge about customers within organisations. There are often several distinct avenues through which such knowledge is channelled. An assessment tool of knowledge flows is used to identify patterns in knowledge sharing for different facets of knowledge about customers within a case study organisation. An analysis is undertaken of sharing of knowledge about customers among customer service, sales and operations management teams, within the teams with peers, horizontally with other teams, and vertically within the organisation. The study demonstrates that it is possible to identify patterns of sharing knowledge about customers. The research highlights the value of the approach towards analysing knowledge sharing in organisations generally. 相似文献

Following the success of Sony Corporation's`AIBO,' robot cats and dogs are multiplyingrapidly. ``Robot pets' employing sophisticatedartificial intelligence and animatronictechnologies are now being marketed as toys andcompanions by a number of large consumerelectronics corporations.It is often suggested in popular writing aboutthese devices that they could play a worthwhilerole in serving the needs of an increasinglyaging and socially isolated population. Robotcompanions, shaped like familiar householdpets, could comfort and entertain lonely olderpersons. This goal is misguided and unethical. While there are a number of apparent benefitsthat might be thought to accrue from ownershipof a robot pet, the majority and the mostimportant of these are predicated on mistaking, at a conscious or unconscious level,the robot for a real animal. For an individualto benefit significantly from ownership of arobot pet they must systematically deludethemselves regarding the real nature of theirrelation with the animal. It requiressentimentality of a morally deplorable sort. Indulging in such sentimentality violates a(weak) duty that we have to ourselves toapprehend the world accurately. The design andmanufacture of these robots is unethical in sofar as it presupposes or encourages thisdelusion.The invention of robot pets heralds thearrival of what might be called ``ersatzcompanions' more generally. That is, ofdevices that are designed to engage in andreplicate significant social and emotionalrelationships. The advent of robot dogs offersa valuable opportunity to think about the worthof such companions, the proper place of robots in society and the value we should place on ourrelationships with them. 相似文献

In 19 elite schoolboy rowers, the relationships between anthropometric characteristics, metabolic parameters, strength variables and 2000-m rowing ergometer performance time were analysed to test the hypothesis that a combination of these variables would predict performance better than either individual variables or one category of variables. Anthropometric characteristics, maximal oxygen uptake (V O 2m ax ), accumulated oxygen deficit, net efficiency, leg strength and 2000-m rowing ergometer time were measured. Body mass, V O 2max and knee extension correlated with 2000-m performance time (r = -0.41, -0.43 and-0.40, respectively; P 0.05), while net efficiency and accumulated oxygen deficit did not. Multiple-regression analyses indicated that the prediction model using anthropometric variables alone best predicts performance (R = 0.82), followed by the equation comprising body mass, V O 2max and skinfolds (R = 0.80). Although the regression equations increased the predictive power from that obtained using single variables, the hypothesis that a prediction model consisting of variables from different physiological categories would predict performance better than variables from one physiological category was not supported. 相似文献

Needs assessment is a systematic and systemic process intended to identify and define gaps between current performance and desired performance. Needs assessments are most beneficial if they address issues that affect successful accomplishment of operational or tactical processes as well as outcomes that allow an organization to meet its overall strategic goals. A team of graduate students took on a needs assessment project to ascertain the causes of declining accuracy in a key task in an aerospace manufacturing process. The project encountered numerous barriers within the client organization, but the team systematically applied human performance technology methods in multiple stages to gather and analyze the available data. The end result was a set of identified root causes and recommended interventions focused on improving performance. 相似文献
