This article explores the relative importance of different socio-demographic and practice-oriented factors that are related to proficiency in problem solving in technology-rich environments (PSTREs) and by extension may be related to complex problem solving (CPS). The empirical analysis focuses on the proficiency measurements of PSTRE made available by the Programme for the International Assessment of Adult Competencies, which is relevant for gaining insight on some of the factors related to CPS. The purpose was to examine the relationship between the broad information processing experience that individuals gather in different contexts over the lifespan, and the chances to develop problem-solving skills that adults receive in different socio-demographic profiles. Results reveal that socio-demographic factors such as age, education and immigration status as well as practice-oriented factors such as ICT use and reading practice at and outside work are strongly related to proficiency. 相似文献

An attempt was made at recording structured sport in non-White schools in Cape Town, South Africa, prior to 1956. The study was introduced with a historical presentation of sport at mission schools. It was shown how these schools inherited a legacy of deprivation and neglect that impacted upon sport participation. Yet, champion sportspersons at these schools gained some recognition in a racist and hostile society. This was possible due to the efforts of a few Teachers' League of South Africa (TLSA) campaigners who saw sport development as part of their mission of uplifting children in their charge. The TLSA attempted organising athletic meetings from 1916 onwards. Teachers belonging to this organisation were instrumental in establishing the first mass-based school sport organisation in Cape Town in 1928, the Central School Sports Union (CSU). This organisation was the only avenue of meaningful sport participation for most of Cape Town's marginalised children. A study of the CSU enables historians to open a window not only on social and political complexities of school sport but also on the broader early twentieth-century Cape society. 相似文献

The purpose of this article is to develop a statistical model that best explains variability in the number of school days suspended. Number of school days suspended is a count variable that may be zero-inflated and overdispersed relative to a Poisson model. Four models were examined: Poisson, negative binomial, Poisson hurdle, and negative binomial hurdle. Additionally, the probability of a student being suspended for at least 1 day was modeled using a binomial logistic regression model. Of the count models considered, the negative binomial hurdle model had the best fit. Modeling the probability of a student being suspended for at least 1 day using a binomial logistic regression model with interactions fit both the training and test data and had adequate fit. Findings here suggest that both the negative binomial hurdle and the binomial logistic regression models should be considered when modeling school suspensions. 相似文献

Contextual feature selection for text classification 总被引:1,自引:0,他引:1
We present a simple approach for the classification of “noisy” documents using bigrams and named entities. The approach combines conventional feature selection with a contextual approach to filter out passages around selected features. Originally designed for call for tender documents, the method can be useful for other web collections that also contain non-topical contents. Experiments are conducted on our in-house collection as well as on the 4-Universities data set, Reuters 21578 and 20 Newsgroups. We find a significant improvement on our collection and the 4-Universities data set (10.9% and 4.1%, respectively). Although the best results are obtained by combining bigrams and named entities, the impact of the latter is not found to be significant. 相似文献

Active ageing has become a policy concept that serves as an important response to the ageing of many societies, primarily because it is thought to lead to positive outcomes such as increased employment, productivity, health and other well‐being into older ages. This article presents results of an analysis of the relationship between attaining qualifications at older ages and active ageing in later life. The analysis is based on data made available by the Programme for the International Assessment of Adult Competencies (PIAAC). Results of the analysis show that adults who attain higher levels of qualifications in mid to later life are associated with an increased probability of, being employed, participating in continued learning, and scoring higher on the PIAAC literacy scale when they are older. The findings suggest that open and flexible formal education structures at all levels is good for activating the population to be employed, to engage in continued learning and to develop and maintain literacy skills into older ages. 相似文献

The language children hear presents them with a multitude of co-occurrences between words and things in the world, and they must repeatedly determine which among these manifold co-occurrences is relevant. Social factors—such as cues regarding the speaker's referential intent—might serve as one guide to whether word-object covariation should be registered. In 2 studies, infants (15–20 months and 18–20 months in Studies 1 and 2, respectively) heard novel labels at a time when they were investigating a single novel object; in one case the label was uttered by a speaker seated within the infant's view and displaying concurrent attention to the novel toy (coupled condition), whereas in the other case the label emanated from a speaker seated out of the infant's view (decoupled condition). In both studies, subsequent comprehension questions indicated that infants of 18–20 months registered a stable link between label and object in the coupled condition, but not in the decoupled condition, despite the fact that covariation between label and object was equivalent in the 2 conditions. Thus, by 18–20 months children are inclined to establish a mapping between word and object only when a speaker displays signs of referring to that object. 相似文献
