Web technology in an instructional environment is primarily dedicated to distributing course materials to supplement traditional classroom learning. It also uses designed intelligence to adapt to learners' specific needs. The main purposes of this study were to construct and determine the efficiency of adaptive web-based instruction for LIS students. The web-based content was designed to adapt to three levels of learning ability: high, moderate and low. The system automatically collects data concerning each learner's behavior, determines the level of learning ability and provides suitable content for each learner. In addition, this web-based instruction evaluated using 80/80 standard efficiency criteria and compared the learning achievement of the students who learned through the adaptive WBI and those who learned through traditional m...
This study focuses on the relationship of one cognitive ability test on long-term job performance as measured by personnel data. Archival data from over 3,000 employees at an international technology company were used to assess how aptitude test scores relate to both objective and subjective job performance measures. Supervisory performance ratings, level of promotion, and salary increase significantly contributed to variance in test scores; however, these results were inconsistent. Number of training courses did not have a significant relationship with test scores. Additionally, type of turnover did not moderate the relationship between aptitude test scores and job performance. These results indicate that although aptitude test score is related to long term job performance factors, other factors account for the majority of the varianc...
A child's ability to learn in school and school performance are affected by various factors. Variables that affect learning and academic performance in 46 children, 4 - 7 years old, were examined. Children, parents, and teachers completed questionnaires rating children's attitudes and behavior toward school. Children completed a computerized matching-to-sample (MTS) task. The MTS trained the children to form 3 stimulus classes. One stimulus class included three arbitrary stimuli, the others contained a positively or negatively valenced stimulus, a school-related stimulus, and an arbitrary stimulus. Class formation performance was assessed. Rate of learning predicted attitudes toward school, school attitudes predicted academic performance; however a hypothesized mediation effect of attitudes was not demonstrated. No significant differen...
Exchange Traded Funds (ETFs) são fundos de investimento transaccionados em bolsa que foram criados recentemente e têm vindo a crescer bastante nos últimos anos. Apesar do extenso número de investigações sobre este assunto, existem poucos dedicados ao estudo de Commodity ETFs e à sua aptidão como investimento alternativo em commodities. Assim, de forma a conhecer a sua viabilidade como investimento e a sua capacidade em replicar o benchmark, foi analisado uma amostra de 27 ETFs de metais, transaccionados na NYSE Arca.
O foco desta tese é a capacidade de replicação semanal dos ETFs, avaliados através de regressão linear, testes de tracking error e indicadores de análise de performance. Depois, é ainda testado o mispricing potencial, a fim de perceber se os ETFs são transaccionados pelo seu “preço justo”, ou se os seus preços tendem a se...
Visual–spatial ability is a multifaceted component of intelligence that has predictive validity for future achievement in science, technology, engineering, and mathematics (STEM) occupations. Although identification and development of STEM talent is a national priority, visual–spatial ability is rarely measured and relatively neglected in gifted education. Quantitative and verbal reasoning abilities are favored over nonverbal abilities in talent searches and gifted programs, which causes some high-spatial, gifted students to be overlooked. Creative production in STEM requires visual–spatial ability, and this ability must be developed in gifted education. Theories of intelligence and testing have advanced to provide methods for identification of specific cognitive abilities, such as visual–spatial ability. However, for these students to...
Does diversity of cognitive ability among market participants increase mispricing? Does common knowledge of heterogeneity in relation to cognitive ability of market participants further increase mispricing? We investigated these questions by measuring subjects' cognitive ability and categorizing those above median ability as type `H' and those below median ability as type `L'. We then constructed three market types, each containing six traders: 6H, 6L, and 3H3L. Subjects were informed of their own cognitive type and, depending on the treatment, that of the others in their market. We found that heterogeneous markets (3H3L) generated significantly larger mispricing than homogeneous markets (6H or 6L) regardless of whether subjects were informed about the cognitive type of others in their market. Thus, diversity of cognitive ability among...
This paper develops two methods for estimating the effect of schooling on achievement test scores that control for the endogeneity of schooling by postulating that both schooling and test scores are generated by a common unobserved latent ability. These methods are applied to data on schooling and test scores. Estimates from the two methods are in close agreement. We find that the effects of schooling on test scores are roughly linear across schooling levels. The effects of schooling on measured test scores are slightly larger for lower latent ability levels. We find that schooling increases the AFQT score on average between 2 and 4 percentage points, roughly twice as large as the effect claimed by Herrnstein and Murray (1994) but in agreement with estimates produced by Neal and Johnson (1996) and Winship and Korenman (1997). We extend...
Purpose - It is now acknowledged that Early Supplier Involvement (ESI) in product development confers a competitive advantage. However, the implementation of ESI has been further extended to consider successful product development, particularly through the Relationship Assessment Programme (RAP) model (Lamming et al., 1996), as an interactive process between a customer firm and a supplier. We adopt this point of view in our paper aiming at shaping the outline of customer's ability to co-design with suppliers in New Product Development (NPD). Design/methodology/approach - We adopted an action research approach based on longstanding interactions between researchers and of six French industrial manufacturers for the co-construction of local knowledge which can finally serve to build generic actionable knowledge. The feedback provided by a...
