This study aims at investigating the equivalence of mathematics try out scores junior high school through anchor. In study, 2 Parameters Logistic (2PL) model Item Response Theory (IRT) analysis was used Haebara method. The estimation step equating parameter utilized equateIRT package in R program. results show that relationship between questions 1 and cannot be said to equivalent. After analyzi...

Abstract We investigated the predictive processing of grammatical number information through stem-vowel alternations in German strong verbs by adult first language (L1) speakers and Dutch-speaking advanced second (L2) learners German, influence working memory awareness (i.e., whether participants consciously registered cue) thereon. While changed stem vowels indicate a singular referent (e.g., ...

Artificial intelligence (AI) technologies have the potential to reduce workload for second language (L2) teachers and test developers. We propose two AI distractor-generating methods creating Chinese vocabulary items: semantic similarity visual similarity. Semantic refers antonyms synonyms, while phenomenon that phrases share one or more characters in common. This study explores construct valid...

Item response theory (IRT) is widely applied in the human sciences to model persons' responses on a set of items measuring one or more latent constructs. While several R packages have been developed that implement IRT models, they tend be restricted respective pre-specified classes models. Further, most implementations are frequentist while availability Bayesian methods remains comparably limit...

Many generativist accounts (e.g., Wexler, 1998) argue for very early knowledge of inflection on the basis of very low rates of person/number marking errors in young children's speech. However, studies of Spanish (Aguado-Orea & Pine, 2015) and Brazilian Portuguese (Rubino & Pine, 1998) have revealed that these low overall error rates actually hide important differences across the verb paradigm. ...

Day by day, wireless networking technology and mobile computing devices are becoming more popular for their mobility as well as great functionality. Now it is an extremely growing demand to process mobile transactions in mobile databases that allow mobile users to access and operate data anytime and anywhere, irrespective of their physical positions. Information is shared among multiple clients...

Uniform diagnostic criteria for the night eating syndrome (NES), a disorder characterized by a delay in the circadian pattern of eating, have not been established. Proposed criteria for NES were evaluated using item response theory (IRT) analysis. Six studies yielded 1,481 Night Eating Questionnaires which were coded to reflect the presence/absence of five night eating symptoms. Symptoms were e...

Gold nanoparticles can be used as contrast agents for bio-imaging applications. Here we studied multi-photon luminescence (MPL) of gold nanorods (GNRs), under the excitation of femtosecond (fs) lasers. GNRs functionalized with polyethylene glycol (PEG) molecules have high chemical and optical stability, and can be used as multi-photon luminescent nanoprobes for deep in vivo imaging of live anim...
