This study aims to assess the perception that 9th year students have about some key concepts related to the "science of risk" and to evaluate their ability to identify and classify the natural and mixed risks with a greater probability of occurrence, both at national level and in the Metropolitan Area of Porto (MAP). A questionnaire was…

By replicating Cho (2017), this article investigates how second language (L2) learners with an article-less first language acquire two types of English definiteness, anaphoric and nonanaphoric. Mandarin Chinese, as an article-less language, has a demonstrative determiner that shares the same feature set as the English definite article…

The purpose of this study was to examine how classroom language contexts characterized by peer language skills and proportions of dual language learners (DLL) influenced English language development for DLL and non-DLL children. Participants were 2,131 children from 135 classrooms across preschool through Grade 3. Children were classified into…

This study examined the influence of formulaic language on second language (L2) listeners' lower-level processing, in terms of their ability to accurately identify the words in texts. On the one hand, there were reasons for expecting the presence of the formulas to advantage the learners, because the learners would process these formulaic words…

Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

This article reports on a study that was conducted to evaluate value addition in the learning attainments of students in higher education. The subjects in the study were telecommunication engineering students who pursued their programme of study between 2011 and 2013 at the Ghana Technology University College. Using descriptive statistics and…

To explore the differences between how organic chemistry students and organic chemistry professors think about organic chemistry reactions, we administered a card sort task to participants with a range of knowledge and experience levels. Beginning students created a variety of categories ranging from structural similarities to process oriented…

This study explores the effects of extensive audio-visual input with three captioning modes -- unenhanced captions, textually enhanced captions, and no captions -- on learning a variety of L2 grammatical constructions and examines the effects of three learnability factors: construction type, frequency, and recency. A total of 112 participants…

This study examined levels of English proficiency before and during the COVID-19 pandemic among English learner students in grades 3-12 in Texas. In 2020-2021, nearly 750,000 students in grades 3-12--approximately one in five Texas students--were English learner students. In accordance with Texas state law and the Every Student Succeeds Act,…

The purpose of the current investigation was to describe how the artificial neural networks (ANNs) can be used to interpret student performance on cognitive diagnostic assessments (CDAs) and evaluate the performances of ANNs using simulation results. CDAs are designed to measure student performance on problem-solving tasks and provide useful…

In this article we reviewed the shock wave oscillation that occurs when supersonic flows interact with conic, blunt or flat nose of aircraft, taking into account the aerospike attached to it. The main attention was paid to the problem of numerical modeling of such oscillation, flow regime classification, and cases where aerospike attachment can…

In this article reviewed problems of the criminalistic classification building of a person. In the work were used legal formal, logical, comparative legal methods. The author describes classification kinds. Reveal the meaning of classification in criminalistic systematics. Shows types of grounds of criminalistic classification of a person.…

This article is devoted to the problem of corporate culture transformations which are conditioned by changes in social-economic situation. The modern paradigm of knowledge management is assumed to become the main value for forming a new vision of corporate culture.

We present an annotation scheme for classifying differences in the outputs of syntactic constituency parsers when a gold standard is unavailable or undesired, as in the case of texts written by nonnative speakers of English. We discuss its automated implementation and the results of a case study that uses the scheme to choose a parser best suited…

Purpose: As follow-up to a previous study of probes, we evaluated the marking of tense and agreement (T/A) in language samples by children with specific language impairment (SLI) and typically developing controls in African American English (AAE) and Southern White English (SWE) while also examining the clinical utility of different scoring…
