Language Needs

Word prompt programs are computer software programs or program features that are used in addition to basic word processing. These programs provide word lists from which a user selects a desired word and inserts it into a line of text. This software is used to support individuals with severe speech, physical, and learning disabilities. This tutorial describes the features of a variety of word prompt programs and reviews the current literature on the use of these programs by people with oral and written language needs. In addition, a matrix that identifies the features contained in eight sample word prompt programs is provided. The descriptions of features and the matrix are designed to assist speech-language pathologists and teachers in evaluating and selecting word prompt programs to support their clients' oral and written communication.

Language Needs

English for Academic Purposes course focusing on the academic language needs of students is a subfield of English for Specific Purposes (ESP). It is a type of specialized course to integrate specific subject matter, language content, and material based on learners’ needs. The study aims to evaluate the British Council’s English for Academic Purposes (EAP) coursebook in terms of content, sequencing, learners’ autonomy, motivation, feedback and focus on language skills. Furthermore, the study tries to provide a general perception of the usefulness and effectiveness of the coursebook for undergraduate students. The EAP Students’ Manual coursebook is used as a primary source for the data collection. The researcher has chosen Nation & Macalister (2010) model of language teaching principles to analyze and discuss the data. The study found the coursebook a useful, effective and an appropriate source of English language learning in terms of the investigated aspects of the book. The findings report that the coursebook provides practice and practical usage in all domains of the academically required English language skills. It helps the students to build language competency and to be more independent learners. In addition, it provides an opportunity to the learners to think in the target language, use the language more practically and learn it in a natural type of environment. The study concludes and suggests that the content needs to be supplemented with English language audios and videos presenting the students relevant documentaries and helping material in order to make the coursebook and the learning process more useful, effective, interesting and motivating. Furthermore, the study recommends that while choosing /designing a coursebook for a certain course, it needs to be evaluated following the various criteria and language-teaching-principles suggested by different language researchers.

AbstractTethered submerged buoy is used extensively in the field of marine engineering. In this paper considering the effect of wave, the nonlinear dynamics behavior of tethered submerged buoy is debated under wave loadings. According to Newton’s second law, the dynamic of the system is built. The coupling factor of the system is neglected, the natural frequency is calculated. The dynamic responses of the system are analyzed using Runge–Kutta method. Considering the variety of the steepness kA, the phenomenon of dynamic behavior can be periodic, double periodic and quasi-periodic and so on. The bifurcation diagram and the largest Lyapunov exponent are applied to judge the nonlinear characteristic. It is helpful to understand the dynamic behavior of tethered submerged buoy and design the mooring line of tethered submerge buoy.

In underwater wet welding, the unstable welding process caused by the generation and rupture of bubbles and the chilling effect of water on the welding area result in low quality of welded joints, which makes it difficult to meet the practical application of marine engineering. To improve the process stability and joining quality, a mixture of welding flux with a water glass or epoxy resin was placed on the welding zone before underwater welding. In this paper, welds’ appearance, geometry statistics of welds’ formation, welding process stability, slag structure, microstructure, pores and mechanical properties were investigated. It was found that with the addition of water glass in the mixture, the penetration of weld was effectively increased, and the frequency of arc extinction was reduced. Though the porosity rose to a relatively high level, the joints’ comprehensive mechanical properties were not significantly improved. Notably, the applied epoxy resin completely isolated the surrounding water from the welding area, which greatly improved process stability. Furthermore, it benefited from the microstructure filled with massive acicular ferrite, the average elongation and room temperature impact toughness increased by 178.4%, and 69.1% compared with underwater wet welding, respectively, and the bending angle of the joint reaches to 180°.
