On the Acquisition of Derivational Suffixes by Kuwaiti EFL Learners

This study aims to test the extent to which 90 Kuwaiti EFL learners are aware of the correct use of derivational suffixes in English. It also identifies the mains reasons of the errors that Kuwaiti EFL learners may make. In addition, it investigates whether the English proficiency level of the participants plays a role in their answers on the test. To this end, the participants were tested twice in this study; a multiple-choice test was used to check their comprehension skills, whereas a fill-in the blank test was used to measure their ability to produce the correct derivational suffixes in English. Following data analysis, the results reveal that Kuwaiti EFL learners are fairly aware of the correct use of English derivational suffixes to a certain degree; the total mean on both tests (comprehension = 70% and production = 56%) is 63%. The participants obtained higher percentage of correct answers on the comprehension test (mean= 70%) compared to the production test (mean = 56%). Additionally, the t-test shows that the participants’ English proficiency level plays a central role in their comprehension and production of these suffixes. The performance of the Advanced Learners (ALs) (comprehension = 77% and production = 62%) is better than that of the Intermediate Learners (ILs) (comprehension = 64% and production = 48%) on the tests. In particular, there is a statistically significant difference between the answers of ALs and ILs on both tests. Regarding the types of error made by the participants, I argued that the most noticeable ones are due to: (1) the modification that non-neutral derivational suffixes cause when they are attached to the word (stems/roots); and (2) first language (L1) influence. Finally, the study concludes with some recommendations for further research

An Analysis of Compliment Responses by Kuwaiti EFL Learners: A Pragmatic Approach

This study investigates the extent to which 80 female Kuwaiti EFL learners produce target-like compliment responses when they are communicating in English, through comparing their responses to those of British English speakers. It also examines whether the English proficiency level of Kuwaiti EFL learners plays a role in their responses to compliments in English. Essentially, this study explores whether pragmatic transfer has an impact on the Kuwaiti participants' responses. A Discourse Completion Task (DCT) was given to 50 female native speakers of British English (the control group) and to 80 female Kuwaiti EFL learners (the treatment group), in order to determine whether the responses of the latter group are similar or different to those of the former group. The results reveal that the English proficiency level of the treatment group had no effect on their answers on the DCT. In comparison with the control group, the results also demonstrate that the treatment group transferred both L1 expressions and strategies to respond to compliments in English. This has been attributed to the fact that they may not be aware of any culture-specific nature of verbal communications crosslinguistically, among other reasons. Finally, the study concludes with recommendations for further research

Double Sequence Spaces by Means of Orlicz Functions

We define some classes of double entire and analytic sequences by means of Orlicz functions. We study some relevant algebraic and topological properties. Further some inclusion relations among the classes are also examined

On the Solutions of a General System of Difference Equations

We deal with the solutions of the systems of the difference equations xn+1=1/xn-pyn-p, yn+1=xn-pyn-p/xn-qyn-q, and xn+1=1/xn-pyn-pzn-p, yn+1=xn-pyn-pzn-p/xn-qyn-qzn-q, zn+1=xn-qyn-qzn-q/xn-ryn-rzn-r, with a nonzero real numbers initial conditions. Also, the periodicity of the general system of k variables will be considered

Applications of Hankel and Regular Matrices in Fourier Series

Recently, Alghamdi and Mursaleen (2013) used the Hankel matrix to determine the necessary and suffcient condition to find the sum of the Walsh-Fourier series. In this paper, we propose to use the Hankel matrix as well as any general nonnegative regular matrix to obtain the necessary and sufficient conditions to sum the derived Fourier series and conjugate Fourier series

Temporal LiDAR Scanning in Quantifying Cumulative Rockfall Volume and Hazard Assessment: A Case Study at Southwestern Saudi Arabia

Rockfalls and unstable slopes pose a serious threat to people and property along roads/highways in the southwestern mountainous regions of Saudi Arabia. In this study, the application of terrestrial light detection and ranging (LiDAR) technology was applied aiming to propose a strategy to analyze and accurately depict the detection of rockfall changes, calculation of rockfall volume, and evaluate rockfall hazards along the Habs Road, Jazan Region, Saudi Arabia. A series of temporal LiDAR scans were acquired at three selected sites. Our results show that these three sites have different degrees of hazard due to their geological differences. The mean volume loss of sites A1, A2, and A3 is 327.1, 424.4, and 3.7 L, respectively. Statistical analysis confirms the significance of the influence of site type on rockfall volume, with a probability value of \u3c 0.0105. The rockfall volume and change detection values are then correlated with precipitation, which is a triggering factor. The study also reveals that the use of terrestrial LiDAR could reduce time and effort, increase accessibility, and produce effective solutions. LiDAR could be an indispensable tool for disaster risk assessment, response and recovery process
