AbstractWide dynamic range compression (WDRC) has been widely used in hearing aid technology. However, several reports indicate that WDRC may improve audibility at the expense of speech intelligibility. As such, a modified amplification compression scheme, named adaptive compression, was developed. However, the effect of compression strategies on speech perception in pediatric hearing aid users has not been clearly reported.The purpose of the present study was to investigate the effect of adaptive compression and fast-acting WDRC processing strategies on sentence recognition in noise with Mandarin, pediatric hearing aid users.This study was set up using a double-blind, within-subject, repeated-measures design.Twenty-six children who spoke Mandarin Chinese as their primary language and had bilateral sensorineural hearing loss participated in the study.Sentence recognition in noise was evaluated in behind-the-ear technology with both adaptive compression processing and fast-acting WDRC processing and was selected randomly for each child. Percent correct sentence recognition in noise with fast-acting WDRC and adaptive compression was collected from each participant. Correlation analysis was performed to examine the effect of gender, age at assessment, and hearing threshold of the better ear on signal-to-noise ratio, and a paired-samples t test was employed to compare the performance of the adaptive compression strategy and fast-acting WDRC processing.The mean percentage correct of sentence recognition in noise with behind-the-ear technology with fast-acting WDRC and adaptive compression processing were 62.24% and 68.71%, respectively. The paired-samples t test showed that the performance of the adaptive compression strategy was significantly better than the fast-acting WDRC processing (t = 3.190, p = 0.004).Compared with the fast-acting WDRC, adaptive compression provided better sentence recognition in noise for Mandarin pediatric hearing aid users.

Introduction: The list of contraindications for IV tPA in acute ischemic stroke (AIS) is often too long and may lead to physicians opting to offer no treatment for certain strokes. An alternative treatment is proposed in cases where IV tPA is not an option due to time-window restrictions or contraindications. We compared the stroke severity, outcomes and safety of IV eptifibatide when compared with IV tPA. Methods: Patients who presented to a community based university affiliated comprehensive stroke center from 2012-15 with AIS over a two-year period were included in the study. Those who qualified for IV tPA, and were treated, were compared with patients who only received IV eptifibatide. The initial NIH Stroke Score (NIHSS), 24-hour NIHSS, discharge NIHSS (DCNIHSS), discharge mRS (DCmRS) and symptomatic ICH rates were compared with a paired samples t-test to determine significance of difference between the means. SPSS Version 22 was used for all data analysis. Results: A total of 864 patients presented with AIS in the evaluated time period and of those 166 met study criteria. There were 119 patients who received IV tPA alone (group A) and 47 patients received eptifibatide (group B). The mean initial NIHSS, 24-NIHSS, DCNIHSS, DCmRS and percent bleeding complications for group A were: 11.2, 10.8, 8.6, 3.1 and 6%. For group B the figures were: 6.7, 4.8, 4.3, 1.7 and 0%, respectively. Group A was compared with group B in a paired samples T-test and yielded -4.3, -6.2, -6, -1.5 (p=.0001 to .04) for initial, 24-hour, discharge NIHSS and discharge mRS, respectively. The difference between initial and discharge NIHSS between the two groups was -2.7 (p=.009), favoring IV tPA. Conclusion: In patients who are either outside the time-window or with contraindications to IV tPA, eptifibatide may be a safe alternative and appears to be efficacious. None of the patients who were started on eptifibatide had bleeding complications and they had a statistically significant improvement in their level of disability and stroke severity at discharge. A limitation of this study is that patients in group A had significantly worse initial NIHSS compared with group B. To better evaluate the efficacy of eptifibatide, a larger, prospective study should be initiated.

Reasoning Skills

Reasoning skills are very important in encouraging students to think more critically and logically, as depicted in the Malaysian Education Development Plan (2013-2025). Therefore, this study looked into improving the Differentiation Reasoning Level (DRL) of reasoning skills among students for a topic in the Additional Mathematics subject,  known as Differentiation, through reasoning learning strategy. The study participants consisted of a total of 31 students from a secondary boarding school in Johor, selected through a purposive sampling method. A pre-test was carried out for the participants, from the advanced level, followed by a number of repetition tests, before the post-test assessment was conducted. The data collection for this study employed a set of Reasoning Test on Differentiation (RTD) and 10 sets of learning activities on Differentiation based on modified Marzano Rubric for Specific Task of Situations (1992). This dimension involved four types of reasoning skills, namely,  comparison, classification, inductive, and deductive. The survey data, through paired samples t-test, revealed a significant difference between the mean scores in pre-test and post-test (p <0.05). In addition, the paired sample t-test showed a significant difference on the level of reasoning among students from each construct in the reasoning skills before and after using this module. In conclusion, the Marzano Model of Dimensional Learning (1992) is a thinking skill model that can help improve students' reasoning skills. The model covers analysis aspects of what has been learned by implementing the process of identifying reasons, which will help students to add and expand their knowledge. The findings also implied that, the processes of teaching and learning play an important role in ensuring students’ capability to emphasize on the implementation process of reasoning skills
