The article, ‘Apraxia of Speech: An Overview’ by Ogar et al., discusses the various aspects of Apraxia of Speech or AOS, which can be broadly described as speech disorder. Scholars have mainly tried to identify its cause and characteristics to define its cognitive and…
Vascular lesion is considered as its leading cause, but scholars believe that trauma and tumors may also result in AOS.
In AOS, there is loss of control in articulation resulting in reduced ability to sequence, time and coordinate the phonemes that lead to speech errors. The articulation is disrupted due to damage in central nervous system. It is characterized by persistent dysprosody or speech having abnormal rhythm, stress and intonation with repeated utterances in order to become articulate. It is often confused with Aphasia or conduction aphasia and Dysarthria. While Aphasia highlights language deficit and cannot select correct phonemes but has speech continuity, AOS uses correct phonemes but cannot articulate due to motor deficiency and therefore, speech is halting and repetitive. On the other hand, Dysarthria affects articulation due to muscle impairment while AOS has linguistic error is due to lack of motor control.
There is more than one type of AOS as defined by the damages in different part of brain. The treatment is often focused on speech articulation therapy that is designed to improve intonation and stress through repetition of words and speech sound. Augmentative devices and alternative means like gestures, drawing, writing etc. are used for severe AOS patients. The research shows that efficacy of treatment mainly relies on experimental designs as per the needs of the patients. The study is hugely significant because it has helped to distinguish it from the various other forms of speech disorders. Most importantly, clear diagnosis has helped clinicians to address its intervention techniques.
I strongly believe that the paper encourages more in depth study of the subject so that new variant of AOS could be identified. AOS is complex in its characterization and causes. As such, it necessitates early deduction so that patients can use appropriate intervention to bring under control the ...

From one that was developed to supplement advanced computer hardware, it has emerged as the primary resource around which hardware is built today. The immense amount of attention which the software field has managed to attract is due to exponential improvement in productivity that it has promised.
Geltner (1993) describes an approach to correct the problem of smoothing and lagging without assuming that true market returns are uncorrelated and unpredictable. Geltner models the structure of the publicly reported index returns including explicit considerations for the effects of the three behavioural factors: appraisal smoothing, temporal aggregates and seasonality of reappraisals.
This is via studying mind and brain coupled with analyzing the correlation that abounds amid the two in understanding how they contribute in influencing a person’s conduct. Neumann discovers how upcoming intellectuals fail to appreciate core biological-based mechanism in understanding human behavior especially mind and brain besides their relations.
Basically, this study has been designed in order to establish the impacts of hourly rounds on patient falls, satisfaction as well as the level of their use of call light. This particular paper is a reproduction of the a quantitative research paper written by Christine M.
Academic search complete. Web. 14 Oct 2013. Hydraulic fracturing entails the natural gas and oil extraction from the ground with the use of proponents and silica proppant is most used. Based on the geological conditions aluminum pellets, artificial ceramics, coated with resin sand and bauxite sintered is applicable; the NIOSH field report confirms that inhaling crystalline silica can cause silicosis, kidney disease, autoimmune disorders, lung cancer and tuberculosis.
The discussion on this ethical and procedural medical dilemma is heated with the fact that research conducted among terminally ill patients indicates that patients' awareness of their terminal diagnosis and their understanding of imminent death impact positively patients' quality of life.
As per the statistics of 2001 Almanac of Chinas Health, about 10 million females undergo induced abortions in China annually out of which 20% to 30% is constituted alone by unmarried young women (Liu & Liu, 2001). Also, teenage pregnancy is
