Auditory evoked potential in normal hearing and sensorineural hearing loss among Malay and Chinese adults / Ibrahim Amer Ibrahim
No full textNeural plasticity in the human brain is defined as the change of the structure, function, and organization of neurons/nerve cells due to new experiences. Despite the factors causing hearing loss being reported in literature, the exact role of these factors and the changes in the auditory neuron process remains unclear. There is also a dearth of studies on the auditory evoked brain potential in multiple ethnic groups. This research addresses neuronal plasticity, which correlates hearing and speech before and after the onset of hearing impairment in two ethnic groups. This study will play a vital role towards the design and development of efficient hearing aids/implants, speech recognition software, and in the rehabilitation of patients suffering from hearing loss.
This study intends to elucidate the differences in the cortical auditory evoked potential (CAEP) between subjects with normal hearing and sensorineural hearing loss (SNHL). It will also explore the differences and limitations in the CAEP in two ethnic groups (Malay and Chinese) with/without SNHL. This work is limited in its ability to classify CAEP signal based on stimuli sounds for ethnic groups (Malay and Chinese).
The aims of this study could be realized by investigating the impact of different auditory stimuli (Pure Tone and Consonant-Vowel) on the electrophysiological neural representation (waveform morphology, latency, and amplitude) of the CAEP components. This investigation was conducted on Malay and Chinese normal hearing volunteers, as well as those suffering from sensorineural hearing loss.
This study presents accurate and novel formulated indices for classifying brain auditory responses and human hearing abilities. A classification algorithm was used to classify the CAEP responses evoked from multiple auditory stimulus for normal hearing subjects and SNHL patients in the case of both ethnicities.
The results indicated that the SNHL alters the human central auditory system in an adult brain. We concluded that the SNHL subjects elicited greater amplitude with prolonged latencies throughout the majority of the CAEP components when the subjects were exposed to multiple auditory stimuli. The contradiction in the CAEP components (amplitudes and latencies) and classification accuracy between subjects with SNHL and normal subjects was attributed to the neurological deficit in the SNHL patients. The findings suggested that the MMN (MisMatch Negativity), as a diagnostic tool for the hearing-impaired population, was limited (unclear) relative to other CAEP responses. N1, P2, and N2 were the dominant CAEP component in variation and change of the amplitude and latency, reporting the maximum appearing percentages. We also confirmed that there is a higher probability that the Chinese subject groups suffer from hearing impairment at a rate higher than the Malay group. However, the Chinese subjects exhibited excellent distinguishing ability in recognizing auditory stimuli relative to the Malay group
Rubaies of İbrahim Aczî kendî (The last 180 rubaies)
No full text1881-1965 yılları arasında Konya'da yaşayan İbrahim Aczî Kendî, Konya'nın XX. yüzyılda yetiştirdiği önemli şair, gazeteci, araştırmacı, yazar, mutasavvıf ve folklorculardandır. Konya'da öğretmenlik yapan İbrahim Aczî Kendî, Arapça ve Farsça öğrenerek kendini geliştirmiş, tasavvuf, edebiyat ve tarihle ilgili kitaplar hazırlamıştır. İbrahim Aczî Kendî'nin bizzat kendisinin kaleme aldığı, tek nüshası Yusuf Ağa Kütüphanesinde 10465/1 numara ile kayıtlı olan Devr-i Zaman adlı eseri, 360 Farsça rubâî ve bu rubâîlerin Osmanlı Türkçesiyle yazılmış açıklamalarından oluşmaktadır. Bu çalışmada İbrahim Aczî Kendî'nin hayatı incelenmiş, Devr-i Zaman adlı eserinde bulunan 360 rubâînin son 180 tanesi çalışılmıştır. Her bir rubâînin Farsça ana metinleri bilgisayar ortamına aktarılmış, bazen sadece tercüme, bazen de çeşitli açıklamalar içeren Osmanlı Türkçesiyle yazılan kısımlar ise latin harfleriyle aktarılmıştır. İbrahim Aczî Kendî, bu çalışmada ele alınan rubâîlerinde, genellikle ilahi aşk, toplumsal ahlâk, zamandan şikâyet, riya ve kibirden uzak durmanın gerekliliği gibi birçok konuya değinmiştir.İbrahim Aczî Kendî who lived the years between 1881 and 1965 in Konya is an important poet, a journalist, an investigate author, a mystic and a folklorist who raised by Konya in 20th century. İbrahim Aczî Kendi, worked as a tutor in Konya, improved himself by learning Arabian and Persian, prepared books about mysticism, literature and history. Devr-i zaman, which is written by İbrahim Aczî Kendî by himself and whose only transcript is registered with the number 104657/1 in Yusuf Ağa Library, is made of 360 Persian rubaies and their explanation which is written in Ottoman Turkish. In this study İbrahim Aczî Kendî's life and last 180 of 360 Persian rubaies are studied. Each of rubaies' Persian main texts are transferred to electronic environment. Parts that sometimes include translation, sometimes also include various types of explanations written Ottoman Turkish are transferred with Latin letters. İbrahim Aczî Kendî, rubaies that handled in this study, touches on many topics, such as sociel ethics, complaints about today's youht, hypocrisy and staying away from and arrogance

External interventions and the duration of civil wars
No full textThe authors combine an empirical model of external intervention, with a theoretical model of civil war duration. Their empirical model of intervention allows them to analyze civil war duration, using"expected"rather than"actual"external intervention as an explanatory variable in the duration model. Unlike previous studies, they find that external intervention is positively associated with the duration of civil war. They distinguish partial third-party interventions that extend the length of war, from multilateral"peace"operations, which have a mandate to restore peace without taking sides - and which typically take place at war's end, or at least when both sides have agreed to a cease-fire. In a future paper, the authors will examine whether partial third-party interventions - whatever their effect on a war's duration - increase the risk of war's recurrence. If that proves true, then even if interventions reduce the length of civil war, they may do so at the cost of further destabilizing the political system, and sowing the seeds of future rebellion.Children and Youth,Peace&Peacekeeping,Post Conflict Reconstruction,Post Conflict Reconstruction,International Affairs,Post Conflict Reconstruction,Social Conflict and Violence,Peace&Peacekeeping,Post Conflict Reconstruction,International Affairs
