Abstract: Language is the most important part of culture. Because of that language is made up of writing and oral expressions, it implies that these expressions should be analyze in detail. In general, the people express theirselves orally in their daily lives. That’s why, oral expression should be made more effective. The goal of the study is to develop a measuring tool that can measure oral ability reliable and valid. The working group of this research has 342 students who get teaching formation education at Selcuk University of Konya City in Turkey. There are 230 female studens and 112 male students in this group. The students were wanted to evaluate the speak of the academic staff who did in previous lecture. Scale items were prepared by doing literatüre survey and getting comments of consultants. 111 items of the scale were reduced to 24 items after doing reliability and validity analyses and getting advices of consultants. In the scale, there are 20 items that can show positive situaitons and 4 items that show negative situations. The negative items of the scale are being pointed reversibly.To prove the validity of the scale, factor analyses that anatomize and confirm. The validity of scale was made by applying Cronbach alpha, Spearman Brown, Gutmann Split-Half Techniques, corrected item correlations and calculating the t-test values which are related with the 27 percent of up-down difference. After these, it was concluded that this scale is safe and valid. Dil, bir toplumun kültürünün en nemli unsurudur.

Abstract: An unanswered question in adult language learning or late bi and multilingualism is why individuals show marked differences in their ability to imitate foreign accents. While recent research acknowledges that more adults than previously assumed can still acquire a “native” foreign accent, very little is known about the neuro-cognitive correlates of this special ability. We investigated 140 German-speaking individuals displaying varying degrees of “mimicking” capacity, based on natural language text, sentence, and word imitations either in their second language English or in Hindi and Tamil, languages they had never been exposed to. The large subject pool was strictly controlled for previous language experience prior to magnetic resonance imaging. The late-onset (around 10 years) bilinguals showed significant individual differences as to how they employed their left-hemisphere speech areas: higher hemodynamic activation in a distinct fronto-parietal network accompanied low ability, while high ability paralleled enhanced gray matter volume in these areas concomitant with decreased hemodynamic responses. Finally and unexpectedly, males were found to be more talented foreign speech mimics.

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.61005
Abstract: This research aims to highlight the importance of developing creativity in the school environment by promoting quality education to gifted students, with contributions from Vygotsky and Piaget. For Vygotsky creativity is inherent in the human condition, and it is the most important activity because it is the expression of consciousness, thought and language. It is the highest expression of subjectivity (Vygotsky, 2010). According to Piagetian theory, Stoltz (2013) points out that although the source of creativity is a mystery to Piaget, it manifests itself doubly: in the construction of knowledge structures and construction of real or structure and cognitive functioning. The method of this research is a bibliographic study of the area of high ability/giftedness, the cultural-historical theory of Vygotsky and Piaget’s genetic epistemology. We conclude that for Vygotsky (2008) as well as for Piaget (1968) the environment has essential importance to the development of creative potential. In the environment the child has his/her experiences that stimulate curiosity, desire to learn, fantasy and imagination. The teacher should enable gifted students to share their high abilities with their couple performing challenging activities in a stimulating and responsive environment.
Can Overconfident Executives Restrain Overinvestment?  [PDF]
Xuanbing Liu
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.88073
Abstract: This paper uses the data of the public company from 2013 to 2015 to explore the relationship between executives’ overconfidence and overinvestment when the company’s financing ability is different. Unlike previous studies, the result of this study shows that overconfidence may curb overinvestment when the company’s financing capacity is poor. It is when the financing capacity is strong that overconfidence will exacerbate overinvestment. A lot of studies show that overconfident executives increase overinvestment because of underestimation of risk, and our study gives a different view.

Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.69017
Abstract: This paper establishes the evaluation model of innovation incubation ability by using optimal combination weight and analyzes the innovation incubation ability of high technology industry based on data from 31 provinces during the period of 2008-2012. The results show that from general prospective, the innovation incubation ability of high technology industry enters into the slow development phase in accord with “W” shape in China; from the regional prospective, Guangdong, Jiangsu and Beijing are in the lead; Tibet, Ningxia lag behind other regions; the rank of some regions is changeful; from sub-ability prospective, while resource investment ability and research and development ability overall show a downward trend, economic transformation ability shows a upward trend; besides, research and development ability makes more important contribution to the innovation incubation ability of high technology industry.
The Misconceived Search for the Meaning of “Speech” in Freedom of Speech  [PDF]
Larry Alexander
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.51005
Abstract: In this (very) short essay, I establish these points: All speech is symbolic; any conduct can be used to communicate a message (i.e., symbolically); government’s purpose in regulating, and not a speaker’s intention to communicate, defines the realm of freedom of expression; and determining the value of speech has a denominator problem.
Iterative spectral subtraction method for millimeter-wave conducted speech enhancement  [PDF]
Sheng Li, Jian-Qi Wang, Ming Niu, Xi-Jing Jing, Tian Liu
Journal of Biomedical Science and Engineering (JBiSE) , 2010, DOI: 10.4236/jbise.2010.32024
Abstract: A non-air conducted speech detecting method has been developed in our laboratory by using millimeter wave radar technology. Because of the special attributes of the millimeter wave, this method may considerably extend the capabilities of traditional speech detecting methods. However, radar speech is substantially degraded by additive combined noises that include radar harmonic noise, electrocircuit noise, and ambient noise. This study, therefore, proposed an iterative spectral subtraction method which can be adaptively estimate noise spectrum at every iteration, and reduce the musical noise remained in the previous spectral subtraction process. Results from simulations as well as evaluations confirm that the proposed method satisfactorily reduces whole-frequency and musical noises and produces good speech quality.

In dentistry, speech evaluation is important for appropriate orofacial dysfunction rehabilitation. The speech intelligibility test is often used to assess patients’ speech, and it involves an evaluation by human listeners. However, the test has certain shortcomings, and an alternative method, without a listening procedure, is needed. The purpose of this study was to test the applicability of an automatic speech intelligibility test system using a computerized speech recognition technique. Speech of 10 normal subjects, when wearing a dental appliance, was evaluated using an automatic speech intelligibility test system that was developed using computerized speech recognition software. The results of the automatic test were referred to as the speech recognition scores. The Wilcoxon signed rank test was used to analyze differences in the results of the test between the following 2 conditions: with the palatal plate in place and with the palatal plate removed. Spearman correlation coefficients were used to evaluate whether the speech recognition score correlated with the result of conventional intelligibility test. The speech recognition score was significantly decreased when wearing the plate (z = -2.807, P = 0.0050). The automatic evaluation results positively correlated with that of conventional evaluation when wearing the appliance (r = 0.729, P = 0.017). The automatic speech testing system may be useful for evaluating speech intelligibility in denture wearers.

Intelligibility of Reverberant Speech with Amplification: Limitation of Speech Intelligibility Metrics, and a Preliminary Examination of an Alternative Approach  [PDF]
Doheon Lee, Eunju Gong, Densil Cabrera, Manuj Yadav, William L. Martens
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.32028

This study examines the effect of speech level on intelligibility in different reverberation conditions, and explores the potential of loudness-based reverberation parameters proposed by Lee et al. [J. Acoust. Soc. Am., 131(2), 1194-1205 (2012)] to explain the effect of speech level on intelligibility in various reverberation conditions. Listening experiments were performed with three speech levels (LAeq of 55 dB, 65 dB and 75 dB) and three reverberation conditions (T20 of 1.0 s, 1.9 s and 4.0 s), and subjects listened to speech stimuli through headphones. Collected subjective data were compared with two conventional speech intelligibility parameters (Speech Intelligibility Index and Speech Transmission Index) and two loudness-based reverberation parameters (EDTN and TN). Results reveal that the effect of speech level on intelligibility changes with a room’s reverberation conditions, and that increased level results in reduced intelligibility in highly reverberant conditions. EDTN and TN explain this finding better than do STI and SII, because they consider many psychoacoustic phenomena important for the modeling of the effect of speech level varying with reverberation.
