The Effect of Congruency and Frequency of Exposures on the Learning of L2 Binomials

Although extensive research has been carried out on opaque formulaic language where the meaning is not the sum of the individual words (i.e., idioms and many collocations), it is still not clear how cross-language congruency and frequency of exposure influence the learning of transparent formulaic language in an L2. In the current study, self-paced reading along with offline word order recognition tasks were used to investigate the role of cross-language congruency and the frequency of exposure on the learning and processing of fully transparent binomials. In the self-paced reading, Arabic second language learners of English and native English speakers encountered three types of binomial phrases either two or five times in English texts: English-only binomials, Arabic-only binomials that were translated into English, and congruent binomials (acceptable in English and Arabic). A subsequent offline task revealed that both native and non-native speakers developed knowledge of the ‘correct’ order of binomials (i.e., fish and chips, not chips and fish) after only two exposures in the self-paced reading. Native speakers were more accurate on congruent and English-only items than Arabic-only items, while non-natives speakers exhibited no differences in accuracy across the binomial types. The offline task showed that native speakers responded faster to congruent and English-only items than Arabic-only, and non-native speakers responded faster to congruent items than English-only and Arabic-only. The frequency of exposure had no effect, with no difference in response times and accuracy between two and five exposures.

Adapting natural language processing and sentiment analysis methods for an intervention in older adults: Positive perceptions of health and technology.

Older adults frequently participate in behavior change studies, yet it is not clear how to quantify a potential relationship between their perception of the intervention and its efficacy. We assessed the relationship between participant sentiment toward the intervention from follow-up interviews with physical activity and questionnaires for the perception of health. Sentiment was calculated using the transcripts of exit interviews through a bag of words approach defined as the sum of positive and negative words in 28 older adults with obesity (body mass index ≥30kg/m2). Mean age was 73 years (82% female), and 54% lost ≥5% weight loss. Through linear regression we describe a significant association between positive sentiment about the intervention and weight loss; positive sentiment on technology and change in PROMIS-10 physical health and reduced physical activity time, while controlling for sex and age. This analysis demonstrates that sentiment analysis and natural language processing in program review identified an association between perception and topics with clinical outcomes.

Mobile-assisted vocabulary learning through the Shanbay App outside the classroom: Effects of self-regulation and peer scaffolding.

Recent decades have witnessed an increasing academic interest in mobile-assisted vocabulary learning. To explore the possible influencing factors on learning outcomes, this study aimed at examining the effects of self-regulation and peer scaffolding on mobile-assisted vocabulary learning among undergraduate students using Shanbay App beyond the classroom. To this end, altogether 71 intermediate-level English learners aged 17–19 years were chosen as participants, with 37 in the experimental group (with peer scaffolding) and 34 in the control group (without peer scaffolding). Data were collected through the Shanbay App regarding participants’ vocabulary learning performance, a self-regulation questionnaire and semi-structured interviews. The results of factorial ANOVA revealed that peer scaffolding significantly affected mobile vocabulary learning in terms of the days spent in vocabulary learning and the sum of words participants have learned; a main effect of self-regulation and an interaction effect of self-regulation and peer scaffolding were also observed on the sum of learned words. The research is innovative in providing a motivational peer scaffolding framework in mobile vocabulary learning settings, and may provide pedagogical implications for vocabulary teaching in EFL context in higher education.

The article aims to clarify the importance of lexicon computing in the fields of computational linguistics, as it serves the various sciences and knowledge in developed countries, in the contemporary world, as the computer provides great services for linguistic and literary research by helping to prepare blog dictionaries, and what is meant by blog dictionaries are: All lexical works Which are based on the lexical setting of the sum of words contained in a specific text.

Are Patient Linguistic Tones Associated with Mental Health and Perceived Clinician Empathy?

Musculoskeletal specialists have the expertise to distinguish between (1) symptoms that correspond well with observed pathophysiology and (2) disproportionate or incongruent symptoms that may suggest mental and social health opportunities. There is evidence that patient verbal and nonverbal communication can help with this discernment. This study carried this line of research one step further by addressing whether patient linguistic tones, as assessed with use of Linguistic Inquiry and Word Count (LIWC), are associated with symptoms of depression and health anxiety. We also sought associations between both patient and clinician linguistic tones and patient-perceived clinician empathy. A secondary analysis of transcripts of video and audio recordings of 109 adult patients seeking musculoskeletal specialty care was performed. Patients also completed questionnaires quantifying symptoms of depression (PROMIS [Patient-Reported Outcomes Measurement Information System] Depression computerized adaptive test), self-efficacy when in pain (Pain Self-Efficacy Questionnaire, 2-question version), symptoms of health anxiety (5-item Short Health Anxiety Inventory [SHAI-5]), and perceived clinician empathy (Jefferson Scale of Patient Perceptions of Physician Empathy [JSPPPE]). LIWC was used to detect the relative strength of various emotional tones, cognitive processes, and core drives and needs. Bivariate and multivariable regression analyses sought factors associated with symptoms of depression, symptoms of health anxiety, and patient perception of clinician empathy. With greater levels of depression, patients express less emotion overall as detected with use of computational linguistic analysis. After accounting for demographic variables, there were no specific linguistic tones associated with health anxiety and symptoms of depression. Stronger negative linguistic tones were associated with lower pain self-efficacy. Greater perceived clinician empathy was associated with more words spoken by the clinician and the patient, greater patient use of adjectives, lower prevalence of patient tones of "analytic," lower clinician tones of "social," and greater tones of "cause." Musculoskeletal specialists cannot depend on people experiencing symptoms of psychological distress to verbally express their feelings. Specialists may be more likely to identify important symptoms of psychological distress if they anticipate lower emotional expressiveness and are attentive to specific words, concepts, and mannerisms known to be associated with distress.

Sickle Cell Trait and Cognitive Function in African Americans: The Reasons for Geographic and Racial Differences in Stroke (REGARDS) Cohort

▪Background: Sickle cell anemia (SCA) has been associated with cognitive dysfunction. Increasing evidence suggests that some complications of SCA, such as kidney disease and venous thromboembolism, also affect those with sickle cell trait (SCT). Thus, SCT may not be a benign condition. Based on these findings, we hypothesized that SCT is a risk factor for cognitive function in African-Americans. We previously reported no association of SCT with cognitive impairment evaluated by a global screening test. Here we studied specific cognitive function measures.Methods: We studied African-American adults aged 45 and older from a national prospective cohort study of 30,239 white and black Americans; the REGARDS study. Participants were enrolled in 2003-7 and followed for up to 10 years. We collected extensive baseline risk factor data, and administered a cognitive battery every 2 years including tests of learning and memory (Word List Learning (WLL), Word List Recall (WLR)), semantic fluency by the Animal Naming test, and phonemic fluency by the Letter F test. WLL is the sum of words learned over 3 trials of immediate recall of 10 words (score ranges 0-30 words). WLR is the sum of words recalled after intervening questions (range 0-10 words). The Animal Naming score is the number of animals a participant can name within 1-minute and the Letter F score is the number of words beginning with the letter F that a participant can say within 1-minute. Participants included in this analysis were African-Americans without SCA or prebaseline stroke, who had SCT genotyping. Participants with baseline cognitive impairment by a global screening test were excluded. Mixed models were employed to assess the association of SCT with repeated measures of each test, adjusted for risk factors. Censoring occurred at the time of a stroke, death or withdrawal from the study.Results: There were 7,078 participants with at least 1 assessment of WLL and WLR who met inclusion criteria; their mean age was 63.4 years, 64% were women, and 517 had SCT. Those with SCT were more likely than those without to have hypertension (65% vs 60%; p=0.04), no alcohol use (75% vs 70%, p=0.03), and lower estimated glomerular filtration rate (eGFR) (86 vs 90 ml/min/1.73m2; p<0.0001). They were similar on other factors. The top panel of the figure shows that WLL and WLR changed little over time and there was no difference in scores by SCT status (adjusted p values shown). There were 7,296 participants included in the Animal Naming analysis and 5,946 for Letter F (differences due to delays in processing scores). The lower panel of the figure shows that performance on both tests worsened over time, with no difference by SCT status (adjusted p values shown).Conclusion: In this prospectively followed general population cohort of middle-aged and older African-Americans with longitudinal cognitive function testing, SCT was not associated with differences in cognitive functioning.Figure.

Extractive Text Summarization Models for Urdu Language

In the recent few years, a lot of advancement has been made in Urdu linguistics. There are many portals and news websites that are generating a huge amount of data every day. However, there is still no publicly available dataset nor any framework available for automatic Urdu extractive summary generation. In an automatic extractive summary generation, the sentences with the highest weights are given importance to be included in the summary. The sentence weight is computed by the sum of the weights of the words in the sentence. There are two famous approaches to compute the weight of the words in the English language: local weights (LW) approach and global weights (GW) approach. The sensitivity of the weights depends on the contents of the text, the one word may have different weights in a different article, known as LW based approach. Whereas, in the case of GW, the weights of the words are computed from the independent dataset, which implies the weights of all words remain the same in different articles. In the proposed framework, LW and GW based approaches are modeled for the Urdu language. The sentence weight method and the weighted term-frequency method are LW based approaches that compute the weights of the sentences by the sum of important words and the sum of frequencies of the important words, respectively. Whereas, vector space model (VSM) is GW based approach, that computes the weight of the words from the independent dataset, and then remain the same for all types of the text; GW is widely used in the English language for various applications such as information retrieval and text classification. The extractive summaries are generated by LW and GW based approaches and evaluated with ground-truth summaries that are obtained by the experts. The VSM is used as a baseline framework for sentence weighting. Experiments show that LW based approaches are better for extractive summary generation. The F-score of the sentence weight method and the weighted term-frequency method are 80% and 76%, respectively. The VSM achieved only 62% accuracy on the same dataset. Both, the datasets with ground-truth, and the code are made publicly available for the researchers.

Using Natural Language Processing and Sentiment Analysis to Augment Traditional User-Centered Design: Development and Usability Study.

BackgroundSarcopenia, defined as the age-associated loss of muscle mass and strength, can be effectively mitigated through resistance-based physical activity. With compliance at approximately 40% for home-based exercise prescriptions, implementing a remote sensing system would help patients and clinicians to better understand treatment progress and increase compliance. The inclusion of end users in the development of mobile apps for remote-sensing systems can ensure that they are both user friendly and facilitate compliance. With advancements in natural language processing (NLP), there is potential for these methods to be used with data collected through the user-centered design process.ObjectiveThis study aims to develop a mobile app for a novel device through a user-centered design process with both older adults and clinicians while exploring whether data collected through this process can be used in NLP and sentiment analysisMethodsThrough a user-centered design process, we conducted semistructured interviews during the development of a geriatric-friendly Bluetooth-connected resistance exercise band app. We interviewed patients and clinicians at weeks 0, 5, and 10 of the app development. Each semistructured interview consisted of heuristic evaluations, cognitive walkthroughs, and observations. We used the Bing sentiment library for a sentiment analysis of interview transcripts and then applied NLP-based latent Dirichlet allocation (LDA) topic modeling to identify differences and similarities in patient and clinician participant interviews. Sentiment was defined as the sum of positive and negative words (each word with a +1 or −1 value). To assess utility, we used quantitative assessment questionnaires—System Usability Scale (SUS) and Usefulness, Satisfaction, and Ease of use (USE). Finally, we used multivariate linear models—adjusting for age, sex, subject group (clinician vs patient), and development—to explore the association between sentiment analysis and SUS and USE outcomes.ResultsThe mean age of the 22 participants was 68 (SD 14) years, and 17 (77%) were female. The overall mean SUS and USE scores were 66.4 (SD 13.6) and 41.3 (SD 15.2), respectively. Both patients and clinicians provided valuable insights into the needs of older adults when designing and building an app. The mean positive-negative sentiment per sentence was 0.19 (SD 0.21) and 0.47 (SD 0.21) for patient and clinician interviews, respectively. We found a positive association with positive sentiment in an interview and SUS score (ß=1.38; 95% CI 0.37 to 2.39; P=.01). There was no significant association between sentiment and the USE score. The LDA analysis found no overlap between patients and clinicians in the 8 identified topics.ConclusionsInvolving patients and clinicians allowed us to design and build an app that is user friendly for older adults while supporting compliance. This is the first analysis using NLP and usability questionnaires in the quantification of user-centered design of technology for older adults.

Fusing depth and colour information for human action recognition

In recent years, human action recognition systems have been increasingly developed to support a wide range of application areas, such as surveillance, behaviour analysis, security, and many others. In particular, data fusion approaches that use depth and colour information (i.e., RGB-D data) seem to be particularly promising for recognizing large classes of human actions with a high level of accuracy. Anyway, existing data fusion approaches are mainly based on feature fusion strategies, which tend to suffer of some limitations, including the difficult of combining different feature types and the management of missing information. To address the two problems just reported, we propose an RGB-D data based human action recognition system supported by a decision fusion strategy. The system, starting from the well-known Joint Directors of Laboratories (JDL) data fusion model, analyses human actions separately for each channel (i.e., depth and colour). The actions are modelled as a sum of visual words by using the traditional Bag-of-Visual-Words (BoVW) model. Subsequently, on each channel, these actions are classified by using a multi-class Support Vector Machine (SVM) classifier. Finally, the classification results are fused by a Naive Bayes Combination (NBC) method. The effectiveness of the proposed system has been proven on the basis of three public datasets: UTKinect-Action3D, CAD-60, and LIRIS Human Activities. Experimental results, compared with key works of the current state-of-the-art, have shown that what we propose can be considered a concrete contribute to the action recognition field.

Book Review: Thieves of State

We underestimate corruption. These three words sum up the driving thesis of Sarah Chayes’ Thieves of State. In fact, we—including scholars, commentators and especially Western political and military leaders and advisers—underestimate almost every facet of corruption. We misread its pervasive extent and its networked, systemic nature. We fail to appreciate its crushing impact on those who suffer under its yoke. We downplay the sinister social, political, cultural, and even religious shifts it drives, and the way such dynamics fuel civil strife and armed conflict. And as a result of all of these underestimations, the international community (and the U.S. in particular) make catastrophic strategic miscalculations when engaging with struggling states like Iraq and Afghanistan.

Book Review: What Wars Leave Behind: The Faceless and the Forgotten, by J. Malcolm Garcia

J. Malcolm Garcia What Wars Leave Behind: The Faceless and Forgotten. Columbia: University of Missouri Press. 2014. 310 pp.News of war is mostly about soldiers-the official warriors who plunge into battle, fighting for what their country, their sect, their beliefs see as right and just. For most part, these stories come devoid of context related to battlegrounds. Yet once war is gone, a mass of rubble remains: citizens, infrastructures, daily lives all lost in a dark blur.What Wars Leave Behind is about that dark blur. Through 15 chapters divided into three parts-Conflict Zones, Lost and Gone, Home Bound-freelance journalist J. Malcolm Garcia provides powerful imagery of gritty hopelessness that shrouds all that is left behind. Through vivid snippets of conversations with locals and an insider's view of daily life in former war zones, he paints a montage of words akin to images created by an impressionist painter. The sum of words adds up to much more than words alone. Rarely does his assault of lived experience hold still for long, as Garcia moves from one bleak scenario to next.Clearly, Garcia's book is advocacy journalism, but it is not political advocacy. Instead, through his portraits and landscapes, Garcia demonstrates why human remnants of war beg for a saner, safer world. Much of narrative drives forward without theme sentences or specific arguments. This writing technique demands that reader draw a broader understanding by meditating on details until a larger message appears.Garcia became a journalist through an unconventional route-until age of 40, he carved out his career as a social worker. Then, in 1997, he began his journalism career as a beat reporter for The Kansas City Star, turning into what he calls the wandering scribe, four years later during his first overseas assignment in Afghanistan at dawn of post-9/11 era. That experience resulted in his first non-fiction narrative book, The Khaarijee: A Chronicle of Friendship and War in Kabul. As a freelance writer, Garcia has had his work appear in Virginia Quarterly Review, McSweeney's, and Mother Jones, among others. In a telling interview with The Investigative Fund, Garcia reflects on his reporting process and his note-taking approach that make writing of What Wars Leave Behind rich and alive.1In What Wars Leave Behind, Garcia takes reader through seven war-torn nations: Afghanistan, Chad, Egypt, Kosovo, Pakistan, Syria, and Turkey. The earliest writings come from 2004, most recent from 2013. Nearly all writings have been previously published, with six chapters based in Afghanistan and three from Pakistan. Some common themes emerge across these works: desperation, acceptance, corruption, fear, and greed.After spending time with Garcia's stories in What Wars Leave Behind, a feeling of paranoia began to swell-I had an urge to look over my shoulder, wondering, Is reality what we imagine or what we experience? In Syria, where impending doom mixed with family life,We retrace our steps to where we started. …

Language Impairment in Adolescents With Sydenham Chorea

BackgroundNeuropsychiatric comorbidities are frequent in Sydenham chorea. However, cognitive impairment in Sydenham chorea has not been sufficiently described. The objective of this study was to evaluate expressive and receptive language deficits in adolescents with Sydenham chorea. MethodsTwenty patients with Sydenham chorea were compared with 20 patients with rheumatic fever without chorea and 20 healthy controls. Participants were matched for age and gender. Participants were assessed with verbal fluency tasks (phonemic and semantic) and with verbal comprehension tasks (Token Test). Patients with Sydenham chorea were also assessed with the Universidade Federal de Minas Gerais Sydenham Chorea Rating Scale. ResultsPerformance in verbal fluency and in verbal comprehension tasks differed significantly (P < 0.01) among the three groups. Patients with Sydenham chorea performed significantly worse than healthy control group in phonemic and semantic verbal fluency tasks as well as in the Token Test. The group with rheumatic fever also performed worse than healthy controls in phonemic verbal fluency. Severity of motor signs in Sydenham chorea inversely correlated with performance in phonemic verbal fluency (words beginning with letter S, and total sum of words beginning with letters F, A, and S). ConclusionsAdolescents with Sydenham chorea show difficulties in verbal fluency and in verbal comprehension. Patients with rheumatic fever also have some degree of language impairment. Future studies must investigate language impairment in difference stages of Sydenham chorea (acute, persistent, and remission) and putative biological markers.

Industrialisation of the back-office function

Do more, safely and in less time. These few words sum up the challenge of industrialising back-office functions. Not so very long ago, in the last century, back-office functions involved paper processing and physical securities delivered via trucks. Today they comprise a virtual but very real world of electronic flows and processing of securities. Huge efforts in automation have been made, more or less continuously since the 1970s, supported by the implementation of standards, to achieve the industrialisation of the back office which has occurred in response to increased volumes in the general move towards globalisation and the reduction in time taken to process securities. These efforts, which are likely to continue, have led to restructuring and increased staff specialisation, which in turn offers real challenges to many organisations — both in terms of training and in keeping on board highly qualified specialists able to adapt themselves to a constantly changing environment and offer their clients tailor-made solutions in an industrialised environment.

Some Necessary Translation Methods during the Transference of a Meaningful Message from One Cultural Identity to Another

The standards of identity, culture, tradition, and history cannot be misunderstood by another identity if there is a real linguistic and extra-linguistic translation. The communication point between interlocutors who do not come from the same country and do not share the same culture, who do not have the same origin and consequently do not share the same customs, is in need for a translator. The object of this research paper is: The cultural transference like the linguistic transfer is an absolute requirement in the communication between two different identities. The meaning is not merely a sum of words, but an organic meaningful unity that is expressed in non-identical ways in different identities. The research questions in this paper are: Is it possible to make a point of communication between two different cultures? What are the methods that make this communication possible in order to make the transference of meaningful messages possible? DOI: 10.5901/jesr.2014.v4n3p119

Uncinate fasciculus microstructure and verbal episodic memory in amyotrophic lateral sclerosis: a diffusion tensor imaging and neuropsychological study

The present study evaluates the integrity of uncinate fasciculus (UF) and the association between UF microstructure and verbal episodic memory (as one of the cognitive functions linked to UF) in non-demented patients with amyotrophic lateral sclerosis (ALS) using diffusion tensor imaging (DTI). We studied 21 patients with ALS and 11 healthy, demographically-comparable volunteers. Fractional anisotropy, apparent diffusion coefficient, axial and radial diffusivity were the DTI metrics examined. Episodic memory was evaluated with Babcock Story Recall Test and Rey Auditory Verbal Learning Test (RAVLT) for patients; measures of immediate and delayed recall and retention for both tests and sum of words recalled through five learning trials for RAVLT were considered. Patients with ALS showed significant bilateral reduction of axial diffusivity in the UF as compared to controls. Furthermore, there were several significant relations between various DTI metrics (mostly in left hemisphere) and memory measures (specifically for the RAVLT). UF microstructural changes may contribute to ALS-related memory impairment, with word-list learning performance relying more upon the integrity of frontal and temporal connections than memory components associated with story recall.

Lexical Organization and Access: A Developmental Cognitive Approach to the Acquisition of Morphology

&lt;p&gt;&lt;em&gt;The present paper represents a further step in the work of Kahlaoui (2000) on lexical organization and access. It was argued in this paper that the distinction between regular and irregular morphology is counter cognitive as it deprives a good deal of the lexical elements from being processed via rule abstraction (Plunkett &amp;amp; Marchman, 1993) only because they are processed by minor rules (Mohanan, 1986). The lexicon is the modular mental component of a speaker's linguistic knowledge. It was also argued that the poor performance of dysphasic speakers on regular morphology is to be explained outside the non-natural and cognitively unwarranted distinction between regularity and irregularity. The lexicon is the sum of words – devoid of any internal structure -- known to the speaker. It was also argued that the set of word formation strategies generated/abstracted by the speaker in a developmental cognitive fashion constitutes his/her morphological system, which will be used for an automatic normal access to words. Automatic access is the normal access route via the central nervous system which is linguistically aware of the grammar it uses to access the modular the encapsulated lexicon. Access is performed through the strategy itself for both comprehension and production and happens in a non-modular fashion. Default – or emergency – access is performed in cases of accidental or mnemonic failure through a direct look-up procedure into the associative lexicon and through the central nervous system.&lt;/em&gt;&lt;/p&gt;

Bounded density shifts

AbstractWe consider subshifts of the full shift of bi-infinite sequences with alphabet $\{ 0, 1, \ldots , n- 1\} $ defined by not allowing the sum of finite words to exceed a value depending on its length. These shifts we call bounded density shifts. We study these shifts in detail and make a comparison on the similarities to but also differences from the well-known $\beta $-shifts.

Der frühe expressive Wortschatzumfang simultan mehrsprachig aufwachsender Kinder - ein diagnostisch relevantes Kriterium?

Bilingual young children's early expressive vocabulary size and its composition (as one domain of the language development) should be examined to find out whether children with a risk for delayed language development may be identified in this way. 30 bilingual kindergarten infants from Berlin (with simultaneous language acquisition; second language German) and 30 monolingual German infants from the greater areas of Stuttgart and Heidelberg were pair matched (mean chronological age 22.5 [SD 3.1] months; min 16; max 26). The German expressive vocabulary checklist Elternfragebogen zur Wort-schatzentwicklung im frühen Kindesalter (ELAN; Bockmann & Kiese-Himmel, 2006) was filled out by all parents. In addition, parents of bilingual infants completed the adaption of the German vocabulary checklist Sprachbeurteilung durch Eltern (SBE-2-KT; v. Suchodoletz & Sachse, 2008) for the second mother tongue. The monolinguals' word sum in the ELAN (145.7; SD 75.8) differed significantly (p=0.001) from the bilinguals' word sum (78.3; SD 78.9 words). In contrast, bilinguals did not significantly differ in their overall expressive vocabulary size (ELAN+SBE-2-KT: 101.2; SD 77.0 words) from their monolingual counterparts (ELAN). Because bilinguals had a similar sized overall early vocabulary (both languages) like monolingual German-learning infants, the diagnostic criterion to identify late talkers with 24 months of age (less than 50 German words and no word combinations) should not be applied to bilingually infants with simultaneously double language acquisition.

Praat소프트웨어 프로그램을 이용한 영어모음 길이에 관한 실험적 연구

The purpose of this experimental study is to investigate and compare the vowel lengths of the English diphthongs, /e?/ and /a?/, and the front low vowel /ae/ among English-speaking natives with Korean college students using the Praat software program. To do this English sentences were uttered and recorded by twelve subjects, six Korean subjects and six English-speaking native subjects. All the subjects are female and their age ranges from 23 to 35. Acoustic features(duration) were measured from a sound spectrogram with the help of the Praat software program and analyzed through statistical analysis. Results showed that the vowel lengths of the English diphthongs and the front low vowel between native English speakers and Korean collegians were different. In the pronunciation of the diphthongs /e?/ and /a?/, Korean subjects pronounced longer than native subjects did, but the difference was not significant. However, in the pronunciation of the English front low vowel /ae/, native subjects pronounced significantly longer than Korean subjects did. From the data of the overall sum of words and vowels between the two subject groups, we were able to find out that the differences of lengths of both the three words and the two diphthongs /e?/ and /a?/ were not significant, but those of / ae / were significant.
