    2008-09-01

    Full Text Available Twenty listeners were exposed to spoken and sung passages in English produced by three trained vocalists. Passages included representative words extracted from a large database of vocal lyrics, including both popular and classical repertoires. Target words were set within spoken or sung carrier phrases. Sung carrier phrases were selected from classical vocal melodies. Roughly a quarter of all words sung by an unaccompanied soloist were misheard. Sung passages showed a seven-fold decrease in intelligibility compared with their spoken counterparts. The perceptual mistakes occurring with vowels replicate previous studies showing the centralization of vowels. Significant confusions are also evident for consonants, especially voiced stops and nasals.

    Previous studies have suggested that presenting to-be-memorised lyrics in a singing mode, instead of a speaking mode, may facilitate learning and retention in normal adults. In this study, seven healthy older adults and eight participants with mild Alzheimer's disease (AD) learned and memorised lyrics that were either sung or spoken. We measured the percentage of words recalled from these lyrics immediately and after 10 minutes. Moreover, in AD participants, we tested the effect of successive learning episodes for one spoken and one sung excerpt, as well as long-term retention after a four week delay. Sung conditions did not influence lyrics recall in immediate recall but increased delayed recall for both groups. In AD, learning slopes for sung and spoken lyrics did not show a significant difference across successive learning episodes. However, sung lyrics showed a slight advantage over spoken ones after a four week delay. These results suggest that singing may increase the load of initial learning but improve long-term retention of newly acquired verbal information. We further propose some recommendations on how to maximise these effects and make them relevant for therapeutic applications.

  7. Representation and alignment of sung queries for music information retrieval

    Adams, Norman H.; Wakefield, Gregory H.

    2005-09-01

    The pursuit of robust and rapid query-by-humming systems, which search melodic databases using sung queries, is a common theme in music information retrieval. The retrieval aspect of this database problem has received considerable attention, whereas the front-end processing of sung queries and the data structure to represent melodies has been based on musical intuition and historical momentum. The present work explores three time series representations for sung queries: a sequence of notes, a ``smooth'' pitch contour, and a sequence of pitch histograms. The performance of the three representations is compared using a collection of naturally sung queries. It is found that the most robust performance is achieved by the representation with highest dimension, the smooth pitch contour, but that this representation presents a formidable computational burden. For all three representations, it is necessary to align the query and target in order to achieve robust performance. The computational cost of the alignment is quadratic, hence it is necessary to keep the dimension small for rapid retrieval. Accordingly, iterative deepening is employed to achieve both robust performance and rapid retrieval. Finally, the conventional iterative framework is expanded to adapt the alignment constraints based on previous iterations, further expediting retrieval without degrading performance.

  8. Ethical modernization: research misconduct and research ethics reforms in Korea following the Hwang affair.

    2013-06-01

    The Hwang affair, a dramatic and far reaching instance of scientific fraud, shocked the world. This collective national failure prompted various organizations in Korea, including universities, regulatory agencies, and research associations, to engage in self-criticism and research ethics reforms. This paper aims, first, to document and review research misconduct perpetrated by Hwang and members of his research team, with particular attention to the agencies that failed to regulate and then supervise Hwang's research. The paper then examines the research ethics reforms introduced in the wake of this international scandal. After reviewing American and European research governance structures and policies, policy makers developed a mixed model mindful of its Korean context. The third part of the paper examines how research ethics reform is proactive (a response to shocking scientific misconduct and ensuing external criticism from the press and society) as well as reactive (identification of and adherence to national or international ethics standards). The last part deals with Korean society's response to the Hwang affair, which had the effect of a moral atomic bomb and has led to broad ethical reform in Korean society. We conceptualize this change as ethical modernization, through which the Korean public corrects the failures of a growth-oriented economic model for social progress, and attempts to create a more trustworthy and ethical society.

    Singing is universal, and understanding sung words is thought to be important for many listeners' enjoyment of vocal and choral music. However, this is not a trivial task, and sung text intelligibility is probably affected by many factors. A survey of musicians was undertaken to identify the factors believed to have most impact on intelligibility, and to assess the importance of understanding sung words in familiar and unfamiliar languages. A total of 143 professional and amateur musicians, including singers, singing teachers, and regular listeners to vocal music, provided 394 statements yielding 851 references to one or more of 43 discrete factors in four categories: performer-related, listener-related, environment-related and words/music-related. The factors mentioned most frequently in each of the four categories were, respectively: diction; hearing ability; acoustic; and genre. In more than a third of references, the extent to which sung text is intelligible was attributed to the performer. Over 60% of respondents rated the ability to understand words in familiar languages as "very important," but only 17% when the text was in an unfamiliar language. Professional musicians (47% of the sample) rated the importance of understanding in both familiar and unfamiliar languages significantly higher than amateurs but listed fewer factors overall and fewer listener-related factors. The more important the respondents rated understanding, the more performer-related and environment-related factors they tended to list. There were no significant differences between the responses of those who teach singing and those who do not. Enhancing sung text intelligibility is thus perceived to be within the singer's control, at least to some extent, but there are also many factors outside their control. Empirical research is needed to explore some of these factors in greater depth, and has the potential to inform pedagogy for singers, composers, and choral directors.

    Full Text Available Acupuncture has fairly good weight-reducing effect in treating simple obesity due to the neuroendocrine regulation. In this study, the anti-obesity effects of herbal acupuncture (HA with Sang-hwang (Phellinus linteus at Fuai (SP16 were investigated in the rat fed on high-fat (HF diet. Sang-hwang mushroom has been proven to have anti-carcinogenic effects and Sang-hwang extracts are highly effective in treatment and preventive treatment of AIDS, diabetes and high blood-pressure. To determine whether the Sang-hwang herbal acupuncture may have the anti-obesity effect, male Sprague-Dawley (4-wk-old rats were fed a HF diet for 5 wk, which produced significant weight gain compared to rats were fed a normal diet, and then herbal acupuncture were treated for 3 wk in HF diet group. The body weight, food consumption, food effeciency ratio (FER, body fat mass, plasma nitric oxide (NO were investigated in rats fed on normal diet, HF diet, and HF diet with HA (HF-diet-HA groups. NO has been proposed to be involved in the regulation of food intake. In addition, the expression of appetite peptides such as orexigenic peptide neuropeptide Y (NPY and the anorectic peptide cholecystokinin (CCK were observed in the hypothalamus. HF-HA group reduced body weight gain, FER, body fat contents and NO concentration compared to HF diet group. The expression of NPY was reduced in arcuate nucleus (ARC, and CCK was increased in the paraventricular nucleus (PVN after treatment of HA. In conclusion, Sang-hwang HA reduced adipocity, plasma NO and hypothalamic NPY, but increased CCK expression in the HF diet-induced obesity rat, therefore HA may have anti-obesity action through regulating body weight and appetite peptide of the central nervous system.

    Abstract The fluviatile terrace deposits of Khok Sung, Nakhon Ratchasima province, have yielded more than one thousand fossils, making this the richest Pleistocene vertebrate fauna of Thailand. The excellent preservation of the specimens allows precise characterization of the faunal composition. The mammalian fauna consists of fifteen species in thirteen genera, including a primate, a canid, a hyaenid, proboscideans, rhinoceroses, a suid, cervids, and bovids. Most species correspond to living taxa but globally (Stegodon cf. orientalis) and locally (Crocuta crocuta ultima, Rhinoceros unicornis, Sus barbatus, and Axis axis) extinct taxa were also present. The identification of Axis axis in Khok Sung, a chital currently restricted to the Indian Subcontinent, represents the first record of the species in Southeast Asia. Three reptilian taxa: Crocodylus cf. siamensis, Python sp., and Varanus sp., are also identified. Faunal correlations with other Southeast Asian sites suggest a late Middle to early Late Pleistocene age for the Khok Sung assemblage. However, the Khok Sung mammalian fauna is most similar to that of Thum Wiman Nakin, dated to older than 169 ka. The Khok Sung large mammal assemblage mostly comprises mainland Southeast Asian taxa that migrated to Java during the latest Middle Pleistocene, supporting the hypothesis that Thailand was a biogeographic pathway for the Sino-Malayan migration event from South China to Java.

  19. Words and melody are intertwined in perception of sung words: EEG and behavioral evidence.

    Directory of Open Access Journals (Sweden)

    Reyna L Gordon

    Full Text Available Language and music, two of the most unique human cognitive abilities, are combined in song, rendering it an ecological model for comparing speech and music cognition. The present study was designed to determine whether words and melodies in song are processed interactively or independently, and to examine the influence of attention on the processing of words and melodies in song. Event-Related brain Potentials (ERPs and behavioral data were recorded while non-musicians listened to pairs of sung words (prime and target presented in four experimental conditions: same word, same melody; same word, different melody; different word, same melody; different word, different melody. Participants were asked to attend to either the words or the melody, and to perform a same/different task. In both attentional tasks, different word targets elicited an N400 component, as predicted based on previous results. Most interestingly, different melodies (sung with the same word elicited an N400 component followed by a late positive component. Finally, ERP and behavioral data converged in showing interactions between the linguistic and melodic dimensions of sung words. The finding that the N400 effect, a well-established marker of semantic processing, was modulated by musical melody in song suggests that variations in musical features affect word processing in sung language. Implications of the interactions between words and melody are discussed in light of evidence for shared neural processing resources between the phonological/semantic aspects of language and the melodic/harmonic aspects of music.

  20. The effect of sung speech on socio-communicative responsiveness in children with autism spectrum disorders.

    There is emerging evidence to demonstrate the efficacy of music-based interventions for improving social functioning in children with Autism Spectrum Disorders (ASD). While this evidence lends some support in favor of using song over spoken directives in facilitating engagement and receptive intervention in ASD, there has been little research that has investigated the efficacy of such stimuli on socio-communicative responsiveness measures. Here, we present preliminary results from a pilot study which tested whether sung instruction, as compared to spoken directives, could elicit greater number of socio-communicative behaviors in young children with ASD. Using an adapted single-subject design, three children between the ages of 3 and 4 years, participated in a programme consisting of 18 sessions, of which 9 were delivered with spoken directives and 9 with sung. Sessions were counterbalanced and randomized for three play activities-block matching, picture matching and clay play. All sessions were video-recorded for post-hoc observational coding of three behavioral metrics which included performance, frequency of social gesture and eye contact. Analysis of the videos by two independent raters indicated increased socio-communicative responsiveness in terms of frequency of social gesture as well as eye contact during sung compared to spoken conditions, across all participants. Our findings suggest that sung directives may play a useful role in engaging children with ASD and also serve as an effective interventional medium to enhance socio-communicative responsiveness.

  4. The Identification of High-pitched Sung Vowels in Sense and Nonsense Words by Professional Singers and Untrained Listeners.

    Science.gov (United States)

    Deme, Andrea

    2017-03-01

    High-pitched sung vowels may be considered phonetically "underspecified" because of (i) the tuning of the F 1 to the f 0 accompanying pitch raising and (ii) the wide harmonic spacing of the voice source resulting in the undersampling of the vocal tract transfer function. Therefore, sung vowel intelligibility is expected to decrease as the f 0 increases. Based on the literature of speech perception, it is often suggested that sung vowels are better perceived if uttered in consonantal (CVC) context than in isolation even at high f 0 . The results for singing, however, are contradictory. In the present study, we further investigate this question. We compare vowel identification in sense and nonsense CVC sequences and show that the positive effect of the context disappears if the number of legal choices in a perception test is similar in both conditions, meaning that any positive effect of the CVC context may only stem from the smaller number of possible responses, i.e., from higher probabilities. Additionally, it is also tested whether the training in production (i.e., singing training) may also lead to a perceptual advantage of the singers over nonsingers in the identification of high-pitched sung vowels. The results show no advantage of this kind. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    2018-01-01

    This study examined music and speech perception in normal-hearing children with some or no musical training. Thirty children (mean age = 11.3 years), 15 with and 15 without formal music training participated in the study. Music perception was measured using a melodic contour identification (MCI) task; stimuli were a piano sample or sung speech with a fixed timbre (same word for each note) or a mixed timbre (different words for each note). Speech perception was measured in quiet and in steady noise using a matrix-styled sentence recognition task; stimuli were naturally intonated speech or sung speech with a fixed pitch (same note for each word) or a mixed pitch (different notes for each word). Significant musician advantages were observed for MCI and speech in noise but not for speech in quiet. MCI performance was significantly poorer with the mixed timbre stimuli. Speech performance in noise was significantly poorer with the fixed or mixed pitch stimuli than with spoken speech. Across all subjects, age at testing and MCI performance were significantly correlated with speech performance in noise. MCI and speech performance in quiet was significantly poorer for children than for adults from a related study using the same stimuli and tasks; speech performance in noise was significantly poorer for young than for older children. Long-term music training appeared to benefit melodic pitch perception and speech understanding in noise in these pediatric listeners.

    2009-05-01

    We examine the argumentative structure of Hwang et al.’s (2004) paper about human somatic cell nuclear transfer (SCNT, or ‘therapeutic cloning’), contrasted with four Journalistic Reported Versions (JRV) of it, and with students’ summaries of one JRV. As the evaluation of evidence is one of the critical features of argumentation (Jiménez-Aleixandre 2008), the analysis focuses on the use of evidence, drawing from instruments to analyze written argumentation (Kelly et al. 2008) and from studies about the structure of empirical research reports (Swales 2001). The objectives are: 1) To examine the use of evidence and the argumentative structure of Hwang et al.’s Science, 303: 1669-1674 (2004) original paper in terms of the criteria: a) pertinence of the evidence presented to the claims; b) sufficiency of the evidence for the purpose of supporting the claims; and c) coordination of the evidence across epistemic levels. 2) To explore how the structure of Hwang’s paper translates into the JRV and into university students’ perceptions about the evidence supporting the claims. The argumentative structure of Hwang’s paper is such that its apparently ostensible main claim about NT constitutes a justification for a second claim about its therapeutic applications, for which no evidence is offered. However, this second claim receives prominent treatment in the JRV and in the students’ summaries. Implications for promoting critical reading in the classroom are discussed.

  8. Poor neuro-motor tuning of the human larynx: a comparison of sung and whistled pitch imitation

    Science.gov (United States)

    Johnson, Joseph F.; Kotz, Sonja A.

    2018-01-01

    Vocal imitation is a hallmark of human communication that underlies the capacity to learn to speak and sing. Even so, poor vocal imitation abilities are surprisingly common in the general population and even expert vocalists cannot match the precision of a musical instrument. Although humans have evolved a greater degree of control over the laryngeal muscles that govern voice production, this ability may be underdeveloped compared with control over the articulatory muscles, such as the tongue and lips, volitional control of which emerged earlier in primate evolution. Human participants imitated simple melodies by either singing (i.e. producing pitch with the larynx) or whistling (i.e. producing pitch with the lips and tongue). Sung notes were systematically biased towards each individual's habitual pitch, which we hypothesize may act to conserve muscular effort. Furthermore, while participants who sung more precisely also whistled more precisely, sung imitations were less precise than whistled imitations. The laryngeal muscles that control voice production are under less precise control than the oral muscles that are involved in whistling. This imprecision may be due to the relatively recent evolution of volitional laryngeal-motor control in humans, which may be tuned just well enough for the coarse modulation of vocal-pitch in speech.

    2009-12-01

    Full Text Available With the emergence of research on real-time visual feedback to supplement vocal pedagogy, the utilization of technology in the world of music is now seen to accelerate skills learning and enhance cognitive development. The researchers of this project aim to further analyze vowel intelligibility and develop software applications intended to be used not only by professional singers but also by individuals who wish to improve their singing capability. Data in the form of sung vowels and song pieces were obtained from 46 singers. A Listening Test was then conducted on these samples to obtain the ground truth for vowel classification based on human perception. Simulation of the human auditory perception of sung Filipino vowels was performed using formant frequencies and Mel-frequency cepstral coefficients as feature vector inputs to a two-stage Discriminant Analysis classifier. The setup resulted in an over-all Training Set accuracy of 89.4% and an over-all Test Set accuracy of 90.9%. The accuracy of the classifier, measured in terms of the correspondence of vowel classifications obtained from the classifier with the results of the Listening Test, reached 92.3%. Using information obtained from the classifier, offline and online/real-time software applications were developed. The main application features include the display of the spectral envelope and spectrogram, pitch and vibrato analysis and direct feedback on the classification of the sung vowel. These features were recommended by singers who were surveyed and were incorporated in the applications to aid singers to adjust formant locations, directly determine listener’s perception of sung vowels, perform modeling effectively and carry out vowel migration.

    Full Text Available In der methodischen Literatur zu qualitativen Interviews wird als Standardverfahren oft die Aufzeichnung mit einem Aufnahmegerät und anschließende wortgetreue Verschriftlichung (Transkription empfohlen. Protokolle werden als Mittel der Interviewdokumentation zumeist als zweitbeste Lösung für den Fall dargestellt, dass Mitschnitte nicht möglich sind. Diese Position stellen wir in diesem Beitrag aufgrund theoretischer Überlegungen und empirischer Erfahrungen infrage. Vor- und Nachteile der Dokumentationsformen "Audiomitschnitt + Transkription" und "Notizen + Protokollierung" werden systematisch gegenübergestellt. Anschließend wird anhand von zwei Studien exemplarisch verdeutlicht, dass die Protokollierung die beste Lösung zur Dokumentation der Interviewdaten sein kann. In beiden Studien wurden in Interviews sensible Themen behandelt und die Erhebung grundlegender Informationen über Prozesse und Routinen bezweckt. Grundsätzlich kann Protokollierung angezeigt sein, wenn weniger die Interpretation des Gesagten als vielmehr dessen Intention im Fokus der Forschung ist. Außerdem sollte eine Protokollierung erwogen werden, wenn eine Aufnahme besonders interessante InterviewpartnerInnen von der Teilnahme abhalten oder ein offenes Gespräch verhindern könnte. Mit diesem Beitrag wollen wir zu einer Auseinandersetzung darüber anregen, wann Protokollieren angemessen ist und wie es methodisch angelegt sein sollte.

    Full Text Available Any resource of high value and relevance to rural livelihoods is at risk of overexploitation. The anthropogenic pressure on the caterpillar fungus, Ophiocordyceps sinensis (Berk. G.H. Sung, J.M. Sung, Hywel-Jones & Spatafora 2007, commonly referred to as yartsa gunbu, is intense, especially given the absence of traditional sustainable collection techniques. Stable harvests are the result of 2 factors: more people searching more intensely and extensively and the ongoing discovery of new areas for harvest. Increasing international demand and prices (presently around US$ 20,000 per kg have resulted not just in overexploitation but also in the degradation of the fungus’s habitat, thus endangering its future viability. This article reports on a rapid vulnerability assessment involving 2511 harvesters in 9 broad study sites and 110 villages in the Pithoragarh district in Uttarakhand state, India, in the central Himalaya, and recommends ways to lessen the pressure on this valuable species.

  14. Perceptions on climate change and its impact on livelihoods in Hwange district, Zimbabwe

    Full Text Available This study investigated perceptions of rural communities on climate change and its impacts on livelihoods. The research was conducted in the semi-arid Hwange district in Matebelel and North province of Zimbabwe. The perceptions were compared with empirical evidence from climatic studies on trends on temperature and rainfall, and impacts on livelihoods in the country and region. The findings from the current study are generally in agreement with those of other studies that indicate changes in the climate, especially in terms of rainfall. This largely applies to short-term periods; however, for long-term periods it is difficult to accurately relate rural community perceptions to changes in rainfall over time. Despite perceived changes and impacts of climate change on local livelihood activities, mainly agriculture, there are multiple stressors that the communities face which also affect their livelihoods. Further evidence-based research is required to disentangle climate change impacts on livelihoods, including livelihood impacts arising from interactions of climate and non-climatic factors.

    2001-07-01

    Full Text Available Spotted hyaena Crocuta crocuta are known to be opportunists and to have a varied diet including mammals, reptiles and birds. Prey most often hunted are medium sized ungulates but spotted hyaenas will on occasion take larger species such as giraffe Giraffa camelopardalis and zebra Equus burchellii. They are also known to hunt whichever species are most abundant and will vary their prey seasonally. In this study spotted hyaenas were observed to take an unusual prey species in the form of elephant calves (Loxodonta africana. On a number of occasions hyaenas were observed feeding on or killing newborn and very young elephant calves. These observations were made whilst the authors were conducting research on spotted hyaena ecology in the woodlands of Hwange National Park, Zimbabwe and were made during the dry season between September and November 1999.

    Phonation onset is important in the maintenance of healthy vocal production for speech and singing. The purpose of this preliminary study was to examine differences in vocal fold vibratory behavior between sung and spoken phonation onset gestures. Given the greater degree of precision required for the abrupt onset sung gestures, we hypothesize that differences exist in the timing and coordination of the vocal fold adductory gesture with the onset of vocal fold vibration. Staccato and German (a modified glottal plosive, so named for its occurrence in German classical singing) onset gestures were compared with breathy, normal, and hard onset gestures, using high-speed digital imaging. Samples were obtained from two subjects with no history of voice disorders (a female trained singer and a male nonsinger). Simultaneous capture of acoustical data confirmed the distinction among gestures. Image data were compared for glottal area configurations, degree of adductory positioning, number of small-amplitude prephonatory oscillations (PPOs), and timing of onset gesture events, the latter marked by maximum vocal fold abduction, maximum adduction, beginning of PPOs, and beginning of steady-state oscillation. Results reveal closer adductory positioning of the vocal folds for the staccato and German gestures. The data also suggest a direct relationship between the degree of adductory positioning and the number of PPOs. Results for the timing of onset gesture events suggest a relationship between discrete adductory positioning and more evenly spaced PPOs. By contrast, the overlapping of prephonatory adductory positioning with vibration onset revealed more unevenly spaced PPOs. This may support an existing hypothesis that less well-defined boundaries interfere with normal modes of vibration of the vocal fold tissue. Copyright © 2012 The Voice Foundation.

    Full Text Available Objectives : To investigate the effect of Ga-mee-Gwui-ryong-tang herbal acupuncture (GR-HA at GB39 and ST36 and the effect of Yuk-mee ji-hwang-tang herbal acupuncture (YM-HA at GB39 and KI10 on growth in mice. Methods : Mice were divided into 7 groups(n=10 ; saline-ST36, saline-GB39, saline-KI10, GR-HA-ST36 group treated with GR-HA at right ST36, GR-HA-GB39 group treated with GR-HA at right GB39, YM-HA-GB39 group treated with YM-HA at right GB39, YM-HA-KI10 group treated with YM-HA at right KI10. Saline-ST36 group, saline-GB39 group and saline-KI10 group were injected with saline at right ST36, GB39, KI10 respectively. Saline injection and HA were performed 3 times a week for 18 days. The length(total height, body length and tail length, weight and the protein efficiency ratio were measured as well as IGF-1 level in serum. Results : 1. GR-HA at GB39 and GR-HA at ST36 promoted growth in weight, tail length and total height but there was no statistical significance. 2. GR-HA at GB39 significantly promoted protein efficiency on the 14th day and GR-HA at ST36 on the 3rd day. 3. GR-HA at GB39 significantly increased serum IGF-1. GR-HA at ST36 increased IGF-1 slightly but with no statistical significance. 4. YM-HA at GB39 and YM-HA at KI10 promoted growth in weight, height, tail length and total height but there was no statistical relevance. 5. YM-HA at GB39 and YM-HA at KI10 significantly promoted protein efficiency on the 14th day. 6. YM-HA at GB39 and YM-HA at KI10 significantly increased serum IGF-1. Serum IGF-1 level of YM-HA-KI10 group was significantly higher than that of YM-HA-GB39 group. 7. Serum IGF-1 level of GR-HA-GB39 group was significantly higher than that of YM-HA-GB39 group. Conclusions : GR-HA and YM-HA both may promote growth. This study suggests that herbal acupuncture at GB39 is more effective with Gwui-ryong-tang than Yuk-mee ji-hwang-tang to promote growth. It also suggests that Yuk-mee ji-hwang-tang herbal acupuncture is more

    2009-01-01

    We examine whether the current regulatory regime instituted in South Korea and the United States would have prevented Hwang's potential transgressions in oocyte procurement for somatic cell nuclear transfer, we compare the general aspects and oversight framework of the Bioethics and Biosafety Act in South Korea and the US National Academies' Guidelines for Human Embryonic Stem Cell Research, and apply the relevant provisions and recommendations to each transgression. We conclude that the Act would institute centralized oversight under governmental auspices while the Guidelines recommend politically-independent, decentralized oversight bodies including a special review body for human embryonic stem cell research at an institutional level and that the Guidelines would have provided more vigorous protection for the women who had undergone oocyte procurement for Hwang's research than the Act. We also suggest additional regulations to protect those who provide oocytes for research in South Korea.

    2016-04-01

    Full Text Available This paper considers James McBride’s novel Song Yet Sung through multiple lenses – Bakhtin’s Carnivalesque, magic realism and performativity as it relates to race and gender identities. It is considered how the character of the “Dreamer” can be read clinically as suffering the sequelae of a traumatic brain injury. Her symptoms, which include future hallucinations or prophecies, can be read as neurological symptoms of her multiple head injuries documented in the novel. Connected to this reading, the influence of magic realism is considered, particularly as it relates to the natural imagery and symbolism in the novel. The importance of birds, in particular, is considered. Carnivalesque as conceptualized by Bakhtin is also considered in the context of “magical” thinking and reading, and its connections to social subversion; this is considered in relation to the era of slavery, its legacy, and associated issues of gender and race. Keywords: Carnivalesque, Magic Realism, Prophecy, Gender Performance, Racial Performativity, Identity Performance

    Full Text Available Abstract Background Gyejibongnyeong-hwan (GJBNH is one of the most popular Korean medicine formulas for menstrual pain of dysmenorrhea. The concept of blood stagnation in Korean medicine is considered the main factor of causing abdominal pain, or cramps, during menstrual periods. To treat the symptoms, GJBNH is used to fluidify the stagnated blood and induce the blood flow to be smooth, reducing pain as the result. The purpose of this trial is to identify the efficacy of GJBNH in dysmenorrhea caused by blood stagnation. Methods This study is a multi-centre, randomised, double-blind, controlled trial with two parallel arms: the group taking GJBNH and the group taking placebo. 100 patients (women from age 18 to 35 will be enrolled to the trial. Through randomization 50 patients will be in experiment arm, and the other 50 patients will be in control arm. At the second visit (baseline, all participants who were already screened that they fulfil both the inclusion and the exclusion criteria will be randomised into two groups. Each group will take the intervention three times per day during two menstrual cycles. After the treatment for two cycles, each patient will be followed up during their 3rd, 4th and 5th menstrual cycles. From the screening (Visit 1 through the second follow-up (Visit 6 the entire process will take 25 weeks. Discussion This trial will provide evidence for the effectiveness of GJBNH in treating periodical pain due to dysmenorrhea that is caused by blood stagnation. The primary outcome between the two groups will be measured by changes in the Visual Analogue Score (VAS of pain. The secondary outcome will be measured by the Blood Stagnation Scale, the Short-form McGill questionnaire and the COX menstrual symptom scale. Analysis of covariance (ANCOVA and repeated measured ANOVA will be used to analyze the data analysis. Trial registration Current Controlled Trials: ISRCTN30426947

    Singing is as natural as speaking for humans. Increasing evidence shows that the layman can carry a tune (e.g., when asked to sing a well-known song or to imitate single pitches, intervals and short melodies). Yet, important individual differences exist in the general population with regard to singing proficiency. Some individuals are particularly inaccurate or imprecise in producing or imitating pitch information (poor-pitch singers), thus showing a variety of singing phenotypes. Unfortunately, so far there is not a standard set of tasks for assessing singing proficiency in the general population, allowing to uncover and characterize individual profiles of poor-pitch singing. Different tasks and analysis methods are typically used in various experiments, making the comparison of the results across studies arduous. To fill this gap we propose here a new tool for assessing singing proficiency (the Sung Performance Battery, SPB). The SPB starts from the assessment of participants' vocal range followed by five tasks: (1) single-pitch matching, (2) pitch-interval matching, (3) novel-melody matching, (4) singing from memory of familiar melodies (with lyrics and on a syllable), and (5) singing of familiar melodies (with lyrics and on a syllable) at a slow tempo indicated by a metronome. Data analysis via acoustical methods provides objective measures of pitch accuracy and precision in terms of absolute and relative pitch. The SPB has been tested in a group of 50 occasional singers. The results indicate that the battery is useful for characterizing proficient singing and for detecting cases of inaccurate and/or imprecise singing. PMID:24151475

Missionaries built schools and hospitals and effectively used them for evangelism. In the 20th century when Social Gospel Movement was expanding, medical work has been recognized as a significant mission service in and by itself. This article reviewed the construction and characteristics of missions work conducted by Canadian Presbytery; missionary doctors and Korean doctors who worked at the mission hospitals; why the missionary medical work had to stop; and career paths taken by Korean doctors upon liberation from Japanese occupation. The Canadian Presbytery missionaries, unlike other denomination missionaries, were rather critical of Imperial Japan, but supportive towards Koreans.

Thus, the aim of this study was to compare the detailed in vivo toxicity of Cu NPs and cupric ions (CuCl2; Cu ions after a single oral dose. We determined the physicochemical characteristics of Cu NPs, including morphology, hydrodynamic size, zeta potential, and dissolution in gastric (pH 1.5, vehicle (pH 6.5, and intestinal (pH 7.8 conditions. We also evaluated the kinetics of Cu following a single equivalent dose (500 mg/kg of Cu NPs and Cu ions. Cu NPs had highest dissolution (84.5% only in gastric conditions when compared with complete dissolution of Cu ions under various physiological milieus. Kinetic analysis revealed that highest Cu levels in blood and tested organs of Cu NP-treated rats were 15%–25% lower than that of Cu ions. Similar to the case of Cu ions, Cu levels in the tested organs (especially liver, kidney, and spleen of Cu NP-treated rats increased significantly when compared with the vehicle control. However, delay in reaching the highest level and biopersistence of Cu were observed in the blood and tested organs of Cu NP-treated rats compared with Cu ions. Extremely high levels of Cu in feces indicated that unabsorbed Cu NPs or absorbed Cu ions were predominantly eliminated through liver/feces. Cu NPs exerted apparent toxicological effects at higher dose levels compared with Cu ions and showed sex-dependent differences in mortality, biochemistry, and

    Full Text Available In dry biomes, spatio-temporal variation in surface water resource stocks is pervasive, with unknown effects on the ranging behaviour of large predators. This study assessed the effect of spatial variation in surface water resources on the ranging behaviour of the African wild dog (Lycaon pictus. We analyzed data for 1992 (dry year with 20 water points and 2000 (wet year with 30 water points against presence-only data for five packs of L. pictus in a part of Hwange National Park and adjacent smallholder communal farming areas in western Zimbabwe. Modelling the potential habitat for L. pictus using Maxent with distance from water points (Dw and Normalized Difference Vegetation Index (NDVI as predictor variables was successful for 2000 (AUC = 0.793 but not successful for 1992 (AUC = 0.423, with L. pictus probability of occurrence near water points being more for year 2000 than for year 1992. The predicted L. pictus range was wider in 1992 (~13888.1 km2 than in 2000 (~958.4 km2 (Test of Proportions, χ2 = 124.52, df = 1, P = 0.00. Using the 2nd order Multitype Nearest Neighbour Distance Function (Gcross, we also observed significant attraction between L. pictus and water points within only ~1km radius for 1992 but up to ~8km radius for 2000. Our study reinforced the notion that surface water resources attract wild dogs in the savannahs but paradoxically less so when water resources are scarce. In particular, our study furthers current understanding of the effects of changing water availability regimes on the endangered L. pictus, providing evidence that the endangered predator's home range encroaches into potential ecological traps (i.e., smallholder communal farming areas when water resources are scarce.

    2018-01-01

    Full Text Available This study investigates the possibilities of fostering learning based on differences in recall and comprehension after learning with texts which were presented in one of three modalities: either in a spoken, written, or sung version. All three texts differ regarding their processing, especially when considering working memory. Overall, we assume the best recall performance after learning with the written text and the best comprehension performance after learning with the sung text, respectively, compared to both other text modalities. We also analyzed whether the melody of the sung material functions as a mnemonic aid for the learners in the sung text condition. If melody and text of the sung version are closely linked, presentation of the melody during the post-test phase could foster text retrieval. 108 students either learned from a sung text performed by a professional singer, a printed text, or the same text read out loud. Half of the participants worked on the post-test while listening to the melody used for the musical learning material and the other half did not listen to a melody. The written learning modality led to significantly better recall than with the spoken (d = 0.97 or sung text (d = 0.78. However, comprehension after learning with the sung modality was significantly superior compared to when learning with the written learning modality (d = 0.40. Reading leads to more focus on details, which is required to answer recall questions, while listening fosters a general understanding of the text, leading to higher levels of comprehension. Listening to the melody during the post-test phase negatively affected comprehension, irrespective of the modality during the learning phase. This can be explained by the seductive detail effect, as listening to the melody during the post-test phase may distract learners from their main task.

    This study investigates the possibilities of fostering learning based on differences in recall and comprehension after learning with texts which were presented in one of three modalities: either in a spoken, written, or sung version. All three texts differ regarding their processing, especially when considering working memory. Overall, we assume the best recall performance after learning with the written text and the best comprehension performance after learning with the sung text, respectively, compared to both other text modalities. We also analyzed whether the melody of the sung material functions as a mnemonic aid for the learners in the sung text condition. If melody and text of the sung version are closely linked, presentation of the melody during the post-test phase could foster text retrieval. 108 students either learned from a sung text performed by a professional singer, a printed text, or the same text read out loud. Half of the participants worked on the post-test while listening to the melody used for the musical learning material and the other half did not listen to a melody. The written learning modality led to significantly better recall than with the spoken ( d = 0.97) or sung text ( d = 0.78). However, comprehension after learning with the sung modality was significantly superior compared to when learning with the written learning modality ( d = 0.40). Reading leads to more focus on details, which is required to answer recall questions, while listening fosters a general understanding of the text, leading to higher levels of comprehension. Listening to the melody during the post-test phase negatively affected comprehension, irrespective of the modality during the learning phase. This can be explained by the seductive detail effect, as listening to the melody during the post-test phase may distract learners from their main task. In closing, theoretical and practical implications are discussed.

    Full Text Available Authenticated key exchange protocols are of fundamental importance in securing communications and are now extensively deployed for use in various real-world network applications. In this work, we reveal major previously unpublished security vulnerabilities in the password-based authenticated three-party key exchange protocol according to Lee and Hwang (2010: (1 the Lee-Hwang protocol is susceptible to a man-in-the-middle attack and thus fails to achieve implicit key authentication; (2 the protocol cannot protect clients’ passwords against an offline dictionary attack; and (3 the indistinguishability-based security of the protocol can be easily broken even in the presence of a passive adversary. We also propose an improved password-based authenticated three-party key exchange protocol that addresses the security vulnerabilities identified in the Lee-Hwang protocol.

    The efficacy of using sung words as a mnemonic device for verbal memory has been documented in persons with probable Alzheimer's dementia (AD), but it is not yet known whether this effect is related to music training. Given that music training can enhance cognitive functioning, we explored the effects of music training and modality (sung vs. spoken) on verbal memory in persons with and without AD. We used a mixed factorial design to compare learning (5 trials), delayed recall (30-min and, 24-hour), and recognition of sung versus spoken information in 22 healthy elderly (15 musicians), and 11 people with AD (5 musicians). Musicians with AD showed better total learning (over 5 trials) of sung information than nonmusicians with AD. There were no significant differences in delayed recall and recognition accuracy (of either modality) between musicians with and without AD, suggesting that music training may facilitate memory function in AD. Analysis of individual performances showed that two of the five musicians with AD were able to recall some information on delayed recall, whereas the nonmusicians with AD recalled no information on delay. The only significant finding in regard to modality (sung vs. spoken) was that total learning was significantly worse for sung than spoken information for nonmusicians with AD. This may be due to the need to recode information presented in song into spoken recall, which may be more cognitively demanding for this group. This is the first study to demonstrate that music training modulates memory of sung and spoken information in AD. The mechanism underlying these results is unclear, but may be due to music training, higher cognitive abilities, or both. Our findings highlight the need for further research into the potentially protective effect of music training on cognitive abilities in our aging population.

  9. Beyond Authoritarian Personality: The Culture-Inclusive Theory of Chinese Authoritarian Orientation.

    Science.gov (United States)

    Chien, Chin-Lung

    2016-01-01

    In a dyad interaction, respecting and obeying those with high status (authority) is highly valued in Chinese societies. Regarding explicit behaviors, Chinese people usually show respect to and obey authority, which we call authoritarian orientation. Previous literature has indicated that Chinese people have a high degree of authoritarian personality, which was considered a national character. However, under Confucian relationalism (Hwang, 2012a), authoritarian orientation is basically an ethical issue, and thus, should not be reduced to the contention of authoritarian personality. Based on Yang's (1993) indigenous conceptualization, Chien (2013) took an emic bottom-up approach to construct an indigenous model of Chinese authoritarian orientation; it represents a "culture-inclusive theory." However, Chien's model lacks the role of agency or intentionality. To resolve this issue and to achieve the epistemological goal of indigenous psychology (that is, "one mind, many mentalities"), this paper took the "cultural system approach" (Hwang, 2015b) to construct a culture-inclusive theory of authoritarian orientation in order to represent the universal mind of human beings as well as the mentalities of people in a particular culture. Two theories that reflect the universal mind, the "Face and Favor model" (Hwang, 1987) and the "Mandala Model of Self" (Hwang, 2011a,c), were used as analytical frameworks for interpreting Chien's original model. The process of constructing the culture-inclusive theory of authoritarian orientation may represent a paradigm for the construction of indigenous culture-inclusive theories while inspiring further development. Some future research directions are proposed herein.

    Geological processes involved in the formation of Carbonatite rocks are complex and so is the understanding about its formational temperature. Fluid inclusion studies (1) on Carbonatite and their associated Ijolites showed a homogenization temperature of 1000-1100°C for Ijoltes and a temperature (T) range of 200-600°C was assigned to the carbonatite melts. Liquid immiscibility process is held responsible for the origin of parental carbonated (ijolititic/ nephelinitic) magma. The homogenization T signifies about a time interval during which there must be a considerable amount of T dropdown soon after the formation of Ijolite and subsequent crystallization of the residual carbonatite magma. However the lack of information about the T of the primary carbonated melt remains as an important area of petrological research. Experimental studies suggest a T range of 950-1400°C for the primary carbonate melt (2). Advent of Clumped isotope thermometry (3) allowed independent method for estimation of the formational T and provide avenues to derive composition of CO2 in equilibrium with carbonate melt. Earlier attempt involving carbonatites from several locations (4) captured range of T between 83°-416°C . Here we present our observation on calcite growth T in the carbonatites from the Cretaceous Sung valley ultramafic-alkaline-carbonatite complex. Based on stable C,O isotope study and Sr, Nd isotopic composition a mantle origin- genetically linked with the Kerguelen plume was proposed (5). Clumped isotope study on the same samples revealed consistent C and O isotope compositions, providing Δ47 values ranging from 0.32 to 0.48. δ13C and δ18O (in VPDB) values of the present study falls within the "Primary Igneous Carbonatite Field" (6). Using high T thermometry equation (7) we obtained a T range of 137-474 °C for the calcite present in the samples. The T recorded in our study is lower than that deduced experimental values of 960-625°C at 0.1 GPa (8) and fluid inclusion

    2017-01-01

    Music can be a powerful mnemonic device, as shown by a body of literature demonstrating that listening to text sung to a familiar melody results in better memory for the words compared to conditions where they are spoken. Furthermore, patients with a range of memory impairments appear to be able to form new declarative memories when they are encoded in the form of lyrics in a song, while unable to remember similar materials after hearing them in the spoken modality. Whether music facilitates the acquisition of completely new information, such as new vocabulary, remains unknown. Here we report three experiments in which adult participants learned novel words in the spoken or sung modality. While we found no benefit of musical presentation on free recall or recognition memory of novel words, novel words learned in the sung modality were more strongly integrated in the mental lexicon compared to words learned in the spoken modality. This advantage for the sung words was only present when the training melody was familiar. The impact of musical presentation on learning therefore appears to extend beyond episodic memory and can be reflected in the emergence and properties of new lexical representations.

Second, using the SAS process, solid dispersions of sirolimus-polyvinylpyrrolidone (PVP K30 nanoparticles were prepared with or without surfactants such as sodium lauryl sulfate (SLS, tocopheryl propylene glycol succinate, Sucroester 15, Gelucire 50/13, and Myrj 52. A mean particle size of approximately 250 nm was obtained for PVP K30-sirolimus nanoparticles. Solid state characterization, kinetic solubility, powder dissolution, stability, and pharmacokinetics were analyzed in rats.Results: X-ray diffraction, differential scanning calorimetry, and high-pressure liquid chromatography indicated that sirolimus existed in an anhydrous amorphous form within a solid dispersion of nanoparticles and that no degradation occurred after SAS processing. The improved supersaturation and dissolution of sirolimus as a solid dispersion of nanoparticles appeared to be well correlated with enhanced bioavailability of oral sirolimus in rats. With oral administration of a solid dispersion of PVP K30-SLS-sirolimus nanoparticles, the peak concentration and AUC0→12h of sirolimus were increased by approximately 18.3-fold and 15.2-fold, respectively.Conclusion: The results of this study suggest that preparation of PVP K30-sirolimus-surfactant nanoparticles using the SAS process may be a promising approach for improving the bioavailability of sirolimus

For comparison, fenofibrate-loaded Neusilin UFL2 was prepared by solvent evaporation and hot melt-adsorption methods. The fenofibrate formulations prepared were characterized by differential scanning calorimetry, powder x-ray diffractometry, specific surface area, pore size distribution, scanning electron microscopy, and energy-dispersive x-ray spectrometry. In vitro dissolution and in vivo bioavailability were also investigated.Results: Fenofibrate was distributed into the pores of Neusilin UFL2 and showed reduced crystal formation following adsorption. Supercritical CO2 facilitated the introduction of fenofibrate into the pores of Neusilin UFL2. Compared with raw fenofibrate, fenofibrate from the prepared powders showed a significantly increased dissolution rate and better bioavailability. In particular, the area under the drug concentration-time curve and maximal serum concentration of the powders prepared using supercritical CO2 were 4.62-fold and 4.52-fold greater than the corresponding values for raw fenofibrate.Conclusion: The results of this study highlight the usefulness of the melt-adsorption method using supercritical CO2 for improving the bioavailability of fenofibrate.Keywords: fenofibrate

    2012-01-01

    In a previous study (Simmons-Stern, Budson, & Ally 2010), we found that patients with Alzheimer’s disease (AD) better recognized visually presented lyrics when the lyrics were also sung rather than spoken at encoding. The present study sought to further investigate the effects of music on memory in patients with AD by making the content of the song lyrics relevant for the daily life of an older adult and by examining how musical encoding alters several different aspects of episodic memory. Patients with AD and healthy older adults studied visually presented novel song lyrics related to instrumental activities of daily living (IADL) that were accompanied by either a sung or a spoken recording. Overall, participants performed better on a memory test of general lyric content for lyrics that were studied sung as compared to spoken. However, on a memory test of specific lyric content, participants performed equally well for sung and spoken lyrics. We interpret these results in terms of a dual-process model of recognition memory such that the general content questions represent a familiarity-based representation that is preferentially sensitive to enhancement via music, while the specific content questions represent a recollection-based representation unaided by musical encoding. Additionally, in a test of basic recognition memory for the audio stimuli, patients with AD demonstrated equal discrimination for sung and spoken stimuli. We propose that the perceptual distinctiveness of musical stimuli enhanced metamemorial awareness in AD patients via a non-selective distinctiveness heuristic, thereby reducing false recognition while at the same time reducing true recognition and eliminating the mnemonic benefit of music. These results are discussed in the context of potential music-based memory enhancement interventions for the care of patients with AD. PMID:23000133

    Armillary sphere, generally known as, not only astronomical instrument for observing astronomical phenomena but also symbolizes the royal authority and royal political ideology which is based on Confucianism. Among the well-reputed Confucian scholars were built their own armillary spheres. However, these armillary spheres which exist are damaged and most of parts of its have been lost. We analyzed and measured the remnants of armillary spheres which were made by Toegye Lee Hwang, Uam Song Si-Yeol and Goedam Bae Sang-Yeol who were well-reputed Confucian scholars in Joseon Dynasty, and have been executed the restorations of Toegye Lee Hwang and Song Si-Yeols armillary sphere based on the drawings which were drawn as the original form by analysis and measurement of its remnants.

    Full Text Available ABSTRACT Background : There are approximately 15,000 workers in several spurious eyelash industries in Purbalingga Regency. Since objects being observed are very fine and the tasks need high accuracy, good lighting is therefore highly required. Poor lighting can lead to visual and mental fatigue, stiffness around the eyes, eye damage and the increasing of work accidents. Sufficient intensity and good management of lighting will result a comfort environment in accordance  to achieve a safe  work environment. Method : This research was conducted as  observational study with a cross sectional approach  for 45 samples of workers. Sampling was carried out by using of systematic random sampling. Data of light intensity and reflectance were collected by measurement of light using Lux Meter and assessment of visual fatigue by using Retention Timer. Other data were collected by interviewing workers with age limitation up to 33 years old. Chi Square Test was used to analyze the data of light intensity and reflectance, work years, age, work period, distance of light to object, distance of eyes to object, relative humidity and temperature, and the correlation with the rise of visual fatigue. Result : Light intensity in the knitting section was between 301.5 – 576.7 lux with reflectance of 43.1%-89.6%. Thirty wokers (66.7% suffered from mild visual fatigue and fifteen wokers, suffered (33.3% from moderate visual fatigue. Light intensity had  an influence and significant relationship  to the occurring of visual fatigue among workers in the industry of spurious eyelash of  PT. Sung Shim International  (p < 0,05 with  Odd ratio = 10.246 (95% CI : 1.147 - 91.498.  Probability of light intensity factor to cause visual fatigue measured by a regression logistic model  was  82.9% . It was caused by  poor lighting (light intensities were measured  below 500 lux while 17.1%  was caused by  other factors. Conclusion : Most of the spurious eyelash

    Singing requires exquisite coordination between the respiratory and phonatory systems to efficiently control glottal airflow. Asymptomatic singing students underwent pulmonary function testing (PFT), videostrobolaryngoscopic examination, and measures of glottal efficiency (maximum phonation time [MPT], glottal flow rate [GFR], and phonation quotient [PQ]) performed in both a sung and spoken tone. Pulmonary function and glottal efficiency values were within reported normative data for professional singers. However, sung tones were made with significantly higher GFR and PQ and lower PQ than spoken tones. The mean GFR was not related to the degree of glottal closure (by videostrobolaryngoscopy) or underlying pulmonary support.

We investigated the effect of SF extract on human myotube differentiation and its acting pathway. Various concentrations (0.1–10 µg/mL of SF extract were applied on human skeletal muscle cells in vitro. Myotube area and fusion index were measured to quantify myotube differentiation. The maximum effect was observed at 0.5 µg/mL of SF extract, enhancing differentiation up to 1.4-fold in fusion index and 1.6-fold in myotube area at 8 days after induction of differentiation compared to control. Phosphorylation of eukaryotic translation initiation factor 4E-binding protein 1 and 70 kDa ribosomal protein S6 kinase, which initiate translation as downstream of mammalian target of rapamycin pathway, was upregulated in early phases of differentiation after SF treatment. SF also attenuated dexamethasone-induced atrophy. In conclusion, we show that SF augments myogenic differentiation and attenuates atrophy by increasing protein synthesis through mammalian target of rapamycin/70 kDa ribosomal protein S6 kinase and eukaryotic translation initiation factor 4E-binding protein 1 signaling pathway in human myotubes. SF can be a useful natural dietary supplement in increasing skeletal muscle mass, especially in the aged

To investigate the strength of the newly developed SCF-CO2 method compared with the modified conventional Bangham method, particle size, zeta potential, and polydispersity index (PDI of both liposomal formulations were characterized and compared. In addition, entrapment efficiency (EE and drug loading (DL characteristics were analyzed by reversed-phase high-performance liquid chromatography. Significantly larger particle size and PDI were revealed from the conventional method, while EE (% and DL (% did not exhibit any significant differences. The SCF-CO2 liposomes were found to be relatively smaller, multilamellar, and spherical with a smoother surface as determined by transmission electron microscopy. SCF-CO2 liposomes showed no significant differences in their particle size and PDI after more than 3 months, whereas conventional liposomes exhibited significant changes in their particle size. The initial yield (%, EE (%, and DL (% of SCF-CO2 liposomes and conventional liposomes were 90.98 ± 2.94, 92.20 ± 1.36, 20.99 ± 0.84 and 90.72 ± 2.83, 90.24 ± 1.37, 20.47 ± 0.94, respectively, which changed after 14 weeks to 86.65 ± 0.30, 87.63 ± 0.72, 18.98 ± 0.22 and 75.04 ± 8.80, 84.59 ± 5.13, 15.94 ± 2.80, respectively.

    Deficits for pitch structure processing in congenital amusia has been mostly reported for melodic stimuli and explicit judgments. The present study investigated congenital amusia with harmonic stimuli and a priming task. Amusic and control participants performed a speeded phoneme discrimination task on sung chord sequences. The target phoneme was sung either on a functionally important chord (tonic chord, referred to as "related target") or a less important one (subdominant chord, referred to as "less-related target"). Correct response times were faster when the target phoneme was sung on tonic chords rather than on subdominant chords, and this effect was less pronounced, albeit significant, in amusic participants. These data report for the first time a deficit in congenital amusia for chord processing, but also provide evidence that, despite this deficit, amusic individuals have internalized sophisticated syntactic-like functions of chords in the Western tonal musical system. This finding suggests that thanks to this musical knowledge, amusic individuals could develop expectancies for musical events, and, presumably, follow the tension-relaxation schemas in Western tonal music, which also influence emotional responses to music.

    2013-06-01

    Full Text Available Infants prefer speech to non-vocal sounds and to non-human vocalizations, and they prefer happy-sounding speech to neutral speech. They also exhibit an interest in singing, but there is little knowledge of their relative interest in speech and singing. The present study explored infants’ attention to unfamiliar audio samples of speech and singing. In Experiment 1, infants 4-13 months of age were exposed to happy-sounding infant-directed speech versus hummed lullabies by the same woman. They listened significantly longer to the speech, which had considerably greater acoustic variability and expressiveness, than to the lullabies. In Experiment 2, infants of comparable age who heard the lyrics of a Turkish children’s song spoken versus sung in a joyful/happy manner did not exhibit differential listening. Infants in Experiment 3 heard the happily sung lyrics of the Turkish children’s song versus a version that was spoken in an adult-directed or affectively neutral manner. They listened significantly longer to the sung version. Overall, happy voice quality rather than vocal mode (speech or singing was the principal contributor to infant attention, regardless of age.

We fixed suicide attempt as the dependent variable and eleven sociodemographic, intrapersonal, and extrapersonal variables as independent variables.Results: The rate of suicide attempts of the total sample was 9.5%, and severity of depression was the strongest variable to predict suicide attempt. The rates of suicide attempts in the depression and potential depression groups were 5.4 and 2.8 times higher than that of the non-depression group. In the depression group, the most powerful factor to predict a suicide attempt was delinquency, and the rate of suicide attempts in those in the depression group with higher delinquency was two times higher than in those in the depression group with lower delinquency. Of special note, the rate of suicide attempts in the depressed females with higher delinquency was the highest. Interestingly, in the potential depression group, the most impactful factor to predict a suicide attempt was intimacy with family, and the rate of suicide attempts of those in the potential depression group with lower intimacy with family was 2.4 times higher than that of those in the potential depression group with higher intimacy with family. And, among the potential depression group, middle school students with lower intimacy with family had a 2.5-times higher rate of suicide attempts than high school students with lower intimacy with family. Finally, in the non-depression group, stress level was the most powerful factor to

    Although previous studies suggest that music may facilitate verbal learning in a healthy population, such a mnemonic effect has seldom been investigated in Alzheimer's disease (AD). Moreover, memorization of texts was generally compared when either sung or spoken. In the present study, it was examined whether the benefit observed on verbal learning was specific to music or whether an associative context binding items together led to similar benefits, regardless of the nature of the association. Twelve patients with mild AD and 15 healthy controls learned texts presented with either a musical (sung) or a nonmusical association (spoken associated to a silent movie sequence) or without association (spoken alone). Immediate and delayed (after a 5-min delay) recall was measured. Main results showed that (a) sung texts were better remembered than spoken texts, both immediately and after a retention delay, for both groups; (b) the musical benefit was robust, being observed in most AD patients; (c) the nonmusical association may also facilitate verbal learning but to a lesser extent. A musical association during the encoding stage facilitates learning and retention in AD. Furthermore, this advantage seemed quite specific to music. The results are discussed with respect to the clinical applications in AD; theoretical implications are highlighted to explain the power of music as a mnemonic technique.

    2009-01-01

    In 2004 and 2005, Woo-Suk Hwang achieved international stardom with publications in Science reporting on successful research involving the creation of stem cells from cloned human embryos. The wonder and success all began to unravel, however, when serious ethical concerns were raised about the source of the eggs for this research. When the egg scandal had completely unfolded, it turned out that many of the women who provided eggs for stem cell research had not provided valid consents and that nearly 75% of the women egg providers had received cash or in-kind payments. Among those who did not receive direct benefits, some cited patriotism as their reason for participating in embryonic stem cell research, hence the question "for love or money?"--namely, patriotism versus payment. This paper summarizes the Hwang debacle with particular attention to the egg scandal and ends with some preliminary thoughts on patriotism as a motive for research participation.

    Community mobilization among female sex workers (SWs) is recognized as an effective strategy to empower SWs and increase their uptake of health services. Activities focus on increasing social cohesion between SWs by building trust, strengthening networks, and encouraging shared efforts for mutual gain. Several studies, however, suggest that high levels of interpersonal competition between SWs can pose a barrier to collective action and support. We conducted a study to examine levels of perceived competition between SWs in Mutare, Hwange and Victoria Falls in Zimbabwe in order to inform development of a community-based intervention for HIV prevention and treatment. This paper focuses on our qualitative findings and their implications for the design of HIV programming in the Zimbabwean context. Following a respondent driven sampling (RDS) survey, we explored issues related to social cohesion amongst SWs in Mutare, Hwange and Victoria Falls through in-depth interviews conducted with 22 SWs. Interviews examined dynamics of SWs' relationships and extent of social support, and were analyzed using thematic content analysis using the constant comparative method. Findings are contextualised against descriptive data extracted from the survey, which was analysed using Stata 12, adjusting for RDS. Across all sites, women described protecting each other at night, advising each other about violent or non-paying clients, and paying fines for each other following arrest. In Mutare, women gave additional examples, including physically attacking problem clients, treatment adherence support and shared saving schemes. However, interviews also highlighted fierce competition between women and deep mistrust. This reflects the reported mix of competition and support from the survey of 836 women (Mutare n = 370, Hwange n = 237, Victoria Falls n = 229). In Mutare, 92.8 % of SWs agreed there was a lot of competition; 87.9 % reported that SWs support each other. This contrasted

  16. On the electron vortex beam wavefunction within a crystal

    International Nuclear Information System (INIS)

    Mendis, B.G.

    2015-01-01

    Electron vortex beams are distorted by scattering within a crystal, so that the wavefunction can effectively be decomposed into many vortex components. Using a Bloch wave approach equations are derived for vortex beam decomposition at any given depth and with respect to any frame of reference. In the kinematic limit (small specimen thickness) scattering largely takes place at the neighbouring atom columns with a local phase change of π/2 rad. When viewed along the beam propagation direction only one vortex component is present at the specimen entrance surface (i.e. the ‘free space’ vortex in vacuum), but at larger depths the probe is in a mixed state due to Bragg scattering. Simulations show that there is no direct correlation between vortex components and the pendellösung, i.e. at a given depth probes with relatively constant can be in a more mixed state compared to those with more rapidly varying . This suggests that minimising oscillations in the pendellösung by probe channelling is not the only criterion for generating a strong electron energy loss magnetic circular dichroism (EMCD) signal. - Highlights: • Equations are derived for vortex decomposition due to scattering within a crystal. • There is no direct correlation between vortex decomposition and pendellösung. • Results are also discussed in the context of EMCD measurements

    Voigt, H.; Bandilla, A.

    In order to continue and generalize the studies of the density matrix of a light field undergoing k-photon absorption, in this paper we put the emphasis on the off-diagonal elements. The solution obtained earlier for the diagonal elements describing the photon statistics can be found as a special case but will not be discussed again. The general solution calculated by recursion shows an asymptotic behaviour if the initial photon number is sufficiently high. Only the initial phase information survives. Illustrating the solution we start with coherent light and a generalized coherent state.Translated AbstractDie Dichtematrix eines Lichtstrahls nach k-Photonen-Absorption aus einer ModeWir führen die Betrachtungen über das Verhalten der Dichtematrix eines Lichtfeldes nach k-Photonen-Absorption aus einer Mode verallgemeinernd weiter und konzentrieren uns auf die Nichtdiagonalelemente. Die im folgenden angegebene allgemeine Lösung, die durch Rekursion gefunden wurde, enthält die schon früher erhaltene, jedoch hier nicht weiter diskutierte Lösung für die Diagonalelemente als Spezialfall. Sie zeigt ferner, daß es einen asymptotischen Zustand gibt, der eine von der Ausgangsintensität unabhängige Information über die Ausgangsphase enthält. Zur Diskussion der Lösung werden verschiedene Anfangsbedingungen betrachtet, so z. B. kohärentes Licht und kohärentes Licht, das ein Medium mit nichtlinearem Brechungsindex durchlaufen hat (Kerr-Effekt).

  4. The Process of Self-Cultivation and the Mandala Model of the Self.

    Science.gov (United States)

    Wu, Meiyao

    2017-01-01

    In his Mandala model of the self, Taiwanese scholar Kwang-Kuo Hwang sees each human being as a combination or intersection of private individual and social person, and also of knowledge and action. To further elaborate the model-with a particular emphasis on teaching/learning, the development of the ideal self and spiritual transcendence-this article will explore the psychological process of self-cultivation in the light of traditional Confucian thinking, which means keeping a balance between inner/outer and self/other. The Neo-Confucian thinker Zhongsha Mou's theories of "the awareness of unexpected developments" and his meditation/cognitive thinking opposition will also be discussed. The analyzed sources will include the traditional Confucian classics (the Four Books and Liji, or Classic of Rites ) and especially the " Lessons for Learning ( Xue-Ji )" in the Classic of Rites ( Liji ), along with the relevant textual research. Based upon a cultural-semantic analysis of these classics as well as of Hwang's central ideas, the author attempts to further conceptualize the process of cultivating the ideal self in Confucian education.

    Full Text Available This research aims to apply the Fama-French models and test the effect of alternative variable of bond yield spread, default spread (RBBB – RAAA and RAAA – RF, and the term spread (RSUN10-RSUN1, as proxy variables of the business cycle, in IDX stock data during 2005-2010. Four types of asset pricing models tested are Sharpe-Lintner CAPM, Fama-French models, Hwang et al.model, and hybrid model. The results showed that the size effect and value effect has an impact on excess stock returns. Slopes of market beta, SMB, and HML are more sensitive to stock big size and high B / M. Default spreads and term spreads in Hwang et al. model can explain the value effect, and weakly explain the size effect, meanwhile the power of explanation disappeared on Hybrid models. Based on the assessment adjusted R2 and the frequency of rejection of non-zero alpha, is found that the hybrid model is the most suitable model.

    Full Text Available Huron, Dahl, and Johnson, in their paper “Facial Expression and Vocal Pitch Height: Evidence of an Intermodal Association”, demonstrated a positive correlation between the pitch of a sung note and the vertical position of the singer’s eyebrows. Moreover, other subjects viewing photographs of the faces of the singers, with the lower part of the face and neck of the singers blocked out, could accurately judge whether a high note or low note had been sung. The authors offer a number of hypothetical explanations for their findings. I propose a speculative, ethologically-based, explanation for these correlations: namely, how both pitch of voice and eyebrow position would be correlated in this way to convey to the viewer the degree of potential threat – or lack of threat – posed by the signaler.

    Full Text Available La gzhas , or Amdo Tibetan love songs, are sung between young men and women to express their love to each other. Several terms are available for this type of love song in Amdo Tibetan. La gzhas is the most common term for such songs in written Tibetan, la meaning 'mountain pass' and gzhas 'song'. In oral Amdo Tibetan, it is la-ye , a homophone of the literary term. Ri glu literally means mountain song, and this term matches the Chinese term for love songs, shan'ge. These two terms indicate where this song is often sung, in the mountains, far away from houses, villages and tents, in places where there are few people around. Rogs 'then has a more romantic connotation, rogs meaning friend or lover, and 'then meaning to pull, or hookup. ...

Die Spurrekonstruktion im oder in unmittelbarer Nähe des Primärstrahls stellt hohe Anforderungen in Bezug auf Ratenfestigkeit, Zeitauflösung, Nachweiseffizienz und Strahlenhärte aller Detektorkomponenten. Vorstudien zur Eignung von szintillierenden Fasern und Lichtleitern in Verbindung mit Vielkanal-Photomultipliern führten zur Fertigung eines Prototyps, der bei nominalen Bedingungen intensiv getestet wurde. Mit den hieraus gewonnen Erfahrungen wurden insgesamt vier Faserhodoskope realisiert und im Rahmen des COMPASS-Experiments betrieben. Hierbei wurde eine intrinsische Detektoreffizienz von nahezu 100% erreicht.

  8. Neural substrates for semantic memory of familiar songs: is there an interface between lyrics and melodies?

    2012-01-01

    Findings on song perception and song production have increasingly suggested that common but partially distinct neural networks exist for processing lyrics and melody. However, the neural substrates of song recognition remain to be investigated. The purpose of this study was to examine the neural substrates involved in the accessing "song lexicon" as corresponding to a representational system that might provide links between the musical and phonological lexicons using positron emission tomography (PET). We exposed participants to auditory stimuli consisting of familiar and unfamiliar songs presented in three ways: sung lyrics (song), sung lyrics on a single pitch (lyrics), and the sung syllable 'la' on original pitches (melody). The auditory stimuli were designed to have equivalent familiarity to participants, and they were recorded at exactly the same tempo. Eleven right-handed nonmusicians participated in four conditions: three familiarity decision tasks using song, lyrics, and melody and a sound type decision task (control) that was designed to engage perceptual and prelexical processing but not lexical processing. The contrasts (familiarity decision tasks versus control) showed no common areas of activation between lyrics and melody. This result indicates that essentially separate neural networks exist in semantic memory for the verbal and melodic processing of familiar songs. Verbal lexical processing recruited the left fusiform gyrus and the left inferior occipital gyrus, whereas melodic lexical processing engaged the right middle temporal sulcus and the bilateral temporo-occipital cortices. Moreover, we found that song specifically activated the left posterior inferior temporal cortex, which may serve as an interface between verbal and musical representations in order to facilitate song recognition.

  9. Efficient multiparty quantum-secret-sharing schemes

    International Nuclear Information System (INIS)

    Xiao Li; Deng Fuguo; Long Guilu; Pan Jianwei

    2004-01-01

    In this work, we generalize the quantum-secret-sharing scheme of Hillery, Buzek, and Berthiaume [Phys. Rev. A 59, 1829 (1999)] into arbitrary multiparties. Explicit expressions for the shared secret bit is given. It is shown that in the Hillery-Buzek-Berthiaume quantum-secret-sharing scheme the secret information is shared in the parity of binary strings formed by the measured outcomes of the participants. In addition, we have increased the efficiency of the quantum-secret-sharing scheme by generalizing two techniques from quantum key distribution. The favored-measuring-basis quantum-secret-sharing scheme is developed from the Lo-Chau-Ardehali technique [H. K. Lo, H. F. Chau, and M. Ardehali, e-print quant-ph/0011056] where all the participants choose their measuring-basis asymmetrically, and the measuring-basis-encrypted quantum-secret-sharing scheme is developed from the Hwang-Koh-Han technique [W. Y. Hwang, I. G. Koh, and Y. D. Han, Phys. Lett. A 244, 489 (1998)] where all participants choose their measuring basis according to a control key. Both schemes are asymptotically 100% in efficiency, hence nearly all the Greenberger-Horne-Zeilinger states in a quantum-secret-sharing process are used to generate shared secret information

Currently, no effective strategies are known to prevent facial wrinkles. We assessed the beneficial effects of bee-venom serum on the clinical signs of aging skin. Our results show that bee-venom serum treatment clinically improved facial wrinkles by decreasing total wrinkle area, total wrinkle count, and average wrinkle depth. Therefore, bee-venom serum may be effective for the improvement of skin wrinkles. Keywords: bee venom, wrinkle, area, count, depth

The most prominent reason for not singing some hymns or psalms is that they are unknown – text as well as tune. It is, however, often assumed that the reason why hymns and psalms are unknown is primarily because their tunes would be too difficult to sing. The role of the text and other aspects are not taken into account sufficiently. In this article, these one-sided views regarding the tunes are challenged, and it is argued that there could be many other reasons why hymns and psalms are not used.

  7. Neural substrates for semantic memory of familiar songs: is there an interface between lyrics and melodies?

    Directory of Open Access Journals (Sweden)

    Yoko Saito

    Full Text Available Findings on song perception and song production have increasingly suggested that common but partially distinct neural networks exist for processing lyrics and melody. However, the neural substrates of song recognition remain to be investigated. The purpose of this study was to examine the neural substrates involved in the accessing "song lexicon" as corresponding to a representational system that might provide links between the musical and phonological lexicons using positron emission tomography (PET. We exposed participants to auditory stimuli consisting of familiar and unfamiliar songs presented in three ways: sung lyrics (song, sung lyrics on a single pitch (lyrics, and the sung syllable 'la' on original pitches (melody. The auditory stimuli were designed to have equivalent familiarity to participants, and they were recorded at exactly the same tempo. Eleven right-handed nonmusicians participated in four conditions: three familiarity decision tasks using song, lyrics, and melody and a sound type decision task (control that was designed to engage perceptual and prelexical processing but not lexical processing. The contrasts (familiarity decision tasks versus control showed no common areas of activation between lyrics and melody. This result indicates that essentially separate neural networks exist in semantic memory for the verbal and melodic processing of familiar songs. Verbal lexical processing recruited the left fusiform gyrus and the left inferior occipital gyrus, whereas melodic lexical processing engaged the right middle temporal sulcus and the bilateral temporo-occipital cortices. Moreover, we found that song specifically activated the left posterior inferior temporal cortex, which may serve as an interface between verbal and musical representations in order to facilitate song recognition.

    The t<0 branch of pre-big bang cosmological scenarios is subject to a gravitational wave instability. The unstable behaviour of tensor perturbations is derived in a very simple way in Hwang's covariant and gauge-invariant formalism developed for extended theories of gravity. A simple interpretation of this instability as the effect of an ''antifriction'' is given, and it is argued that a universe must eventually enter the expanding phase. (orig.)

Materials and methods: The isotopes [14C] and [59Fe] were used to label the polymer backbone (CLS and iron oxide core (FLS, respectively. In addition, unradiolabeled cold superparamagnetic iron oxide nanoparticles (SPION/ULS were synthesized to characterize particle size by dynamic light scattering, morphology by transmission electron microscopy, and in vivo magnetic resonance imaging (MRI. CLS and FLS were used separately to investigate the behavior of both the synthesized polymer and [Fe] in Sprague Dawley (SD rats, respectively. Because radioactivity of the isotopes was different by β for CLS and γ for FLS, synthesis of the samples had to be separately prepared. Results: The mean particle size of the ULS was 66.1 nm, and the biodistribution of CLS concentrations in various organs, in rank order of magnitude, was liver > kidney > small intestine > other. The biodistribution of FLS concentrations was liver > spleen > lung > other. These rank orders show that synthesized SPION mainly accumulates in the liver. The differences in the distribution were caused by the SPION metabolism. Radiolabeled

  16. Testosterone affects song modulation during simulated territorial intrusions in male black redstarts (Phoenicurus ochruros.

    Directory of Open Access Journals (Sweden)

    Beate Apfelbeck

    Full Text Available Although it has been suggested that testosterone plays an important role in resource allocation for competitive behavior, details of the interplay between testosterone, territorial aggression and signal plasticity are largely unknown. Therefore, we investigated if testosterone acts specifically on signals that communicate the motivation or ability of individuals to engage in competitive situations in a natural context. We studied the black redstart, a territorial songbird species, during two different life-cycle stages, the early breeding phase in spring and the non-breeding phase in fall. Male territory holders were implanted with the androgen receptor blocker flutamide (Flut and the aromatase inhibitor letrozole (Let to inhibit the action of testosterone and its estrogenic metabolites. Controls received a placebo treatment. Three days after implantation birds were challenged with a simulated territorial intrusion (STI. Song was recorded before, during and after the challenge. In spring, both treatment groups increased the number of elements sung in parts of their song in response to the STI. However, Flut/Let-implanted males reacted to the STI with a decreased maximum acoustic frequency of one song part, while placebo-implanted males did not. Instead, placebo-implanted males sang the atonal part of their song with a broader frequency range. Furthermore, placebo-, but not Flut/Let-implanted males, sang shorter songs with shorter pauses between parts in the STIs. During simulated intrusions in fall, when testosterone levels are naturally low in this species, males of both treatment groups sang similar to Flut/Let-implanted males during breeding. The results suggest that song sung during a territorial encounter is of higher competitive value than song sung in an undisturbed situation and may, therefore, convey information about the motivation or quality of the territory holder. We conclude that testosterone facilitates context-dependent changes

    2010-08-01

    Musical mnemonics have a long and diverse history of popular use. In addition, music processing in general is often considered spared by the neurodegenerative effects of Alzheimer's disease (AD). Research examining these two phenomena is limited, and no work to our knowledge has explored the effectiveness of musical mnemonics in AD. The present study sought to investigate the effect of music at encoding on the subsequent recognition of associated verbal information. Lyrics of unfamiliar children's songs were presented bimodally at encoding, and visual stimuli were accompanied by either a sung or a spoken recording. Patients with AD demonstrated better recognition accuracy for the sung lyrics than the spoken lyrics, while healthy older adults showed no significant difference between the two conditions. We propose two possible explanations for these findings: first, that the brain areas subserving music processing may be preferentially spared by AD, allowing a more holistic encoding that facilitates recognition, and second, that music heightens arousal in patients with AD, allowing better attention and improved memory.

Recently, it has become evident that some TiO2 particles have a considerable cytotoxic effect in normal human cells. However, the molecular basis for the cytotoxicity of TiO2 has yet to be defined.Methods and results: In this study, we demonstrated that combined treatment with TiO2 nanoparticles sized less than 100 nm and ultraviolet A irradiation induces apoptotic cell death through reactive oxygen species-dependent upregulation of Fas and conformational activation of Bax in normal human cells. Treatment with P25 TiO2 nanoparticles with a hydrodynamic size distribution centered around 70 nm (TiO2P25–70 together with ultraviolet A irradiation-induced caspase-dependent apoptotic cell death, accompanied by transcriptional upregulation of the death receptor, Fas, and conformational activation of Bax. In line with these results, knockdown of either Fas or Bax with specific siRNA significantly inhibited TiO2-induced apoptotic cell death. Moreover, inhibition of reactive oxygen species with an antioxidant, N-acetyl-L-cysteine, clearly suppressed upregulation of Fas, conformational activation of Bax, and subsequent apoptotic cell death in response to combination treatment using TiO2P25–70 and ultraviolet A irradiation.Conclusion: These results indicate that sub-100 nm sized TiO2 treatment under ultraviolet A irradiation induces apoptotic cell death through reactive oxygen species-mediated upregulation of the death receptor, Fas, and activation of the preapoptotic protein

  2. On the electron vortex beam wavefunction within a crystal.

    Mendis, B G

    2015-10-01

    Electron vortex beams are distorted by scattering within a crystal, so that the wavefunction can effectively be decomposed into many vortex components. Using a Bloch wave approach equations are derived for vortex beam decomposition at any given depth and with respect to any frame of reference. In the kinematic limit (small specimen thickness) scattering largely takes place at the neighbouring atom columns with a local phase change of π/2rad. When viewed along the beam propagation direction only one vortex component is present at the specimen entrance surface (i.e. the 'free space' vortex in vacuum), but at larger depths the probe is in a mixed state due to Bragg scattering. Simulations show that there is no direct correlation between vortex components and the 〈Lz〉 pendellösung, i.e. at a given depth probes with relatively constant 〈Lz〉 can be in a more mixed state compared to those with more rapidly varying 〈Lz〉. This suggests that minimising oscillations in the 〈Lz〉 pendellösung by probe channelling is not the only criterion for generating a strong electron energy loss magnetic circular dichroism (EMCD) signal.

    Correlation ECE (CECE) is a diagnostic technique that allows measurement of small amplitude electron temperature, Te, fluctuations through standard cross-correlation analysis methods. In Alcator C-Mod, a new CECE diagnostic has been installed[Sung RSI 2012], and interesting phenomena have been observed in various plasma conditions. We find that local Te fluctuations near the edge (ρ ~ 0:8) decrease across the linearto- saturated ohmic confinement transition, with fluctuations decreasing with increasing plasma density [Sung NF 2013], which occurs simultaneously with rotation reversals [Rice NF 2011]. Te fluctuations are also reduced across core rotation reversals with an increase of plasma density in RF heated L-mode plasmas, which implies that the same physics related to the reduction of Te fluctuations may be applied to both ohmic and RF heated L-mode plasmas. In I-mode plasmas, we observe the reduction of core Te fluctuations, which indicates changes of turbulence occur not only in the pedestal region but also in the core across the L/I transition [White NF 2014]. The present CECE diagnostic system in C-Mod and these experimental results are described in this paper

    2017-09-01

    This study aims to investigate the elemental compositions in 93 Thai rice samples using instrumental neutron activation analysis (INAA) and to identify rice according to their types and rice cultivars using statistical analysis. As, Mg, Cl, Al, Br, Mn, K, Rb and Zn in Thai jasmine rice and Sung Yod rice samples were successfully determined by INAA. The accuracy and precision of the INAA method were verified by SRM 1568a Rice Flour. All elements were found to be in a good agreement with the certified values. The precisions in term of %RSD were lower than 7%. The LODs were obtained in range of 0.01 to 29 mg kg-1. The concentration of 9 elements distributed in Thai rice samples was evaluated and used as chemical indicators to identify the type of rice samples. The result found that Mg, Cl, As, Br, Mn, K, Rb, and Zn concentrations in Thai jasmine rice samples are significantly different but there was no evidence that Al is significantly different from concentration in Sung Yod rice samples at 95% confidence interval. Our results may provide preliminary information for discrimination of rice samples and may be useful database of Thai rice.

  8. [How did the castratos sing? Historical observations].

    von Deuster, Christian

    2006-01-01

    Historical observations In Church music from the early beginnings to the 19th century, women were not allowed to sing, because of a wrongly interpreted quote of the Apostle Paul. Paul had ordered women to keep silence in ecclesia, it means: in the community and in the congregation, but he himself never mentioned a ban on singing in church. The castratos gradually replaced the men singing falsetto due to the latter's weaker singing performance from the 17th century onwards. They originated mostly from simple social backgrounds. Many poor families in Italy in the 17th and 18th centuries had up to 15 children and there was far too little work for the population. Some castratos were the stars of the opera. But as human beings they were discriminated. The castration took place mostly between the 7th and 12th years of their lives and many died as a result of the operation. The singing-lessons thereafter lasted 5-6 years. In the 18th century, the most famous castrato was Carlo Broschi, named Farinelli (1705-1782). Numerous arias sung by him are still in existence as scores, some are high quality concert pieces. There are modem versions on CD sung by a counter-tenor or a mezzo-soprano as soloists. Farinelli was able, during a visit to Spain, to improve with his singing the mood of two severely depressive kings. In the late 18th and in the 19th century, the castratos were increasingly replaced by tenors and women singers. The only historical sound recordings were sung by one of the last castratos, Alessandro Moreschi (1858-1922). The recordings were made in 1902 and 1904 in the Vatican. The arias are in the style of the end of the 19th century and contain no longer anything of the bravura arias so admired by the audiences in the 18th century. Since the end of World War II, the high male voices have experienced a renaissance.

Methods: Excipients used for enhancing the solubility and stability of sirolimus were screened. A phase-separation test, visual observation for emulsifying efficiency, and droplet size analysis were performed. Ternary phase diagrams were constructed to optimize the liquid SMEDDS formulation. The selected liquid SMEDDS formulations were prepared into solid form. The dissolution profiles and pharmacokinetic profiles in rats were analyzed. Results: In the results of the oil and cosolvent screening studies, Capryol™ Propylene glycol monocaprylate (PGMC and glycofurol exhibited the highest solubility of all oils and cosolvents, respectively. In the surfactant screening test, D-α-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS was determined to be the most effective stabilizer of sirolimus in pH 1.2 simulated gastric fluids. The optimal formulation determined by the construction of ternary phase diagrams was the T32 (Capryol™ PGMC:glycofurol:vitamin E TPGS = 30:30:40 weight ratio formulation with a mean droplet size of 108.2 ± 11.4 nm. The solid SMEDDS formulations were prepared with Sucroester 15 and mannitol. The droplet size of the reconstituted solid SMEDDS showed no significant difference compared with the liquid SMEDDS.

    In a recent paper (Hwang et al 2011 Phys. Scr. 83 045004), a subtle quantum secret sharing (QSS) protocol was proposed. One major advantage of this protocol is its high efficiency; that is, it is more efficient than other QSS protocols using the Greenberger-Horne-Zeilinger states. However, we analyzed the security of this protocol and found that it is insecure for one agent who may deduce half of the information about the deal's secret directly just by his/her piece of secret. Finally, a feasible improvement of this QSS protocol is put forward.

  1. Singing with yourself: evidence for an inverse modeling account of poor-pitch singing.

    Science.gov (United States)

    Pfordresher, Peter Q; Mantell, James T

    2014-05-01

    Singing is a ubiquitous and culturally significant activity that humans engage in from an early age. Nevertheless, some individuals - termed poor-pitch singers - are unable to match target pitches within a musical semitone while singing. In the experiments reported here, we tested whether poor-pitch singing deficits would be reduced when individuals imitate recordings of themselves as opposed to recordings of other individuals. This prediction was based on the hypothesis that poor-pitch singers have not developed an abstract "inverse model" of the auditory-vocal system and instead must rely on sensorimotor associations that they have experienced directly, which is true for sequences an individual has already produced. In three experiments, participants, both accurate and poor-pitch singers, were better able to imitate sung recordings of themselves than sung recordings of other singers. However, this self-advantage was enhanced for poor-pitch singers. These effects were not a byproduct of self-recognition (Experiment 1), vocal timbre (Experiment 2), or the absolute pitch of target recordings (i.e., the advantage remains when recordings are transposed, Experiment 3). Results support the conceptualization of poor-pitch singing as an imitative deficit resulting from a deficient inverse model of the auditory-vocal system with respect to pitch.

  2. Musical Mnemonics Enhance Verbal Memory in Typically Developing Children

    Full Text Available The purpose of this study was to compare the effects of musical mnemonics vs. spoken word in training verbal memory in children. A randomized control trial of typically-developing 9–11 year old children was conducted using the Rey Auditory Verbal Learning Test (RAVLT, a test measuring a participant's ability to recall a list of 15 words over multiple exposures. Members of the group who listened to words sung to them recalled an average of 20% more words after listening to and recalling an interference list than members of the control group who listened to the same words spoken. This difference persisted, though slightly smaller (17% when participants recalled words after a 15-min waiting period. Additionally, group participants who listened to words sung demonstrated a higher incidence of words recalled in correct serial order. Key findings were all statistically significant at the P < 0.05 level. Enhanced serial order recall points to the musical pitch/rhythm structure enhancing sequence memory as a potential mnemonic mechanism. No significant differences were found in serial position effects between groups. The findings suggest that musical mnemonic training may be more effective than rehearsal with spoken words in verbal memory learning tasks in 9–11 year olds.

    A detailed and comprehensive theoretical description of X-ray diffraction moiré fringes for a bicrystal specimen is given on the basis of a calculation by plane-wave dynamical diffraction theory, where the effect of the Pendellösung intensity oscillation on the moiré pattern is explained in detail. A detailed and comprehensive theoretical description of X-ray diffraction moiré fringes for a bicrystal specimen is given on the basis of a calculation by plane-wave dynamical diffraction theory. Firstly, prior to discussing the main subject of the paper, a previous article [Yoshimura (1997 ▸). Acta Cryst. A53, 810–812] on the two-dimensionality of diffraction moiré patterns is restated on a thorough calculation of the moiré interference phase. Then, the properties of moiré fringes derived from the above theory are explained for the case of a plane-wave diffraction image, where the significant effect of Pendellösung intensity oscillation on the moiré pattern when the crystal is strained is described in detail with theoretically simulated moiré images. Although such plane-wave moiré images are not widely observed in a nearly pure form, knowledge of their properties is essential for the understanding of diffraction moiré fringes in general

  4. Music lessons are associated with increased verbal memory in individuals with Williams syndrome.

    2014-11-16

    Williams syndrome (WS) is a genetic disorder characterized by intellectual delay and an affinity for music. It has been previously shown that familiar music can enhance verbal memory in individuals with WS who have had music training. There is also evidence that unfamiliar, or novel, music may also improve cognitive recall. This study was designed to examine if a novel melody could also enhance verbal memory in individuals with WS, and to more fully characterize music training in this population. We presented spoken or sung sentences that described an animal and its group name to 44 individuals with WS, and then tested their immediate and delayed memory using both recall and multiple choice formats. Those with formal music training (average duration of training 4½ years) scored significantly higher on both the spoken and sung recall items, as well as on the spoken multiple choice items, than those with no music training. Music therapy, music enjoyment, age, and Verbal IQ did not impact performance on the memory tasks. These findings provide further evidence that formal music lessons may impact the neurological pathways associated with verbal memory in individuals with WS, consistent with findings in typically developing individuals.

    This Project is being underway to provide safety measures of the operating coal mines encouraged by the government. In the second project year, three objective coal mines, Jang Sung, Young Wol and Tae Baek, have been investigated. Jang Sung coal mine is encountering three major difficulties such as deep seam development scheme under the drainage level, appropriate control of vast ventilation networks, and hazard control from water inrush in the pocket type areas. Young Wol coal mine has various problems derived from the development of shallow depth such as problems along with the small scaled irregular mining system, penetration of surface water through the loose zone of overburden and unappropriated ventilation system and so on. In Tae Baek coal mine, the measures to prevent water inrush in thick seams, optimization of complicated ventilation and transportation system are the major problem to be tackled. This report analyzed the status of each mines in view of safety aspects and suggested the counter measures to solve the hazardous matters but, basically, it is requested to develop new technology to tackle the encountered difficulties. Besides the technical approaches, government base measures to encourage the operating coal mine is required. (author). 22 refs., tabs., figs.

    The singing of song birds can form complex signal systems comprised of numerous subunits sung with distinct combinatorial properties that have been described as syntax-like. This complexity has inspired inquiries into similarities of bird song to human language; but the quantitative analysis and description of song sequences is a challenging task. In this study, we analysed song sequences of common nightingales (Luscinia megarhynchos) by means of a network analysis. We translated long nocturn...

    2011-10-15

    In a recent paper (Hwang et al 2011 Phys. Scr. 83 045004), a subtle quantum secret sharing (QSS) protocol was proposed. One major advantage of this protocol is its high efficiency; that is, it is more efficient than other QSS protocols using the Greenberger-Horne-Zeilinger states. However, we analyzed the security of this protocol and found that it is insecure for one agent who may deduce half of the information about the deal's secret directly just by his/her piece of secret. Finally, a feasible improvement of this QSS protocol is put forward.

    Full Text Available This fMRI study examines shared and distinct cortical areas involved in the auditory perception of song and speech at the level of their underlying constituents: words, pitch and rhythm. Univariate and multivariate analyses were performed on the brain activity patterns of six conditions, arranged in a subtractive hierarchy: sung sentences including words, pitch and rhythm; hummed speech prosody and song melody containing only pitch patterns and rhythm; as well as the pure musical or speech rhythm.Systematic contrasts between these balanced conditions following their hierarchical organization showed a great overlap between song and speech at all levels in the bilateral temporal lobe, but suggested a differential role of the inferior frontal gyrus (IFG and intraparietal sulcus (IPS in processing song and speech. The left IFG was involved in word- and pitch-related processing in speech, the right IFG in processing pitch in song.Furthermore, the IPS showed sensitivity to discrete pitch relations in song as opposed to the gliding pitch in speech. Finally, the superior temporal gyrus and premotor cortex coded for general differences between words and pitch patterns, irrespective of whether they were sung or spoken. Thus, song and speech share many features which are reflected in a fundamental similarity of brain areas involved in their perception. However, fine-grained acoustic differences on word and pitch level are reflected in the activity of IFG and IPS.

    For a study of the IMF and the star-formation history of the young open cluster IC 1805, we obtained deep wide-field VRI and Hα images of IC 1805 using the CFH12K mosaic CCD camera of the CFHT on 2002 January 6 and 7. We also observed several regions in IC 1805, for a study of the reddening and massive star content, using the SITe 2000x800 CCD (Maidanak 2k CCD) and standard UBVRI filters of the AZT-22 1.5m telescope at the Maidanak Astronomical Observatory in Uzbekistan on 2003 August 18 and 2004 december 25,30. Later, we obtained additional images of the central region of IC 1805 with the Fairchild 486 CCD (SNUCam) and UBVI and Hα filters of the AZT-22 telescope on 2007 October 7 and 2009 January 19. The Spitzer mapping observations were performed on 2006 September 20 under program ID 20052 (PI: S. Wolff). For complete photometry of stars in the CFH12K FOV in 3.6 and 4.5um, we also downloaded and reduced the GLIMPSE360 data (AOR: 38753280, 38763264, 38769408, 38799104, 38798592, 38784512, PI: B. A.

    This study examined the mediated influence of a celebrated religious hero in South Korea, Cardinal Stephen Kim, through two forms of involvement--parasocial interaction and identification--on intention toward cornea donation and volunteerism, and it investigated how the news media diffused of his death. A structural equation modeling analysis with a Web-based voluntary survey of more than 1,200 people in South Korea revealed a multistep social influence process, beginning with parasocial interaction with Cardinal Kim, leading to identification with him, which predicted intention toward cornea donation and volunteerism. Additional investigations found that news of Cardinal Kim's death diffused rapidly through media and interpersonal communication. Results of this study demonstrate that religious leaders who achieve a celebrity hero status can prompt public discussion of important issues rather quickly through extensive media coverage, enabling them to promote prosocial behavior and positively affect public health.

First, we modify the Lo-Chau protocol once more so that it finally reduces to the quantum key distribution without public announcement of bases. Then we show how we can estimate the error rate in the code bits based on that in the checked bits in the proposed protocol, which is the central point of the proof. We discuss the problem of imperfect sources and that of large deviation in the error rate distributions. We discuss when the bases sequence must be discarded

The agreement may be seen as a clear evidence toward the validity of a recent suggestion of Hwang, Speth, and Brown that the sea distributions of a hadron, at low and moderate Q 2 (at least up to a few GeV 2 ), may be attributed primarily to generalized Sullivan processes

    Based on news reports from Brazilian papers, the article examines the case of scientific fraud involving cloned embryos, committed by South Korean scientist Hwang. The media generally focus on the intellectual process of science, its discoveries, and the new possibilities it promises. In this case, however, science is shown the other way around, revealing a web that interweaves elements of a radically disparate nature, like the Korean government, researchers, tools, research funds, human eggs and funguses, scientific journals, among others. These ties are what make up science in practice, yet they only become visible in the media when there is tension between them and, in this case, when something illicit happens.

    Musical action is also physical action. This is obvious in cases such as moving the arm to direct a bow across a cello string, turning the hand to control the vibrations of a drumhead or inclining the cartilages of the larynx to raise the pitch of a sung note. In addition to producing sound, however, physical motion can also serve as a means of conceiving and conveying music: motion is linked in turn to visual imagery and other aspects of the conceptualization of music.

    Memristive systems were proposed in 1976 by Leon Chua and Sung Mo Kang as a model for 2-terminal passive nonlinear dynamical systems which exhibit memory effects. Such systems were originally shown to be relevant to the modeling of action potentials in neurons in regards to the Hodgkin-Huxley model and, more recently, to the modeling of thin film materials such as TiO2-x proposed for non-volatile resistive memory. However, over the past 50 years a variety of 3-terminal non-passive dynamical d...

  7. Insights for integrated conservation from attitudes of people toward protected areas near Hwange National Park, Zimbabwe.

    Increase in human settlements at the edge of protected areas (PAs) is perceived as a major threat to conservation of biodiversity. Although it is crucial to integrate the interests of surrounding communities into PA management, key drivers of changes in local populations and the effects of conservation on local livelihoods and perceptions remain poorly understood. We assessed population changes from 1990 to 2010 in 9 villages located between 2 PAs with different management policies (access to natural resources or not). We conducted semi-directive interviews at the household level (n =217) to document reasons for settlement in the area and villager's attitudes toward the PAs. We examined drivers of these attitudes relative to household typology, feelings about conservation, and concerns for the future with mixed linear models. Population increased by 61% from 2000 to 2010, a period of political and economic crisis in Zimbabwe. Forty-seven percent of immigrants were attracted by the area; others had been resettled from other villages or were returning to family lands. Attitudes toward PAs were generally positive, but immigrants attracted by the area and who used resources within the PA with fewer restrictions expressed more negative attitudes toward PAs. Household location, losses due to wild animals, and restrictions on access to natural resources were the main drivers of this negative attitude. Profit-seeking migrants did not expect these constraints and were particularly concerned with local overpopulation and access to natural resources. To avoid socio-ecological traps near PAs (i.e., unforeseen reduced adaptive capacity) integrated conservation should address mismatches between management policy and local expectations. This requires accounting for endogenous processes, for example, local socio-ecological dynamics and values that shape the coexistence between humans and wildlife. © 2013 Society for Conservation Biology.

    While North Korea accused South Korea of starting a “civil war” (naeran) during the Korean War, it has now moved away from such depictions to paint the war as an American war of imperialist aggression against Korea that was victoriously thwarted under the leadership of Kim Il Sung. In this regard, it may be more than a coincidence that the Victorious Fatherland Liberation War Museum in Pyongyang was built in the early 1970s, just as the Vietnam War drew to a close with a Vietnamese victory.

    Prompt γ-ray analysis using the internal monostandard method was applied to voluminous archaeological bronze mirrors produced in ancient China. Sn/Cu content ratios were determined nondestructively by this method. Furthermore, Au/Cu, As/Cu, and Sb/Cu content ratios were determined by means of measuring decay γ-rays emitted from radioactive nuclides produced within samples via (n,γ) reactions. It is clear that the Sn/Cu content ratios in bronze mirrors produced in the Sung era is smaller than in ones produced in between the Han and the Tung era. (author)

  1. Electricity from bagasse in Zimbabwe

    2003-01-01

    Zimbabwe has suffered electrical power shortages resulting in electrical energy imports rising to between 40% and 50% of total energy needs. Electricity generation capacity has stagnated at around 2000 Megawatts (MW e ) since 1985, when two thermal units totaling 440 MW e were completed at Hwange. The effective capacity is 1.75 GW e . The current plan is to increase capacity by installing 600 MW e at Hwange at a cost of at least US $ 600 million. Raising this level of capital is difficult hence over the last 15 years there has been a failure to increase capacity. This article is based on a study of bagasse cogeneration in Zimbabwe and Mauritius conducted over a two-year period. It discusses technology improvements that can be made in the sugar sector to improve process and energy efficiency for the purposes of becoming an independent power producer that supplies power to the grid continuously throughout the year. Power plant investment in the sugar industry offers a bridging and realizable alternative for electricity generation in Zimbabwe. Investment in a 35 MW e bagasse (moisturized fiber left when sugar has been extracted from sugarcane) system would require a capital of about US$ 35 million using modern technology based on experiences in Mauritius and Reunion. A technical and economic evaluation and analysis reveals that bagasse power development is technically and economically feasible if electricity is priced at the long-term marginal cost. At current import prices, financial assistance from the global environment facility and/or the clean development mechanism of the Kyoto protocol would be necessary. The solving of the current political and economic problems in the country would pave the way for attracting a technical partner and development, of bagasse power using domestic and international financing

  2. Effects of Early Bilingual Experience with a Tone and a Non-Tone Language on Speech-Music Integration.

    Directory of Open Access Journals (Sweden)

    Salomi S Asaridou

    Full Text Available We investigated music and language processing in a group of early bilinguals who spoke a tone language and a non-tone language (Cantonese and Dutch. We assessed online speech-music processing interactions, that is, interactions that occur when speech and music are processed simultaneously in songs, with a speeded classification task. In this task, participants judged sung pseudowords either musically (based on the direction of the musical interval or phonologically (based on the identity of the sung vowel. We also assessed longer-term effects of linguistic experience on musical ability, that is, the influence of extensive prior experience with language when processing music. These effects were assessed with a task in which participants had to learn to identify musical intervals and with four pitch-perception tasks. Our hypothesis was that due to their experience in two different languages using lexical versus intonational tone, the early Cantonese-Dutch bilinguals would outperform the Dutch control participants. In online processing, the Cantonese-Dutch bilinguals processed speech and music more holistically than controls. This effect seems to be driven by experience with a tone language, in which integration of segmental and pitch information is fundamental. Regarding longer-term effects of linguistic experience, we found no evidence for a bilingual advantage in either the music-interval learning task or the pitch-perception tasks. Together, these results suggest that being a Cantonese-Dutch bilingual does not have any measurable longer-term effects on pitch and music processing, but does have consequences for how speech and music are processed jointly.

Possible etiologies are deafness, psychiatric disorders such as schizophrenia, major depression, use of medication and stress, besides neurologic diseases including epilepsy, stroke and cancer. Uncommon etiologies encompass infectious diseases, metabolic disorders, and sensory deprivation. Although musical hallucinations have a major impact on patients' lives, they have been undervalued and understudied in the literature. We report a case of a 79-year-old woman with musical hallucination (hearing a sung National anthem without cognitive impairment or hearing loss. The patient had preserved insight of her complaint and responded well to neuroleptics.

  9. Mapping the entangled ontology of science teachers' lived experience

    Daugbjerg, Peer S.; de Freitas, Elizabeth; Valero, Paola

    2015-09-01

    In this paper we investigate how the bodily activity of teaching, along with the embodied aspect of lived experience, relates to science teachers' ways of dealing with bodies as living organisms which are both the subject matter as well as the site or vehicle of learning. More precisely, the following questions are pursued: (1) In what ways do primary science teachers refer to the lived and living body in teaching and learning? (2) In what ways do primary science teachers tap into past experiences in which the body figured prominently in order to teach students about living organisms? We draw on the relational ontology and intra-action of Karen Barad (J Women Cult Soc 28(3): 801, 2003) as she argues for a "relational ontology" that sees a relation as a dynamic flowing entanglement of a matter and meaning. We combine this with the materialist phenomenological studies of embodiment by SungWon Hwang and Wolff-Michael Roth (Scientific and mathematical bodies, Sense Publishers, Rotterdam, 2011), as they address how the teachers and students are present in the classroom with/in their "living and lived bodies". Our aim is to use theoretical insights from these two different but complementary approaches to map the embodiment of teachers' experiences and actions. We build our understanding of experience on the work of John Dewey (Experience and education, Simon & Schuster, New York, 1938) and also Jean Clandinin and Michael Connelly (Handbook of qualitative research, Sage Publications, California, 2000), leading us to propose three dimensions: settings, relations and continuity. This means that bodies and settings are mutually entailed in the present relation, and furthermore that the past as well as the present of these bodies and settings—their continuity—is also part of the present relation. We analyse the entanglement of lived experience and embodied teaching using these three proposed dimensions of experience. Analysing interviews and observations of three Danish

    Song composers incorporate linguistic prosody into their music when setting words to melody, a process called “textsetting.” Composers tend to align the expected stress of the lyrics with strong metrical positions in the music. The present study was designed to explore the idea that temporal alignment helps listeners to better understand song lyrics by directing listeners’ attention to instances where strong syllables occur on strong beats. Three types of textsettings were created by aligning metronome clicks with all, some or none of the strong syllables in sung sentences. Electroencephalographic recordings were taken while participants listened to the sung sentences (primes) and performed a lexical decision task on subsequent words and pseudowords (targets, presented visually). Comparison of misaligned and well-aligned sentences showed that temporal alignment between strong/weak syllables and strong/weak musical beats were associated with modulations of induced beta and evoked gamma power, which have been shown to fluctuate with rhythmic expectancies. Furthermore, targets that followed well-aligned primes elicited greater induced alpha and beta activity, and better lexical decision task performance, compared with targets that followed misaligned and varied sentences. Overall, these findings suggest that alignment of linguistic stress and musical meter in song enhances musical beat tracking and comprehension of lyrics by synchronizing neural activity with strong syllables. This approach may begin to explain the mechanisms underlying the relationship between linguistic and musical rhythm in songs, and how rhythmic attending facilitates learning and recall of song lyrics. Moreover, the observations reported here coincide with a growing number of studies reporting interactions between the linguistic and musical dimensions of song, which likely stem from shared neural resources for processing music and speech.

    Songs naturally bind lyrics and melody into a unified representation. Using a subsequent memory paradigm, we examined the neural processes associated with binding lyrics and melodies during song encoding. Participants were presented with songs in two conditions: a unified condition (melodies sung with lyrics), and a separate condition (melodies sung with the syllable "la"). In both cases, written lyrics were displayed and participants were instructed to memorize them by repeating them covertly or by generating mental images of the songs. We expected the unified condition to recruit the posterior superior temporal gyrus, known to be involved in perceptual integration of songs, as well as the left inferior frontal gyrus (IFG). Conversely, we hypothesized that the separate condition would engage a larger network including the hippocampus to bind lyrics and melodies of songs, and the basal ganglia and the cerebellum to ensure the correct sequence coupling of verbal and musical information in time. Binding lyrics and melodies in the unified condition revealed activation of the left IFG, bilateral middle temporal gyrus (MTG), and left motor cortex, suggesting a strong linguistic processing for this condition. Binding in the separate compared to the unified condition revealed greater activity in the right hippocampus as well as other areas including the left caudate, left cerebellum, and right IFG. This study provides novel evidence for the role of the right hippocampus in binding lyrics and melodies in songs.

    1996-12-31

    Stress-strain hysteresis loops have been captured during fatigue tests performed at R=10 (compression-compression) and R=0.1 (tension-tension) on Khaya epoxy wood composites. A fatigue modulus approach, proposed by Hwang and Han in 1989, has been applied to the data and a relationship established between the initial change in fatigue modulus and fatigue life. By following changes in fatigue modulus during the first 100 test cycles it is possible to predict the life of the sample allowing rapid evaluation of the fatigue performance of wood composites. Fatigue modulus values have also been calculated for hysteresis loops captured during complex load - time history tests. Similar trends in change in fatigue modulus suggest that this approach could be used in complex loading conditions to evaluate fatigue damage accumulation and predict fatigue life. (Author)

Based on solubility measurements, surface-modified pranlukast hemihydrate microparticles were manufactured using the spray-drying method with hydroxypropylmethyl cellulose, sucrose laurate, and water and without the use of an organic solvent. The hydrophilicity of the surface-modified pranlukast hemihydrate microparticle increased, leading to enhanced dissolution and oral bioavailability of pranlukast hemihydrate without a change in crystallinity. The surface-modified microparticles with an hydroxypropylmethyl cellulose/sucrose laurate ratio of 1:2 showed rapid dissolution of up to 85% within 30 minutes in dissolution medium (pH 6.8 and oral bioavailability higher than that of the commercial product, with approximately 2.5-fold and 3.9-fold increases in area under the curve (AUC0→12 h and peak plasma concentration, respectively. Therefore, the surface-modified microparticle is an effective oral drug delivery system for the poorly water-soluble therapeutic pranlukast hemihydrate.

    This study examines the recognition of emotion in contemporary commercial music (CCM) and classical styles of singing. This information may be useful in improving the training of interpretation in singing. This is an experimental comparative study. Thirteen singers (11 female, 2 male) with a minimum of 3 years' professional-level singing studies (in CCM or classical technique or both) participated. They sang at three pitches (females: a, e1, a1, males: one octave lower) expressing anger, sadness, joy, tenderness, and a neutral state. Twenty-nine listeners listened to 312 short (0.63- to 4.8-second) voice samples, 135 of which were sung using a classical singing technique and 165 of which were sung in a CCM style. The listeners were asked which emotion they heard. Activity and valence were derived from the chosen emotions. The percentage of correct recognitions out of all the answers in the listening test (N = 9048) was 30.2%. The recognition percentage for the CCM-style singing technique was higher (34.5%) than for the classical-style technique (24.5%). Valence and activation were better perceived than the emotions themselves, and activity was better recognized than valence. A higher pitch was more likely to be perceived as joy or anger, and a lower pitch as sorrow. Both valence and activation were better recognized in the female CCM samples than in the other samples. There are statistically significant differences in the recognition of emotions between classical and CCM styles of singing. Furthermore, in the singing voice, pitch affects the perception of emotions, and valence and activity are more easily recognized than emotions. Copyright © 2018 The Voice Foundation.

    Full Text Available This paper analyzes the role of mediators in the resolution of the Aceh conflict within the framework of a three-step process. Two separate mediation efforts, one conducted by the Centre for Humanitarian Dialogue from 1999 until 2003 and a second one led by Martti Ahtisaari and his Crisis Management Initiative in 2004/2005, attempted to solve the Aceh confl ict. The author shows that beside contextual factors such as ripeness of the conflict and advantageous relations between and characteristics of the conflict parties, the success of Ahtisaari’s engagement can be further explained by procedural factors. These include mediator behaviour and mediation strategies. Furthermore the mediator’s ability to use contacts with official track one actors was crucial in securing the signing as well as the implementation of the present peace agreement. ----- Der Artikel analysiert die Rolle von Mediatoren in der Lösung des Aceh Konfl ikts mittels eines drei-Phasen Modells von Konfliktlösung. Zwei voneinander unabhängige Mediationsverfahren, jenes des Centre for Humanitarian Dialogue von 1999 bis 2003, und ein weiteres geleitet durch Martti Ahtisaari und seiner Crisis Management Initiative in 2004/2005, zielten darauf ab den Konflikt zu lösen. Der Autor zeigt, dass neben kontextuellen Faktoren wie einer “ripeness” des Konflikts sowie günstigen Veränderungen auf Seite der Konfliktparteien, prozedurale Faktoren für den Erfolg Ahtisaaris entscheidend waren. Diese Faktoren beziehen sich auf das Agieren und die Strategien des Mediators. Die Fähigkeit des Mediators, Kontakte zu offiziellen “track one” Akteuren aktiv während des Mediationsprozesses zu nutzen, bildete einen Schlüsselfaktor darin einen Friedensschluss und im weiteren Verlauf eine weitgehend erfolgreiche Umsetzung des aktuellen Abkommens zwischen den ehemaligen Konfliktparteien zu erreichen.

  10. Singing numbers…in cognitive space--a dual-task study of the link between pitch, space, and numbers.

    Fischer, Martin H; Riello, Marianna; Giordano, Bruno L; Rusconi, Elena

    2013-04-01

    We assessed the automaticity of spatial-numerical and spatial-musical associations by testing their intentionality and load sensitivity in a dual-task paradigm. In separate sessions, 16 healthy adults performed magnitude and pitch comparisons on sung numbers with variable pitch. Stimuli and response alternatives were identical, but the relevant stimulus attribute (pitch or number) differed between tasks. Concomitant tasks required retention of either color or location information. Results show that spatial associations of both magnitude and pitch are load sensitive and that the spatial association for pitch is more powerful than that for magnitude. These findings argue against the automaticity of spatial mappings in either stimulus dimension. Copyright © 2013 Cognitive Science Society, Inc.

    Full Text Available Financial distress has been invoked in the asset pricing literature to explain the anomalous patterns in the cross-section of stock returns. The risk of financial distress can be measured using indexes. George and Hwang (2010 suggest that leverage can explain the distress risk puzzle and that firms with high costs choose low leverage to reduce distress intensities and earn high returns. This study investigates whether this relationship exists in the Taiwan market. When examined separately, distress intensity is found to be negatively related to stock returns, but leverage is found to not be significantly related to stock returns. The results are the same when distress intensity and leverage are examined simultaneously. After assessing the robustness by using O-scores, distress risk puzzle is found to exist in the Taiwan market, but the leverage puzzle is not

    This paper describes an integrated model developed by the Korean Atomic Energy Research Institute (KAERI) to simulate options for disposal of spent nuclear fuel (SNF) and reprocessing products in South Korea. A companion paper (Hwang and Miller, 2009) describes a systems-level model of Korean options for spent nuclear fuel (SNF) management in the 21. century. The model addresses alternative design concepts for disposal of SNF of different types (Candu, PWR), high level waste, and fission products arising from a variety of alternative fuel cycle back ends. It uses the GoldSim software to simulate the engineered system, near-field and far-field geosphere, and biosphere, resulting in long-term dose predictions for a variety of receptor groups. The model's results allow direct comparison of alternative repository design concepts, and identification of key parameter uncertainties and contributors to receptor doses. (authors)

    Recently, Liu et al (2011 Phys. Scr. 84045015) pointed out that the multiparty quantum secret sharing (MQSS) protocol based on the GHZ state (Hwang et al 2011 Phys. Scr. 83045004) is insecure. They found that an inside participant can deduce half of the sender's secret information directly just by his piece of the secret. In order to resist this attack, an improvement was put forward. However, in this paper, we find that Liu et al's improved protocol is still insecure. We give details of three attack strategies to steal the secret information. It is shown that the eavesdropper can steal half or all of the secret information. Furthermore, a simple and ingenious MQSS protocol is proposed. We perform explicit cryptanalysis to prove that our improved protocol can resist the attacks from both the outside attackers and the inside participants, even the collusion attack.

    Ruiz, Michael J.; Wilken, David

    2018-05-01

    Tuvan throat singing, also called overtone singing, provides for an exotic demonstration of the physics of harmonics as well as introducing an Asian musical aesthetic. A low fundamental is sung and the singer skillfully alters the resonances of the vocal system to enhance an overtone (harmonic above the fundamental). The result is that the listener hears two pitches simultaneously. Harmonics such as H8, H9, H10, and H12 form part of a pentatonic scale and are commonly selected for melody tones by Tuvan singers. A real-time spectrogram is provided in a video (Ruiz M J 2018 Video: Tuvan Throat Singing and Harmonics http://mjtruiz.com/ped/tuva/) so that Tuvan harmonics can be visualized as they are heard.

The terms “polyfunctionalism”, “group melodies” or “general melodies” have been used by Estonian researches to indicate the phenomenon that many lyrics were sung to only one, or a small handful, of tunes. The scarcity of melodies is supposed to be one of several related phenomena characteristic to an oral, text-centred singing culture.In this article the Estonian folk song tradition will be analysed against a quantity of melodies and their usage in the following aspects: word-and-melody relationships and context-and-melody relationships in Karksi parish (south Estonia; a singer; and native musical terms and the process of singing and (recreation.

    2009-01-01

    This paper describes an integrated model developed by the Korean Atomic Energy Research Institute (KAERI) to simulate options for managing spent nuclear fuel (SNF) in South Korea. A companion paper (Hwang and Miller, 2009) describes a performance assessment model to address the long-term safety of alternative geological disposal options for different waste streams. The model addresses alternative concepts for storage, transportation, and processing of SNF of different types (Candu, PWR), leading up to permanent disposal in geological repositories. It uses the GoldSim software to simulate the logistics of the associated activities, including the associated capital and operating costs. The model's results allow direct comparison of alternative waste management concepts, and predict the sizes and timings of different facilities required. Future versions of the model will also address the uncertainties associated with the different system components in order to provide risk-based assessments. (authors)

    Full Text Available The CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine" was developed as a teaching tool for people interested in the production of the spoken or sung human voice. Its content comprises several subjects concerning the anatomy and physiology of spoken and sung voice. A careful assessment becomes necessary in order to ensure the effectiveness of teaching and learning educational materials, whether related to education or health, within the proposal of education mediated by technology. OBJECTIVE: This study aimed to evaluate the efficacy of the Virtual Man Project's CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine", as a self-learning material, in two different populations: Speech-Language Pathology and Audiology students and Lyrical Singing students. The participants were instructed to study the CD-ROM during 1 month and answer two questionnaires: one before and another one after studying the CD-ROM. The quantitative results were compared statistically by the Student's t-test at a significance level of 5%. RESULTS: Seventeen out of the 28 students who completed the study, were Speech-Language Pathology and Audiology students, while 11 were Lyrical Singing students (dropout rate of 44%. Comparison of the answers to the questionnaires before and after studying the CD-ROM showed a statistically significant increase of the scores for the questionnaire applied after studying the CD-ROM for both Speech-Language Pathology and Audiology and Lyrical Singing students, with p<0.001 and p<0.004, respectively. There was also a statistically significant difference in all topics of this questionnaire for both groups of students. CONCLUSION: The results concerning the evaluation of the Speech-Language Pathology and Audiology and Lyrical Singing students' knowledge before and after learning from the CD-ROM allowed concluding that the participants made significant improvement in their knowledge of the proposed

PET tracers offer non-invasive quantitative imaging in biotechnology and biomedical applications, but it requires radioisotopes as radioactive imaging tracers or radiopharmaceuticals. Method: This paper reports the synthesis of 18F-nGO-PEG by covalently functionalizing PEG with nano-graphene oxide, and its excellent stability in physiological solutions. Using a green synthesis route, nGO is then functionalized with a biocompatible PEG polymer to acquire high stability in PBS and DMEM. Results and discussion: The radiochemical safety of 18F-nGO-PEG was measured by a reactive oxygen species and cell viability test. The biodistribution of 18F-nGO-PEG could be observed easily by PET, which suggested the significantly high sensitivity tumor uptake of 18F-nGO-PEG and in a tumor bearing CT-26 mouse compared to the control. 18F-nGO-PEG was applied successfully as an efficient radiotracer or drug agent in vivo using PET imaging.

    Recent findings suggest the involvement of the cerebellum in perceptual and cognitive tasks. Our study investigated whether cerebellar patients show musical priming based on implicit knowledge of tonal-harmonic music. Participants performed speeded phoneme identification on sung target chords, which were either related or less-related to prime contexts in terms of the tonal-harmonic system. As groups, both cerebellar patients and age-matched controls showed facilitated processing for related targets, as previously observed for healthy young adults. The outcome suggests that an intact cerebellum is not mandatory for accessing implicit knowledge stored in long-term memory and for its influence on perception. One patient showed facilitated processing for less-related targets (suggesting sensory priming). The findings suggest directions for future research on auditory perception in cerebellar patients to further our understanding of cerebellar functions.

    Full Text Available Forty-four participants were asked to sing moderate, high, and low pitches while their faces were photographed. In a two-alternative forced choice task, independent judges selected the high-pitch faces as more friendly than the low-pitch faces. When photographs were cropped to show only the eye region, judges still rated the high-pitch faces friendlier than the low-pitch faces. These results are consistent with prior research showing that vocal pitch height is used to signal aggression (low pitch or appeasement (high pitch. An analysis of the facial features shows a strong correlation between eyebrow position and sung pitch—consistent with the role of eyebrows in signaling aggression and appeasement. Overall, the results are consistent with an inter-modal linkage between vocal and facial expressions.

    Full Text Available This article presents the results of a study that examines the history of the song “We Shall Not Be Moved” and the singing of it in different cultural and sociopolitical contexts over the course of two centuries. The song originated in the religious practices of African slaves in the United States in the 19th century. In the 20th century it was adopted as an anthem by labor union movements and the civil rights movement in the United States. It later arrived in Spain, where it played a role in the resistance against the Franco regime before being sung in Chile to defend the socialist project of Salvador Allende. Various theoretical concepts are used in the analysis, including those of transculturation, cosmopolitanism, and transcultural capital.

    The distinctive qualities of the cuisine of Hangzhou are the result of its geographical situation, which provided good soils, reliable rainfall, a lake that has been a water source and renowned beauty spot for centuries. The rich water-sources facilitated the development of gastronomy, agriculture, trade and administration, especially after it became the capital of the Southern Sung Dynasty. Hangzhou's food sources are especially diverse, notably for fish, green vegetables, fungi, and tofu, and have been since early records. As capital, it became a leader in cuisine, and in the development of the restaurant industry. The strength of food traditions has been reinforced constantly by the cultural, medicinal, nutritional, and social values of food and cooking, by the interest of Chinese scholars in food and wine, and by the narrative that accompanies specific dishes.

    Full Text Available The film recreates Shakespeare’s masterly play set to music 280 years later by Guiuseppe Verdi after an adaptation for the musical theatre by Arrigo Boito. Otello forms the “third way” of Verdi in which the sung word reaches a summit in doing justice to the written text, anticipating what would later be refined by “verism”. The struggle between the falsified infidelity and the amorous sentiments of the Moor of Venice provide elements that are summarised in eloquent lyricism and profound musical emotion. Zeffirelli’s Otello is a lofty concatenation of talents that affords the poetic essence and drama of the story a focused significance. Melodic nobility, singing, scenery, complemented by a constant flow of ideas, nuances, effects and hues are all there.

    Full Text Available E-learning technologies have allowed authoring and playback of standardized reusable learning objects (RLO for several years. Effective mobile learning requires similar functionality at both design time and runtime. Mobile devices can play RLO using applications like SMILE, mobile access to a learning management system (LMS, or other systems which deploy content to mobile learners (Castillo & Ayala, 2008; Chu, Hwang, & Tseng, 2010; Hsu & Chen, 2010; Nakabayashi, 2009; Zualkernan, Nikkhah, & Al-Sabah, 2009. However, implementations which author content in a mobile context do not typically permit reuse across multiple contexts due to a lack of standardization. Standards based (IMS and SCORM authoring implementations exist for non-mobile platforms (Gonzalez-Barbone & Anido-Rifon, 2008; Griffiths, Beauvoir, Liber, & Barrett-Baxendale, 2009; Téllez, 2010; Yang, Chiu, Tsai, & Wu, 2004. However, this paradigm precludes capturing learning where and when it occurs. Consequently, RLO authored for e-learning lack learner generated content, especially with timely, relevant, and location aware examples.

    Soya beans (Glycine max) 'hwang keum' were gamma-irradiated at dose levels of 0, 2 5, 5, 10 and 20 kGy and the effects of the irradiated soya beans on soya milk and tofu properties were studied. An irradiation dose of 5 kGy caused an increase in yield of soya milk and tofu while having very little effect on their quality. The properties of tofu prepared with the soya beans irradiated at 2.5-5 kGy showed no significant difference from the non-irradiated control. However, at higher doses (10-20 kGy), decreases in yield, water holding capacity and sag value of tofu were observed. Compared with the non-irradiated control, hardness and fracturability in the texture of tofu were both significantly increased when the soya bean had been irradiated at 10-20 kGy, while cohesiveness and adhesiveness decreased. The changes in color values of soya milk and tofu were pronounced at 20 kGy

    Patients with idiopathic pulmonary fibrosis have a significantly increased risk for the development of lung cancer. The morbidity and mortality of this disease combination are substantial, and, unfortunately, there are currently few data to help guide clinicians in its diagnosis and treatment. In a recent issue of this journal, Hwang et al presented one of the first studies to evaluate lung cancer in patients with idiopathic pulmonary fibrosis at the molecular level. They demonstrate variants in regulators of the cell cycle, which are known to be important in malignant transformation and may also be important in the pathogenesis of idiopathic pulmonary fibrosis. Further understanding of the pathogenic overlap between lung cancer and idiopathic pulmonary fibrosis could help point the direction to specific diagnostic modalities and targeted treatment of both conditions in the future.

    2013-01-01

    We study the braided monoidal structure that the fusion product induces on the Abelian category W p -mod, the category of representations of the triplet W-algebra W p . The W p -algebras are a family of vertex operator algebras that form the simplest known examples of symmetry algebras of logarithmic conformal field theories. We formalize the methods for computing fusion products, developed by Nahm, Gaberdiel and Kausch, that are widely used in the physics literature and illustrate a systematic approach to calculating fusion products in non-semi-simple representation categories. We apply these methods to the braided monoidal structure of W p -mod, previously constructed by Huang, Lepowsky and Zhang, to prove that this braided monoidal structure is rigid. The rigidity of W p -mod allows us to prove explicit formulae for the fusion product on the set of all simple and all projective W p -modules, which were first conjectured by Fuchs, Hwang, Semikhatov and Tipunin; and Gaberdiel and Runkel.

    We are actively pursuing applications of thermoelastic (elastocaloric) cooling using shape memory alloys. Latent heat associated with martensitic transformation of shape memory alloys can be used to run cooling cycles with stress-inducing mechanical drives. The coefficient of performance of thermoelastic cooling materials can be as high as 11 with the directly measured DT of around 17 °C. Depending on the stress application mode, the number of cycles to fatigue can be as large as of the order of 105. Efforts to design and develop thermoelastic alloys with long fatigue life will be discussed. The current project at the University of Maryland is focused on development of building air-conditioners, and at Maryland Energy and Sensor Technologies, smaller scale commercial applications are being pursued. This work is carried out in collaboration with Jun Cui, Yiming Wu, Suxin Qian, Yunho Hwang, Jan Muehlbauer, and Reinhard Radermacher, and it is funded by the ARPA-E BEETIT program and the State of Maryland.

    2016-10-01

    Full Text Available High public debt is causing serious difficulties, primarily in southern countries of the European Union that suffered the most during the business-crisis. State economists have different strategies for solving these problems, depending on their politico-economical orientation. In the neo-classical sense supply-side-policy orientated economists believe that deficit countries should first of all reduce their debts by starting an economical budget management. Demand-side-policy orientated economists, on the other hand, traditionally believe the exact opposite. Attempts should not be made to solve deficit problems through savings in budget management, although this may, at first, seem to make sense. Essentially it is vital, in this situation, to start extensive development programs to solve the structural problems and to increase the economical productivity and international competition of these countries. Both perspectives are too narrow minded as they are one-sided. They widely neglect the interdependencies of real production and monetary demand, resulting from the economic-circulatory-policy coherences. The pragmatic solution for the deficit crisis would be a combination of both approaches in the sense of: One should do one thing without neglecting the other.

The effect of the amount of gelatin and the type and amount of hydrophilic additives, namely, Gelucire® 44/14, poloxamer 407, sodium lauryl sulfate, Soluplus®, Solutol™ HS15, and D-α-tocopheryl polyethylene glycol 1000 succinate, on the droplet size, dissolution, and oral absorption of dutasteride from the SMF was investigated. Upon dispersion of the gelatin microparticle-containing SMF in water after spray-drying, the mean droplet size of the aqueous dispersion was in the range of 110–137 nm. The in vitro dissolution and recrystallization results showed that gelatin could be used as a solid carrier and recrystallization inhibitor for the SMF of dutasteride. Furthermore, combination of the gelatin microparticle-containing SMF and Soluplus enhanced the dissolution properties and oral absorption of dutasteride. The results of our study suggest that the gelatin microparticle-containing SMF in combination with Soluplus could be useful to enhance the oral absorption of dutasteride.Keywords: dissolution, solubility, bioavailability, dutasteride

Of the cognitive deficits revealed in schizophrenia or posttraumatic stress disorder (PTSD patients, the current article provides a brief review of deficit in episodic memory, which is highly predictive of patients’ quality of life and global functioning. In particular, we have focused on studies that compared relational and item-specific memory performance in schizophrenia and PTSD, because measures of relational and item-specific memory are considered the most promising constructs for immediate tangible development of clinical trial paradigm. The behavioral findings of schizophrenia are based on the tasks developed by the Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia (CNTRICS initiative and the Cognitive Neuroscience Test Reliability and Clinical Applications for Schizophrenia (CNTRACS Consortium. The findings we reviewed consistently showed that schizophrenia and PTSD are closely associated with more severe impairments in relational memory compared to item-specific memory. Candidate brain regions involved in relational memory impairment in schizophrenia and PTSD are also discussed.

    2003-01-01

    Full Text Available The Greek drama can be apprehended as an extended ritual, originating in the ceremonies of the Dionysus cult. In particular, tragedy derived its origin from the sacrifice of goats and the hymns which were sung on that occasion. Tragedia means "song of the male goat" and these hymns later developed into choruses and eventually into tragedy, in the sense of a solemn and purifying drama. The presence of the god Dionysus is evident in the history and development of the Greek drama at the beginning of the fifth century B.C. and its sudden decline 150 years later. Its rise seems to correspond with the Greek polis, where questions of justice and divine law in conflict with the individual were obviously a matter of discussion and where the drama had individual and collective catharsis (purifying in mind.

    Density of photonic states ρ (ω ) , group vg, and phase vph velocity of light, and the dispersion relation between wave vector k , and frequency ω (k ) were determined in a cholesteric photonic crystal. A highly sensitive method (measurement of rotation of the plane of polarization of light) was used to determine ρ (ω ) in samples of different quality. In high-quality samples a drastic increase in ρ (ω ) near the boundaries of the stop band and oscillations related to Pendellösung beatings are observed. In low-quality samples photonic properties are strongly modified. The maximal value of ρ (ω ) is substantially smaller, and density of photonic states increases near the selective reflection band without oscillations in ρ (ω ) . Peculiarities of ρ (ω ) , vg, and ω (k ) are discussed. Comparison of the experimental results with theory was performed.

    Full Text Available When relating his journey, Friar Diego de Ocaña describes two festivities celebrated in Villa de Potosí, both dedicated to the enthronement of images of the Virgin painted by himself. The festivities included processions as well as literary pieces to honor the Virgin. Ocaña notes that among the poetic texts composed in veneration and praise of the Virgin, there were also prayer-like compositions that were sung during the processions, at the end of the Eucharistic celebration, during the Salve Regina, or during those moments when the image was placed upon the altar. In the present article particular attention is given to various texts, specifically to those which accompanied the festivities that took place with the same pomp and circumstance as those ceremonies celebrated for the feast of Corpus Christ.

    2013-01-01

    Levitin's findings that nonmusicians could produce from memory the absolute pitches of self-selected pop songs have been widely cited in the music psychology literature. These findings suggest that latent absolute pitch (AP) memory may be a more widespread trait within the population than traditional AP labelling ability. However, it has been left unclear what factors may facilitate absolute pitch retention for familiar pieces of music. The aim of the present paper was to investigate factors that may contribute to latent AP memory using Levitin's sung production paradigm for AP memory and comparing results to the outcomes of a pitch labelling task, a relative pitch memory test, measures of music-induced emotions, and various measures of participants' musical backgrounds. Our results suggest that relative pitch memory and the quality and degree of music-elicited emotions impact on latent AP memory.

    In the years 2004 and 2005, Korea became a prospective nation noteworthy in the world through the epochal development of genetic engineering in our country. Obstinate or incurable diseases were expected to be healed in a few years by a Korean geneticist. So many worldwide patients of obstinate or incurable diseases took notice of the research outcomes and organized an aid association to collect supporting funds. World renowned journals such as 'Nature' and 'Science' published Dr. Hwang's theses. A long and distant way remedy to obstinate diseases seemed to be closer at hand so early. However, a stem cell fraud case emerged throughout the world in late 2005, the pride of the Korean people was destroyed. With this as a momentum, voices of self reflection by scientific circles were raised. The purpose of this study is not in finding the truth of the stem cell research but to propose an effective management and control measures for the future in planning, implementing, monitoring and evaluating large scale national R and D projects in order to prevent a recurrence of this kind of failure

    2009-12-01

    We respond to Hwang and Kim and Yeo's critiques of the conceptual continuity framework in science education. First, we address the criticism that their analysis fails to recognize the situated perspective of learning by denying the dichotomy of the formal and informal knowledge as a starting point in the learning process. Second, we address the critique that students' descriptions fail to meet the "gold standard" of science education—alignment with an authoritative source and generalizability—by highlighting some student-expert congruence that could serve as the foundation for future learning. Third, we address the critique that a conceptual continuity framework could lead to less rigorous science education goals by arguing that the ultimate goals do not change, but rather that if the pathways that lead to the goals' achievement could recognize existing lexical continuities' science teaching may become more efficient. In sum, we argue that a conceptual continuities framework provides an asset, not deficit lexical perspective from which science teacher educators and science educators can begin to address and build complete science understandings.

    In the minimultimedia market, functional diversity, high performance, and design are given top priority. Lightweight mobile phones of unique design especially attract customer interest and are usually considered to be highly competitive items in the marketplace. Therefore, mobile phones need wider and thinner liquid crystal displays and smaller microspeakers with high acoustic performance. There are two main directions for development of slim microspeakers. One is reducing the thickness, and the other is reducing the width. In the case of reducing the width, the total magnet volume is maintained through extending the length of the magnet circuit [S. M. Hwang et al., IEEE Trans. Magn. 39, 2003 (2003)]. In contrast, reducing the thickness results in a reduction in total magnet volume unless width is increased, which causes many difficulties in the manufacturing process. In this paper, we introduce a new magnetic circuit for slim microspeakers. This new magnetic circuit, which excludes the top plate, makes it possible to manufacture slimmer microspeakers more cost-effectively without any loss of acoustic performance.

  13. A Visual Cryptography Based Watermark Technology for Individual and Group Images

    Full Text Available The ease by which digital information can be duplicated and distributed has led to the need for effective copyright protection tools. Various techniques including watermarking have been introduced in attempt to address these growing concerns. Most watermarking algorithms call for a piece of information to be hidden directly in media content, in such a way that it is imperceptible to a human observer, but detectable by a computer. This paper presents an improved cryptographic watermark method based on Hwang and Naor-Shamir [1, 2] approaches. The technique does not require that the watermark pattern to be embedded in to the original digital image. Verification information is generated and used to validate the ownership of the image or a group of images. The watermark pattern can be any bitmap image. Experimental results show that the proposed method can recover the watermark pattern from the marked image (or group of images even if major changes are reflected on the original digital image or any member of the image group such as rotation, scaling and distortion.

    High current, high brightness electron beam accelerators promise to open up dramatic new applications. Linear induction accelerators are currently viewed as the appropriate technology for these applications. A concept by Humphries and Hwang may permit radiofrequency accelerators to fulfill the same functions with greater simplicity and enhanced flexibility. This concept involves the replacement of vacuum rf cavities with dielectric filled ones. Simple analysis indicates that the resonant frequencies are reduced by a factor of ({epsilon}{sub 0}/{epsilon}){sup 1/2} while the stored energy is increased by {epsilon}/{epsilon}{sub 0}. For a high dielectric constant like water, this factor can approach 80. A series of numerical calculations of simple pill-box cavities was performed. Eigenfunctions and resonant frequencies for a full system configuration, including dielectric material, vacuum beamline, and a ceramic window separating the two have been computed. These calculations are compared with the results of a small experimental cavity which have been constructed and operated. Low power tests show excellent agreement. (author). 4 figs., 8 refs.

    The present study aimed to investigate the contact quotient (CQ) values of breathy, normal, and pressed phonation types in four different sections of the female singing range. Electroglottography (EGG) and acoustic signals were recorded from 10 female singing teachers. Five vowels were sung for 1-3 seconds each, in three phonation types-normal, breathy, and pressed, in four pitches representing registration change points in the singing range. CQ values were automatically generated from the EGG signal using VoceVista at 35% threshold level. Sound pressure levels were checked in Praat. Unianova and correlations were performed using an SPSS program. CQ values of female participants in the study yielded ranges of 0.25-0.62 in normal and 0.34-0.73 in pressed. Normal and pressed CQ differed significantly from each other at P singing. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    A report published by the U.S. National Research Council indicates that appropriate methods for assessing reliability are key to establishing the acceptability of digital instrumentation and control (I and C) systems in safety-critical plants such as NPPs. Since the release of this issue, the methodology for the probabilistic safety assessment (PSA) of digital I and C systems has been studied. However, there is still no widely accepted method. Kang and Sung found three critical factors for safety assessment of digital systems: detection coverage of fault-tolerant techniques, software reliability quantification, and network communication risk. In reality the various factors composing digitalized I and C systems are not independent of each other but rather closely connected. Thus, from a macro point of view, a method that can integrate risk factors with different characteristics needs to be considered together with the micro approaches to address the challenges facing each factor.

  20. Carbonatite magmatism in northeast India

    Science.gov (United States)

    Kumar, D.; Mamallan, R.; Dwivedy, K. K.

    The Shillong Plateau of northeast India is identified as an alkaline province in view of the development of several carbonatite complexes e.g. the Sung Valley (Jaintia Hills), Jasra (Karbi-Anglong), Samchampi and Barpung (Mikir Hills) and lamprophyre dyke swarms (Swangkre, Garo-Khasi Hills). On the basis of limited KAr data, magmatic activity appears to have taken place over a protracted period, ranging from the Late Jurassic to the Early Cretaceous. The carbonatite complexes of the Shillong Plateau share several common traits: they are emplaced along rift zones, either within Archaean gneisses or Proterozoic metasediments and granites, and exhibit enrichment in the light rare-earth elements, U, Th, Nb, Zr, Ti, K and Na. The enrichment in incompatible trace elements can best be accounted for if the parental magmas were of alkali basaltic type (e.g. mela-nephelinite or carbonate-rich alkali picrite).

  1. On the chanting space and hymns that were sung in it. Searching for chanting-architectural connections in the middle ages

    2017-01-01

    Full Text Available The search for the unexplained interactions of domestic medieval liturgical music and sacred architecture of the Moravian style has not been the subject of interdisciplinary study so far. A reflection on the potential relationg between church chanting and architecture is absent from the largest part of the existing literature on the development of medieval sacral art. The scarcity of written historical sources, and especially musical ones, made it particularly difficult to define the connection between the chanting circumstances and the changes in the architectural form of the late Byzantine period, which is almost a standardized Moravian architectural form. The earliest preserved bilingual - Greek-Slavic neumatic manuscripts, mentioning both the names of the first famous Serbian medieval composers, and the more or less well known late Byzantine musicians who had actively participated in the earliest religious services of the Serbian Church, confirm that the culmination of the chanting art in Serbia occured precisely at the turn of the 15th century and then until the fall of Serbia under Turkish rule. Comparing the available data, with a general insight into the migration flows that led to the Byzantinization of Serbian culture in that period, showed that after the reconciliation of the Serbian Patriarchate and the Patriarchate of Constantinople, in 1374, the world-class building tradition was adopted, which until then was sporadically seen on the Serbian soil. The architectural form of the Moravian style would become recognizable by the singing apses in the axis of the transept, in the middle of the already adopted form of the inscribed cross from the early 14th century. Within the framework of the overall church, political and cultural transformation that was visible in Serbian society, the chanting practice of the Serbian Church, or more precisely the greater affirmation of the liturgical art and the increase in the number of the chanters, certainly had a share both in acceptance and in the consistent implementation of the architectural solutions of the Moravian style. Future research should focus on the holistic analysis of the Moravian cultural heritage, in order to map the movement of the known and unknown Serbian Greek melods and determine the scope of their activity. The existing knowledge of the architectural features of the Moravian sacred buildings will thus receive a significant addition, from the liturgical and religious service in which each form of church art is individually represented as part of a much more complex artistic ensemble with which the Kingdom of Heaven on the Earth is iconized.

    To get insights into the temporal pattern of commensal Escherichia coli populations, we sampled the feces of four healthy cows from the same herd in the Hwange District of Zimbabwe daily over 25 days. The cows had not received antibiotic treatment during the previous 3 months. We performed viable E. coli counts and characterized the 326 isolates originating from the 98 stool samples at a clonal level, screened them for stx and eae genes, and tested them for their antibiotic susceptibilities. We observed that E. coli counts and dominant clones were different among cows, and very few clones were shared. No clone was shared by three or four cows. Clone richness and evenness were not different between cows. Within each host, the variability in the E. coli count was evidenced between days, and no clone was found to be dominant during the entire sampling period, suggesting the existence of clonal interference. Dominant clones tended to persist longer than subdominant ones and were mainly from phylogenetic groups A and B1. Five E. coli clones were found to contain both the stx 1 and stx 2 genes, representing 6.3% of the studied isolates. All cows harbored at least one Shiga toxin-producing E. coli (STEC) strain. Resistance to tetracycline, penicillins, trimethoprim, and sulfonamides was rare and observed in three clones that were shed at low levels in two cows. This study highlights the fact that the commensal E. coli population, including the STEC population, is host specific, is highly dynamic over a short time frame, and rarely carries antibiotic resistance determinants in the absence of antibiotic treatment. IMPORTANCE The literature about the dynamics of commensal Escherichia coli populations is very scarce. Over 25 days, we followed the total E. coli counts daily and characterized the sampled clones in the feces of four cows from the same herd living in the Hwange District of Zimbabwe. This study deals with the day-to-day dynamics of both quantitative and

    2011-08-01

    This paper compared the specificity of recollections of autobiographical memories where musical cues for events were varied. We used music which was popular in the past as cues which were related to a larger number of past individual events (frequent events cues) and music which was typically only sung at graduation ceremonies as cues which were related to a smaller number of events (rare events cues). In the instructed retrieval condition, participants were told to listen to the music and to recall past events, whereas in incidental retrieval condition, the instruction was only to listen to the music. Then participants were asked to describe what they recalled while hearing the music. When frequent events musical cues were played, the specificities of the recalled events were higher in the instructed retrieval condition than in the incidental retrieval condition. In contrast, when rare events musical cues were played, there were no differences in the specificities of the recalled events.

    Full Text Available Mário de Andrade identifies rhythm as the common structural underpinning between poetry and song. Rhythm is also the apple of discord between them, since it is with rhythm that we are able to note the fundamental distinction between the sung and the spoken word. As well as differentiating language by means of its use, popular song also fluctuates rhythmically; that is, it has another ‘wave’ (or mood which varies depending on a series of other factors, which Andrade calls to mind. By considering 'canto' (chant in psycho-physical terms, this essay offers an interpretation of Andrade’s reading of the masses present at one political event in 1930 described in “Dinamogenias políticas.” Moreover, this paper connects the political with the religious practices introduced in Brazil by the Jesuits, focusing above all on the Gregorian chant. I propose that with his “Crítica do gregoriano” Andrade offers a counterpoint by which to understand popular music in Brazil.

    The dramatic turnaround of Husky Oil of Calgary, Alberta, under the leadership of John Chin-Sung Lau, a Hong Kong accountant, and one of the oil industry's toughest, most effective and most feared leaders, was described. Husky was purchased by Hong Kong interests in 1991 at which time the company was in debt to the tune of $1.2 billion. Its debt to cash ratio was 14:1. Spending on ill-conceived projects was out of control. Under Lau's uncompromising, top-down, authoritarian, inflexible management style, accompanied by some high level executive departures, massive layoffs, writing-off of $800 million in worthless assets and undeveloped properties, by 1995 the company's senior debt has been reduced to $700 million, and a modest profit of $35 million was reported. Capital investments by the company are again on the way up, and free cash flow has grown steadily in recent years to $310 million in 1995 from $85 million in 1991

The aim of this study was present a teaching methodology of Immunology and verify its efficacy as the knowledge acquisition by the participants of an event. To assess the progress of knowledge by the participants as well the use of the play and sung music, each participant fill a questionnaire, containing ten questions, before and after the presentation. The results were evaluated by paired T test at 5%. In both types there was knowledge incorporation after the play activity because the notes after the event were statistically higher. The participants remained attentive and praised the event. The knowledge showed by most of participants was considered lower and regular before the event and after the ludic activities they showed higher grades which categorized knowledge as regular and high. It was concluded that the methodology used contributed with knowledge acquisition and could contribute with the cultural and social education of the participants.

    Full Text Available Im vorliegenden Beitrag wird eine universelle Decoderarchitektur für einen Low-Density Parity-Check (LDPC Code Decoder vorgestellt. Anders als bei den in der Literatur häufig beschriebenen Architekturen für strukturierte Codes ist die hier vorgestellte Architektur frei programmierbar, so dass jeder beliebige LDPC Code durch eine Änderung der Initialisierung des Speichers für die Prüfmatrix mit derselben Hardware decodiert werden kann. Die größte Herausforderung beim Entwurf von teilparallelen LDPC Decoder Architekturen liegt im konfliktfreien Datenaustausch zwischen mehreren parallelen Speichern und Berechnungseinheiten, wozu ein Mapping und Scheduling Algorithmus benötigt wird. Der hier vorgestellte Algorithmus stützt sich auf Graphentheorie und findet für jeden beliebigen LDPC Code eine für die Architektur optimale Lösung. Damit sind keine Wartezyklen notwendig und die Parallelität der Architektur wird zu jedem Zeitpunkt voll ausgenutzt.

    Directory of Open Access Journals (Sweden)

    Michael Daley

    2007-03-01

    Full Text Available This article proposes a linguistic analysis of a recorded performance of a single verse of one of Dylan’s most popular songs—the originally released studio recording of “Like A Rolling Stone”—and describes more specifically the ways in which intonation relates to lyrics and performance. This analysis is used as source material for a close reading of the semantic, affective, and “playful” meanings of the performance, and is compared with some published accounts of the song’s reception. The author has drawn on the linguistic methodology formulated by Michael Halliday, who has found speech intonation (which includes pitch movement, timbre, syllabic rhythm, and loudness to be an integral part of English grammar and crucial to the transmission of certain kinds of meaning. Speech intonation is a deeply-rooted and powerfully meaningful aspect of human communication. This article argues that is plausible that a system so powerful in speech might have some bearing on the communication of meaning in sung performance.

    Nonmusicians remember vocal melodies (i.e., sung to la la) better than instrumental melodies. If greater exposure to the voice contributes to those effects, then long-term experience with instrumental timbres should elicit instrument-specific advantages. Here we evaluate this hypothesis by comparing pianists with other musicians and nonmusicians. We also evaluate the possibility that absolute pitch (AP), which involves exceptional memory for isolated pitches, influences melodic memory. Participants heard 24 melodies played in four timbres (voice, piano, banjo, marimba) and were subsequently required to distinguish the melodies heard previously from 24 novel melodies presented in the same timbres. Musicians performed better than nonmusicians, but both groups showed a comparable memory advantage for vocal melodies. Moreover, pianists performed no better on melodies played on piano than on other instruments, and AP musicians performed no differently than non-AP musicians. The findings confirm the robust nature of the voice advantage and rule out explanations based on familiarity, practice, and motor representations.

The poetry was written for a highly selected audience, centred around the library’ and court of the Ptolemy, and this determined the nature of both the poetry and its 'publication' or communication to the target audience. The most significant aspects of the poetry are: its heightened literary style; the transition from a sung to a recited text; the shifting of the place of communication from aristocratic banquet and public area during the previous period of the city-state to the exclusive audience of the ruler’s palace or the literary coterie; the use of erudite reference in the poem; increased experimentation by the poets in form, theme and style; and the strong sense and pursuit of individualism.

    Full Text Available This research attempts to reveal representation of Kim Jong-Un’s succession in BBC News through textual and discursive practice analysis. The data of this thesis are taken from BBC News website on 29 and 31 December 2011. The theory applied to seek the objective of the research is Critical Discourse Analysis developed by Fairclough. Through textual and discursive practice analysis, the writer finds pthat BBC employs more passive material clauses than active material clauses in depicting Kim Jong-Un’s succession. BBC also represents Kim Jong-Un’s succession as premature process where Kim Jong-Un is portrayed as a young and inexperienced leader. Besides the prematurity of the succession, the present writer finds that BBC represents Kim Jong-Un’s succession as continuity of Kim’s family dynasty. Thus, the succession is based on his resemblance to Kim Il-Sung, the founder of Democratic People’s Republic of Korea, rather than Kim Jong-Un ability and competency.

    In the years 2004 and 2005, Korea became a prospective nation noteworthy in the world through the epochal development of genetic engineering in our country. Obstinate or incurable diseases were expected to be healed in a few years by a Korean geneticist. So many worldwide patients of obstinate or incurable diseases took notice of the research outcomes and organized an aid association to collect supporting funds. World renowned journals such as 'Nature' and 'Science' published Dr. Hwang's theses. A long and distant way remedy to obstinate diseases seemed to be closer at hand so early. However, a stem cell fraud case emerged throughout the world in late 2005, the pride of the Korean people was destroyed. With this as a momentum, voices of self reflection by scientific circles were raised. The purpose of this study is not in finding the truth of the stem cell research but to propose an effective management and control measures for the future in planning, implementing, monitoring and evaluating large scale national R and D projects in order to prevent a recurrence of this kind of failure.

    Direct Doppler broadening of nuclear cross sections in Monte Carlo codes has been widely sought for coupled reactor simulations. One recent approach proposed analytical broadening using a pole representation of the commonly used resonance models and the introduction of a local windowing scheme to improve performance (Hwang, 1987; Forget et al., 2014; Josey et al., 2015, 2016). This pole representation has been achieved in the past by converting resonance parameters in the evaluation nuclear data library into poles and residues. However, cross sections of some isotopes are only provided as point-wise data in ENDF/B-VII.1 library. To convert these isotopes to pole representation, a recent approach has been proposed using the relaxed vector fitting (RVF) algorithm (Gustavsen and Semlyen, 1999; Gustavsen, 2006; Liu et al., 2018). This approach however needs to specify ahead of time the number of poles. This article addresses this issue by adding a poles and residues filtering step to the RVF procedure. This regularized VF (ReV-Fit) algorithm is shown to efficiently converge the poles close to the physical ones, eliminating most of the superfluous poles, and thus enabling the conversion of point-wise nuclear cross sections.

    The incidence of preadolescent acne among women is increasing. Acne deteriorates the quality of life; conventional treatment options are limited and have not been effective against acne, particularly acne associated with menstruation. Despite evidence that acne associated with menstruation abnormalities naturally improves when menstruation recovers to normal, there have only been few studies on the effects of dysmenorrhea treatment on acne. Therefore- we designed this study to assess the effects of gyejibokryung-hwan (GBH) and dangguijagyag-san (DJS), which are widely used in dysmenorrhea treatment, on acne associated with menstruation cycle. This is a protocol for a randomized, double-blind, parallel-group, placebo-controlled and multicenter trial. One hundred and sixteen participants with dysmenorrhea accompanied by acne vulgaris will be recruited at three centers and randomized into two groups, the herbal treatment group and placebo group. The participants will receive GBH or DJS based on pattern identification or placebo granules thrice daily for 8 weeks, with an 8-week follow up. The primary outcome will be the mean percentage change in the count of inflammatory acne lesions. The secondary outcomes would be based on dysmenorrhea numeric rating scale, verbal multidimensional scoring system for dysmenorrhea, acne numeric rating scale, investigator's static global assessment scale of facial acne vulgaris, and safety testing. Adverse events will also be reported. The effects of GBH or DJS used in dysmenorrhea treatment on acne associated with the menstrual cycle will be evaluated. The findings of this trial will provide evidence regarding the effect of herbal medicine in improving acne vulgaris associated with menstruation in women.

    Full Text Available While North Korea accused South Korea of starting a “civil war” (naeran during the Korean War, it has now moved away from such depictions to paint the war as an American war of imperialist aggression against Korea that was victoriously thwarted under the leadership of Kim Il Sung. In this regard, it may be more than a coincidence that the Victorious Fatherland Liberation War Museum in Pyongyang was built in the early 1970s, just as the Vietnam War drew to a close with a Vietnamese victory. This article examines the memorialization of the Korean War in North Korea at two pivotal historical points—the end of the Vietnam War in the 1970s and the end of the Cold War in the 1990s—with a particular focus on contemporary exhibitions at the war museum in Pyongyang. Rather than offering a simple comparison of divergent narratives about the war, the article seeks to illustrate that North Korea’s conception of history and its account of the war are staunchly modernist, with tragic consequences.

    Der Satz des Pythagoras: a²+b²=c² steht im Zentrum des Rätsels, um das es hier geht. Diese »Urformel« gilt immer und überall, aber nur in der Zweier-Potenz, mit keiner anderen ganzen Zahl. In den Notizen des französischen Mathematikers Pierre Fermat, der im 17. Jahrhundert lebte, gibt es einen Hinweis, dass er den Beweis für dieses Phänomen gefunden hat. Doch der Beweis selbst ist verschollen. 350 Jahre lang versuchten nun die Mathematiker der nachfolgenden Generationen, diesen Beweis zu führen. Keinem wollte es gelingen, manche trieb das Problem sogar in den Selbstmord. Schließlich wurde ein Preis für die Lösung des Rätsels ausgesetzt. Nun gelang dem britischen Mathematiker Andrew Wiles 1995 der Durchbruch. Simon Singh wiederum gelang es, diese auf den ersten Blick abgelegene Geschichte so zu erzählen, dass niemand und auch kein Mathematikhasser sich ihrer Faszination entziehen kann: Ein Glanzlicht des modernen Wissenschaftsjournalismus! »Dieses Buch ist ein Wunder.

    Full Text Available Die Bedeutung und der Einfluss des Werkes von Franz Rosenzweig, jüdisch-deutscher Philosoph vom Beginn des vergangenen Jahrhunderts, werden noch immer nicht angemessen gewürdigt. Rosenzweig entwickelt in seinem Hauptwerk, der Stern der Erlösung, ausgehend von eminent theologischen Kategorien, sein philosophisches System. Dem "Monolog des Ich" der traditionellen Philosophie setzt Rosenzweig ein "Neues Denken" von existenzialistischem Gepräge entgegen, das die Mündlichkeit und den Dialog mit dem "Anderen" aufwertet und den Verstand ald Werkzeug der Reflexion ersetzt. Dieses Denken weist Korrespondenzen zur Philosophie W. Benjamins auf. Das "Neue Denken" übte einen starken Einfluss auf E. Lévinas aus, sowie auf zahlreiche interessante philosophie und theologische Ansätze nach dem "linguistic turn" und auf die postmoderne jüdische Geistigkeit. Rosenzweigs Philosophie hat andererseits in seiner Übersetzertätigkeit eine wichtige direkte Anwendung gefunden. Übersetzen erscheint Rosenzweig als Verpflichtung, die aus einer Ethik, verstanden als grundlegender Philosophie, erwächst. Der vorliegende Artikel analysiert einige Aspekte der Schriften Rosenzweigs, in denen sich eine "Philosophie der Übersetzung" abzeichnet.

    We established a new disease autosomal dominant hereditary motor and sensory neuropathy with proximal dominant involvement (HMSNP) in 1997, in Okinawa, Japan. This disease is characterized by proximal dominant neurogenic atrophy with fasciculations, painful muscle cramp, obvious sensory nerve involvement, areflexia, high incidence of elevated creatine kinase levels, hyperlipidemia and hyperglycemia. (MIM %604484). HMSNP is so called or HMSNO (HMSN OKINAWA type),. These clinical features resembled those of Kennedy-Alter-Sung syndrome. Most HMSNP patients have severe muscle atrophy and finally the tracheostomy and artificial ventilation are required. Therefore, we initially thought to classify HMSNP into a subtype of motor neuron disease (MND) like familial amyotrophic lateral sclerosis (FALS) or spinal muscular atrophy (SMA). However, the general consensus for MND was no sensory involvement. Therefore, as the disease showed severe sensory involvement, we categorized HMSNP in subtype of HMSN at that time. We also reported the pathology of HMSNP, showing severely decreased anterior horn cells, decreased posterior horn cells, and loss of posterior funiculus in the spinal cord.

    2016-06-01

    Full Text Available This article analyses a 2003 documentary titled “Whose Is This Song?” by Bulgarian movie director Adela Peeva, in the purpose of understanding the relationship between the folklore and the nationalism in the Balkans. The theme of the documentary is the director’s quest to trace the roots of a folk song that she had thought was 100 percent Bulgarian since her childhood. The documentary follows Peeva’s journey with a camera in hand around Turkey, Greece, Macedonia, Albania, Bosnia and Herzegovina, Serbia and Bulgaria, where she discovers that the song is sung by all of these nations. The documentary can be interpreted as showing how an ordinary song could become an instrument of fanatical nationalism and that it reveals mutual strife instead of Balkan unity. In a region defined by ethnic hatred and war, what begins as a simply investigation of the true origins of a song, ends as a sociological and historical exploration of the deep misunderstandings between the people of the Balkans.

  8. A criterion based on computational singular perturbation for the identification of quasi steady state species: A reduced mechanism for methane oxidation with NO chemistry

    A criterion based on computational singular perturbation (CSP) is proposed to effectively distinguish the quasi steady state (QSS) species from the fast species induced by reactions in partial equilibrium. Together with the method of directed relation graph (DRG), it was applied to the reduction of GRI-Mech 3.0 for methane oxidation, leading to the development of a 19-species reduced mechanism with 15 lumped steps, with the concentrations of the QSS species solved analytically for maximum computational efficiency. Compared to the 12-step and 16-species augmented reduced mechanism (ARM) previously developed by Sung, Law and Chen, three species, namely O, CH{sub 3}OH, and CH{sub 2}CO, are now excluded from the QSS species list. The reduced mechanism was validated with a variety of phenomena including perfectly stirred reactors, auto-ignition, and premixed and non-premixed flames, with the worst-case error being less than 10% over a wide range of parameters. This mechanism was then supplemented with the reactions involving NO formation, followed by validations in both homogeneous and diffusive systems. (author)

  9. Music increases frontal EEG coherence during verbal learning.

    2007-02-02

    Anecdotal and some empirical evidence suggests that music can enhance learning and memory. However, the mechanisms by which music modulates the neural activity associated with learning and memory remain largely unexplored. We evaluated coherent frontal oscillations in the electroencephalogram (EEG) while subjects were engaged in a modified version of Rey's Auditory Verbal Learning Test (AVLT). Subjects heard either a spoken version of the AVLT or the conventional AVLT word list sung. Learning-related changes in coherence (LRCC) were measured by comparing the EEG during word encoding on correctly recalled trials to the immediately preceding trial on which the same word was not recalled. There were no significant changes in coherence associated with conventional verbal learning. However, musical verbal learning was associated with increased coherence within and between left and right frontal areas in theta, alpha, and gamma frequency bands. It is unlikely that the different patterns of LRCC reflect general performance differences; the groups exhibited similar learning performance. The results suggest that verbal learning with a musical template strengthens coherent oscillations in frontal cortical networks involved in verbal encoding.

    Full Text Available This paper offers a commentary and a new critical edition of Gausbert de Poicibot’s poem “Be·s cuget venjar Amors”, which apparently belongs to the genre of the ‘mala chanso’, that was particularly popular during the period that the Limousin poet was active. To abandon love enables the poet to recuperate reason and ‘sen’ and to justify, almost in didactic terms, his separation from the lady, thus clearly showing that he had so far sung the praises of a lady who was not worthy of receiving them. The song is also compared to other typical examples of the subgenre to which it belongs, such as “Si be·m partetz, mala dompna, de vos” by Gui d’Uissel (BdT 194.19, considered to be paradigmatic of the ‘mala chanso’ and probably familiar to Gausbert de Poicibot, though it will be pointed out that this poetic mode has roots in the work of troubadours of previous generations, such as Bernart de Ventadorn and Raimbaut d’Aurenga, whom Gausbert seems to use as models.

    2010-06-01

    Full Text Available Despite appearing in several editions and interpretations, this piece continues to pose problems. To what poetic genre does it belong? Should it be regarded as ‘fictive’ in some sense? How coherent is it, and to what should be attributed any incoherence? Are the interlocutors married or not? How many ‘dramatis personae’ are involved and who are they? It is argued here that any apparent incoherence derives from the manuscript transmission and the difficulties posed by the unusual vocabulary and popularising register, the narrative situation is simpler than has been previously thought, and wordplay or semantic ambivalence works primarily as humour rather than jongleuresque display. The piece would appear to be designed for performance as a comic sketch, imaginable in dramatised form with appropriate costumes, props and gestures, with the troubadour possibly coming on stage in his own persona as a ‘knight’, being interrupted by a ‘woman’ whose part could have been sung and acted by another man, a woman, or even the troubadour himself. The text may be aptly described as a 'fabliau' in dialogue form.

  14. Song convergence in multiple urban populations of silvereyes (Zosterops lateralis).

    2012-08-01

    Recent studies have revealed differences between urban and rural vocalizations of numerous bird species. These differences include frequency shifts, amplitude shifts, altered song speed, and selective meme use. If particular memes sung by urban populations are adapted to the urban soundscape, "urban-typical" calls, memes, or repertoires should be consistently used in multiple urban populations of the same species, regardless of geographic location. We tested whether songs or contact calls of silvereyes (Zosterops lateralis) might be subject to such convergent cultural evolution by comparing syllable repertoires of geographically dispersed urban and rural population pairs throughout southeastern Australia. Despite frequency and tempo differences between urban and rural calls, call repertoires were similar between habitat types. However, certain song syllables were used more frequently by birds from urban than rural populations. Partial redundancy analysis revealed that both geographic location and habitat characteristics were important predictors of syllable repertoire composition. These findings suggest convergent cultural evolution: urban populations modify both song and call syllables from their local repertoire in response to noise.

    2013-01-01

    Bird songs range in form from the simple notes of a Chipping Sparrow to the rich performance of the nightingale. Non-adjacent correlations can be found in the syntax of some birdsongs, indicating that the choice of what to sing next is determined not only by the current syllable, but also by previous syllables sung. Here we examine the song of the domesticated canary, a complex singer whose song consists of syllables, grouped into phrases that are arranged in flexible sequences. Phrases are defined by a fundamental time-scale that is independent of the underlying syllable duration. We show that the ordering of phrases is governed by long-range rules: the choice of what phrase to sing next in a given context depends on the history of the song, and for some syllables, highly specific rules produce correlations in song over timescales of up to ten seconds. The neural basis of these long-range correlations may provide insight into how complex behaviors are assembled from more elementary, stereotyped modules.

Nevertheless, limited safety information is available for many NPs, especially in terms of their interactions with various binding proteins, leading to potential toxic effects. Zinc oxide (ZnO NPs are included in the formulation of new products, such as adhesives, batteries, ceramics, cosmetics, cement, glass, ointments, paints, pigments, and supplementary foods, resulting in increased human exposures to ZnO. Hence, we investigated the potential ZnO nanotoxic pathways by analyzing the adsorbed proteins, called protein corona, from blood and brain from four ZnO NPs, ZnOSM20(-, ZnOSM20(+, ZnOAE100(-, and ZnOAE100(+, in order to understand their potential mechanisms in vivo. Through this study, liquid chromatography–mass spectroscopy/mass spectroscopy technology was employed to identify all bound proteins. Totals of 52 and 58 plasma proteins were identified as being bound to ZnOSM20(- and ZnOSM20(+, respectively. For ZnOAE100(- and ZnOAE100(+, 58 and 44 proteins were bound, respectively. Similar numbers of proteins were adsorbed onto ZnO irrespective of size or surface charge of the nanoparticle. These proteins were further analyzed with ClueGO, a Cytoscape plugin, which provided gene ontology and the biological interaction processes of identified proteins. Interactions between diverse proteins and ZnO nanoparticles could result in an alteration of their functions, conformation, and clearance, eventually affecting many biological processes.

  19. Adaptive memory: the survival scenario enhances item-specific processing relative to a moving scenario.

    2013-01-01

    Nairne, Thompson, and Pandeirada (2007) found that retention of words rated for their relevance to survival is superior to that of words encoded under numerous other deep processing conditions. They suggested that our memory systems might have evolved to confer an advantage for survival-relevant information. Burns, Burns, and Hwang (2011) suggested a two-process explanation of the proximate mechanisms responsible for the survival advantage. Whereas most control tasks encourage only one type of processing, the survival task encourages both item-specific and relational processing. They found that when control tasks encouraged both types of processing, the survival processing advantage was eliminated. However, none of their control conditions included non-survival scenarios (e.g., moving, vacation, etc.), so it is not clear how this two-process explanation would explain the survival advantage when scenarios are used as control conditions. The present experiments replicated the finding that the survival scenario improves recall relative to a moving scenario in both a between-lists and within-list design and also provided evidence that this difference was accompanied by an item-specific processing difference, not a difference in relational processing. The implications of these results for several existing accounts of the survival processing effect are discussed.

  20. Influence of prey dispersion on territory and group size of African lions: a test of the resource dispersion hypothesis.

    2012-11-01

    Empirical tests of the resource dispersion hypothesis (RDH), a theory to explain group living based on resource heterogeneity, have been complicated by the fact that resource patch dispersion and richness have proved difficult to define and measure in natural systems. Here, we studied the ecology of African lions Panthera leo in Hwange National Park, Zimbabwe, where waterholes are prey hotspots, and where dispersion of water sources and abundance of prey at these water sources are quantifiable. We combined a 10-year data set from GPS-collared lions for which information of group composition was available concurrently with data for herbivore abundance at waterholes. The distance between two neighboring waterholes was a strong determinant of lion home range size, which provides strong support for the RDH prediction that territory size increases as resource patches are more dispersed in the landscape. The mean number of herbivore herds using a waterhole, a good proxy of patch richness, determined the maximum lion group biomass an area can support. This finding suggests that patch richness sets a maximum ceiling on lion group size. This study demonstrates that landscape ecology is a major driver of ranging behavior and suggests that aspects of resource dispersion limit group sizes.

    Predators may influence their prey populations not only through direct lethal effects, but also through indirect behavioral changes. Here, we combined spatiotemporal fine-scale data from GPS radio collars on lions with habitat use information on 11 African herbivores in Hwange National Park (Zimbabwe) to test whether the risk of predation by lions influenced the distribution of herbivores in the landscape. Effects of long-term risk of predation (likelihood of lion presence calculated over four months) and short-term risk of predation (actual presence of lions in the vicinity in the preceding 24 hours) were contrasted. The long-term risk of predation by lions appeared to influence the distributions of all browsers across the landscape, but not of grazers. This result strongly suggests that browsers and grazers, which face different ecological constraints, are influenced at different spatial and temporal scales in the variation of the risk of predation by lions. The results also show that all herbivores tend to use more open habitats preferentially when lions are in their vicinity, probably an effective anti-predator behavior against such an ambush predator. Behaviorally induced effects of lions may therefore contribute significantly to structuring African herbivore communities, and hence possibly their effects on savanna ecosystems.

    Predators influence prey populations not only through predation itself, but also indirectly through prompting changes in prey behaviour. The behavioural adjustments of prey to predation risk may carry nutritional costs, but this has seldom been studied in the wild in large mammals. Here, we studied the effects of an ambush predator, the African lion (Panthera leo), on the diet quality of plains zebras (Equus quagga) in Hwange National Park, Zimbabwe. We combined information on movements of both prey and predators, using GPS data, and measurements of faecal crude protein, an index of diet quality in the prey. Zebras which had been in close proximity to lions had a lower quality diet, showing that adjustments in behaviour when lions are within short distance carry nutritional costs. The ultimate fitness cost will depend on the frequency of predator-prey encounters and on whether bottom-up or top-down forces are more important in the prey population. Our finding is the first attempt to our knowledge to assess nutritionally mediated risk effects in a large mammalian prey species under the threat of an ambush predator, and brings support to the hypothesis that the behavioural effects of predation induce important risk effects on prey populations.

    Two phase discharge from a stratified region through single or multiple branches has been studied considerably in the past two decades. The flow distribution in the header-feeder system of CANDU(Canada Deuterium and Uranium) reactors during accident scenario is one of good examples of these applications. Recently, the passive safety feature for PWR(Pressurized Water Reactor) introduce the concept of DVI(Direct Vessel Injection) for the emergency core make up. The expected water sweep out phenomena needs careful models including the curvature effect of down comer shell and the multi branches. It has been generally accepted that the onset condition of the off take follows the 2.5 power law, but recently, Lee et al. discussed that the experimental data produced large scattering to the 2.5 power law. Also, the effect of branch angle on the onset point of off take remains still as an unsolved problem. Hwang et al produced the CANDU specific branch angles of 0, +-90, +-36, +-72. The experimental results showed severe deviation from the 2.5 power law and needs mechanistic understanding on these phenomena. In the present paper, we try to develop a general model of onset point including the branch orientation

    Being affected frequently by violent weather condition such as typhoons and regular seismic activity, the high mountains of Taiwan belong to the earth's most dynamic landscapes. In the fast-eroding mountain belt of Taiwan, hillslopes and valley systems have been reported to show a high level of coupling (Hovius et al. 2000). In the catchment of the Tachia river numerous bedrock landslides occur frequently as a result of seismic events and typhoons (Lin et al. 2006). This study attempts to take a closer look at the temporal and spatial pattern of hillslope evolution at two study sites in the upper catchement of the Tachia river. Therefore we have carried out a repeated field surveying of active slopes by means of traditional survey instruments and terrestrial laser scanning from early 2008 until late 2009 on a half year basis. Additionally, a set of aerial photos and satellite images from 1969, 1980,2001, 2004, 2007, 2008 and 2009 is used to assess the long-term and short-term changes of the river channel. Near the town of Huan Shan, the valley bottom shows elevations around 1520 m above sea level and the river is draining and upstream area of 155 km². Downstream of Huan Shan lies the confluence of the Tachia River and two of its tributaries, namely the Nanhu River and the Hehuan River. Therefore, the catchment area upstream of second study area in Sung Mao is considerably larger being of 420 km², in that place, the current level of the channel varies around 1425 m above sea level. In the two study areas strong lateral erosion has been observed. In the case of the Sung Mao study area, the latter is linked to a severe aggradation of sediments in the channel since the building of the Dechi Dam downstream. The active hillslopes have been surveyed and their reaction to the typhoons in 2008 and 2009 is studied. Rates of sediment yield from the slopes have been calculated for three periods between April 2008, November 2008, April 2009 and November 2009. Furthermore, the

We searched for genes that function in cell adhesion in GSE12452, a published transcriptomic database. We found that POSTN, which encodes periostin (POSTN, was significantly upregulated in NPC tumorigenesis. Herein, we sought to analyze the expression of POSTN and its prognostic significances in patients with NPC. Materials and methods: In this single-institution retrospective study, we determined and analyzed POSTN expression by immunohistochemistry and H-score method, respectively, in 124 patients with NPC. The results indicated that POSTN expression was correlated with the clinicopathologic features, disease-specific survival (DSS, distant metastasis-free survival (DMFS, and local recurrence-free survival (LRFS of NPC. We performed univariate and multivariate analyses to determinate the statistical significance. Results: High POSTN expression was significantly associated with lymph node metastasis

    Full Text Available Objective – To describe an inventory system that was created within the library and to show the cost-effectiveness of using the inventory system compared to the price of reacquiring mis-shelved books.Design – Bibliometric study and cost-benefit analysis.Setting – Medium-sized academic library in a rural community of the United States.Subjects – Approximately 300,000 books from LC classifications D through H, N, P and Q, representing two thirds of the library’s entire monograph collection.Methods – The library created its own electronic inventory and shelf-reading program, using a laptop computer equipped with a hand-held scanner, to scan barcodes in the stacks. Library staff used the Microsoft Access database to update two files containing a shelf-list and an active-status list while the books were scanned. The program alerted the worker if books found had an active status (i.e., Missing, Renewed, Overdue, Charged, were not in the correct order, or were not in the system. Each transaction created a log which contained a time stamp (to the second, the call number and the barcode number. It also took note of scanning errors, books that were out of order, and books that were not on a shelf-list. After a complete section was examined, a list was produced to reveal the distance of mis-shelved books from their correct location and the amount of time between each scan. The researchers used statistical analysis (using SPSS 15.0 to measure scan speed for each scan, mis-shelving rate and error distance of each mis-shelved book. In order to analyze the cost of labour to replace a book versus the cost of inventorying, the researchers estimated the salary costs of staff members involved in selection, acquisition and cataloguing. The library spent $440,000 USD in labour costs to purchase 15,000 monographs in one fiscal year (approximately $30.00 USD in labour costs per book. They multiplied this by 5300 books that were found to be “badly” mis-shelved (found beyond 25 books away from the proper position. Labour fees were used to determine costs of inventorying by calculating average scanning speed and cost per hour to pay someone to scan the entire half-million monograph collection.Main Results – It took approximately 707 hours to scan 305,000 monographs. The average (mode calculation for scans was 5 seconds for 80% of the barcodes, with an average (mean of 8.35 seconds between scans. The longest average (mean time for scanning barcodes was in the N section, followed by G, H, P, Q, D, E and F. A total of 291 books were found on the shelves with an “active” status (i.e., Charged (4, Overdue (7, Renewed (4, In Transit (24, and Missing (228. Twenty-four books with the status “Miscellaneous” (i.e., At Bindery, Call Slip, Cataloguing Review, Damaged, and Mending were also found on the shelves. Of the 15 active books in the categories “Charged”, “Overdue” and “Renewed”, ten were found in the proper position on the shelf. Of the 228 “Missing” books, 30% were scanned in the correct location, 10% were found 26 to 100 books away, and half were located over 100 books from their proper location. In addition to the books already marked as “Missing” in the catalogue, there were 516 books (.17% of the entire scanned section still not found on the shelf after three searches over a period of 6 months. Of the 291 active status books found on the shelves, 52% were reused as of July 2008. (The inventory was completed at the end of 2006. Over 36% of books mis-shelved further than 25 books from their correct location were reused. However, among all books scanned, only 17% were reused during the same time period. The researchers noted that inconsistencies between the call number as shown on the book label and how it appeared in the catalogue occurred 565 times. Of these discrepancies, 40% of the labels resulted in books being misplaced ten or fewer books away, 10% misplaced between 10 and 100 books away, and 35% misplaced more than 100 books away from the correct position. In general, 82% of mis-shelved books were found within 1 to 25 books away from their correct location. By calculating that 5300 books were mis-shelved beyond 25 books away from their proper position, labour costs were estimated to be at least $159,000 USD (5300 x $30.00 USD per book in labour costs. Costs for interlibrary loan were calculated at approximately $30.00 USD per transaction, and patron’s time wasted trying to locate misplaced books was estimated at 30 minutes per book. This was much more than the labour costs associated with scanning books, which at an average speed of 8 seconds per book and $10.00 US per hour for scanning worked out to be 2.2 cents per book, or $11,000 USD to scan the entire half-million monograph collection.Conclusion – The results appear to reveal that the labour costs for inventory control are less expensive than repurchasing or borrowing the same number of books.

    Full Text Available On expressing ourselves using songs, lyrics play a grat role, regardless the lyrics are a translated version from another language than our mother tongue. This research focuses on JKT48‘s songs lyrics, which are both Indonesian and English translation of Japanese songs sung by its sister group, AKB48. Many Indonesian listeners feel that when listening to JKT48‘s songs, they feel that the translation is weird, they cannot receive the meaning of the songs. This is because on translating AKB48‘s songs, the translator not only has to translate the words, but also to adapt the words‘ syllables with the melody. Also, Japanese language has a different structure with both Indonesian and English language, therefore, it needs more effort on understanding a translated Japanese songs. The researcher interviewed JKT48 fans in the largest JKT48 online fan forum, JKT48 no Fansu. She asked on which translation do the fans can catch the meaning better, Indonesian or English, as well as the reason why they think so. Also, she asked what suggestions do they give for the betterment of JKT48‘s translated lyrics.

    Full Text Available Abstract: Criticism and alternative education offered by Paulo Freire is very interesting to be used to analyze the problems of education in Indonesia. It must be admitted that the context behind the controversial issue of those educational thought is different from that of Indonesian, however, it must be very suitable. According to Paulo Freire, there should be no dichotomy between the goals of education and educational ways. The goal, the transformation that frees individual to be a real person, should be manifested in the extent to how education must be implemented. The purpose of exemption cannot be separated with the path that frees. In addition, Freire's educational theory remains significant in terms of its role in which education should bring up not only the understanding of the world, but also the transformation of the world. On the other hands, Indonesian national leaders, Ki Hajar Dewantara also has inherited a very important philosophy in our national education, that is ing ngarso sung tulodo, ing madyo mangun karso, tut wuri handayani which means that the front is setting as a good model, the middle is inspiring and in the back provides support.

In this study, we identified that the functional intensity of carboxyl groups on carbon nanotubes, which correspond to the water dispersity or hydrophilicity of carbon nanotubes, can induce conformational changes in the fibrinogen domains. Also, elevation of carbon nanotube density can alter the secondary structures (ie, helices and beta sheets of fibrinogen. Furthermore, fibrinogen that had been in contact with the nanoparticle material demonstrated a different pattern of heat denaturation compared with free fibrinogen as a result of a variation in hydrophilicity and concentration of carbon nanotubes. Considering the importance of interactions between carbon nanotubes and plasma proteins in the drug delivery system, this study elucidated the correlation between nanoscale physiochemical material properties of carbon nanotubes and associated structural changes in fibrinogen.Keywords: carbon nanotubes, fibrinogen, nanotoxicity, conformational change, denaturation

    Full Text Available About 20 years ago the HSRC (Human Sciences Research Council conducted an empirical investigation on the singing of psalms in three Afrikaans reformed churches. Vos and M�ller (1990 dealt with different aspects of this investigation, especially the questions of which melodies are sung in the churches, what the frequency of the use of the different psalms is, the way in which new songs are introduced, the situation in the different churches and the influence of church attendance on the love of the psalms. In an investigation undertaken in 2008 (Van Rooy 2009 these matters were investigated in the Reformed Churches in South Africa, a denomiation that introduced a new hymnal in 2003. The comparison of the two investigations revealed that the number of favourite psalms and the same psalms remained fairly constant. The acceptance of new hymns is related to a number of factors, especially the melody and the liturgical usefulness of the new hymns. The new metrical version of the psalms is still not used very frequently in the Reformed Churches in South Africa. This can partly be ascribed to the lack of structured programmes to learn the new hymns.

    Gammavoltaic was proposed by Karl Scharf in 1960. The low efficiency resulted in gammavoltaic being used as a radiation detector. In the 1990s the efficiency of gammavoltaic increased by the use of a scintillator. Gammavoltaic was further studied as a power source for spent fuel transportation and a nuclear battery in the 2000s Haneol Lee and Man-Sung Yim also suggested electricity generation system based on spent fuel stored inside the fuel pool of a nuclear power plant. This study proposed the systematic design of an electricity conversion system using CsI(Tl) scintillator and a-Si photovoltaic cell. As such, this study is selected to be a reference paper. The results of this paper indicate a self-absorption effect from the reference model. This effect is negligible while the irradiation degradation has to be considered. Two main ways to reduce radiation induced degradation are scintillator shielding and replacing scintillator material with a material having higher radiation resistance. The analysis of the scintillator used in the 'electricity generation system using gamma radiation from spent fuel' was performed to evaluate the ideal electricity generation in the reference research.

    Taikyu Ree (1902-92) and Seung Ki Li (1905-96) were the most famous and influential scientists in twentieth-century Korea. Trained at Kyoto Imperial University during the Japanese occupation period (1910-45), both followed parallel career paths until 1945 but after that year those paths began to diverge. In 1948 Taikyu Ree moved to the University of Utah where he ran an informal graduate programme to train Korea chemists during the 1950s and 1960s. He became a model scholar in pursuit of knowledge for its own sake. In 1950 Seung Ki Li moved to North Korea where he succeeded in industrialising a new synthetic fibre from polyvinyl alcohol. He became a popular hero who demonstrated the utility of science. His success also helped Kim Il Sung, North Korea dictator, to consolidate his political ideology of Self-Reliance. Despite their different career patterns in very different circumstances, they shared something common; apolitical views and commitment to their work. An investigation of the careers of these two chemists illustrates the interwoven scientific, ideological and economic developments of South and North Korea during the second half of the twentieth century.

    2014-01-01

    Humans routinely produce acoustical energy at frequencies above 6 kHz during vocalization, but this frequency range is often not represented in communication devices and speech perception research. Recent advancements toward high-definition (HD) voice and extended bandwidth hearing aids have increased the interest in the high frequencies. The potential perceptual information provided by high-frequency energy (HFE) is not well characterized. We found that humans can accomplish tasks of gender discrimination and vocal production mode discrimination (speech vs. singing) when presented with acoustic stimuli containing only HFE at both amplified and normal levels. Performance in these tasks was robust in the presence of low-frequency masking noise. No substantial learning effect was observed. Listeners also were able to identify the sung and spoken text (excerpts from “The Star-Spangled Banner”) with very few exposures. These results add to the increasing evidence that the high frequencies provide at least redundant information about the vocal signal, suggesting that its representation in communication devices (e.g., cell phones, hearing aids, and cochlear implants) and speech/voice synthesizers could improve these devices and benefit normal-hearing and hearing-impaired listeners.

    Full Text Available The song of the Brazilian population of the Humpback Whale Megaptera novaeangliae was studied in its breeding and calving ground, the Abrolhos Bank, Bahia, Brazil, from July to November 2000. Aural and spectral analyses of digital recordings were completed for approximately 20 song cycles, totaling 5 hours of song from 10 different recording events. We identified 24 note types, organized in five themes. All songs presented the same themes and the order in which they were sung did not vary. We registered the appearance of a note type and the disappearance of a phrase ending, which indicate that the song changed as the season progressed. Moreover, we detected individual variation in the way singers performed certain complex note types. As songs are transmitted culturally, it is likely that singers have different abilities to compose and/or learn new notes. If, as it has been previously suggested, 'new' songs are preferred to 'old' ones, these more able singers will be sending out information about their learning abilities that could be used by other whales to decide whether or not to interact with them.

    2018-05-17

    Age-related differences in episodic memory have been explained by a decrement in strategic encoding implementation. It has been shown in clinical populations that music can be used during the encoding stage as a mnemonic strategy to learn verbal information. The effectiveness of this strategy remains equivocal in older adults (OA). Furthermore, the impact of the emotional valence of the music used has never been investigated in this context. Thirty OA and 24 young adults (YA) learned texts that were either set to music that was positively or negatively valenced, or spoken only. Immediate and delayed recalls were measured. Results showed that: (i) OA perform worse than YA in immediate and delayed recall; (ii) sung lyrics are better remembered than spoken ones in OA, but only when the associated music is positively-valenced; (iii) this pattern is observed regardless the retention delay. These findings support the benefit of a musical encoding on verbal learning in healthy OA and are consistent with the positivity effect classically reported in normal aging. Added to the potential applications in daily life, the results are discussed with respect to the theoretical hypotheses of the mechanisms underlying the advantage of musical encoding.

    Full Text Available In 1617 the alchemist, counselor and court physician to the then recently deceased Holy Roman Emperor Rudolf II (1552-1612 published his Atalanta Fugiens (Atalanta feeing. The book fits into the general category of an ‘alchemical emblem book’, very popular in the day: it contains 50 beautiful engravings to which are assigned poetic sextets in both Latin and German. The main difference with all known similar works is that it includes a three-part canon with each engraving. According to the author, the purpose is for all of this input “to be looked at, read, meditated, understood, weighed, sung and listened to, not without a certain pleasure” (Maier 1990, 91. In this sense, this book might be interpreted as a very early example of multimedia, and as a work which requires a performative attitude and activity (in the form of singing and not merely to be read, for its original purpose to be fully accomplished. In this brief article I will describe the work, and present arguments to support my belief that it would be reasonable to conclude that it is an early form of multimedia.

    Given a large number of t-statistics, we consider the problem of approximating the distribution of noncentrality parameters (NCPs) by a continuous density. This problem is closely related to the control of false discovery rates (FDR) in massive hypothesis testing applications, e.g., microarray gene expression analysis. Our methodology is similar to, but improves upon, the existing approach by Ruppert, Nettleton, and Hwang (2007, Biometrics, 63, 483-495). We provide parametric, nonparametric, and semiparametric estimators for the distribution of NCPs, as well as estimates of the FDR and local FDR. In the parametric situation, we assume that the NCPs follow a distribution that leads to an analytically available marginal distribution for the test statistics. In the nonparametric situation, we use convex combinations of basis density functions to estimate the density of the NCPs. A sequential quadratic programming procedure is developed to maximize the penalized likelihood. The smoothing parameter is selected with the approximate network information criterion. A semiparametric estimator is also developed to combine both parametric and nonparametric fits. Simulations show that, under a variety of situations, our density estimates are closer to the underlying truth and our FDR estimates are improved compared with alternative methods. Data-based simulations and the analyses of two microarray datasets are used to evaluate the performance in realistic situations. © 2012, The International Biometric Society.

Therefore, various formulation approaches have been attempted to address these problems. In this study, we entrapped curcumin into monoolein (MO-based liquid crystalline nanoparticles (LCNs and evaluated the physicochemical properties and anticancer activity of the LCN dispersion. The results revealed that particles in the curcumin-loaded LCN dispersion were discrete and monodispersed, and that the entrapment efficiency was almost 100%. The stability of curcumin in the dispersion was surprisingly enhanced (about 75% of the curcumin survived after 45 days of storage at 40°C, and the in vitro release of curcumin was sustained (10% or less over 15 days. Fluorescence-activated cell sorting (FACS analysis using a human colon cancer cell line (HCT116 exhibited 99.1% fluorescence gating for 5 µM curcumin-loaded LCN dispersion compared to 1.36% for the same concentration of the drug in dimethyl sulfoxide (DMSO, indicating markedly enhanced cellular uptake. Consistent with the enhanced cellular uptake of curcumin-loaded LCNs, anticancer activity and cell cycle studies demonstrated apoptosis induction when the cells were treated with the LCN dispersion; however, there was neither noticeable cell death nor significant changes in the cell cycle for the same concentration of the drug in DMSO. In conclusion, entrapping curcumin into MO-based LCNs may provide, in the future, a strategy for overcoming the hurdles associated with both the stability and cellular uptake issues of the drug in the treatment of various cancers.

The physicochemical properties of the megestrol acetate solid dispersion nanoparticles were characterized using scanning electron microscopy, differential scanning calorimetry, powder X-ray diffraction, and a particle-size analyzer. The dissolution and oral bioavailability of the nanoparticles were also evaluated in rats. The mean particle size of all solid dispersion nanoparticles that were prepared was <500 nm. Powder X-ray diffraction and differential scanning calorimetry measurements showed that megestrol acetate was present in an amorphous or molecular dispersion state within the solid dispersion nanoparticles. Hydroxypropylmethyl cellulose (HPMC solid dispersion nanoparticles significantly increased the maximum dissolution when compared with polyvinylpyrrolidone K30 solid dispersion nanoparticles. The extent and rate of dissolution of megestrol acetate increased after the addition of a surfactant into the HPMC solid dispersion nanoparticles. The most effective surfactant was Ryoto sugar ester L1695, followed by d-a-tocopheryl polyethylene glycol 1000 succinate. In this study, the solid dispersion nanoparticles with a drug:HPMC:Ryoto sugar ester L1695 ratio of 1:2:1 showed >95% rapid dissolution within 30 minutes, in addition to good oral bioavailability, with approximately 4.0- and 5.5-fold higher area under the curve (0–24 hours and maximum concentration, respectively, than raw megestrol acetate powder.

Developing new strategies to improve the osteoinductive activity of bone graft substitutes is both critical and practical for clinical application. Previously, we developed novel simvastatin-encapsulating poly(lactic-co-glycolic acid microspheres (SIM/PLGA that slowly release simvastatin and enhance fracture healing. In this study, we combined SIM/PLGA with a rapidly absorbable calcium sulfate (CS bone substitute and studied the effect on bone healing in critical-sized calvarial bone defects in a rat model. The cytotoxicity and cytocompatibility of this combination was tested in vitro using lactate dehydrogenase leakage and a cell attachment assay, respectively. Combination treatment with SIM/PLGA and the CS bone substitute had no cytotoxic effect on bone marrow stem cells. Compared with the control, cell adhesion was substantially enhanced following combination treatment with SIM/PLGA and the CS bone substitute. In vivo, implantation of the combination bone substitute promoted healing of critical-sized calvarial bone defects in rats; furthermore, production of bone morphogenetic protein-2 and neovascularization were enhanced in the area of the defect. In summary, the combination of SIM/PLGA and a CS bone substitute has osteoconductive and osteoinductive properties, indicating that it could be used for regeneration

Protoporphyrin IX accumulation in the tumor cells and phototoxicity induced by PEG-Chito-5-ALA nanoparticles were assessed using CT26 cells in vitro.Results: PEG-Chito-5-ALA nanoparticles have spherical shapes with sizes diameters 200 nm. More specifically, microscopic observation revealed a core-shell structure of PEG-Chito-5-ALA nanoparticles. 1H NMR spectra showed that 5-ALA was incorporated in the core of the nanoparticles. In the absence of light irradiation, all components such as 5-ALA, empty nanoparticles, and PEG-Chito-5-ALA nanoparticles did not affect the viability of cells. However, 5-ALA or PEG-Chito-5-ALA nanoparticles induced tumor cell death under light irradiation, and the viability of tumor cells was dose-dependently decreased according to the increase in irradiation time. In particular, PEG-Chito-5-ALA nanoparticles induced increased phototoxicity and higher protoporphyrin IX accumulation into the tumor cells than did 5-ALA alone. Furthermore, PEG-Chito-5-ALA nanoparticles accelerated apoptosis/necrosis of tumor cells, compared to 5-ALA alone.Conclusion: PEG-Chito-5-ALA nanoparticles showed superior delivery capacity of 5-ALA and phototoxicity against tumor cells.

    The operatic singing technique is frequently used in classical music. Several acoustical parameters of this specific technique have been studied but how these parameters combine remains unclear. This study aims to further characterize the Western operatic singing technique by observing the effects of melody and technique on acoustical and musical parameters of the singing voice. Fifty professional singers performed two contrasting melodies (popular song and romantic melody) with two vocal techniques (with and without operatic singing technique). The common quality parameters (energy distribution, vibrato rate, and extent), perturbation parameters (standard deviation of the fundamental frequency, signal-to-noise ratio, jitter, and shimmer), and musical features (fundamental frequency of the starting note, average tempo, and sound pressure level) of the 200 sung performances were analyzed. The results regarding the effect of melody and technique on the acoustical and musical parameters show that the choice of melody had a limited impact on the parameters observed, whereas a particular vocal profile appeared depending on the vocal technique used. This study confirms that vocal technique affects most of the parameters examined. In addition, the observation of quality, perturbation, and musical parameters contributes to a better understanding of the Western operatic singing technique. Copyright © 2014 The Voice Foundation.

  14. Possibilities and Limitations of Applying Software Reliability Growth Models to Safety- Critical Software

    2006-01-01

    As digital systems are gradually introduced to nuclear power plants (NPPs), the need of quantitatively analyzing the reliability of the digital systems is also increasing. Kang and Sung identified (1) software reliability, (2) common-cause failures (CCFs), and (3) fault coverage as the three most critical factors in the reliability analysis of digital systems. For the estimation of the safety-critical software (the software that is used in safety-critical digital systems), the use of Bayesian Belief Networks (BBNs) seems to be most widely used. The use of BBNs in reliability estimation of safety-critical software is basically a process of indirectly assigning a reliability based on various observed information and experts' opinions. When software testing results or software failure histories are available, we can use a process of directly estimating the reliability of the software using various software reliability growth models such as Jelinski- Moranda model and Goel-Okumoto's nonhomogeneous Poisson process (NHPP) model. Even though it is generally known that software reliability growth models cannot be applied to safety-critical software due to small number of expected failure data from the testing of safety-critical software, we try to find possibilities and corresponding limitations of applying software reliability growth models to safety critical software

  15. Signal-to-background-ratio preferences of normal-hearing listeners as a function of music

    Barrett, Jillian G.

    2005-04-01

    The primary purpose of speech is to convey a message. Many factors affect the listener's overall reception, several of which have little to do with the linguistic content itself, but rather with the delivery (e.g., prosody, intonation patterns, pragmatics, paralinguistic cues). Music, however, may convey a message either with or without linguistic content. In instances in which music has lyrics, one cannot assume verbal content will take precedence over sonic properties. Lyric emphasis over other aspects of music cannot be assumed. Singing introduces distortion of the vowel-consonant temporal ratio of speech, emphasizing vowels and de-emphasizing consonants. The phonemic production alterations of singing make it difficult for even those with normal hearing to understand the singer. This investigation was designed to identify singer-to-background-ratio (SBR) prefer- ences for normal hearing adult listeners (as opposed to SBR levels maxi-mizing speech discrimination ability). Stimuli were derived from three different original songs, each produced in two different genres and sung by six different singers. Singer and genre were the two primary contributors to significant differences in SBR preferences, though results clearly indicate genre, style and singer interact in different combinations for each song, each singer, and for each subject in an unpredictable manner.

Given the amplitude of the topic and the ungraspable nature of such fields as popular culture and pop-Shakespeare, the author does not (and cannot aim to be exhaustive, but rather addresses the issue by selecting four characters, Juliet, Ophelia, Cordelia, and Lady Macbeth, whose musical alter egos will be analysed by the close reading of a selection of songs written and sung by rock singer-songwriters chosen for their representativeness and their popularity. The analysis will try and answer the following questions: which aspects of the dramatic characters are highlighted or, on the contrary, omitted in the songs? What is the function of this musical use of Shakespeare's work? Through their musical identity, do these female characters reinforce or undermine the socio-cultural and psychological oppression of women characteristic of a patriarchal culture? What can the role of these musical offshoots play in the study of Shakespeare's reception?

    2003-04-01

    The humpback whale song has been described and investigated since the early 1970s. Much has been learned about the humpback whale social structure, but the understanding of the song and its function remains elusive. The hierarchical nature of the song structure was described early on: Songs can be sung for a long period, apparently by males, and primarily during the mating season. However, singers also become physically competitive, suggesting alternative mating strategies. There are a number of unique structural features of song. Its structure evolves over time and combination. The nature of song evolution strongly implies cultural transmission. Song structure appears to be shared within an entire population, even though there appears to be little interchange of individuals between sub populations. Despite over thirty years of inquiry there are still numerous unanswered questions: Why is the song structure so complex? Is song a sexual advertisement, an acoustic space mediation mechanism, or both? How do females choose mates, or do they? What drives song evolution, and why is there so much variation in the rate of change? Are there nonreproductive functions of song? What prompts a male to begin or end singing? Our current understanding and the outstanding questions yet to be answered will be reviewed.

    Brain damage causing acquired amusia disrupts the functional music processing system, creating a unique opportunity to investigate the critical neural architectures of musical processing in the brain. In this longitudinal fMRI study of stroke patients (N = 41) with a 6-month follow-up, we used natural vocal music (sung with lyrics) and instrumental music stimuli to uncover brain activation and functional network connectivity changes associated with acquired amusia and its recovery. In the acute stage, amusic patients exhibited decreased activation in right superior temporal areas compared to non-amusic patients during instrumental music listening. During the follow-up, the activation deficits expanded to comprise a wide-spread bilateral frontal, temporal, and parietal network. The amusics showed less activation deficits to vocal music, suggesting preserved processing of singing in the amusic brain. Compared to non-recovered amusics, recovered amusics showed increased activation to instrumental music in bilateral frontoparietal areas at 3 months and in right middle and inferior frontal areas at 6 months. Amusia recovery was also associated with increased functional connectivity in right and left frontoparietal attention networks to instrumental music. Overall, our findings reveal the dynamic nature of deficient activation and connectivity patterns in acquired amusia and highlight the role of dorsal networks in amusia recovery.

    A classic observation in neurology is that aphasics can sing words they cannot pronounce otherwise. To further assess this claim, we investigated the production of sung and spoken utterances in eight brain-damaged patients suffering from a variety of speech disorders as a consequence of a left-hemisphere lesion. In Experiment 1, the patients were tested in the repetition and recall of words and notes of familiar material. Lyrics of familiar songs, as well as words of proverbs and prayers, were not better pronounced in singing than in speaking. Notes were better produced than words. In Experiment 2, the aphasic patients repeated and recalled lyrics from novel songs. Again, they did not produce more words in singing than in speaking. In Experiment 3, when allowed to sing or speak along with an auditory model while learning novel songs, aphasics repeated and recalled more words when singing than when speaking. Reduced speed or shadowing cannot account for this advantage of singing along over speaking in unison. The results suggest that singing in synchrony with an auditory model--choral singing--is more effective than choral speech, at least in French, in improving word intelligibility because choral singing may entrain more than one auditory-vocal interface. Thus, choral singing appears to be an effective means of speech therapy.

    Full Text Available This study aimed at analyzing the bibliometric characteristics and content of medical articles from North Korea in PubMed and characterizing the patterns of international cooperation of medical researchers in North Korea. We hypothesized that the number of publications from North Korea in PubMed has increased recently as a result of active cooperation with foreign researchers. PubMed was searched on July 19, 2017 using the search term “(North Korea [Affiliation] OR Democratic People’s Republic of Korea [Affiliation] OR DPRK [Affiliation].” The content of medical articles was analyzed and cooperative work with foreign researchers was noted. The number of medical articles in PubMed through July 2017 was 16, of which 2 were by North Korean authors only. From the content of these articles, it was found that researchers in top-notch institutions, including Kim Il Sung University, can access the internet, and that a dental caries prevention program supported by Finland has been in place for more than 10 years. The number of publications from North Korea in PubMed has increased recently, although the amount is still very small. Providing internet access to North Korean researchers will accelerate their submissions to international journals.

    Full Text Available Difficulties with temporal coordination or sequencing of speech movements are frequently reported in aphasia patients with concomitant apraxia of speech (AOS. Our major objective was to investigate the effects of specific rhythmic-melodic voice training on brain activation of those patients. Three patients with severe chronic nonfluent aphasia and AOS were included in this study. Before and after therapy, patients underwent the same fMRI procedure as 30 healthy control subjects in our prestudy, which investigated the neural substrates of sung vowel changes in untrained rhythm sequences. A main finding was that post-minus pretreatment imaging data yielded significant perilesional activations in all patients for example, in the left superior temporal gyrus, whereas the reverse subtraction revealed either no significant activation or right hemisphere activation. Likewise, pre- and posttreatment assessments of patients’ vocal rhythm production, language, and speech motor performance yielded significant improvements for all patients. Our results suggest that changes in brain activation due to the applied training might indicate specific processes of reorganization, for example, improved temporal sequencing of sublexical speech components. In this context, a training that focuses on rhythmic singing with differently demanding complexity levels as concerns motor and cognitive capabilities seems to support paving the way for speech.

  5. White-throated sparrows alter songs differentially in response to chorusing anurans and other background noise.

    Animals can use acoustic signals to attract mates and defend territories. As a consequence, background noise that interferes with signal transmission has the potential to reduce fitness, especially in birds that rely on song. While much research on bird song has investigated vocal flexibility in response to urban noise, weather and other birds, the possibility of inter-class acoustic competition from anurans has not been previously studied. Using sound recordings from central Ontario wetlands, we tested if white-throated sparrows (Zonotrichia albicolis) make short-term changes to their singing behaviour in response to chorusing spring peepers (Pseudacris crucifer), as well as to car noise, wind and other bird vocalizations. White-throated sparrow songs that were sung during the spring peeper chorus were shorter with higher minimum frequencies and narrower bandwidths resulting in reduced frequency overlap. Additionally, sparrows were less likely to sing when car noise and the vocalizations of other birds were present. These patterns suggest that birds use multiple adjustment strategies. This is the first report to demonstrate that birds may alter their songs differentially in response to different sources of noise. This article is part of a Special Issue entitled: insert SI title.

Despite their potential, the interaction between MSCs and T cells, key players in the pathophysiology of autoimmune diseases, is not yet well understood, thereby preventing further clinical progress. A major obstacle is the highly heterogeneous nature of MSCs in vitro. Unfortunately, bulk assays do not provide information with regard to cell–cell contributions that may play a critical role in the overall cellular response. To address these issues, we investigated the interaction between smaller subsets of MSCs and CD4 T cells in a microwell array. We demonstrate that MSCs appear capable of modulating the T cell proliferation rate in response to persistent cell–cell interactions, and we anticipate the use of our microwell array in the classification of subpopulations within MSCs, ultimately leading to specific therapeutic interventions.Keywords: mesenchymal stem cell, T cell, microwell array

    Highlights: •A review of heat transfer characteristics for water flow in helically coiled tubes are conducted. •An assessment of heat transfer models under different heat transfer modes in helically coiled tubes are performed. •This work could provide references for the use of the correlations and for further studies. -- Abstract: This paper presents an assessment of the heat transfer models under different heat transfer modes for water flow in helically coiled tubes based on the compiled datasets from the reviewed literatures. For single phase flow, most of the correlations of the heat transfer coefficient can fit well to the experiments. The correlations of Xin-Ebadian, Dravid and Kalb-Seader for laminar flow and those of Seban-McLaughlim, Mori-Nakayama, Xin-Ebadian, Hardik, Rogers-Mayhew, Mikaila-Poskas and El-Genk-Schriener for turbulent flow are recommended. For flow boiling heat transfer, Steiner-Taborek correlation could be utilized to predict the boiling heat transfer coefficients in helically coiled tubes for a relatively wide range of parameters. For dryout quality, the correlations of Hwang et al. and Santini et al. give relatively better predictions than others. However, more accurate correlations for flow boiling heat transfer coefficient and dryout quality need to be developed based on further investigations with wider parameter ranges in the future. The present work could provide references for the investigators for future uses of those correlations and for performing further investigations on the heat transfer characteristics of water flow in helically coiled tubes.

    By using the ILSI network in Asia, we are holding a session focused on food safety programs in several Asian areas. In view of the external environment, it is expected to impact the global food system in the near future, including the rapid increase in food demand and in public health services due to population growth, as well as the threats to biosecurity and food safety due to the rapid globalization of the food trade. Facilitating effective information sharing holds promise for the activation of the food industry. At this session, Prof. Hwang shares the current situation of Food Safety and Sanitation Regulations in Taiwan. Dr. Liu provides a talk on the role of risk assessment in food regulatory control focused on aluminum-containing food additives in China. After the JECFA evaluation of aluminum-containing food additives in 2011, each country has carried out risk assessment based on dietary intake surveys. Ms. Chan reports on the activities of a working group on Food Standards Harmonization in ASEAN. She also explains that the ILSI Southeast Asia Region has actively supported the various ASEAN Working Groups in utilizing science to harmonize food standards. Prof. Park provides current research activities in Korea focused on the effect of climate change on food safety. Climate change is generally seen as having a negative impact on food security, particularly in developing countries. We use these four presentations as a springboard to vigorous discussion on issues related to Food Safety in Asia.

    The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Female adolescent orphans are particularly in jeopardy of contracting HIV due to disadvantages including extreme poverty, low education, and the absent of parental oversight which can lead to higher risk-taking sexual behaviors. By understanding where girls receive education about HIV and who they rely on for information, organizations can effectively modify existing programs to better target this at-risk population. For this study a household survey was conducted which included 216 orphans and 324 non-orphans (n=540), aged 12-17 years, in the resource-poor setting of Hwange District, Zimbabwe. The aims of this article were to examine the differences between orphans and non-orphans in HIV prevention message exposure, level of motivation for learning about HIV, and communication with caregivers about safe sex. The household survey revealed that younger orphans, aged 12-15 years, were more motivated to learn about HIV and had greater HIV messaging exposure in school than non-orphans. These exposure and differences in the levels of motivation between groups dissipated at older ages. Our research also discovered less caregiver communication among orphans than non-orphans. Our findings suggest that HIV programs targeting orphans need to do a better job at keeping older orphans interested in HIV prevention at a time when it matters most. Furthermore, intervention strategies that provide caregiver support are instrumental in effectively delivering prevention messages to girls at home.

    Genetic modification is an indispensable tool to study gene function in normal development and disease. The recent breakthrough of creating human induced pluripotent stem cells (iPSCs) by defined factors (Takahashi et al., Cell 131:861-872, 2007) provides a renewable source of patient autologous cells that not only retain identical genetic information but also give rise to many cell types of the body including neurons and glia. Meanwhile, the rapid advancement of genome modification tools such as gene targeting by homologous recombination (Capecchi, Nat Rev Genet 6:507-512, 2005) and genome editing tools such as CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas (CRISPR-associated) system, TALENs (Transcription activator-like effector nucleases), and ZFNs (Zinc finger nucleases) (Wang et al., Cell 153:910-918, 2013; Mali et al., Science 339:823-826, 2013; Hwang et al., Nat Biotechnol 31:227-229, 2013; Friedland et al., Nat Methods 10(8):741-743, 2013; DiCarlo et al., Nucleic Acids Res 41:4336-4343, 2013; Cong et al., Science 339:819-823, 2013) has greatly accelerated the development of human genome manipulation at the molecular level. This chapter describes the protocols for making neural lineage reporter lines using homologous recombination and the CRISPR/Cas system-mediated genome editing, including construction of targeting vectors, guide RNAs, transfection into hPSCs, and selection and verification of successfully targeted clones. This method can be applied to various needs of hPSC genetic engineering at high efficiency and high reliability.

    Full Text Available The purpose of international conflict-resolution efforts is, in the short term, to bring an end to violent armed conflict, and, in the medium to longer term, to prevent the revival of conflict. However, at least one of the mechanisms often utilised in conflict resolution and peace agreements, power-sharing, may not only prove problematic in early negotiation and implementation, but may potentially be at odds with the longer-term goal of preventing resurgence of conflict. Why might this be the case? Longer-term peacebuilding seeks to prevent conflict in part by building strong and sustainable states. Such states should be able to avoid reverting to armed conflict because they would be more responsive to grievances and more effective in dealing with violent dissent. However, power-sharing arrangements may undermine such efforts by placing in power individuals and groups not fully committed to, or unable to take part in, governance for the benefit of the entire populace; in part because it necessarily places in power those who have engaged in significant violence to achieve their ends. This is likely to create less democratic states, although we do not insist that democracy is or should be the only goal of peacebuilders. Rather, we suggest that powersharing arrangements may tend not only towards undemocratic states, but towards states which are not responsive to the needs of the citizenry for security in ways which may undermine human security and state legitimacy. Ziel internationaler Bemühungen zur Konfliktlösung ist es auf kurze Sicht, gewaltsame bewaffnete Konflikte zu beenden, auf mittlere oder lange Sicht, das Wiederaufleben von Konflikten zu verhindern. Zumindest ein Mittel, das häufig in Konfliktlösungs- und Friedensabkommen eingesetzt wird, die Machtteilung, kann sich allerdings im frühen Verhandlungs- und Umsetzungsstadium als problematisch erweisen und dem langfristigen Ziel, das Wiederaufflammen des Konflikts zu verh

    Full Text Available Bruno Kreisky, chancelier autrichien de 1970 à 1983 a, tout au long de sa carrière politique, manifesté un grand intérêt pour la construction de la paix et l’apaisement des conflits. Sa première action d’envergure eut lieu à partir de 1959, lorsqu’il devint ministre des Affaires étrangères autrichiennes et qu’il décida de s’emparer de la question du Tyrol méridional qui empoisonnait les relations entre l’Autriche et l’Italie depuis la fin de la Seconde Guerre mondiale. Pour tenter de mettre un terme à ce conflit, Kreisky privilégia la discussion avec l’Italie directement, puis ensuite par l’intermédiaire des Nations unies, lorsque les négociations bilatérales aboutirent à une impasse. Si Kreisky manifestait un tel intérêt pour la construction de la paix, c’est parce qu’il considérait que paix et démocratie étaient intimement liées. C’est également cette conviction qui le poussa à vouloir apaiser un conflit qui se déroula sur le territoire autrichien lui-même. Il s’agit du conflit à propos de la mise en place de panneaux bilingues en Carinthie. Dans ce cas, malgré ses efforts, Kreisky ne parvint pas à apaiser les opposants à la loi sur les panneaux bilingues qui refusaient et refusent toujours à l’heure actuelle de voir ériger des panneaux en allemand et en slovène dans les régions de Carinthie à forte minorité slovène.Bruno Kreisky, österreichischer Bundeskanzler von 1970 bis 1983, engagierte sich überaus stark in der Frage der Lösung (internationaler Konflikte. 1959 österreichischer Außenminister geworden, war der erste Konflikt, mit dem er sich auseinanderzusetzen hatte, die sog. „Südtirolfrage“.

    The singing of song birds can form complex signal systems comprised of numerous subunits sung with distinct combinatorial properties that have been described as syntax-like. This complexity has inspired inquiries into similarities of bird song to human language; but the quantitative analysis and description of song sequences is a challenging task. In this study, we analysed song sequences of common nightingales (Luscinia megarhynchos) by means of a network analysis. We translated long nocturnal song sequences into networks of song types with song transitions as connectors. As network measures, we calculated shortest path length and transitivity and identified the 'small-world' character of nightingale song networks. Besides comparing network measures with conventional measures of song complexity, we also found a correlation between network measures and age of birds. Furthermore, we determined the numbers of in-coming and out-going edges of each song type, characterizing transition patterns. These transition patterns were shared across males for certain song types. Playbacks with different transition patterns provided first evidence that these patterns are responded to differently and thus play a role in singing interactions. We discuss potential functions of the network properties of song sequences in the framework of vocal leadership. Network approaches provide biologically meaningful parameters to describe the song structure of species with extremely large repertoires and complex rules of song retrieval.

    Full Text Available Shakespeare thrives not only in the theatre, but also through what Bolter and Grusin call remediation. This article analyses how opera and musical reread Elizabethan drama shifting from spoken to sung discourse and travelling transnationally, temporally and across genres. Its main approach is comparative and relies on the history of mentalities. Rereading is dictated by cultural context, the conventions of the lyrical theatre, social and political factors and reception. Gender is reread in Bellini‘s I Capuleti e i Montecchi and in Britten‘s A Midsummer Night‟s Dream, and religion - in Gounod‘s Roméo et Juliette and Bernstein‘s West Side Story. Cultural and historical barriers enjoin recontextualisation: the English, French and Welsh verbal fun in The Merry Wives is metamorphosed into Germ-Italian in Salieri‘s Vienna, while prayer is bowdlerised in Bentoiu‘s Hamlet written in communist Romania. Porter‘s Kiss Me, Kate rewrites The Taming of the Shrew in a post-modern musical avant la lettre featuring the cast of a theatre company on- and off-stage. However, operas such as Rossini‘s Otello or Thomas‘s Hamlet are shown to have almost replaced Shakespeare‘s initial message. The article emphasises the idea that operations of rereading and rewriting, in a musical context, significantly enrich the ample panoply of Shakespearean adaptations.

The aim of our study was to systematically review the pharmacological effects of G-Rk1. We utilized and manually searched eight databases to select in vivo and in vitro original studies that provided information about biological, pharmaceutical effects of G-Rk1 and were published up to July 2017 with no restriction on language or study design. Out of the 156 papers identified, we retrieved 28 eligible papers in the first skimming phase of research. Several articles largely described the G-Rk1 anti-cancer activity investigating “cell viability”, “cell proliferation inhibition”, “apoptotic activity”, and “effects of G-Rk1 on G1 phase and autophagy in tumor cells” either alone or in combination with G-Rg5. Others proved that it has antiplatelet aggregation activities, anti-inflammatory effects, anti-insulin resistance, nephroprotective effect, antimicrobial effect, cognitive function enhancement, lipid accumulation reduction and prevents osteoporosis. In conclusion, G-Rk1 has a significant anti-tumor effect on liver cancer, melanoma, lung cancer, cervical cancer, colon cancer, pancreatic cancer, gastric cancer, and breast adenocarcinoma against in vitro cell lines. In vivo experiments are further warranted to confirm these effects.

Microflora activation and a stepwise mechanism for drug release were postulated. Consequently, the optimized DL-CDDS showed drug release in a controlled manner by inhibiting drug release in the stomach and intestine, but releasing the drug gradually in the colon (approximately 40% at 10 hours and 92% at 24 hours in CTNase-supplemented simulated colonic fluid, indicating its feasibility as a novel platform for CDD.

    Full Text Available In the Jewish tradition, the Tu Bishvat, or “Festivity of the Trees”, at the end of January is the occasion to challenge the harshness of winter, celebrate nature’s vitality and fruitfulness, and to admire the articulate relationship between man and environment. All those aspects, related to the mythical and spiritual concept of the sacredness of the Land of Israel, are rooted in an antique tradition expressed in Deuteronomy: 20, 19 “When thou shalt besiege a city […], thou shalt not destroy the trees”. A similar concept is announced hundreds years later in a mysterious text, called Perek Shira, imbedded as part of the Tu Bishvat synagogue recitation. At the beginning of the 19th century, the famous Hassidic Rebbe, Nachman from Breslav, meditated intensely about the insolvable bonds existing between human being and the plant’s world. In his book Likkutei Moharan he persuades his disciples: “You should know that every plant and plant/ has its own and specific melody”. In the seventies, this Nigun becomes a very popular and beloved song by the talented Israeli chansonnière Naomi Shemer, born in kibbutz Degania, near the Lake of Galilee. The song is sung in public, at the Shabbat table, in religious and secular occasions, embracing biblical memory, spiritual history and a new musical approach.

    Full Text Available Mit der gegenwärtigen Diskussion um Mediatisierung und Digitalisierung ist die Forderung verbunden, der Medienbildung und/oder der informatischen Bildung ein größeres Gewicht in der schulischen Bildung zu verschaffen. Dies legt die Frage nahe, wie ein produktives Verhältnis zwischen beiden gestaltet werden sollte und wie beide am besten zu einer zeitgemäßen Bildung beitragen können. Bei entsprechenden Überlegungen spielen unter anderem Entwicklungen eine Rolle, die sich seit frühen Forderungen nach einer Computerbildung im Verhältnis zur damaligen Medienerziehung herausgebildet haben. In dem vorliegenden Beitrag werden solche Entwicklungen skizziert und Schlussfolgerungen für die gegenwärtige Diskussion formuliert. Dabei kommen unterschiedliche Auffassungen zur bildungsbezogenen Auseinandersetzung mit Medien sowie mit Informations- und Kommunikationstechnologien in den Blick. Für das Verhältnis von Medienbildung und informatischer Bildung ergibt sich als zentrale Schlussfolgerung, dass sowohl eine Integration der informatischen Bildung in die Medienbildung als auch eine umgekehrte Lösung unangemessen erscheint, wiewohl beide Bereiche auf Anteile aus dem jeweils anderen Bereich angewiesen sind. Danach werden für eine Medienbildung mit informatischen Anteilen ein geeigneter Medienbegriff und eine tragfähige Bildungsauffassung sowie ein Ansatz zu einem inhaltlich-thematischen Kompetenzrahmen beschrieben. Überlegungen zur schulischen Umsetzung schließen den Beitrag ab.

These impairments, associated with acquired amusia, can be highly selective, affecting only music perception (i.e., receptive abilities/functions or expression (music production abilities, and some patients report that these may dramatically influence their emotional state. The aim of this study was to systematically test both the melodic and rhythmic domains of music perception and expression in left- and right-sided stroke patients compared to healthy subjects. Music perception was assessed using rhythmic and melodic discrimination tasks, while tests of expressive function involved the vocal or instrumental reproduction of rhythms and melodies. Our approach revealed deficits in receptive and expressive functions in stroke patients, mediated by musical expertise. Those patients who had experienced a short period of musical training in childhood and adolescence performed better in the receptive and expressive subtests compared to those without any previous musical training. While discrimination of specific musical patterns was unimpaired after a right-sided stroke, patients with a left-sided stroke had worse results for fine melodic and rhythmic analysis. In terms of expressive testing, the most consistent results were obtained from a test that required patients to reproduce sung melodies. This implies that the means of investigating production abilities can impact the identification of deficits.

    The effect of high-temperature growth on the crystalline quality and surface morphology of GaN and Al x Ga1- x N grown by ammonia-based metalorganic molecular-beam epitaxy (NH3-MOMBE) has been investigated as a means of producing atomically smooth films suitable for device structures. The effects of V/III ratio on the growth rate and surface morphology are described herein. The crystalline quality of both GaN and AlGaN was found to mimic that of the GaN templates, with (002) x-ray diffraction (XRD) full-widths at half- maximum (FWHMs) of ~350 arcsec. Nitrogen-rich growth conditions have been found to provide optimal surface morphologies with a root-mean-square (RMS) roughness of ~0.8 nm, yet excessive N-rich environments have been found to reduce the growth rate and result in the formation of faceted surface pitting. AlGaN exhibits a decreased growth rate, as compared with GaN, due to increased N recombination as a result of the increased pyrolysis of NH3 in the presence of Al. AlGaN films grown directly on GaN templates exhibited Pendellösung x-ray fringes, indicating an abrupt interface and a planar AlGaN film. AlGaN films grown for this study resulted in an optimal RMS roughness of ~0.85 nm with visible atomic steps.

    Full Text Available The current study is a postmodern appraisal of Bob Dylan’s artistic career and vocal gestures to examine the way melody in popular music works in relation to speech and singing, the grand and the ordinary. It historicizes Bob Dylan’s protest music of the 1960s within the paradigm of folk music culture. Dylan’s music is full of riffs, blues sequences, and pentatonic melodies—all heavily part and parcel of blues, folk, gospel, and country music. It is the music that dwells on the pleasures of repetition, of circularity, and of the recurring familiar tune integrated within Dylanesque poetics of rhyme delivered with his idiosyncratic, deep and intense range of voices. Dylan is the official son of the legacies of social, communal, and ritual music-making that mirrors contemporary pop and rock back to folk and blues, street-sung broadsides and work songs, the melodies of medieval troubadours, and the blessed rhythms of Christianity and Judaism. The study is an attempt to illustrate how musicology and ethnomusicology in particular can contribute to understanding Dylan as a ‘performing artist’ within the postmodern paradigm. Thus, the study seeks to establish Dylan as a phenomenal, prolific postmodernist artist, as well as an anarchist. The power and originality of Dylan’s music constitute a prima facie case that his performances should be considered postmodernist art.

    Full Text Available Summary: Haplo-insufficiency of telomerase genes in humans leads to telomere syndromes such as dyskeratosis congenital and idiopathic pulmonary fibrosis. Generation of pluripotent stem cells from telomerase haplo-insufficient donor cells would provide unique opportunities toward the realization of patient-specific stem cell therapies. Recently, pluripotent human embryonic stem cells (ntESCs have been efficiently achieved by somatic cell nuclear transfer (SCNT. We tested the hypothesis that SCNT could effectively elongate shortening telomeres of telomerase haplo-insufficient cells in the ntESCs with relevant mouse models. Indeed, telomeres of telomerase haplo-insufficient (Terc+/− mouse cells are elongated in ntESCs. Moreover, ntESCs derived from Terc+/− cells exhibit naive pluripotency as evidenced by generation of Terc+/− ntESC clone pups by tetraploid embryo complementation, the most stringent test of naive pluripotency. These data suggest that SCNT could offer a powerful tool to reprogram telomeres and to discover the factors for robust restoration of telomeres and pluripotency of telomerase haplo-insufficient somatic cells. : Sung et al. demonstrate in a mouse model that telomeres of telomerase haplo-insufficient cells can be elongated by somatic cell nuclear transfer.

    Phenotypic characters with a complex physical basis may have a correspondingly complex evolutionary history. Males in the "bee" hummingbird clade court females with sound from tail-feathers, which flutter during display dives. On a phylogeny of 35 species, flutter sound frequency evolves as a gradual, continuous character on most branches. But on at least six internal branches fall two types of major, saltational changes: mode of flutter changes, or the feather that is the sound source changes, causing frequency to jump from one discrete value to another. In addition to their tail "instruments," males also court females with sound from their syrinx and wing feathers, and may transfer or switch instruments over evolutionary time. In support of this, we found a negative phylogenetic correlation between presence of wing trills and singing. We hypothesize this transference occurs because wing trills and vocal songs serve similar functions and are thus redundant. There are also three independent origins of self-convergence of multiple signals, in which the same species produces both a vocal (sung) frequency sweep, and a highly similar nonvocal sound. Moreover, production of vocal, learned song has been lost repeatedly. Male bee hummingbirds court females with a diverse, coevolving array of acoustic traits. © 2018 The Author(s).

    This study explores thermoelectrics as a viable option for small-scale solar thermal applications. Thermoelectric technology is based on the Seebeck effect, which states that a voltage is induced when a temperature gradient is applied to the junctions of two differing materials. This research proposes to analyze, validate, simulate, and optimize a prototype solar thermoelectric generator (STEG) model in order to increase efficiency. The intent is to further develop STEGs as a viable and productive energy source that limits pollution and reduces the cost of energy production. An empirical study (Kraemer et al. in Nat Mater 10:532, 2011) on the solar thermoelectric generator reported a high efficiency performance of 4.6%. The system had a vacuum glass enclosure, a flat panel (absorber), thermoelectric generator and water circulation for the cold side. The theoretical and numerical approach of this current study validated the experimental results from Kraemer's study to a high degree. The numerical simulation process utilizes a two-stage approach in ANSYS software for Fluent and Thermal-Electric Systems. The solar load model technique uses solar radiation under AM 1.5G conditions in Fluent. This analytical model applies Dr. Ho Sung Lee's theory of optimal design to improve the performance of the STEG system by using dimensionless parameters. Applying this theory, using two cover glasses and radiation shields, the STEG model can achieve a highest efficiency of 7%.

    Opera and chant singers learn to effectively use aerodynamic components by breathing exercises during their education. Aerodynamic components, including subglottic air pressure and airflow, deteriorate in voice disorders. This study aimed to evaluate the changes in aerodynamic parameters and supraglottic structures of men and women with different vocal registers who are in an opera and chant education program. Vocal acoustic characteristics, aerodynamic components, and supraglottic structures were evaluated in 40 opera and chant art branch students. The majority of female students were sopranos, and the male students were baritone or tenor vocalists. The acoustic analyses revealed that the mean fundamental frequency was 152.33 Hz in the males and 218.77 Hz in the females. The estimated mean subglottal pressures were similar in females (14.99 cmH 2 O) and in males (14.48 cmH 2 O). Estimated mean airflow rates were also similar in both groups. The supraglottic structure compression analyses revealed partial anterior-posterior compressions in 2 tenors and 2 sopranos, and false vocal fold compression in 2 sopranos. Opera music is sung in high-pitched sounds. Attempts to sing high-pitched notes and frequently using register transitions overstrain the vocal structures. This intense muscular effort eventually traumatizes the vocal structures and causes supraglottic activity. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Clinical nurses play a vital role in clinical practice education; thus, it is necessary to help clinical nurses have teaching efficacy through the development and application of systematic education programs. To identify nurses' teaching efficacy for clinical education and analyze the influencing factors of teaching efficacy. The study used a cross-sectional design. We used a convenience sample of 263 nurses from two hospitals. Teaching efficacy, general characteristics, and perception of clinical practice education were collected via self-reported questionnaires. Teaching efficacy was measured using Hwang's (2006) questionnaire, while perception of clinical practice education was measured using the Clinical Nurse Teacher Survey developed by Nishioka et al. (2014). Participants completed the questionnaire directly. The collected data were then analyzed using descriptive statistics, t-tests, ANOVAs, and multiple regression analysis with PASW Statistics 18.0. The mean total score of teaching efficacy was 72.5 (range 21-105). The leadership for students subscale had the highest score (3.56±0.59). The factors influencing teaching efficacy were length of clinical career (β=0.26, pteaching efficacy in nurses. Based on these results, nursing educators might need to develop greater confidence in their knowledge and enhance control of their teaching strategies. Nursing schools and hospitals might need to provide greater support and educational opportunities to nurse clinical practice instructors. Furthermore, constructing a system of cooperation between these colleges and educational hospitals, developing programs to enhance teaching efficacy, and identifying the clinical instructor's role are all necessary to promote clinical practice education.

    To determine the HIV prevalence and extent of engagement with HIV prevention and care among a representative sample of Zimbabwean sex workers working in Victoria Falls, Hwange and Mutare. Respondent driven sampling (RDS) surveys conducted at each site. Sex workers were recruited using respondent driven sampling with each respondent limited to recruiting 2 peers. Participants completed an interviewer-administered questionnaire and provided a finger prick blood sample for HIV antibody testing. Statistical analysis took account of sampling method. 870 women were recruited from the three sites. HIV prevalence was between 50 and 70%. Around half of those confirmed HIV positive were aware of their HIV status and of those 50-70% reported being enrolled in HIV care programmes. Overall only 25-35% of those with laboratory-confirmed HIV were accessing antiretroviral therapy. Among those reporting they were HIV negative, 21-28% reported having an HIV test in the last 6 months. Of those tested HIV negative, most (65-82%) were unaware of their status. Around two-thirds of sex workers reported consistent condom use with their clients. As in other settings, sex workers reported high rates of gender based violence and police harassment. This survey suggests that prevalence of HIV is high among sex workers in Zimbabwe and that their engagement with prevention, treatment and care is sub-optimal. Intensifying prevention and care interventions for sex workers has the potential to markedly reduce HIV and social risks for sex workers, their clients and the general population in Zimbabwe and elsewhere in the region.

    Herbal therapies gained much popularity among the general public, but compared to therapies approved by official authorities, toxicological studies are frequently not available for them. Hence, there may be inherent risks and the kidneys may be especially vulnerable to toxic effects. Herbs may induce nephrotoxicity by induction of apoptosis. High oxalate contents in Star fruit (Averrhoa carambola L.) may induce acute nephropathy. Triptolide from Thunder God Vine (Triperygium wilfordii Hook) is a diterpenoid epoxide with induces reactive oxygen species and nephrotubular apoptosis. Cranberry juice is discussed as promoter of kidney stone formation (nephrolithiasis). Abuse of guaifenesin from Roughbark (Guaicum officinale L.) increases stone formation. Aristolochia acids from Aristolochia fangchi Y.C.Wu ex L.D. Chow & S.M. Hwang causes the well-known aristolochic acid nephropathy and carcinogenesis by DNA adduct formation. Carboxyatractyloside from Impila (Callilepsis laureola DC.) inhibits mitochondrial ATP synthesis. Acute allergic interstitial nephritis was diagnosed after intake of Peruvian Cat's claw (Uncaria tomentosa Willd. DC.). Whether or not Willow Bark (Salix alba L.) induces analgesic nephropathwy is a matter of discussion. Other herbal therapies are considered to affect the rennin-angiotensisn-aldosterone (RAA) system Ephedra sinica Stapf with its ingredient ephedrine. Devil's Claw (Harpagophytum procumbens DC. Ex Meisn.) and licorice (Glycyrrhiza glabra L.) may inhibit major renal transport processes needed for filtration, secretion, and absorption. Strategies to minimize nephrotoxicity include (1) quality control and standardization of herbal products, (2) research on the molecular modes of action to better understand pathophysiological mechanisms of herbal products as well as (3) clinical trials to demonstrate efficacy and safety.

    Joo, CH, Hwang-Bo, K, and Jee, H. Technical and physical activities of small-sided games in young Korean soccer players. J Strength Cond Res 30(8): 2164-2173, 2016-The aim of this study was to examine the technical aspects and physical demands during small-sided games (SSGs) with different sized pitches in young Korean soccer players. Participants were randomly selected during a nationally held youth competition. Three different game formats were used: SSG8 (8 vs. 8 played on a small-sized field [68 × 47 m]), RSG8 (8 vs. 8 played on a regular-sized field [75 × 47 m]), and RSG11 (11 vs. 11 played on a regular-sized field). Eleven technical (ball touches, passes, and shots) and 6 physical demand variables (exercise frequency by intensity) were observed and analyzed. Same variables were also analyzed for the goalkeepers. As a result, SSG8 and RSG8 showed significantly greater numbers of technical plays in 5 and 4 variables in comparison to RSG11, respectively. In addition, although the exercise intensities increased slightly in both SSG formats, the amount was within the similar range as previous reports. In conclusion, the SSGs with reduced number of players may be referred in young players to effectively train them in technical aspects of the game by allowing greater ball exposure time without excessive physical demands. Various confounding factors such as pitch dimension should be carefully considered for training specific technical and physical variables in young Korean players.

Although many studies have addressed the relationship between the vitamin D receptor (VDR polymorphisms and bone health, this relationship has not been fully investigated in patients with COPD. In this study, we investigated the association of VDR polymorphisms with bone mineral density (BMD and other clinical parameters in patients with COPD. Patients and methods: In total, 200 patients with COPD were included in this study. The VDR polymorphisms rs1544410 (A/G-BsmI, rs7975232 (A/C-ApaI, rs731236 (C/T-TaqI, and rs10735810 (C/T-FokI were determined by Sanger sequencing using blood DNA samples. BMD of the lumbar vertebra and the femoral neck was measured by dual-energy X-ray absorptiometry. Other clinical parameters were also evaluated. Haplotype and multivariate analyses were also performed. Results: Sex, body mass index, steroid use, percentage of forced expiratory volume in 1 second (FEV1, alkaline phosphatase, and 25-hydroxyvitamin D significantly influenced the risk of osteoporosis. Patients with osteoporosis were more likely to carry the rs7975232 C allele compared to normal patients with BMD. Haplotypes GCT and GAT were related to osteoporosis. Patients without the haplotype GAT allele showed a significantly lower T-score at the femoral neck and an increased risk of osteoporosis (odds ratio [OR]= 2.78, 95% confidence interval [CI]= 1.20–6.48, P=0.018 compared with carriers in the dominant model. Conclusion: Genetic variations in VDR are significantly associated with osteoporosis among patients with COPD

Cancer-associated fibroblasts can promote the proliferation of colon cancer cells and growth of colon cancer tumors. Methods: We examined the role of cathelicidin in the development of colon cancer, using subcutaneous human HT-29 colon-cancer-cell-derived tumor model in nude mice and azoxymethane- and dextran sulfate-mediated colon cancer model in C57BL/6 mice. We also determined the indirect antitumoral mechanism of cathelicidin via the inhibition of epithelial–mesenchymal transition (EMT of colon cancer cells and fibroblast-supported colon cancer cell proliferation. Results: Intravenous administration of cathelicidin expressing adeno-associated virus significantly reduced the size of tumors, tumor-derived collagen expression, and tumor-derived fibroblast expression in HT-29-derived subcutaneous tumors in nude mice. Enema administration of the mouse cathelicidin peptide significantly reduced the size and number of colonic tumors in azoxymethane- and dextran sulfate-treated mice without inducing apoptosis in tumors and the adjacent normal colonic tissues. Cathelicidin inhibited the collagen expression and vimentin-positive fibroblast expression in colonic tumors. Cathelicidin did not directly affect HT-29 cell viability, but did significantly reduce tumor growth factor-ß1-induced EMT of colon cancer cells. Media conditioned by the

Accomplishing this kind of strategy requires a specific drug-delivery system using the distinct features of liposomes. Studies on targeted liposomal delivery systems have indicated the conjugation of hyaluronan (HA, a primary ligand for CD44 surface markers, as an appropriate method for targeting BCSCs. For this study, enriched BCSCs were obtained by culturing MCF-7 breast cancer cells in nonadherent conditions. The enriched BCSCs were challenged with HA-conjugated liposomes encapsulating gemcitabine (2, 2-difluoro-2-deoxycytidine, GEM. In vitro study showed that the HA-conjugated liposomes significantly enhanced the cytotoxicity, anti-migration, and anti-colony formation abilities of GEM through targeting of CD44 expressed on BCSCs. In pharmacokinetic study, area under the drug concentration vs time curve (AUC of the immunoliposomal GEM was 3.5 times higher than that of free GEM, indicating that the HA-conjugated liposomes enhanced the stability of GEM in the bloodstream and therefore prolonged its half-life time. The antitumor effect of the immunoliposomal GEM was 3.3 times higher than that of free GEM in a xenograft mouse model, probably reflecting the unique targeting of the CD44 receptor by HA and the increased cytotoxicity and stability through the liposomal formulation. Furthermore, marginal change in body weight demonstrated that the use of liposomes considerably reduced the systemic toxicity of GEM on normal healthy cells. Taken together

    Full Text Available Ehabla is one of oral poetry in Sentani, Papua that is almost extinct. It is sung spontaneously, without background of notes and memorization. The singer prepares plot and theme that will be elaborated in the performance, Ehabla can be transcribed into 4 lines that is dominated by repetition and parallelism. The first line is repeated in the third line, the second line is repeated in the fourth line. Essentially, the third and the fourth lines are the repetition of the first and the second lines. The repetition is enriched by synonym and reduplication. Ehabla that expresses the socio-cultural life of Sentani people can be used as media of (1 education (pedagogical system that teaches hard work, cooperation, pride, respecting tradition, proud of birthplace, respecting natural environment; (2 reflection of Sentani people's idealization on ideal village, ideal society, and ideal leaders; (3 legitimacy of traditions; (4 forcing and watching; (5 sharpening the emotion of religion and belief; and (6 entertainment. For Sentani people who live in some remote areas in some islands, the singing and function of ehabla are still responded even though its socialization is not positively responded by the young generation. For Sentani people who live near the city, the singing and function of ehabla are not again responded by both old and young generation. This is caused by the influence of new traditions, technology, and globalization. The only function that is still alive is the function of entertainment.

    Language deficits in people with Alzheimer's disease (AD) manifest, among other things, in a gradual deterioration of spontaneous speech. People with AD tend to speak less as the disease progresses and their speech becomes confused. However, the ability to sing old tunes sometimes remains intact throughout the disease. The purpose of this study was to explore the role of singing familiar songs in encouraging conversation among people with middle to late stage AD. Six participants attended group music therapy sessions over a one-month period. Using content analysis, we qualitatively examined transcriptions of verbal and sung content during 8 group sessions for the purpose of understanding the relationship between specific songs and conversations that occurred during and following group singing. Content analysis revealed that songs from the participants' past-elicited memories, especially songs related to their social and national identity. Analyses also indicated that conversation related to the singing was extensive and the act of group singing encouraged spontaneous responses. After singing, group members expressed positive feelings, a sense of accomplishment, and belonging. Carefully selecting music from the participants' past can encourage conversation. Considering the failure in spontaneous speech in people with middle to late stage AD, it is important to emphasize that group members' responses to each other occurred spontaneously without the researcher's encouragement. © the American Music Therapy Association 2014.

    The purpose of the present study was to investigate vocal singing performance of hearing-impaired children with cochlear implants (CI) and hearing aids (HA) as well as to evaluate the relationship between demographic factors of those hearing-impaired children and their singing ability. Thirty-seven prelingually-deafened children with CIs and 31 prelingually-deafened children with HAs, and 37 normal-hearing (NH) children participated in the study. The fundamental frequencies (F0) of each note in the recorded songs were extracted and the duration of each sung note was measured. Five metrics were used to evaluate the pitch-related and rhythm-based aspects of singing accuracy. Children with CIs and HAs showed significantly poorer performance in either the pitch-based assessments or the rhythm-based measure than the NH children. No significant differences were seen between the CI and HA groups in all of these measures except for the mean deviation of the pitch intervals. For both hearing-impaired groups, length of device use was significantly correlated with singing accuracy. There is a marked deficit in vocal singing ability either in pitch or rhythm accuracy in a majority of prelingually-deafened children who have received CIs or fitted with HAs. Although an increased length of device use might facilitate singing performance to some extent, the chance for the hearing-impaired children fitted with either HAs or CIs to reach high proficiency in singing is quite slim.
