    The kinetics and acoustics of fingering and note transitions on the flute

    Full text link
    Motion of the keys was measured in a transverse flute while beginner, amateur and professional flutists played a range of exercises. The time taken for a key to open or close is typically 10 ms when pushed by a finger or 16 ms when moved by a spring. Delays between the motion of the fingers were typically tens of ms, with longer delays as more fingers are involved. Because the opening and closing of keys will never be exactly simultaneous, transitions between notes that involve the movement of multiple fingers can occur via several possible pathways with different intermediate fingerings. A transition is classified as `safe' if it is possible to be slurred from the initial to final note with little perceptible change in pitch or volume. Some transitions are `unsafe' and possibly involve a transient change in pitch or a decrease in volume. In transitions with multiple fingers, players, on average, used safe transitions more frequently than unsafe transitions. Professionals exhibited smaller average delays between the motion of fingers than did amateurs

    The study was conducted to ascertain the effect of ethno-mathematics teaching materials on students’ achievement in mathematics. The sample for the study was 156 Senior Secondary Schools two (SSS 2) students, which were randomly selected from 16 Senior Secondary Schools in Igbo-Etiti Local Government Area of Enugu State through multi-stage sampling technique. The instrument used for the study was ethno-mathematics achievement test (ETHNOMAT). The data obtained with the instrument were analyzed using mean and Analysis of covariance (ANCOVA). Mean was used to answer the research questions posed, while ANCOVA statistic was employed in testing the null hypothesis at 0.05 significant level. Findings of the study showed that the ethno-mathematic achievement test was effective in enhancing students’ achievement in mensuration with particular reference to volumes of cylinder and hemisphere. It was recommended among others that ethno-mathematics teaching materials should be incorporated in the Senior Secondary School mathematics curriculum as technique to be used by teachers in teaching the concepts of volumes of cylinders and hemispheres. More so, workshops/Seminars should be organized by professional bodies such as Science Teachers Association of Nigeria (STAN), Mathematical Association of Nigeria (MAN), among other bodies, to popularize and sensitize mathematics teachers on the use of ethno-mathematics teaching materials as approach in teaching students the concepts of volumes of cylinders and hemispheres. Keywords: Ethno-Mathematics, Native Calabash Cups, Native Calabash Plates, Volume of Cylinder, and Volume of Hemispher

    Salary determination in the National Hockey League: The development of an equitable player compensation model.

    Nowhere else in North America is the performance of an employee so readily visible and so easily measured than in the sport of professional ice hockey (Banister, 1997). Although the performance of professional athletes may be objectively measured and compared by the vast quantities of statistics compiled by sports analysts, controversy still surrounds whether their individual efforts justify their salaries (Banister, 1997, p. 47). NHL salaries have become so disparate in recent years that it is quite common for certain \u27marquee\u27 players to earn 10--20 times the salary of other players competing on the same team (Banister, 1997). With 50% of the salary money being claimed by the top 10% of players (Hale, 1994), one must question the effectiveness of the current NHL compensation system in terms of its ability to distribute players\u27 earnings in an objective and equitable manner. This study utilized a modified Delphi methodology to elicit participation from a panel of 16 hockey experts in as to what variables should be important in determining the salary of a NHL forward. Based on these results, the researcher proposed a compensation model that is predicated upon the theoretical underpinnings of Employee Equity. The implementation of an objective and equitable means of determining a player\u27s economic livelihood may have considerable implications for improved labour relations, cost-containment, competitive parity, and resultantly, fan support in the National Hockey League.Dept. of Kinesiology.

    This study investigated the influence of professional status and condition of service on teacher productivity in primary schools in Zuru Emirate of Kebbi State. A correlational survey design was adopted for the study. Stratified, proportionate and simple random sampling techniques were used to select 346 teachers out of 3,687. Questionnaire and Teacher Productivity Evaluation Format were used as instruments for data collection. The five-point scale instruments were validated by experts and pilot tested and had reliability indexes of 0.83 and 0.85 respectively, using Cronbach Alpha co-efficient. Findings of the study showed that the level of teacher productivity was rated low; professional status and conditions of service were both rated poor. This unfavourable situation has negatively influenced teacher productivity. It was recommended that strategies be put in place to improve teachers’ productivity in terms of quality of teaching, record keeping and other activities. The status of teaching should be upgraded and primary school teachers to be provided with better conditions of service to enhance their productivit

    Identifying the machine translation error types with the greatest impact on post-editing effort

    Translation Environment Tools make translators' work easier by providing them with term lists, translation memories and machine translation output. Ideally, such tools automatically predict whether it is more effortful to post-edit than to translate from scratch, and determine whether or not to provide translators with machine translation output. Current machine translation quality estimation systems heavily rely on automatic metrics, even though they do not accurately capture actual post-editing effort. In addition, these systems do not take translator experience into account, even though novices' translation processes are different from those of professional translators. In this paper, we report on the impact of machine translation errors on various types of post-editing effort indicators, for professional translators as well as student translators. We compare the impact of MT quality on a product effort indicator (HTER) with that on various process effort indicators. The translation and post-editing process of student translators and professional translators was logged with a combination of keystroke logging and eye-tracking, and the MT output was analyzed with a fine-grained translation quality assessment approach. We find that most post-editing effort indicators (product as well as process) are influenced by machine translation quality, but that different error types affect different post-editing effort indicators, confirming that a more fine-grained MT quality analysis is needed to correctly estimate actual post-editing effort. Coherence, meaning shifts, and structural issues are shown to be good indicators of post-editing effort. The additional impact of experience on these interactions between MT quality and post-editing effort is smaller than expected

    Teachers' Burnout Profile- Risk and protective factors

    Get PDF
    Background: Burnout syndrome represents a factual risk for school teachers during their career. Several factors have been analyzed as stress sources enabled to menace teachers’ general well-being; nevertheless, protective factors mostly related to their personal resources may differently characterize teachers’ profiles. Objectives: The current study aimed to define different teachers’ profiles based on their burnout levels and attitudes towards job (i.e., job satisfaction, self-efficacy, attitudes toward professional growth, collective efficacy, positive and negative emotions, and hedonic balance). attitudes towards job Methods: Participants were 266 school teachers (F=69.1%) ranging from 26 to 65 years old (M=48.95; SD=8.31), with teaching experience ranged from 1 to 41 years (M=21.72; SD=10.36). Data were collected by three self-report questionnaires: Copenhagen Burnout Inventory, Attitudes towards job questionnaires, School Collective efficacy. Results: Cluster analysis approach showed two distinct teacher’s profiles named at-risk and non at-risk teachers. Main differences were due to burnout levels, attitudes toward job and extra-mansions at work. No differences were found related to teachers’ socio-demographic characteristics and their years of experience. Conclusions: The two teachers’ profiles resulting from the cluster analysis show several similarities, including collective efficacy and job satisfaction levels. Results are discussed in relation as to how teachers’ positive emotions towards their job can work as protective factors against the risk of burnou
