Factors affecting performance proficiency : a case study involving intermediate piano students

The goal of this study was to determine the effect of a number of factors on the performance proficiency of three intermediate piano students having different learning styles, all of whom shared the same teacher. Four sets of data were collected in this investigation: the methodology of the teacher; the practice behaviour of the participants; the effect of intrinsic factors, such as participant attitude, motivation, and ownership of learning; and the effect of extrinsic factors that included parental influence, and participants' school- and employment-related responsibilities. Performance proficiency and assessment of practice behaviour were measured by three external, professionallyqualified music examiners. Performance proficiency varied to some extent between participants, but they shared similar practice behaviours. Learning style does not, therefore, affect practice behaviour. Although they planned their practice time, participants did not show much evidence of monitoring the quality of their practice. On the other hand, participants showed positive attitude; they were motivated to learn; and they were observed to plan their practice time, all indicators of, among other things, positive influence of the teacher and parents. Participants showed evidence that these constructive habits were a denominator common to both their schoolwork and piano practice. It was apparent that, except for learning style, all factors examined had an effect on performance proficiency. Performance proficiency is, therefore, influenced by a large web of factors, a finding that is instructive for classroom teachers. Teachers need to avoid the temptation to teach toward performance expectations. Emphasis should be placed instead on teaching and assessing formative learning strategies.

Virginia Apgar and string music

Virginia Apgar (1909-1974) is one of the most recognized American doctors, worldwide known by his contribution as the developer of the "Apgar test" a method used for the evaluation of newborns all over the world. She had many interests. She was anesthesiologist, a brilliant teacher and researcher, but she also loved lecture, basketball, fishing, golf, philately, and music. She played violin and cello and she interpreted that instruments in various chamber groups. Being motivated by one of her patients, Carleen Hutchinson, a science and music teacher, she made four instruments, viola, violin, cello, and mezzo violin. Nearly twenty years of her death, on October 24 1994, on the occasion of the annual meeting of the American Academy of Pediatrics and the issue by American Postal Service of a stamp honoring her, some of the preferred Dr. Apgar music pieces where performed with the instruments she made. Her life mixed different activities and let invaluable contributions for humanity.

Assessment of the Ability to Relate Anterior Tooth Form and Arrangement to Gender

Purpose: This study evaluated the assumption that there are morphological differences between the natural anterior dentition of men and women. The goal of the study was to determine the gender of patients based on the appearance of the anterior teeth in photographs. Materials and Methods: Laymen and observers from different specialties were asked to determine the gender of individuals based on the shape and arrangement of anterior teeth. Forty anterior dentition photographs of dental students of both genders (20 women, 20 men) between 18 and 26 years old were selected, coded, and randomly arranged in an album. The albums were delivered to five groups of observers: general practitioners (recently graduated dentists), prosthodontists, orthodontists, restorative dentists (specialists in cosmetic and restorative dentistry), and laymen (control group). The observers evaluated the photographs twice at 1-week intervals. Results: The average correctly identified values in women and men were 57.6% and 58.8%, respectively. There was no statistical difference between observers and between each group of professionals and the laymen group (p > 0.05). An intraobserver agreement was not observed between the evaluations (kappa =-0.01). Conclusion: The results of this limited study indicated that it was not possible to differentiate gender by viewing photographs of anterior teeth.

Accumulation of dry mass and macronutrients by sourgrass plants

The experiment was carried out aiming to analyze the dry mass production and distribution and the content and accumulation of macronutrients in sourgrass (Digitaria insularis) plants cultivated under mineral nutrition standard conditions. Plants grew in 7-liter pots filled with sand substrate and daily irrigated with nutrient solution, being maintained under greenhouse conditions. Treatments consisted of times of evaluation (21, 35, 49, 63, 77, 91, 105, 119, and 133 days after emergence - DAE) and were arranged in a completely randomized design with four replicates. Sourgrass showed small accumulation of dry mass (0.3 g per plant) and macronutrients (3.7 mg of N per plant, 0.4 mg of P per plant, 5.6 mg of K per plant, 0.9 mg of Ca per plant, 0.7 mg of Mg per plant, and 0.3 mg of S per plant) at vegetative growth stage (< 49 DAE). Those accumulations increased mainly after 77 DAE, reaching the maximum theoretical value at 143, 135, 141, 129, 125, 120, and 128 DAE, for dry mass (12.4 g per plant), N (163.2 mg per plant), P (27.1 mg per plant), K (260.5 mg per plant), Ca (47.6 mg per plant), Mg (30.9 mg per plant), and S (13.7 mg per plant), respectively. K and N were found with higher rates and, as a consequence, they were required and accumulated in greater amounts in plant tissues of sourgrass.

Investigation of the relationship between the structure and function of Ts2, a neurotoxin from Tityus serrulatus venom

Scorpion toxins targeting voltage-gated sodium (NaV) channels are peptides that comprise 6076 amino acid residues cross-linked by four disulfide bridges. These toxins can be divided in two groups (a and beta toxins), according to their binding properties and mode of action. The scorpion a-toxin Ts2, previously described as a beta-toxin, was purified from the venom of Tityus serrulatus, the most dangerous Brazilian scorpion. In this study, seven mammalian NaV channel isoforms (rNaV1.2, rNaV1.3, rNaV1.4, hNaV1.5, mNaV1.6, rNaV1.7 and rNaV1.8) and one insect NaV channel isoform (DmNaV1) were used to investigate the subtype specificity and selectivity of Ts2. The electrophysiology assays showed that Ts2 inhibits rapid inactivation of NaV1.2, NaV1.3, NaV1.5, NaV1.6 and NaV1.7, but does not affect NaV1.4, NaV1.8 or DmNaV1. Interestingly, Ts2 significantly shifts the voltage dependence of activation of NaV1.3 channels. The 3D structure of this toxin was modeled based on the high sequence identity (72%) shared with Ts1, another T. serrulatus toxin. The overall fold of the Ts2 model consists of three beta-strands and one a-helix, and is arranged in a triangular shape forming a cysteine-stabilized a-helix/beta-sheet (CSa beta) motif.

Mineral and chemical composititon of sediments from ODP Hole 119-740A

ODP Hole 740A is located on the inner part of the East Antarctic continental shelf in Prydz Bay, at the seaward end of a major onshore rift structure known as the Lambert Graben. Drilling at this site led to the recovery of some 65 m of continental sediments (Prydz Bay red beds) that form part of a much thicker (2-3 km) pre-continental breakup sequence, the development of which may be related to the initiation and rifting of the Lambert Graben. Palynological and paleomagnetic studies have not been able to determine the age of the sediments; they may be equivalent to the onshore late Permian Amery Group or younger. The succession consists predominantly of sandstone, siltstone, and claystone arranged in erosively based, pedogenically influenced fining-upward sequences up to 5 m thick. These were deposited by shallow, braided streams draining an extensively vegetated alluvial plain, with sufficient topographic relief to trap fine-grained sediment and inhibit rapid channel shifting. Pedogenic processes were initiated on the alluvial plain, but climatic conditions were generally unsuitable for extensive pedogenic carbonate formation and the development of mature soil profiles. The sediments were probably derived from a rapidly uplifted fault block terrain composed of upper Proterozoic and Archaean gneisses lying to the southeast of the depositional site. Uplift may have taken place along the tectonically active seaward extension of the eastern faulted margin of the Lambert Graben, which passes immediately southeast of Hole 740A. Differences in mineralogical composition between the Amery Group and the Prydz Bay red beds probably reflect differences in rock composition in the source area. The age of the Prydz Bay red beds has still to be resolved.
