Assessing a Collaborative Online Environment for Music Composition

The current pilot study tested the effectiveness of an e-learning environment built to enable students to compose music collaboratively. The participants interacted online by using synchronous and asynchronous resources to develop a project in which they composed a new music piece in collaboration. After the learning sessions, individual semi-structured interviews with the participants were conducted to analyze the participants\u2019 perspectives regarding the e-learning environment\u2019s functionality, the resources of the e-learning platform, and their overall experience with the e-learning process. Qualitative analyses of forum discussions with respect to metacognitive dimensions, and semi-structured interview transcriptions were performed. The findings showed that the participants successfully completed the composition task in the virtual environment, and that they demonstrated the use of metacognitive processes. Moreover, four themes were apparent in the semi-structured interview transcriptions: Teamwork, the platform, face-to-face/online differences, and strengths/weaknesses. Overall, the participants exhibited an awareness of the potential of the online tools, and the task performed. The results are discussed in consideration of metacognitive processes, and the following aspects that rendered virtual activity effective for learning: The learning environment, the platform, the technological resources, the level of challenge, and the nature of the activity. The possible implications of the findings for research on online collaborative composition are also considered

A validity and reliability study of the Attitudes toward Sustainable Development scale

This article describes the development and validation of the Attitudes toward Sustainable Development scale, a quantitative 20-item scale that measures Italian university students\u2019 attitudes toward sustainable development. A total of 484 undergraduate students completed the questionnaire. The validity and reliability of the scale was statistically tested by computing the KMO and Bartlett tests and via an exploratory factor analysis, descriptive statistics, Cronbach\u2019s alpha, a confirmatory factor analysis and a multi-group invariance testing. The results of the principal components factor analysis show that the scale consists of the following four dimensions, with five items in each: environment, economy, society and education. The overall structure and measurement of the scale are confirmed by the confirmatory factor analysis and by the multi-group invariance testing. Internal reliability, which was found using Cronbach\u2019s alpha, varies between .660 and .854. The results show that the instrument meets the validity and reliability criteria. To demonstrate its utility, the scale was applied to detect differences in sustainable development attitudes among students pursuing degrees in psychology and in agriculture. Relevant differences were detected for the dimensions of environment and society. The Attitudes toward Sustainable Development scale could be useful for understanding the ways in which students think about sustainability issues and could be used to investigate the relationship between sustainability attitudes and other variables

Assessing the infusion of sustainability principles into university curricula

open3siThe current paper presents the assessment of the infusion of sustainability principles into university curricula at two Jordanian universities. The peer review process of revising the curricula infusing sustainability principles is also discussed. The research methodology involved quantitative methods to assess the revised courses. The results revealed the following: the most relevant ESD themes in the revised curricula were ìhuman connections to the physical and natural worldî, and ìethics/valuesî. The most relevant ESD topics were: ìsustainable production/consumptionî and ìhealth promotionî. The most infused ESD pillars (competencies) were: ìlearning to knowî and ìlearning to doî. The most relevant ESD principles were: ìpracticed locallyî and ìresponds through applied learningî. The findings offered a rich scenario of the strategies applied by the university professors in revising the curricula, providing evidence of a mental attitude to adopt ESD strategies, as well as a goal-oriented approach in curriculum planning. The paper also discusses the implications of the study results for syllabus revision and development, as well as the refinement of the teaching methods that focus on infusing sustainability into university curricula.

Music regulators in two string quartets: A comparison of communicative behaviors between low- and high-stress performance conditions

In ensemble performances, group members use particular bodily behaviors as a sort of “language” to supplement the lack of verbal communication. This article focuses on music regulators, which are defined as signs to other group members for coordinating performance. The following two music regulators are considered: body gestures for articulating attacks (a set of movements externally directed that are used to signal entrances in performance) and eye contact. These regulators are recurring observable behaviors that play an important role in non-verbal communication among ensemble members. To understand how they are used by chamber musicians, video recordings of two string quartet performances (Quartet A performing Bartók and Quartet B performing Haydn) were analyzed under two conditions: a low stress performance (LSP), undertaken in a rehearsal setting, and a high stress performance (HSP) during a public recital. The results provide evidence for more emphasis in gestures for articulating attacks (i.e., the perceived strength of a performed attack-type body gesture) during HSP than LSP. Conversely, no significant differences were found for the frequency of eye contact between HSP and LSP. Moreover, there was variability in eye contact during HSP and LSP, showing that these behaviors are less standardized and may change according to idiosyncratic performance conditions. Educational implications are discussed for improving interpersonal communication skills during ensemble performance

Effects of Music Therapy on Drug Therapy of Adult Psychiatric Outpatients: A Pilot Randomized Controlled Study

Objective: Framed in the patients\u2019 engagement perspective, the current study aims to determine the effects of group music therapy in addition to drug care in comparison with drug care in addition to other non-expressive group activities in the treatment of psychiatric outpatients. Method: Participants (n D 27) with ICD-10 diagnoses of F20 (schizophrenia), F25 (schizoaffective disorders), F31 (bipolar affective disorder), F32 (depressive episode), and F60 (specific personality disorders) were randomized to receive group music therapy plus standard care (48 weekly sessions of 2 h) or standard care only. The clinical measures included dosages of neuroleptics, benzodiazepines, mood stabilizers, and antidepressants. Results: The participants who received group music therapy demonstrated greater improvement in drug dosage with respect to neuroleptics than those who did not receive group music therapy. Antidepressants had an increment for both groups that was significant only for the control group. Benzodiazepines and mood stabilizers did not show any significant change in either group. Conclusion: Group music therapy combined with standard drug care was effective for controlling neuroleptic drug dosages in adult psychiatric outpatients who received group music therapy. We discussed the likely applications of group music therapy in psychiatry and the possible contribution of music therapy in improving the psychopathological condition of adult outpatients. In addition, the implications for the patient-centered perspective were also discussed

Riboflavin-sensitized photooxidation of Ceftriaxone and Cefotaxime: kinetic study and effect on Staphylococcus aureus

Trace amounts of the widely used β-lactam antibiotics (Atbs) in waste water may cause adverse effects on the ecosystems and contribute to the proliferation of antibiotic-resistant bacteria. On these grounds, kinetic and mechanistic aspects of photosensitized degradation of Ceftriaxone (Cft) and Cefotaxime (Ctx), have been studied in pure water by stationary and time-resolved techniques. Additionally, possible implications of these photoprocesses on the antimicrobial activity of the Atbs have also been investigated. Photoirradiation of aqueous solutions of Cft and Ctx produces the degradation of both Atbs in the presence of Riboflavin (vitamin B2), a well known pigment dissolved in natural aquatic systems. The process occurs through Type I and Type II mechanisms, with effective prevalence of the former. The participation of O2−, OH and O2(1Δg) is supported by experiments of oxygen consumption carried out in the presence of specific scavengers for such reactive oxygen species. Microbiological assays exhibit a parallelism between the rate of Cft and Ctx photodegradation and the loss of their bactericidal capacity on Staphylococcus aureus strains. Results contribute to both understanding kinetic and mechanism aspects of the degradation and predicting on natural decay of Atbs waste water-contaminants.Fil: Reynoso, Eugenia.

Predicción del rendimiento de híbridos de maíz (Zea mays L.) en ambientes de siembra tardía

La predicción precisa del comportamiento de híbridos de maíz no evaluados a campo permitirá un mayor progreso genético y menores costos en programas de mejoramiento genético. Datos de rendimiento de híbridos evaluados a campo se emplearon para predecir el comportamiento de nuevos híbridos en ambientes de siembra tardía. Se conformaron grupos de híbridos predictores de manera de maximizar y minimizar las relaciones de parentesco entre los híbridos predictores y aquellos a predecir y, por otra parte, utilizar valores de predicción obtenidos en ambientes de alto rendimiento y bajo rendimiento a fin de investigar la influencia de estos factores sobre la eficiencia de las predicciones. A fin de validar las predicciones se tomó un grupo de híbridos cuyo rendimiento en grano fue evaluado a campo, pero que no formaron parte del grupo inicial. Se calcularon los coeficientes de correlación entre los valores predichos y los observados para rendimiento con el fin de evaluar la efectividad de la predicción realizada. La mejor predicción de los híbridos no evaluados, se alcanzó utilizando la máxima relación de parentesco entre los híbridos combinada con datos obtenidos en el ambiente de mayor rendimiento promedio.Accurate prediction of the phenotypical performance of untested single-cross hybrids allows for a faster genetic progress of the breeding pool at a reduced cost. Yield data of maize hybrids were employed to predict the performance of new untested hybrids in late sowing environments. Different groups of predictor hybrids were formed using both data from high and low relatedness between predictors and predicted hybrids and by employing data from low and high yielding environments. A new group of hybrids were formed and evaluated in field trials to validate the predictions. The effectiveness of the predictions was investigated by means of the correlation coefficient between predicted and observed yield values. The best predictions of untested new hybrids were reached by using maximum relatedness information combined with data obtained in the best yielding environments.Fil: Biasutti, Carlos Alberto.
