Varieties of Musicological Empiricism

Empiricism should not be seen to provide an overarching criterion of meaningfulness for musicological concepts nor a single comprehensive methodology for music research. Understood as methodological concern with observation (perception, experience, etc.), it is rather a possible orientation that may receive various degrees of emphasis. Empiricism is not opposed to theoretical systematization, but it can rather be seen as an inclination towards theories which are capable of empirical adequacy. The empirical, or observational component of research may nevertheless be understood in slightly different ways, depending on whether there is only one observer (or many), and depending on whether the observations are treated as falling within a single category (or not). It is argued that either the observer or the observational category has to be assumed constant in order that the research may be called truly empirical. It is also argued that such decisions concerning empirical methodology naturally correspond to distinctions between subdisciplines of empirical musicology, each of them associated with different research interests. Three such orientations are discussed: historico-analytical empiricism, psychological empiricism, and systematic empiricism

Early attraction in temporally controlled sight reading of music

A music reader has to “look ahead” from the notes currently being played—this has usually been called the Eye-Hand Span. Given the restrictions on processing time due to tempo and meter, the Early Attraction Hypothesis suggests that sight readers are likely to locally increase the span of looking ahead in the face of complex upcoming symbols (or symbol relationships). We argue that such stimulus-driven effects on looking ahead are best studied using a measure of Eye-Time Span (ETS) which redefines looking ahead as the metrical distance between the position of a fixation in the score and another position that corresponds to the point of metrical time at fixation onset. In two experiments of temporally controlled sight reading, musicians read simple stepwise melodies that were interspersed with larger intervallic skips, supposed to create points of higher melodic complexity (and visual salience) at the notes following the skips. The results support both Early Attraction (lengthening of looking ahead) and Distant Attraction (lengthening of incoming saccades) in the face of relative melodic complexity. Notably, such effects also occurred on the notes preceding the nominally complex ones. The results suggest that saccadic control in music reading depends on temporal restrictions as well as on local variations in stimulus complexity

Successful approaches to mental practice: A case study of four pianists

Musicians often use mental practice for enhancing performance, but individuals may have different preferences and skills in their characteristic, individually successful ways of carrying out such practice. In this study, we focus on the approaches to mental practice of four pianists who, according to the ratings of a panel of expert judges, showed outstanding improvement in their performances following their mental practice of a new piece in at least one of the two conditions: silent reading of the score or reading the score while simultaneously listening to the music. The four pianists’ approaches to mental practice were studied through self-reports in post-task interviews that were compared with eye-tracking data gathered during the actual mental practice. In successful mental practice, the pianists relied on their experience and the skills they had practised in audiation, use of recordings, imaginary rehearsal, and structural analysis. The results encourage musicians to explore their characteristic approaches to mental practice, and to deliberately practise and develop versatile mental practice skills in order to apply them flexibly in different musical situations. Eye tracking was found to be a useful tool for validating and supplementing musicians’ subjective self-descriptions and for revealing covert mental processes in the context of music reading.</p

Verktygsrelaterad flexibilitet som undervisningskompetens

In the current debate concerning the Swedish Schools of Music and Performing Arts (SMPAs) the concept of flexibility is frequently used. Here it mostly describes the necessity to take students’ requests and needs into account in teacher education and the institutions’ ability to adapt to changing demands for artistic activities among children and adolescents. In contrast to this view, this study examines flexibility as a central competency of the teaching profession and particularly in a curriculum-free environment such as the SMPAs. Resting on the assumption that teachers with a large toolkit have a certain advantage in practising flexibility, the study is based on interviews with three multi-instrumentalists, all of them experienced music teachers in SMPAs. The analysis suggests three forms of flexibility that are related to the teachers’ use of instrumental tools, each of them emerging in particular kinds of teaching activities: problem-solving flexibility in instrument-related counseling, method flexibility in ensemble leadership, and role flexibility in group music-making. The findings are discussed in relation to ideals of teacher specialization and versatility, and the notion of tool-based flexibility is distinguished from improvisation as a teaching skill.

Antimicrobial characterization of silver nanoparticle-coated surfaces by “touch test” method

Abstract: Bacterial infections, especially by antimicrobial resistant (AMR) bacteria, are an increasing problem worldwide. AMR is especially a problem with health care-associated infections due to bacteria in hospital environments being easily transferred from patient to patient and from patient to environment, and thus, solutions to prevent bacterial transmission are needed. Hand washing is an effective tool for preventing bacterial infections, but other approaches such as nanoparticle-coated surfaces are also needed. In the current study, direct and indirect liquid flame spray (LFS) method was used to produce silver nanoparticle-coated surfaces. The antimicrobial properties of these nanoparticle surfaces were evaluated with the “touch test” method against Escherichia coli and Staphylococcus aureus. It was shown in this study that in glass samples one silver nanoparticle-coating cycle can inhibit E. coli growth, whereas at least two coating cycles were needed to inhibit S. aureus growth. Silver nanoparticle-coated polyethylene (PE) and PE terephthalate samples did not inhibit bacterial growth as effectively as glass samples: three nanoparticle-coating cycles were needed to inhibit E. coli growth, and more than 30 coating cycles were needed until S. aureus growth was inhibited. To conclude, with the LFS method, it is possible to produce nanostructured large-area antibacterial surfaces which show antibacterial effect against clinically relevant pathogens. Results indicate that the use of silver nanoparticle surfaces in hospital environments could prevent health care-associated infections in vivo.</p

Hand washing with soap and water together with behavioural recommendations prevents infections in common work environment: an open cluster-randomized trial

<p>Abstract</p> <p>Background</p> <p>Hand hygiene is considered as an important means of infection control. We explored whether guided hand hygiene together with transmission-limiting behaviour reduces infection episodes and lost days of work in a common work environment in an open cluster-randomized 3-arm intervention trial.</p> <p>Methods</p> <p>A total of 21 clusters (683 persons) were randomized to implement hand hygiene with soap and water (257 persons), with alcohol-based hand rub (202 persons), or to serve as a control (224 persons). Participants in both intervention arms also received standardized instructions on how to limit the transmission of infections. The intervention period (16 months) included the emergence of the 2009 influenza pandemic and the subsequent national hand hygiene campaign influencing also the control arm.</p> <p>Results</p> <p>In the total follow-up period there was a 6.7% reduction of infection episodes in the soap-and water arm (p = 0.04). Before the onset of the anti-pandemic campaign, a statistically significant (p = 0.002) difference in the mean occurrence of infection episodes was observed between the control (6.0 per year) and the soap-and-water arm (5.0 per year) but not between the control and the alcohol-rub arm (5.6 per year). Neither intervention had a decreasing effect on absence from work.</p> <p>Conclusions</p> <p>We conclude that intensified hand hygiene using water and soap together with behavioural recommendations can reduce the occurrence of self-reported acute illnesses in common work environment. Surprisingly, the occurrence of reported sick leaves also increased in the soap-and water-arm.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov: <a href="http://www.clinicaltrials.gov/ct2/show/NCT00981877">NCT00981877</a></p> <p>Source of funding</p> <p>The Finnish Work Environment Fund and the National Institute for Health and Welfare.</p
