Can humming caregivers´ facilitate feeding during mealtime situations with persons with dementia? A qualitative study

Background. ‘Music Therapeutic Caregiving’, defined as when caregivers’ sing for or together with persons with dementia care situations, has been shown to facilitate the caring situation, and enhance positive and decrease negative expressions in persons with dementia. No studies about singing during mealtimes have been conducted, and this project was designed to elucidate this. However, since previous studies have shown that there is a risk that persons with dementia will start to sing along with the caregiver, the caregiver in this study hummed such that the person with dementia did not sing instead of eat. Aim. To describe professional caregivers’ experiences of humming during meal time while feeding persons with dementia. Method. An intervention with caregivers humming was implemented during lunch time. Focus group interviews were conducted to fetch the caregivers experiences. Qualitative content analysis was used to analyse the interviews. Results. The caregivers described that humming disseminated relaxation and joy, and awakened memories about the songs hummed which encouraged the persons with the dementia to join in the songs. They also described that humming seemed to make the persons with dementia associate with mealtime and could make them eat more. However it also revealed suspiciousness and agitation from the persons with dementia. Conclusion. Humming during mealtime revealed mainly positive as well as some negative influences. More and larger studies are needed to be able to draw general conclusions.

Cross cultural engagement: teaching African music to Australian students

This paper reports on research that examined the effectiveness of introducing rhythmic concepts through an unfamiliar musical genre to Australian generalist prim my teacher education students. The genre selected was African music, in particular action songs, dance and instrumental improvisation. The methodologies of Orff, Kodaly and Dalcroze were taught through the repertoire of African music in order to foster a closer relationship between pedagogical theory and practice and to teach rhythm through cross-cultural engagement. Through analyses of questionnaire and interview data, it was demonstrated that African music had a positive effect on students' conjidence as non-specialists music teachers and enhanced their skills in staff, sol-fa, hand notation and performance. Also students were not only highly motivated to engage with this new musical genre, but also gained an increased understanding of African culture. It is argued that African music was perceived by students not so much as a "novelty", but as a source of genuine motivation, interest and enjoyment. Its potential for extending student understanding of rhythm as well as taking a significant step towards internationalizing the curriculum for a cohort of predominantly Anglo-Celtic, pre-service teachers is also explored.

Forward gaily together : the school music compositions of Samuel McBurney

As one of the leading figures in nineteenth century school music in Victoria and more widely in Australia, Samuel McBurney contributed significantly to the promotion of Tonic Sol-fa as a music teaching method as well as to supporting the role of music as a subject in the school curriculum. However his role also extended to that of composer of vocal and choral works for both adults and children. Although largely conforming to the established genre of choral writing of his time, McBurney’s compositional output nevertheless represents a variety of styles ranging from lieder to school and popular songs, and from children’s cantatas to celebratory and patriotic anthems.

This paper considers a representative sample of McBurney’s compositional output in the light of both its musical and extra-musical content. It is argued that his compositions represent several important themes that emerged in Australian colonial society during the latter part of the nineteenth century. His music contributed not only to the moral and aesthetic development of school children but also supported the growing tide of nationalism (which resulted in Federation in 1901) in adult choral music making. Moreover, particularly in relation to his school cantatas, McBurney continued the tradition established by earlier school music composers in Australia - such as James Fisher in New South Wales - by providing a repertoire of choral music for use in schools which, to the present day with the current vogue for school musical productions, continues to be a source of enjoyment, celebration and 'healthful recreation' for young people.

Pollutants increase song complexity and the volume of the brain area HVC in a songbird

Environmental pollutants which alter endocrine function are now known to decrease vertebrate reproductive success. There is considerable evidence for endocrine disruption from aquatic ecosystems, but knowledge is lacking with regard to the interface between terrestrial and aquatic ecosystems. Here, we show for the first time that birds foraging on invertebrates contaminated with environmental pollutants, show marked changes in both brain and behaviour. We found that male European starlings (Sturnus vulgaris) exposed to environmentally relevant levels of synthetic and natural estrogen mimics developed longer and more complex songs compared to control males, a sexually selected trait important in attracting females for reproduction. Moreover, females preferred the song of males which had higher pollutant exposure, despite the fact that experimentally dosed males showed reduced immune function. We also show that the key brain area controlling male song complexity (HVC) is significantly enlarged in the contaminated birds. This is the first evidence that environmental pollutants not only affect, but paradoxically enhance a signal of male quality such as song. Our data suggest that female starlings would bias their choice towards exposed males, with possible consequences at the population level. As the starling is a migratory species, our results suggest that transglobal effects of pollutants on terrestrial vertebrate physiology and reproduction could occur in birds.

Song as an honest signal of developmental stress in the zebra finch (Taeniopygia guttata)

In a wide range of bird species, females have been shown to express active preferences for males that sing more complex songs. Current sexual selection theory predicts that for this signal to remain an honest indicator of male quality, it must be associated with an underlying cost of development or maintenance. There has been considerable debate questioning the costs associated with song production and learning. Recently, the nutritional stress hypothesis proposed that song complexity could act as an indicator of early developmental history, since the song control nuclei in the brain are laid down early in life. Here we test the nutritional stress hypothesis, by investigating the effects of dietary stress on the quality of adult song produced. In addition, we tested the effects of elevated corticosterone during development on song production to test its possible involvement in mediating the effects of developmental stress. The results demonstrate that both dietary restriction and elevated corticosterone levels significantly reduced nestling growth rates. In addition, we found that experimentally stressed birds developed songs with significantly shorter song motif duration and reduced complexity. These results provide novel experimental evidence that complex song repertoires may have evolved as honest signals of male quality, by indicating early developmental rearing conditions.

Living with amyotrophic lateral sclerosis/motor neurone disease (ALS/MND) : decision-making about 'ongoing change and adaptation

Aims and objectives. To present a model that explicates the dimensions of change and adaptation as revealed by people who are diagnosed and live with amyotrophic lateral sclerosis/motor neurone disease.

Background. Most research about amyotrophic lateral sclerosis/motor neurone disease is medically focused on cause and cure for the illness. Although psychological studies have sought to understand the illness experience through questionnaires, little is known about the experience of living with amyotrophic lateral sclerosis/motor neurone disease as described by people with the disease.

Design. A grounded theory method of simultaneous data collection and constant comparative analysis was chosen for the conduct of this study.

Methods. Data collection involved in-depth interviews, electronic correspondence, field notes, as well as stories, prose, songs and photographs important to participants. QSR NVivo 2® software was used to manage the data and modelling used to illustrate concepts.

Findings. Participants used a cyclic, decision-making pattern about 'ongoing change and adaptation' as they lived with the disease. This pattern formed the basis of the model that is presented in this paper.

Conclusion. The lives of people living with amyotrophic lateral sclerosis/motor neurone disease revolve around the need to make decisions about how to live with the disease progression and their deteriorating abilities. Life decisions were negotiated by participants to maintain a sense of self and well-being in the face of change.

Relevance to clinical practice. The 'ongoing change and adaptation' model is a framework that can guide practitioners to understand the decision-making processes of people living with amyotrophic lateral sclerosis/motor neurone disease. Such understanding will enhance caring and promote models of care that are person-centred. The model may also have relevance for people with other life limiting diseases and their care.

Developmental stress selectively affects the song control nucleus HVC in the zebra finch brain

Songbirds sing complex songs as a result of evolution through sexual selection. The evolution of such sexually selected traits requires genetic control, as well as selection on their expression. Song is controlled by a discrete neural pathway in the brain, and song complexity has been shown to correlate with the volume of specific song control nuclei. As such, the development of these nuclei, in particular the high vocal centre (HVC), is thought to be the mechanism controlling signal expression indicating male quality. We tested the hypothesis that early developmental stress selectively affects adult HVC size, compared with other brain nuclei. We did this by raising cross–fostered zebra finches (Taeniopygia guttata) under stressed and controlled conditions and determining the effect on adult HVC size. Our results confirm the strong influence of environmental conditions, particularly on HVC development, and therefore on the expression of complex songs. The results also show that both environmental and genetic factors affect the development of several brain nuclei, highlighting the developmental plasticity of the songbird brain. In all, these results explain how the complex song repertoires of songbirds can evolve as honest indicators of male quality.

Parasites affect song complexity and neural development in a songbird

There is now considerable evidence that female choice drives the evolution of song complexity in many songbird species. However, the underlying basis for such choice remains controversial. The developmental stress hypothesis suggests that early developmental conditions can mediate adult song complexity by perturbing investment in the underlying brain nuclei during their initial growth. Here, we show that adult male canaries (Serinus canaria), infected with malaria (Plasmodium relictum) as juveniles, develop simpler songs as adults compared to uninfected individuals, and exhibit reduced development of the high vocal centre (HVC) song nucleus in the brain. Our results show how developmental stress not only affects the expression of a sexually selected male trait, but also the structure of the underlying song control pathway in the brain, providing a direct link between brain and behaviour. This novel experimental evidence tests both proximate and ultimate reasons for the evolution of complex songs and supports the Hamilton–Zuk hypothesis of parasite-mediated sexual selection. Together, these results propose how developmental costs may help to explain the evolution of honest advertising in the complex songs of birds.

Developmental stress, social rank and song complexity in the European starling (Sturnus vulgaris)

Bird song is a sexually selected trait and females have been shown to prefer males that sing more complex songs. However, for repertoire size to be an honest signal of male quality it must be associated with some form of cost. This experiment investigates the effects of food restriction and social status during development on song complexity in the European starling (Sturnus vulgaris). Birds that experienced an unpredictable food supply early in life produced a significantly smaller repertoire of song phrases than those with a constant food supply. Social status during development was also significantly correlated with repertoire size, with dominant birds producing more phrase types. This study therefore provides novel evidence that social as well as nutritional history may be important in shaping the song signal in this species.

Developmental stress affects the attractiveness of male song and female choice in the zebra finch (Taeniopygia guttata)

Developmental stress has recently been shown to have adverse effects upon adult male song structure in birds, which may well act as an honest signal of male quality to discriminating females. However, it still remains to be shown if females can discriminate between the songs of stressed and non-stressed males. Here we use a novel experimental design using an active choice paradigm to investigate preferences in captive female zebra finches (Taeniopygia guttata). Nine females were exposed to ten pairs of songs by previously stressed and non-stressed birds that had learned their song from the same tutor. Song pairs differed significantly in terms of song complexity, with songs of stressed males exhibiting lower numbers of syllables and fewer different syllables in a phrase. Song rate and peak frequency did not differ between stressed and non-stressed males. Females showed a significant preference for non-stressed songs in terms of directed perching activity and time spent on perches. Our results therefore indicate that developmental stress affects not only the structure of male song, but that such structural differences are biologically relevant to female mate choice decisions.

Not the holocaust memorial

Evoking Genocide compiles more than sixty short essays written by leading scholars and activists in the field of genocide studies. These authors pay eloquent tribute to the works of art and media that influenced their engagement with genocide and crimes against humanity. The subjects include books and stories, films, songs, drawings, documents, monuments, sculptures, personal testimonies, and even a Lego set. In an accessible and often deeply personal way, contributors explore their own relationships with the works in question. Edited by Adam Jones, recently selected as one of fifty key thinkers in Holocaust and genocide studies, Evoking Genocide makes an important contribution to the study of the art and culture of mass atrocity.

Vocal mimicry in songbirds

Baylis (1982, Acoustic Communication in Birds, Academic Press) decried the serious lack of experimental verification for the various hypotheses proposed to explain vocal mimicry in songbirds. With few exceptions, our understanding of the function and acquisition of this fascinating behaviour seems to have scarcely progressed. We examine the proposed functional explanations and supporting evidence, and summarize advances made since Baylis's (1982) review. We conclude that there is no compelling evidence to support any of the functional hypotheses but, rather, that almost all of the data concerning song mimicry are consistent with the learning mistakes hypothesis, whereby birds learn simple and common sounds, frequently using them in inappropriate contexts. Additionally, many apparently mimicked sounds are calls, not songs, which themselves may not be learned by the models. It is plausible that many examples of call mimicry are, in fact, due to evolutionary convergence.

Story vessels

Twelve sculptors were chosen to research and create a story vessel to represent the stories of the twelve wards of The City of Greater Geelong. I organised the community meetings for nine of the sculptors including myself.  This involved facilitating 27 meetngs.  I then documented and curated the exhibition of the twelve story vessels at three locations (Geelong City Hall, Johnstone Park and Federation Square).  This was part of the project called Connecting Identities in which other artists consulted with other communities to record stories, write and compose songs, poetry and performance art.

Amazing shapes : chirality

The use of songs to help learning of content is consistent with multi-sensory models of learning. Here, a song to the tune of “Amazing Grace” can be used in the classroom to enhance the learning of chirality and the Cahn-Ingold-Prelog priority rules.
