Music to measure: symbolic representation in children's composition.

Eisner maintains that the arts education community needs "empirically grounded examples of artistic thinking related to the nature of the tasks students engage in, the material with which they work, the context's norms and the cues the teachers provide to advance their students' thinking" (2000, p. 217). This paper reflects on the results of collaborative action research between teachers and university researchers in New Zealand who have been investigating how children develop and refine their ideas and related skills in music. The paper focuses specifically on the results of action research in which the impact of symbolic representation on idea development and refinement in music is examined. It raises some issues and points of tension for generalist and specialist teachers when fostering creative idea development in music

Paradox and promise in joint school/university arts research

Collaborative university and school research projects are inevitably labour intensive endeavours that require the careful negotiation of trust and the joint development of critique of current practice. While this raises tension it also builds generative communities of inquiry that can enhance both theory and practice. This paper reports on an Arts project undertaken in primary classrooms between university staff and generalist teacher co-researchers focusing on children’s idea development in dance, drama, music and art. This two year project is briefly outlined and some issues that arise in school research are explored. Project collaborators need to exercise caution in their examination of practice and strive to resist premature closure. All parties need to hold the tension of apparent contradictions, being both interested (in effective Arts pedagogy) and disinterested (in order to heighten perception) so that they might ‘surprise themselves in a landscape of practice with which many are very familiar indeed’ (McWilliam 2004:14). These issues and paradoxes in collaborative research are considered alongside some particular processes that build school and university partnerships

Exploring children's development of ideas in music and dance

Eisner maintains that the Arts education community needs ‘empirically grounded examples of artistic thinking related to the nature of the tasks students engage in, the material with which they work, the context’s norms and the cues the teacher provides to advance their students’ thinking’ (2000:217). This paper reflects on preliminary results of a collaborative research project between teachers and university researchers that is investigating how children develop and refine arts-making ideas and related skills in Dance and Music in a small sample of schools in New Zealand. Factors such as the place of repetition in the development of ideas, the relevance of offers, the place of verbal and non-verbal communication in arts idea generation, and group work as an accepted ritual of practice, are explored and discussed

Developing non-verbal ways of knowing in dance: Collaborative school / university action research.

Gardner (1983, 1993) has long argued that education privileges certain intelligences, primarily the linguistic and the logical-mathematical. As the arts tend to emphasise ways of knowing outside these intelligences, their marginalised status is exacerbated. A recent two-year project in eight primary schools on dance, drama, music and visual art found that the non-verbal aspects of each art form warranted serious attention to investigate what it means to learn in the arts. In this paper we describe and discuss the results of an aspect of action research in dance from this larger research project. We demonstrate how movement can be used as the primary expressive mode of communication, as opposed to privileging the spoken word. Through the use of powerpoint and video, we provide an intriguing and innovative model for providing non-verbal feedback and feed forward in the dance classroom

Calcium intakes of New Zealand male and female adolescents

Background: Calcium requirements during adolescence are high due to rapid skeletal growth throughout this key life stage. Increased peak bone mass has been found to decrease risk of osteoporosis in later life. Peak bone mass achieved during adolescence is determined by the degree of positive calcium balance achieved in this period. Given the current burden of osteoporosis in the aged population of New Zealand, investigation of dietary calcium intake in adolescents could help contribute to optimal bone health as these adolescents move into adulthood. Objective: To assess the current dietary calcium intake of New Zealand male and female adolescents aged 15-18 years. Key food sources of dietary calcium will also be examined. Design: This cross-sectional cluster study carried out across 2019/20 collected data on demographics, dietary habits, food choices and motivations, weight loss methods and intentions using online questionnaires. The participant’s food and beverage intakes were assessed using two non-consecutive 24 hr dietary recalls. Dietary data was entered into the nutrient analysis software Foodworks, which calculated mean daily energy and calcium intake data for each participant. Prevalence of inadequate calcium intake was assessed using the Estimated Average Requirement (EAR) cut-point method. Results: A total of 266 females and 135 males participated in the study with calcium intake calculated for 243 females and 102 males. The majority of participants identified as New Zealand European or other (57% of males, 78% of females), with 32% of males identifying as Asian, compared to 3.4% of females. Mean (standard deviation) energy intakes were 10,077 kJ/day (3215) for males and 7959 kJ/day (1781) for females. Median (inter-quartile range) calcium intakes were 935 mg/day (656, 1222) for males and 711 mg/day (551,915) for females. Prevalence of inadequate calcium intake (based on EAR of 1050 mg/day) was 63% for males and 85% for females. Milk was the top food source contributor to calcium intake, providing 17% and 28% of average daily calcium for males and females respectively. Conclusion: Findings from this study reflect a high prevalence of inadequate calcium intakes in the New Zealand adolescent population, particularly in females. The results indicate there is likely a large proportion of adolescents who are at high risk of osteoporosis in later life. Dietitians should continuously consider practical ways to assist this population group in meeting such calcium high requirements. Further investigation into the calcium intake and correlating bone health specifically of this population within New Zealand may be required

Tracking biases : an update to the validity and reliability of alcohol retail sales data for estimating population consumption in Scotland

Purchase of the sales data was funded by the Scottish Government as part of the wider Monitoring and Evaluating Scotland's Alcohol Strategy portfolio of studies. Funding to pay the Open Access publication charges for this article was provided by NHS Health Scotland.Aims: To highlight the importance of monitoring biases when using retail sales data to estimate population alcohol consumption. Methods: Previously, we identified and where possible quantified sources of bias that may lead to under- or overestimation of alcohol consumption in Scotland. Here, we update findings by using more recent data and by quantifying emergent biases. Results: Underestimation resulting from the net effect of biases on population consumption in Scotland increased from -4% in 2010 to -7% in 2013. Conclusion: Biases that might impact on the validity and reliability of sales data when estimating population consumption should be routinely monitored and updated.Publisher PDFPeer reviewe

Caspase-2 Can Trigger Cytochrome c Release and Apoptosis from the Nucleus

The cysteine proteases specific for aspartic residues, known as caspases, are localized in different subcellular compartments and play specific roles during the regulative and the executive phase of the cell death process. Here we investigated the subcellular localization of caspase-2 in healthy cells and during the execution of the apoptotic program. We have found that caspase-2 is a nuclear resident protein and that its import into the nucleus is regulated by two different nuclear localization signals. We have shown that in an early phase of apoptosis caspase-2 can trigger mitochondrial dysfunction from the nucleus without relocalizing into the cytoplasm. Release of cytochrome c occurs in the absence of overt alteration of the nuclear pores and changes of the nuclear/cytoplasmic barrier. Addition of leptomycin B, an inhibitor of nuclear export, did not interfere with the ability of caspase-2 to trigger cytochrome c release. Only during the late phase of the apoptotic process can caspase-2 relocalize in the cytoplasm, as consequence of an increase in the diffusion limits of the nuclear pores. Taken together these data indicate the existence of a nuclear/mitochondrial apoptotic pathway elicited by caspase-2

Caspase-2-induced Apoptosis Is Dependent on Caspase-9, but Its Processing during UV- or Tumor Necrosis Factor-dependent Cell Death Requires Caspase-3

Mammalian caspases are a family of cysteine proteases that plays a critical role in apoptosis. We have analyzed caspase-2 processing in human cell lines containing defined mutations in caspase-3 and caspase-9. Here we demonstrate that caspase-2 processing, during cell death induced by UV irradiation, depends both on caspase-9 and caspase-3 activity, while, during TNF-alpha-dependent apoptosis, capase-2 processing is independent of caspase-9 but still requires caspase-3. In vitro procaspase-2 is the preferred caspase cleaved by caspase-3, while caspase-7 cleaves procaspase-2 with reduced efficiency. We have also demonstrated that caspase-2-mediated apoptosis requires caspase-9 and that cells co-expressing caspase-2 and a dominant negative form of caspase-9 are impaired in activating a normal apoptotic response and release cytochrome c into the cytoplasm. Our findings suggest a role played by caspase-2 as a regulator of the mitochondrial integrity and open questions on the mechanisms responsible for its activation during cell death

‘A false sense of security’? Understanding the role of the HPV vaccine on future cervical screening behaviour: a qualitative study of UK parents and girls of vaccination age

OBJECTIVES: The UK Human Papillomavirus (HPV) vaccination programme was introduced in 2008 for girls aged 12-13. The vaccine offers protection against HPV types 16 and 18, which together cause about 70% of cervical cancers. Vaccinated girls will receive future invitations to the NHS Cervical Screening Programme, to prevent cancers associated with HPV types not included in the vaccine, and in case of prior infection with HPV 16 or 18. Little is known about parents' and girls' understandings of the protection offered by the vaccine, or the need for future screening. DESIGN: Qualitative interviews with twenty-six parents, and nine girls aged 12-13 who were offered HPV vaccination through a Primary Care Trust (PCT) in the South-east of England, UK. SETTING: Thirty-nine schools, and four general practices. RESULTS: Uncertainty about the level of protection offered by the HPV vaccine was evident among parents, and to a lesser extent among vaccination-aged girls. There was a lack of understanding among parents and girls that cervical screening would be required irrespective of vaccination status; some parental decisions to accept the vaccine were made on the misunderstanding that vaccination provided complete protection against cervical cancer. CONCLUSIONS: Sufficient awareness of the issues related to screening is necessary for informed decision-making about whether or not to accept the HPV vaccine. Clearer information is needed concerning the incomplete protection offered by the vaccine, and that cervical screening will still be required. Future invitations for cervical screening should stress the necessity to attend regardless of HPV vaccination status, to ensure that high levels of prevention of cervical cancer through screening are maintained
