The expected background spectrum in NaI dark matter detectors and the DAMA result

Detailed Monte Carlo simulations of the expected radioactive background rates and spectra in NaI crystals are presented. The obtained spectra are then compared to those measured in the DAMA/NaI and DAMA/LIBRA experiments. The simulations can be made consistent with the measured DAMA spectrum only by assuming higher than reported concentrations of some isotopes and even so leave very little room for the dark matter signal. We conclude that any interpretation of the annual modulation of the event rate observed by DAMA as a dark matter signal, should include full consideration of the background spectrum. This would significantly restrict the range of dark matter models capable of explaining the modulation effect.Comment: 17 pages, 6 figure

Boys and girls come out to play: Gender differences in children\u27s play patterns

This paper presents findings from The Irish Neighbourhood Play Study; a national, cross-border research project which recorded children’s play patterns in Ireland during 2012. The study incorporated 1688 families across 240 communities. This study recorded the play patterns of children in Ireland aged birth-14 years. The findings of the study are discussed here in the context of gendered patterns. Particular emphasis is placed on the skill differences developed through various play choices. These differences are explored within the context of established literature on the learning strengths of boys and girls. Established bodies of literature on children’s learning across gender lines has long been engaged in the debate about whether these differences are biological or socially constructed. This paper offers a parallel question; Are gender differences within learning, constructed through play choices within childhood? ©IATED (2017). Reproduced in Research Online with permission

The age of imagination: imagining play and invention: implications for creative development

This paper presents findings from The Irish Neighbourhood Play Study; a national, cross-border research project which recorded children’s play patterns in Ireland during 2012. The study incorporated 1688 families across 240 communities. Data was established on the play choices of children aged from birth to 14 years. Multiple differentials were explored including socio-economic and geographical environments. This paper focuses on the findings within imaginary play patterns for the full cohort. As such, it presents the play patterns for imaginary play in children aged birth-14 years. The findings are discussed in the context of developmental patterns with particular emphasis on the relationship between imaginary play and the development of creativity. Creativity is a key concept within contemporary education. Its central nexus is problem solving in the face of uncertainty. Within a rapidly changing world, it is a key skill requirement for today’s children as they grow towards efficacy within instability. The relationship between the development of creativity and children’s engagement with imaginary play practices are explored in this paper. ©IATED (2017).

Children\u27s choices: the technology choices that children make within their free time. Influences and implications

The Irish Neighbourhood Play Research Project included almost 1700 families and 240 communities throughout Ireland. Using parental surveys and naturalistic observation, data was secured on how children in modern Ireland aged 0-14 are spending their free time. An all-island approach was taken incorporating cities, towns and rural areas across a variety of socio-economic groupings. Interesting findings arose from the data relating to the choices that children are making within their free time. This paper focuses on the choices they are making within technology use. Data on the children’s technological engagement will be presented and discussed through a child development lens. The positive and negative implications for both learning and development are raised. This generation of children will be the first to emerge into adulthood without ever experiencing a world without technology. For them, it will always have been central to their existence. What does this mean for the next generation of humanity? ©IATED (2016). Permission granted by IATED for inclusion in ResearchOnline@N

Let\u27s get real: are today\u27s children playing with nature? Do the educational aspirations of the nature play movement emerge within children\u27s neighbourhood play?

The Irish Neighbourhood Play Research Project was a large scale research project which included almost 1700 participant families and 240 communities throughout Ireland. It used parental surveys and naturalistic observation to secure data on how children in modern Ireland aged 0-15 are spending their free time. An all-island approach was taken incorporating cities, towns and rural areas across a variety of socio-economic groupings. Interesting findings arose from the data relating to the choices that children are making within their free time. This paper focuses on the choices they are making within their engagement with nature and natural materials. Data on the children’s nature choices will be presented and discussed through a child development lens. The positive and negative implications for both learning and development are raised. This leads us to interesting questions about the role of nature within child development and learning. As an international nature play movement gains ground in raising awareness about the importance of nature based learning and its linkages with educational structure and pedagogy, this research into children’s nature choices is timely ©IATED (2016).

The influences of opportunity. Differences in children\u27s play choices across diverse communities in Ireland

This paper presents findings from The Irish Neighbourhood Play Project; a research study initiated by IT Sligo and Early Childhood Ireland in 2012. The focus of this paper is on the data section which highlights children’s play choices and opportunities across socio-economic communities. The study incorporated almost 1800 families across 240 communities. Data was collected within disadvantaged communities, middle class communities and affluent communities. Where and what children are playing was investigated. The choices children and families make within play have a direct effect on the developing brain of the young child (Acar & Torquati, 2015). This, in turn, affects school performance and engagement. Choices however, are often framed by opportunities; opportunities are framed by government policy and investment in community facilities as well as socio-cultural norms. The data from this project shows that children across socio-economic divides are engaging in dramatically different play, experiences and activities. Key differences also emerged in relation to how children in diverse communities are engaging with technology. The differences across multiple themes are startling and offer insights into the breadth of childhood experience across the Island of Ireland. ©IATED (2017).

Is it time for the risky classroom? Dealing with risk and uncertainty is a natural part of adult life. Yet modern children are shielded from risk at every opportunity. A pedagogical shift is required

Risk within learning environments is a much debated topic within early childhood education. The sector sees and understands the benefits of risk but often remain risk adverse. No –one wishes for children to experience injury and as such safety measures are essential. However, risk has also been shown to be essential for holistic development and learning in the early years (Lights, 2014). It is very important in the formation of many important skills and contributes greatly to children’s holistic health (Brussoni, Olsen, Pike & Sleet, 2012). Contemporary research and the most up-to-date wisdom requires educators to embrace risk and risky play in order to maximise children’s learning opportunities (Brussoni et al, 2015). It is a type of play that supports the child to encounter and overcome challenge. It includes the development of self-belief in the face of adversity, resilience building and problem solving confidence as well as physical competence and survival skills. Taking risks also transfers into skills such as judgement and risk measurement as well as tenacity and the ability to try again after failure. But is risk endangered in modern childhood? This paper presents data from the Irish Neighbourhood Play Study. This study incorporated 1688 families across 240 communities. One of the things under investigation was the engagement with risk within neighbourhood play. The results indicate that the children were engaging in very low levels of risk. If the benefits of risk are to be experienced by this generation of children, educators may need to overcome their fears and reservations and learn to embrace and incorporate risk provision into Early Childhood pedagogies. ©IATED (2017).

Identifying invertebrate invasions using morphological and molecular analyses: North American Daphnia ‘pulex’ in New Zealand fresh waters

We used a DNA barcoding approach to identify specimens of the Daphnia pulex complex occurring in New Zealand lakes, documenting the establishment of non-indigenous North American Daphnia 'pulex'. Morphological delineation of species in this complex is problematic due to a lack of good morphological traits to distinguish the species, as there is a relatively high degree of morphological stasis within the group through evolutionary time. Accordingly, genetic analyses were used to determine the specific identity and likely geographic origin of this species. Morphologically, individuals most closely resembled Daphnia pulicaria or Daphnia pulex sensu lato, which cannot be separated morphologically. Furthermore, each of these taxa comprises separate species in North America and Europe, despite carrying the same names. We identified individuals using a 658 bp nucleotide portion of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) as North American Daphnia 'pulex', being distinct from European Daphnia pulex sensu stricto and D. pulicaria from Europe or North America. Cellulose allozyme electrophoresis was used to confirm that individuals were not hybrids with D. pulicaria. North American Daphnia 'pulex' in New Zealand were first recorded in New Zealand from South Island lakes that are popular for overseas recreational fishers, indicating a possible source of introduction for this species (e.g. on/in fishing gear). Our study provides an additional example of how genetic techniques can be used for the accurate identification of non-indigenous taxa, particularly when morphological species determination is not possible. The growth of global databases such as GenBank and Barcode of Life Datasystems (BOLD) will further enhance this identification capacity
