Love, rights and solidarity: studying children's participation using Honneth's theory of recognition

Recent attempts to theorize children’s participation have drawn on a wide range of ideas, concepts and models from political and social theory. The aim of this article is to explore the specific usefulness of Honneth’s theory of a ‘struggle for recognition’ in thinking about this area of practice. The article identifies what is distinctive about Honneth’s theory of recognition, and how it differs from other theories of recognition. It then considers the relevance of Honneth’s conceptual framework to the social position of children, including those who may be involved in a variety of ‘participatory’ activities. It looks at how useful Honneth’s ideas are in direct engagement with young people’s praxis, drawing on ethnographic research with members of a children and young people’s forum. The article concludes by reflecting on the implications of this theoretical approach and the further questions which it opens up for theories of participation and of adult–child relations more generally

Combined lubricant-surface system perspective: multi-scale numerical-experimental investigation

Frictional losses are one of the main causes of reduced energy efficiency in all machines and mechanisms. In particular, there is mounting pressure upon manufacturers of all forms of vehicle to comply with increasingly stringent legislation and directives with regard to harmful emissions. Therefore, reduction of friction has become an imperative issue. The traditional approach of dealing with surface material and lubricant formulation in isolation has been replaced by a lubricant–surface system approach. This paper presents multi-scale experimentation from nano/meso-scale lateral force microscopy of ultra-thin surface adsorbed films through to micro-scale precision sliding tribometry to investigate lubricant–surface friction optimisation within the mixed regime of lubrication, using lubricants with different organic and inorganic friction modifying species. These affect the parameters of the system, commonly used as input to models for mixed and boundary regimes of lubrication. Therefore, the precise measurement of these parameters at different physical scales is important. The study also makes use of detailed numerical predictions at micro-scale through combined solution of the average Reynolds equation as well as interaction of wetted asperities in mixed and boundary regimes of lubrication. Good agreement is found between the predictions and measurements at micro-scale tribometric interactions. Furthermore, the same trends are observed in testing across the physical scales

Childhood Labor in India: issues and complexities

It is estimated that more than 12 million children in India under the age of 14 engage in paid labor at least part time, due mostly to economic reasons. Dominant discourses about childhood however conceptualize childhood labor not only as unethical but as exploitation. This article explored will the tensions between Western notions of childhood (within which paid labor is considered taboo) and the realities of children's lives in India, arguing that childhood labor must be contextualized and understood not only as a colonial legacy but also as part of its socio-cultural context. The author argues that separating children from the world of work fosters a culture of childhood that emphasizes entitlement over participation and privileges the rights of the consumer over children's rights as citizens

The translation of articles from the United Nations Convention on the Rights of the Child into education legislation:the narrowing of Article 12 as a consequence of translation

This paper is concerned with the inclusion, exclusion and reshaping of articles within the United Nations Convention on the Rights of the Child (CRC) as they are translated into English education legislation. The CRC comprises 54 articles aimed at outlining rights and freedoms for children and was ratified by the United Kingdom (UK) government in 1991. The paper builds on a previous publication by the authors which highlighted how the mobilisation of articles within the CRC into professional practice undergoes multiple translations. This paper takes an in‐depth and critical look at the first stage of the translation process in which articles are mobilised from the CRC into national legislation. Specifically, the paper presents findings from a documentary analysis which explored the translation of principles pertaining to Article 12 of the CRC into English Education Regulations, Acts and Statutory Guidance for schools. Findings demonstrate that the reshaping of the article within education legislation strongly reflects the government's priorities and agendas. The study raises new insights into the need to establish processes to ensure the full mobilisation of Article 12 and questions whether specific principles pertaining to the article could or should be incorporated into national legislative systems.Output Status: Forthcoming/Available Onlin

Seeking children's perspectives: a respectful layered research approach

This article discusses why researchers and educators might choose to seek children's perspectives. It also highlights some of the key considerations when seeing children as having the right to contribute to decisions that affect them. The article draws on findings from a study that used pedagogically oriented methods for researching three- and four-year-old children's perspectives about outdoor spaces in the early childhood setting they attended. The article discusses the possibilities and practicalities of this research approach for both research and pedagogy. Examples are provided for others who may be considering working/researching in these ways

Fine-Scale in Situ Measurement of Riverbed Nitrate Production and Consumption in an Armored Permeable Riverbed

Alteration of the global nitrogen cycle by man has increased nitrogen loading in waterways considerably, often with harmful consequences for aquatic ecosystems. Dynamic redox conditions within riverbeds support a variety of nitrogen transformations, some of which can attenuate this burden. In reality, however, assessing the importance of processes besides perhaps denitrification is difficult, due to a sparseness of data, especially in situ, where sediment structure and hydrologic pathways are intact. Here we show in situ within a permeable riverbed, through injections of 15N-labeled substrates, that nitrate can be either consumed through denitrification or produced through nitrification, at a previously unresolved fine (centimeter) scale. Nitrification and denitrification occupy different niches in the riverbed, with denitrification occurring across a broad chemical gradient while nitrification is restricted to more oxic sediments. The narrow niche width for nitrification is in effect a break point, with the switch from activity “on” to activity “off” regulated by interactions between subsurface chemistry and hydrology. Although maxima for denitrification and nitrification occur at opposing ends of a chemical gradient, high potentials for both nitrate production and consumption can overlap when groundwater upwelling is strong

Value/s in early childhood education

Twenty years ago, as an early childhood teacher, I was fortunate to attend a professional development day conference led by the inimitable Professor Tina Bruce. At the conference, Tina asked we early childhood teachers: ‘What one thing would you put your back to the wall for in your job?’ In other words, Tina wanted us to share with one another the values that guide our daily work with young children and their families. An avowed Froebelian, Tina herself subscribes to a very particular set of values (Bruce 2015) and she is not alone. Many early childhood educators over two centuries have been influenced by the principles and philosophy developed by Froebel, the original kindergarten practitioner (Froebel Trust 2018). Indeed, as for so many others, my own initial teacher education was strongly influenced by Froebelian principles which have continued to guide my work in the field for thirty-five years. We live in an era of unprecedented global focus on early childhood development (UNESCO 2017; WHO 2018), in this editorial I revisit Froebel’s principles and I argue that we would be wise to continue to regard them as relevant and valuable touchstones for early childhood education in the twenty-first century

Enhanced hyporheic exchange flow around woody debris does not increase nitrate reduction in a sandy streambed

Anthropogenic nitrogen pollution is a critical problem in freshwaters. Although riverbeds are known to attenuate nitrate, it is not known if large woody debris (LWD) can increase this ecosystem service through enhanced hyporheic exchange and streambed residence time. Over a year, we monitored the surface water and pore water chemistry at 200 points along a ~50m reach of a lowland sandy stream with three natural LWD structures. We directly injected 15N-nitrate at 108 locations within the top 1.5m of the streambed to quantify in situ denitrification, anammox and dissimilatory nitrate reduction to ammonia, which, on average, contributed 85%, 10% and 5% of total nitrate reduction, respectively. Total nitrate reducing activity ranged from 0-16µM h-1 and was highest in the top 30cm of the stream bed. Depth, ambient nitrate and water residence time explained 44% of the observed variation in nitrate reduction; fastest rates were associated with slow flow and shallow depths. In autumn, when the river was in spate, nitrate reduction (in situ and laboratory measures) was enhanced around the LWD compared with non-woody areas, but this was not seen in the spring and summer. Overall, there was no significant effect of LWD on nitrate reduction rates in surrounding streambed sediments, but higher pore water nitrate concentrations and shorter residence times, close to LWD, indicated enhanced delivery of surface water into the streambed under high flow. When hyporheic exchange is too strong, overall nitrate reduction is inhibited due to short flow-paths and associated high oxygen concentrations
