We're Creative on a Friday Afternoon: Investigating Children's Perceptions of their Experience of Design & Technology in Relation to Creativity
In the last 15 years there has been an increased emphasis in both educational research and curriculum development upon investigating children's perspectives of their experience of learning. Children naturally have very particular and important insights to offer in helping us to develop our understanding of teaching and learning. However, research into children's perceptions in the field of primary Design & Technology education is still at a very early stage (Lunt in International handbook of research and development in technology education, Sense Publishers, Utrecht, 2009a). For example, in three reviews of educational research in Design & Technology (Kimbell in A guide to educational research, The Woburn Publishers, London, 1996; Eggleston in Teaching and learning design and technology: a guide to recent research and its applications, Continuum, London, 2000; Harris and Wilson in Designs on the curriculum? A review of the literature on the impact of design and technology in schools, Department for Education and Skills, London, 2003) there are only passing references made to eliciting and considering pupils' views and, in the studies where it does occur, it is used as a supplementary method of data collection rather than as a focus of research. The work which exists is smallscale and the majority of studies relate to secondary-aged pupils. The research that we have recently undertaken has tried to redress this gap. It has focused on primary children's (aged 9–11 years) perceptions of Design & Technology in general (Benson and Lunt in PATT 18 international conference on design and technology educational research: teaching and learning technological literacy in the classroom, University of Glasgow, Glasgow, 2007) and latterly creativity in Design & Technology. It has been claimed by many that Design & Technology is a 'creative' subject which develops children's creative abilities. This is a bold claim and one that needs careful consideration. This paper sets out a framework for thinking about creativity drawn from a review of the literature and uses evidence of children's perceptions of their experience of Design & Technology to compare practice with theory in an attempt to raise questions and issues relevant to both policy and practice.

Unraveling weak and short South Asian wet season in the Early Eocene warmth
The timing and causative factors underlying the Asian summer monsoon initiation remain contentious as recent proxy data and modeling studies suggested the existence of a wet-dry monsoon-like climate from the Cretaceous period. Leveraging an ensemble of deep-time climate simulations focused on the early Eocene (DeepMIP-Eocene), we show that the early Eocene Asian wet season was notably weaker and shorter than present-day in the absence of an elevated heat source like the Tibetan Plateau. The deficient upper-tropospheric meridional temperature gradient was insufficient to propel the seasonal northward migration of the rainband over South Asia. The weaker cross-equatorial moisture flow encountered obstruction of Gangdese mountain along the southern edge of Asia, leading to significant South Asian aridity. The enhanced greenhouse effect was inadequate to augment the seasonal circulation and rainfall variability to current levels. The altered wet and dry seasonality across South Asia during the early Eocene does not meet the criteria to be classified as a monsoon, suggesting that South Asian monsoon initiation is likely contingent upon a specific level of Tibetan Plateau upliftment.

Urinary Amino-Terminal Pro–C-Type Natriuretic Peptide: A Novel Marker of Chronic Kidney Disease in Diabetes
Chronic renal inflammation and fibrosis are common sequelae in diabetes mellitus (DM) and are major causes of premature mortality. Although upregulation of
expression occurs in response to renal inflammation in experimental animals, nothing is known of the molecular forms of C-type natriuretic peptide (CNP) products in urine of people with DM or links with renal function.
ProCNP products in urine were characterized with HPLC and a range of antisera directed to specific epitopes of amino-terminal proCNP (NTproCNP). The 5-kDa intact peptide was quantified in spot urine samples from healthy adults and 202 participants with DM selected to provide a broad range of renal function.
The predominant products of proCNP in urine were consistent with the 2-kDa fragment (proCNP 3-20) and a smaller peak of intact (5-kDa) fragment (proCNP 1-50, NTproCNP). No peaks consistent with bioactive forms (proCNP 82-103, 50-103) were identified. The urine NTproCNP to creatinine ratio (NCR) was more reproducible than the albumin to creatinine ratio (ACR) and strongly associated with the presence of chronic kidney disease. In models predicting independence, among 10 variables associated with renal function in DM, including plasma NTproCNP, only 3 (sex, ACR, and plasma creatinine) contributed to NCR.
Characterization of the products of proCNP in urine confirmed the presence of NTproCNP. In spot random urine from study participants with DM, NCR is inversely associated with estimated glomerular filtration rate. In contrast to ACR, NCR reflects nonvascular factors that likely include renal inflammation and fibrosis.
