Exploring creativity and progression in transition through assessment is for learning

This paper provides an overview of the aims, methods and findings of the Capability and Progression in Transition through Assessment for Learning in Design and Technology (CAPITTAL-DT) project. This project, funded by Determined to Succeed Scotland, aimed to identify useful approaches to aid progression in creativity through the current initiative entitled 'Assessment is for learning' (AifL, SEED, 2002). AifL encourages learners and teachers to engage with assessment for, as, and of learning and adopt a range of strategies and ideas. The project team gathered baseline and follow up data from teachers and learners using questionnaires to gauge attitudes towards creativity, structured conceptual design activities to assess performance, learner evaluations and teacher interviews. The team concludes that there is scope for adopting the tools explored to support formative and sustainable assessment strategies and approaches to gathering meaningful indicators that can be embedded into enterprising teaching and learning for Design and Technology Education

Pink Slip: Southwestern Pennsylvania's Response to Workforce Reductions at US Airways, 2001-05

The unforgettable events of September 11, 2001, delivered a crushing blow to the U.S. Airline industry, which was already in a financially precarious position. Long after the temporary shutdown was over and operations had resumed, many people were reluctant to travel. The resulting loss of revenue, coupled with increased costs associated with new security measures, caused several major carriers to take drastic actions, including significant layoffs. This Case in Point examines how Southwestern Pennsylvania responded to five-year series of massive job losses at one of the region’s largest employers, US Airways

Attitudes toward peer assessment in initial teacher education students: an exploratory case study

This paper explores the attitudes of Design and Technology (D&T) initial teacher education students toward peer assessment. Through a small scale case study, the research uses a quasi-experimental approach to examine participant’s perception of peer assessment prior and subsequent to a set of experiential intervention activities that were designed to develop a democratic and dialogic conceptulisation of peer assessment rooted in critical pedagogy. It was hypothesised that exposure to these intervention activities might alter participant’s perceptions of the peer assessment process. Findings from the research suggest this hypothesis to be accurate and appear to reveal a change in participant attitudes to peer assessment from one dominated by teacher-centred, or didactic, understandings to one where the role of student voice should be central. The subsequent interpretation and discussion seeks to illuminate the value of understanding how such an approach to peer assessment might help develop learners’ growing ability to take responsibility for their own learning and contribute to developing D&T assessment practice

Questioning the design and technology paradigm

The pace of technological change means that the school subject of design and technology must be in the process of constantly reinventing itself. Yet the way that we are teaching has changed little since the beginnings of the subject. We are still delivering and assessing in the same ways we were 30 years ago. Why? The industries and philosophies which power our thinking have, and are, changing drastically. We would seem to be concerned to give citizens of tomorrow the new tools without the new ways of using them. Much vaunted issues like collaboration, creativity, sustainability and the reasons why we do what we do, are little questioned. The subject of design and technology would seem to be in a unique position to influence designers, consumers and citizens of the future. Ideas of learning and designing styles, choice and collaboration would seem to be the watchwords for the future. So how do we do it? As a group will share ideas and plans for ways of rethinking what we are about, therefore how we should enable the learners of the future and then how we should assess it. This will be a collaborative experiential session, which challenges the traditional perceptions of the keynote presentation and will be more theatrical than is conventionally done. The attatched paper is therefore a commentary to the presentations but will not be the text of the presentation. Those presentations will be members of the team giving the situation in role. There should be time within the questions session for idividuals in the audience who feel that we have polarised and misrepresented their positions to speak to the rest of the conference. In our abstract we hignlighted the areas of collaboration, creativity, sustainability and the philosophy of design and technology. The issues surrounding these missing links in our views were collaboration, creativity, sustainability, and philosophy

Association Testing of Previously Reported Variants in a Large Case-Control Meta-analysis of Diabetic Nephropathy

We formed the GEnetics of Nephropathy–an International Effort (GENIE) consortium to examine previously reported genetic associations with diabetic nephropathy (DN) in type 1 diabetes. GENIE consists of 6,366 similarly ascertained participants of European ancestry with type 1 diabetes, with and without DN, from the All Ireland-Warren 3-Genetics of Kidneys in Diabetes U.K. and Republic of Ireland (U.K.-R.O.I.) collection and the Finnish Diabetic Nephropathy Study (FinnDiane), combined with reanalyzed data from the Genetics of Kidneys in Diabetes U.S. Study (U.S. GoKinD). We found little evidence for the association of the EPO promoter polymorphism, rs161740, with the combined phenotype of proliferative retinopathy and end-stage renal disease in U.K.-R.O.I. (odds ratio [OR] 1.14, P = 0.19) or FinnDiane (OR 1.06, P = 0.60). However, a fixed-effects meta-analysis that included the previously reported cohorts retained a genome-wide significant association with that phenotype (OR 1.31, P = 2 × 10−9). An expanded investigation of the ELMO1 locus and genetic regions reported to be associated with DN in the U.S. GoKinD yielded only nominal statistical significance for these loci. Finally, top candidates identified in a recent meta-analysis failed to reach genome-wide significance. In conclusion, we were unable to replicate most of the previously reported genetic associations for DN, and significance for the EPO promoter association was attenuated

Motion dazzle and camouflage as distinct anti-predator defenses.

BACKGROUND: Camouflage patterns that hinder detection and/or recognition by antagonists are widely studied in both human and animal contexts. Patterns of contrasting stripes that purportedly degrade an observer's ability to judge the speed and direction of moving prey ('motion dazzle') are, however, rarely investigated. This is despite motion dazzle having been fundamental to the appearance of warships in both world wars and often postulated as the selective agent leading to repeated patterns on many animals (such as zebra and many fish, snake, and invertebrate species). Such patterns often appear conspicuous, suggesting that protection while moving by motion dazzle might impair camouflage when stationary. However, the relationship between motion dazzle and camouflage is unclear because disruptive camouflage relies on high-contrast markings. In this study, we used a computer game with human subjects detecting and capturing either moving or stationary targets with different patterns, in order to provide the first empirical exploration of the interaction of these two protective coloration mechanisms. RESULTS: Moving targets with stripes were caught significantly less often and missed more often than targets with camouflage patterns. However, when stationary, targets with camouflage markings were captured less often and caused more false detections than those with striped patterns, which were readily detected. CONCLUSIONS: Our study provides the clearest evidence to date that some patterns inhibit the capture of moving targets, but that camouflage and motion dazzle are not complementary strategies. Therefore, the specific coloration that evolves in animals will depend on how the life history and ontogeny of each species influence the trade-off between the costs and benefits of motion dazzle and camouflage.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Shared genetic origin of asthma, hay fever and eczema elucidates allergic disease biology

Asthma, hay fever (or allergic rhinitis) and eczema (or atopic dermatitis) often coexist in the same individuals, partly because of a shared genetic origin. To identify shared risk variants, we performed a genome-wide association study (GWAS; n = 360,838) of a broad allergic disease phenotype that considers the presence of any one of these three diseases. We identified 136 independent risk variants (P < 3 × 10-8), including 73 not previously reported, which implicate 132 nearby genes in allergic disease pathophysiology. Disease-specific effects were detected for only six variants, confirming that most represent shared risk factors. Tissue-specific heritability and biological process enrichment analyses suggest that shared risk variants influence lymphocyte-mediated immunity. Six target genes provide an opportunity for drug repositioning, while for 36 genes CpG methylation was found to influence transcription independently of genetic effects. Asthma, hay fever and eczema partly coexist because they share many genetic risk variants that dysregulate the expression of immune-related genes

New susceptibility loci associated with kidney disease in type 1 diabetes

WOS:000309817900008Diabetic kidney disease, or diabetic nephropathy (DN), is a major complication of diabetes and the leading cause of end-stage renal disease (ESRD) that requires dialysis treatment or kidney transplantation. In addition to the decrease in the quality of life, DN accounts for a large proportion of the excess mortality associated with type 1 diabetes (T1D). Whereas the degree of glycemia plays a pivotal role in DN, a subset of individuals with poorly controlled T1D do not develop DN. Furthermore, strong familial aggregation supports genetic susceptibility to DN. However, the genes and the molecular mechanisms behind the disease remain poorly understood, and current therapeutic strategies rarely result in reversal of DN. In the GEnetics of Nephropathy: an International Effort (GENIE) consortium, we have undertaken a meta-analysis of genome-wide association studies (GWAS) of T1D DN comprising ∼2.4 million single nucleotide polymorphisms (SNPs) imputed in 6,691 individuals. After additional genotyping of 41 top ranked SNPs representing 24 independent signals in 5,873 individuals, combined meta-analysis revealed association of two SNPs with ESRD: rs7583877 in the AFF3 gene (P = 1.2×10(-8)) and an intergenic SNP on chromosome 15q26 between the genes RGMA and MCTP2, rs12437854 (P = 2.0×10(-9)). Functional data suggest that AFF3 influences renal tubule fibrosis via the transforming growth factor-beta (TGF-β1) pathway. The strongest association with DN as a primary phenotype was seen for an intronic SNP in the ERBB4 gene (rs7588550, P = 2.1×10(-7)), a gene with type 2 diabetes DN differential expression and in the same intron as a variant with cis-eQTL expression of ERBB4. All these detected associations represent new signals in the pathogenesis of DN.Peer reviewe

Genome-wide association study of circulating interleukin 6 levels identifies novel loci

Interleukin 6 (IL-6) is a multifunctional cytokine with both pro- and anti-inflammatory properties with a heritability estimate of up to 61%. The circulating levels of IL-6 in blood have been associated with an increased risk of complex disease pathogenesis. We conducted a two-staged, discovery and replication meta genome-wide association study (GWAS) of circulating serum IL-6 levels comprising up to 67428 (ndiscovery=52654 and nreplication=14774) individuals of European ancestry. The inverse variance fixed effects based discovery meta-analysis, followed by replication led to the identification of two independent loci, IL1F10/IL1RN rs6734238 on chromosome (Chr) 2q14, (Pcombined=1.8x10-11), HLA-DRB1/DRB5 rs660895 on Chr6p21 (Pcombined=1.5x10-10) in the combined meta-analyses of all samples. We also replicated the IL6R rs4537545 locus on Chr1q21 (Pcombined=1.2x10-122). Our study identifies novel loci for circulating IL-6 levels uncovering new immunological and inflammatory pathways that may influence IL-6 pathobiology.</p
