Reconciling the supply of and demand for carbon cycle science in the US agricultural sector

When asking the question, ``How can institutions design science policies for the benefit of decision makers?'' Sarewitz and Pielke Sarewitz, D., Pielke Jr., R.A., this issue. The neglected heart of science policy: reconciling supply of and demand for science. Environ. Sci. Policy 10] posit the idea of ``reconciling supply and demand of science'' as a conceptual tool for assessment of science programs. We apply the concept to the U.S. Department of Agriculture's (USDA) carbon cycle science program. By evaluating the information needs of decision makers, or the ``demand'', along with the supply of information by the USDA, we can ascertain where matches between supply and demand exist, and where science policies might miss opportunities. We report the results of contextual mapping and of interviews with scientists at the USDA to evaluate the production and use of current agricultural global change research, which has the stated goal of providing ``optimal benefit'' to decision makers on all levels. We conclude that the USDA possesses formal and informal mechanisms by which scientists evaluate the needs of users, ranging from individual producers to Congress and the President. National-level demands for carbon cycle science evolve as national and international policies are explored. Current carbon cycle science is largely derived from those discussions and thus anticipates the information needs of producers. However, without firm agricultural carbon policies, such information is currently unimportant to producers. (C) 2006 Elsevier Ltd. All rights reserved.

48 Hour Game Making Challenge - In Progress [Four Episodes]

Statement: Jams, Jelly Beans and the Fruits of Passion Let us search, instead, for an epistemology of practice implicit in the artistic, intuitive processes which some practitioners do bring to situations of uncertainty, instability, uniqueness, and value conflict. (Schön 1983, p40) Game On was born out of the idea of creative community; finding, networking, supporting and inspiring the people behind the face of an industry, those in the mist of the machine and those intending to join. We understood this moment to be a pivotal opportunity to nurture a new emerging form of game making, in an era of change, where the old industry models were proving to be unsustainable. As soon as we started putting people into a room under pressure, to make something in 48hrs, a whole pile of evolutionary creative responses emerged. People refashioned their craft in a moment of intense creativity that demanded different ways of working, an adaptive approach to the craft of making games – small – fast – indie. An event like the 48hrs forces participants’ attention on the process as much as the outcome. As one game industry professional taking part in a challenge for the first time observed: there are three paths in the genesis from idea to finished work: the path that focuses on mechanics; the path that focuses on team structure and roles and the path that focuses on the idea, the spirit – and the more successful teams need to put the spirit of the work first and foremost. The spirit drives the adaptation, it becomes improvisation. As Schön says: “Improvisation consists on varying, combining and recombining a set of figures within the schema which bounds and gives coherence to the performance.” (1983, p55). This improvisational approach is all about those making the games: the people and the principles of their creative process. This documentation evidences the intensity of their passion, determination and the shit that they are prepared to put themselves through to achieve their goal – to win a cup full of jellybeans and make a working game in 48hrs. 48hr is a project where, on all levels, analogue meets digital. This concept was further explored through the documentation process. This set of four videos were created by Cameron Owen on the fly during the challenge using both the iphone video camera and editing software in order to be available with immediacy and allow the event audience to share the experience - and perhaps to give some insights into the creative process exposed by the 48 hour challenge. ____________________________ Schön, D.

The Fifth 48 Hour Game Making Challenge (2011)

The 48-hour game making challenge started out in 2007 as a creative community event. We have run this event each year since and seen over 120 games made. 2011 was the most remarkable in that each of the 20 teams made a playable game – the shape of the challenge has changed …. We have invested in the process of reflective practice & action research, with the event being part of a sweep of programs that inform this research, with each year giving us fresh insights into both the creative practice and essential concerns, process and trends of the independent games industry creative community, which we then respond to within our curatorial development of the subsequent programming. The 2011 48-hour challenge research project focused on the people and the site. We were specifically interested in the manner in which the community occupied the creative space.

Visualising the 48 hour game making challenge

We have always felt that “something very special” was happening in the 48hr and other similar game jams. This “something” is more than the intensity and challenge of the experience, although this certainly has appeal for the participants. We had an intuition that these intense 48 hour game jams exposed something pertinent to the changing shape of the Australian games industry where we see the demise of the late 20th century large studio - the “Night Elf” model and the growth of the small independent model. There are a large number of wider economic and cultural factors around this evolution but our interest is specifically in the change from “industry” to “creative industry” and the growth of games as a cultural media and art practice. If we are correct in our intuition, then illuminating this something also has important ramifications for those courses which teach game and interaction design and development. Rather than undertake a formal ethno-methodological approach, we decided to track as many of the actors in the event as possible. We documented the experience (Keith Novak’s beautiful B&W photography), the individual and their technology (IOGraph mouse tracking), the teams as a group (Time lapse photography) and movement tracking throughout the whole space (Blue tooth phone tracking). The raw data collected has given us opportunity to start a commentary on the “something special” happening in the 48hr.

Ureaplasma speioces are associated with chorioamnionitiis in late preterm placentas

Background: Preterm birth is a major cause of neonatal morbidity and mortality, with 75% of preterm births occurring late preterm. Previous studies have investigated the microbial diversity within placentas delivered early preterm but there has been no investigation of the prevalence of bacteria, particularly Ureaplasma spp. in late preterm placentas. Method: Women giving birth late preterm (320 – 366 weeks of gestation) in Cincinnati were recruited for this study. Samples of chorioamnion were collected aseptically at the time of delivery, shipped to QUT and tested for Ureaplasma spp. and other bacteria by culture and/or PCR assays. The presence of bacteria was correlated with adverse pregnancy outcomes, including histological chorioamnionitis (tissue sections read by US pathologists). Results: To date, Ureaplasma spp. have been detected in 15/270 (5.5%) of placentas by culture and 19/270 (7%) by PCR. Ureaplasma presence correlated with histological chorioamnionitis (12/19%; 63%). However, the presence of other bacteria was not associated with chorioamnionitis (5%). Chorioamnionitis was unevenly distributed in ethnic groups, with a higher incidence in African-Americans’ (6/7; 86%), compared to Caucasians’ (6/12; 50%) who were colonised with ureaplasmas. Conclusion: This study is the first to report the prevalence of ureaplasmas in women (7%) who deliver late preterm. Ureaplasma spp. were associated with a higher incidence of chorioamnionitis (63% compared to 15% for non-infected women). This data strongly suggests that ureaplasmas are a cause of late preterm deliveries and African-American women are at greater risk of chorioamnionitis.

Improved linear cryptanalysis of reduced-round SIMON-32 and SIMON-48

In this paper we analyse two variants of SIMON family of light-weight block ciphers against variants of linear cryptanalysis and present the best linear cryptanalytic results on these variants of reduced-round SIMON to date. We propose a time-memory trade-off method that finds differential/linear trails for any permutation allowing low Hamming weight differential/linear trails. Our method combines low Hamming weight trails found by the correlation matrix representing the target permutation with heavy Hamming weight trails found using a Mixed Integer Programming model representing the target differential/linear trail. Our method enables us to find a 17-round linear approximation for SIMON-48 which is the best current linear approximation for SIMON-48. Using only the correlation matrix method, we are able to find a 14-round linear approximation for SIMON-32 which is also the current best linear approximation for SIMON-32. The presented linear approximations allow us to mount a 23-round key recovery attack on SIMON-32 and a 24-round Key recovery attack on SIMON-48/96 which are the current best results on SIMON-32 and SIMON-48. In addition we have an attack on 24 rounds of SIMON-32 with marginal complexity.

Shared genetics underlying epidemiological association between endometriosis and ovarian cancer

Epidemiological studies have demonstrated associations between endometriosis and certain histotypes of ovarian cancer, including clear cell, low-grade serous and endometrioid carcinomas. We aimed to determine whether the observed associations might be due to shared genetic aetiology. To address this, we used two endometriosis datasets genotyped on common arrays with full-genome coverage (3194 cases and 7060 controls) and a large ovarian cancer dataset genotyped on the customized Illumina Infinium iSelect (iCOGS) arrays (10 065 cases and 21 663 controls). Previous work has suggested that a large number of genetic variants contribute to endometriosis and ovarian cancer (all histotypes combined) susceptibility. Here, using the iCOGS data, we confirmed polygenic architecture for most histotypes of ovarian cancer. This led us to evaluate if the polygenic effects are shared across diseases. We found evidence for shared genetic risks between endometriosis and all histotypes of ovarian cancer, except for the intestinal mucinous type. Clear cell carcinoma showed the strongest genetic correlation with endometriosis (0.51, 95% CI = 0.18–0.84). Endometrioid and low-grade serous carcinomas had similar correlation coefficients (0.48, 95% CI = 0.07–0.89 and 0.40, 95% CI = 0.05–0.75, respectively). High-grade serous carcinoma, which often arises from the fallopian tubes, showed a weaker genetic correlation with endometriosis (0.25, 95% CI = 0.11–0.39), despite the absence of a known epidemiological association. These results suggest that the epidemiological association between endometriosis and ovarian adenocarcinoma may be attributable to shared genetic susceptibility loci.

Relação da apneia obstrutiva do sono com a função endotelial, estresse oxidativo, biomarcadores inflamatórios, perfil metabólico e atividade simpática em indivíduos obesos

Introdução: a apneia obstrutiva do sono (AOS) é considerada um fator de risco para as doenças cardiovasculares. Os mecanismos responsáveis pelo desenvolvimento da aterosclerose potencializados pela AOS não são completamente conhecidos. Entretanto, existem evidências de que a AOS está associada com aumento no estresse oxidativo, elevação nos mediadores inflamatórios, resistência à insulina, ativação do sistema nervoso simpático, elevação da pressão arterial (PA) e a disfunção endotelial. Objetivo: avaliar a relação da AOS com a função endotelial, o estresse oxidativo, os biomarcadores inflamatórios, o perfil metabólico, a adiposidade corporal, a atividade simpática e a PA em indivíduos obesos. Métodos: estudo transversal envolvendo 53 pacientes obesos, com índice de massa corporal (IMC) ≥ 30 e < 40 Kg/m2, sem distinção de raça e gênero, apresentando idade entre 20 e 55 anos. O estudo do sono foi realizado com o equipamento Watch-PAT 200, sendo feito o diagnóstico de AOS quando índice apneia-hipopneia (IAH) ≥ 5 eventos/h. Todos os participantes foram submetidos à avaliação do (a): adiposidade corporal (peso, % gordura corporal e circunferências da cintura, quadril e pescoço); PA; atividade do sistema nervoso simpático (concentrações plasmáticas de catecolaminas); biomarcadores inflamatórios (proteína C reativa ultrassensível (PCR-us) e adiponectina); estresse oxidativo (malondialdeído); metabolismo glicídico (glicose, insulina e HOMA-IR) e lipídico (colesterol total e frações e triglicerídeos); e função endotelial (índice de hiperemia reativa (RHI) avaliado com o equipamento Endo-PAT 2000 e moléculas de adesão celular). A análise estatística foi realizada com o software STATA versão 10. Resultados: dos 53 pacientes avaliados 20 foram alocados no grupo sem AOS (grupo controle; GC) (IAH: 2,550,35 eventos/h) e 33 no grupo com AOS (GAOS) (IAH: 20,163,57 eventos/h). A faixa etária (39,61,48 vs. 32,52,09 anos) e o percentual de participantes do gênero masculino (61% vs. 25%) foram significativamente maiores no GAOS do que no GC (p=0,01). O GAOS em comparação o GC apresentou valores significativamente mais elevados de circunferência do pescoço (CP) (40,980,63 vs. 38,650,75 cm; p=0,02), glicemia (92,541,97 vs. 80,21,92 mg/dL; p=0,0001), PA sistólica (126,051,61 vs.118,16 1,86 mmHg; p=0,003) e noradrenalina (0,160,02 vs. 0,120,03 ng/mL; p=0,02). Após ajustes para fatores de confundimento, a glicose e a PCR-us foram significativamente mais elevadas no GAOS. Os 2 grupos apresentaram valores semelhantes de IMC, insulina, HOMA-IR, perfil lipídico, adiponectina, PA diastólica, adrenalina, dopamina, moléculas de adesão celular e malondialdeído. A função endotelial avaliada pelo RHI também foi semelhante nos 2 grupos (GAOS:1,850,2 vs. GC:1,980,1; p=0,31). Nas análises de correlação, considerando todos os participantes do estudo, o IAH apresentou associação positiva e significativa com CP e PCR-us após ajustes para fatores de confundimento. A saturação mínima de O2 se associou de forma negativa e significativa com a CP, os níveis séricos de insulina e o HOMA-IR, mesmo após ajustes para fatores de confundimento. Conclusões: o presente estudo sugere que em obesos a AOS está associada com valores mais elevados de glicemia e inflamação; o aumento do IAH apresenta associação significativa com a obesidade central e com a inflamação; e a queda na saturação de oxigênio se associa com resistência à insulina.

Comparação interlaboratorial entre metodologias e estabilidade da amostra na dosagem do perfil lipídico e PCR-US

Segundo O`Kane et al, em 2008, foi demonstrado que 88,9% dos erros laboratoriais são realizados na fase pré-analítica. No laboratório de análises clínicas, o sistema de controle da qualidade pode ser definido como toda a ação sistemática necessária para dar confiança e segurança em todos os exames e prevenir a ocorrência de erros. O tempo de armazenamento pode variar de dias a meses ou mesmo anos, influenciando na definição da temperatura de estocagem. O armazenamento de longo prazo pode resultar na criopreservação inadequada para determinados analitos e pode desnaturar as lipoproteínas. Objetivos: Este trabalho teve como objetivo avaliar a fase pré-analítica, controle da qualidade interno e também avaliar o efeito do congelamento (- 80C) quanto ao tempo de armazenamento do soro e plasma de sangue colhido com ácido etilenodiamino tetra-acético (EDTA). As dosagens foram realizadas no Laboratório de Lípides LabLip, e estocadas em - 80 C por três anos, as mesmas foram redosadas no Serviço de Patologia Clínica da Policlínica Piquet Carneiro da UERJ com metodologias iguais e realizada a comparabilidade dos resultados. Foram analisados o perfil lipídico (CT, HDLc e TG) e PCR-US de 103 amostras, 73 no soro e 30 no plasma em dois laboratórios altamente qualificados. Discussão: Após redosagem foram encontrados nas dosagens de HDLc e CT resultados diminuídos respectivamente (correlação coeficiente no soro 0,48 e 0,62) teste t pareado no soro (CT p 0,0012 e HDLc p 0,0001). Conclusões: Os dados obtidos nas avaliações dos resultados de diferentes laboratórios e tempo de estocagem revelaram que as amostras quando armazenadas por um longo período após redosagem no soro, apresentaram diferenças em certos analitos, tais como CT e HDLc, no qual obteve-se resultados significativamente diminuídos, diferentemente no plasma, que após três anos de estocagem a -80C foram redosados e aplicados no teste t pareado, os analitos CT e PCR-US mantiveram a estabilidade.
