Longitudinal child data: What can be gained by linking administrative data and cohort data?

Abstract Introduction Linked administrative data sets are an emerging tool for studying the health and well-being of the population. Previous papers have described methods for linking Canadian data, although few have specifically focused on children, nor have they described linkage between tax outcomes and a cohort of children who are particularly at risk for poor financial outcomes. Objective and methods This paper describes a probabilistic linkage performed by Statistics Canada linking the Montreal Longitudinal Experimental Study (MLES) and the Quebec Longitudinal Study of Kindergarten Children (QLSKC) survey cohorts and administrative tax data from 1992 through 2012. Results The number of valid cases in the original cohort file with valid tax records was approximately 84%. Rates of false positives, false negatives, sensitivity, and specificity of the linkage were all acceptable. Using the linked file, the relationship of childhood behavioural indicators and adult income can be investigated in future studies. Conclusions Innovative methods for creating longitudinal datasets on children will assist in examining long-term outcomes associated with early childhood risk and protective factors as well as an evidence base for interventions that promote child well-being and positive outcomes.
Microgeographic variation in the effects of larval temperature environment on juvenile morphology and locomotion in the pool frog

In animals with complex life cycles, the environment experienced early during the development may have strong effects on later performance and fitness. We investigated the intraspecific variation in the effects of larval temperature environment on the morphology and locomotory performance of juvenile pool frogs Rana lessonae originating from three closely located populations of the northern fringe metapopulation in central Sweden. Tadpoles were raised individually at two temperatures (20 and 25 degrees C) until metamorphosis. We measured the morphology of the metamorphs and tested the jumping performance of the froglets after complete tail absorption. We found that early temperature environment affected juvenile morphology, metamorphs from high-temperature environments having relatively longer hindlimbs (tibiofibulas) and longer tails when weight at metamorphosis was accounted for. In absolute terms, froglets from low temperature jumped significantly longer; however, after correcting for size differences the relationship was reversed, individuals raised at high temperature performing better. In both temperatures, relative jumping performance was positively associated with tibiofibula and body length. Populations differed both in metamorphic traits and in jumping capacity, especially at low temperature, suggesting microgeographical variation in temperature sensitivity within the metapopulation. Our results indicate that the temperature environment experienced during the early aquatic stages can influence the morphology and performance of juvenile frogs, and that these effects can be population specific.
23 Thermal Conductivity of Nanoparticles Filled Polymers

Thermal conductivity of polymers is an important thermal property for both polymer applications and processing. Polymers typically have intrinsic thermal conductivity much lower than those for metals or ceramic materials, and therefore are good thermal insulators. Further enhancement of this thermal insulating quality can be achieved by foaming polymers. In other applications which require higher thermal conductivity, such as in electronic packaging and encapsulations, satellite devices, and in areas where good heat dissipation, low thermal expansion and light weight are needed, polymers reinforced with fillers, organic or inorganic, are becoming more and more common in producing advanced polymer composites for these applications (Hodgin & Estes, 1999; Tavman, 2004; Lee & Eun, 2004; Liu & Mather, 2004; Ishida & Heights, 1999; Frank & Phillip, 2002; Hermansen, 2001; Ishida, 2000). Most polymeric materials are processed and fabricated at elevated temperatures, often above their melting temperatures. This process may be long and expensive because of the low thermal conductivity of polymers. Subsequently, the cooling process or annealing may also be controlled by heat transport properties of polymers, which eventually affect the physical properties of the materials. One example is crystalline polymers, for which the structural and morphological features may be significantly changed with the speed of cooling. Careful consideration in designing polymer processing is vital to achieve desired properties.
Personality Traits and the Marriage Market

Which and how many attributes are relevant for the sorting of agents in a matching market? This paper addresses these questions by constructing indices of mutual attractiveness that aggregate information about agents’ attributes. The first k indices for agents on each side of the market provide the best approximation of the matching surplus by a k-dimensional model. The methodology is applied on a unique Dutch household survey containing information about education, height, body mass index, health, attitude toward risk, and personality traits of spouses.
Upper Cretaceous Planktonic Foraminifers and Biostratigraphy, Leg 120, Southern Kerguelen Plateau

Ocean Drilling Program Leg 120 Sites 747, and 750, and Hole 748C on the southern Kerguelen Plateau contain Cretaceous marine sections that span the upper Cenomanian-upper Maestrichtian. The most complete sections recovered from Sites 747 and 750 are Campanian and Maestrichtian. Older sections are fragmentary and only spot ages and paleotemperature indications can be determined. The section in Hole 748C lacks age-diagnostic planktonic species, and was deposited under very shallow marine conditions. Water temperature was temperate (perhaps in the Transitional Faunal Province in Sliter's sense) with keeled globotruncanids present through the Cenomanian-Santonian. Faunas in the upper Campanian and into the Abathomphalus mayaroensis Zone of the upper Maestrichtian, may be placed in the Austral Faunal Province. In the upper part of the A. mayaroensis Zone, temperatures were significantly higher with quite diverse globotruncanids and more complex biserial taxa at the location of Site 750. Waters at Site 750, to the south and east of Site 747, may have been warmer during the Upper Cretaceous, reflecting the presence of a counterclockwise gyre east of the Kerguelen Plateau.
International terrorism as a trade impediment

This article uses monthly data on bilateral trade in conjunction with monthly data on terrorism events and associated fatalities to shed light on the impact of terrorism on trade. Employing a structural model of trade, we provide evidence that, if at all, international terrorism displays effects on bilateral and multilateral trade only in the medium run (more than one and a half years after an attack/incident). The pure short-run impact of international terror on trade appears very small, if not negligible.
What is Worth Measuring ? What can it Tell us about Forages ?

and efficiency of utilization are characteristics of forages that determine animal performance, with variation in intake accounting for 60–90% of the variation in digestible energy (Mertens, 1994). It would therefore be desirable to measure those forage characteristics that relate most closely to intake and digestibility. Chemical fractions that have been associated with intake and digestibility include fibre, lignin and protein (Cherney and Mertens, 1998). A routine system of chemical characterization of forages for ruminants, then, must include determination of fibre, lignin and protein and critical to these is an accurate dry matter (DM) determination. Some characterizations, such as the determination of water-soluble carbohydrates (WSC), may be of particular importance in silage research. Others, such as tannin assays, starch and soluble fibres, may be of particular importance for some types of forages and some feeding situations. The worth of any particular assay, other than for fibre, lignin, and protein, is thus dependent on the researcher’s objectives and the likely economic impact of not performing the assay. If an antiquality factor limits production, it may become the most important factor to analyse for.
Modeling Pesticide Fate and Nonideal Transport From Seeds Treated with a Slow-Release Pesticide in a Laboratory Soil Column

This research evaluated the predictive ability of a pesticide fate and transport model to simulate the potential for pesticide leaching from slow-release insecticide-treated corn seeds. No studies in the literature report model evaluation for pesticide-treated seeds. The column studies consisted of ten 60 cm soil columns of silt loam soil, each planted with one corn seed treated with the active ingredient of an experimental pesticide. The columns were modeled using the Root Zone Water Quality Model (RZWQM), which is capable of simulating slow-release, instantaneous equilibrium (IE) and equilibrium kinetic (EK) sorption, and irreversible binding. The model was calibrated for hydrology (i.e., leachate from the bottom of the soil columns), crop growth, and total pesticide in the soil profile. Measured concentrations were compared to model predictions for IE and EK sorption scenarios across a range of sorption parameters derived from batch and time-dependent sorption studies. Modeling scenarios failed to predict the observed pesticide confinement (70% of applied pesticide) to primarily the upper 15 cm of the soil profile, with 1% to 20% of applied in the upper 15 cm for IE sorption and 3% to 18% of applied for EK sorption at the end of the simulation period. Both IE and EK sorption scenarios failed to predict pesticide in leachate (observed cumulative of 0.12% of applied) unless using minimum IE and EK sorption parameters. Model deviations from observations were hypothesized to be due to the model representing a theoretical two-dimensional process in one-dimension and the potential for preferential flow paths formed by root formation. Long-term (i.e., 20-year) simulations suggested that significant differences (i.e., average of 8% compared to less than 1% cumulative leaching) arise between IE and EK sorption after several plantings of the pesticide-treated seed. The error in assuming IE sorption for an EK sorption process is negligible over the short term but increases with subsequent chemical applications over the long term.
[677T mutation of the MTHFR gene in adenomas and colorectal cancer in a population sample from the Northeastern Mexico. Preliminary results].

INTRODUCTION Adequate intake of folates has been associated to low prevalence of colon cancer. Methylenetetrahydrofolate reductase enzyme (MTHFR) plays an important role in folate metabolism. The role of the 677 mutation at the MTHFR gene in the risk for colorectal cancer remains controversial. A recent report established that this mutation has a high prevalence in the healthy Mexican population. AIMS To analyze the prevalence of 677T MTHFR mutation in patients with colorectal cancer and controls without chronic gastrointestinal disorders. METHODS Seventy-four colorectal cancer, 32 adenomas and 110 normal samples were analyzed. Patients and controls were matched for sex and age. For each sample, DNA isolation, PCR, and mutation detection by restriction enzyme digestion were performed to determine the allele at the 677 position in the MTHFR gene. RESULTS Genotype 677C/677C was found in 18.7, 20.3, and 30.9% in adenomas, cancer lesions and controls, respectively. Frequencies of the 677C/677T genotype were 59.4, 56.7, and 47.3%, in adenomas, cancer lesions, and controls, respectively. Genotype 677T/677T was found in 21.9, 23.0, and 21.8% in adenomas, cancer lesions, and controls, respectively. The odds ratio between genotypes carrying the mutation (T/T and C/T) and normal genotype (CC) was 1.81 (IC 95% 0.97-3.3), chi 2 = 3.5, p = 0.06. CONCLUSION Our results showed that persons who carry the 677T mutation at MTHFR locus have a tendency for an increased risk for colorectal cancer. This study supports the basic concept that low levels of folic acid contribute with the colorectal cancer pathogenesis. Our lack of statistic significance may be due to reduced sample size.
Stability of Flame-Shock Coupling in Detonation Waves: 1D Dynamics

In the present study, we utilize spatially high-order convergence rate methods with complex reaction kinetics in resolving the nonlinear dynamics associated with one-dimensional unstable detonations. For a spark-induced detonation, as the detonation decays towards the self-sustaining Chapman–Jouguet mode from an over-driven mode, one obtains a sequence of physical oscillations between the flame and shock front, with different frequency ranges (categorized as high frequency-low amplitude and low frequency-high amplitude), dependent on the time after initiation of the detonation. The present studies indicate that one must use sufficient spatial resolution as well as realistic, complex kinetics to accurately simulate the preferred re-explosion and instability modes. Metrics that characterize the instabilities include, in addition to peak pressure, dominant high and low frequencies and time to re-explosion. A simple model for the transmission of acoustic and entropy waves is used to interpret physical phenomena creating the different instability modes, with reasonable quantitative correspondence to simulation results.
The Excitation of Lg Waves by Explosions: A Finite-Difference Investigation

Several mechanisms have been proposed to explain the excitation of the regional Lg phase by explosions. We examine some of these mechanisms with finite-difference simulations. An energy-flux technique is used to analyze the synthetic signals. The method is adapted from conventional array-analysis techniques and gives a clear characterization of wave-field intensity, wave slow- ness, and propagation direction. The vector energy flux in the model is studied instead of the scalar distribution of energy in the space-time domain. The cal- culations show that for an explosive source in a high P-wave velocity crust, P-wave energy cannot be effectively trapped in the crust, and the nongeomet- rical phase S* may be the primary contributor to theLg phase. For an explosive source buried in a low-velocity upper crust (i.e., where the P-wave velocity is lower than the upper-mantle S-wave velocity), part of the pS wave can be trapped in the crustal wave guide to form the Lg phase. The relative Lg excitation de- pends on the ratio between the P-wave velocity in the source region and the S-wave velocity in the uppermost mantle. Scattering effects can transfer P-wave or surface-wave energy into Lg, but the efficiency strongly depends on both the wave frequency and the characteristic size of the scatterers. Any source process that directly excites S waves is more efficient for generating Lg than the afore- mentioned mechanisms. Spall directly generates S-wave energy, and conse- quently is an efficient source for Lg. For actual explosions, all of these factors may simultaneously contribute to Lg excitation. Determining their relative im- portance and interactions requires additional observations.

INTERACTING GALAXIES IN THE A901/902 SUPERCLUSTER WITH STAGES

We present a study of galaxy mergers and the influence of environment in the Abell 901/902 supercluster at z∼ 0.165, based on 893 bright (RVega⩽ 24) intermediate-mass (M* ⩾ 109 M☉) galaxies. We use HST ACS F606W data from the Space Telescope A901/902 Galaxy Evolution Survey, COMBO-17, Spitzer 24 μm, and XMM-Newton X-ray data. Our analysis utilizes both a physically driven visual classification system and quantitative CAS parameters to identify systems which show evidence of a recent or ongoing merger of mass ratio >1/10 (i.e., major and minor mergers). Our results are (1) after visual classification and minimizing the contamination from false projection pairs, we find that the merger fraction fmerge is 0.023 ± 0.007. The estimated fractions of likely major mergers, likely minor mergers, and ambiguous cases are 0.01 ± 0.004, 0.006 ± 0.003, and 0.007 ± 0.003, respectively. (2) All the mergers lie outside the cluster core of radius R< 0.25 Mpc: the lack of mergers in the core is likely due to the large galaxy velocity dispersion in the core. The mergers, instead, populate the region (0.25 Mpc <R⩽ 2 Mpc) between the core and the cluster outskirt. In this region, the estimated frequency of mergers is similar to those seen at typical group overdensities in N-body simulations of accreting groups in the A901/902 clusters. This suggests the ongoing growth of the clusters via accretion of group and field galaxies. (3) We compare our observed merger fraction with those reported in other clusters and groups out to z∼ 0.4. Existing data points on the merger fraction for L ⩽ L* galaxies in clusters allow for a wide spectrum of scenarios, ranging from no evolution to evolution by a factor of ∼5 over z∼ 0.17–0.4. (4) In A901/902, the fraction of interacting galaxies, which lie on the blue cloud is 80% ± 18% (16/20) versus 34% ± 7% or (294/866) for non-interacting galaxies, implying that interacting galaxies are preferentially blue. (5) The average star formation rate (SFR), based on UV or a combination of UV+IR data, is enhanced by a factor of ∼1.5–2 in mergers compared to non-interacting galaxies. However, mergers in the A901/902 clusters contribute only a small fraction (between 10% and 15%) of the total SFR density, while the rest of the SFR density comes from non-interacting galaxies.
A productive system of early years professional development

This paper uses the concept of the productive system to identify some of the tensions between the stages of professional development of early years practitioners and the relationships between the various actors within the system of professional formation in England. In the context of the recommendations of the Nutbrown Review a series of challenges facing early years professionalism and the design and delivery of continuous professional development (CPD) are discussed. These include issues that relate to the predominance of external influence on the nature of early years professional knowledge, the significance of the early years setting in supporting practitioner learning and influences on workplace learning processes. Some strategies for strengthening practitioner influence over the productive system are briefly outlined, which relate specifically to how practitioners engage with the challenge of how CPD is organised and located as part of an early years professional identity.
Long-term renal survival in malignant hypertension

Background. Some studies have shown an improvement in the prognosis of patients with essential malignant hypertension (MHT), but data about long-term outcome and prognostic factors of these patients are scarce. Methods. We performed a single-centre retrospective analysis of 197 patients with MHT, diagnosed in the period 1974–2007. Results. Incidence of MHT remained stable along the different periods of the study. Renal damage at presentation was common (63% of patients) but renal function improved or remained stable after diagnosis in a majority of patients. The probability of renal survival was 84 and 72% after 5 and 10 years, respectively. Diagnosis during the first period (1974–85) of the study, previous chronic renal impairment, baseline renal function and proteinuria, 3266 R. González et al. © The Author 2010.

By multivariate analysis, mean proteinuria during follow-up remained as the only significant risk factor (OR, 2.72; 95% CI, 1.59–4.64). Renal survival for patients with mean proteinuria <0.5 g/24 h was 100 and 95% after 5 and 10 years, respectively. The number of patients who improved or stabilized their renal function significantly increased in the second and third periods of the study (1987–2007). Conclusions. Renal survival in MHT has improved in recent years. Mean proteinuria during follow-up is a fundamental prognostic factor for renal survival.
1 Fat mass and obesity associated ( FTO ) gene and hepatic 2 glucose and lipid metabolism 3

Common genetic variants of the fat mass and obesity associated (FTO) gene are strongly associated 9 with obesity and type 2 diabetes. FTO is ubiquitously expressed, but appears to have tissue-specific roles. 10 Earlier studies have focused on the role of hypothlamic FTO in the regulation of metabolism. However, it 11 appears that FTO plays a role in the regulation of metabolism in a tissue-specific manner. Recent studies 12 suggest that expression of hepatic FTO is regulated by metabolic signals such as nutrients and hormones and 13 altered FTO levels in liver affects glucose and lipid metabolism. This review outlines recent findings on 14 hepatic FTO in the regulation of metabolism, with particular focus on hepatic glucose and lipid metabolism. It 15 is proposed that abnormal activity of hepatic signaling pathways involving FTO links metabolic impairments 16 such as obesity, type 2 diabetes and nonalcoholic fatty liver disease (NAFLD). Therefore, a better 17 understanding of these pathways may lead to therapeutic approaches to treat these metabolic diseases by 18 targeting hepatic FTO. The overall goal of this review is to place FTO within the context of hepatic regulation 19 of metabolism. 20
