National Dietetic Registration Examination: Perceptions of the Writing Experience
Authors: Lordly Daphne 
Published: May 2008

Purpose: Dietitians must pass the Canadian Dietetic Registration Examination (CDRE) to practise. Writers’ experiences with the exam were examined, along with factors associated with anxiety and coping mechanisms, preparation strategies, and if and how anxiety, coping, and preparation strategies are perceived to be related to exam performance.Methods: An exploratory descriptive methodology with a researcher-designed questionnaire was used to collect data from a purposive sample in 1999 and 2000 (n=54), and from a convenience sample in 2005 and 2006 (n=11). Participants were CDRE writers from Nova Scotia, New Brunswick, and Ontario.Results: Meaningful preparation was correlated with a more positive exam experience (p=0.023). Writers experiencing lower preparation anxiety were more confident they had passed (p=0.016). Successful coping strategies resulted in decreased writing anxiety (p=0.029). The 2005 to 2006 cohorts prepared less (p=0.004) and experienced less preparation anxiety (p=0.02). Five themes emerged, which extend our understanding of the exam-writing experience.Conclusions: Several strategies may positively influence writing anxiety and improve the overall writing experience. Individuals and organizations and/or writers can consider these findings as they engage in the exam process, revise and/or develop support material, give presentations, or provide advice.

Authors: Paradis Ann-Marie , Godin Gaston , Pérusse Louis , Vohl Marie-Claude 
Published: May 2008

Purpose: To compare dietary intakes of individuals with and without familial history of obesity (FHO) with recommendations from Canada’s Food Guide to Healthy Eating (CFGHE). Methods: This cross-sectional study recruited 197 women and 129 men with a body mass index of less than 30kg/m2 from the Quebec City metropolitan area. A dietitian obtained their dietary intakes, using a food frequency questionnaire. Results: Daily energy, macronutrient, and fibre intakes were not significantly different between individuals with and without FHO. No significant differences in the proportion of individuals who achieved the minimum CFGHE recommendations were observed between individuals with and without FHO. Conclusions: Findings of our study suggest that individuals with and without FHO have comparable dietary intakes when compared to Canadian dietary guidelines.
A fracture-entrainment model for snow avalanches
Authors: Cherepanov Genady P. , Esparragoza Ivan E. 
Published: May 2008

AbstractWe use the invariant Γ integral of fracture mechanics to calculate the frontal pressure and resistance to the downward motion a of snow avalanche. A basic characteristic property of the snowpack, termed the entrainment toughness, is introduced. From an analysis of the non-entrainment frictional mechanisms of avalanches, we find the necessary condition for a fracture-entrainment regime, and from an analysis of limiting equilibrium of gravitational force and frontal resistance, the necessary condition equation for the start of avalanches. We then derive the governing equations for the dynamics of avalanches, using a point-mass approach with entrainment taken into account. The governing equations are used to numerically simulate the Vallée de la Sionne (Switzerland) avalanche of 7 February 2003.
Glacier-bed characteristics of midtre Lovénbreen, Svalbard, from high-resolution seismic and radar surveying
Authors: King E.C. , Smith A.M. , Murray T. , Stuart G.W. 
Published: May 2008

AbstractWe conducted a seismic and radar survey of the central part of midtre Lovénbreen, a small, polythermal valley glacier in Svalbard. We determined the physical properties of the material beneath the glacier by measuring the reflection coefficient of the bed by comparing the energy of the primary and multiple reflections, and deriving the acoustic impedance. By making reasonable assumptions about the properties of the basal ice, we determined the acoustic impedance of the bed material as (6.78 ± 1.53) × 106 kg m−2 s−1. We interpret the material beneath the glacier to be permafrost with up to 50% ice, and we speculate that the material may be frozen talus similar to a deposit observed directly by others beneath another Svalbard glacier. The implication for midtre Lovénbreen is that the basal material beneath the present glacier is not able to support fast flow. We conclude that midtre Lovénbreen has most likely had limited capability for faster flow in the past, with motion dominated by internal deformation. Midtre Lovénbreen is used as a ‘study glacier’ for the scientific community in Svalbard, and a large number of studies have been based there. Our results show that it cannot be used as an analogue for larger glaciers in Svalbard, having distinct basal boundary conditions.

AbstractVariability in antidepressant response is due to genetic and environmental factors. Among genetic factors, the ones controlling for availability of the drug at the target site are interesting candidates. Rs6295C/G SNP in the 5‐HT1A gene (HTR1A) has been found to affect the expression and function of HTR1A. In fact rs6295C/G is in strong linkage disequilibrium with other polymorphisms of HTR1A suggesting that those functional effects could be associated with polymorphisms other than or together with the synonymous rs6295C/G. In the present study we examined the possible association of a panel of markers in strong linkage disequilibrium of the HTR1A with SSRI/SNRI response in 137 Japanese major depression subjects followed for 6 weeks. We observed a significant association of better response to antidepressant in rs10042486C/C (P < 0.0001), rs6295G/G (P < 0.0001) and rs1364043T/T (P = 0.018) genotype carriers (minor allele homozygotes), independently from clinical variables. Furthermore minor allele homozygous carriers in all these three SNPs were associated with treatment response by various assessment such as HAM‐D score change over time (P = 0.001), week 2 (P < 0.0001), 4 (P = 0.007), and 6 (P = 0.048) as well as response rate (P = 0.0005) and remission rate (P = 0.004). We also pointed out the genotyping mis‐definition of rs6295C/G in the previous four articles. In conclusion, this is the first study that reports a significant association of antidepressant response with rs10042486C/T and rs1364043T/G variants of HTR1A and also with rs10042486–rs6295–rs1364043 combination. This finding adds an important information for the pathway of detecting the genetics of antidepressant response even if results must be verified on larger samples. © 2008 Wiley‐Liss, Inc.

AbstractDispositional coping styles are important moderators of the stress reaction and are altered in stress‐related disorders like cardiovascular diseases and affective disorders. Heritability studies suggest a considerable genetic contribution to the interindividual variability in coping styles. Since the angiotensin‐converting enzyme (ACE) gene has been described to be associated with the vulnerability for stress‐related disorders and with altered stress hormone regulation, we investigated the ACE gene as potential candidate gene for coping styles. Five hundred forty one mentally healthy subjects and 194 patients suffering from depression participating in the Munich Antidepressant Response Signature (MARS) project were examined. Coping styles were assessed with a self‐report questionnaire (German Stress Coping Questionnaire SVF78) measuring the individual coping style pattern in response to stressful situations. We genotyped 15 single nucleotide polymorphisms (SNPs) and the insertion/Deletion (I/D)‐polymorphism in the ACE gene region and investigated their associations with coping styles. In healthy subjects, the highest association was observed between rs8066276, an intronic SNP of the ACE gene, and the coping factor Distraction. A further intronic SNP rs4305, not in linkage disequilibrium with rs8066276, showed an association with Devaluation/Defense. All associated copying styles can be categorized as potentially stress reducing factors (positive coping). Both SNPs were also found to be associated with positive coping styles in the patient sample; rs8066276 was associated with Devaluation/Defense, and rs4305 showed associations with Control. These results suggest that the ACE gene is involved in the development of coping strategies. © 2008 Wiley‐Liss, Inc.
Hydrogen Abstraction and Electron Transfer with Aminoxyl Radicals: Synthetic and Mechanistic Issues
Authors: Galli Carlo , Gentili Patrizia , Lanzalunga Osvaldo 
Published: May 2008

AbstractAminoxyl radicals (R2NO.) are a valuable class of reactive intermediates with interesting synthetic and reactivity properties. This Minireview summarizes salient synthetic results obtained in radical oxidations using aminoxyl radicals, and then focuses on reactivity issues arising from recent literature surveys. The structural and reactivity features of the aminoxyl radical and substrate provides a possible explanation of the double reactivity of the aminoxyl radicals. This mechanistic dichotomy between H‐atom abstraction and electron‐abstraction routes is highlighted in this Minireview.

AbstractBACKGROUND: The prevalence of NTDs in the US declined significantly after mandatory folic acid fortification; however, it is not known if the prevalence of NTDs has continued to decrease in recent years relative to the period immediately following the fortification mandate. METHODS: Population‐based data from 21 birth defects surveillance systems were used to examine trends in the birth prevalence of spina bifida and anencephaly during 1999–2000, 2001–2002, and 2003–2004. Prevalence data were stratified by non‐Hispanic White, non‐Hispanic Black, and Hispanic race or ethnicity. Prevalence ratios were calculated by dividing the birth prevalences during the later time periods (2001–2002 and 2003–2004) by the birth prevalences during 1999–2000. RESULTS: During 1999–2004, 3,311 cases of spina bifida and 2,116 cases of anencephaly were reported. Hispanic infants had the highest prevalences of NTDs for all years. For all infants, the combined birth prevalences of spina bifida and anencephaly decreased 10% from the 1999–2000 period to the 2003–2004 period. The decline in spina bifida (3%) was not significant; however the decline in anencephaly (20%) was statistically significant. CONCLUSIONS: While the prevalences of spina bifida and anencephaly in the United States have declined since folic acid fortification in the food supply began, these data suggest that reductions in the prevalence of anencephaly continued during 2001–2004 and that racial and ethnic and other disparities remain.

Residual Pattern Based Test for Interactions in Two‐Way ANOVA
Authors: Ning Wei , Kim Hyune‐Ju 
Published: May 2008

AbstractThis article proposes a new test to detect interactions in replicated two‐way ANOVA models, more powerful than the classical F ‐test and more general than the test of Terbeck and Davies (1998, Annals of Statistics 26, 1279–1305) developed for the case with unconditionally identifiable interaction pattern. We use the parameterization without the conventional restrictions on the interaction terms and base our test on the maximum of the standardized disturbance estimates. We show that our test is unbiased and consistent, and discuss how to estimate the p ‐value of the test. In a 3 × 3 case, which is our main focus in this article, the exact p ‐value can be computed by using four‐dimensional integrations. For a general I × J case which requires an (I – 1) × (J – 1) dimensional integration for a numerical evaluation of the exact p ‐value, we propose to use an improved Bonferroni inequality to estimate an upperbound of the p ‐value and simulations indicate a reasonable accuracy of the upperbound. Via simulations, we show that our test is more powerful than the classical F ‐test and also that it can deal with both situations: unconditionally identifiable and non‐unconditionally identifiable cases. An application to genetic data is presented in which the new test is significant, while the classical F ‐test failed to detect interactions. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Simultaneous Inference in General Parametric Models
Authors: Hothorn Torsten , Bretz Frank , Westfall Peter 
Published: May 2008

AbstractSimultaneous inference is a common problem in many areas of application. If multiple null hypotheses are tested simultaneously, the probability of rejecting erroneously at least one of them increases beyond the pre‐specified significance level. Simultaneous inference procedures have to be used which adjust for multiplicity and thus control the overall type I error rate. In this paper we describe simultaneous inference procedures in general parametric models, where the experimental questions are specified through a linear combination of elemental model parameters. The framework described here is quite general and extends the canonical theory of multiple comparison procedures in ANOVA models to linear regression problems, generalized linear models, linear mixed effects models, the Cox model, robust linear models, etc. Several examples using a variety of different statistical models illustrate the breadth of the results. For the analyses we use the R add‐on package multcomp, which provides a convenient interface to the general approach adopted here. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Preparation of Highly Active and Dispersed Platinum Nanoparticles on Mesoporous Al‐MCM‐48 and Their Activity in the Hydroisomerisation of n‐Octane
Authors: Campelo Juan M. , Lee Adam F. , Luque Rafael , Luna Diego , Marinas Jose M. , Romero Antonio A. 
Published: May 2008

AbstractPlatinum nanoparticles supported on Al‐MCM‐48 materials have been prepared. The resultant catalysts have been characterized by means of XRD, N2 physisorption experiments, scanning electron microscopy (SEM), transmission electron microscopy (TEM), temperature‐programmed reduction (TPR), and diffuse reflectance infrared Fourier‐transform spectroscopy (DRIFTS). The activity of these nanoparticles has been tested in relation to the hydroisomerisation of n‐octane. The catalytic activities were typically 50 %, with selectivities in the isomerisation process in excess of 70 %, favouring the formation of the 3‐methylheptane isomer with respect to the 2‐ and 4‐methylheptanes.

Published: May 2008

AbstractThe interactions of simple carbohydrates with aromatic moieties have been investigated experimentally by NMR spectroscopy. The analysis of the changes in the chemical shifts of the sugar proton signals induced upon addition of aromatic entities has been interpreted in terms of interaction geometries. Phenol and aromatic amino acids (phenylalanine, tyrosine, tryptophan) have been used. The observed sugar–aromatic interactions depend on the chemical nature of the sugar, and thus on the stereochemistries of the different carbon atoms, and also on the solvent. A preliminary study of the solvation state of a model monosaccharide (methyl β‐galactopyranoside) in aqueous solution, both alone and in the presence of benzene and phenol, has also been carried out by monitoring of intermolecular homonuclear solvent–sugar and aromatic–sugar NOEs. These experimental results have been compared with those obtained by density functional theory methods and molecular mechanics calculations.
