Accuracy of Folksam Electronic Crash Recorder (ECR) In Frontal and Side Impact Crashes

Estimation of crash severity from crash recorders is important in the evaluations of vehicle crashworthiness. The number of cars fitted with on-board crash recorders is in creasing. The majority of these recorders are integrated with airbag sensors that usually have limitations regarding e.g. recording time and sampling rate. The aim with this study was to evaluate the accuracy of an Electronic Crash Recorder (ECR) compared to laboratory accelerometers. The ECR records car body acceleration during a crash event. The ECR is part of a large accident data collection system where 10,000 units per year are installed in various car models in Sweden. The ECR has the possibility to record acceleration in longitudinal and lateral impacts and also in multiple events. The ECR also meet requirements like recording data 30 ms prior to pulse start (tₒ) and recording time up to 500 ms with 1 kHz sampling rate. The focus was to evaluate the accuracy in a wide range of impact speeds and with different pulse shapes. A series of 12 sled tests were conducted with delta-V between 12.3 and 73.5 km/h. In each test the sled was fitted with 10 ECRs as well as a laboratory accelerometer. Five ECRs were fitted in the longitudinal direction and five in the lateral. In total 120 ECR recordings were evaluated. Acceleration data were filtered according to CFC60 as defined in SAE J211. Change of velocity, mean and peak accelerations were derived from the filtered acceleration. No systematic error was found regarding delta-V. The systematic error of mean acceleration in the longitudinal direction was 0.4 g (3.5%). For all tests the standard deviation for delta-V in the longitudinal direction was 0.8 km/h (1.9%). The corresponding value for the lateral direction was 1.4 km/h (3.9%). The standard deviation for mean acceleration was 0.2 g (1.7%) in the longitudinal direction and 0.4 g (3.0%) in the lateral direction. In general no major differences in standard deviation between low and high speed crash tests were found. Overall the evaluation of the ECR showed that a low cost accelerometer device gives accuracy close to a laboratory accelerometer.
Enhancing customer service: Perspective taking in a call centre

We propose that an important prerequisite of helping customers is the capacity to take the customer's perspective. If this is the case, then it is also important to consider the factors that might facilitate perspective taking. To investigate this, 347 customer service agents in a UK call centre were surveyed on the antecedents and outcomes of customer-oriented perspective taking. Managers also supplied ratings of helping behaviour for 141 of the service agents. Structural equation modelling showed a positive relationship between perspective taking and self-reported helping, and this relationship was partially mediated by empathy. Perspective taking was also positively related to managers' ratings of helping but this relationship was not mediated by empathy. In turn, service agents' perspective taking was predicted by the perceived reciprocity of customers and by having a positive customer role orientation (which was itself predicted by job enrichment). Predictors of helping customers included perspective taking, empathy, and having an integrated understanding of the call centre's services. Enhancing employees' perspective taking and their integrated understanding of the organization's services might thus be hitherto neglected avenues for enhancing the quality of customer service.
Relationships among growth curve parameters, weights and reproductive traits in Guzera beef cows.

H.N. Oliveira*. R.B. Lobo and C.S. Pereira FMVZ-UNESP Depto. Melhoramento e Nutrifao Animal BOTUCATU(SP). FMRP-USP Depto. Genetica Ribeirao Preto(SP) EV-UFMG Depto. Zootecnia Belo Horizonte(MG) Brazil SUMMARY Von Bertalanffy nonlinear model was used to fit weight-age data for 575 females Guzera (Zebu beef cattle) reared under range conditions in southeastern Brazil, to obtain estimates of h2 and genetic and phenotypic correlation for the relevant growth curve parameters, weights from 240 to 730 days of age and reproductive traits. The (co)variance components were obtained by REML fitting univariate and bivariate animal models. The h2 estimates in univariate analyses for growth curve parameters A and k were 0.63 and 0.08 respectively, and agreed closely with those of the various bivariate analyses. Genetic and phenotypic correlation between A and k were high and negative. Genetic correlations between observed weights and A and k indicated that selection for weight will reduce maturation rate and improve mature weight, although, phenotypically, heavier animals on ages considered were also early maturing. Correlations among parameters A and k and reproductive traits indicated that heavier and late maturing cows were also sexually late maturing.
TITLE: Genetic Counseling for Breast Cancer Susceptibility in African American Women

Purpose: This study evaluated rates of BRCA1 and BRCA2 (BRCA1/2) test result acceptance among African American women and identified determinants of test result acceptance. Methods: Acceptance of BRCA1/2 test results was evaluated among 157 African American women at high and moderate risk for having a BRCA1/2 mutation who were offered genetic testing as part of a clinical genetic counseling research program. Results: Twenty-two percent of women received BRCA1/2 test results. Test result acceptance differed between women with a ≥10% prior probability of having a BRCA1/2 mutation (34%) and those who had a 5% prior probability (8%). Among women with a ≥10% prior probability, test result acceptors were most likely to be married (OR=5.29, 95% CI=1.82, 15.38, p=.002) and be less certain about their risk of developing cancer (OR=3.18, 95% CI=1.04, 9.80, p=.04). Conclusion: These results demonstrate that acceptance of BRCA1/2 test results may be limited among African American women. Being married and having less certainty about one’s cancer risk may motivate acceptance of BRCA1/2 test results among African American women. It may be important to emphasize the possibility that BRCA1/2 test results may not clarify cancer risks during pre-test counseling with African American women to ensure informed decision-making
Graft survival of en bloc versus single kidney transplantation from small pediatric donors: a meta-analysis with trial sequential analysis

Background: Although renal transplantation from small pediatric donors can relieve the pressure of the shortage of organs, the graft survival differs among different studies. We conducted this meta-analysis to evaluate the prognosis of patients receiving en bloc versus single allograft from small pediatric donors. Methods: A systematic search in PubMed, Embase, and web of science was performed to identify relevant studies. Individual hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) were combined to calculate the prognostic value. A cumulative meta-analysis based on publication year was also conducted. Trial sequential analysis (TSA) was performed to estimate the quantity of the evidence. Results: Seven studies consisting of 4,284 cases were included, and risk estimates from six of these studies were finally pooled for quantitative analysis. We found that compared with single kidney transplantation from small pediatric donors, en bloc kidney transplant suggested a better graft outcome of recipients (HR=0.57, 95% CI: 0.49–0.67). The findings in the current study were based on sufficient evidence by TSA. Furthermore, no evidence of publication bias in the meta-analysis was noted. Conclusions: En bloc kidney transplantation from small pediatric donors was significantly associated with a superior graft survival when compared with single kidney transplant.
Simplicial presheaves of coalgebras

The category of simplicial R-coalgebras over a presheaf of commutative unital rings on a small Grothendieck site is endowed with a left proper, simplicial, cofibrantly generated model category structure where the weak equivalences are the local weak equivalences of the underlying simplicial presheaves. This model category is naturally linked to the R-local homotopy theory of simplicial presheaves and the homotopy theory of simplicial R-modules by Quillen adjunctions. We study the comparison with the R-local homotopy category of simplicial presheaves in the special case where R is a presheaf of algebraically closed (or perfect) fields. If R is a presheaf of algebraically closed fields, we show that the R-local homotopy category of simplicial presheaves embeds fully faithfully in the homotopy category of simplicial R-coalgebras.
Assessment of Large Gut Obstruction in Rural setup

Introduction: Large bowel Obstruction is a widespread, emergent condition, which requires early identification, meticulous work up and prompt surgical intervention, wherever indicated. Materials and Methods: 25 consecutive patients of all age groups (excluding pediatric age group) presenting with large bowel obstruction, who had been admitted in Dhiraj Hospital, between May 2010 to September 2013, were selected randomly. Results and Discussion: Present study revealed highest number of cases of large bowel obstruction occurring in age-group 51-60 years (9 years- 36%). In our study, no significant difference had been noted with respect to age & sex related incidence and distribution of large bowel obstruction. In this study, colorectal malignancy was found to be the biggest contributors of large bowel obstruction with nearly half the cases attributed to it (13 cases- 52%).
EXPLORING PHENOTYPIC FLORAL INTEGRATION IN IRIS PUMILA

The angiosperm flower is a complex integrated phenotype, but within this structure there are partly independent units or modules. The interconnections among floral organ traits are hypothesized to be mostly generated by pollinatormediated selection. In this study, we explore whether floral dry mass per area (DMA) in an insect-pollinated herb, Iris pumila, exhibits a modular correlation pattern as has been reported for some size-related traits. We found that the overall pattern of floral organ integration with regard to DMA was uneven in the offspring of Iris pumila derived from a sunexposed and a shaded natural population. Since principal component analysis (PCA) showed that most of the eigenvalue variance was explained by the first two principal components (PCs), these PCs were considered as two floral modules. The greatest factor loadings on the first PC axis was that of the perianth and style arm DMA (PSDMA) and perianth tube DMA (PTDMA),while on the second PC axis, the greatest factor loading was that of stamen DMA (STDMA). The results indicate that the function of the first module would be to attract a pollinating vector, while the second one would reflect male functions. Selection analyses revealed that the targets of phenotypic selection were both intra-floral integration and individual floral traits. Both PSDMA and PC1DMA were under strong linear selection, while PTDMA experienced direct stabilization selection. The level of integration in floral organ DMA expressed in the term of relative eigenvalue variance appeared to be rather low, as was documented for other angiosperm taxa.
Arctic moisture source for Eurasian snow cover variations in autumn

Eurasian fall snow cover changes have been suggested as a driver for changes in the Arctic Oscillation and might provide a link between sea-ice decline in the Arctic during summer and atmospheric circulation in the following winter. However, the mechanism connecting snow cover in Eurasia to sea-ice decline in autumn is still under debate. Our analysis is based on snow observations from 820 Russian land stations, moisture transport using a Lagrangian approach derived from meteorological re-analyses. We show that declining sea-ice in the Barents and Kara Seas (BKS) acts as moisture source for the enhanced Western Siberian snow depth as a result of changed tropospheric moisture transport. Transient disturbances enter the continent from the BKS region related to anomalies in the planetary wave pattern and move southward along the Ural mountains where they merge into the extension of the Mediterranean storm track.
Effect of Sisal Fiber Surface Treatment on Properties of Sisal Fiber Reinforced Polylactide Composites

Mechanical properties of composites are strongly influenced by the quality of the fiber/matrix interface. The objective of this study was to evaluate the mechanical properties of polylactide (PLA) composites as a function of modification of sisal fiber with two different macromolecular coupling agents. Sisal fiber reinforced polylactide composites were prepared by injection molding, and the properties of composites were studied by static/dynamic mechanical analysis (DMA). The results from mechanical testing revealed that surface-treated sisal fiber reinforced composite offered superior mechanical properties compared to untreated fiber reinforced polylactide composite, which indicated that better adhesion between sisal fiber and PLA matrix was achieved. Scanning electron microscopy (SEM) investigations also showed that surface modifications improved the adhesion of the sisal fiber/polylactide matrix.
The Agricultural Competitiveness of the Alqueva Irrigation Project under the 2003 CAP Reform and the Health Check

The main purpose of this paper is to assess the competitiveness of the Alqueva irri gation project in the Alentejo region, southern Portugal. This project will create 110 thousand hectares of irrigated land in the region. The latest developments of Com mon Agricultural Policy in 2003 and 2009 and the Water Framework Directive guidelines could have negative impacts on the project competitiveness. The selec tion of representative farms was made using farmers’ interviews and multivariate methods. A multi-period mathematical programming model was developed to as sess the farms competitiveness. The results show that the Common Agricultural Pol icy and the Water Framework Directive will have negative effects on farms. This can be overcome by the adoption of new technologies and more sustainable a gri cultural systems ensuring the future competitiveness of irrigated farms.
Determinants of Health in Belarus: Evidence from the "Income and Expenditures of Households" Survey

Unprecedented mortality growth emerged in the early 1990’s in the countries of the former USSR has been extensively documented. It has been widely recognized that the consequences of the socio-economic crisis had a negative impact on health. Nowadays, there is a vast amount of literature about the health crisis in Russia whereas other countries of the former USSR such as Belarus have received little if any attention. Meanwhile, the notable divergence in recent mortality trends among the former Soviet republics suggests that the health crisis in these countries may not necessary mirror that in Russia. Therefore, investigating health and its determinants in Belarus appears to be a valuable contribution towards understanding of the nature of the health crisis in the whole region. On the basis of data from the “Income and Expenditures of Households” Survey conducted in Belarus annually our study aims at exploring the recent trends in health and estimating the impact of a number of demographic, socioeconomic and lifestyle variables on health at individual level. Given the wellestablished relationship between self-rated health and mortality, our findings facilitate further research on mortality determinants in Belarus.
The moderating effects of innovativeness on new product development ability

Apesar do numero de publicacoes especificas sobre Orientacao para Aprendizagem e para Mercado, nao ha consenso sobre a relacao entre estes construtos e Inovacao (IN). Neste sentido, este estudo investiga o impacto da Orientacao para Aprendizagem e para Mercado na Habilidade de Desenvolvimento de Novos Produtos (HDNP) em contextos de alta e baixa orientacao para Inovacao. A populacao alvo foi um grupo de empresas brasileiras com mais de 30 empregados. Os dados foram analisados atraves de uma analise de regressao hierarquica. Os resultados indicam um impacto significativo e negativo da interacao Orientacao para Mercado x Capacidade de Inovacao na HDNP. Ja a interacao Orientacao para Aprendizado x Capacidade de Inovacao apresentou um efeito significativo e positivo sobre HDNP. Portanto, em ambientes de negocios com alto nivel Inovacao, a Orientacao para Aprendizagem excede a importância da Orientacao para Mercado no desenvolvimento de novos produtos. Quando o nivel de Inovacao das empresas e baixa, porem, a HDNP tende a tirar proveito da Orientacao para Mercado, em vez de Orientacao para Aprendizagem.
Feeding Patterns of Greenland halibut (Reinhardtius hippoglossoides) in Flemish Pass (Northwest Atlantic)

A quali tat ive study of the food composit ion of Greenland halibut (Reinhardtius hippoglossoides) was made by on-board analysis of commercially caught fish in 1992. The fish were caught east of Newfoundland (NAFO Div. 3LM) in unusually deep waters, with an average of 1 040 m. Variations in feeding according to predator size, depth and month were studied. The annual average percentage of empty stomachs was 69%, increasing through the year for specimens over 60 cm. The frequency of occurrence (FO) of food items was used to evaluate the importance of prey groups. Fish (39%), cephalopods (32%) and decapod crustaceans (22%) were the main items, with cannibalism reaching 2%. An abrupt change in diet composition occurred in fish between 60 and 69 cm, from feeding on decapod crustaceans and cephalopods to fish and factory ship discarded offal. The influence of the fishery itself on the diet of Greenland halibut was observed when an important food component in the largest specimens (>60 cm) consisted of offal discarded after fish processing. This study indicates that the FO of the main prey groups bears more relation to the size of fish than with depth.
Structural transformation of Portuguese exports and the role of foreign-owned firms: A descriptive analysis for the period 1995-2005

In this paper we use a recent measure of the “income level of a country’s exports” proposed by Hausmann et al. (2007) to characterize the structure of the Portuguese export basket, its recent evolution and the role of foreign-owned firms in this process. We find that between 1995 and 2005 the improvement in the “income content” of the Portuguese export basket relative to the world average was achieved through an above-average “structural transformation effect” that more than offset a bellow-average effect of having a significant share of products exposed to an increasing competition from emerging economies. We find that the weight of exports with “high” and “very high income content increased considerably in this period, with these two classes explaining more than one half of the total export growth. Analysing the presence of foreign-owned firms in different industries, we find a higher than average share of foreign affiliated firms in products with “High” and “Very High” income content. These and other pieces of evidence suggest that foreign-owned firms have played a relevant role both in the growth of Portuguese exports and in the increase of their income content.
The Role of Social Support in Prediction of Stress During Pregnancy

BACKGROUND AND OBJECTIVE: Stress and lack of social support during pregnancy are associated with adverse consequences such as miscarriage, nausea, vomiting, preeclampsia, preterm delivery, low birth weight and different types of mental illnesses. This study, therefore, aimed to determine the role of social support in prediction of stress during pregnancy. METHODS: This cross-sectional study was performed on 210 pregnant women aging 18-40 years, who referred to two teaching hospitals of Babol in 2013. The subjects filled out demographic profile checklist, Pregnancy Experience Scale (PES) and Social Support Questionnaire (SSQ) in the first, second and third trimesters of pregnancy. The data were analyzed. FINDINGS: The mean score of social support in the pregnant women was 12.87±4.18 (range: 0-25). The highest level of social support in the three trimesters of pregnancy was received from family. The mean overall support in the first trimester was significantly higher than the second and third trimesters (4.50±13.48 vs. 3.83±12.25 and 4.06±12.87, respectively) (p<0.05). Approximately a third of women had experienced stress during pregnancy. Most of the unpleasant experiences occurred in the third trimester of pregnancy. The obtained results demonstrated that social support had a significant positive relationship with pleasant experiences and a significant negative relationship with unpleasant experiences and stress during pregnancy. Social support predicted 50% of the variance in stress scores during pregnancy. The strongest negative predictor of stress during pregnancy was family support (β= -0.470) followed by support from friends and neighbors, and subjects’ perception of support (p<0.05). CONCLUSION: Considering the negative relationship between stress during pregnancy and support from family, friends, and neighbors, women’s health care professionals should implement effective strategies to promote the level of social support during pregnancy.
BRUNO: A Deep Recurrent Model for Exchangeable Data

We present a novel model architecture which leverages deep learning tools to perform exact Bayesian inference on sets of high dimensional, complex observations. Our model is provably exchangeable, meaning that the joint distribution over observations is invariant under permutation: this property lies at the heart of Bayesian inference. The model does not require variational approximations to train, and new samples can be generated conditional on previous samples, with cost linear in the size of the conditioning set. The advantages of our architecture are demonstrated on learning tasks that require generalisation from short observed sequences while modelling sequence variability, such as conditional image generation, few-shot learning, and anomaly detection.
Surface Roughness Measurements on Gas Turbine Blades

Results are presented from profilometer measurements of the surface roughness on inservice turbine engine blades from F-100 and TF-39 aeroengines. On each blade, one roughness profile is taken in the region of the leading edge, the mid-chord and the trailing edge on both the pressure and suction sides for a total of 6 profiles. Thirty 1st stage turbine blades are measured from each engine. Statistical computations are performed on these profiles and the root mean square height, skewness and kurtosis of the roughness height distribution are presented along with the correlation length of the autocorrelation function.The purpose of this work is to provide insight into the nature of surface roughness characteristics of inservice turbine blades which can be used in the development of scaled laboratory experiments of boundary layer flow and heat transfer on turbine engine blades.Copyright © 1989 by ASME
