Is There a Correlation Between the Ease of Doing Business Index and the Haven Score?
2019
The importance of FDI is increasing in the last period, due to their impact on economic growth and development, creating new jobs, increasing productivity. So, many countries are trying to implement economic, financial and fiscal rules and procedures to attract as many foreign investors as possible. Gaps and mismatches between different tax systems are followed by multinational companies, in the spirit of erosion of the tax base and the existence of a lower tax burden. By analyzing the rankings regarding taxation and doing business published periodically by international bodies, a series of correlations can be identified between the indicators considered in order to make these rankings to d…
Valoración de los parámetros normales de ecocardiografía fetal en 2D y 3D a lo largo de la gestación
2015
La evaluación cardiaca fetal mediante ecografía forma parte de nuestra práctica clínica diaria. Por tanto, es muy importante disponer de valores de referencia para todos los parámetros cardiacos ajustados a nuestra población. Una forma de describir una medida de un parámetro cardiaco es mediante los Z score, que expresan cuántas desviaciones estándar está una observación por encima o debajo de la media esperada. Los Z score permiten normalizar el tamaño de las estructuras cardiacas respecto a algún parámetro de la biometría fetal, en vez de con la edad gestacional. Los Z-score son útiles para determinar si una estructura cardiaca mantiene su crecimiento respecto al crecimiento somático glob…
RAPD differentiation between Borderea pyrenaica and B. chouardii (Dioscoreaceae), two relict endangered taxa
2001
As currently circumscribed, the genus Borderea Mieg. comprises two narrowly distributed European taxa, Borderea pyrenaica (Bub.) Mieg. and B. chouardii (Gaussen) Heslot. An accumulation of facts such as that both species share a very close overall morphology, that only a single population of Borderea chouardii is known, and that they live in contrasting environments has led some authors to suggest that B. chouardii is a mere ecotype of the more widespread B. pyrenaica. We tested this hypothesis using RAPD markers in four populations of Borderea, three of them identified as B. pyrenaica and the other one representing the only known population of B. chouardii. Eleven out of twenty assayed pri…
Schizophrenia polygenic risk score and cannabis use modify psychosis expression in first episode psychosis patients and population controls
2019
AbstractBackgroundDiagnostic categories within the psychosis spectrum are widely used in clinical practice, however psychosis may occur on a continuum. Therefore, we explored whether the continuous distribution of psychotic symptoms across categories is a function of genetic as well as environmental risk factors, such as polygenic risk scores (PRSs) and cannabis use.MethodsAs part of the EU-GEI study, we genotyped first episode psychosis patients (FEP) and population controls, for whom transdiagnostic dimensions of psychotic symptoms or experiences were generated using item response bi-factor modelling. Linear regression was used, separately in patients and controls, to test the association…
The serum copper/zinc ratio in childhood and educational attainment : a population-based study
2016
Background Micronutrients are potentially important determinants of adult outcomes such as educational attainment. Copper and zinc have known effects on several medical conditions and cognitive development. Elevated copper and depressed zinc is a common trace metal imbalance. Methods We estimate the correlation between the copper/zinc ratio (Cu/Zn) in childhood (year 1980) and educational attainment in adulthood (year 2010). We use the Young Finns Study (YFS) combined with the Finnish Linked Employer-Employee Data (FLEED). The regression models account for confounders such as other biomarkers and parental observables. Results We report a sizeable, negative correlation between Cu/Zn and educ…
Does taking additional Maths classes in high school affect academic outcomes?
2023
Several studies in the mathematical education literature show the effect of students’ high school skills in maths on their success at higher levels of education and work. In particular, the importance of maths course taking in US high schools is highlighted to be important for college enrolment and completion. The choice of taking additional maths courses or, as in Italy, of choosing a high-school curriculum with more maths, is not random: it depends on several substantial factors such as gender and socio-economic status. This selection bias implies that the differences in the academic outcomes might be traceable not only to mathematics ability and knowledge. In this paper, the aim is to es…
Evaluating the impact of public subsidies on a firm's performance : a two-stage quasi-experimental approach
2009
In this paper we evaluate the effectiveness of regional R&D public programs in Catalonia (Spain) with a two-stage procedure. Firstly, we compare the performance of publicly subsidised companies (treated) with that of similar, but unsubsidised companies (non-treated). We use the Propensity Score Matching (PSM) methodology to construct a control group which, with regard to its observable characteristics, is as similar as possible to the treated group, and that allows us to identify firms which maintain the same propensity to receive public subsidies. Secondly, and once a valid comparison group has been established, we compare the respective performance of each firm using regression techniques…
A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
FINANCIAL RISKS – A CASE STUDY FOR AUTOMOTIVE INDUSTRY
2013
In general, financial risks – from operational risk to bankruptcy risk, are important distress for companies from every sector or industry. In this paper we try to measure the financial risk for the most important eight companies that activate in automotive industry. We propose a model in order to evaluate financial risk, by using discriminate analysis, which integrate five of the most important financial indicators: current ratio, return on investment, debt to equity, total assets turnover, working capital to total assets. Based on these results the rank will be very different beside the Global Fortune 500 rank that evaluates company only by the level of revenue.
The influence of Opuntia ficus-indica mucilage edible coating on the quality of ‘Hayward’ kiwifruit slices
2016
Abstract The aim of this work was to study the effect of mucilage edible coating extracted from Opuntia ficus-indica (OFI) on the quality and shelf life maintenance of packaged kiwifruit slices. OFI mucilage alone or added with TWEEN ® 20 were applied on kiwifruit fresh cut surfaces. After treatments, kiwifruit samples were stored under passive atmosphere at 5 ± 1 °C for 3, 5, 7 and 12 days. At each storage period, visual quality and flavor score, pectin content, ascorbic acid and the microbiological characteristics were measured together with CO 2 and O 2 content in the packages. Kiwifruit slices coated only with mucilage or with mucilage plus Tween 20, showed a significant higher firmness…
