Learning strategies in excellent and average university students. Their evolution over the first year of the career
2012
The aim of this paper was to analyze the evolution of learning strategies of two groups of students, excellent and average, from 11 degrees of the UPV (Valencia/Spain) in their freshman year. We used the CEVEAPEU questionnaire. The results confirmed the availability of better strategies of excellent students and also the existence of evolutionary patterns in which affective-emotional strategies decrease, such as value of the task or internal attributions, and that others increase, such as extrinsic motivation and external attributions. It seems that the student does not meet your expectations in the new context and professors have important responsibilities. El objetivo de este trabajo era …
Investigations on the phosphoenolpyruvate carboxylase activity of spruce needles relative to the occurrence of novel forest decline
1991
Summary Investigations were carried out on phosphoenolpyruvate carboxylase (PEPC) activity in needles of Norway spruce trees [ Picea abies (L.) Karst.] at two natural sites during the course of three vegetation periods. PEPC activity found in needles of damaged trees was considerably higher than in needles of undamaged trees. Annual average figures varied up to 100%. The positive correlation between PEPC activity and the extent of damage of the investigated needles indicates a significant relationship between both parameters: the PEPC activity in spruce needles seems to be not only a qualitative, but also a quantitative indicator of the extent of damage. Higher PEPC activity in needles of d…
Turnover ratios and profitability ratios calculation methods: the book or average value
2019
The scientific literature of the turnover ratios and profitability ratios calculation offers to use book or average value of balance sheet calculation methods. Different schools of financial analysis nowadays offer many variations of the ratio calculations and even though the components of ratio formulas change, the meaning stays the same. The aim of this research is to analyze the turnover and profitability ratios, to study the different methods of calculation, based on different schools of financial analysis and empirical research results, and to create proposals for companies for the use of these methods for financial analysis. The authors of this paper are using the international scient…
Effect of the junction angle on turbulent flow at a hydraulic confluence
2018
Despite the existing knowledge concerning the hydrodynamic processes at river junctions, there is still a lack of information regarding the particular case of low width and discharge ratios, which are the typical conditions of mountain river confluences. Aiming at filling this gap, laboratory and numerical experiments were conducted, comparing the results with literature findings. Ten different confluences from 45 ∘ to 90 ∘ were simulated to study the effects of the junction angle on the flow structure, using a numerical code that solves the 3D Reynolds Averaged Navier-Stokes (RANS) equations with the k- ϵ turbulence closure model. The results showed that the higher the junction angle, the …

The castle's Hermitage of Yecla (Region of Murcia) constituted during the 13th to 16th centuries the first parish of the population, hosting a triptych-shaped altarpiece presided over by a tempera painting on wood of Our Lady of Humility or "Virgo Lactans", dated around 1370 and attributed to the painter Barnaba da Modena, which was the titular image of the mentioned temple under the title of Our Lady of the Incarnation, until at the end of the 18th century it changed ownership for the Conception of Our Lady. The table at averages of the eight hundred was placed in an a loft, appropriating it at the beginning of the 20th century by the retired military Pascual Spuche y Lacy, who sold it aro…
Models of the population playing the Rock-Paper-Scissors game
2018
We consider discrete dynamical systems coming from the models of evolution of populations playing rock - paper - scissors game . Asymptotic behaviour of trajectories of these systems is described, occurrence of the Neimark-Sacker bifurcation and nonexistence of time averages are proved.
Drivers of Competitiveness in European High-Tech Industries
2019
Our paper builds on the importance of high-tech manufacturing and knowledge-intensive services as significant competitiveness and economic growth drivers in the European Union and offers a fresh approach of the study on the competitiveness of secondary and tertiary high-tech industries across EU member states. Our analysis covers the 2008–2015 period and includes twelve old and new EU members. We opt for a balanced panel data approach in OLS and ARIMA frameworks to investigate the competitiveness of high-technology industries in the EU with the aim of uncovering the nature of the main explanatory factors behind their performance. Our results show that the number of persons employed and the …
Assessing the Beneficial Effects of Economic Growth: The Harmonic Growth Index
2011
In this paper we introduce the multidimensional notion of harmonic growth as a situation of diffused well-being associated to an increase of per capita GDP. We say that a country experienced a harmonic growth if during the observed period all the key indicators, proxies of the endogenous and exogenous forces driving population well-being, show a significantly common pattern with the income dynamics. The notion is operationalized via an index of time series harmony which follows the functional data analysis approach. This Harmonic Growth Index (HGI) is based on comparisons between the coefficients from cubic B-splines interpolation. Such indices are then synthesized in order to provide the g…
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…
Memory‐type control charts for censored reliability data
2023
Control charts are commonly used to monitor a process to detect undesirable changes. The main goal of this work is to propose exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) control charts to track a process by utilizing type-I censored generalized exponential (GE) distributed data. In particular, the censored data are replaced with the conditional expected value (CEV). A comparison between CUSUM and CUSUM ignoring unobserved covariates (CUSUM-IUC) charts is also a part of this study. The GE distribution is considered due to its application in reliability analysis. The performance of the charts is evaluated by using the average run length along with the standard devi…
