Business Models and Economic Approaches for Recovering Energy from Wastewater and Fecal Sludge
2015
Universal access to water, sanitation and energy services are key challenges in low income countries. The conventional model of providing water, sanitation and waste disposal as a social service is no longer viable because national authorities lack financial and human resources for operation and maintenance and for addressing the sanitation needs locally. Human excreta and wastewater represent resources that can be used to generate new income and support livelihoods through use as a source of energy. The reduction, removal and reuse of wastes must become financially feasible and economically profitable and yield high returns. This requires innovative and sustainable business models and fina…
Energy Efficient Resource Allocation for Wireless Power Transfer Enabled Collaborative Mobile Clouds
2016
In order to fully enjoy high rate broadband multimedia services, prolonging the battery lifetime of user equipment is critical for mobile users, especially for smartphone users. In this paper, the problem of distributing cellular data via a wireless power transfer enabled collaborative mobile cloud (WeCMC) in an energy efficient manner is investigated. WeCMC is formed by a group of users who have both functionalities of information decoding and energy harvesting, and are interested for cooperating in downloading content from the operators. Through device-to-device communications, the users inside WeCMC are able to cooperate during the downloading procedure and offload data from the base sta…
Do school resources increase school quality ?
2010
The aim of this paper is to verify whether school resource factors have an impact on the quality of education. This latter is measured with the help of a unique database on student scores in international skills tests. The general difficulties inherent in this type of study are the possibility of endogeneity bias and measurement errors. After estimation bias correction, we show that improvement in the quality of educational systems does not necessarily require an increase in school resources. When an alternative indicator of the performance of educational systems is used, our results are confirmed. Consequently, one should remain cautious about recommending purely financial measures to impr…
TEACHERS’ READINESS TO IMPLEMENT THE ACQUISITION OF TRANSVERSAL SKILLS IN THE CONTEXT OF THE NEW STANDARD
2019
In today’s rapidly changing world, when information technologies are developing very fast, a new change of the paradigm of the educational system is needed. It means that a teacher’s pedagogical activities also have to change – from an educator to a cooperation partner in the teaching/learning process. National Centre for Education (NCE) has worked out a new ”Competence approach to teaching/learning content”, the aim of which is to ensure the acquisition of the content of general education based on competence approach, and which embraces all stages in education.The objective of the article is to reveal the essence of competence approach and the readiness of primary school teachers to imple…
The Impact of Inattention, Hyperactivity/Impulsivity Symptoms, and Executive Functions on Learning Behaviors of Children with ADHD
2017
Children diagnosed with attention deficit/hyperactivity disorder (ADHD) are at risk of experiencing lower academic achievement compared to their peers without ADHD. However, we have a limited understanding of the mechanisms underlying this association. Both the symptoms of the disorder and the executive functions can negatively influence learning behaviors, including motivation, attitude toward learning, or persistence, key aspects of the learning process. The first objective of this study was to compare different components of learning behaviors in children diagnosed with ADHD and typically developing (TD) children. The second objective was to analyze the relationships among learning behav…
A Performance-Based Test for Assessing Students’ Online Inquiry Competences in Schools
2018
In this paper, we introduce a performance-based test for measuring adolescents’ competences in online inquiry. The test covers four competence dimensions: (1) searching and selecting relevant sources, (2) identifying the main ideas presented in the sources, (3) evaluating the credibility of the sources, and (4) synthesizing information across the sources. We implement a technological solution called NEURONE to carry out this routine. The scoring of the test data is demonstrated by presenting preliminary results of a case study. Finally, we discuss the strengths and limitations of the test.
On Infiltration and Infiltration Characteristic Times
2022
In his seminal paper on the solution of the infiltration equation, Philip (1969), https://doi.org/10.1016/b978-1-4831-9936-8.50010-6 proposed a gravity time, tgrav, to estimate practical convergence time and the time domain validity of his infinite time series expansion, TSE, for describing the transient state. The parameter tgrav refers to a point in time where infiltration is dominated equally by capillarity and gravity as derived from the first two (dominant) terms of the TSE. Evidence suggests that applicability of the truncated two-term equation of Philip has a time limit requiring higher-order TSE terms to better describe the infiltration process for times exceeding that limit. Since …
An experimental investigation of claimed self-handicapping strategies across motivational climates based on achievement goal and self-determination t…
2020
The purpose of the present experiment was to investigate whether the motivational climates (MCs) drawn from achievement goal and self-determination theories would affect perceived competence and the use of claimed self-handicapping. Specifically, this study examined the effects of performance MC, mastery MC and need-supportive MC on these two variables. In the context of high school physical education, 37 participants had the opportunity to claim handicaps before performing an isometric resistance task in a given MC. This procedure was repeated three times at one-week intervals so that all participants were assigned to each of the three MCs. Consistent with our hypotheses, students claimed …
Las competencias en TIC del profesorado. Influencia de factores personales y contextuales
2011
Las competencias del profesorado en las Tecnologías de la Información y la Comunicación siguen siendo un elemento crucial para el desarrollo educativo. Este trabajo pretende establecer un marco que permita concretar las relaciones de los dos elementos competenciales (tecnológico y pedagógico) y analizar la influencia de factores personales y contextuales clave. La información se ha recogido a partir de un cuestionario en una muestra de 868 profesores de educación primaria y secundaria en la Comunidad Valenciana (España). Los resultados muestran la importancia de un enfoque multivariado para valorar la complejidad del problema. Aportan una visión de las influencias de los diversos factores p…
Predicting Mathematics Achievement in Secondary Education: The Role of Cognitive, Motivational, and Emotional Variables.
2020
Academic achievement in general, and in mathematics in particular, is positively associated not only with cognitive abilities, but also with emotional and motivational skills. The objective of this study was to analyze the prediction strength of cognitive, motivational, and emotional variables in mathematics achievement throughout high school, considering students' gender and age. A large sample of 2,365 Spanish students from the 4 years of high school (12-16 years old) participated in the study. Students provided information about their intellectual skills, perceived competence in mathematics, perceived utility of mathematics, intrinsic interest in learning, mathematics anxiety, and their …
