FRIPON: a worldwide network to track incoming meteoroids
2020
Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important limiting factor as the most fragile - hence precious - meteorites must be recovered rapidly to avoid their alteration. Aims. The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receiver…
Bodily Flashes of Dancing Women: Dance as a Method of Inquiry
2003
In May 1997 I was in Nicaragua researching a dance ritual known as May Pole. The act of dancing itself became a method of inquiry in my research process. This article concentrates on the interaction of two dancing women, Evelyn and me. My dance experience has acquired different interpretations in relation to time and context as I have reflected on it. I also enrich this experience with other dance experiences to explore my dancing body in its different forms. This hermeneutical starting point creates the conditions for trusting my instrument, my body, as a source of bodily knowledge.
An English teacher's ways of motivating students in Dangerous Minds and Dead Poets Society
2014
Pedagogiikassa ja kielenopetuksen tutkimuksessa on jo vuosia painotettu motivaation merkitystä sekä oppilaille että opettajille ja motivaation vaikutusta oppimiseen. Motivaatiota on tutkittu laajasti ja monipuolisesti samoin kuin vaikuttavia tekijöitä oppilasmotivaatiossa, mutta englannin opettajan keinoja motivoida oppilaita ei ole tarkasteltu samalla aktiivisuudella. Täydentääkseen tätä tutkimuskenttää tämä tutkielma tutkii nimenomaan englannin opettajien keinoja motivoida oppilaita esitettynä elokuvissa Dangerous Minds sekä Dead Poets Society. Tutkimus keskustelee myös siitä, voidaanko näitä keinoja soveltaa käytännön opetustyöhön ja kuinka hyvin nämä keinot vastaavat motivoivan opetukse…
High Pressure Liquid Chromatographic Analysis of Barbiturates in the Picomole Range by Fluorometry of Their DANS-Derivatives

Biases in study design, implementation, and data analysis that distort the appraisal of clinical benefit and ESMO-Magnitude of Clinical Benefit Scale…
2021
BACKGROUND: The European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS) is a validated, widely used tool developed to score the clinical benefit from cancer medicines reported in clinical trials. ESMO-MCBS scores assume valid research methodologies and quality trial implementation. Studies incorporating flawed design, implementation, or data analysis may generate outcomes that exaggerate true benefit and are not generalisable. Failure to either indicate or penalise studies with bias undermines the intention and diminishes the integrity of ESMO-MCBS scores. This review aimed to evaluate the adequacy of the ESMO-MCBS to address bias generated by flawed design, im…
Maternal body mass index, gestational weight gain, and the risk of overweight and obesity across childhood: An individual participant data meta-analy…
2019
Background Maternal obesity and excessive gestational weight gain may have persistent effects on offspring fat development. However, it remains unclear whether these effects differ by severity of obesity, and whether these effects are restricted to the extremes of maternal body mass index (BMI) and gestational weight gain. We aimed to assess the separate and combined associations of maternal BMI and gestational weight gain with the risk of overweight/obesity throughout childhood, and their population impact. Methods and findings We conducted an individual participant data meta-analysis of data from 162,129 mothers and their children from 37 pregnancy and birth cohort studies from Europe, No…
Uncertainty evaluation in power measurements with commercial data acquisition boards
2011
The paper deals with the metrological characterization of a digital wattmeter developed by using a personal computer, a shunt, two commercial data acquisition boards and commercial software. The uncertainty of the active power measurements is assessed individually characterizing the voltage channel, the current channel and the phase displacement measurement between the two channels. In particular, the uncertainty on the voltage and current rms measurements is evaluated by using an already proposed approach based on the Monte Carlo method and on the usage of five parameters, while the uncertainty on the phase angle is experimentally estimated. In order to validate the proposed approach for t…
Cruise passengers' expenditure at destinations: Review of survey techniques and data collection
2020
Spending by cruise passengers constitutes an important contribution to the economy of destinations. The issues related to the analysis of the expenditure have been widely debated for many years both in the scientific literature and in the common political debate. Despite 20 years of empirical research on this topic, not consolidated quantification methods exist to inform the debate. This work offers a brief review of the principal research on cruise tourist spending. It analyses the main characteristics of the surveys, reviews the different methods and techniques employed as well as assesses the main results. The article concludes with a discussion of the studies conducted and identifies fu…
Comparison between complete and simplified methods for determining the microwave noise parameters of HEMTs
1994
Modem automatic noise parameter measuring systems are based on measurements of some values of F(rs ) for different values of IГs (more than four, for redundancy) realized by adjusting an admittance transformer (tuner) inserted between the noise source and the TUT mput . Such values are then manipulated by means of proper data processing techniques using eqn.( 1) [ 11. This measuring procedure is hereafter referred to as standard to point out that the old `Standards on methods of measuring noise in linear twoports´ published by the IRE Subcommittee on noise in 1960 is considered obsolete by all the experimenters.
A New Approach to Investigate Students’ Behavior by Using Cluster Analysis as an Unsupervised Methodology in the Field of Education
2016
The problem of taking a set of data and separating it into subgroups where the ele- ments of each subgroup are more similar to each other than they are to elements not in the subgroup has been extensively studied through the statistical method of cluster analysis. In this paper we want to discuss the application of this method to the field of education: particularly, we want to present the use of cluster analysis to separate students into groups that can be recognized and characterized by common traits in their answers to a questionnaire, without any prior knowledge of what form those groups would take (unsupervised classification). We start from a detailed study of the data processing need…
