Potential effects of transgenic cotton on soil ecosystem processes in Vietnam.

2008

This chapter concentrates on the potential effects of transgenic cotton on the soil ecosystem of three major cotton growing areas in Vietnam: the coastal lowlands region, the central highlands (eastern and western Truong Son Mountain Range) and the south-eastern region. Soils in these three regions are very different, so it will be necessary to assess the effects of transgenic cotton on typical soils from all three regions. The soils in the south-eastern region are Luvisols, Andosols and Acrisols. In the central highlands, the soils are mainly Luvisols, Rhodic Ferrasols and Haplic Acrisols. The soils in the coastal lowlands region are mainly delta soils, consolidated occasionally by grey li…

How many longitudinal covariate measurements are needed for risk prediction?

2014

Abstract Objective In epidemiologic follow-up studies, many key covariates, such as smoking, use of medication, blood pressure, and cholesterol, are time varying. Because of practical and financial limitations, time-varying covariates cannot be measured continuously, but only at certain prespecified time points. We study how the number of these longitudinal measurements can be chosen cost-efficiently by evaluating the usefulness of the measurements for risk prediction. Study Design and Setting The usefulness is addressed by measuring the improvement in model discrimination between models using different amounts of longitudinal information. We use simulated follow-up data and the data from t…

First Year Computing Students' Perceptions of Authenticity in Assessment

2017

The problem of how best to assess student learning is a fundamental one in education. Changes to computer science curricula seek to emphasise teaching practices that promote deep learning through direct, contextual examination of student performance on tasks that resemble those of practitioners, rather than more traditional methods. This kind of "authentic assessment" is becoming more popular as it appears to incorporate employability skills associated with professional practice into the curriculum in a natural way. In this paper, we report on an investigation into how computing students themselves understand the terminology of authentic assessment. We give a brief summary of some of the sa…

Arviointi ja palautteenanto ovat oleellisia asioita opettajan jokapäiväisessä työssä. Lisäksi asenteiden tutkiminen on tällä hetkellä suosittu tutkimusala. Tässä tapaustutkimuksessa tutkittiin, millaista vuorovaikutuksellista palautetta opettaja antaa oppilailleen alakoulun englannin kielen tunneilla, ja millainen yhteys sillä on oppilaiden asenteisiin englannin kieltä kohtaan. Tutkimusaineisto koostui kolmesta opettajasta ja heidän oppilaistaan; yksi englannin kielen aineenopettaja ja hänen viidesluokkalainen ryhmänsä sekä kaksi luokanopettajaa ja heidän neljäs- ja viidesluokkalaisensa. Tutkimusaineisto koottiin metodisella triangulaatiolla. Aluksi oppilaille teetettiin kartoittava kysely …

Valutazione tra pari all’università: due approcci didattici a confronto

2020

Nell’ambito della didattica universitaria occorre rinnovare e diversificare gli strumenti di valutazione includendo sempre più anche tecnologie progettate per la valutazione. Il presente contributo mira a contribuire alla riflessione sulle pratiche didattiche che risultano più efficaci per l’integrazione delle nuove tecnologie per la valutazione formativa e la valutazione tra pari in università. In particolare si vuole verificare se l’utilizzo di tali forme valutative tramite la piattaforma Peergrade sia più efficace in un approccio didattico basato sull’interazione face-to-face o su interazioni a distanza tra una lezione e la successiva. La ricerca, condotta su un campione di 203 studenti …

Contributions to risk injury evaluation of human skin contact caused by welding technology in mechanical engineering a company

2017

Assembly by welding is a very important pollutant technological process, mainly of the atmosphere and soil. The formation of gas in welding process is the result of electrodes, fluxes burning, formation of fused bath and welded seam. A large number of human operators feels different adverse effects on health. Most problems appears in respiratory system and include bronchitis, respiratory irritation, fever caused by smoke, changes in lung function, decreased immunity to infection and a possible increase of lung cancer risk. Very little information are available about effects on the organism and skin after exposure to fumes from welding, therefore. In this order, this paper do a risk assessme…

The utilization of primary healthcare services among frail older adults – findings from the Helsinki Birth Cohort Study

2022

Abstract Background The impact of frailty on primary healthcare service use, especially general practice office visits and remote contacts, is currently unknown. Further, little is known about the association of frailty with physiotherapy contacts. Methods We examined the utilization of primary healthcare services among 1064 participants from the Helsinki Birth Cohort Study between the years 2013 and 2017. Frailty was assessed based on Fried’s frailty criteria at mean age of 71.0 (2.7 SD) years in clinical examinations between the years 2011 and 2013. General practice office visits and remote contacts, the total number of general practice contacts, physiotherapy contacts, and the total numb…

Toward modernizing the systematic review pipeline in genetics: efficient updating via data mining

2012

Purpose: The aim of this study was to demonstrate that modern data mining tools can be used as one step in reducing the labor necessary to produce and maintain systematic reviews. Methods: We used four continuously updated, manually curated resources that summarize MEDLINE-indexed articles in entire fields using systematic review methods (PDGene, AlzGene, and SzGene for genetic determinants of Parkinson disease, Alzheimer disease, and schizophrenia, respectively; and the Tufts Cost-Effectiveness Analysis (CEA) Registry for cost-effectiveness analyses). In each data set, we trained a classification model on citations screened up until 2009. We then evaluated the ability of the model to class…
