Inclusion of pupils with ADHD symptoms in mainstream classes with PBS

2017

Inclusion is never only a practical issue of placement. School-wide systemic change, together with well-functioning, multi-tiered support, can promote the inclusion of all pupils. This paper draws on research conducted in two mainstream primary schools in Finland. The primary focus was to gain insight into practical solutions to facilitate the inclusion of pupils with attention-deficit hyperactivity disorder (ADHD) in mainstream teaching. Using an experimental, multiple-baseline, single-case design, we examined the effects of Check-in Check-out (CICO) support on changes in the behaviour of two pupils who displayed ADHD-type behaviours. The key features of CICO are brief morning and afternoo…

Is a female physical empowerment campaign effective in improving positive body image, motivation for physical activity, and physical activity behavio…

2022

This Girl Can is a campaign designed to empower women to increase physical activity. The campaign uses images/videos of women of diverse body weights/shapes, ages and ethnicities being physically active, emphasizing body functionality. First, we examined the effects of multi-session (N = 3) exposures to This Girl Can on body functionality, body appreciation and self-compassion (Study 1). Second, we explored if autonomous motivation for physical activity mediated effects of This Girl Can on physical activity (Study 2). Women (Study 1: N = 186, M (SD) age = 27.55 (14.01); Study 2: N = 153, M (SD) age = 28.31 (11.70)) were randomized to This Girl Can, or control videos/images depicting idealiz…

Check in–check out intervention for supporting pupils’ behaviour: effectiveness and feasibility in Finnish schools

2018

Check In–Check Out (CICO) is a support programme for students with externalising problem behaviours. This study implemented in Finland is one of the first reports on the application of CICO in the European context. An experimental, multiple-baseline, single-case design is used to examine the effects of the CICO intervention on the problem behaviour and appropriate behaviour of three general education primary school pupils. The similarity of the observation data and the information provided in daily report card (DRC) are investigated to gauge the validity of the DRC assessments. The fidelity and social validity of the intervention are also analysed. CICO reduced problem behaviour in all pupi…

A Survey of Active Learning for Quantifying Vegetation Traits from Terrestrial Earth Observation Data

2021

The current exponential increase of spatiotemporally explicit data streams from satellite-based Earth observation missions offers promising opportunities for global vegetation monitoring. Intelligent sampling through active learning (AL) heuristics provides a pathway for fast inference of essential vegetation variables by means of hybrid retrieval approaches, i.e., machine learning regression algorithms trained by radiative transfer model (RTM) simulations. In this study we summarize AL theory and perform a brief systematic literature survey about AL heuristics used in the context of Earth observation regression problems over terrestrial targets. Across all relevant studies it appeared that…

Can recreational scuba divers alter natural gross sedimentation rate? A case study from a Mediterranean deep cave

2010

Abstract Di Franco, A., Ferruzza, G., Baiata, P., Chemello, R., and Milazzo, M. 2010. Can recreational scuba divers alter natural gross sedimentation rate? A case study from a Mediterranean deep cave. – ICES Journal of Marine Science, 67: 871–874. Submarine caves are environments with features distinguishing them from other littoral habitats but, despite their ecological importance, their response to anthropogenic disturbance has been seldom verified. One potential threat affecting natural communities within caves is represented by recreational scuba diving. Divers' disturbance within marine caves is mainly related to physical contacts and increased sediment resuspension potentially affecti…

Contribution to the study and to the optimization of active thermographic process applied to surface crack detection

2017

The aim of this work is the detection of open and subjacent defects in metallic materials using laser-material interaction coupled with infrared thermography. This process is a possible alternative for magnetic particles testing and dye penetrant testing in the field of non-destructive testing. This work is divided into three main parties. At first, we have been interested in the characterization of optical and thermophysical properties of materials we used, in order to have good boundary conditions and also for the needs of temperatures fields measurements for validation. The second part concern the development of a numerical simulation model with two step approach: the first involves mode…

Design of experiment approach for the optimization of polybrominated diphenyl ethers determination in fine airborne particulate matter by microwave-a…

2015

Abstract A sensitive and selective procedure for the determination of 12 polybrominated diphenyl ethers (BDE-28, BDE-49, BDE-47, BDE-66, BDE-100, BDE-119, BDE-99, BDE-155, BDE-154, BDE-153, BDE-139 and BDE-183) in airbone particulate matter (PM2.5) at trace level has been developed. The proposed method includes extraction PM2.5-bound PBDEs by microwave-assisted extraction (MAE) followed by gel permeation chromatography (GPC) clean-up and determination by GC-MS/MS using a programmed temperature vaporizer (PTV) in large volume injection (LVI) mode to introduce the sample to the chromatographic system. A design of experiment (DoE) approach was used for the optimization of large volume injectio…

A Bayesian analysis of classical hypothesis testing

1980

The procedure of maximizing the missing information is applied to derive reference posterior probabilities for null hypotheses. The results shed further light on Lindley’s paradox and suggest that a Bayesian interpretation of classical hypothesis testing is possible by providing a one-to-one approximate relationship between significance levels and posterior probabilities.

What Bayesians Expect of Each Other

1991

Abstract Our goal is to study general properties of one Bayesian's subjective beliefs about the behavior of another Bayesian's subjective beliefs. We consider two Bayesians, A and B, who have different subjective distributions for a parameter θ, and study Bayesian A's expectation of Bayesian B's posterior distribution for θ given some data Y. We show that when θ can take only two values, Bayesian A always expects Bayesian B's posterior distribution to lie between the prior distributions of A and B. Conditions are given under which a similar result holds for an arbitrary real-valued parameter θ. For a vector parameter θ we present useful expressions for the mean vector and covariance matrix …
