‘Disability Gain’ and the Limits of Representing Alternative Beauty

2018

In this conversation, Ann Fox, Matthias Krings and Ulf Vierke debate the concept of ‘disability gain’ and the limits of representing alternative beauty. The concept demands that we regard disability inclusion as a resource gain, instead of a resource drain. While this approach complicates and questions the societal definition and devaluation of ‘disability,’ it also raises a number of debatable issues. For example, what happens when ‘disabled’ bodies are commodified in an attempt to represent so-called alternative beauty? The conversation shows that, while the stakes for the fashion-beauty industry in extending aesthetic norms, pluralizing beauty and mainstreaming diversity are high, it man…

Teacher satisfaction at the educational placement of students with special educational needs

2016

This study conducted a large-scale survey to investigate the satisfaction of Finnish primary school teachers toward the current educational placement of their students with special educational needs (SEN). Teachers were asked to recommend the most suitable educational placement for each of their SEN students from a pool of six alternatives: a mainstream classroom, part-time special education, a special classroom in the mainstream school, a special school, a state special school, or an institution. Data were obtained from 980 students representing 68 schools. The results showed that, in the majority of cases, teachers recommended a different level to the current level of placement for their …

Positive teacher attitudes are essential for success when children with special educational needs (SEN) are placed into mainstream classrooms. The present study surveyed teachers’ attitudes towards...

Making meaning of inclusive education: classroom practices in Finnish and South African classrooms

2017

AbstractThis paper reports on the findings of an international comparative research project where the roles of teachers in the implementation of inclusive education in mainstream-classroom settings in South Africa and Finland were investigated. Inclusive education within this project is broadly defined as welcoming all students to general-education schools and classrooms and not segregating students on the basis of ability or other individual or sociocultural characteristics. In this paper a qualitative analysis of Finnish and South African teachers’ day-to-day teaching and learning support practices in their classroom is discussed. Individual and focus-group interviews encouraged teachers …

Using WMS log files as an indicator of QoS and application performance in on-demand streaming videos

2012

When utilizing video streaming for professional purposes, the quality of service needs to be evaluated by the service provider. This is the case especially when the service must be available for a large number of customers with a wide range of network interfaces and terminal equipment. Service providers have usually information about network-level metrics. However, the problem is that conditions that appear similar in a networklevel may cause very different responses in an application level, and the other way round. In this article, we study how Windows Media Server's log files can be used to evaluate the QoS of video transmission, and we also examine the application level performance based…

An interest-aware video streaming platform: Shaping its architecture to better suit users' demands

2014

This paper investigates how a p2p television platform can take advantage of the presence of frequent channel viewers to grant them a more satisfying service than to less regular spectators. The idea we explore is to learn beforehand about the users’ interests, in order to cluster them in groups that display different behaviors; then, the video chunk scheduling algorithm of the p2p overlay is altered, with the aim of serving frequent spectators in a privileged manner, providing them with a faster access to the selected channel. An analytical model is developed, to capture the difference in startup delay that the proposed changes introduce; several additional performance metrics are numerical…

Online Principal Component Analysis in High Dimension: Which Algorithm to Choose?

2017

Summary Principal component analysis (PCA) is a method of choice for dimension reduction. In the current context of data explosion, online techniques that do not require storing all data in memory are indispensable to perform the PCA of streaming data and/or massive data. Despite the wide availability of recursive algorithms that can efficiently update the PCA when new data are observed, the literature offers little guidance on how to select a suitable algorithm for a given application. This paper reviews the main approaches to online PCA, namely, perturbation techniques, incremental methods and stochastic optimisation, and compares the most widely employed techniques in terms statistical a…

A set-up for simultaneous measurement of second harmonic generation and streaming potential and some test applications.

2018

We present a measurement cell that allows simultaneous measurement of second harmonic generation (SHG) and streaming potential (SP) at mineral-water interfaces with flat specimen that are suitable for non-linear optical (NLO) studies. The set-up directly yields SHG data for the interface of interest and can also be used to obtain information concerning the influence of flow on NLO signals from that interface. The streaming potential is at present measured against a reference substrate (PTFE). The properties of this inert reference can be independently determined for the same conditions. With the new cell, for the first time the SHG signal and the SP for flat surfaces have been simultaneousl…
