Läxhjälp bör bygga på att det är kvalificerad personal som svarar för verksamheten. I debatten om rut-avdrag har två viktiga frågor inte ställts: 1. Varför har svenska skolan hamnat i en situation av sviktande måluppfyllelse? 2. Varför ska de som behöver extra stöd, oberoende av vilken nivå de ligger på studiemässigt, inte få den mest kvalificerade hjälpen, det vill säga utbildade lärare?
In which ways has China‘s rapid social change crystallized into differences between its generations’ values? The significance of intergenerational value gaps in values involving work,family, materialism, and individualism is reported based on a mixed-methods approach. A set of qualitative interviews with businessmen and their fathers was conducted in Shanghai in late 2005. Semi-structured intervie
One hundred and forty four current and 26 former workers in a plant producing barrels for rocket guns from an epoxy resin containing methyltetrahydrophthalic anhydride (MTHPA; time weighted average air concentration up to 150 uglm') were studied. They showed higher frequencies of work related symptoms from the eyes (31 v 0%; p < 0-001), nose (53 v 9%; p < 0-001), pharynx (26 v 6%; p < 0-01), and a
In this paper, we present results on the application of reduced-rank adaptive filtering techniques to the problem of interference suppression in ultra-wideband (UWB) communications. It is shown that reduced-rank optimum combining (OC) methods, in particular the eigen-canceler (EC), are effective in suppressing interference modeled as 802.11a signals. Simulation results are presented to show that t
A methodology for deriving individual risk to people in a health care facility due to fire, is presented. The risk is expressed by the First Order Second Moment reliability index ß. The evacuation time for the patients is compared to the time to untenable conditions arise. Subjecting variables to uncertainty results in a reliability index value for the escape time margin. The influence on reliabil
We present a method for studying large finite periodic structures using soft- ware developed for infinite periodic structures. The method is based on the Floquet-Bloch transformation, which splits the spatial description into one microscopic spatial variable inside the unit cell, and one macroscopic wave vector describing the variations on a scale encompassing many unit cells. The resulting algori
The ICAO approach to risk management is essentially a technical model based on an engineering process viewpoint and is more applicable in concept to stable systems, such as chemical and nuclear industries. If airlines are to manage risk in a proactive manner they need to apply risk detection tools that provide real time and continuous systems oversight. This paper describes briefly the systems ap
