Läxhjälp ett hån mot lärarnas kompetens

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?

On Family, Work, Money, and Morals: Intergenerational Value Differences in China

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

Allergy to methyltetrahydrophthalic anhydride in epoxy resin workers

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

Optimum combining for time-hopping impulse radio UWB Rake receivers

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

Fire Safety Risk Analysis of a Health Care Facility

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
