Skills Training: Public Policy Aspects

This article describes factors influencing investments in skills training as well as related outcomes in terms of participation rates and benefits on an individual and societal level. Market mechanisms largely drive human capital investments. According to this logic, workers and employers conduct a cost–benefit analysis, weighing expected payoffs against expected costs and investing accordingly. A

For Kevin's Sake

The idiom ‘for someone’s sake’ plays a central role in recent attempts to understand the distinction between impersonal values and personal values—e.g. between what is valuable or good, period, and what is valuable for or good for someone. In the first section three historical approaches to this distinction are outlined. Section 2 presents a modified fitting-attitude (FA) analysis of final ‘value-

Neural vision sensors for surface defect detection

Vision sensors are built from a camera and intelligent hardware and/or software. Steadily decreasing microelectronic costs have spawned a large number of vision sensory applications, such as surface defect detection. A constructive method for defect detection entails a mixture of mathematical and intelligent modules. Such a heterogeneous modular system can be realized in many ways. In this paper w

Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

Popular Abstract in Swedish Genteknik innebär stora möjligheter att förändra och förbättra organismers egenskaper. Genom att i en organism föra in en främmande gen kan man ge den helt nya egenskaper som den aldrig skulle ha förvärvat på naturlig väg. Genmodifierade bakterier odlas idag industriellt i stora bioreaktorer för tillverkning av olika proteiner, till exempel insulin till diabetiker, humaVitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. In several organisms, expression of VHb has been shown to increase microaerobic cell growth and enhance oxygen-dependent cell metabolism. Moreover, the presence of V
