The third year systems development group project forms an essential part of the Information Systems major at the University of Cape Town. The field of Information Technology / Information Systems requires the maintenance or development of large information systems which often involves complex tasks. As effective teams are at the core of high performance organizations exposure to teamwork is imp...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Cultivar development in alfalfa relies on heterosis, that has been mainly exploited by intercrossing selected clones from diverse gemplasm sources; an alternative way was proposed, based on developing double cross cultivars obtained by crossing clones selected for self-sterility, propagated by somatic seed. A differen...

A rapid and sensitive analytical method using pentafluorothiophenol (PFTP) derivatization was applied to detect diphenylarsinic acid (DPAA) in water. In this study, the optimum derivatization conditions, such as acid concentration, reaction time and reaction temperature, were investigated to develop a suitable procedure for DPAA determination. After extracting the derivatives into benzene, the ...

In this age of modern era, the use of internet must be maximized. Yeah, internet will help us very much not only for important thing but also for daily activities. Many people now, from any level can use internet. The sources of internet connection can also be enjoyed in many places. As one of the benefits is to get the on-line selected areas in cryptography 11th international workshop sac 2004...

We test the hypothesis that the treatment of drug addicts reduces consumption of hard drugs by comparing the change in drug consumption of treated addicts before and after treatment with the change in drug consumption with demographically similar untreated addicts. If treated drug addicts are positively self-selected, naïve treatment evaluations that ignore self-selectivity into treatment will ...

Blockers of vents in ultra-low-yield cigarettes had higher levels of carbon monoxide (CO) and salivary cotinine than did nonblockers. None of the blockers reported that they blocked vents. Exposure differences seemed not to be due simply to vent blocking, but also to be the result of syndromes of heavier (blocking, more cigarettes per day, and starting earlier in the morning) or lighter smoking...

We present results from an online experiment with the goal of nudging users towards stronger passwords. We explored the effect of suggesting different variations and constellations of passwords during password selection. In particular, we investigated whether the decoy effect can be applied here: When people face a choice between two options, adding a third, unfavorable option can influence the...

In this paper I sketch a rough taxonomy of self-organization which may be of relevance in the study of cognitive and biological systems. I frame the problem both in terms of the language of secondorder cybernetics as well as the language of current theories of self-organization and complexity. The goal of establishing such a taxonomy is to allow for a classification of different tools used both...

Neurological injuries, such as stroke, result in weakened neural connections to distal muscles, specifically those that act about the ankle. Consequently, post-stroke patients experience gait deficiencies, which reduce stability and increase the overall energetic cost of walking [1,2]. Gait rehabilitation techniques have been developed to help patients relearn normal gait patterns by encouragin...
